[AccessD] Visual Basic 2012 - Simple Gauge Tool

[Dan Waters]

Those horizontal gauges with the thin vertical line are nice!  However, I
would change the entire color of the bar according to what the % value is.

Paul,

You may find some ideas in this article from Bacon Bits.

I haven't used the technique but I have read it in articles.
Cheap, simple... maybe too simple.
Good luck.
