MessageBox.Show-- font change?
please check out my free to use FlexibleMessageBox which can be used instead of MessageBox and has a (static) FONT-Property.

Use a form with a Textbox and two Buttons OK, Cancel on it. Use this form instead of a MessageBox in the whole project. You can change the font, backColor, multiline etc of the textbox on the fly. You can change the size, color and font of the buttons too.
As far as I'm aware you can't, as the 'normal' dialog boxes are using your default system font settings.
Roll your own is probably the best way forward. It's fairly trivial to do, and much fun! And you can build in things that the standard dialog doesn't support (without PInvoke magic) such as centering in the middle of the screen etc.
