A strange question?

anhei1021

My program has the following errors? Looking for a master.
d:\visual c ++ program design and practice\myprint\myprintdlg.h (22): error C2065: 'IDD_MYPRINT_DIALOG': undeclared identifier
d:\visual c ++ program design and practice\myprint\myprintdlg.h (22): error C2057: expected constant expression
PrintView.cpp

The error line in the class CMyPrintDlg line 22 code is:
   enum {IDD = IDD_MYPRINT_DIALOG};

But the ID of my dialog is IDD_MYPRINT_DIALOG

The CPP of the dialog box does not include the header file of the application class (APP).

大明白

Is not including the resource.h file
