Determine window focus

[Ron W]

I'm trying to write a Perl script that will watch for an IE window to
get the focus, grab the COM2 input and output it as if it were from the
keyboard. When the IE window loses focus, it should sit quietly waiting
for IE to come back on top. We run a program that uses a bar code
scanner plugged into COM2 but I'd like to use the scanner to do input
on a web page, but it can't interfere with the other program. (on W2K)
I don't know where to start looking for the method to determine if a
window has focus. I looked through a lot of modules but came up empty.
Any help would be greatly appreciated.

Ron,

I would look at either Tk or Wx when dealing with GUI's and widgets. I am going through something similar on one of my own projects. You can follow my project at http://blog.cyberspacelogistics.com

I will be updating it this weekend with my findings.

Best Luck,
Jon
