Slow

I trie to fill out a PictueBox control (for example blue) with the Pset function, it takes days.
Can I improve the speed of that?

That is the code:

For x = 0 to PictureBox.Width-1
For y = 0 to PictureBox.Height-1
Pset (x,y) , 0
Next y
Next x

Use BitBlt. BitBlt has been explained millions of times on this forum already so I can't be botherd to type it all out again Go look for threads on BitBlt, it's easy enough to use.

Yep. Also there's some BitBlt samples on my website

...and especially in your case (to fill a picturebox) you can use the following code:

   'Fills Picture1 with blue pixels :D
   Picture1.BackColor = RGB( 0, 0, 255 )
