In a VB.NET program I'm creating a new bitmap image, I then call Graphics.FromImage to get a Graphics object to draw on the bitmap. The image is then displayed to the user.

All the code samples I've seen always call .Dispose() on Bitmaps and Graphics objects, but is there any need to do that when neither have touched files on disk? Are there any other unmanaged resources that these objects might have grabbed that wouldn't be cleared by the garbage collector?

Wrap it in a using statement for the scope in which you need it. Then don't worry about explicitly calling Dispose()

Pseudocode:

using(new Graphics() = Graphics.FromImage)
{
     //Magic happens...
}
