As I said above, It does not work when changing Me.hWnd to Picture1.hWnd. See attachment.
And besides, you will see that when you alpha blend a form, the whole contents of the form alpha blends itself, even the title bar. What I want to be transparent is the background only, not the whole container and its contents. See the example code I posted a bit earlier in this thread. It makes any color of the form totally transparent, that is the effect I want but I want to see behind the PictureBox not through the form, see images above fo example. I've tried with the Picture1.hWnd methode but it does not work.
