Re: ColdFusion 9 on Java 8
You may find the jump from CF9 to CF10/11 to require changes to your app. I know the change for us was not straightforward. Make sure you plan for an extensive QA cycle after upgrading. One of the biggest issues we ran into was with date/time conversions. We store everything in UTC. Adobe changed the internals of the way that dates converted to UTC work that can cause issues with some types of date mathematical operations (like using the results of a createTimeSpan() to adjust a date.) We found a number of things that made our upgrade from CF9 to CF10 slow. On Thu, Mar 12, 2015 at 10:59 AM, Scott Stewart webmas...@sstwebworks.com wrote: Wil, that's what I'm pushing for.

Re: Advise in optimizing an application
You need to turn use some debugging tools to help you identify the key culprits. For example, if your query to check if a user has unsubscribed is taking 500ms, that alone would be the reason for the slowness. Either use the step debugger, a tool like FusionReactor or just turn on verbose debugging output, so you can understand your current bottleneck. It's very possible you have some inefficiencies in some of your SQL lookups (do to missing indexes, etc) that would cause slowness over lots of loops. You might look into using Java libs to read in the Excel file more efficiently.

Basically, it works pretty well, as long as there's a limited number of records being imported. Problem is, the client tried to import a list with almost 15,000 addresses today, and it eventually timed out or the server reset the connection before it finished the import. Then my phone rings... The app does several things: 1. Import 4 columns from an excel sheet [email][first name][last name][company] into an array 2. Check the email address to see if it's valid. If not, delete that row from the array 3. Check the email address to see if it's been previously unsubscribed from the list and delete that row from the array 4. Check the list against other email addresses already in the database for that list, and delete that row so as to not import it if it's already there. 5. After all that, write the record Running some test with the 15,000 address sheet Reading the Excel sheet in and running steps 1 through 4 above is taking well over 10 minutes by itself. Writing the record after that, enough extra time to be sure it borks up.

Re: CF 9 and Java 1.7 ?

Things have been fine since rolling back.

Re: Mobile
While user agent can be spoofed (and pretty easily with most browsers), the reality is it's not a problem you need to worry about. You do generally want to try and avoid user agent when possible, but if your trying to detect the device purely on the server, there really isn't another option. Any kind of client side detection (such as screen width) will require and least a two trips to the server--once to serve up the client-side code that detects the device, then you hit the server again to change the layout.

Subject: CF 9.01 with Cumulative hot fix 4 won't work with Java 1.7
Hi all,
I have a strange dilemma with a new install of ColdFusion 9 Enterprise on
Windows 2008 R2.
I have a server that is being swapped out, so on the new server I
installed CF9 then applied the cf901 updater. After that I applied
Cumulative hot fix 4. I needed this configuration because we still have
some Verity collections.
The problem comes when I try to use Java 1.7. I have changed
java.home=E:\\Java\\jdk1.7.0_17\\jre and java.home=E:/Java/jdk1.7.0_17/jre
but both error out (see errors below). This is 64-bit Windows, 64-Bit
ColdFusion and 64-Bit Java.
I have also tried E:\\Java\\jre7 and E:/Java/jre7 using just the JRE and
those error as well.
It is always stating that the file does not exist even though the file is
there.
Here are the Errors: (from the *-out.log)
For E:\\Java\\jdk1.7.0_17\\jre - Error loading:
E:\Java\jdk1.7.0_17\jre\bin\server\jvm.dll
For E:/Java/jdk1.7.0_17/jre - Error loading
E:/Java/jdk1.7.0_17/jre\bin\server\jvm.dll
For E:/Java/jre7 - Error: no known VMs. (check for corrupt jvm.cfg file)
For E:\\Java\\jre7 - Error: no known VMs. (check for corrupt jvm.cfg file)
When I look at the Windows System Log for the Error Loading errors it has:
The Macromedia JRun CFusion Server service terminated with
service-specific error The system cannot find the file specified..
The file does exist I have verified it more than once.
The only configuration that is working is when java.home=E:/JRun4/jre in
the jvm.config file.
I'm stumped with this one and would really appreciate any insight.
Thanks,
Steve

You could then use that backup to create native 2005 databases anytime you need one. -Dan On Friday, September 14, 2012, Mike Kear wrote: OK, thanks everybody.I think I am fairly sure I'm going to be able to load up anything I might develop in the future onto that client's 2005 server.

I actually built an implementation for CF8 (probably would work in CF7 too) that also fixed some of the bugs/issues w/the CF9 implementation due to how they parse out the params (but it uses the same syntax.) Unfortunately, I can't share the code, but the basic idea is you just parse the SQL statement and then inside a cfquery statement you walk through the parsed string, outputting the straight text or implementing cfqueryparam / when you come to a parameter statement. -Dan On Fri, Jun 8, 2012 at 4:06 AM, Helwig, Till Helge till.hel...@saxsys.dewrote: Hi guys, I'm working on a very old CF application at the moment.

Re: Best way to use cfschedule for large number of tasks
Mosh, Thanks for the reply. In the past, I've always done things via the route you suggested (a single task working off of a queue). My concern here, and it looks like I left this out of the original post, is that the tasks will be time-sensitive (but not time-critical). That is, if the task is set to run at 5:00 PM, it should run as close to 5:00 PM as possible (think calendar alert sensitive vs. giving someone scheduled medicine critical). You might want to consider running these scheduled tasks on a separate CF instance--that way the threads tied up by background tasks are going to be tying up threads of your visitors. Some other things you could try: 1) Run the background task every 60 seconds. If there are no tasks to run the overhead should really be essentially nil (you should only be dealing with a few milliseconds for any empty queue query.) 2) Use cfthread / to process multiple background tasks asynchronously. That way a single long running task won't bog down all the tasks scheduled to run on the current iteration. 3) Run multiple scheduled events (this might be better if you're running a separate instance for scheduled tasks.) You can assign tasks in a round robin fashion, so each background script would run a different set of tasks. 4) Do an asynchronous HTTP request to process the task. This is a good way to just trigger off a bunch of requests to be processed that will start right away. However, I'd only do this if you're running a separate instance for scheduled tasks. -Dan -- Dan G.

Mosh, On 5/31/2011 1:42 PM, Mosh Teitelbaum wrote: All: I'm working on a system that will have a large number of timed, one-time tasks that need to be executed on a schedule. I'm trying to figure out the best way to accomplish this with cfschedule. The two options I see are as follows: 1. A single, recurring task that runs every 5 minutes and queries the database for any tasks that need to be executed. The benefit of this approach is that there is only a single task to create. The negatives of this approach are (a) potentially querying the database when there are no tasks to execute (waste of resources) and (b) risk of too many tasks at any given time causing the scheduled execution to time out or cause later tasks in the run to be executed so late as to be off schedule. (a) The overhead of running a script that doesn't find anything to run should be extremely minimal, so I wouldn't even factor this in as a waste of resources. (b) You can always limit the number of tasks you're going to execute in one pass--that way you'll never run too many requests in a single batch. Also, depending on your needs, if you have some requests that you know are long running, you could build into your scheduling queue when a valid window for that task is to run. So, if you know a task might take 5 minutes to run (because it does a ton of warehousing, etc) you could make sure those type of events only run during non-peak hours. 2. Create a new cfschedule task for each task that needs to be run. The benefits of this approach are that it solves all of the negatives of the other approach. The negatives are that it would necessitate the creation of a very large number of cfschedule events and I don't know if this could negatively affect the scheduler or CF performance. Either approach would include code to do cleanup (e.g., delete the task from the CF scheduler after it has been executed, etc.). Any thoughts as to which approach (or a different one altogether) is better? I've always preferred having a single background task to manage a queue, rather than trying to schedule everything via cfschedule / and clean up afterwards. For one, it's much easier to catch errors. It also gives you a single point of entry/failure. You can easily build reports on your executed tasks--because you're already storing that stuff in the database. If it's important enough, you can find out how long each task is taking to execute, find which generated errors, re-queue events, etc. You can also really easily just fire off stuff in queue manually. -Dan -- Dan G.

Re: Odd issue with Query
Charlie,
If you're using MSSQL and cfqueryparam /, sometimes running a query
directly in SSMS may lead to misleading information. I wrote a blog issue a
while back that talks about one issue:
http://blog.pengoworks.com/index.cfm/2010/12/8/Performance-issues-with-cfqueryparam--on-first-execution-when-using-Microsoft-SQL-Server
Essentially what can be happening is that MSSQL is having performance
problems running sp_prepexec to analyze the best way to run your SQL, so the
problem isn't running the query, it's with MSSQL trying to figure out the
best way to run the query.
You might also check out this lengthy article:

So this was a weird one... the error is resolved, but I was wondering if
anyone could explain what was causing my error.
I had a query that was timing out (its one of those nice long monster
queries - so I'm not pasting it in its entirety) - but when I copied/pasted
out of the cfcatch.sql (from error thrown on timeout) into SQL Query
Analyzer - or another template, it completed in under a second.
In the query there was a join that looked like this -
LEFT JOIN tableA on ColX
cfif condition...
= ColY
cfelse
= ColZ
/cfif
Changing it to either of the following resolved the issue
Solution 1:
LEFT JOIN tableA on ColX cfif condition...
= ColY
cfelse
= ColZ
/cfif
Solution 2:
cfif condition...
LEFT JOIN tableA on ColX = ColY
cfelse
LEFT JOIN tableA on ColX = ColZ
/cfif
So I'm assuming there was something going on related to the carriage return
following ColX - and in addition to the two solutions above, the process
of copy-pasting also must have resolved it.
If it makes any difference - I'm using SeeFusion for monitoring and so all
my datasources use:
JDBC URL:
jdbc:seefusion:jdbcwrapper:{jdbc:macromedia:sqlserver://server1:1433;
databaseName=dbname; SelectMethod=direct;
sendStringParametersAsUnicode=false; MaxPooledStatements=1000};
Driver Class: com.seefusion.Driver
Anyone have any idea on the root problem?
Thanks!

Re: SOT: SQL CTE update
Jason, That's why I said to sort the tree in using DESC instead of ASC on the Depth column: - - -*Drivers *(3) - -Software (2) -Support (1) Home (0) If you pull in descending order, you'll know the max depth from the first row, so if it's a matter of using the depth for indenting, just use: maxDepth-depth to reverse the depth. -Dan On 3/29/2011 3:34 PM, Jason Durham wrote: The in example I posted, I'm calculating the depth in the select statement. The depth is determined by the order in which the row is returned. If I start from a child, the child is returned first (therefore it's 0).

Re: What event specifically triggers OnApplicationStart?
One thing to keep in mind, if you do not have a *unique *ApplicationName on your server, then the variables could be shared w/another application--which is especially dangerous on shared hosting. I've seen people roll out an application w/a common ApplicationName like MainApp and have issues w/their App scope being shared w/another application that also used a name of MainApp. Same thing happens if the Application.cfc/cfm doesn't define a ApplicationName. IMO, the safest thing you can do is name define ever ApplicationName with a hash of the current directory path: cfset this.name = hash(getDirectoryFromPath(getCurrentTemplatePath())) / That way you can use the same code w/every Application.cfc, but your virtually guaranteed to have a unique ApplicationName. -Dan On Mon, Mar 28, 2011 at 2:55 PM, Russ Michaels r...@michaels.me.uk wrote: I think I can see one possible cause of your problem Dave.

So perhaps most people go to www.yourdomain.com, but every so often someone visits yourdoamin.cominstead, which would restart the application if it was outside the timeout period. To avoid this you need to add a redirect, so that only 1 domain is in use. either redirect www.yourdoamin.com to yourdomain.com or vice versa.

Re: Database Lookup - Possible with CF?
I also posted already posted an example for Ian showing the jQuery/CF7 portion of the code: http://blog.pengoworks.com/index.cfm/2011/3/3/Easy-AJAX-using-ColdFusion-jQuery-and-CFCs The example does deal w/a struct, but converting data to a struct is very straightforward. I know he's seen it--because we had an offlist brief discussion. The only piece of the puzzle he needs to work out is the web service part--which may end up being extremely easy, or extremely difficult--depending on the web service he's trying to consume. If CF7 can handle the format natively, then it's very straight forward. However, if CF7 throws errors accessing the web service, then he's going to have to find other method of consuming the web service. -Dan On 3/14/2011 9:20 AM, Dean Lawrence wrote: Ian, again you are mixing things up.CFJSON is not what calls the webservice. CFJSON is used to encode or decode native ColdFusion objects to and from JSON format. So if you if have a query result, you would pass that query object to CFJSON and it will encode it into JSON format. Vice-versa, you can pass it a JSON string and it can covert it back to a native ColdFusion object. So with that said, JQuery would make an AJAX call to your ColdFusion page, be it a .cfm or .cfc page (doesn't really matter as JQuery doesn't care). On that ColdFusion page you would invoke the webservice that you are getting your data from and make whatever calls that the webservice requires. If what you get back from the webservice is not in a JSON format, you would then pass the results to CFJSON to convert it to JSON. It is this converted data that you would then return to the original AJAX call and now use JQuery to populate your form with that data. I think your hang-up is on this whole ColdFusion 7 mentality. The use of JQuery to make an AJAX call and populate the form is not ColdFusion 7 specific, as it is a client-side task, it really has nothing to do with ColdFusion 7. The only ColdFusion 7 functionality that you really need to be concerned about is making the call to your .Net webservice. Here is Adobe's LiveDoc page that tells you how to do that. http://livedocs.adobe.com/coldfusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm?context=ColdFusion_Documentationfile=part_dev.htm As for ColdFusion 7 and JSON, JSON is really only text. Again, you don't need anything special to work with it. Projects like CFJSON simply make it easier to work with it. But if you look at the source code for CFJSON, it is just using plain old ColdFusion to process the data. The same holds true for newer version of ColdFusion. The built-in tags are just a way to make it easier to work with JSON, but are not required. I'm running ColdFusion 9.01 and don't use any of the built-in tags to do my AJAX calls as I like to have full control over the process. That's just me though.

Re: How do I get a save/download window using Ajax?
You can't download files like that via AJAX. What you can do, and what
I've done in the past, is use an iframe to push the download to the
browser.
In the past I've used AJAX to check the server to see if the
downloadable file is ready for download. I do this by creating a
unique download token that gets marked as ready right before I push
the file back in the iframe. Once my AJAX script finds the token is
marked ready I stop the AJAX script and perform my JS code.

Re: storing a cfinput inside of a variable
Steve,
Is there anyway to use cfset or cfsavecontent to store a complete cfinput
tag?
i.e.
cfset config.formFieldA = cfinput type=text name=fieldname
value=//
If I do a view source, I see it the code on my output page, but it won't
render at all in the browser.
If I try cfsavecontent it errors because the cfinput isn't in a cfform
(since the cfinput is in a CFC being called by the form page).
The reason for this is that this one form field could have different max
lengths, validations, validation patterns, and messages based on a variety
of factors. If I can move the input into a CFC that returns all sorts of
other partner specific info, it keeps me to having just one space to enter
config data.
That doesn't work, instead do something like:
cfset fieldA = {
type=text
, name=fieldname
, value=
} /
cfinput attributeCollection=#fieldA# /
You can use a structure to define the parameters for the cfinput / tag.

That will force jQuery to fire the change event handler, just as if the

Yea, I know, Word produces some of the gawd-awful bloated ... uhh, never mind - it's terrible. So, I'm looking for a new editor for them that will handle Word better. I don't care what it costs, within reason. The best product I've seen for dealing with Word is XStandard. The only gotcha is it's an ActiveX/Plug-in for the browser. Since this is an admin feature, this probably isn't a big deal, but it does involve installing a 3rd party application. The really nice thing about XStandard is that you can cut-n-paste Word documents with embedded images and you can upload the images via a web service--no need for users to upload images independently and then re-insert them. They can just paste them right into the canvas. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:317077 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

RE: The Woes of CFThread -- going out of my mind!
The memory usage of the PDF report generation is defiantly a problem. It is what we where trying to address with the usage of the thread tag. The idea being that by splitting the process into separate threads and throttle them down would allow the server time to clean up memory used in previous iterations. That is a topic for a seperate discussion. How does cfreport... work in large iterations. We found that no matter what we did, the memory used by the report tag would just climb and climb each iteration unless we broke up the process into completely separate HTTP requests. By creating a template that would process a small number of reports per request and then send a page to the browser with a META refresh to re-request the page in one second. This works fine. While certainly not ideal, what if you split things up like this: 1) You create one template that creates a report based on some kind of unique key identifier. 2) You create a second template that loops through all the reports you need to create and call the first template using CFHTTP. This should at least sort of emulate the meta refresh technique, but allows you to automate the process w/out relying on a browser for the meta refresh. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:308861 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Generally the latter will be very small unless you a) are transferring a large amount of content back to the user or b) experiencing network delays. Now, for your situation, I am unclear which of these figures is higher. If the problem is simply that pages are slowing down, then you need to figure out what they are doing. Use the JDBC url wrapper with SeeFusion to monitor your database calls. Un-optimized queries should be your primary suspect. Make sure all your data SeeFusion will tell you if a page is running a query and what SQL is being executed. Now, when you see pages start slowing down, get a stack trace for the slow request from SeeFusion and see what it is up to. Keep in mind that your databases performance can be impacted by DB jobs and/or clients other than ColdFusion accessing them. Additionally, enable SeeFusion's db logging and check out the counters table. That will tell you if you are having a surge of traffic, when your average page times jumped as well as heap size etc. That's about as far as I can get you until you look at some stack traces. I doubt the accessing of your .cfm files is what is slowing you down though. They are cached locally after their first read anyway when using trusted cache so the NAS should not even come into play after the first load of each page. ~Brad -Original Message- From: Brian Peddle [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 08, 2008 12:38 PM To: CF-Talk Subject: Time to First Byte I know without deep details this may be hard to answer but looking for some general thoughts. We have 4 front end web servers all on Coldfusion 7. Java 1.4.1.13. Dell Xeon 4 gigs of Ram, dual quad core Nothing by CF runs on these boxes. All the code lives on NAS on a gigabyte network. Throughout the day when looking at seefusion we will see short windows of time, maybe min or 2 where pages that normally load pretty quick with take 30 seconds for example to execute the TTFB. Queries are in ms range but the page just seems to stick. For some testing I moved all the source code to the local Drive on 1 web server. I do notice less pages hanging but still see little blips. What I see as a big difference is when my app first loads on the NAS it takes up to 100 seconds, locally 10 seconds or less to load in all the objects. Performance overall on the local machine seems faster. Roght now the code on the local machine sits on C drive as well so I suspect if I added some more drives it would perform a little better with having to compete with the OS. For caching I have both Trusted cache and Save Class files checked and max number of cached templates at 2000. Max is connections is at 24, I know I could go much higher but this seems to work best. I would assume overall that the site running locally will perform faster than over a gig switch. Maybe fiber would compete here, not sure. Im trying to figure out why the sporadic high TTFB comes up. Are there any other settings, places to look, IIS settings maybe, to try and see why this is happening... or is it simply a burst in traffic that causes some concurrency issues? Thanks in advance.

RE: qforms: transferring values from one select to another
Mike,
great!! thanks for that.
the following code works...
objForm = new qForm(related_product_form);
objForm.products_available.makeContainer();
objForm.products_available.dummyContainer = true;
cfoutput
objForm.products_selected.setValue('#valueList(getRelated.product_idfk)#');
/cfoutput
my problem now is that if the user decides to transfer an item back to
products_available (potentially removing focus from the other
products_selected items) then the form submits only what is highlighted in
the products_selected - which now may be nothing?
You need to make products_selected a container too:
objForm.products_selected.makeContainer(products_available);
(You don't want it a dummy container, you want it a real container.) It's
the making it a container part that tells qForms to select all the options
in the select box before submitting to the server.

RE: qforms: transferring values from one select to another
Mike,
sorry the yahoo mailing list seems to be down for qforms so thought someone
on here may be able to help.
Due to the amount of noise (aka spam) I have to approve first time posters
first. The list isn't down, I just didn't get through to approving your
message until this morning.
have simple form (2 x multiple select containers) that let you select
'related products' for a particular product.
the qforms default setup works great, but what i am trying to do is
populate the 2nd select with any existing related selections. at the
moment, these are not included in the submitted form information (unless i
transfer them back to the first select - then transfer back)???
a snippet of my code is as follows...
First select
select name=products_available size=20 multiple style=width:90%;
onDblClick=objForm.products_available.transferTo('products_selected');
cfoutput query=getProducts group=product_title
option
value=#getProducts.product_id##getProducts.product_title#/option
/cfoutput
/select
Second select (where i want any existing selections to appear)
select name=products_selected size=20 multiple style=width:90%;
onDblClick=objForm.products_available.transferFrom('products_selected');
cfoutput query=getRelated
option
value=#getRelated.product_idfk##getRelated.product_title#/option
/cfoutput
/select
my qforms code is the default...
SCRIPT LANGUAGE=JavaScript
!--//
// initialize the qForm object
objForm = new qForm(related_product_form);
// make the User field a container, this will ensure that the
reset()
// method will restore the values in the select box, even if they've
// been removed from the select box
objForm.products_available.makeContainer();
// setting the dummyContainer property to false will ensure that
no
values
// from this container are included with the value
objForm.products_available.dummyContainer = true;
// make the Members field a container--every item in the Members
select box
// will be part of the container, even if the item isn't selected.
objForm.products_selected.makeContainer();
//--
/SCRIPT
You want to use the bindTo parameter on the makeContainer() methods to
bind the 2 related select boxes together:
http://www.pengoworks.com/qforms/docs/extension_fields.htm#makeContainer
objForm.products_available.makeContainer(products_selected);
objForm.products_selected.makeContainer(products_available);
I would then use:
objForm.products_selected.setValue(existing,values,here);
To re-populate the list with the saved values. It should take care of moving
the values from one list to the next.

RE: Best way to order appearance of database content...
Rick, Say, I've got two agents in the db. First has display-order 10, second has display-order 20. A third agent is added who is to be displayed second, so is given the display-order number 15 in the form. When the form is submitted, the first agent retains number 10, the new second agent's number is rounded up from 15 to 20, and the agent whose number was 20 now has the number 30. That way there are always values between the agents' display-order numbers to add new agents. Make any sense? Would this be the best way to do this? Other ways? There's no reason to use number in multiples of 10. Just store their real order and do something like: cfset iNewUserOrder = 3 / !---// do this before inserting //--- cfquery update Employees set display-order = display-order + 1 where display-order = #iNewUserOrder# /cfquery Then ever user who's order was 3 or more is shifted up and then you can actually insert the new user at position 3. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:301154 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: Bluedragon = open source
From: Dave Watts [mailto:[EMAIL PROTECTED] See, that's exactly what i'm talking about. If another company adds a feature *before* Adobe does, then how is it not the responsibility of Adobe to maintain compatibility when they themselves add the same feature? Should the other company in question break backwards compatibility with their own code just to match Adobe's implementation? Once again we see the position that only Adobe is allowed to innovate in this area. Adobe is not selling a CFML engine. Adobe is selling ColdFusion. Adobe hasn't standardized CFML, and has no responsibility to any other vendor selling CFML engines. You can argue that those other vendors likewise have no responsibility to Adobe, and I'd agree, but if you build a product that provides compatibility with someone else's product as its chief feature, the onus is on you to provide that compatibility. I've always thought BD would have been better served by using the cfx_ extension for additions they made to the language. That would at least give developers who want to use BD as their core language the ability to write custom tags that could be implemented in other versions of CF. It would seem to address a lot of issues of compatibility... -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:301050 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

This should do what you want: http://www.pengoworks.com/qforms/ext/atLeastOne.htm You can use it like: oForm.textareaName.validateAtLeastOne(checkboxName); That should enforce that at least the textarea is filled in or one of the checkboxes is checked.

The latter gets close although it will say something like FileName.cfm (9 matches) instead of giving 9 separate links, this is where I figure I am doing something wrong and there is someway to expand that out. If you highlight a phrase, you can use CTRL+K and SHIFT+CTRL+K to cycle through instances of that phrase/word within a document. No need to even bring up the Find dialog. Also, when you do the Search feature it will automatically place gutter markers that you can click on to jump to specific points in the document (those are the little squares to the right of the editor.) You can also use the arrow keys to cycle through the instances in the Search View. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:300499 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: qForms Question
Hatton, I've inherited a form that is using qForms for validation. The form includes a series of three checkboxes, all with the same name but different values, further down there is a textarea. The client has asked for a validation rule that requires either one of the checkboxes to be checked, the textarea to contain a value or both. If the user does not check a box or enter something in the texarea, a validation message needs to appear. I know I can do this in Javascript but I'm hesitant to roll my own when qForms is already validating the rest of the form (some 15 other required fields). Is there a way to do this in qForms? This should do what you want: http://www.pengoworks.com/qforms/ext/atLeastOne.htm You can use it like: oForm.textareaName.validateAtLeastOne(checkboxName); That should enforce that at least the textarea is filled in or one of the checkboxes is checked. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:300547 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Tom, It's not a perfect solution--since you need to attach the validation to one of the fields, but that custom method will do the trick for those validate either a or b type of situations. Seems pretty good to me. So -- the method you specified will validate that EITHER one of the checkboxes is checked OR there is content in the textarea? Correct. In a nutshell it's Make sure at least one of these fields has a value. That's the sort of thing where I always added a custom validator or at least used an Expression. Are there other examples on your site, or elsewhere, that go into this sort of validation of related fields? I must have missed them.

RE: Using cfinput causes form fields to show through?
William, I looked into this (see my other post) and the z-index for the input field gets set to 0, the autosuggestcontainer gets set to 9050 and the shadow to 9049. The problem lies in that IE6 and z-index don't get along (at all). IE6 literally resets all z-index to 0 once the page loads. That's not true at all. IE doesn't reset z-index to 0 once the page loads. There are elements (such as the select and iframe elements) that actually reside outside of the context of the browser in IE6 because it used internal Windows controls--this was fixed in IE7. You can read more about that here: http://blogs.msdn.com/ie/archive/2006/01/17/514076.aspx Well there may be a problem on your page with the z-indexing and IE6, IE6 doesn't do anything to natively to reset z-indexes after the page is loaded. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:297718 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4

Jonathon, Here's a stored procedure you can use in MSSQL 2k for pagination: http://blog.pengoworks.com/index.cfm/2006/6/19/MSSQL-2k-Stored-Procedure-for -Pagination It doesn't use #temp tables and it will only return the pages of data you're after. I've used it on tables with several millions of records and had great success with it. Also, in SQL Server 2005 you can solve this problem with Common Table Expressions (CTE) -Dan -Original Message- From: Jonathon Stierman [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 02, 2008 6:01 PM To: CF-Talk Subject: mssql pagination I can't imagine I'm the first person to try to do something like this, so hopefully you guys can give me some insight! I know this isn't strictly CF-related -- but I'm hoping some of you have tried to do something like this in the past. I'm trying to produce a paginated list of records. The query I'm working with has about 2 rows, and I'd rather not force the user to sift through all those pages in a single page request. So I'd like to break it up, maybe display 50 records per page. I'd also prefer not to have the full query sitting in memory every request. If I'm only displaying rows 50-100, I only want rows 50-100 in the query object. Using cfloop with startrow and maxrows won't cut it this time. Apparently this is super easy in MYSQL using the LIMIT (records), (offset) clause. Turns in MSSQL makes things difficult. A couple sites I hit up showed examples of using of subqueries and the TOP filter, or (ugh) temporary tables. I went with the subquery/TOP approach. For example, ordering by dateAdded and wanting to show rows 20-30: SELECT TOP 10 sampleID FROM Samples WHERE 0=0 AND sampleID NOT IN ( SELECT TOP 20 sampleID FROM Samples ORDER BY Samples.dateAdded ) ORDER BY Samples.dateAdded Grab the first 10 records after eliminating the first 20 records, always sorting by dateAdded. But I found it worked sporadically. Pages 1 and 2 worked fine, displaying the 1-10 and 11-20 records respectively. But page 3 gave me some strange results. It showed records 14-23 or some other mismatch. Obviously not what I was looking for! After some investigation, I found out my subquery was not returning the right samples to exlude. What I haven't been able to figure out is *why* they are not returning the right subset. As far as I can tell, the SQL looks good to me. So my question to you guys is -- 1. Can you see anything wrong with how I've set up my Query? 2. How have you dealt with pagination in the past? Is there an easier route than what I'm taking now? PS -- I am running on MSSQL Server 2000 (I have heard they offer an OFFSET clause in 2005, but sadly, I do not have access to that). If anyone is interested in seeing some sample data of what I'm working on, I put up this HTML page: http://www.vimm.com/developerTools/sampledata.html You can see in the All Samples section that records 20-30 should be: [147, 148, 149, 150, 63, 36, 40, 382, 383, 384]. But the Total Wrapper query returns: [146, 147, 148, 149, 150, 63, 382, 383, 384, 440]. What happened to record 40? It's row #27 in the All Samples query, but it's included in the exclude Nested Subquery that should only be pulling the top 20 results. How does that happen?

RE: Exclusive locks still producing duplicate values
Dave, We have have an issue here that I thought I had solved via locking and transactions, but it appears that the issue still exists. Basically, our clients go through an order entry process that produces a numbered requisition. The number is based upon a value that is stored in the database for each client. Multiple users of the same client can obviously place orders simultaneously all drawing their base number from the same location. The section of code that actually creates the req number and stores the data is run within a serialized transaction that sits within an exclusive named lock. If I'm understanding locking correctly, the exclusive named lock should prevent any other execution of that same code within the same application. The serialized transaction should restrict access to the tables required to that single transaction, again if I'm understanding it correctly. Also, if you're generating this Request number on a page before you actually submit to database, then a user clicking the submit multiple times would generate duplicate records with the same request number. Example: on Page A you generate the request number so you can display it to the user. Page A allows the user to confirm the creation process. When the user clicks the submit button, it goes to Page B which actually inserts the data into the database. If the user clicks the submit button multiple times it can create multiple requests. Are you ever storing this request number in any scope (Session, Form, Url, etc?) Also, are you absolutely positive your code is returning unique numbers? You're locking may be working, but if there's an error in the logic you could still produce duplicate request numbers. For example, let's say you were creating a number based upon the current date time stamp: cfset dtNow = dateFormat(now(), mmdd) timeFormat(now(), HHmmss) / cflock !--// insert unique number //-- /cflock By creating the dtNow number outside of the lock, I'm opening myself up to duplicate values. This is just an example... -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294989 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: memory issues
Jonathon, Robi Sen has some excellent information on memory issues like you're experiencing: http://www.robisen.com/index.cfm?mode=entryentry=FD4BE2FC-55DC-F2B1-FED0717 CC1C7E0AF Are you using the default JRE? If so, you might consider upgrading to JRE SDK 1.4.2_13--which I believe is the most recent version that CF officially supports. Also, prior to CF8 the cffile / implementation for reading files was notoriously problematic when reading large files (although it should be ok on files from the 200K to 5MB range.) Java is just not really good with large strings--it's always been a weakness of the language. You might want to consider going straight to Java to read a file line-by-line (instead of the entire file.) Here's a UDF from CFlib that shows reading a file by line: http://www.cflib.org/udf.cfm?id=417enable=1 This might help you reduce the memory needed for each request. Lastly, make sure you're caching whatever results you can. If you're constantly parsing the same files over and over, just cache the results once you've generated them. There's no reason to keep doing expensive CPU operations if it's unnecessary. -Dan -Original Message- From: Jonathon Stierman [mailto:[EMAIL PROTECTED] Sent: Monday, December 17, 2007 10:58 PM To: CF-Talk Subject: memory issues An application of mine has recently been acting up -- memory has been shooting up at a fairly rapid pace this past week, and I'm at my wits end! Can't seem to find any way to fix it. Here's the symptoms: After rebooting the CF service, memory starts out at about 60mb for the jrun.exe process. After that all hell breaks loose ;) It continues to consume about 4 megs a minute until it plateau's at about 590mb. At that point, the server starts delivering 500 null errors, and my application/exception.log files fill up with java.lang.OutOfMemoryError messages. The site gets a couple hits a second, and those hits are fairly heavy in processing. Most involve file-reading and then parsing that file for the relevant data. I have downloaded a trial version of FusionReactor and got that set up on the system. If I'm reading it right, it looks like every request coming in is consuming large amounts of memory. I can understand why they'd take up lots of memory -- each one has to read a text file that is between 200k and 5 megs, and that seems to correlate with the memory jumps -- but why wouldn't that memory be released after the request is complete? It just keeps piling up. Is this to be expected from high volumes of file-reading/parsing requests? What advice can you give for getting some of that memory free and available? Server monitoring and tweaking is definitely not my forte -- any help and knowledge will be much appreciated! TIA! Oh -- incase the box info helps.

RE: Exclusive locks still producing duplicate values
cflock name=#session.st#ProcessLock timeout=20 type=exclusive I'm taking a bit of a guess here, but I think your name may be the problem. I'm assuming that by having a session variable in the name, each user will have a different name for the lock. Named locks are only locked from blocks with the same name. If each user is getting a unique name, then the block will not be locked between users. That is my understanding of locks at least. If this is the case, you want a single, discreet name for the lock so that all users use the same named lock and thus can only use the block of code one at a time, which I believe is your requirement. The fact that the lock is given a name based upon a session variable is definitely a problem--that only guarantees that the locked code won't run for sessions where the variable session.st is identical. I'm guessing that variable is unique per session. Also, just because you lock code calling the ReqNumbering.cfc component, the code in that component is not necessarily locked. That means if RegNumbering.cfc is called from other places outside of this locked code, it would run unlocked. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295018 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: memory issues
1. User logs in and requests a file. 2. Application reads file, and builds a Query object out of it. Every line of the file is saved to the Query. 3. A SELECT statement is performed on the Query to only get the relevant data for that user (cached for 30 minutes) 4. Results of SELECT shown to user The caching was added to speed up the processing on that page, but I'm wondering if it's causing my memory issues. Assuming the Query object is probably about the same size as the file the user reads, then I'd be caching the 200kb-5mb for every user. Sounds great for CPU/speed performance, but not so good for memory conservation. Am I off my rocker, or could this be the culprit? A query object of a text file I'm sure would use more memory than just the text file stored as a string. It also depends on how much of the cached queries contents you're keeping around (you indicated that your doing a QoQ and caching those results.) That caching could definitely be the cause of the problem. I'd recommend poking around your application and session scopes to see just how much data you're actually caching. Check out this post by Steve Brownlee: http://www.fusioncube.net/?p=66 The section labeled All ColdFusion Sessions shows you how can get to all the sessions on the server.

RE: memory issues
Jonathon, And while it definitely seems to slow down the memory consumption rate, it still doesn't appear to be freeing up any RAM. I did some test runs, loading some of the larger files. I saw the corresponding RAM increase, but never seeing that memory released. I plan on converting it all to being database-driven, but I'm still confused as to why this memory isn't being released. Are the Queries being eliminated, but not removed from memory just yet? Is there a way to force garbage collection while CF is running so that I could test this theory? Just because you're not using the memory, it doesn't mean that Java will free it up immediately. Since Garbage Collection is an expensive CPU operation, it tries to do the GC as infrequently as possible by default. You can think of Java and its Garbage Collection sort of like the Windows Recycling Bin. Just because you delete a file and put it in the Recycling Bin, it doesn't actually free up disk space right away. The file is in the Recycling Bin and still takes up disk space. Windows will eventually remove the files and reclaim the disk space when it needs to based upon your Recycling Bin settings. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:295060 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

The cfthread / version was always faster. Your environment is going to largely dictate what kind of advantages you see from threading tasks in your code. Also remember anytime you need to join the threads together, which would be the case here, your code is still going to have to wait for the slowest running thread. That means if you have a feed that on average takes 900ms to return its results, that's not a bottleneck threading your code will fix. The benefit really comes from when you have 4 processes that each takes 900ms to complete. You're going to have to wait at least 2800ms for that task to finish when run in serial. By threading the processes and running them in parallel, you'll drastically reduce the wait time since all of those tasks run at the same time. You could end up reducing the wait time by 2100ms. You'd really notice the benefits of threading the requests if you start running into network latency issues or issues with the server returning the results in timely manors. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294843 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: OT: Eclipse speed issue
Jake, Thanks for the suggestion. I changed my my heap to a min of 128 and a max of 512 in my eclipse.ini file. I'm not sure I really see a difference. I did, however, notice that Build Automatically was checked in the project settings. I unchecked that. I suspect that recompiling 25,000 lines of code over and over wasn't ever going to be very fast. That helps the speed issue a bit but I might still be missing something. If any more advanced Eclipse users have any suggestions, I'd love to hear them. My guess is it's just having problems parsing a file that big. Generally most Java classes are no where near that size and my guess is the parsers for syntax highlight and code hints are just taking a long time. As I've never worked on a Java class anywhere near that size, I'd recommend searching for answers on an Eclipse-based mailing list. I will say I have problems with CFM templates in CFEclipse that are more than a few 1,000 lines of code, but it seems to be related to CFEclipse (since I can open the templates in other views without the degradation in performance.) I'm pretty sure it's the parser in CFEclipse that's having problems parsing the template. I suspect if I turned off code hinting the problem would go away, but the problems I've seen could be related to the color parsing. Anyway, my guess is it's an issue with the parser for the Java perspective. There may be a workaround, but you're most likely to find solutions from people who work with the Java perspective almost exclusively. -Dan ~| Download the latest ColdFusion 8 utilities including Report Builder, plug-ins for Eclipse and Dreamweaver updates. http;//www.adobe.com/cfusion/entitlement/index.cfm?e=labs%5adobecf8%5Fbeta Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294586 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Encrypting/Decrypting XML
Scott, Is there a way to encrypt and decrypt XML on the fly. I'm building a small cms, and want to store the login information in an XML file. I need to be able to read An encrypted file, do the typical login/password check and leave the file encrypted on the server, to keep it away from prying eyes. You could just hash the password and then store it in clear text in the XML. -Dan ~| Enterprise web applications, build robust, secure scalable apps today - Try it now ColdFusion Today ColdFusion 8 beta - Build next generation apps Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294249 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Eclipse CFEclipse
Assuming you're an Eclipse/CFEclipse user, how would you respond to this question: Is Ecliple/CFEclipse overkill for an independent developer, who never has to worry about checking code in or out? I am having some trouble keeping my development versions of sites synced with my production versions. It can get quite crazy trying to keep up with what change are where. Which is exactly why you need source control. -Dan ~| Get the answers you are looking for on the ColdFusion Labs Forum direct from active programmers and developers. http://www.adobe.com/cfusion/webforums/forum/categories.cfm?forumid-72catid=648 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294145 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: AJAX Caching
Ric, I am building a little app in CF and using AJAX. (not CFAJAX) Basically it has 2 types of functions. The first returns a CF created table to display the data list. The second returns a CF created list, that I break up in javascript to populate my form. I am having an issue that all the data being returned is cached (in the browser, not server side). Any ideas on how I can stop it? Is appending a uuid to the query string my only option? I am using the no-cache meta tag param but im sure that is just for the front end html. How do I also stop the javascript from being cached? Without turning off caching in the browser. This part wont be an issue for production, but its annoying in development. Lots of solutions to this problem, but this method is one of the simplest to implement: http://www.ferdychristant.com/blog/archive/DOMM-6R8HL2 And don't forget that Google is your friend with these types of requests. A simple search for prevent ajax caching brings back lots of solutions. Also, if you don't want to go the JS route of adding a date stamp to the url, you can pass back response headers to prevent caching: http://www.greenash.net.au/posts/thoughts/an-ie-ajax-gotcha-page-caching (Take a look at the comments for the CF equivalent code.) -Dan ~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293993 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: CF8 and CFmail, sending duplicate emails
Will, We recently upgraded our server to CF8. We have a number of clients who use emailing tools to send out emails to opt in lists. One of these clients did a mailout last week to a couple of lists, and it would appear that the emails all went at least twice to every member of the list. The code has run perfectly on CF7 for a couple of years, so I'm pretty sure it's not a code issue. I wouldn't be so quick to dismiss a code problem. I've seen a lot of code in my time that once worked that stopped working on an upgrade. It could be the use of a depreciated function or tag, or simply code that worked due to issues in the CF engine at the time--but which shouldn't have run. Also, I believe I remember reading CF8 changed some behavior of nested cfoutput/cfloop tags in CF8, but I can't recall exactly what I read. Finally, I will say don't overlook the obvious. If a user clicks on a link/button multiple times, unless your script explicitly prevents the behavior, the server will process the request multiple times. This is the most common cause of duplicates that I've seen. -Dan ~| Get involved in the latest ColdFusion discussions, product development sharing, and articles on the Adobe Labs wiki. http://labs/adobe.com/wiki/index.php/ColdFusion_8 Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293863 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
RE: Updating to Eclipse 3.3...
from 3.2 to 3.3; I think you have to simpy install 3.3. Unfortunately, I don't know how to preserve or import settings. File, Export, General, Settings. My personal experience is it's just easier to rebuild. I've tried the export settings, but it's caused me problems in the past. I think the problem stems from the fact that so many plug-ins are completely re-written for different versions of Eclipse. The good news is you should be able to go to File Import Existing Projects into Workspace and it should import your project into your new build (although things like the local history won't be imported.) From there it's just a matter of installing the plug-ins you want. Maybe it's because I only use a handful of plug-ins (CFEclipse, Aptana, FileSync, Flex and the various Adobe Eclipse plug-ins,) but it usually only takes me 30 minutes or so to get all my plug-ins restored. Also, I definitely think v3.3 is worth upgrading to. Performance for me has been much, much better. -Dan ~| Enterprise web applications, build robust, secure scalable apps today - Try it now ColdFusion Today ColdFusion 8 beta - Build next generation apps Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293864 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
RE: Updating to Eclipse 3.3...
Andy, What settings are you talking about? Is there a single file, or a folder? Do I have to reinstall all my plugins as well? I'd recommend just extracting Eclipse v3.3 into a new folder and then re-installing the plug-ins (as I stated in another thread.) I think in the long run it'll make life for you smoother. Re-installing the plug-ins shouldn't take long. -Dan ~| Create robust enterprise, web RIAs.
