RE: [perl-win32-gui-users] how do you read the contents of an edi t control?

My guess is that you pass the SendMessage function a copy of $ss, or the
contents of $ss, to be precise, so that whatever gets put in there will not
make it back to $ss. But if you pass \$ss instead, I would not bet on the
SendMessage function to know what to make of it. If it adheres to DWIM,
you're lucky.
