本文介绍了一个使用C#实现的方法来自动选择EPSON R330系列打印机首选项对话框中的特定选项卡。通过调用Windows API函数FindWindowA和FindWindowEx来定位窗口和子窗口，然后使用SendMessage函数发送消息以切换到指定的选项卡。

        private  void SelectTab()
        {
            IntPtr hand1 = FindWindowA(null, "EPSON R330 Series 打印首选项");
            if (hand1 != IntPtr.Zero)
            {
                IntPtr hwnd11 = FindWindowEx(hand1, 0, "SysTabControl32", null);  // 
                int GW_CHILD = 5;
                int TCM_FIRST = 0x1300;
                uint TCM_SETCURSEL = Convert.ToUInt32(TCM_FIRST + 12);
                uint TCM_GETCURSEL = Convert.ToUInt32(TCM_FIRST + 11);
                UInt32 TCM_GETCURFOCUS = Convert.ToUInt32(TCM_FIRST + 47);
                UInt32 TCM_SETCURFOCUS = Convert.ToUInt32(TCM_FIRST + 48);
                int sss = SendMessage(hwnd11, TCM_SETCURFOCUS, 4, 0);
                int ssss = SendMessage(hwnd11, TCM_GETCURFOCUS, 4, 0);
                IntPtr hwnd111 = FindWindowEx(hand1, 0, null, "维护");  // 
                int controlId = 0xf43;
                IntPtr EdithWnd = GetDlgItem(hwnd111, controlId);
                int re = SendMessage(EdithWnd, 0xf5, 0, 0);
            }
        }
