Interesting ...

I tried it, but I got compiler-errors on PBM_SETBARCOLOR and PBM_SETBKCOLOR : Undeclared identifier.

Have I forgot to use one or more units ?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Hello!

This should do the trick:

First You Need To Add CommCtrl to your Uses clause, it contains the necessary message definitions

Code:
SendMessage(MyProgressBar.Handle, PBM_SETBARCOLOR, 0,clYellow);

Good Luck!

freshman3k , your code look alike mine. You just replace the color ( clRed with clYellow ).

wimmeyvaert, yes you must add CommCtrl unit . And then ...

procedure TForm1.FormCreate(Sender: TObject);
begin
  SendMessage(ProgressBar1.Handle, PBM_SETBARCOLOR, 0, MyColorHere);
end;

Works great ...
Hope alshepstone has the same meaning here.

Only
  SendMessage(ProgressBar1.Handle, PBM_SETBKCOLOR, 0, clRed);
seems not doing anything. I suppose this should color the background of the progrssbar. Maybe there it is better to do : ProgressBar1.Brush.Color := clRed;


Best regards,
The Mayor

Yes, I know, but in your second comment you placed

SendMessage(ProgressBar1.Handle, PBM_SETBKCOLOR, 0, clRed);

and I just want to let you know that this does not work, and that I think that 'ProgressBar1.Brush.Color := clRed'
is a good alternative.

Best regards,

The Mayor.
