• How to change a global variable in a function?

  Hello

  I want to change a globalvariable in a function, as a first step I made in this way:

  class Global_output_class
  
  GlobalDim("Correlation_Status,fail_part,End_Exp")
  dim pouet
  
  Correlation_Status = 12
  Call Correlation()
  pouet = Correlation_Status
  
  Function Correlation()
    Dim Global_output_class_sub
    Set Global_output_class_sub = new Global_output_class
  
    Correlation_Status = 1
    fail_part = 2
    End_Exp = 3
  
    Global_output_class_sub.CorrelationStatus = Correlation_Status
    Global_output_class_sub.failpart = fail_part
    Global_output_class_sub.EndExp = End_Exp
    set Correlation = Global_output_class_sub
  End function
  

  In this case: correlation_status receives a value of 12, then I go to my correlationn() function where it became 1

  Then he comes out of the Sub-function and takes the previous value of the program (12) (I hate that)

  To solve the problem I did it this way:

  class Global_output_class
  public CorrelationStatus
  public failpart
  public EndExp
  end class 
  
  GlobalDim("Correlation_Status,fail_part,End_Exp")
  
  Correlation_Status = 12
  Set Global_Output = Correlation()
  Correlation_Status = Global_Output.CorrelationStatus
  fail_part = Global_Output.failpart
  End_Exp = Global_Output.EndExp
  pouet = Correlation_Status
  
  Function Correlation()
    Dim Global_output_class_sub
    Set Global_output_class_sub = new Global_output_class
  
    Correlation_Status = 1
    fail_part = 2
    End_Exp = 3
  
    Global_output_class_sub.CorrelationStatus = Correlation_Status
    Global_output_class_sub.failpart = fail_part
    Global_output_class_sub.EndExp = End_Exp
    set Correlation = Global_output_class_sub
  End function
  

  This way my global value are copied in themselves after leaving the subprogramme

  I had a lot of variables, is there an easier way for the global variable in a function of change keep the value after you leave the service?

  Thanks for the help,

  Fred

  Hi Fred,.

  It is possible to use a global variable defined, but the best way is to use a function call (or procedure call) with parameters. Please first find the right solution for a function call with parameter and the suboptimal way with a comprehensive valiable:

  dim oParameter
  set oParameter = new cGlobal_output_class
  
  oParameter.Correlation_Status = 12
  
  msgbox "Correlation_Status before Call Correlation: " & oParameter.Correlation_Status
  Call Correlation(oParameter)
  msgbox "Correlation_Status after Call Correlation: " & oParameter.Correlation_Status
  
  '-------------------------------------------------------------------------------
  Function Correlation(oPara)
    msgbox "Correlation_Status in the FUNCTION before change: " & oPara.Correlation_Status
    oPara.Correlation_Status = 1
    oPara.fail_part = 2
    oPara.End_Exp = 3
    msgbox "Correlation_Status in the FUNCTION after change: " & oPara.Correlation_Status
  End function
  
  '-------------------------------------------------------------------------------
  class cGlobal_output_class
    dim Correlation_Status,fail_part,End_Exp
  end class
  

  call GlobalDim("oPouet")
  
  dim oPouet
  set oPouet = new cGlobal_output_class
  
  oPouet.Correlation_Status = 12
  
  msgbox "Correlation_Status before Call Correlation: " & oPouet.Correlation_Status
  Call Correlation()
  msgbox "Correlation_Status before Call Correlation: " & oPouet.Correlation_Status
  
  '-------------------------------------------------------------------------------
  Function Correlation()
    msgbox "Correlation_Status in the FUNCTION before change: " & oPouet.Correlation_Status
    oPouet.Correlation_Status = 1
    oPouet.fail_part = 2
    oPouet.End_Exp = 3
    msgbox "Correlation_Status in the FUNCTION after change: " & oPouet.Correlation_Status
  End function
  
  '-------------------------------------------------------------------------------
  class cGlobal_output_class
    dim Correlation_Status,fail_part,End_Exp
  end class

• How to create a Global Variable through the Project Explorer

  Hello world!

  I know how to create a global variable (in a vi through the range of functions...).

  but I'm missing a way to create one via the Project Explorer.

  It's a missing feature or just this documentation (and the intuition of myself) are missing?

  It would be very convenient.

  THX for your time and hope that answers.

  jwscs

  Right click on my computer > new > new... > select Global Variable.

  EDIT: although I agree with Gerd (he probably wondering why you need so we can recommend a better way ), I rarely use them in easy to write once - read many applications such as security levels overall program at initialization (VER) to read later, but NOT modified.  I know it would be better to make a good class, functional Global Variable (FGV) or a motor Action (AE) but globals ARE practical and safe IF used wisely.

• Global variable in Oracle form 6i

  Hello
  
  How and where to set global variable in Oracle form 6i and also I would like to know how to access.
  
  
  Thanks in advance
  
  Kind regards
  Sanket

  Hello

  Global variable are variable specifice forms.
  It can store up to 255 for all uses character value.
  We can initialize when we declare otherwise give error if we has not assigned a value any.
  Oracle 10g, it can take up to 4000 bytes

  GLOBAL.ur_globalvar := TO_CHAR(15);
  
  or
  
  :GLOBAL.ur_globalvar:= '15';
  
  or 
  
  Remmber numeric values are implicitly converted by oracle 2 character
  
  :GLOBAL.ur_globalvar:= 15;
  
  -- which can then subsequently be accessed using...
  
  :GLOBAL.ur_globalvar;
  
  -- To destroy a global variable and release its memory, use the ERASE built-in procedure:
  
  Erase('GLOBAL.my_var');

• How to access a global variable that is common between the different baskets project library

  My project consist of several libraries, after generation the library project packed for each library, I find it cannot share data in a global variable between different packaged project library file. For example: packed project library #1 contains VI variables global wirte 'position' and give it a value '400 '. Library #2 present another VI project try to read this global variable, but he gave reading of is NULL not "400". Why has this happened? Is it possible to solve, welcome any help, I wll appreciate for this!

  If you understand what is happening here...

  When you build a PPL, it takes in the .lvlib and also all the dependencies of the .lvlib.

  In your case, when you generate the Test Task.lvlib in a .lvlibp, she also pulls on a copy of the DataProcess.lvlib:GlobalsVariable.vi because it's addictive to read GlobalVar.vi.

  When your application runs, you end up with two copies of GlobalsVariable.vi in memory:

  DataProcess.lvlibp:GlobalsVariable.vi

  AND

  Test Task.lvlibp:: GlobalsVariable.vi (I don't know how PPLs namespace dependencies... If there is still the DataProcess.lvlibp)

  Because they are different screws (i.e. in a different namespace), they have their own memory and that's why you can't access the data.

  Your Test Task.lvlibp calls the version of GlobalsVariable.vi, he pulled the dependencies.

  To solve this problem - you must ensure that Task.lvlibp of Test calls the version of GlobalsVariable.vi of the DataProcess.lvlibp - you'll need to replace all instances with the version of the PPL. Of course, if you run DataProcess in the development environment, then it will always be bad namespaced, hence the suggestion to put your global variable VI in is own PPL that you then use in the process of data and Test tasks.

• How to associate existing global variables

  It's probably something stupid that I'm missing.

  I created a global variable and there is a string.  I put it in a file called XML_Global.vi I then proceeded to make an another global var and would assign to the same variable.  However, the IDE shows me an another façade Globals 4.  How can I associate the existing façade of XML_Global.vi with the global variable I PLOPPED down there?  I looked everywhere on how to proceed in the properties and others, but couldn't find it.

  Have you read through this document?

  http://zone.NI.com/reference/en-XX/help/371361F-01/lvhowto/creating_global_variables/

  There may be some confusion about what is happening... When I add a global variable for the rough process, I followed the block diagram is:

  • Open the front panel to the global variable
  • Add FP (there may be several elements in a global variable VI)
  • Save the global variable VI
  • Then drag + drop of my project on a diagram VI
  • Select the variable I want by double clicking on the overall and will select an element > name Variable

  If this clears it for you? Looks like you try to simply place another instance of global variable in the palette of functions and then select the variable to assign this instance to (similar to what you would do with a local variable)? With globals, a new instance of a global VI is created when you drop the global BD... you want to place the world you have edited/saved (drag + drop of project or use the "Select" VI in the range of functions).

  I hope this helps...

• How to use the global variable in the table target?

  Hello

  I am trying to load several files into a single interface. the data is loaded successfully. 92. the files are there. for this I used variables and package.

  My requrement is 92 files of data loaded into the target table. I want to know what data from file.

  to this I added a column (filename) to the existing target table.

  If I used joints (not same condition), its totally wrong. all file names are coming.

  Please see the following screenshots.

  

  exit; target table.

  

  in fact in the target table. first 10 lines are coming from file.i.e first _ACCOUNT_LIMIT_511.TXT. but all the files names are coming.

  I'm confuse. After the first data file inserted then insert second data file. in that all file names are coming. Please help me.

  I thought that the global variable is preferable to identify the data came from which file.

  to do this, the global variable is used in the target table. I don't always have my exit.

  Please help me.

  Thanks in advance.

  

  Hello

  You can use the same way, how you use the project variable, just you have to do a thin is #GLOBAL.variable_name for example: #GLOBAL. SMART_AL_FILE_NAME_S

  Note: Make sure you that while you use one variable overall in interface, indicator should be staged as you chose above the screen

  hope this helps you

  Kind regards

• How to change the constant variable rate?

  Hello

  I export an HDV mpeg file that has a constant rate of a video H264 (.mp4) video for download on a web-based video player. I actually use the preset in Media Encoder 'YouTube HD 720 p 29.97'.

  The web interface of video online that I use requires a constant rate. But when you look at the video in MediaInfo it shows the video file as a variable rate. After looking through the settings in Media Encoder I found no option to fix this.  I see where you can change the frame rate and it is 29.97. So you might think, it would be constant but is not. And there is not any settings, I see, to change the constant variable. I don't see the flow settings, but this isn't the issue.

  I also have Apple Compressor and making a successful rate constant, but if possible I prefer to use Adobe Media Encoder. If anyone knows how to change this setting? Thank you

  Hi CLCTV,

  To close this thread, interpreted as variable rate exports are now interpreted as constant in the CC SOUL 2014 (8,0) and later. Please create a new thread if you are still having trouble with this problem.

  Thank you

• How to get the global variable for an instanceId

  Hello
  
  I have data in global variables of an instance level. And using that instanceId, how can I get the global-level variables data.
  
  Please me tips
  
  
  Thank you
  Sailendra

  Hello
  I guess you want to get the value of the external variable within the process. You can do like this:

  assuming that it is of type string. For other types of type cast properly...
  String extVarValue = (String) (New Component(instance: this)).get(attribute: extVarName);

  Replace "extVarName" with your project name. It returns the value of your project for the instance that you are currently working.

  -Thank you,
  Malar.

• How to display Global variable in the form

  Dear friends,
  
  I want to display the value of the global in the form as soon as the new form is opened.
  I used the display for this option but to fill this post, I have to at least run or insert the record.

  Manish,

  Assign the value to the global variable, the trigger of NEW-RECORD-INSTANCE of the block also. Then it will show.

• Is there a way to change all the variables of the form variables URLs?

  Is it possible to change or copy all the variables in the url, so they have a scope limited as variables of form with a single statement?

  For example:

  < cfset form.var1 = url.var1 >

  < cfset form.var2 = url.var2 >

  < cfset form.var3 = url.var3 >

  Is this possible with a single statement?

  Have you tried:

  OR

  I'm not 100% sure that you can add to the scope of the form like that in all versions of the CF.

  If not, you can work with a thrid variable that you incorperate both form and url variables in.  It is a common technique in the fuse box, I think.
