Well, not given the way CW_FSLIDER is written. But a couple of well-placed _EXTRA keywords would probably make a five minute job of it. But I would ditch the "graphical creation tool", too, while I was at it. You won't learn anything but bad habits if you write your code with that. :-) (It's true that you can write awful widget programs by hand, too. But at least if you do, you have a better chance of fixing them.)

We all know that, but most of us ignore it and go to work anyway, just because we love him so. :-) Cheers, David -- David W. Fanning, Ph.D. Fanning Software Consulting, Inc.
