Window DC's

[coldfusion244]

I am attempting to teach myself DC's, these from what I understand can be anything from a window to a printer, monitor, etc. As an experiment to try and learn it, I want to grab the background image or color of the desktop and change it to some random color or colors. This is what I was thnking:

 

PseudoCode

Start

Grab hWnd

Grab DC

CreateBitmap

Toggle Bitmap Colors?

Write Bitmap to DC using BitBlt?

Release DC

End

[/Code]

 

Does that look like it'll work? I haven't used bitmaps before either, so hopefully it'll be a good learning tool. I am using Unmanaged C++.
