Hi,
Any idea on how to create a transparent window? I am kind of stuck with
this for a while now...
From: Vikky on 29 Mar 2008 21:22

I have been able to display a transparent window using HOLLOW_BRUSH. But,
now the problem is that I am drawing into a region of the window when there
is input from the user. I am not able to erase the background for drawing the
new text. I have tried copying the DC before drawing, keeping it in memory
and then when I have to redraw bitblting into this region. But, this doesn't
work. Any idea on how to go about it?

Sorry, but no you haven't. You've created a broken window
that doesn't properly repaint itself.

About the only thing you can do is use GetDC(0)/BitBlt() to copy the
desktop to a private buffer before your window is drawn. Then draw this
private buffer onto your window during WM_PAINT.
