This progra lets you draw, move, and delete line segments from a drawing. It’s a Visual Basic .NET version of the example Draw, move, and delete line segments in C# made by request.
Click and drag to draw line segments. If you click on a segment’s end point, you can drag it into a new position. If you click on a segment’s body, you can move the whole segment. Finally if you drag a segment onto the trash can icon, the program asks if you want to delete the segment.
See the original post for an explanation of how the program works.
