Alan #1 / 3	how to let a global function pointer point to a function in a Class Something like that, extern void (get_frequency)( int oref, int l_frequency); class TuneDlg : public CDialog { public: TuneDlg(CWnd pParent = NULL); // standard constructor enum { IDD = IDD_TUNE }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support void GetFrequency( int oref, int l_frequency); DECLARE_MESSAGE_MAP() Quote: }; get_frequency=GetFrequency; I get a error, "can not covert void* to TuneDlg::*.

Roger Onslo #2 / 3	how to let a global function pointer point to a function in a Class you need to declare the get_frequency type as a pointer-to-member-function rather than pointer-to-function (they have different syntax and semantics). -- Roger Onslow Software Developer See my articles at http://www.codeguru.com See the product I am working on at http://www.swishzone.com "Operator .. give me the number for 911" ..

Javier #3 / 3	how to let a global function pointer point to a function in a Class Hi, declare GetFrecuency() as static member of TuneDlg: class Tu... { static void GetFrequency( int oref, int l_frequency); Quote: } then you can use everywhere using this syntax: TuneDlg::GetFrecuency(10,100); Quote: > > Something like that, > > extern void (get_frequency)( int oref, int l_frequency); > > class TuneDlg : public CDialog > > { > > public: > > TuneDlg(CWnd pParent = NULL); // standard constructor > > enum { IDD = IDD_TUNE }; > > protected: > > virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support > > void GetFrequency( int oref, int l_frequency); > > DECLARE_MESSAGE_MAP() > > }; > > get_frequency=GetFrequency; > > I get a error, "can not covert void* to TuneDlg::*.
