Par2: Getting Errorcode from ABC method 2004-06-07 -- Carl Sumner (In C55)
1. The Errorcode is often lost due to the Filemanager doing other
calls before returning.
2. There is another call that has a saved copy of Errorcode,
"FileManager.GetError".
3. The Filename is sometimes not filled in correctly. There is a
patch on this newsgroup for this.
4. If you use "Try" methods, as you should, you must Throw (show) any
other errors that occur or they will not be seen.
I use something like this:
-------------------------------------
RetVal = Access:HCOMINV.TryFetch(COM:NVITMidx)
IF RetVal = Level:Benign THEN
!Do something
ELSIF Access:HCOMINV.GetError() = 0 THEN !Msg:AbortReading
!Done, do something else
ELSE !Error
GlobalErrors.ThrowFile(Access:HCOMINV.GetError(),'Fetch Error on
HCOMINV')
ThisWindow.Response = RequestCompleted
ReturnValue = Level:Fatal
END
