Hi..for some kind of reason my teacher is willing to pay me about 30$Big Smile for doing a tiny project for him in VB.NET 2003:

He wants me to get a fixed font name & size as input, and some chars, and the output will be the chars ordered by density.

So I thought what easy! :
for each char I will take a blank bitmap, fill it black,
draw the char in white, and count how many white pixels were drawn.

so I started a new windows form:


AND NOW, MY PROBLEM:
*  how can I draw text to a bitmap so that I can go over it's pixels ?
OR
*  how can I get pixels from a control (I drew on the control) ?
OR
*  how can I get pixels that were drawn by a controls getGraphics ?

I have done this in C# by creating a bitmap and assigning it to a control, therefore allowing me to use the methods specific to bitmaps. If I remember correctly it wasn't too hard. Try searching the Techoff I think I posted there.

did you mean this one
(no... what do you mean?)

I want to use drawing.graphics.drawString, and then to be able to get pixels from where it has been used...

okay, sorry for beeing such a noob with all the .NET stuff...
I think I have a solution..

I think if I use drawing.graphics.fromImage and then draw, it will change the image...let me check..[A]

EDIT:
yep, it worked - it updates the bitmap..
