What you want to do is difficult, however it is possible. You need to hook into the messagebox before it appears. Then you will need to use the CreateFont() and SendMessage() API calls. With SendMessage you would be using WM_SETFONT. In any event, if you wanna have a go at doing this then you could use the FLL and example code that I provided on my blog sometime back to get started (will take out most of the grunt work for you).
