[perl-win32-gui-users] DoEvents() warning

[Marcus <li...@wo...>]

I have a loop for a cancel button (as previously discussed) which uses
Win32::GUI::DoEvents(). Problem is, I'm getting unitialized value
warnings from Win32::GUI::DoEvents().

This is not a "show stopper", but I would like to know what DoEvents()
is expecting and how to return a value. If that's what it wants?

Thanks,

Marcus
