Here is the crux of the class. You can change the implementation but it
should give you a good idea of how to handle it. Good call on getting
Mueller's book...it's a masterpiece.
Good Luck,
Bill

This is a restatement of an earlier post that evidently wasn't clear. I am
building a custom MessageBox dialog that has, among other things, a few
new button options (yes to all, no to all, etc.) and would like to make the
dialog look and act like the standard MessageBox. Therefore, I would like
to put in the message section the same type of icons found in the MessageBox
dialog, such as MessageBoxIcon. Exclamation. In another post here I had
asked about firing of sounds and it was suggested that I look at the book .NET
Framework Solutions, In Search of the Lost Win32 API by John Paul Meuller
for more information on rolling your own message dialogs. I have ordered
that book and it will be here in about a week. In the meantime, I thought
I would ask you guys how to put one of the standard MessageBox icons, such
as the exclamation icon, into my custom MessageBox dialog. Can someone tell
how that can be done?
Thanks,
Dennis
