How to catch exception on report preparation ?

swierzbicki

Hello,

I have a problem : I don't know how to catch an exception during report preparation.
This code has no effect :

  try
    Result := frxReport1.PrepareReport();
  except
   on e: exception do
    Result := FALSE;
  end;

This is not important but I'm using Devart UniDAC fastReport component. In my case, an error is occurring while opening the Dataset. I have so far no option to catch this !

This is a workaround.

  frxReport1.PrepareReport;

  if ((frxReport1.Errors.Count <> 0)) then
    abort;

My problem is that report is still showing a dialogbox. Ins't there a property as "SiltentError" or "NoMessageOnError" ?

Try to set TfrxReport.EngineOptions.SilentMode to True and TfrxReport.EngineOptions.NewSilentMode to simSilent
