任务栏闪烁？

[Zhanlixin]

1.首先我们在空白窗体中拖入一个NotifyIcon控件和定时控件
　　private System.Windows.Forms.NotifyIcon notifyIcon1;
　　private System.Windows.Forms.Timer timer1;
　　2.其次,我们准备两张ico图片,用来显示在任务栏,其中一张可用透明的ico图片,分别叫做1.ico和2.ico;并且建立两个icon对象分别用来存放两个ico图片;
　　private Icon ico1 = new Icon("1.ico");
　　private Icon ico2 = new Icon("2.ICO");//透明的图标
　　3.在Form_load中初始化notifyicon:
　　private void Form1_Load(object sender, System.EventArgs e)
　　{
　　this.notifyIcon1.Icon=ico1;//设置程序刚运行时显示在任务栏的图标
　　this.timer1.Enable = true;//将定时控件设为启用,默认为false;
　　}
　　4.先设置一个全局变量 i ,用来控制图片索引,然后创建定时事件,双击定时控件就可以编辑
　　int i=0;
　　private void timer1_Tick(object sender, System.EventArgs e)
　　{
　　//如果i=0则让任务栏图标变为透明的图标并且退出
　　if(i<1)
　　{
　　this.notifyIcon1.Icon=ico2;
　　i++;
　　return;
　　}
　　//如果i!=0,就让任务栏图标变为ico1,并将i置为0;
　　else
　　this.notifyIcon1.Icon=ico1;
　　i=0;
　　}

然后这么调用：

// Flash window until it recieves focus
FlashWindow.Flash(this);

// Flash window 5 times
FlashWindow.Flash(this, 5);

// Start Flashing "Indefinately"
FlashWindow.Start(this);

// Stop the "Indefinate" Flashing
FlashWindow.Stop(this);

“notification1.Text”闪烁的时候出现提示框。怎么去掉。

[捷哥1999]

不要设置notification1.Text看看，你是要在任务栏中闪烁窗口，还是闪烁托盘图标？

[denbes]

学习了.
1,用Notifyicon.
2,调用API
FlashWindow(IntPtr hWnd, bool bInvert);

任务栏闪烁，不设置的话仍然有提示。

[捷哥1999]

所谓的任务栏闪烁，就是指的，我们打开一个与好友对话的qq窗口后，如果有消息过来，就闪烁，对吗？

那你试试看我提供的代码，我的代码实现了那种方法。

如果你希望实现，没有打开qq对话窗口时，如果某个好友发来消息，在托盘区那里闪烁图标，那么就不要考虑我的方法了。

空白ICO与非空白ICO使用TIMER交替显示

学习了，帮顶！

一直以为是两个图片交替显示，原来还有api
