Directly after the relevant function call.
For example:

//...
lv_ok := QP.LoadFromFile(Edit1.text, '');
lv_err := QP.LastErrorCode;       
if ( lv_err = 411 ) Then // File not found         
  begin
//...
Cheers,
Ingo

Is there an API that can give us a failed message when a method returned 0?  

There are some methods that returned 1 for success & 0 for error, they are 

   MergeDocument()
   LoadFromString()
   SetNeedAppearances()
   SetFormFieldValueByTitle()
   FlattenAllFormFields()

etc.

We would like to know why & see if the failed message give us hint on fixing the scripts that is causing the error.

Thanks.
