invalid dialog template name at runtime

[Captrick458]

When I call a modeless dialog using something like

ptr=new MClass();
ptr->Create(IDD_PROGRESS,NULL);

NOTE: For this example, I have left out the error checking, etc.

I get a runtime error that amounts to an inability to resolve IDD_PROGRESS into a TemplateName. The actual error occurs with

if (!_AfxCheckDialogTemplate(lpszTemplateName, FALSE))

Any ideas would be greatly appreciated.
