faster

Hello forum, I have created a paint program, which I use with a SmartBoard to draw on. But when I draw, it reacts much slower than a usual Paint Program (MSPaint). I have a PictureBox which I draw on,to capture the mouse path. Every time the mouse is moved, the path is added to the "mousePath"...

I have made a program that makes and saves every possibility of characters under 7 characters (so far), and it takes about 10 mins to make one million possibilities... this is about 1800 possibilities per second (differering on different CPU's and RAM's) How can i make it more efficient...
