模拟键盘输入 keybd_event()

找到需要的窗口，显示这个窗口到最顶层，把焦点给这个窗口，模拟键盘消息输入，隐藏这个窗口

附上虚拟键码值的网页 Virtual-Key 代码

 

以防累死也找不到某个符号的虚拟键值是多少，列一个函数

int a = VkKeyScan('A');

作用是得到一个字符的虚拟键值

 

    //找新的窗口

    strWindowTitle.Format(_T("xxxx"));

    }

    //默认的显示窗口
    ::ShowWindow(hCmdWnd, SW_NORMAL);
    //前端显示
    ::SetForegroundWindow(hCmdWnd);
    //窗口置顶
