发送GetAsyncKeyState()忽略的虚拟鼠标单击

本文关键字：虚拟 鼠标 单击 GetAsyncKeyState 发送 | 更新日期: 2023-09-27 18:26:08

我一整天都在试验和搜索，但我一辈子都不知道如何做到这一点。

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，因为我实际上按下了按钮，所以我想要的是mouse_event/GetAsyncKeyState（或一些我不知道的参数）的替代方案，这样我就可以在不影响实际状态的情况下操纵键状态。

例如，我已经能够在AutoHotkey中使用发送｛LButton up｝和GetKeyState（"LButton"，"p"）来执行此操作。

有什么想法吗？

MSLLHOOKSTRUCT包含LLMHF_INJECTED和LLMHF_LOWER_IL_INJECTED标志。也许你应该看看。

下面的代码只是一个带有计时器的空表单，配置为"On"并每隔几秒钟调用一次"TimerOnTick"。

当您点击时，输出为"497361，0"，当计时器点击时，输出是"4973611，1"
