单击和双击的委托不好使了,是不是与我使用了多线程有关系呢?请多线程高手指点......

}
}

private void m_NotifyIcon_Click(object sender, EventArgs e)
{
this.m_flash = false;
this.m_NotifyIcon.Visible = false;
} }
}完全代码如上,单击和双击都委托到最后面这个方法里了,但是调试时进入不了

Answer 1

加个断点，看看m_NotifyIcon.Click+=new EventHandler(m_NotifyIcon_Click);
m_NotifyIcon.DoubleClick+=new EventHandler(m_NotifyIcon_Click);
这两句话有没有运行。应该不是多线程的关系。

Answer 2

运行了,但是在命令窗口里 查看,如下:
this.notifyIcon1.Click
错误:“this.notifyIcon1.Click”不存在

Answer 3

this.notifyIcon1.Click
为什么提示信息是notifyIcon1
而不是这个m_NotifyIcon呢。我在你的代码里面确实没有找到这个东西啊。

Answer 4

change 
m_NotifyIcon = new NotifyIcon();with
m_NotifyIcon = new NotifyIcon(this.components);

Answer 5

必须把m_NotifyIcon 加到该程序组件中去
