RE: STICKY Application.datasource
You can most certainly store the datasource in an application variable. Assuming you have a whole bunch of app vars that you will be using throughout your application. Andrew is correct in what he is saying about using request scope as you don't need to lock the application scope EVERY time you want to use it. Instead you can use something like:- cflock scope=APPLICATION type=READONLY timeout=10 throwontimeout=Yes cfset Request.Application = duplicate(Application) /cflock Martin Parry Macromedia Certified Developer http://www.BeetrootStreet.co.uk -Original Message- From: Andrew Grosset [mailto:[EMAIL PROTECTED] Sent: 29 December 2004 05:16 To: CF-Talk Subject: Re: STICKY Application.datasource Unless it's really necessary I would try not to set datasource as an application variable, either: cfset datasource=CODAGenomics or cfset request.datasource=CODAGenomics Andrew. ~| Special thanks to the CF Community Suite Silver Sponsor - CFDynamics http://www.cfdynamics.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188919 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54
RE: shopping cart, session variables - best practices
I personally favour client variables. But bear in mind that you must be using a proper DB server, NOT access for this to work. SQL, MYSQl Etc. Additionally, in CF admin the client variables must be purged in a reasonable time if SQL disk space is in short supply or you get a billion hits a day. Use a structure for storing the basket contents by all means, however instead of session.basketContents, convert the structure to a WDDX object and store it as client.basketContents - That way you're not using precious RAM but cheap disk space.

Yes, but... Be aware of single argument methods: I seem to recall that if Flash sees obj.method(singleArg) and singleArg is a struct, it treats it much like CF's argumentCollection and passes the elements of the struct as separate arguments I think. It's a special case with single argument methods. Okay, then this leads me to my next question. Do I need to change my CFC if I know down the line I'd like to use it with Flash Remoting?

RE: My Init() in my CFC...am I on the right track?
Personally I really hate the notion of chaining setter calls (but I can see way others may like it). I do find that much harder to read. But other chaining is great. Being able to chain the create and the init() together seems perfectly sound to me. As does any call which returns a CFC as a property then calls a property of that return as in something like this: cfset Name = Session.SessionCFC.getUserCFC().getName() / I agree. I was only referring to setter methods (though I may not have been very clear about that). In the above example, you're using getters. A getter's purpose is to return something. Conseqently, the purpose of the line above seems very clear to me. This is in contrast to an example posted by Sean in another thread: person.setFirstName(Sean).setLastName(Corfield) I find it more difficult to read. I would be very surprised if it were any faster than two lines of code. So, I was wondering if there were any other benefits or tricks that I'm missing.

RE: Question for Java people on this list: Converting a CF app to JS P
I forgot to paste it in:
String dept = rset.getString(DEPARTMENT); from my Oracle Query
switch(dept) {
case FAO:
out.println(It\'s FAO.);
break;
case CAO:
out.println(It\'s CAO.);
break;
case RES:
out.println(It\'s RES.);
break;
default:
out.println(It is a different one.);
}
This is my first try at Java/JSP so this is only an example that I am trying
to get working before I add the real logic to it. I figured out the query and
the result set and looping over the result set -- sorry nothing beats CFQUERY
but this SWITCH statement is confusing me.

RE: Question for Java people on this list: Converting a CF app to JS P
Java doesn't allow you to use anything other than integer (or castable
to integer) values for switch statements, so strings can't be sued.
With a switch that small, I recommend a series of if statements
String s=department.trim().toUpperCase();
if (s.equals(FAO)) rate=0.09;
else if (s.equals(CAO)) rate=0.19;
else if (s.equals(RES)) rate=0.39;
else rate=0.09;
This will do at most 3 string comparisons, which isn't all that bad.
Assuming you are just mapping values to values, you might want to use a
map/hashtable/properties object...
Example:
// scope this in the application scope
java.util.Hashtable values=new java.util.Hashtable();
values.put(CAO,new Double(0.19));
values.put(RES,new Double(0.39));
values.put(DEFAULT,new Double(0.09));
Then you can do Double d=(Double)
values.get(department.trim().toUpperCase()) to get the value.
This is usually better for larger cases, where lots of if statements
would take longer than a single hash lookup
Then there's an alternative way to use switches if you have more code
than just an assignment to make.
First convert all your string values to integers via a map, and switch
on the integers
I would do this (so it's easy to read, like this)
Static final int FAO=1, CAO=2, RES=3;
Hashtable table=new Hashtable();
Table.put(FAO,new Integer(FAO));
Table.put(CAO,new Integer(CAO));
Table.put(RES,new Integer(RES));
int switchValue=-1;
Integer d=(Integer ) table.get(department.trim().toUpperCase())
if (d!=null) swtichValue=d.intValue();
switch(switchValue){
case FAO:
...
break;
...
etc...
}

No, I agree first! ;^) I've heard one argument with setters in that it might allow for more structured sets of complex data to be read more easily. For example if you have a form accepting first, middle and last names you could say: person.setFirstName(Sean).setMiddleName(Elizabeth).setLastName(Corfield ) (I am, however, guessing on the actual middle name in this case.) In this case I can see the argument that when you put on syntax blinders you see the name of the person as it should be seen. However I agree that the following seems much more readable: person.setFirstName(Sean) person.setMiddleName(Elizabeth) person.setLastName(Corfield) The other argument I've read is when you use a setter for an object, then immediately grab something from that object. Something like: profile.setPerson(Sean).getFirstName() I see this as a little more useful than the first argument (which to me is really simplistic and should be multiple lines). At the same time cases like this seem pretty rare to me. I've also heard (what I consider completely asinine) arguments that smaller code is better or runs faster or whatever. This of course is complete bullshit (it was bullshit even in the old CF days when the language was tokenized and is even moreso now in the compiled Java world). Still - returning this in a setter doesn't force you use this, it just provides the potential.

Re: STICKY Application.datasource
Since the advent of CFMX 6.1, the Macromedia specs state (no time to
find a URL, it's moving day 3) that shared-scope variables that will
be set once and contain a static value (i.e. static data available to
the entire app... like a DSN) do not need to be locked. Race
conditions and deadlocks were eliminated, so the only reason to use a
lock is to prevent data corruption... as long as your DSN isn't going
to change there isn't a reason to lock it.
At least according (I believe this is where it is) the LiveDoc for the
cflock tag under 6.1.
Also, even tho I'm sure this has already been stated, setting an
application variable in a cfparam tag is a fine idea, but changing the
default isn't going to change the value until you've deleted the
original... because application variables are persistent, and because
the cfparam tag doesn't fire to create the var unless it doesn't
already exists, the only way to change the value is either to delete
it... or, something I've done often is to put a cfif in
application.cfm that looks for a URL variable to fire off some CFSETs:
cfif isDefined(URL.reloadAppScope)
cflock scope=application type=exclusive timeout=20
cfset application.appVar1 = 1
{more cfset tags to write your app vars}
/cflock
/cfif
And that's my own two cents...
Laterz,
J

I'm reading all of this conversation as the former (the first one) meaning that if you WANT to be able to chain a method, that method needs to return this. If you want to chain method calls on the same object, all of the methods in question must return this: person.setFirstName(Sean).setLastName(Corfield) In this example, you have a person component with methods setFirstName and setLastName. Each of those methods is returning this. The long way to accomplish the above is: person.setFirstName(Sean) person.setLastName(Corfield) In the other example posted, multiple CFCs are involved: Name = Session.SessionCFC.getUserCFC().getName() In this example, the getUserCFC() method belongs to the SessionCFC component. It is returning a UserCFC component, not this. The getName() method belongs to the UserCFC component, not the SessionCFC component. The longer way to accomplish the above would be: User = Session.SessionCFC.getUserCFC() Name = User.getName() Ben Rogers http://www.c4.net v.508.240.0051 f.508.240.0057 ~| Special thanks to the CF Community Suite Silver Sponsor - CFDynamics http://www.cfdynamics.com Message: http://www.houseoffusion.com/lists.cfm/link=i:4:188937 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4 Donations Support: http://www.houseoffusion.com/tiny.cfm/54

RE: STICKY Application.datasource
Assuming you have a whole bunch of app vars that you will be using throughout your application. Andrew is correct in what he is saying about using request scope as you don't need to lock the application scope EVERY time you want to use it. Instead you can use something like:- cflock scope=APPLICATION type=READONLY timeout=10 throwontimeout=Yes cfset Request.Application = duplicate(Application) /cflock While you can do this, in my experience this causes a terrible performance degradation in applications with moderate or heavy use.

RE: shopping cart, session variables - best practices
Use a structure for storing the basket contents by all means, however instead of session.basketContents, convert the structure to a WDDX object and store it as client.basketContents - That way you're not using precious RAM but cheap disk space. Storing application- and user-specific data is what precious RAM is for! In an application environment with a single application server, you will typically achieve significantly higher performance under load by storing things in memory rather than fetching them from the database for each page request. You may need to provision your server's RAM adequately to ensure you have enough for the number of concurrent users you need to support, but RAM is comparatively cheap.

RE: STICKY Application.datasource
Unless it's really necessary I would try not to set datasource as an application variable, either: cfset datasource=CODAGenomics or cfset request.datasource=CODAGenomics In general, I agree with this. If the value of a variable won't change during the operation of an application and the variable contains a simple value, there's little value in storing it persistently beyond a single page request, since there's very little cost involved in simply recreating it on every page request as needed. However, if you're using CFMX it really doesn't make any significant difference one way or the other, and even with previous versions it usually didn't as long as you were careful to create the variable once but never write to it again.

RE: shopping cart, session variables - best practices
Any reason you're not using an array of structs? It would be much cleaner to work with and much faster than using lists (which is going to have much more impact on your performance than storing data). While I agree with your suggestion to use arrays and structures rather than lists, I doubt it would have a fraction of the impact on performance that choices about storing data will have. You might save a few milliseconds per page by avoiding lists, but you will typically suffer a more severe performance penalty by making trips to the database instead of storing things in the Session scope in my experience.

RE: Setting Default Printer
Does anyone know how to set a default printer from a list of prints shown in a webpage? im using the tag CFX_EnumPrinters to enumerate the printers, but im not sure how to allow the user to pick the default. Are you trying to set a default printer on the server or on the client? Presumably, your CFX custom tag lists printers on the server, not the client. You could run the VBScript code you posted from a command shell using CFEXECUTE, or adapt the code somewhat to make it available as a WSH COM object, although I've had limited success in using Windows Script from CFMX to control printers and would try to avoid doing that if I could. Instead, you could simply track the printer choice that the user made and force server print jobs to use that printer within your own code. Finally, keep in mind that the server will only be able to have one default printer, so if one user changes it to printer A and another changes it to printer B, someone's going to be disappointed.

Re: large cf ecom sites?
Half.com uses some CF and they're pretty big too... Tek-tips.com is entirely CF driven and has nearly a million members and probably 4 constantly active. The simplest way to say it to the client is that the security and stability of the application is as much about the programmer's skill as it is the language programmed in and that his marketing guy may have had bad experience with a cf application, but like any product, internet or physical, the craftsmanship is the key. An Emerson TV offers as much as a Sony sometimes, but Sony is higher quality and therefore lasts longer and is better but they are both built on the same technology.

RE: My Init() in my CFC...am I on the right track?
Good lord this is a lot of...ahem...stuff to remember... Fortunately, you don't really need to memorize it all as if it were a multiplication table. You just need to think about how objects, methods and properties work. For example, if you want to chain methods, you can see how things work within equivalent code that doesn't chain methods. Let's say you have an object foo with methods bar and baz. It doesn't matter what those methods do, just how you'd write the code to call them. cfset myfoo = CreateObject(component, foo) cfset myfoo.bar() cfset myfoo.baz() In the above code, we're creating an object instance called myfoo, then calling the bar and baz methods, each on a single line. On the second two lines, we're not doing anything to catch the returned value from each method call, so presumably it doesn't matter what values are returned by each method. On the other hand, let's say we want to be able to chain these methods together: cfset myfoo = CreateObject(component, foo).bar().baz() We already know that the CreateObject call returns an instance of foo, which contains a method bar so we can call that. To be able to call the baz method within the chain, we can see that bar needs to return the same object instance. Where's a good reference for ALL of this conceptual stuff? Not the syntax, or what you can and can't write...but general conceptual here's what you're trying to accomplish by using CFCs and here's why you want to do some of the things you want to do sort of document? I've seen ALL sorts of here's how to invoke a CFC and here's how to write your first CFC but nothing on, so you want to design a good, robust CFC?...what's a good reference that's syntax independent? Any primer on object-oriented programming, or any book introducing an object-oriented programming language such as Java, will do for this sort of thing. I don't know of anything that's CF-specific other than Hal Helms' book on components, which is a bit problematic in that it spends quite a bit of effort showing how to avoid problems that are specific to CFMX 6.0 if I recall correctly.

RE: Setting Default Printer
Im trying to do this on the client. I want to present them with a list of their printers and have them select which one they want as a default. Well, to be perfectly honest, I think this is a bad thing to do from within a web page. The user's computer has perfectly good mechanisms to do this already. If you simply use JavaScript to open the standard printer dialog from within your application, the user will be able to print your web page just like she'd print from any other application. If you still wish to continue, you could presumably do what you want by placing that VBScript within your page to run on the client. You will not be able to do this purely with server-side code.

I think we should really find out the capabilities of Mayo's server/host before we can truly suggest one method over another. I wouldn't go so far as to say I was suggesting one mechanism over another. I merely pointed out that, in general, you improve the performance of web applications by storing data in application server memory instead of fetching it from the database for each page request. In high traffic eComm sites I have seen superb performance using the method described. There are plenty of reasons why you might choose Client variables or other database storage over Session variables. It is certainly possible to build applications that perform acceptably well using any of these approaches. My point was simply that storing data in memory will perform better than storing it in a database, all other things being equal.

We already know that the CreateObject call returns an instance of foo, which contains a method bar so we can call that.

FB4 prefuseaction postfuseaction hang server
I'm sure I'm missing something simple here, but I can't seem to figure it out although I have found a work around. I currently have one circuit named admin that I'm using. Below is the circuit.xml file: circuit access=public prefuseaction /prefuseaction fuseaction name=list do action=admin.header / include template=qry/qry_GetFileList / xfa name = deleteAction value = delete / xfa name = searchAction value = list / include template=dsp/dsp_fileList / do action=admin.footer / /fuseaction fuseaction name=delete do action=admin.header / include template=dsp/thisFar / do action=admin.footer / /fuseaction fuseaction name=header include template=dsp/dsp_pageHeader / /fuseaction fuseaction name=footer include template=dsp/dsp_pageFooter / /fuseaction postfuseaction /postfuseaction /circuit I can run this just fine in my application, no problems. Now if I take the do action=admin.footer / for example out of the fuseaction list and delete and put it under the postfuseaction and then view the list or delete fuseaction, my server hangs as it's eating up the CPU (goes on longer then 2 minutes before I restart the server). Bottom line is, do action works in individual fuseaction list or delete but not when it's in the prefuseaction or postfuseaction areas.

Are you sure you aren't creating an endless loop by running something in the prefuseaction that, when it runs, tries to run a prefuseaction again, and again, etc? Hope that helps.

Re: cfapplication/clientvariable Error after Upgrade to MX 6.1
Long shots, but since the error is in your cfapplication tag I would go into the administrator and make sure both application and session variables are enabled (Server settings Memory Variables). If that doesn't work, you might also try clearing the cookies out of your web-browser. It's another long shot, but if you still have CFID/CFTOKEN pairs in there from CF5, it could mess you up, esp if you went from using UUID for cftoken to not, or vice versa. -Cameron On Wed, 29 Dec 2004 16:10:12 -0600, Dave Phillips [EMAIL PROTECTED] wrote: Hi all, I just upgraded to MX 6.1 and now I'm getting this error: The system has attempted to use an undefined value, which usually indicates a programming error, either in your code or some system code.

RE: shopping cart, session variables - best practices
In high traffic eComm sites I have seen superb performance using the method described. There are plenty of reasons why you might choose Client variables or other database storage over Session variables. To expand on Dave's statement the times you would want Client variables over memory (session) variables for storage is when the application needs to operate in a cluster of web servers. Sharing memory (session) variables then become impracticable. My point was simply that storing data in memory will perform better than storing it in a database, all other things being equal.

You can either use session replication or you can use sticky session - both allow session variables to be used effectively with clusters. macromeda.com is a cluster of several CFMX 6.1 instances, with hardware load balancing and lots of session data. We use sticky session in the load balancer. -- Sean A Corfield -- http://www.corfield.org/ Team Fusebox -- http://www.fusebox.org/ Breeze Me! -- http://www.corfield.org/breezeme Got Gmail? -- I have 6 invites to give away!

You're creating an infinite loop. If your postfuseaction is admin.footer, that will go to circuit admin (this one) and run footer followed by postfuseaction... which will try to run admin.footer again. You'll need a separate circuit containing the header / footer stuff so that your admin circuit can do those actions.

RE: shopping cart, session variables - best practices
To expand on Dave's statement the times you would want Client variables over memory (session) variables for storage is when the application needs to operate in a cluster of web servers. Sharing memory (session) variables then become impracticable. Session state stored in client variables also survive service and server restarts. Even though he actually did, it just goes without saying: memory is faster than I/O. Under a heavy load, this is no doubt true. However, I was recently surprised to find that under a small to moderate load, there may be no noticeable performance difference. I was recently tasked with upgrading a site from ColdFusion 5 to MX. I had used client variables when originally designing the site for various reasons. Mostly, I was trying to avoid locking issues and anticipating the need for clustering. Suffice it to say, we never had to cluster the site and locking for stability's sake is no longer necessary. So, when performing the upgrade, I decided to test the performance difference between using session variables and client variables. It took me a couple of hours to update the code base (20,000 lines of code). I was surprised to find that, under a minimal to moderate load, I could not measure the performance difference using the tools I had. Consequently, I decided not to make the switch (don't fix what ain't broke). That said, for new sites, I generally use the session scope because I can store complex objects such as CFCs in the session scope. Additionally, since the session scope is now thread safe, I don't have to worry about whether or not every developer is properly locking their code.

cfmail and exchange server
The operations side of the house has recently built a windows 2000 server with exchange server 2000. Its an outsourced box at a server farm in Texas (good place for a farm). I've written a simple piece of code that creates a maillist with my email address 1,000 times. cfset maillist = cfoutput cfloop condition=counter lt 1000 cfif listlen(maillist) cfset maillist = maillist , [EMAIL PROTECTED] cfset counter = counter +1 cfelse cfset maillist = [EMAIL PROTECTED] cfset counter = counter +1 /cfif /cfloop /cfoutput I then use cfmail to loop over the list and send me 1,000 messages. cfoutput cfloop list=#maillist# index=i cfmail to=#i# from= [EMAIL PROTECTED] subject=#getMessages.Subject# type=html server=MyExchangeServer p#getMessages.Title#/p #getMessages.Content# /cfmail The CF page runs in about 13 seconds. It then takes the exchange server about 17 minutes to send off the 1,000 messages. That's only 3529 messages an hour. There is no way in hell a spam house can be profitable sending out 3500 messages and hour. I get offers to send out 1 million emails for $150.00 all the time. At 3,500 an hour that would take over 285 hours (nearly 12 days). Something has got to be wrong. Note: I am not bulding this to send out spam. We are trying to send out a newsletter type email to 25,000 opt in users. Anyone got any ideas? Being the CF runs in 13 seconds I doubt it is on the cf side. Anyone familar with Windows Exchange server?

Re: Thread-safe CFCs
Yes.A long post will ALWAYS go through. The warning (which will be lengthened to 150 lines) is to remind people to trim their posts. In addition, the first post on a thread is always unlimited. I think the mail you got saying your post was to long is just a warning, it still goes through. Is this right Mike?
