gauge Lab Style

[sicag]

The control gauge Lab Style is redrawed badly when the control change value

[Al_S]

I don't have any problem redrawing the Lab Style gauge, whether the value is changing slowly or quickly (as fast as I can in a loop).
I'd check to make sure you have the latest driver for your video card.

It's not possible a problem with a video driver. I have the same problem on most PC with various SO (win2000, WinNT, WinXP). I tryed with a panel with a guage only and in this mode this control work fine. But with other controls or with two gauge one above the other the problem appear. I dont know where the problem is.

[Al_S]

Can you try this example with two gauges? Set a value or Spin the gauges and see how the gauges look. They look fine to me.

Your example work fine on my PC. I modify your example and this doesn't work. For modify it I must to disable the "Conform to System Color" option.
Thanks

The problem starts when you make the face of a gauge transparent. It does seem like a problem with the control. But there's a work around.
I found this tip from Thomas Deutscher here [broken link removed]<
/a>:
Use SetCtrlAttribute instead of SetCtrlVal. You may also need to call ProcessDrawEvents to update the screen.
See the updated example.
