How to place MessageBox *always* in center of screen?

[Volkan]

It's obvious that calls to AfxMessageBox() always center themselves in the window object from where they are called, but can I change this behavior so that my calls to AfxMessageBox() are always in the center of the screen?

I guess I could create my own modal dialog class with a new constructor that takes a string argument (the error message). Is this the only way?

Thanks.
