Drawing Lines and Shapes

The first pair of coordinates (x1, y1) is optional. If you omit these coordinates, Visual Basic uses the object’s current x, y location (drawing coordinates) as the end point. The current location can be specified with the CurrentX and CurrentY properties, but otherwise it is equal to the last point drawn by a previous graphics or Print method. If you haven’t previously used a graphics or Print method or set CurrentX and CurrentY, the default location is the object ’s upper-left corner.
