I've not used it myself, but I'd take a look at Win32::Process (standard
with ActiveState Perl), which has a Wait() method to allow you to wait
for a process to finish.
As an aside: ShellExecute() always returns once the process it is
launching has started. ShellExecuteEx() can give you a handle to the
started process, that you can then use to determine when it finishes.
But ShellExecuteEx() isn't implemented in Win32::GUI, so I think you'd
be looking at Win32::API to get this functionality.

Thanks for the idea! That seems to be more responsive, except that the
ShellExecute command doesn't block until Acquire exits. Is there a way
to make this block?

Subject: RE: [perl-win32-gui-users] system call delayed?
I'll include the handler and the scan function below, as both are
relatively short. Note that in the DoSCAN function, the scan button
(called $scan) is disabled right before the system call. When I
click the button, it is immediately disabled. So I know it's getting
to that point. But then it doesn't do the acquire call until I do
SOMETHING, ANYTHING else.
It might be worth trying the ShellExecute method rather than the perl
system command. See
http://perl-win32-gui.sourceforge.net/cgi-bin/docs.cgi?doc=reference-methods
This method is in Win32-GUI 1.02 and above I believe. Although it is
more "fiddly" than system, it's a direct interface into the win32 API
ShellExecute, and has most of the functionality. As ShellExecute is
associated with your window, it might solve your issue.
Cheers,
jez.
