Hi!

You can try to set up the windows system and user settings (the values that users edit in the Control Panel/Display/Appearance form in thw Windows) by using the SystemParametersInfo API function temporarily before messagebox showin, than set the back to previous values. This way you will change the appearance of any messagebox in the system. Messagebox in the Windows is modal, so you cannot show it than change it appearance. Just do this before messagebox.

HTH.
