// algorithmically create dialog boxes as opposed to creating them in a resource file.
// The resource file method should be preferred, but that isn't possible for static libs.
// Example uses for this--custom asserts, custom exception handlers, d3d device selection.
// Basically dialog boxes you'd like to put into static libs and use in many projects
