HD33258: INITIALIZE FAILS WHEN CALLING CATVBA FROM CATSCRIPT OR CATVBS

APAR status

• Closed as Permanent restriction.

Error description

• Initialize fails when calling a catvba from a catscript
  or a catvbs (using ExecuteScript of SystemService).
  Scenario:
  The first time that a catvba is called by a catscript
  or catvbs in a
  CATIA V5 session, Initialize method for vba user
  forms fails.
  Scenario:
  - Copy the following files in D:\Temp folder
  o PMR.CATScript
  o PMR.catvba
  o PMR.catvbs
  If D:\Temp is not available, copy the files to an
  another location and
  modify the following line in the catscript and catvbs
  with the
  appropriate path:
  call CATIA.SystemService.ExecuteScript
  ("D:\Temp\PMR.catvba",CatScriptLibrary
  TypeVBAProject,"PMR1","CATMain",params)
  1 -> Catvba by itself
  - Start CATIA (make sure to clear your
  CATSettings prior)
  - Tools/Macro/Macros Macro library
  - Select VBA projects
  - Add existing library...
  - Browse for D:\temp\PMR.catvba
  - close
  - Select PMR1
  - Click Run
  You should see the following panel:
  see attached doc
  If you click on the button, you should see this:
  see attached doc
  There is no problem
  2 -> Catvba called by CATScript
  - Start CATIA (make sure to clear your
  CATSettings prior)
  - Tools/Macro/Macros Select
  - Browse for D:\temp\PMR.CATScript
  - Click Run
  You should see the following panel:
  see attached doc
  If you click on the button, nothing happens.
  There is a problem.
  Note that the next time you launch the CATScript
  there is no problem
  (until you restart CATIA).
  3 -> Catvba called by CATvbs
  - Start CATIA (make sure to clear your
  CATSettings prior)
  - Tools/Macro/Macros Select
  - Browse for D:\temp\PMR. catvbs
  - Click Run
  You should see the following panel:
  see attached doc
  If you click on the button, nothing happens.
  There is a problem.
  Note that the next time you launch the catvbs there
  is no problem
  (until you restart CATIA).
  Expected behaviour: Initialize method should
  always work.

Problem conclusion

• THIS PROBLEM IS PERMANENT RESTRICTION IN
  CATIA.
  Incident Diagnosis :
  A VBA Form launched from a VBSCript macro
  through the CATIA.SystemService.ExecuteScript
  method does not raise events the first time is is
  executed (the buttons do not respond). This
  scenario works OK on the next replays.
  Restriction Explanation  :
  The Microsoft VBA code seems to have a problem
  in initialiazing the VBA events handler when we are
  in the VBScript thread. As this problem is specific
  to the Microsoft code, we cannot find a solution a
  have to close this issue Permanent Restriction.
  By-Pass :
  A bypass consists in writing a VBA macro instead of
  a VBScript macro to do the
  CATIA.SystemService.ExecuteScript method call.
  As this scenario already uses a VBA form
  (which is not supported on Unix), this is useless
  using VBScript and using VBA would
  be more coherent.
