[alr1976 0]

Hi ,

I Need to handle exception in parallel.foreach because i Need to check for each task i got problem. I tried:

parallel.&Foreach(0,1)
  .TaskConfig(parallel.TaskConfig.OnTerminated(
  procedure(const task: IOmniTaskControl)
  var
   excp: Exception;
  begin
  if assigned(task.FatalException) then begin
   excp := task.DetachException;
   outvatinfo.Lines.Add('Caught async exception '+excp.ClassName+':'+excp.Message);
   FreeAndNil(excp);
  end;
  end))
  .Execute(
       procedure(const value: integer)
       begin
        
        raise Exception.Create('Exception in Async');
        //strtofloat('&');
        

   // outvatinfo.Lines.Add(datetimetostr(now())) ;
       end);

 

 

But It crash....

 

Someone can help me?

Thanks Alessandro

To quote "the book":

 

Quote

3.12.9 Handling exceptions

ForEach abstraction does not yet implement any exception handling. You should always wrap task method (code passed to the Execute) in try..except if you expect the code to raise exceptions.

Not an answer, but I'm just curious: why &Foreach? AFAIK, foreach is not a keyword.
