使用SendMessage发送Alt+S

Question

怎样使用SendMessage发送Alt+S?

我的方法是

            SendMessage(hwnd2, 0x0104, 0x00000012, 0x20380001);
            SendMessage(hwnd2, 0x0104, 0x00000053, 0x201F0001);
            SendMessage(hwnd2, 0x0106, 0x00000073, 0x201F0001);

            SendMessage(hwnd2, 0x0101, 0x00000012, 0xC0380001);
            SendMessage(hwnd2, 0x0101, 0x00000053, 0xC01F0001);

完全按照spy++翻译的，但是发送之后，却不成功，spy++上却显示在每一条命令后多一个空发送，相当于

            SendMessage(hwnd2, 0x0104, 0x00000012, 0x20380001);

SendMessage(hwnd2, 0x0104, 0x00000000, 0x20380001);

            SendMessage(hwnd2, 0x0104, 0x00000053, 0x201F0001);

SendMessage(hwnd2, 0x0104, 0x00000000, 0x20380001);

            SendMessage(hwnd2, 0x0106, 0x00000073, 0x201F0001);

            SendMessage(hwnd2, 0x0101, 0x00000012, 0xC0380001);
            SendMessage(hwnd2, 0x0101, 0x00000053, 0xC01F0001);

这是什么情况？图片的上方是SendMessage的，下方是手动的。

感谢您的回答。

请问具体实现呢？能在后台，不激活目标窗口发送吗？

这就是一个API，构造你的参数 调用这个API就可以了：http://msdn.microsoft.com/en-us/library/windows/desktop/ms646310(v=vs.85).aspx
