鼠标模拟器无需设置光标位置

问题描述

如何在不先移动光标位置的情况下模拟鼠标点击？



我有一个程序在前台窗口上执行鼠标点击，我在其中使用SendInput或SendMessage模拟鼠标左键单击。问题是，如果我将光标设置为点击位置将进行点击，但是如果我没有设置光标而不是没有点击发生，即使通过我传递x和y点。我想在不需要实际移动光标的情况下执行鼠标左键。



提前谢谢。

How to simulate mouse clicks without moving the cursor position first?

I have a program that perform mouse click on foreground window, in which I am using SendInput or SendMessage to emulate left mouse click. The issue is, that if I set cursor to clicking position will make the click, however if I don't set cursor than no click happens even trough I do pass x and y points. I would like to perform left mouse click without the need of actually moving the cursor at all.

Thank you in advance.

What I have tried:

[DllImport("user32.dll", SetLastError = true)]
        static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);

        [Flags]

            SM_CYSCREEN = 1,
        }
        [DllImport("user32.dll")]
        static extern int GetSystemMetrics(SystemMetric smIndex);

        public static void ClickLeftMouseButton(Point p)
        {
            INPUT mouseInput = new INPUT();
            mouseInput.type = SendInputEventType.InputMouse;
            mouseInput.mkhi.mi.dx = (p.X * 65536) / GetSystemMetrics(SystemMetric.SM_CXSCREEN);
            mouseInput.mkhi.mi.dy = (p.Y * 65536) / GetSystemMetrics(SystemMetric.SM_CYSCREEN);
            mouseInput.mkhi.mi.mouseData = 0;


            mouseInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTDOWN | MouseEventFlags.MOUSEEVENTF_ABSOLUTE;
            SendInput(1, ref mouseInput, Marshal.SizeOf(new INPUT()));

            mouseInput.mkhi.mi.dwFlags = MouseEventFlags.MOUSEEVENTF_LEFTUP | MouseEventFlags.MOUSEEVENTF_ABSOLUTE;
            SendInput(1, ref mouseInput, Marshal.SizeOf(new INPUT()));

        }
