發送由GetAsyncKeyState（）忽略的虛擬鼠標點擊？

Question

我一直在嘗試和尋找整天，不能爲我的生活弄清楚如何做到這一點。

隨着標題的讀取，我希望能夠發送被GetAsyncKeyState（）等東西忽略的鼠標點擊。

基本上我在做什麼：

//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); 
} 

現在，while循環停止，因爲我幾乎解除按鈕，所以我要問的是mouse_event/GetAsyncKeyState（或某些參數的替代方法我不知道），所以我可以在不影響實際狀態的情況下操縱關鍵狀態。

舉例來說，我已經能夠使用發送{LButton起來}和函數GetKeyState爲此在AutoHotkey的（ 「LButton」， 「P」）。

任何想法？

MSLLHOOKSTRUCT包含LLMHF_INJECTED和LLMHF_LOWER_IL_INJECTED標誌。也許你應該看看它。

下面的代碼只是一個帶有定時器的空表單，配置爲「開」，每秒鐘調用「TimerOnTick」。

當你點擊時，輸出爲 「497，361，0」 當定時器點擊輸出爲 「497，361，1」
