Hello Mario,

This is standard behaviour of ProgressBar control at the themed Win Xp.
Try to revise this control at the Classic Theme (similar to Win9x)

As Grigory said, themed XP and Vista applications, does ignore color messages for some controls.

IMHO, this is because MS wants that most controls colors being, theme colors.

I agree with this. I guess that non-theme colors should be used only in very special situations, when is really needed, if not, the interface becomes clumsy and confusing for the user.

Besides that, there is another issue that I've already commented:

You could, eventually 'paint' any control 'by hand' using a method called 'owner-drawn'.

The problem with it, is that the control appearance could become not consistent with the other (not owner-drawn) controls from a Windows version to another.

This currently could happen between Win9x apps and XP-themed/Vista-themed ones.

This is because I've avoided the use of 'owner-drawn' controls.

A clear example of this, is the tab control background.

In XP-themed apps it is filled with a color gradient depending on selected theme. having a background color for tab could give us an ugly an terribly inconsistent look.

Regards,

Roberto.

I didn't expect that I will need 'owner-drawn' method, but...
While working with my application, i need to create sample graph and I want to use progressbar to do it.

Where can I find sample about using owner-drawn method?
