Don't you guys find it tedious typing the same thing
after your signature each time you post something?
I know I do, but when in Rome...

Do you kmow a similar function to DoEvents used in VisualBasic
for Borland Delphi?
The idea is to attend the events happening during a loop
execution.
Thank you very much in advance,
Miguel

This is what I use. Its construction isn't obvious due to the on-line help
but it does seem to work:
procedure doEvents;
begin
if Application.Terminated then abort;
Application.ProcessMessages;
if Application.Terminated then abort;
end;
The first "if" checks to see if we've already received a WM_QUIT message; if
so we do not want to "eat" it. The second "if" checks to see if the latest
message received was WM_QUIT; if so we want to bail out pronto.
Personally, I find the resulting routine a little confusing but I just added
it to my project-wide utilities module and moved on.

>>Dear colleagues,
Just a question, why bother with making your own DoEvents Proc when
you could just call the Application.ProcessMessages. I just use it
plain vanilla with out the extra if's and have never had any problems.
Am I missing something?
