How Do I Save A Portion Of A PictureBox?

VB6 or VB.Net?  (If .net, which version?)

Is ALL of the "picture" in the Image/Picture Property?...or is some of it being rendered "on top" in the Paint() Event?

- I use VB6.0

- Didn't understand what your trying to say.

Lets say that i loaded a picture into the picturebox1. Now all i want to do is to take a portion of that picture and save it on a second picturebox or to a .bmp file. How can i accomplish that?

You want the PaintPicture() method:

Something like:

    Picture2.PaintPicture Picture1.Picture, 0, 0, 50, 50, 100, 10, 50, 50

That would take the 50x50 portion at (100, 10) in Picture1 and paint it at (0, 0) in Picture2 within a 50x50 box.  Since the sizes are the same, this would be a straight copy and no stretching would occur.

I try to use
Picture2.PaintPicture Picture1.Picture, 0, 0, 50, 50, 100, 10, 50, 50

And i get invalid picture error message, why? Do i have to declare anything?
