I am currently trying out Bernard’s shiny glass VFP buttons which utilize these classes. The form that will contain these buttons will also contain a background picture under the buttons. If I render these buttons using the default render mode of zero (memory BMP), then the surrounding areas of the button which accommodate the shadow show up and cover the background image. So, I changed the surrounding colors to be .Color.Transparent and tried render modes of 4 and 5 (memory/file PNG). This got the transparency to work perfectly, however the performance of the buttons as they get rendered (i.e. a new Draw() during MouseEnter and MouseLeave) is extremely slow.

Would anyone have any ideas as to how to get my performance back? The only thing I could think of right now is to save multiple PNGs to represent the button’s different states (default, hovered, and clicked) and just those for the events on a standard image control. However, I'd prefer just using the controls as designed with better performance.

Any assistance would be greatly appreciated.
