Just create the dialog resource in the resource editor, then create a class for it in class wizard. Next, include the header for that class in your view class, then install a menu event handler in the view class for the menu item you want to launch the dialog from. In that event handler create a object of the dialog class and call .DoModal() something like:
CMyDialog dlg;
dlg.DoModal();
That's pretty much it.
