Populating a card variable using SetVar

1-3BY4B3 Jun 8, 2010 12:31 PM

I am working towards creating a "paste as reference" routine using the API for our ECO/ECN procedure, and am becoming re-acquainted with VB programming. My first step was to simply pass the filename of a selected file to a variable on the card of the parent file (sounds simple right). The variables within my code all seem to work but the SetVar command doesn't populate the target card variable even when I hard code it. Portion of code below.

=================================================================

Dim vars As IEdmEnumeratorVariable8

vars = poCmd.mpoExtra

Dim VariantPath As Object

VariantPath = path

'vars.SetVar(VarName, "", VariantPath, 0

vars.SetVar("ECO_AffItem1", "", "New Value") 'Hardcode for test

System.Windows.Forms.MessageBox.Show(vault.GetWin32Window(poCmd.mlParentWnd),"Variable: " + VarName + "Populated With: " + VariantPath)

=====================================================================

Thanks

Hi, I have used the following in vb.net with some success. It is a public shared sub but doesn't have to be.

Public Shared Sub SetData(ByRef DestFile As IEdmFile5, ByVal MyVariable As String, ByVal MyVarVal As String)

' set variable in destination file

Dim varEnum As IEdmEnumeratorVariable8 ' declare enumerator
varEnum = DestFile.GetEnumeratorVariable ' set to destination file
varEnum.SetVar(MyVariable,"", MyVarVal) ' set variable
varEnum.CloseFile(True) ' close file

End Sub

you need to pass the file, then the variable name then the variable value.

hope this helps

Make sure you're calling Close() or Flush().

  Lee,
  
  I'll give that a shot, but I was under the impression that when accessing the data card and not the file directly that the CloseFile call wasn't required.

  Lee,
  
  Thanks, that was it. So apparently the help documentation is incorrect.
  
  IEdmEnumeratorVariable interfaces for folders are not affected and does not need a call to CloseFile. The same is true if the interface updates a file data card rather than the file iteself. (I.e. the interface was retrieved from the EdmCmd.mpoExtra variables in an EdmCmd_CardButton/EdmCmd_CardInput add-in call.

    Hi Guys,
    
    You'll notice that my code sample above does include the closefile call

      Thanks David. The reason I hadn't added it is unlike your code I am not accessing the file directly, rather I am changing the variable through the data card, which according to the help file shouldn't require the closefile call. Thanks for the snippet though in the event that I do need to populate the file directly.

    maybe in your case you did not need to call closefile but in other cases you will or you will get a
    E_EDM_FILE_SHARE_ERROR. I had no problems until I started processing DWG files.
