我以前很喜欢Serv-U,自从它用Java重写之后我就再也没用过,实在是太慢了,我宁可用IIS搭建FTP,虽然IIS搭建FTP在权限管理上很不灵活。//playyuer@Microshaoft.cominvent
//一个TreeView的派生类:TreeViewEx完成NodeShowToolTip、NodeDoubleClick事务
//1.完成了NodeShowToolTip事务,分离键盘Ctrl键显现及设置ToolTipText
//2.完成了NodeDoubleClick事务,可在挪用中只呼应"叶子"节点
//3.点击TreeView空缺处不选中任何节点

感觉很多控件都必须自己去写代码;用了WebMatrix感觉也不是很好,毕竟没有很强的WYSIWYG效果。现在就不知道如何是好了。 |
