如何让窗体最小化时只在任务托盘显示为一个小图标?并且鼠标右击小图标时能弹出菜单?^_^ 最好给出尽量简单一点的源程序,谢谢了。^_^<br>
 
比较简单的,下载一个CoolTrayIcon控件用(第三方的)。<br><br>想自己写的话,搜搜以前的帖子,这个讨论很多的。
 
留个地址,我给你发个程序源码
 
我也想知道.我的地址:sjj1226@sohu.com 先谢谢了.

可以去看看下面的控件<br><br>CoolTrayIcon &nbsp; <br><br>自动将Form缩小为TrayIcon,可设置MinimizeToTrayIcon为True,则Form最小化时不显示在任务栏上。<br>个人认为较RxLib中的RxTrayIcon好用,而且还有源代码哦!<br><br>新增加了些属性和方法,如BitMapToIcon方法可以将位图转换为Icon使用。此外,还添加了一个新控件<br>TextTrayIcon,它直接将文字作为Tray Icon,可以设置字体、颜色等,和Timer结合起来你就可以实现动态文字的TrayIcon了,这还是满酷的嘛:-)。<br><br>完整功能. &nbsp; &nbsp;源代码: 有 <br>适用于 CB3 CB4 CB5 D2 D3 D4 D5 D6 <br><br>设置几个属性就可以了<br>有例子程序<br>http://www.playicq.com/dispdoc.php?t=&amp;id=2508
 
to:Admy<br>你有没有应用的例子,发一个给我吧<br>&nbsp;metal@win88.net<br>谢谢了!
 
楼上的<br>http://www.playicq.com/dispdoc.php?t=&amp;id=2508<br>里面的就有一个好的例子呵
