Hello,

Please excuse a dumb, self taught (poorly) VB programmer who devises applications for educational use.

Here's my problem: I have a form on which I have drawn a graphic, at design time, using the line tool.

By using various buttons + slider the user is able to change the gradient of one of the lines and/or shift it to the right or the left. I've no problem with any of this.

But as the line is shifted to right/left and crosses other lines I get some very annoying and distracting flickering. It's as if each time the line moves incrementally all the other lines are redrawn. Is there some coding that I can use to prevent this?
