I've created a script in Python, which can run up to a minute. While my script is running I like to give the user a messagebox in windows7 that the script is running.
A possible thing is to display a Message when the script starts and to unload this message when the script is done.
Currently I use tkMessageBox in order to give some information. I also looked at ctypes.windll.user32.MessageBoxA, but couldn't find a solution.
