Instantiating CFCS as application variable

• Loading Application Variable from a database

  I read upward on the use of XML and INI files to do this, but I really want to do with my database.
  
  I want to create a table in my database (MySQL) may be called settings_application, and it contains 3 columns (id, key, value).
  
  Example of a table
  
  settings_application
  
  ID | Key | Value
  ------------------------------------------------------------------------
  1. DSN | myDatabase
  2. pageHits | 38272
  3. encryptionKey | asdkjfadfw3r23e2
  
  So, I want to create a CFC that somehow will read all variables in the table and start to loop through them and turn them into application variables (in the scope).
  
  For example Application.dsn, Application.pageHits, Application.encryptionKey. I did it with the help of a cfloop and large cfif condition.
  
  The problem in this process is that I don't want to change the CFC code is I add a new parameter.
  
  If I added the following to the database...
  
  ID | Key | Value
  ------------------------------------------------------------------------
  4. author | Josh
  5. E-mail | [email protected]
  
  I don't want to go then edit the cfif tags adding:
  < cfelseif settings.key EQ 'author' > < cfset Application.author = settings.value >
  < cfelseif settings.key EQ 'email' > < cfset Application.email = settings.value >
  
  I hope I can do this. Please help sort you can. Thank you!

• Wide application variable

  What is the best way to implement a broad Application Variable.
  Here's what I want to accomplish. We have several users to get different data into the database. I want to filter the data, users see based on a column he'll call group appearing in each table.
  My thought was to put a drop-down list on the page of connection or of a page and that they would choose the data of the group to which they want to see.
  Then on each page queries for this page would have a where clause clause that would say where Group =: MY__APP_Variable.
  
  I don't know if it is the best way to achieve this.
  and if it's the best way that I am not sure how fully implent the application setting.
  I think I would create some type of variable under shared components
  then when they select the value in the drop-down on the connection I would equal to that variable.
  
  I don't know exactly how to proceed.
  Thoughts?
  Thank you

  qtjr, I asked you about the number of reports, so that if you have less number of reports, then you can have the option to change the Group on the screen instead of going to the first page to change the report. You have reports of 50 people or more, so is probably not a good option. Allow the user to select a group after their connection and set the value to a level application element.

  You can use a page level item, but I think a part of application-level will be a better option.

  Thank you

• Assign the value to the Application Variable via javascript

  Hello
  
  How can I assign value to an element of the application (not the page element) through javascript.
  
  I tried to assign the value as follows:
  
  $s ('F150_REGION_TEMP', region);
  
  where F150_REGION_TEMP is the application variable and 'region' is populated value in javascript.

• Inaccessible application variables of pages...

  Hello
  
  I'm trying to use variables to application of a CFC but CF tells me that they are not defined.
  
  Here is the code example:

  Although you can use cflock when you call SystemFramework manually. If I remember correctly, CF only lock the application scope when it calls SystemFramework automatically starts the application. It does not block when you call this function manually.

• Write real Labview 8.2 Twincat embeded application variables

  Hello

  I am currently using Labview to write and read variables defined by an embedded application of Twincat.

  I set the following variables in Twincat:

  Lab_lecture_real % MW100: REAL;
  Lab_ecriture_real to % MW102: REAL;

  Mo1% Lab_lecture_bool: BOOL;
  Lab_ecriture_bool % MB2: BOOL;

  Based on the VI given by Beckhoff to Twincat ADS/OCX (http://infosys.beckhoff.com/english.php?content=../content/1033/tcsample_labview/html/tcsample_labvi... =), I managed to read the variables 'Lab_ecriture_real' and 'Lab_ecriture_bool' and write through 'Lab_lecture_bool '.

  However, I forgot to write in "Lab_lecture_real", which is a real.

  I enclose my VI, everything seems to be connected correctly. However, I do not understand why it works for a Boolean variable, rather than a true. The method used for writing a real is perhaps different from Boolean.

  Can you stress me about this, please?

  Kind regards

  Stéphane

  Why you set the length for the REAL number 8 in VI?

  It is in the documentation of the OCX elsewhere?

• How to save the settings of the application (variables)?

• CFC's global variables

  I'm looking for that certain variables in a cfc available in all the functions of this cfc. I used to do that with properties, but just discovered a problem with this approach. Now I'm trying to normal variables, but I find that not all keep them their value. The model seems to be, if the variable has been set to a point it loses its value, otherwise it keeps things.
  
  For example
  Model call:
  args = structNew();
  args. StartDate = "2006-09-01;
  args. EndDate = "2006-09-01;
  
  ABC = CreateObject ("component", "BlocksAndClosures");
  x = abc.init (argumentcollection = args);
  z = abc.blocks ();
  
  -------------------------------
  Beginning of cfc
  < cfscript >
  WhatToUse = "undefined";
  StartDate = '1990-01-01 ";
  EndDate = "1993-01-01";
  x = true;
  < / cfscript >
  
  ----------------
  the init function code
  StartDate = CreateOdbcDate (argument. StartDate);
  EndDate = CreateOdbcDate (argument. EndDate);
  WhatToUse = "something";
  
  < cfdump var = "#variables #" >
  -----------------------
  blocks function code
  < cfdump var = "#variables #" >
  
  ------------------------------------
  When I emptied the variables at the end of the init function, all variables have the new values. It is to be expected. When I dump them in function blocks, WhatToUse is now equal to "something else" which comes from the init function. However, the date two variables have values of 1900 and 1993 which seem to mean they have been reset.
  
  I can work around this problem, but no one knows why not all variables of EFA behaved the same when the block function was called?

  Could get you a collision of scope with the variables of your global variables and arguments? What happens if you rename the arguments or the global vars? I got the thing in global variables in CFCS to work before, but I usually make sure that the name of global variables is different from my local variables or entry.

• assign value to select the application variable

  Hi, is it possible to do something like:
  
  SET the VARIABLE rq_var = (select 'table - param'.param_value from test_obiee where 'table - param'.param_value = ' @{ps_var} "");
  
  or
  
  @{ps_var2} = (select 'table - param'.param_value from test_obiee where 'table - param'.param_value = ' @{ps_var} "");
  
  If so, this action is possible before loading data from db (type something under "Prefix" under "Advance of Clauses SQL" in the title of the page in the tab 'Advanced' in the 'Answers')
  
  Thank you!!

  I hear you, response, which was the thread I would have done you.

  Ok then. Create static variables repository called HUNDREDS and MILLIONS of worth 100 and 1000000. Then you actually use the quick captured values to switch between variable names instead of changing the content of a variable.

  You have to build the formula by concatenation, so that he could read something like this then:

  Fact. "" My way "/" VALUEOF ("' | ')" @{vPromptedDivisor} {HUNDRED} | '")'

  See you soon,.

• Application.cfm to Application.cfc: UNDEFINED Variables?

  I have an application that has been created in CF8... the previous programmer used Application.cfm. I prefer to use Application.cfc... so, I migrated the code to a .cfc... However, none of the variables seem to be defined. I placed the SystemFramework of onSessionStart, onRequestStart, rename the application whenever I change... I am constantly is UNDEFINED for my variables.

  Can someone tell me why this is?

  Second, for global variables such as serverRoot, secureServer, insecureServer, I guess that is the best place for these VARS SystemFramework... but for application objects, status, etc., it would be preferable to have these elsewhere? What is the harm in having all my variables global application within the SystemFramework?... .assuming they never defined. :/

  You are out of the method before anything can run. Remove the cfreturn or move it to the end of the function. Other than the lack of a few citations (maybe a problem of forum), it works fine.

  
           
  This will allow us to call any function object without instantiating
  APPLICATION.user = createObject ("component", "apps.com.User");

  These application variables must be declared in SystemFramework too. Otherwise, you re-create the shared components whenever a new user session starts.

• Scope of variables: Application.cfm vs Application.cfc - very confusing

  Hi all
  
  ColdFusion newbie here, please bear with me :)
  
  I am currently responsible for the upgrade of a huge project of ColdFusion 5 (more than 1,000 pages of CF) for ColdFusion 8, I tried to refactor old code in CFCS, but ran into a problem with the scope of variables, or lack thereof.
  
  In the old application, there is a single Application.cfm in which a bunch of global variables are defined, without scope, as:
  < CFSCRIPT >
  ...
  PrimaryDataSource = 'TestDB '.
  ...
  < / CFSCRIPT >
  
  It seems that variables defined as this can be viewed very well in all CFM pages using #PrimaryDataSource #, but not in one of my new pages of CFCS.
  
  What should I do for that these variables global scopeless available for CFCS? Also, what actually means if global variables are defined without any scope?
  
  I'm really new to ColdFusion, so I would be very grateful if someone could throw a light here!
  Thanks in advance.

  They are not global variables. Local variables in the variables
  scope. On one of your current pages, PrimaryDataSource would be the same
  as variables. PrimaryDataSource.

  How it works currently, is that Application.cfm is an automatic
  included file. That is, for every single request, this file is
  automatically included at the beginning of the request and all these
  local variables are defined and exist only for the duration of this request.

  When you start to refactor the code in the CFC, you'll have to
  get a better handle on how to deal with these types of broad application
  variables. There are a few choices.

  One, you can create them as truly global variables is in the
  application or session brought rather than local and temporary variables
  scope. You use depends on whether the value of a variable is the
  even for all users [app] or may be unique to each user [session].

  Second, you can set these variables within CFC itself as one
  variable local "variables" scope inside the CFC. These variables will be
  live as long as an instance of the CFC lives. So if the CFC
  has persisted in session or application scope, then the data of "variables".
  inside she will persist.

  It is a great subject and a response email will not cover
  all the ins and outs of it. You are looking at a huge task and will want to
  to do a lot of reading. I suggest starting with the ColdFusion
  documentation. It has good chapters that cover all these details
  about the various scopes of variables and other chapters which cover
  Components. After ColdFusion documentation, there are now three
  volume "ColdFusion Web Application Construction Kit" by Ben Forta et al.
  Finally, there is a vast internet blogs, discussion lists and
  Tutorials that cover all these topics in lower and more details.

• Strange problem of Application.cfc included

  It's hard to explain, so I hope this has meaning. Here goes...

  I have an Application.cfc in the root of my site that defines some variables.  I then an Application.cfc in each subdirectory (call each of these subdirectories a site) that includes the root Applicaiton.cfc.  I have also one includes the folder located in the root directory that I use in each site for pages that I shoot using the tag cfinclude referring to variables defined in the root Application.cfc and Application.cfc site.  For some reason if I touched the page in includes it the directory directly everything seems to work very well.  I can then shuts down for the pages of different site that use cfinclude to pull in files in the directory, and that works very well also.  However, if back us the next day and do not go directly to the page in the directory first and just go to one of the pages that pulls in the include files, we get an error saying that the variables in the root Application.cfc was not found.  I don't know where to start trying to debug this?

  This is all the code of the root Application.cfc less other variables:

  < cfproperty output = "false" >
  
  <!-name of the application, must be unique-->
  < cfset myIdName = "openenrollment" >
  
  <!--> run before the request is processed
  < cffunction name = "onRequestStart" returnType = exit "boolean" = "false" >
  < cfargument = 'page' type name = "string" required = "true" >
  < cfset APPLICATION.memberDisease = True >
  < cfreturn true >
  < / cffunction >

  < / cfproperty >

  This is all the code of one of the files of the site Application.cfc less other variables:

  < cfproperty output = "false" extends = "oe. Application">
  
  <!--> run before the request is processed
  < cffunction name = "onRequestStart" returnType = exit "boolean" = "false" >
  < cfargument = 'page' type name = "string" required = "true" >
  < cfset APPLICATION.group = "demo" >
  < cfreturn true >
  < / cffunction >

  < / cfproperty >

  The root of this site is in fact a subdirectory named oe that is located in the root of the large site, so the root Application.cfc file lives in the /oe directory.  Understand that are in the/oe/includes directory and in the example above the file Application.cfc is in the directory/demo/oe /.

  I'm new to this kind of things of cfc, so any help is GREATLY appreciated.

  Thank you!

  You're right, it's complicated.

  With a single pass through your explanation, my first theory is that the in the root of your Application.cfc OnRequestStart does not work.

  Since you have an OnRequestStart function in the Sub Application.cfc file, it replaces the OnRequestStart in the base file.  Both do not work.

  But when you run a file directly in the directory includes, this file does not use a sub Application.cfc file so it does work the Basic Application.cfc file and so this function OnRequestStart() is used.

  IF this theory is true, the solution would be to call the OnRequestStart() function parent, starting with the child OnRequestStart function.

  That would probably look like this.

• How you include the doctype in Application.cfc?

  I am trying to convert an Application.cfm-Application.cfc file and in the cfm file, I got the following:

  <! - set the content type to ISO-8859-1, otherwise the default is UTF - 8->
  < cfcontent type = text/html"; charset = ISO-8859-1 ">"

  <! - set the doctype for all documents - >
  < ! DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict / / IN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd" > ""
  " < html xmlns =" http://www.w3.org/1999/xhtml ">

  I think I put the cfcontent in the SystemFramework function as well as other application variables.  No matter what I do, nothing happens the doctype to appear on the pages. Where do you put that in the SWC file?

  Thank you!

  Holli

  If you want the OUTPUT of the OnRequestStart function, you must use OnRequest() and include the generated output.

  Really, which means you could probably do all what you want just in the OnRequest method, but which belongs to you.

  It is not that OnRequest() breaks webservices, ajax called ect.  OnRequest runs for ALL applications before the Web service request, ajax calls ect.

  Then, if anything method OnRequest adds content, such as the content of your topic, all applications, including Web services and ajax calls.  99.9% of the time, which added content will break the format and avoid thus the functionality of these web service and ajax requests.

  It is not hard to get around.

  (1) have a smarter onRequest method which includes when he meets the demands of ajax or Web service and not to provide content that will break.

  (2) make your resource webservice and ajax inside a different directory with another Application.cfc file with a different (or no) onRequest method.

  (3) as Adam said, don't put content in your Application.cfc but use any number of other methods to apply this type of standard output to all views.

• definition of variables in a CFC

  Is it possible to put the application or session from a CFC variables. I know this isn't the typical programming, but I have a situation where I would have a CFC function to set a session or application variable to use in the rest of the application. Is this possible? I ask because I can't make it work.

  > You are right, your proof of concept works. The problem is that

  How these "pages" are accessible since with FCKEditor? They are
  wanted, included, referred to as an instance of the CFC? I suspect traveled, as
  others would not cause the problem.

  > That was always the problem

  Right. If your first message and all subsequent discussions about this
  have something to do with the CFC was actually... Well well... ballocks.

  [crisscrossed front]

  If, as I suspect, you separate requests by the way by directly to
  files in the FCKEditor directory, as opposed to everything being introduced to
  your site dir, then the treatment is different, but simple.

  Back to my previous example file structure:

  Webroot /.
  -site1 /.
  -Application.cfm
  -caller.cfm
  -app.
  -c.cfc
  = Application.cfm
  = someOtherFile.cfm

  (note that two other files that I added)

  Start by creating a virtual directory of the web server that corresponds

  / site/app to the dir/App

  (NB: the value of your FCKConfig.BasePath to point to this virtual directory, in your)
  case)

  Then to have this kind of thing in the new Application.cfm:

  
  - 2, "/")>
  
  

  
  
  

  someOtherFile.cfm
  (stick any old crap in it; it's just something to get to)

  Navigate to /site/app/someOtherFile.cfm and the Application.cfm for the site
  must be executed.

  Find any Application.cfm file in the app and make similar
  adjustments if necessary.
