使用子类化技术，让 对话框中的 Edit 控件接受 TAB 键（纯属抄袭MSDN）

 

The following example shows how to subclass an instance of an edit control in a dialog box. The subclass window procedure enables the edit control to receive all keyboard input, including the ENTER and TAB keys, whenever the control has the input focus.

WNDPROC wpOrigEditProc; 
 
LRESULT APIENTRY EditBoxProc(
    HWND hwndDlg, 
    UINT uMsg, 
    WPARAM wParam, 
    LPARAM lParam) 
{ 
    HWND hwndEdit; 
 
    switch(uMsg) 
    { 
        case WM_INITDIALOG: 
            
            hwndEdit = GetDlgItem(hwndDlg, ID_EDIT); 
 
            
            wpOrigEditProc = (WNDPROC) SetWindowLong(hwndEdit, 
                GWL_WNDPROC, (LONG) EditSubclassProc); 
            
            
            
            return TRUE; 
 
        case WM_DESTROY: 
            
            SetWindowLong(hwndEdit, GWL_WNDPROC, 
                (LONG) wpOrigEditProc); 
            
            
            
            break; 
    } 
    return FALSE; 
        UNREFERENCED_PARAMETER(lParam); 
} 
 

LRESULT APIENTRY EditSubclassProc(
    HWND hwnd, 
    UINT uMsg, 
    WPARAM wParam, 
    LPARAM lParam) 
{ 
    if (uMsg == WM_GETDLGCODE) 
        return DLGC_WANTALLKEYS; 
 
    return CallWindowProc(wpOrigEditProc, hwnd, uMsg, 
        wParam, lParam); 
}
