I have the following problem in VB6 under winXP :

I want to set an icon for my C3PO toolbar buttton.
I use: Button.SetBitmap strIconFile, RESOURCE_ID .
Where strIconFile is a path to dll containing the compiled Res file.And RESOURCE_ID is bitmap resource ID.

The button is added Ok, but the icon displayed with the black background. I see my image but the background is black instead of transparent. I changed few different colors and settings, but nothing seems to help, the background is still black.

Could you please provide your comments about this issue ?

Best Regards.
