Win32::GUI

maybe some sort of IPC, like pipes? (i haven't played with it myself,
but that sounds like what you need...)

Look into the Expect module.  (note: I'm not positive it is implemented in
the Win32 environment - so forgive me if it is not..)

I'm trying to make a gui interface to a command-line program I have.  The 
problem is that at certain points, the program wants user input.  I tried 
backticks, but my script hangs at the point where the program wants input.  
Is there a way to interface with DOS so that when a DOS program wants input,

the control switches back to the Perl script, which can ask for input and 
then pipe that input into DOS?

Backticks, exec(), and system() all fail to allow for user input after the 
initial command.  Is there a module or something I can use for this?

a more windows-ish way might be to open a new window that instructs the user
to input "something" with a textbox for their input and an OK button to
accept, read in their input, and close the input window.

I'm trying to make a gui interface to a command-line program I have.  The 
problem is that at certain points, the program wants user input.  I tried 
backticks, but my script hangs at the point where the program wants input.

Backticks, exec(), and system() all fail to allow for user input after the

I looked into both these solutions.  I couldn't get Expect to work (I'll 
guess I'll have to wait for a Win32 version), and the problem with this 
other one is that DOS won't relinquish control back to the script until it 
has finished running - and since it's waiting for input, it never finishes.  
I discovered that I cam make it work if I use the console - DOS will wait 
for user input from the console, so you can enter it there.

I checked on the MSDN Library, and it seems that Windows starts an instance 
of a 'Virtual Machine' for each DOS prompt.  (This is to fool DOS into 
thinking it's the only thing running.)  What I need is some way to pipe info 
into and out of a VM - but I haven't found a way yet.  I've looked into 
pipes and threads and interprocess communication on the MSDN Library, but 
I've found nothing that works yet.

I've shelved this project for a while - I just applied for a job I'm very 
likely to get, so I won't have as much free time on my hands - and I'll get 
to write Perl!  (My last job laid me off - in fact, about 80% of their 
developers - a couple of months ago, but they had me writing PHP anyway.)  
Wish me luck!
