framework自已带有一控件NotifyIcon，做起来很方便的。

[guoyangc]

使用控件notifyIcon，代码：
private void Form1_Load(object sender, System.EventArgs e)
{
//生成4个菜单项对象，显示文本分别为"显示窗口"、"隐藏窗口"、"执行程序"、"退出程序"
MenuItem menuItem1=new MenuItem("显示窗口");
MenuItem menuItem2=new MenuItem("隐藏窗口");
MenuItem menuItem3=new MenuItem("执行程序");
MenuItem menuItem4=new MenuItem("退出程序");
//分别为4个菜单项添加Click事件响应函数
menuItem1.Click+=new System.EventHandler(this.menuItem1_Click);
menuItem2.Click+=new System.EventHandler(this.menuItem2_Click);
menuItem3.Click+=new System.EventHandler(this.menuItem3_Click);
menuItem4.Click+=new System.EventHandler(this.menuItem4_Click);
//设置NotifyIcon对象的ContextMenu属性为生面的弹出菜单对象
notifyIcon.ContextMenu=new ContextMenu(new MenuItem[]{menuItem1,menuItem2,menuItem3,menuItem4});
//当用户双击程序图标时将执行相应的函数
notifyIcon.DoubleClick+=new System.EventHandler(this.notifyIcon_DBClick);
}

private void menuItem1_Click(object sender,System.EventArgs e)//“显示窗口”菜单的响应方法
{
if(this.Visible==false)this.Visible=true;//假如当前窗口没显示则显示当前窗口
}
private void menuItem2_Click(object sender,System.EventArgs e)//"隐藏窗口"菜单的响应方法
{
if(this.Visible==true)this.Visible=false;//假如当前窗口为显示的则隐藏窗口
}
private void menuItem3_Click(object sender,System.EventArgs e)//"执行程序"菜单的响应方法
{
//显示一个提示信息框，表示事件已经得到响应
MessageBox.Show("演示程序已经执行，此处功能就是显示一个提示框！","提示信息",MessageBoxButtons.OK,MessageBoxIcon.Information);
}
private void menuItem4_Click(object sender,System.EventArgs e)//“退出程序”菜单的响应方法
{
this.Close();//关闭当前对象(即窗体)
Application.Exit();//通过Application类的静态方法Exit()退出应用程序
}

private void notifyIcon_DBClick(object sender, System.EventArgs e)//用户双击应用程序图标进的响应方法
{
this.Visible=true;//显示当前主窗口
this.notifyIcon.Visible = false;
}

如果还不知道，再问。

NotifyIcon

private void notifyIcon_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
if ( miShow.Text.CompareTo( "显示服务器" ) == 0 )
{
Show();
this.Activate();
miShow.Text = "隐藏服务器";
}
}
private void FormServerMain_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
Hide();
miShow.Text = "显示服务器";
e.Cancel = true;
}

private void miShow_Click(object sender, System.EventArgs e)
{
if ( miShow.Text.CompareTo( "显示服务器" ) == 0 )
{
Show();
miShow.Text = "隐藏服务器";
}
else
{
Hide();
miShow.Text = "显示服务器";
}
}

NotifyIcon
form.visible=false时候
它.visible就为true
form.visible=true时候
它.visible就为false
然后给它的双击事件写方法探出菜单等，简单吧！
