C#采用mouse_event函数实现模拟鼠标功能
2021-06-21 16:03
标签:value .net ptr com 修改 syntax ati cli 单击 下面我通过代码为大家分享下C#模拟鼠标,具体内容如下: 想必有很多人在项目开发中可能遇见需要做模拟鼠标点击的小功能,很多人会在百度过后采用mouse_event这个函数,不过我并不想讨论如何去使用mouse_event函数怎么去使用,因为那没有多大意义。 鼠标点击目标时会向鼠标所点击目标窗口投递消息,根据鼠标的按键、状态不同会投递不同的消息,一个完整的“鼠标左键单击”事件过程为“WM_LBUTTONDOWN + WM_LBUTTONUP”即鼠标“先左键按下 + 后左键抬起”,由于mouse_event可以模拟鼠标点击过程而不是直接性一次完整的鼠标单击过程,所以同样存在“按下、抬起” mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP | MOUSEEVENTF_MOVE, -450, 0, 1, 0); edit_position函数主要用于对MOUSEEVENTF_MOVE于MOUSEEVENTF_ABSOLUTE 相对/绝对光标位置修改的一个支持 send_message函数主要用于模拟鼠标点击的过程,上面我提到“先左键按下 + 后左键抬起”在上面的代码中你会看的清楚的不得了,如果相反你可以去尝试一番会有什么后果与其说 不如你们自己做更要来的快些。 鼠标左键双击(静默): 鼠标移动(相对位置): 鼠标移动(绝对位置): 以上内容比较多请认真学习,希望能够帮助到大家。 C#采用mouse_event函数实现模拟鼠标功能 标签:value .net ptr com 修改 syntax ati cli 单击 原文地址:https://www.cnblogs.com/ssslgf/p/10231331.html

上述代码你发现了什么?如果你发现说明你知道了本文到底在写什么东东 说不定你会有一些兴趣看下去,不过想到我如今混那么凄惨 在工地上做干活 不过也还好。
mouse_event在没有提供MOUSEEVENTF_MOVE量时光标不会移动到相对位置,“光标相对位置=光标现行位置+新光标位置”如果提供量“MOUSEEVENTF_ABSOLUTE”绝对位置,则会以“新光标位置”为准而不会添加“光标现行位置”

SetCursorPos(dx, dy);

}

Abs(

{
return

}
MakeDWord / 合并整数,函数主要是把两个
short
合并为一个
int
,分为low、high两部分

Point lpptPos =

if
((bRetVal = ScreenToClient(hwnd,
ref
lpptPos)))
{
x = lpptPos.X;
y = lpptPos.Y;
}
return
bRetVal;
}
screen_to_client函数故名思意,它主要用于把屏幕上的坐标转换到窗口客户上对应坐标
