我正在使用Microsoft Visual Studio在C#中创建一个简单的应用程序。
应用程序使光标移动到一个点(窗体外窗口)并单击多次。我按下X开始点击循环。所以如果你感兴趣,代码看起来像:
public void Wait(int milliseconds)
{
System.Threading.Thread.Sleep(milliseconds);
}
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);
public const int MOUSEEVENTF_LEFTDOWN = 0x02;
public const int MOUSEEVENTF_LEFTUP = 0x04;
public const int MOUSEEVENTF_RIGHTDOWN = 0x08;
public const int MOUSEEVENTF_RIGHTUP = 0x10;
public void MouseClick(Point pos, int click = 0)
{
int x = pos.X;
int y = pos.Y;
//MessageBox.Show("clicking mouse on " + pos.ToString());
if (click == 1)
{
mouse_event(MOUSEEVENTF_RIGHTDOWN, x, y, 0, 0);
mouse_event(MOUSEEVENTF_RIGHTUP, x, y, 0, 0);
}
else
{
mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0);
mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0);
}
}
public void MouseMove(int x, int y)
{
MouseMove(new Point(x,y));
}
public void MouseMove(Point target)
{
Cursor.Position = target;
}
private void Form1_KeyUp(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.A)
{
MessageBox.Show(Cursor.Position.ToString());
}
MouseMove(42, 42);
if (e.KeyCode == Keys.X)
{
MessageBox.Show(Cursor.Position.ToString());
Wait(42);
Random r = new Random();
for (int i = 0; i < number_of_times ; i++)
{
Wait(r.Next(42));
MouseClick(Cursor.Position);
}
}
}
但是,正如您所看到的,一旦点击开始,表单就会返回(在屏幕中看不到),因此无法检测到按键。那我怎么能停止点击循环呢?如果我按Ctrl + Alt + Del,它会暂停,然后我打开任务管理器,但点击继续。
也许有办法检测ctrl alt del?当窗口关闭时,还是任何其他按键?
感谢您的帮助!
