add a button to save file dialog?

I'm wondering if it's possible to somehow add another button to the SaveFileDialog through APIs or whatever. I'm saving images and I want to have an "Options" button for specifying the image quality.... if not I'll have to show another form for that

I can't answer your question directly, but why don't you use the Save As Type combo box on the standard SaveFileDialog to list all the image qualities you support? The user would then select whichever one they wanted. I guess the file extension would be the same in each case, but that shouldn't be a problem.

Internet Explorer's Save As is probably closer to what you want, but I don't know how to do that in VB. NET.
