Hi there, exactly, Mark is right on this. You can use very COM object method as you use out of VBA for example.
I am working on a wrapper for a more "pythonized" access to the EXCEL API, you may have alokk on it as soon as it is published. BG Chris Am 29.11.2024 um 20:10 schrieb Mark Hammond:
It's been a while since I've done any of this, but I think there's an "xlApp.Quit()" method you can use? If so, then you might be able to break out of the look when "PumpWaitingMessages()" returns 1 - that will mean the message queue has received a WM_QUIT.

If I take the example of a very simple Excel automation, I tested two things. * Code1 below use pythoncom.PumpMessages() but I don't know how to stop it when the Excel is closing. I guess I should send a WM_QUIT message but I don't know how. * Code2 below use a while loop on pythoncom.PumpWaitingMessages() but once I stop the loop the COM server freeze as it is waiting for the messages it sends to be processed before closing. I guess I should pump all the remaining messages but I don't know how. Maybe I should use a totally different approach. Thanks a lot for your help.
