Running SAS while Userform is Active/Shown

[Snox114]

Dear readers,

I'm having a problem with SAS when executing SAS in batch mode while a userform is active in Excel.

Is there any way to run the SAS in batch mode while a userform is active?
If not, is there any way to check when the 'batch APP' has completed its run and then re-open the userform?

I've tried the following :

• Creating an empty file from SAS as the last statement and then check in excel when the mentioned file exists (Using a loop);
• Userform.hide and userform.show in the same SUB;
• Using the waitonreturn with shell function in Excel (This executes the 'batch APP', but the score.sas code isn't executing);
• sApp = "SAS.Application"
  If IsAppRunning(sApp) = True
  
  Function IsAppRunning(ByVal sAppName) As Boolean
  Dim oApp As Object
  On Error Resume Next
  Set oApp = GetObject(, sAppName)
  If Not oApp Is Nothing Then
  Set oApp = Nothing
  IsAppRunning = True
  End If
  End Function;

I'll appreciate any help.

Thanks
