Wow. âWindowsâ is a pretty broad topic! (The purpose of the subject line is to attract those who are interested in the realm of your problem...)
Another tip (if I may): It would be better to use normal capitalization in posts (âVB
â not âvb
,â âI'mâ not âi'm,â etc.) It makes your posts easier to read, allowing more focus on what
youâre saying, without having to surmount how
youâre saying it.
There is an API, something like âEnumerateWindowsâ which gives you all of the windows that are open, tat is, that exist. (BTW: Thereâs never more than 1 active window...)
Having obtained the windows (you receive the contents of their title bar), you can then use the method of adding lines to a listbox with those data.
