@DavidCrow : You are genius man .. Thankxx a lot .. As you said its just because of my Graphics driver . Earlier my graphics driver was not compatible with the hardware .. Now i have installed the new driver .. and the issue is resolved.. Thankxx again ..
But I want to get the text when it's pasted.
I checked WM_PASTE but it is send to the control that has the focus not it's parent CWnd.
My dialog has some control of buttons, edit boxes, list control, ...
so it is posible that any of these controls has the focus (when something is paste)
Check out these functions[^]. It's a while since I have done this but I'm afraid it is somewhat involved in terms of getting mutliple sets of information and matching the pieces together. Hey, if it wasn't Microsoft it wouldn't be fun.
One of these days I'm going to think of a really clever signature.
