C ++使用SetCursorPos在Windows中移动鼠标 [英] C++ move mouse in windows using SetCursorPos

问题描述

我创建了一个类似于wiimote的设备，我想在Windows中使用它作为鼠标（8.1）。
设备通过tcp连接到我的Windows计算机上的c ++ win32程序，并发送鼠标光标应该移动的位置。我使用SetCursorPos函数设置位置，这是伟大的控制大多数程序。但是当我尝试控制例如任务管理器时，光标不再移动了。当我从任务管理器切换回一些其他程序，它再次工作。我也尝试使用具有相同结果的SendInput函数。

I created a device similar to a wiimote and i want to use it as a mouse in windows (8.1). The device connects over tcp to a c++ win32 program on my windows computer and sends the position where the mouse cursor should move. I am using the SetCursorPos function to set the position, which works great to control most programs. But when I try to control for example the task manager, the cursor doesn't move anymore. When I switch from the task manager back to some other program it works again. I also tried to use the SendInput function with the same results.

这是我的代码看起来像SendInput：

This is what my code looks like with SendInput:

INPUT Input = { 0 };
Input.type = INPUT_MOUSE;

Input.mi.dx = (LONG)posX;
Input.mi.dy = (LONG)posY;

// set move cursor directly
Input.mi.dwFlags = MOUSEEVENTF_MOVE | MOUSEEVENTF_ABSOLUTE;

SendInput(1, &Input, sizeof(INPUT));

SetCursorPos只有一行：

With SetCursorPos it's just one line:

SetCursorPos(posX, posY);

任何人都能告诉我为什么它不适用于某些程序？

Can anybody tell me why it doesn't work for some programs? I know it has to be possible to do this, since I tried a smartphone app which controls the cursor and it worked in all programs.

推荐答案

我知道这是有可能做到的，因为我试过一个智能手机应用程序控制光标，

您不能设置光标位置或输入需要比程序具有更高权限的窗口。

You cannot set the cursor position or input of a window that required higher privileges than your program has..

如果您希望程序能够移动光标在任务管理器上，您需要与任务管理器相同的权限：管理员权限。

If you want your program to be able to move the cursor over task manager, you require the same privileges as task manager: Administrator Privileges.

这是在Windows 8 +上的操作。

This is how it is done on Windows 8+.

我尝试使用以下方法：

int main()
{
    HWND window = FindWindow("TaskManagerWindow", "Task Manager");
    if (window)
    {
        RECT rect = {0};
        GetWindowRect(window, &rect);

        SetForegroundWindow(window);
        SetActiveWindow(window);
        SetFocus(window);
        Sleep(300);
        SetCursorPos(rect.right - 200, rect.bottom - 200);
    }

    return 0;
}

当以管理员身份运行时，光标只移动任务管理器。它对于Windows 8+中的所有上下文菜单和窗口都是一样的。不只是任务管理器。

Cursor only moves over task manager when ran as admin. It is the same for all context menus and windows in Windows 8+. Not just task manager.
