Hi Vel users,
I have a question. I need to subclass a window in VEL program (yes, I =
have a subclassing library wrote) to pick up custom events I need to =
program.
I would like to make a hidden window in an include file. Can I do this =
without having the id of the main form and can I use the ShowWindow =
command to hide the window in the include file before the main program =
opens (This is something like the hidden window in all VB programs)
Thanks!

If I understand you correctly... you want to define (ie. CreateControl) a
secondary window (form) in an include file and not have it displayed until
you're ready to? First, forms are not owned by any other control, so you
don't need to know the id of the main form to create a secondary form.
Second, forms are not shown until you execute the ShowForm command,
however, you shouldn't try to show the secondary form before the main form
(look at the example in Demo4.exw). So... if my suppositions are correct,
yes, you CAN do what you suggest.
Gary.

You may want to use GetWindowLong and SetWindowLong to subclass the main
form
