There is no VB built-in function that can do arbitrary rotation. What you can do is to store the image pixel data into a two-dimensional array and then do the rotation transform yourself. Let me know if you need the formula for the transform. :)

Have a look at MSKB: http://support.microsoft.com/support/kb/articles/q186/2/60.asp
If you want me to post the code I will.

Note that the example rotates the bitmap in steps by 90 degrees, but it's rather easy to change it to rotate it any degrees you want to.
