Edit: Alright.
To draw a single point in visual basic:
Picturesurface.Fillrectangle(X1,Y1,1,1)
Picturesurface can be anything you declare as graphics. I just chose to use a picture.
Ie: Dim PictureSurface As Graphics = Me.PicName.CreateGraphics

I think it'd be more agreeable to keep the topic's question extant, and to edit the first post with your findings instead; that way, others can reference it later, because every post made in these forums has a strong likelihood of becoming a popular Google result. My two cents.

Alternatively, use a Bitmap and SetPixel.
If you are writing to lots of pixels at once, consider writing directly to the bitmap by storing the pixel data in an array then using Marshal.Copy to dump the data into the Scan0 of a BitmapData structure.
That probably makes no sense, but the names should be a hint and there's some old sample code here.
Note that GDI+ perfomance increases signficantly on Vista. If you are writing a program that targets XP and you need performance, consider using XNA or MDX to present your graphics to the display. |

| LOL. Well I guess that's what you get when you have spiders crawling through your website 24 hours a day. |
