Bitblt to other forms

I have a problem (actually, it's really two)
I am trying to bitblt pictures from one from to another. Is this possible, and if so does this mean you have to include stuff like "Form2.picture1.hdc"???
Also, when I try to Bitblt any pictures that aren't visible (or out of screen, I can't copy all of them. Is there a way to fix this???

To BitBlt from one form to another you've to specify the full "path" to the Picturebox, so ;

Blit from ; Form1.Picture1.hDc
Blit to ; Form2.Picture1.hDc


Regarding blitting images that arent visible etc, you should use memory DCs instead really

Try setting the AutoRedraw on those "invisible" pics to true.
