     Functions module for changing colors of the plain MS Progress Bar. There a a lot of these here on PSC, this one is a bit different as the demo application also includes a Code Generator. After you get the demo Progress Bar looking the way you want, enter your control name and click the "Generate" button. Then just copy and paste into your app. All you need to do is place the Progress Bar on your form, size it and set the min/max values, and the generated code takes care of it's good looks! Hope this is usefull for others.

'Set of functions to change colors of the stock
'(and plain) MS Common Controls Progress Bar.
'The fuctions are from a user control I did in 2003 for myself.
'But I found that I only used these functions most of the time,
'just changing the Foreground and Background colors.
'So why add "Code Bloat" with a user control when a few functions
'will do the job.
