Enumerate most top windows, list properties and get process
Posted: Tue Dec 16, 2008 12:16 am
This came about due to some code I needed for a program,
this is the test code that I initially made to try things out.
Hopefully someone else might find this interesting as well.
Find out all the "secrets" the windows in your system have.
Some parts of the source is commented out so that by running it as it is
you will only get windows with a window title listed, and the topmost window (as close to the root as it can find), then get the process id and fetch info like exe or filename name as well.
Some source is commented out so that only window properties with a actual property name is listed, the atom ones are not.
Those are usually temporary and can not be relied upon, but many of those named properties tend to be used again and again.
To get a property just use GetProp_() and to set a property (like for example add one to your own programs window9 just use SetProp_()
remember to use use RemoveProp_() if you use SetProp_() though to avoid memory leaks when closing your window.
Anyway, run, have fun peeking at what window properties all your systems windows have.
PS! If running on a limited user account you will most likely not see admin or any other high elevation windows, in that case running the your prog as admin might should do the trick and show you other windows.
Unless this is only limited to current desktop or session only, I haven't checked.
You'll have to redo the code though as I simply was lazy and used Debug for testing text output
