RE: Can I ask a question? (RE: Frameworks)
and wherever you get your job programming, you'll learn that they probably have procedures in place that you'll have to learn in order to work well with the team that you'll join. I guess that was our framework discussion. I think this all depends on what you are attempting to do, as each framework is intended to solve a (sometimes different) set of problems. In your environment Jeff, the problems that each framework addresses may not be relevant. Each framework is targeted at a specific problem, take for example ColdSpring; Do you program in an OO fashion and have many dependencies between your objects? Then ColdSpring is a framework that can help you manage those dependencies in an easy way (not to mention AOP). Do you have code that is tied really tightly with your display pages, causing all sorts of headaches when you need to update something? You might want to look at an MVC framework. In the end, many of the concepts that are applied are done so to help reduce the effort it will take to maintain the application. These things may or may not apply to your situation. If you run into these problems, then you'll become an advocate of frameworks, and the people that craft them.

RE: Testing Database Connection within Application
There is a decent chance that the admin api functionality gives you
access to the same thing that happens when you click the verify data
source icon in CF Admin.
Yes, you can get this from the adminapi:
cfscript
// you must log in before accessing other adminapi components
adminObj = createObject('component',
'cfide.adminapi.administrator');
adminObj.login('yourCFAdminPassword');
// create the data object and test the DSN
dataObj = createObject('component',
'cfide.adminapi.datasource');
writeOutput(dataObj.verifyDSN('dsnName')); //returns boolean
/cfscript
I tested shutting down my datasource, and it retured false in about 1-2
seconds in my local environment.

RE: Access my SessionService from Gateway (MG, CS, Reactor)
From your description, it seems like you are mixing layers (which will
IMO bite you later). I would suggest keeping your components as focused
as possible. When working on this type of problem, I create services
that manage each of the entities in the domain. I generally separate
user authentication from authorization / entitlement.
Here is some pseudo-code to demonstrate what I'm talking about:
UserService
- userGateway (table gateway e.g. sets of data)
- userDAO (manage single object persistence)
getUser(username,password) : UserBean ( userDAO.read(UserBean)
);
saveUser(UserBean) : Void ( userDAO.save(UserBean) )
getAll() : Query ( userGateway.getAll() )
UserDAO
read(UserBean) : UserBean
save(UserBean) : Void
UserGateway
getAll() {
select ... from ...
return query;
}
AuthenticationService
- UserService (access to the user)
- SessionFacade (access to the session)
processLogin(username,password) : Boolean {
user = UserService.getUser(username,password);
return authenticateUser(user);
}
authenticateUser(UserBean) {
log in user.
if (loggedIn ) {
sessionFacade.setUser(UserBean);
}
return UserBean;
}
EntitlementService
- UserService
- SessionFacade
getEntitlements(UserBean)
...
In this type of a setup, you could create accessors
(setUserFacade/getUserFacade) for each of the composited items and let
CS inject them.

I now need access to this session service from one of the Gateways. CS won't be able to autowire your model, but it can still wire those cfcs for you. In your services.xml file, define your façade and then define your gateway with the façade as a property like: bean id=yourGateway class=path.to.your.gateway property name=sessionFacaderef bean=sessionFacade //property /bean bean id=sessionFacade class=path.to.sessionFacade / Then when you ask CS for your gateway, it will have the session façade wired in.

RE: Access my SessionService from Gateway (MG, CS, Reactor)
I'm not using CS to access my gateway using the getBean() method, I'm accessing the gateway using something like this. LOCAL.gCredentials = getModelGlue().getOrmService().createGateway(Credentials); With that call you are talking to reactor I'm assuming. I've not worked with MG:U, so I'm not exactly sure what is going on in the construction of those objects. I know that MG:U provides scaffolding, and am assuming that the getOrmService().createGateway() call is referencing a table called Credentials that it read from your database. In this case, reactor is creating the gateway, not CS, so you have to determine how to inject the sessionFacade into the reactor generated file. I know that reactor generates files that you can provide custom methods, and that might be the place to achieve what you are trying to do. It could be that CS fires after reactor, so you might be able to add a reference in the reactor generated abstract gateway and have CS inject your façade. I'm sorry I can't be of more help with this exact issue, but I think that there is a list dedicated to MG:U, and you might find more help from people there. I'm a little unclear on what you are trying to achieve. Once you create the credentials gateway, it seems as though you are going to look up a users credentials.

RE: date compare
Firstly, what you have to keep in mind is that you said you have date/time fields. When you are trying: WHERE myDate = '03/26/2007' what you are really saying is: WHERE myDate = '2007-03-26 00:00:00.000' This comparison will fail on a record such as '2007-03-26 17:56:22.000'.

RE: You think you know OOP.. but you don't
I agree with most of your post, Dave. But one thing that bothers me about the 100 CF frameworks out there is that often times these guys make up their own dialect instead of trying to use existing terms that mean the same thing. I'm not a frameworks expert, but from the reading I've done, Fusebox and Model Glue each introduce new terms for concepts that have been around for a long time (for example, fuse and all of its variants). I really wish people would stop trying to be cool, and just use existing standard language. I have to disagree to an extent. Of all the frameworks in CF that I have seen, each attempts to leverage methodologies proven in other languages and bring them to CF (MVC, ORM, etc.). Inside each framework, each attempts to communicate the moving bits as best they can as there is not always a 1-1 relationship with other languages. For example, in many event driven applications you either broadcast an 'event' or broadcast a 'message'. In both MG and MII, the exact names change, but the intent is carried through. Learning CF has nothing to do with learning a framework. Leveraging a framework or a design pattern helps developers solve specific problems they encounter. Too much business logic tied to your display? Use the MVC pattern (and perhaps a MVC framework). How someone learns CF is based on a myriad of factors and varies greatly from person to person. Each of these Buzz words solves REAL problems that developers face day to day. The Buzz words are buzz words in CF, but have long since become standard practice in most modern languages.

RE: A quick referance guide to OOP MVC
I'm looking for someone to give me a rough rundown of some of the OOP terms that I keep seeing thrown around and yet still baffle me. I've got some elements of my application that I've been handed by other people, and they refer to them as 'Facades' or 'Utilities' or 'Services' what are the definitions of those? And how should they be applied within an application. Facades: A Façade is intended to keep your code from knowing how something is managed. In web based OO, you often need to persist a user object across the life of the session. You would not want session references sprinkled throughout your code, so you create a UserFacade. Your application asks the façade for a user, and the façade manages persistence of the user object in the session scope. Services: Services are often referenced as part of a SoA (Service oriented architecture). The easiest way I can describe them is using an analogy ;) Think of the process of going to the bank. You walk up to a teller, hand him/her your account number and tell them what you want to do. For example, I tell the teller my account number is 101 and I wish to deposit 500 into my checking account. The teller hands me a receipt and tells me the money has been deposited. You have no knowledge of exactly what the teller DID, you just know that the money was deposited. The teller performed a service to you. The teller can perform many other services like withdraw money, transfer money. Other services offered in the bank are home loans, but they are offered by a DIFFERENT person (think object here). So the idea is that each object has a set of services that it offers. Those services might depend on a number of different objects in your business model, but the service hides the inner workings and just exposes the facts that it needs to perform the service. The tellerService might depend on an authentication object to verify that I have an account, an account object to deposit the money, etc. The method call tellerService.depositMoney(accountNumber, amount) is all the rest of the application has to see, and simply depends on the return (like a receipt) to know that the deposit was successful, so you hide many of the dependencies. This makes for a stronger application. Transfer Objects (TOs): Transfer objects are simply objects that contain only data. They expose this data as properties. See http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html for a full explanation. I'd be interested to take any recommendations on more general perhaps java based OOP, MVC and AOP related books that would be worth me reading. Many of the things you are reading / hearing are in reference to Design Patterns (gateways = table gateway pattern, DAO = Data Access Object Pattern, etc). It might make things clearer if you look into the GoF (Gang Of Four) and their book Design Patterns: Elements of Reusable Object-Oriented Software. I highly recommend Head First Design Patterns (http://www.amazon.com/Head-First-Design-Patterns/dp/0596007124), it's in Java but relatively easy to follow and an amazing explanation of many different patterns.

RE: A quick referance guide to OOP MVC
But what's this with TO's being an object only containing properties? I thought that was a bean? So for instants I'd have a bean that containing only getters and setters, nothing more, is that a TO, or is a TO more like an active record that represents a row of table data? Rob, It's just a really lightweight version of an object that can be passed around. It can also be used in the memento pattern (using a TO to populate a bean). For example: cfcomponent displayname=userTO cfscript THIS.id = 0; THIS.firstname = ''; THIS.lastname = ''; THIS.password = ''; THIS.emailaddress = ''; /cfscript /cfcomponent This TO would then be handed to another object, for example a DAO: cffunction name=Save cfargument name=to type=path.to.TO / cfset var qSave = / cfquery name=qSave datasource=#getDSN()# UPDATE users SET id = #arguments.TO.id# ,name = '#arguments.TO.name#' !--- etc... --- !--- and use CFQUERYPARAM! --- /cfquery /cffunction HTH Rich Kroll ~| ColdFusion MX7 and Flex 2 Build sales marketing dashboard RIAâs for your business.

RE: SVN Dreamweaver
I believe the way you are using VSS is using the lock-modify-unlock model for source control. Subversion uses a different model, the copy-modify-merge model. We used VSS prior to moving to SVN, and some of the decision makers had concerns with switching to a model where multiple developers had the ability to modify the same code. Since we have moved to SVN and embraced its model, we have seen dramatic increases in productivity as well as code stability. We have over 15,000,000 lines of code in our application, and the only times conflicts occur is when people are working on the same area of the application and making conflicting changes (which usually means a lack of communication somewhere). If you are set on attempting to use the lock-modify-unlock model, you can access information on it at http://svnbook.red-bean.com/en/1.2/svn.advanced.locking.html (though I *highly* recommend NOT using that model). We have a quite a few developers on our team that choose to use Dreamweaver as their IDE. There are a few software solutions that allow direct SVN manipulation from within DW, but are all purchased components. Instead of using these 3rd party components, we have all developers (not using Eclipse) to use TortoiseSVN and use windows explorer integration to perform all SVN operations.

RE: Nesting CFCs?
Scott,
There are two answers to your question. You can call methods in other
CFCs in two ways. The first way is through Inheritance, take the
following example:
cfcomponent displayname=ObjectA
cffunction name=aFunction
cfreturn A /
/cffunction
/cfcomponent
cfcomponent displayname=ObjectB extends=ObjectA
cffunction name=bFunction
cfreturn B /
/cffunction
/cfcomponent
Based on this example you could call ObjectB.aFunction() and it would
return A.
The other method for this is through composition. A quick example of
how this would work is:
cfcomponent displayname=ObjectB
cfset variables.objectA = createObject('component',
'ObjectA').init() /
cffunction name=bFunction
cfreturn B /
/cffunction
cffunction name=aFunction
cfreturn variables.objectA.aFunction() /
/cffunction
/cfcomponent
In this example, Object B contains a copy of Object A and when
ObjectB.aFunction() is called, it simply passes that call on to its copy
of objectA.
HTH,
Rich Kroll

Quick question - can you call one CFC from within another CFC? And if

In my case, I'd like to just have another cffunction block in the

RE: why Named Virtual Hosts in apache??
Virtual Hosts in Apache? On a development machine why do this? I use named virtual hosts on dev machine. I've got them set up to allow me to have a development 'playground'. For example when I start a new experimental project, I create a new directory and a matching virtual host in apache. For example I am working on a new OO project using Mach-ii, ColdSpring and Reactor. I created a new directory containing all three frameworks and my default folder / package layout. This setup allows me to work from the web root without having to move / delete anything existing in my standard webroot.

RE: DAO, Gateway Access
Robert, The 'traditional' way in which DAO's and gateways are implemented are that a DAO works with an individual bean and manages its persistence. A gateway manages retrieving sets of data, usually returned as a query. From what it should like you are doing, you are asking the gateway for a set of data, and then you want to message that data prior to returning it to the client. I would move the processing into a service object, which would contain an instance of your Gateway. Your method would proxy calls to the gateway, and then process the returned results.

RE: Switching to Weblogic 9.2 on Java 1.5 - which version of CF to use?
So that's where i'm at for now: 1) Might work with cfmx 7, but not supported. 2) Will most likely work with CFMX 8, but no information of whether it will be officially supported (the Weblogic 9.2 bit, not the java 1.5 bit). 3) Some kind of one time automated migration to regular java web app code. From everything that I've heard, your assessment is right on the money. The one time migration sounds a bit like snake oil to me as well, but it would be theoretically possible but IMO improbable.

RE: ColdSpring - What's my DAO do?
Rich, so based on this, it means I should have a dogFactory for my dogGateway as well as my dogDAO, right? Nope, you would have a single dogFactory to handle creation of dog objects. In its simplest form, the dogFactory would simply return a newly created dog instance. When inside your DAO, you would have CS inject the dogFactory. Here is an example read method for the dogDAO (assuming a getter/setter for the dogFactory and that it is injected): cffunction name=read access=public returntype=path.to.dog cfargument name=dogID required=true type=numeric / cfset var qRead = / cfset var dog = / cfquery name=qRead datasource=#dsn# SELECT id, breed, weight FROMdogTable WHERE dogID = cfqueryparam value=#arguments.dogID# cfsqltype=cf_sql_integer null=false / /cfquery !--- ACCESS FACTORY HERE --- cfset dog = getDogFactory().getDog().init() / cfif qRead.recordcount cfset dog.setID(qRead.id) / cfset dog.setBreed(qRead.breed) / cfset dog.setWeight(qRead.weight) / /cfif cfreturn dog / /cffunction Does that make things clearer?

RE: ColdSpring - What's my DAO do?
So - how do I create an object (or multiple) from within my DAO and DG without hard coding the path? After writing an almost complete example of how to set this up I realized that I missed the point of your question. You are referring to where you get a dog bean once inside your DAO / Gateway, and I first thought you were asking how to inject your DAO / Gateway into your service. So with that said, I think you are close in what you are thinking, but I would leverage ColdSpring to inject the factory into the DAO / Gateway. Your CS config would look something like: bean id=dogService class=path.to.service property name=dogDAO ref bean=dogDAO/ /property property name=dogGateway ref bean=dogGateway/ /property /bean bean id=dogDAO class=path.to.DAO property name=dogFactory ref bean=dogFactory/ /property /bean Then you only have one factory creating dog instances and it can be reused in both your DAO and Gateway.

RE: Uploading files to one server, propgating them to many. Was: Client variables? reliable enough?
My company currently has multiple load balanced web servers. Each time we deploy code, we have to manually FTP it to each server. We'd love to be able to upload (or SVN) code to one location and have an automated process to replicate the code to the other servers. We currently have a similar setup and are looking to use SVN to automate this portion of our process. We're currently looking to use a bat file to SVN Update / Checkout the code on the remote servers. We have an integration server where we currently checkout our repository to then copy the code to the remote servers. We are trying to do away with this method as we are using a large amount of bandwidth that is not really necessary. Using the SVN update / Checkout method, only the files that are needed will be transmitted to the production servers, or at least that is our thought. Is there something we're missing with this method?

RE: Take a minute to Digg this story about the Smith Project
Of course it would be quite awhile before smith was anywhere near the quality of Macromedia's product. By taking the project open source, I think they would enable more rapid feature development. The quality I think would depend on who is running the project and how many quality contributions from the community that were received.

RE: Daily procedures for using Subversion
You said that you thought of putting the entire web root under source control. Is the web root one project, or do you have multiple applications running under it? If it is one project then can create a repository where the trunk would be your entire web root. The repository structure would look like: |- Repository root |-trunk |-tags |-branches The problem with this approach is what happens if a new application needs to be put under source control? You end up with a very strange repo tree. I suggest creating your repository like: |-Repository root |-app1 |-trunk |-etc. |-app2 |-trunk |-etc. I would not worry too much about the revision numbers and how they increment with each committed change. They are there to enable you to isolate each atomic commit that took place. In terms of deployment and matching how you currently work, you could simple have your production server be a 'check-out' of the appropriate repository. You could also integrate ANT into your process and have build scripts automatically deploy your application. Also, how often do you commit a change to the repo? And last, how do you work when you need to get something out of the repo to work with? Do you download it to your local machine, or download to a test server? You can simply check-out a projects trunk into a local folder. When changes were needed, you would update your local environment (SVN Update), do the work needed, test, and then commit your changes. Suggested best practice is to create a tag or branch when you are ready to deploy, and simply deploy that tag/branch to your production servers.

RE: thread-saftey of application-instantiated components
There is the possibility for race conditions, so it depends what your component is doing. If your component has the following method: cffunction name=performMath cfargument name=num1 type=numeric required=true / cfargument name=num2 type=numeric required=true / cfset var result = (num1 * 2) + num2 / cfreturn result / /cffunction This method in an application scoped component is thread safe. There is no instance data that could change for each request. But this method is not thread safe: cffunction name=performMath cfset var result = (variables.num1 * 2) + variables.num2/ cfreturn result / /cffunction Thread safety becomes an issue when you are dealing with instance data within the component (the variables scope) that could change based on the actions of a different request. In cases like this you would need to lock the transaction just as you would any other shared scope variable.

RE: cfif vs cfswitch
I agree with Jochem's suggestion of using cfswitch for numeric or perhaps single character searches. The problem as noted in the link Jochem provided is that when using cfswitch, CF under the hood attempts a toDouble(), which if it is numeric hums happily along. If you pass in any type of string (including single character searches), CF internally throws an error which it catches and then attempts to re-process the cfswitch as a string. When a cfswitch is put in a loop (including queries) and uses strings is when this problem becomes more apparent. On an application with moderate load this could be the cause of performance problems. If the weight of all decisions is equally probably, you could argue the useage of cfswitch. I disagree. Based on the way the CF calculates a cfswitch, if you are within a loop and using a string for your case elements, there is no question IMO but to refactor the code to use cfif / cfelseif. Jochem also has a very good answer to this solution. Why are you just taking my word for it? Exactly. Test it yourself. He found the solution for a finite and given solution set. Is it the exact culprit for your latency issues? That would be too general to assume. I am not saying this is a magic bullet solution to all performance problems, but am advocating that people understand what is happening behind the scenes when using cfswitch and to be careful of using it in this type of a case. If someone IS using cfswitch in this mannor, it is undoubtedly causing latency, it is just a matter or whether it is enough to be a problem. I have sincere issues myself putting CF logic into my queries. I let the DB handle this type of logic in the form of stored procedures, which will calculate my execution plan for me in advance. I completely agree when possible, but this issue also affects loops as well, not just query loops.

Delimited list problems - a bug?
Hey all, One of my team members just brought to me something strange that to me seems as if it's a bug. If you use multiple delimiters to create a list, and then use a single delimiter to fashion a sub-list, CF treats the sub-list as two elements. Here is an example: cfset myList = 'element 1||element2||element3' cfoutput Single list using || as delim brbr length = #listLen(myList, '||')# br !--- This will produce 3 as expected --- element1 = #listFirst(myList, '||')# br !--- 'element1' as expected --- element2 = #listGetAt(myList, 2, '||')# br!--- 'element2' as expected --- element3 = #listLast(myList, '||')# br !--- 'element3' as expected --- /cfoutput br br cfset myNewList = 'element 1||element2a|element2b||element3' !--- now add a sub-list using a single pipe char --- Sublist using | as delim in a list using || as delim cfoutput length = #listLen(myNewList, '||')# br !--- returns 4?? --- element1 = #listFirst(myNewList, '||')# br!--- 'element1' as expected --- element2 = #listGetAt(myNewList, 2, '||')# br !--- 'element2a' wth?!? This should return 'element2a|element2b' --- element3 = #listLast(myNewList, '||')# br !--- 'element3' as expected --- /cfoutput If I am explicitly telling CF that the delimiter is two pipes, why would it stop when finding only one? I tried this with other delimiters and found the same behavior. Am I crazy or does this appear to be a bug?

But it is explained this way in the documentation. When you provide a list of delimiters it is not an AND list, it is an OR list. Thanks. I did not even consult the doc's on this, I made the assumption that multiple delimiters were treated in an AND fashion. I guess I now know what they mean by the saying Making assumptions... Thanks for the clarification guys. I can't say that I've ever run into a situation where I needed the OR operation, seems to me the AND operation is more natural.

If you change all your date fields to one of the following it will solve your problem: 1. For example DateElected cfqueryparam cfsqltype=cf_sql_date value=#arguments.DateElected# null=#len(arguments.DateElected)# 2. cfif len(arguments.DateElected)#arguments.DateElected#cfelseNULL/cfif This will cause NULL to be passed to the database if the DateElected variable is an empty string.

RE: Date Problem
Yeah, guess I am gonna have to use the CFIF option. SP's are not allowed on the DB2 server for the city. We are getting our own SQL Server and CF Server soon though, so I get to re-write the app using SP's. As I understand it, using the CFQUERYPARAM tag is on the ColdFusion side and simply creates a prepared statement that is sent to the database and does not involve the use of stored procedures.

Intro to e-commerce transactions
I'm currently working on my first e-commerce solution (don't ask me how that's even possible after this many years as a developer!). Much of the back end work I'm very comfortable with, but I've never worked with online payment processing. Can anyone suggest some resources to the payment portion for this type of solution? I'm aware of the mail-order aspect to processing orders (not billing until the product ships) and have built that functionality into the application. I'm more concerned with the actual communication and authorization of payments. Can anyone suggest a good credit card processing service or give me any advice on this?

String Math Parser
I am currently creating a wiki style parsing engine for the lack of a
better description. To date I have all the HTML elements parsing that I
need, but one of the requirements that I have is to allow the end user
to input variables from our system (kind of a merge field) and allow
them to perform math operations on them. I was hoping that someone
might know of an existing CF math parsing engine / code that I might be
able to get a foothold on how to accomplish this.
Anyone know of an existing open source library?
The current requirement is to allow for basic arithmetic but including
nesting parenthesis for more complex equations. I have some ideas for
the basic math, but when getting into nesting equations is where I get a
little fuzzy.
This is what I am trying to achieve in wiki markup:
[b]Welcome[/b]
[p]
Product Commission is
[math]({product_price}-{product_credits})*{commission_rate}[/math]
[/p]
Using my existing code I can get it to generate the correct [math] like:
(10-500)*.15
I thought of simply tossing an eval() around this, but it seems like a
major hack and does not allow for more complex equations that might come
up later.
Anyone have any ideas?

RE: CF on Apache
Just one little problem. Apache 2.2.4 doesn't have an 'apache.exe' file in it's bin folder. Any ideas? All help is appreciated. When we moved to SVN I set up all our developers with CF7 / Apache 2. I found that if my configuration file had any problems in it that apache would fail to start, which sounds like what you are running into so I would look to the httpd.conf file and ensure that all the settings are set correctly. When I did this the first time, I configured the server with all the settings I needed without the CF settings (using settings copied from httpd.default.conf). Once I had the web server configured I copied in the CF specific settings and tweaked them until I got everything working. The great thing about this setup is that once configured you can simply copy the httpd.conf file to all developers workstations and they immediately work.

RE: Getting changed fields from database using an audit table
Doug, After seeing your intended output the query will need to change a bit, but I think I understand what you are after. Could you do something like this: (beware this SQL psudeo-code it's untested) declare @User_modify table( UserID int, FieldName nvarchar(50), NewValue nvarchar(50) ) declare @col sysname declare colList cursor local fast_forward for select COLUMN_NAME fromINFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'USER_UPDATED' open colList -- loop over the column list @col will hold the current column fetch next from colList into @col while (@@fetch_status = 0) begin -- insert matching records into the temp table insert into @User_Modify(UserId, FieldName, newValue) SELECT userid, @col, cast(@col as sysname) as newValue FROM users where @col cfqueryparam type=cf_sql_date value=#since# fetch next from colList into @col end close colList deallocate colList select * from @user_modify This way you could offload a lot of the processing onto the SQL server. HTH, Rich Kroll -Original Message- From: Doug Bezona [mailto:[EMAIL PROTECTED] Sent: Tuesday, January 09, 2007 1:59 PM To: CF-Talk Subject: RE: Getting changed fields from database using an audit table Thanks Unfortunately, simply having the two tables joined doesn't help. The issue isn't getting the correct data, it's simply that to get the output I need, I have to loop over each column in each record to see which column has been updated in a given time period, and output the info about that column. USERS has a single lastupdated column, just so we know when it was updated. USER_UPDATED has most of the same columns as USERS, but each column just holds a date stamp of the last time the corresponding field was updated in USERS The data looks something like this: USERS: UserIDFirstnameLastname ------ 1 John Doe 2 Jane Smith USER_UPDATE: UserIDFirstnameLastname ---- --- 1 07/08/2005 10/31/2006 2 05/10/20067/15/2006 The output I am looking for is this, given an input date of 01/01/2006: UserID FieldNameValue --- --- --- 1 Lastname Doe 2 Firstname Jane 2 Lastname Smith The code produces the exact output I need, so the basic logic is fine (if not as fast as I need it to be). The queries run in a few milliseconds, so they aren't the bottleneck. It's the looping through each column in each record of the resultset to check the updated date of each field when it's 12000 records x 89 columns that's the bottleneck. ~| Create robust enterprise, web RIAs.

RE: Modifying an existing PDF
Is it possible, using the built in features of CF, to modify and add information on top of an existing pdf file? What do you mean by modify and add information? Are you referring to filling in PDF Forms? Adding additional pages to the end of an existing page? Modifying existing text inside an existing PDF? The reason I ask is that I've done some work in this area. We had a requirement to populate pre-existing PDF's with dynamic data, and a later requirement to dynamically add additional pages to the end of these pre-configured PDF documents and insert user defined text. The solution I found (which can be tricky depending on your java knowledge) was to use the iText Java library. An older version of iText ships with CF and is what powers CFDocument from what I understand. Using the iText library you can get to virtually every part of a PDF, but some are a lot harder to manipulate than others. The link to the home of iText is http://www.lowagie.com/iText/ Depending what you are trying to do I might be able to provide some code samples of how to manipulate PDFs within CF.

RE: CF and OOP - Controller
Firstly, I applaud your work in attempting to truly understand how OO works and how to apply it to CF. I just wanted to chime in and give you a few things to think about when you are trying to understand / build an MVC app. I looked at the problem of building an MVC application and looked to Mach-ii, MG, and Fusebox as possible options. When I attempted to build my own MVC architecture one of the hurdles that I encountered was how the controller knew what it was supposed to do. I knew that it was to act as the 'traffic cop', but was really confused as to how IT knew what was currently happening. In my research I dug through the code of every MVC framework that I could find. The one thing that I saw repeated for all web based MVC patterns was that the framework acted as the controller. When you look at the existing OO frameworks, many of them use an XML config file to help 'wire' everything together and use an 'event' driven methodology to define when things happen. You define your model and tell the controller how each event affects the model and which views are used for display. The framework manages transforming all url and form variables into its internally used object (in Mach-ii this is the event object) to ensure your model / view do not need to know anything about scopes. In your original example of a user logging in, your userObject would be the model and accept arguments of username / password. Your view would have a form element that had inputs for both the username and password and when submitted would cause the controller to be invoked (usually event driven, eg. index.cfm?event=loginUser). This is where XML config files usually come in. Generally, you need to map an action to model components as well as what views to generate once the operation is complete. This all becomes significantly more complex when you begin to think about different logic paths that might need to be followed depending on the current request. For example in your scenario, what happens when the user login fails? What about if it succeeds? What if you want to add logging into the process? You could have the model generate new 'events' or have your components simply return success / failure response which your controller could then consume and dispatch other events. When I began looking at the previously mentioned frameworks as a controller to my application, I began to look more closely at the model portion of application. I highly suggest looking at the problem in slices when trying to 'get' OO. Once I focused my attention on modeling real world things in my application and focused less on the 'traffic cop' it made it much easier for me to see how each object should be constructed as well as relate to other objects in the system. This perceptual shift was a kind of spring board to me truly getting OO. Once I began designing components like this, I began to *see* the benefits of architectural patterns like DAO, Factory, etc. Once I saw the benefits of these patterns, I looked back at the frameworks and examined the controller layer and saw them applied there as well. That was when I could actually see *why* they had used them and what problems they solved. Good luck and I hope you enjoy the journey! HTH Rich Kroll ~| Create robust enterprise, web RIAs.

RE: Simple source control
Claude, I recently went through exactly what you are dealing with now. Our development environment began with all developers working against the exact same code base, where developers would overwrite each others changes as well as break code during the development process that would affect other people. Don't even get me started on the problems we ran into when deploying to production servers. Our first step into source control was to use Microsoft VSS which used the lock model. This worked ok for a short time but once our development team grew, having people constantly forced to wait for files to be unlocked became unbearable and began to kill our productivity. We recently (about 8 months ago) converted to SVN where each developer has a local copy of the code, makes their changes and then commits those changes to the main code. With a team of 20 developers constantly working with the same files, conflicts happen VERY rarely, and when they do it is 99% of the time a miscommunication as to what should be changed in that part of the code. Most of the time when code is committed, SVN merges in changes from other developers transparently. This idea at first sounds scary, but in practice it has been a TREMENDOUS advantage in terms of productivity, communication, and stability of our code. The ability to look back in time at our code has been invaluable in countless ways. If a bug was introduced, we can simply merge that change out of the code while we fix it. It truly is an unbelievable tool. The only downside that we've experienced is that the computers we use to work on have to be a little more beefy to be able to run local copies of our applications (CF, SQL, TSVN, Eclipse, etc.). IMO the merging solution implies more overhead and clumsiness than no solution at all. Hopefully I have communicated how this is truly not the case in a real world scenario (or at least in ours). If you have the chance, save yourself the growing pains of moving to a lock model, then outgrowing it and moving to SVN. If you are going to have your development team learn a new methodology for how they deal with source, have them learn how to effectively use SVN. In the end, we went from a development team of 5 using no source control to MS VSS, to over 20 developers using SVN. I can attest to the struggles of converting to source control, as well as not moving to SVN first. I hope that my experiences will help you in your efforts.

RE: Simple source control
Yes. But why would would you want to automatically download code from there? To make sure that a programmer will get the last version before he starts working on a file. At least, this should be checked by the system when a user request a lock on a file. Making sure that you are working on the latest version of a file is not automatic, but does not hurt anything if it is not the latest either. When the developer attempts to commit their changes, SVN will simply notify them that their code is out of date and force them to update their local copy prior to committing. When they update, any conflicts will be caught, merged / fixed, and they are then free to commit the changes. I think this is beginning to become a relentless circle of you challenging source control systems and people that use them offering up solutions to the challenges you propose. In any event, you have heard from every response that a SCM tool will solve the problems you are facing as well as many problems you have YET to face. Each SCM tool that has been proposed (CVS, SVN, VSS), now it is just a matter of deciding which will best suit your needs. I've personally given you advice based on experience walking the road that you seem to be currently on. You can take it or discard it, but the answers from this list are going to stay the same: You need a source control tool. And the 3 that are most widely used are: SVN - Based on CVS and addresses some of its shortcomings CVS - Tried and true with some small limitations. VSS - M$'s SCM and IMO a pain to work with.

RE: cffunction with a loop inside - need some advice
I was not sure if you needed to invoke this as a web service or simply

database, I would refactor this to take an array of structures of
'classes' as an argument and then loop over the array and do the inserts
from that.

Subject: cffunction with a loop inside - need some advice
OK - before I tried turning this particular problem into a service, I
had a simple query like this, which works (examples simplified for
clarity, whatever that is!):
cfloop from=1 to=#form.totalPERSONS# index=idx
cfquery name=WRITE_ENROLL
INSERT INTO participants (
enrID,
part_class )
VALUES (
#evaluate(form.enrID#idx#)#,
'#evaluate(form.part_class#idx#)#' )
/cfquery
/cfloop
The function to handle this once converted is failing with 'Can't
generate stubblan, blah so I've got a syntax problem or just
simply don't know what I'm doing trying to translate the above.
Here's what I've got:
To invoke the beast:
cfinvoke webservice=myWEBSERVICE
method=ENROLLMENTS
WStotalPERSONS=#form.totalPERSONS#
cfloop from=1 to=#form.totalPERSONS# index=idx
WSenrID#idx#=#evaluate(form.enrID#idx#)#
WSpart_class#idx#=#evaluate(form.part_class#idx#)#
/cfloop
And here's the function:
cffunction name=ENROLLMENT_TWO
access=remote
returntype=query
cfargument name=WStotalPERSONS type=numeric /
cfloop from=1 to=#arguments.WStotalPERSONS# index=idx
cfargument name=WSenrID#idx# type=string /
cfargument name=WSpart_class#idx# type=string /

cfquery name=WRITE_ENROLL
INSERT INTO participants (
enrID,
part_class )

WSenrID#idx#,
'WSpart_class#idx#)#' )
/cfquery

I probably need to rethink the way this particular function has to
work,
but I desperately need some pointers please!

RE: Determine database field type
The first step would be to find out what type of field I am working with. I am don't know how to do that. You can use the information_schema if you are using MSSQL to determine the data type of the column. Then I'll have to figure out how to make it a date field for excel. You can create a new spreadsheet and format each column with a different data type, then save as HTML. Once you do this you will have the CSS markup and can make your own custom classes. Then when you export to excel, simply assign those classes in your generated HTML. HTH Rich Kroll ~| Create robust enterprise, web RIAs.

RE: cfinput validate=SubmitOnce
One way this can be solved is use a synchronized token to manage the submittal (Synchronizer Token, Core J2EE Patterns). The way this works is you create a unique token, for example a UUID and store this in the user's session. When the user reaches your form you store the token in a hidden input field. On the processing page you check if the tokens match and if so begin validating the data. If any data validation fails return them to the form to correct the problem. If the data validation passes, create a new token for the user and overwrite the one in the session. If the user presses the back button and resubmits, the tokens do not match and you can alert the users of the problem.

RE: Framework choices
I was specifically wondering if ANY of the frameworks support code re-use in the form that I mentioned in the orginal post. i.e. can I write the model and views for one system and keep them in one location accessile to several applications that mayuse parts or all of it's functionality. IMO it's always a good idea to keep your model separated from the framework you choose to use. I use Mach-II for most of my development (so I am a bit biased). When designing an application, I create my model completely detached from the framework. Once the model is built I then create the event listeners that draw upon my model. This allows me to use the model in different applications if necessary, as well as it keeps my model framework agnostic. In mach-ii you can create layered views, which will allow you to create component-like views. This allows me to reuse certain view portions around the application. This depends heavily on how you design your views. Also not mentioned in my original post but occurring to me here is that the site is largely dynamic in that the same code needs to serve different content for different sites that use the same backend. All the dynamic information for the content are retreived from a database through stored procedures. So these procedures would need to be executed on all pages with dirreent arguments. Is each 'site' all part of one application? It seems as though you could have the listener determine which arguments to pass to your stored procedure depending on parameters passed in an event object. All the points mentioned above seem impossible to implement in Model-Glue (without destroying the performance of the site). IF this is not the case can someone set me straight? Otherwise could someone recommend another framework. Or better yet give me the difinitive that I need to be rolling my own. I've only worked with MG to a small degree, but from my experiments many of the core concepts are the same between MG and MII so most (if not all) of what you are attempting should be possible.

JVM Server Memory
Hello all, I remember a post not too long ago talking about the JVM and it's max size on a windows 32bit server having a celing of 1.3gb. We've got a server that has 3gb of ram, and about 1.8gb of that is going unused even under peak load. One of my colleagues decided to up the -XmxNx value of the JVM to 2gb to attempt to allocate more memory and increase performance. This caused CF to fail on startup, and once the setting was lowered, CF started fine again. As is understand it there are three major settings to tweak in the JVM (where N is the memory size) and please forgive me as I'm new to JVM configuration: -XmsNm - minimum GC size -XmxNm - maximum GC size -XX:MaxPermSize=Nm - the maximum permanent size For our application we have quite a large number of objects stored in the application scope and would like to increase the amount of ram allocated to jrun / JVM. Am I correct in that increasing the MaxPermSize from its default of 128m to a larger amount (say 512m) will increase the available memory of the JVM for objects being stored for a much longer period of time (like those in application scope)? Our current settings for our JVM are: -Xms512m -Xmx1024m -XX:MaxPermSize=128m We are not getting a ton of GC that is degrading performance, but we seem to be having the system slow down dramatically when JRun / JVM hits the 1gb mark. So our thought was to raise the amount of memory in the JVM available to JRun. Am I right in my understanding of the differences in the settings?

I18N and money
We have just picked up our first international clients and are beginning down the road of I18N. Initially we were planning to just support locale specific dates and money, which we would store in US dollars and in a US date format within our database. We offer a software solution that is a sales management tool, so we have inventory, deposits, etc. I just got a request to look into how the following scenario would work: Client's locale is say en_GB (UK), but they have remote sales people in say Germany. When the remote sales staff use the system, it displays everything in pounds as their project is configured to use en_GB. 1. Would the salesperson be forced to input the customers order in pounds even know the local currency for that region is euro's? 2. Should we build in a currency converter to the application? 3. Instead of just lsnumberformat() and lseurocurrencyformat(), should we be converting the amounts to local currency prior to display, and back again when we need to get user input? I have a feeling this is something that a lot of people have tackled before and any pointers in the right direction would be extremely helpful.

I've got a resourceBundle CFC set up that uses the Java ICU4J library to manage my RBs. My problem comes up when I'm using getLocale() to return the current locale. The CF docs state The current locale value, as an English string. If a locale has a Java name and a name that ColdFusion MX used prior to the ColdFusion MX 7 release (for example, en_US and English (US)), ColdFusion MX returns the ColdFusion name (for example, English (US)). The ICU4J library expects java locales, and when CF returns a string instead of the java locale, my app defaults back to English as it does not know how to parse the string equivalent. Is there a way to force CF7 to return the java locale, or perhaps another way to deal with this problem?

RE: Locale problems
why use icu4j for this? especially if you're *just* using core java locales rather than ULocale? if you want *all* the CLDR locales you need to use icu4j's ULocale. I was going to use the ICU4J libraries as they included extra features for calendars, etc. which I thought could come in handy down the road. In my CFC I was actually using com.ibm.icu.util.ULocale. well for one thing, getLocale() returns the *server* locale as a cf locale, i imagine you'd want the user's locale? how are you determining or handling the user locale? I was under the impression that getLocale() and setLocale() worked on the current request. I was using setLocale(myQuery.userLocale) to set the current request to the users locale and then within my CFC manage working with that locale to get the correct RB file. When working with what I have set up now, I have a few lines in my application.cfc that uses setLocale(userLocale) to set their requests to the correct locale. But in certain cases where I've got say us_GB stored for the user, CF will return English(UK) which forces my CFC to fail to render things correctly. Is there another way I should handle this?

RE: Database design question
The one table design that Michael is describing will hold all your categories and sub-categories, as well as any further nesting that you might need. For example: Cat_id, category_name, parent_id 1, category 1, NULL 2, category 2, NULL 25, sub-category 1, 1 26, sub-category 2, 1 49, sub-category 49,2 200,sub-sub category 1, 2 Etc. This single table design lets you nest sub-categories as deep as you need to go. As someone previously stated, the major drawback to this design is that you can only have one parent for each item. If you need an item to have more than one parent, you would have to develop a two table design. Hope that clears things up a bit.

RE: Global vars in CFC's :-)
I am a big proponent of method A. My reasoning is that it cleanly separates instance data from other data in the object. I create a debug() method in all my objects that return the instance struct, which gives a very clean way to see what data is within an object. Additionally you can use the instance data to implement the memento design pattern. This pattern allows you to easily store the state of an object and return to an earlier state with a method like MyObject.setMemento(instance) to populate the object with a stored state. Even if this functionality is not something I use all the time, I like the flexibility it offers if the need ever arises. My 2 cents. My 2 cents.

The problem you are seeing is that when you are comparing orderdate = now() that it's including minutes and seconds, which will not equal your record.

RE: Development Environment Setup
I feel your pain and have recently worked through many of the problems that you are currently struggling with. This is the solution that we found works for us and is in no way best practice or the right way, but hey, it works for us with 20 developers all working on the same set of code! We decided to have each developer run a local copy of CF under apache as well as installing TortoiseSVN to interact with SVN (Subversion). Our IT guys helped me put together an installer package that had the apache conf files as well as all the necessary installers. We wrote a few CF files that used the admin API to create all the necessary datasources etc. This enables us to bring a computer from start to configured in about an hour. We have two environments, QA and production that we deploy to. When we are ready to QA a release, we create a branch from the trunk and have our QA server switch to that branch for testing. If there are any problems, we update the trunk and merge those changes into the release branch. Once this branch is ready for deployment onto our live servers we simply have the live servers switch to the new release branch. Currently we are not using many automated processes to accomplish this (outside of SVN) but I'm looking into ANT and CruiseControl as I've heard really great things about both for automated deployments. In regards to your question about the logistical nightmare of keeping all developers in sync...well SVN handles all of it from a code perspective. When a developer attempts to commit changes to the repository, they are notified that their local copy is out of date and they must sync with the server prior to any commits. On the data side, we have data environments (development, qa, live) and all developers have their CF datasources pointed to our dev DB server.

I know it's been asked before, I would like your ideas on our specific setup: Currently we maintain several applications under many websites, on a single development server (CFMX7 and SQL2000). Developers work direct on the shared development server via VSS (do some work, save it, check it in to see if it works...very time consuming). Releases are then done by the tech support guys, who get sent a list of things to push to test (which is currently a manual task). Developers have no access to SQL Admin or CF Admin. As you can guess, this isn't the best, and I personally would like to see us using a better source control system (Subversion?). I would also the like the source control and release process to be a lot more transparent in the overall process. I have seen mentions of people having devs running their own instances of CF/SQL, but how the hell do you keep these up to date without creating a logistical nightmare (i.e making sure every developer is in sync with both code and external requirements such as IIS setup?)

Here is my post-commit script, though I don't think the problem is here as most of the time it's working fine...it only chokes if one of the directories has been moved / deleted in the underlying file structure: @echo Processing Cleanup C:\progra~1\subversion\bin\svn.exe cleanup c:\webserver\site C:\progra~1\subversion\bin\svn.exe cleanup c:\webserver\admin @echo Starting Dev Deployment C:\progra~1\subversion\bin\svn.exe update C:\webserver\site C:\progra~1\subversion\bin\svn.exe update C:\webserver\admin @echo Deployment complete -Original Message- From: Jochem van Dieten [mailto:[EMAIL PROTECTED] Sent: Thursday, July 13, 2006 2:41 AM To: CF-Talk Subject: Re: OT: SVN Error Can you show us the script?

RE: FAQ?
I know I'd sign up for notification for when new tips are added. I know I don't check back that often, only when a need arises and I'm looking for a solution.

I've considered a Subscribe mode for people who want to get informed on each entry. Since the site has an RSS feed I figured it wasn't quite as critical. But it would be nice to add email notification.

Why not set up a Tip of the Day (or Tip of the Week) and deliver it to subscriber's inboxes, where they can then save the tips to archives...searchable on their own systems. Also, when new tips are added, automatic email notice goes out to all subscribers with information about the tip. Why wait for them to go to the site? Take the material to them...you're traffic will pick up a lot, I'll wager, too...
