I have a Python application that will start up four notepad instances then send text to each one of them. I need to send text to all of these notepad instances in parallel, meaning at the same time. Currently the app only sends them in sequence, one at a time.
I will provide the source for this application, the only dependencies needed are pywinauto and sendkeys, both can be installed from easy_install. you can optionally use win32pdhutil to find the notepad pids instead of manually entering them.
This is a windows based application.
