error C2065: 'IDD_DIALOG1' : undeclared identifier

[d00ape]

How come I got the following error when including my dialog1.h file twice in separate files.
The compiler brakes at:

class CDialog1 : public CDialog
{
// Construction
public:
CDialog1 (CWnd* pParent = NULL); // standard constructor

// Dialog Data
//{{AFX_DATA(CADTTOSIMDialog)
enum { IDD = IDD_ CDIALOG1 }; // BRAKES HERE AND GIVES THE ERROR: error C2065: 'IDD_DIALOG1' : undeclared identifier
//}}AFX_DATA
…
};
…

This error is followed by the “error C2057: expected constant expression”

Thanks

It looks as though you have a typo somewhere

Check you have a definition for IDD_CDIALOG1 (which also has a space in in your code snippet, which will cause problems)

enum { IDD = IDD_ CDIALOG1 };

It might be supposed to be

enum { IDD = IDD_CDIALOG1 };

or

enum { IDD = IDD_DIALOG1 };

Go not to cats for advice for they will just walk over the keyboard
