Is there a way to make a window like the Stay on Top window, but make it stay behind? For example, if you click on the desktop it does not come to the front. I would like to make a form that does the same thing: stays usable but from behind all other applications. I hope this makes sense.
What you’d have to do in this case is override the form’s WinProc method and intercept the WM_NCACTIVATE message. When you do that, you can set the message value to 0 and the form will not come to the top.
