I would like to display an icon of my app (in about box) and I am saving each byte I can. So I decided to extract this icon, but I don't know if it is better to take it from the app window (using SendMsg WM_ICON) or to extract it from the EXE file..

Can somebody tell me the dis/advantages of both methods. Or is other? Or it will be more economic to add a icon to the image component instead of writing code?
