적당한 디렉토리에 압축을 해제 한후 visual studio 에 include 디렉토리를 등록하자.
위자드용 코드도 있으니 해당 visual studio 버전에 맞게 스크립트를 실행하여 등록하자.

Example

Basic Window

#!vim cpp (-)
class CMyWindow : public CWindowImpl<CMyWindow, CWindow, CFrameWinTraits>
{
public:
    DECLARE_WND_CLASS(_T("My Window Class"))
 
    BEGIN_MSG_MAP(CMyWindow)
        MESSAGE_HANDLER(WM_CLOSE, OnClose)
        MESSAGE_HANDLER(WM_DESTROY, OnDestroy)
        COMMAND_ID_HANDLER(IDC_ABOUT, OnAbout)
    END_MSG_MAP()
 
    LRESULT OnClose(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
    {
        DestroyWindow();
        return 0;
    }
 
    LRESULT OnDestroy(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
    {
        PostQuitMessage(0);
        return 0;
    }
 
    LRESULT OnAbout(WORD wNotifyCode, WORD wID, HWND hWndCtl, BOOL& bHandled)
    {
        MessageBox ( _T("Sample ATL window"), _T("About MyWindow") );
        return 0;
    }
};

#!vim cpp (-)
template <class T, COLORREF t_crBrushColor>
class CPaintBkgnd : public CMessageMap
{
public:
    CPaintBkgnd() { m_hbrBkgnd = CreateSolidBrush(t_crBrushColor); }
    ~CPaintBkgnd() { DeleteObject ( m_hbrBkgnd ); }
 
    BEGIN_MSG_MAP(CPaintBkgnd)
        MESSAGE_HANDLER(WM_ERASEBKGND, OnEraseBkgnd)
    END_MSG_MAP()
 
    LRESULT OnEraseBkgnd(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
    {
    T*   pT = static_cast<T*>(this);
    HDC  dc = (HDC) wParam;
    RECT rcClient;
 
        pT->GetClientRect ( &rcClient );
        FillRect ( dc, &rcClient, m_hbrBkgnd );
        return 1;    // we painted the background
    }
 
protected:
    HBRUSH m_hbrBkgnd;
};

#!vim cpp (-)
class CMyWindow : public CWindowImpl<CMyWindow, CWindow, CFrameWinTraits>,
                  public CPaintBkgnd<CMyWindow, RGB(0,0,255)> 
{
...
typedef CPaintBkgnd<CMyWindow, RGB(0,0,255)> CPaintBkgndBase;
 
    BEGIN_MSG_MAP(CMyWindow)
        MESSAGE_HANDLER(WM_CLOSE, OnClose)
        MESSAGE_HANDLER(WM_DESTROY, OnDestroy)
        COMMAND_HANDLER(IDC_ABOUT, OnAbout)
        CHAIN_MSG_MAP(CPaintBkgndBase)
    END_MSG_MAP()
...
};

Basic Dialog

#!vim cpp (-)
class CAboutDlg : public CDialogImpl<CAboutDlg>
{
public:
    enum { IDD = IDD_ABOUT };
 
    BEGIN_MSG_MAP(CAboutDlg)
    END_MSG_MAP()
};

#!vim cpp (-)
class CAboutDlg : public CDialogImpl<CAboutDlg>
{
public:
    enum { IDD = IDD_ABOUT };
 
    BEGIN_MSG_MAP(CAboutDlg)
        MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
        MESSAGE_HANDLER(WM_CLOSE, OnClose)
        COMMAND_ID_HANDLER(IDOK, OnOKCancel)
        COMMAND_ID_HANDLER(IDCANCEL, OnOKCancel)
    END_MSG_MAP()
 
    LRESULT OnInitDialog(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
    {
        CenterWindow();
        return TRUE;    // let the system set the focus
    }
 
    LRESULT OnClose(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
    {
        EndDialog(IDCANCEL);
        return 0;
    }
 
    LRESULT OnOKCancel(WORD wNotifyCode, WORD wID, HWND hWndCtl, BOOL& bHandled)
    {
        EndDialog(wID);
        return 0;
    }
};

CAUTION

_ATL_STATIC_REGISTRY 문제...
- WTL 7.0 을 써라... 문제없군...

 

    #define ATL ::ATL

    #include <atlapp.h>

    // other WTL include files...

    #undef ATL
