Still cant get it to work:

class CSampleDlg : public CFileDialog{
public:
    CSampleDlg(BOOL bOpenFileDialog,
    LPCTSTR lpszDefExt = NULL,
    LPCTSTR lpszFileName = NULL,
    DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
    LPCTSTR lpszFilter = NULL,
    CWnd* pParentWnd = NULL,
    DWORD dwSize = 0,
    BOOL bVistaStyle = 1){

    }
public:
    virtual void OnFileNameChange()override{

    }
};

Hi Thanks but I get an error when compiling this code:

class CSampleDlg : public CFileDialog{
public:
    CSampleDlg(){
        DoModal();
    }
public:
    virtual void OnFileNameChange()override{
        MessageBox(TEXT("Selection Changed"), TEXT("1"), 0);
    }
};

------------

The error is: 'CFileDialog' : no appropriate default constructor available

Mat:

You won't get a clearer error message than that. The CFileDialog
constructor needs parameters. Typically, you will give your derived
class the same parameters, and pass them on.
