    All i want is to make a forward reference to a class that inherits from CDialog Class.

    This is the class

    CClienteDlg : public CDialog

    All i want is to be able to create a reference pointer to the CClienteDlg to be able to call one of its methhoods from another class.

    The reason i cant just include the file is cause inclusion recursion. since both classes need to comunicate eachother.

    When i tried to to do the forward reference this way

    class CClienteDlg;

    extern CClienteDlg* DlgMain; // then i declare the global variable to the reference pointer

    But i get 2 errors:

    error C2065: 'IDD_Main_Dlg' : undeclared identifier


    error C2057: expected constant expression

    on this line

    enum { IDD = IDD_Main_Dlg };

    I been stuck in this for over a week =/, help is apreciated.
