Visual Basic Reference
A Line control is a graphical control displayed as a horizontal, vertical, or diagonal line.
You can use a Line control at design time to draw lines on forms. At run time, you can use a Line control instead of, or in addition to, the Line method. Lines drawn with the Line control remain on the form even if the AutoRedraw property setting is False. Line controls can be displayed on forms, in picture boxes, and in frames. You can't use the Move method to move a Line control at run time, but you can move or resize it by altering its X1, X2, Y1, and Y2 properties. The effect of setting the BorderStyle property depends on the setting of the BorderWidth property. If BorderWidth isn't 1 and BorderStyle isn't 0 or 6, BorderStyle is set to 1.
