I whipped this up in response to finding and correctly identifying windows for process names. It's from my MSNStatus project. It is able to successfully identify the title of a window for a process under Vista, including Valve's Source based games/mods. Figured this might be handy to somebody else, I'm just glad I have it now. If anyone finds it particularly handy, I was thinking of maybe submitting it for official UDF inclusion to the next release of AutoIt. Lemme know. ;-)

Works good.

Simple, but effective

Keep in mind for _Process2Win() that it's almost guaranteed there will be more than one window associated to any given process.

These functions have already been created a few times, and we already have _ProcessGetName included with AutoIt.

This script picks only the most recently active & visible window, so it's likely to be more accurate in it's choice, however I have seen a few misfires.

Apologies, I didn't check the UDF list in the help file right away when I was writing this, I didn't think it would be there (lot of stuff I cooked up before wasn't there), but to be fair I did include other functions here. Only one of which is superseded by the function you mentioned. Edited May 20, 2009 by Cynagen
