• 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!

• 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.

• 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)?

• Wide application menu

  Hi all
  
  Maybe a stupid question, but I'm going to really find the right materials on good ol Designer.
  
  I have created a small application and cannot understand how/where I can create application-wide menu bar? In forms, I know where to set it, but how do the best in Designer? I am, of course, all forms to automatically get the same Menu!
  
  Concerning
  Rookie

  You can create a menu in the form designer with the standard options that you want in all its forms (file and editing options, some of your standard functions, etc..). Attach it to all generated menus via préférence generator "the name of the menu template (STMMMB).

  For example if you have a menulearn called designer's HAND, you attach this menu to your form through preference "menu module name otherwise generation implicit menu (FMNDMA). The form then contains the options of standard menu from the menu template, and options (such as calls to other forms) that you have added to the designer to the MAIN menu.

  More info about these preferences in the online help.

• 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.

• Instantiating CFCS as application variable

  I have a CFC (obviously) which works fine if I instantiate in onRequest. But since everyone uses it a lot, I thought it would be better that it is in the form of APPLICATION. CFCS instead.
  
  But now, I get the error
  USER element is not defined in an object of type Java class [Ljava.lang.String; referenced as]
  
  This happens with this code:
  

  If you have added the instantiation of the object at OnApplicationStart() to an application that is already running then there is not in the scope until the application is restarted. You can call OnApplicationStart() programmatically in your Application.cfc or you can just restart coldfusion.

• 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.

• Is it possible to amend an application within the onSessionEnd function variable?

  within the onSessionEnd only service a copy of the Application scope exists, so I'm not sure rellay so you can change a variable indoor onSessionEnd Application

  Read the docs:
  http://www.Adobe.com/LiveDocs/ColdFusion/7/htmldocs/wwhelp/wwhimpl/common/html/wwhelp.htm? Context = ColdFusion_Documentation & file = part_cfm.htm
  In the tag for the attribute "name":
  «For the Application and Session variables: required.»

  In addition, you must create all application variables in SystemFramework and create all session variables in onSessionStart. The first documentation I showed also said to use a name of the lock to access the Application variables, which you don't. Adding statements will help you track if your application calls these methods, even. And there is no way for onSessionEnd to output anything whatsoever, so coming out.

• 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.

• [FAD] A few questions on the article of Timo "JDev: always test your application with the ApplicationModule Pooling disabled.

  Hallo Timo,

  I read your article JDev: always Test Your App with the regrouping of ApplicationModule turns off | JDev & amp; amp; ADF Goodies and I have some doubts.

  • I understand that you have disabled to AM pooling only to show the problem and the applications in production should always work with 'M bundling active. Right?
  • The substitution of activateState and passivateState functions must be performed when the AM is used to store data that is specific to the user. Right?
  • To store the data of the user in the AM, it is necessary to use the mechanisms of session? Or I might just add to the private variables AM (username, name, departmentName,...) to store the information of the user?
  • I see you used the Session instead of HTTPSession class to manage the session. What are the differences between these classes? Session the recommended class to use is?
  • Where can I find which are the main stages of the life of the session and functions to manipulate? 1-2 examples of creation, destruction, making the session which expires after e.g. 10 minutes of user'sinactivity... would be happy if possible.

  Thanks a lot a lot.

  • I understand that you have disabled to AM pooling only to show the problem and the applications in production should always work with 'M bundling active. Right?

  Yes

  • The substitution of activateState and passivateState functions must be performed when the AM is used to store data that is specific to the user. Right?

  Given no, everything must be save in the activation/passivation. If you store something for use wide application and don't save during passivation, he went by activating the module application ID again.

  • To store the data of the user in the AM, it is necessary to use the mechanisms of session? Or I might just add to the private variables AM (username, name, departmentName,...) to store the information of the user?

  I like to keep the info in the plan to use session.

  • I see you used the Session instead of HTTPSession class to manage the session. What are the differences between these classes? Session the recommended class to use is?

  The session that you get from the module of the application is not a http session it's a server session. You cannot use any other class.

  • Where can I find which are the main stages of the life of the session and functions to manipulate? 1-2 examples of creation, destruction, making the session which expires after e.g. 10 minutes of user'sinactivity... would be happy if possible.

  The documentation is always a good starting point. The best description I know is from the book "Guide Oracle ADF developer real world ' by Jobinesh Purushothaman. If you google a bit you will find another description too. Don't know what you want to know about the creation and destruction of the sessions that you do yourself. To set the time-out setting for the http session, you can change the value of "session timeout" in the web xml file.

• On TV 40L7335D can't connect on WiDi

  I have the Toshiba tv that comes with Intel Widi 40L7335D. I tried to connect my laptop Toshiba A660 satellite-190.

  I got to the point where the TV is trying to get the IP and... That's all knowledge I get the message on the TV screen: 'Connected to Intel WiDi application' and then «I can't get the address network...» "In the meanwhile the Intel WiFi software tool I see that the TV has an IP address assigned, however, the process seems to be interrupted.

  I tried to restart the laptop, restart the TV, disabled the firewall, the TV firmware upgrade (version: 7.1.90.34.01.1) and it did not help.

  The version of the application on the laptop Intel Wireless Display: 1.2.20.00. Pretty old, but Toshiba is suply a newer.

  I'm sure that card WiDi of this laptop works fine, because I can use it on the Netgear WiDi adapter without any problem using the same profile. Is there any problem or HW SW with the built-in TV WiDi adapter?
  How I check it? Is there anything else that I should put on TV?
  Please advice.

  Hello

  Intel WiDi software must be up-to-date.
  Here you can check if the driver and software update would be necessary:
  http://www.Intel.com/p/en_US/support/highlights/wireless/wireless-display

  Check Please also Intel WiDi Knowledge Base and troubleshooting page:
  http://supportkb.Intel.com/wireless/wireless-display/templates/selfservice/intelwidi/#Portal/1026/article/5858

  By the way: I recommend you to check the [Manual 40L7335D | http://www.toshiba-om.net/LCD/PDF/English/L7335-4050-English.pdf] page 46-47.

  There you can check if network TV settings have been defined correctly.
