I'm just learning this, and I am working through these tutorials:

I haven't had to modify them much for VS2010 so far. Right now, (I think) I have created the dialog box, and the menu as a class and a resource, respectively. However, when I call
void MFC_Tutorial_Window::OnClickDialogNew()
    NewDialog dlg;
I get an error 'DoModal' : is not a member of 'NewDialog'
I suppose somehow I need to link the menu to the dialog box?

I believe I've added the references, included the libraries and essentially followed the instructions. Apparently I'm not very clear on how to make resources interact with new classes. Can anyone point me in the right direction?
Thanks very much!
