Hi!

Take a look to the MSDN manula and VFP samples. There are "BMP" files used and "MSK" files withthe same file name. While BMP contains real image, MSK file determines what parts of image are trasparent. This way you can completely get rid of parts you require to be the same color as toolbar. This is special useful, becasuse, event *if* you get desired result with playing around colors, changing appearance settings in Control Panel->Display might change color of toolbar and thus your buttons' background would be visible again. Just use MSK files to hide parts that require to be transparent.
