Can anyone tell me how to change this C# code to grab all instances of an
application that is running? Right now, it only will output to the first
opened single document interface application n times (n being the number of
the same SDI app running). My end goal is to be able to pass in a windows
handle and be able to get the appropriate application instance. I know this
might be a C# newsgroup question, but almost all of this code has been taken
from this newsgroup. If I get it to work, I will post source to here so
that all may use. This might be a stupid question, so if someone has a good
tutorial link they think might help me, I would be very grateful for this as
well. Thanks to anyone who takes a look!
