发送被 GetAsyncKeyState() 忽略的虚拟鼠标点击？

我一整天都在尝试和搜索，但我一生都无法弄清楚如何做到这一点。

正如标题所示，我希望能够发送被 GetAsyncKeyState() 之类的东西忽略的鼠标点击。

基本上我在做什么：

//While physically holding left mouse button...
while (GetAsyncKeyState(0x01) != 0)
{
    //left mouse button virtually down (obviously already is down the first loop)
    mouse_event(2, 0, 0, 0, 0); 

    Thread.Sleep(100);

    //left mouse button virtually up
    mouse_event(4, 0, 0, 0, 0);
}

现在， while 循环停止了，因为我实际上抬起了按钮，所以我要求的是 mouse_event/GetAsyncKeyState （或一些我不知道的参数）的替代方案，这样我就可以操纵按键状态而不影响实际状态。

例如，我已经能够在 AutoHotkey 中使用发送 {L 按钮向上} and GetKeyState("LButton", "P").

有任何想法吗？

MSLL钩子结构 http://msdn.microsoft.com/en-us/library/windows/desktop/ms644970%28v=vs.85%29.aspx包含LLMHF_INJECTED and LLMHF_LOWER_IL_INJECTED旗帜。也许你应该看一下。

下面的代码只是一个带有计时器的空表单，配置为“On”并每秒调用“TimerOnTick”。

点击时，定时器计时时输出为“497, 361, 0”click输出为“497, 361, 1”
