@Divzed ,
In the dBASE newsgroups, we just had such a request of trying some code to do just this kind of thing, and as one of our more experienced programmers stated, it’s been difficult to do this kind of thing because the colors on the Windows Title bar, etc, are connected to the “themes” aspect and is diffiult to change without in depth knowledge, because as he pointed out, if you change that, you have to change everything related to it (window resizing, etc) because you’re intercepting and overriding the current theme with specific items in the UI, meaning, you now own the control of everything pertaining to it. He also pointed out that in the past, it may have been ‘relatively’ easier, but with Windows 11, the whole game has changed with regard that control.
Not being his caliber of programmer, I’m only able to relay the gist of his more technical explanation, but it’s something I wouldn’t even be tempted to attempt as I can’t see that kind of work just to change a color. Microsoft keeps making customization harder than it needs to be to just plug and place a color change, so it doesn’t appeal to me. :)
