Roger,

When attempting to compile your colorview example, it is missing the bdmslib.ch, which I assume is from Bobby, if he or you could share it would certainly be appreciated.

Thanks,
Rick

Oops. Probably should have finished that sample.

I asked Bobby if I could include it in the eXpress++ samples, but I tried working on it today to unbundle it from his stuff and it's going to take awhile to figure it out.

XbpColorDialog() is include in v1.9.355 SL1 "XppUi2.lib" but not documented
try this
