Question

我的程序将“Z”键绑定到激活计时器的处理程序。该计时器触发鼠标点击。

问题是，如果我按住Z超过5秒，它就会卡住而在KeyUp上它不会触发，变量不会变为false并且循环是无限的，所以它继续不再按下按键时触发计时器的回调。只有通过ALT+F4

才能阻止它

我使用globalKeyboardHook from here

代码的关键部分是：

 private void keyDownCallback(object sender, KeyEventArgs e) {
                    if (e.KeyCode.ToString() == "Z") {
                            timer1.Enabled = true;
                            this.forceNoLoop = false;
                    } else if(e.KeyCode.ToString() == "X") {
                            timer1.Enabled = false;
                            this.forceNoLoop = true;
                    }
            }

            private void keyUpCallback(object sender, KeyEventArgs e) {
                    timer1.Enabled = false;
                    this.forceNoLoop = true;
            }

            private void timer1_Tick(object sender, EventArgs e) {
                    if (forceNoLoop) return;
        mouse_event(MOUSEEVENTF_LEFTDOWN, (uint)Cursor.Position.X, (uint)Cursor.Position.Y, 0, 0);
        mouse_event(MOUSEEVENTF_LEFTUP, (uint)Cursor.Position.X, (uint)Cursor.Position.Y, 0, 0);
                    lblClickStatus.Text = "clicked " + (this.clickTimes++) + " times";
            }

所以问题是：如何解决冻结问题？

您可以在启用/禁用它之前尝试检查计时器的状态吗？

private void keyDownCallback(object sender, KeyEventArgs e) {
    if (e.KeyCode.ToString() == "Z") {
        if (!timer1.Enabled)
            timer1.Enabled = true;
    } else if (e.KeyCode.ToString() == "X") {
        if (timer1.Enabled)
            timer1.Enabled = false;
    }
}

程序冻结和定时器循环是无止境的
