Simple Question: XOR a Filled Rectangle? How?

This is embarassing to ask but i have no idea how to draw a filled rectangle in an XOR way into the DC.

I have my FillRect(hdc,&rect,hBrush) but when i try using the oldMode = SetROP2(hdcDesktop,R2_XORPEN); it does not XOR. According to MSDN it mentions that the filled interior should now be XORed but it isnt. Any ideas?

Thanks

I'm not familiar with this function so I may be totally off-base here, but the documentation seems to indicate that all SetROP2() does is set the mix mode so that subsequent uses of the pen will have the desired effect. It does not appear to be an immediate update function similar to FillRect().

Interesting. I didnt realize that. I hope there is a function to do what want then. I know i can bitblt but i dont want th eextra load of creating a bitmap, mapping to a compatible dc, doing a fillrect into that then bitblt'ing xor...too much for something that should be basic. Thanks for your heads up!

Hi again..I figured it out..I had to use the PatBlt function instead of FillRect(..) Thanks for your help
