Question

Hi I am making an application sort of like a mouse macro where when you press F it will move the mouses position between two spots, everything works the only issue I am running into is that I want this to work in the background as in when the form isnt pulled up on my screen. How can I do this? If anyone can help me that would be awesome.

private void Form1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.F)
    {
        PointConverter pc = new PointConverter();
        Point pt = new Point();
        pt = (Point)pc.ConvertFromString("60, 700");
        Cursor.Position = pt;
        System.Threading.Thread.Sleep(5000);
        pt = (Point)pc.ConvertFromString("600, 700");
        Cursor.Position = pt;
    }

事件仅在表单处于活动状态时才适用。您不能在后台使用表单中的事件。而是使用GetKeyState功能 https://msdn.microsoft.com/en-us/library/windows/desktop/ms646301(v=vs.85).aspx
看看虚拟键码也是如此。我做了一个应用程序，在后台监听按键一次。我必须在循环中使用GetKeyState来检查每个虚拟键代码以查看是否已按下它。但听起来像您的应用程序，您只需要检查您想要听的热键你需要在后台为你的循环运行一个线程，或者使用一个计时器。

CNC中这里有一些代码来实现GetKeyState函数。

[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern byte GetKeyState(int nVirtKey);
