>I don't know about the native abilities of the program you use to bring up a graph on form. In my imaging applications I use image OCX which allows me to save any part of screen/window to image file (BMP or something else) and store it in general field.

Mr. Pikman & Founier:
can you give me an example of image OCX or a document?
whrer can i buy one or download it?
