Hey
I have a form, and the user can doodle and do all kinds of stuff on it. However... I want to be able to invert the colour of the form. (its backcolour is white) And I don't wanna use the GetPixel; SetPixelV sorta thing, cause I already figured that one out and it takes yonks, and its way dodge 'ey...

If you know how to do it using BitBlt your a champ.. paste it here.

Oh n when u use bitBlt can the sourceDC and the DestinationDC be the same DC or do u need to make a copy of it to use as the sourceDC???

Thanx
