SendInput 函数怎么用

[谁学逆向工程]

我打开一个IE浏览器，把浏览器全屏，然后运行下面的代码，代表应该在左上角单击，然后浏览器窗口弹出系统菜单。但实际下面的代码没有任何反应

#include<iostream>
#include<Windows.h>
using namespace std;

void main()
{
	Sleep(3000);
	
	INPUT ip;
	ZeroMemory(&ip, sizeof(ip));
	ip.type = INPUT_MOUSE;
	ip.mi.dx = ip.mi.dy = 0;

	int a = SendInput(1, &ip, sizeof(INPUT));
	int b = a;

	Sleep(3000);
}

错开点位置试试，比如 ip.mi.dx = ip.mi.dy = 10;

没反应

[zgl7903]

ip.mi.dwFlags = MOUSEEVENTF_ABSOLUTE;

[zgl7903]

少了一个标志 ip.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE;

[zgl7903]

鼠标点击的操作 再增加相应的标志 MSDN上都有说明 MOUSEEVENTF_ABSOLUTE Specifies that the dx and dy parameters contain normalized absolute coordinates. If not set, those parameters contain relative data: the change in position since the last reported position. This flag can be set, or not set, regardless of what kind of mouse or mouse-like device, if any, is connected to the system. For further information about relative mouse motion, see the following Remarks section. MOUSEEVENTF_MOVE Specifies that movement occurred. MOUSEEVENTF_LEFTDOWN Specifies that the left button is down. MOUSEEVENTF_LEFTUP Specifies that the left button is up. MOUSEEVENTF_RIGHTDOWN Specifies that the right button is down. MOUSEEVENTF_RIGHTUP Specifies that the right button is up. MOUSEEVENTF_MIDDLEDOWN Specifies that the middle button is down. MOUSEEVENTF_MIDDLEUP Specifies that the middle button is up. MOUSEEVENTF_WHEEL Windows NT: Specifies that the wheel has been moved, if the mouse has a wheel. The amount of movement is given in dwData

INPUT ip;
	ZeroMemory(&ip, sizeof(ip));
	ip.type = INPUT_MOUSE;
	ip.mi.dx = ip.mi.dy = 10;
	ip.mi.dwExtraInfo = 0;
	ip.mi.mouseData = 0;
	ip.mi.time = 0;
	ip.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE | MOUSEEVENTF_LEFTDOWN;
	SendInput(1, &ip, sizeof(INPUT));

需要先把鼠标移动过去，然后再模拟点击，也可以这样：

POINT pt = {0};
	GetCursorPos(&pt);
	
	INPUT ip;
	ZeroMemory(&ip, sizeof(ip));
	ip.type = INPUT_MOUSE;
	ip.mi.dx = ip.mi.dy = 10;
	ip.mi.dwExtraInfo = 0;
	ip.mi.mouseData = 0;
	ip.mi.time = 0;
	ip.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN;

	SetCursorPos(10, 10);
	SendInput(1, &ip, sizeof(INPUT));
	SetCursorPos(pt.x, pt.y);

引用 9 楼 VisualEleven 的回复:

INPUT ip;
	ZeroMemory(&ip, sizeof(ip));
	ip.type = INPUT_MOUSE;
	ip.mi.dx = ip.mi.dy = 10;
	ip.mi.dwExtraInfo = 0;
	ip.mi.mouseData = 0;
	ip.mi.time = 0;
	ip.mi.dwFlags = MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE | MOUSEEVENTF_LEFTDOWN;
	SendInput(1, &ip, sizeof(INPUT));

你这个好使，但是有没有不移动鼠标的方法

我测试的可以啊

#include <crtdbg.h>

int _tmain(int argc, _TCHAR* argv[])
{  
  INPUT ip = {0};
  ip.type = INPUT_MOUSE;
  ip.mi.dx = ip.mi.dy = 0;
  ip.mi.dwFlags =  MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_MOVE; 
  
  if(SendInput(1, &ip, sizeof(INPUT)) != 1)
  {
    _ASSERT(0);
  }

  return 0;
}

CTRL + F5

你这个鼠标到是过去了，但是没出来菜单是怎么回事，单击应出来菜单啊
