Simple Newbie VB questions
Posted on 2006-11-03
Let me know if I need to brak these up into multiple question...
I am a newbie trying to finish off a project.
I am looking for a way to draw lines on a mschart in VB. When I type a value into a textbox I need a horizontal line to be drawn on the Y axis. If I type in a 2 I need (0,2) to be graphed, and so on.
How do I ensure that the data that can be inserted in a textbox are numerical values only.
