像这种数据嵌套的操作用存储过程是最好的，别的没办法

注意PrepareCommand这个函数 ...,out mustCloseConnection)
所以正常路径是会关闭的。

关于12楼说的，动态添加item的DropDownList取不到选择值，我也碰到了，但琢磨了一阵子，明白了是什么问题。
动态添加item的代码，必须用IsPostBack了判断是否执行，否则每次某个事件提交后，添加 item的代码段会再次执行，然后selectedindex又会被置到0了。
修改后，添加了IsPostBack的判断，就能取出选择值了。

丫的，无意中看到JL.ZHOU的大作!Aha~

晕,乱讲,这个是在windows上开发调试然后可以部署在linux上

@怪怪:

分析得到位！是我看到的关于CS的最可观的评价！高手！

强调一下Release版本和Debug的性能区别....，如果你的程序在Release版本和Debug版本上没有明显的性能差异，说明你的程序纵深太小，除了在水平面延展，基本没什么结构可言 -___- 。不幸的是，大多数所谓"php的环境下面大型的b/s框架比比皆是，而且速度奇快"如果将其一一对应到ASP.NET，基本都是这种水平，所以比起来CS，尤其是Debug时简直惨不忍睹~~ 而大多数Web应用，由于其需求相对固定，所以根本没有必要使用OO的设计方法。不幸的是CS的作者不太明白这一点，固执的以为只要懂得性能调优就一切摆平...，且不说他对OO设计的使用除了一个Provider，其实不那么到位..

刚才又试了下Release版本，其实响应真没记忆中那么差，但对于咱们开发人员来说，大多数时候面对的是Debug版本，比Release后慢百倍的速度，确实跟噩梦一样。毕竟CS在国外部署了不少，哪个也不比Discuz流量小，说它性能多差(尤其是多用户并发的状况下)，也不太可能，否则早被淘汰了。

全是ASP.NET。按某比Alexa专业点的统计，全球流量前6中的四个全是ASP.NET，只有Yahoo和Google不是。CS确实超慢，主要在于控件包装太多，优化不足。另外一点，如果是Release版本，而且你访问的页面在一段时间内不是第一次访问，其实速度比想象中好。另外，随着流量增大，响应速度比那些显得非常快的轻量级ASP.NET/JSP/PHP程序下降的慢。

至于php这种动态语言与静态语言比效率，php简直没有性能可言。不信你看那篇著名的如何用php挣一百万的php优化文章中的数据，然后自己在ASP.NET实现一个同样规模的例子，和它保持同样的优化水准的情况下，看看效率。

我个人也觉得CS的缓存机制还有换肤机制做的都不怎么样，性能也不够好。不知道新版的CS2007有没有什么大的改进？

我租的国外的空间，速度很快的呀？

这程序臃肿且速度奇慢

说实话 感觉 CS 并不太适合国人使用...

速度还好吧

我用cs21sp2的做了一个系统，所以很多方面都转用静态页面机制，否则真的无法忍受这样的速度。做了.NET的b/s已经有一段时间了。cs的速度甚至让我怀疑asp.net是否合适做一个大型的b/s的系统，是否转向php, php的环境下面大型的b/s框架比比皆是，而且速度奇快，反观asp.net环境下面又大又好运行的快的真是屈指可数。我想本来asp.net 和 php在运行的效率上已经不是同一个层次了。

的确臃肿速度奇慢，但是是一个学习的很好的例子
希望能公开2007的sdk呀，继续学习

非常同意上面的观点,程序臃肿且速度奇慢,再加一个,如果使用虚拟主机,需要的配置也非常复杂

这程序臃肿且速度奇慢

对cs确实没啥兴趣...

- Cleaned up ban user experience. When you select to ban a user the ban tab appears and is focused, in addition the forceLogin option is selected.
- The create new blog form has been simplified to only include necessary fields.
- Rearranging subforums in the tree view keeps the new order that is chosen both in the control panel and in the forum views.


Help text clean-up and Improvements

- Fix: Fix for subject needing to be HtmlDecoded in notification emails
- Fix: CSLinks roles are now fully compared to the roles that a user has.

能把readme 发上来么， 看看修正了哪些BUG

改改多语言支持吧,例如把所有语言加载到HashTable,然后存入Cache.根据当前用户操作系统类型,通过ResoureManager从内存中读去相关资源.

不知道。NET有什么好。 也许是另一个COM吧。

我也很矛盾这几个月来一直在DELPHI，VS2005中徘徊，不怎么办，放弃DELPHI我感觉很可惜，我的第一个商用程序是DELPHI编写的，谈不上赚钱，但给我工作带来的空前的便利，现在听说DELPHI一天一天的接近VS。我很迷茫，我虽然不是真正的程序员，但是要放弃DELPHI，去学C#。NET，我也不知道。好多论坛上写MS是现在老大，跟着他走应该不会有错的，必竞他现在是计算机巨头。也许他的话是正确的。

很好的文章,对入门者很有帮助。
VM ware 这么好 ，在哪里下载呢？

为什么登录是空密码可以,一旦密码不为空,就难证出错?

VB.NET LDAP 如何修改用户资料？如果我想修改密码应该怎么作啊？

瓦，你什么公司啊？强啊

界面应该也有版权吧？干吗这么多软件抄袭微软的界面微软都没有去告他们呢？WPS 抄 OFFICE，开发工具就更不用说了……

这几年我一直在Delphi8、Delphi2005、delphi2006、VS2002、VS2003、VS2005之间徘徊，其实delphi2006与VS2005都可以用，并且二者还越来赿相似，要不是microsoft拥有windows平台，Borland Delphi可能早早就超赿了microsoft的编程工具。

虚拟机我用了很多年，也用过了很多的版本，不过现在我电脑里用的是Connectix Virtual PC 5.1，看好了，是Connectix而不是Microsoft,我测试过，效能比vmware快，我在我的一台老本本（IBM T20 PIII750 256M 40G）上用Connectix Virtual PC安了REDHOT 9.0 ，用起来也不慢

下面是我以前在CSDN发的一篇关于DropDownList的文章.请指正啊.
==========================


在ASP.Net里,如果你的DropDownList控件是在运行时候动态从数据库里取数据然后
Items.Add进去的,那么当你选择一个项后状态根本不能保存下来,而且也取不到你的
选择值,这个咋个整啊?为何不用JavaScript试试呢.于是就试成了,拿出来给遇到同样
问题的弟兄.希望有所帮助.举个取值的例子:

(1)先在WebForm里放一个DropDownList1,一个TextBox1.然后我们要实现的是在DropDownList1选择
后,在TextBox里把值显示出来;(注意这里DropDownList里的Items项是在PageLoad时候动态添加进去的
数据库字段)

(2) 在PageLoad里代码如下意思(代码不完整,表示个意思):

:
:
While Reader_DBFields.Read()
DropDownList1.Items.Add(Trim(Reader_DBFields.GetString(0)))
End While
:
:

(2)把WebForm切换到HTM代码模式,然后添加JavaScript如下:
<script language="JavaScript">
function onDropSel()
{
document.getElementById("TextBox1").value = document.getElementById("DropDownList1").value;
return ;
}
</Script>
:
:
(3)找到定义DropDownList那段代码,加入OnChange事件,代码为:OnChange="javascript:onDropSel()"
<asp:dropdownlist id="DropDownList1" style="Z-INDEX: 121; LEFT: 515px; POSITION: absolute; TOP: 196px" runat="server" Height="24px" Width="196px" Font-Size="Smaller" OnChange="javascript:onDWsel();"></asp:dropdownlist>


然后运行,选择DropDownList的项,看到在TextBox里显示出你的选择值就OK了.

以下目录服务配置参数:
hostname=110.167.100.211
port=676
basedn=o\=lspc,o\=silspc
binddn=cn\=Directory Manager
bindpassword=abcde123

你好,请问这个LDAP的目录访问怎么弄啊?能不能给解释一吓.

上面的代码我也用过,可惜转换总是不正确,实在是头痛,不如直接用DataTable实例.要说显示TreeView应该Row不会太多,不存在问题.

就是因为borland没有自己的像microsoft一样的windows　所以他也一直只有在后面跑，哎，想想还是够惨的，其实花了那么多年在delphi上我觉得好后悔，我想回到microsoft的软件开发上去，因为borland的bug太多，他们都认为现在的内存便宜，而没有想过如果是用本本来写东西是一个怎么样的感受，我是delphi2006一出来就有了设计师版　的，我觉得还是用d7可以写win32的程序，至于.net就算了吧，因为microsoft都 .net framework的版本还是2.0了，所以borland始终不跟不上来，不过我觉得如果delphi就这样悄然的陪着diva一起死去，我想还是很可惜的，用过delphi的朋友们我们用客观的态度来评价bds2006吧，功能是太多，就是觉得像一大象，拉不动呀，bds2006如果能像d7占用系统资源那么少的话，应该还是会受欢迎的，不知道现在的borland又在怎么走，他们还来得急自己拥用一个像microsoft的windows吗？我想是不可能的，作为一个企业不可能花那么大的心血而得不到回馈的，所以我想要在.net上borland始终都是输家。。。

我也遇到了这个问题，刚开始觉得很奇怪

请教：vmware 4.5or 5.0下，我装了win98,可是声卡驱动没有了，或者说声卡不能用，应该怎么解决？谢谢了

确实如此，我经历了类似的情况。
现阶段也是找一合伙人的方式

试过D2006，感觉还是把一大堆乱七八糟的东西拼凑在一起，速度慢，而且.net framework的版本还是1.1的，为什么跟着microsoft的后面跑呢？自己做个framework不行吗？

VMWare5.0以后的版本的确支持D3D功能,但是默认是没有打开的,必须手动打开.
先配置好一个虚拟系统,找到后,用文本方式打开,添加如下内容:
mks.enable3d = TRUE
svga.vramSize = 输入你想要的大小,注意,单位是byte,要乘两次1024
vmmouse.present = FALSE
保存,就打开D3D功能了.

强烈推荐网博士，爱不释手，我的最爱！

Delphi2006的确做得很棒，出乎意料的稳定，这给了我们这些DelphiFans一份大礼，确实太出彩了！

楼主可以试试！

也许我们可以用变通的方法来实现,比如我们用一7的倍数来表示同一VALUE的值,最后作判断,如果可以整除就认为它是同一VALUE,一点拙见~~~

kkkkk

value值重复是经常发生的事，有没有解决的方法。。。

好。VS的那些自动生成代码我可不喜欢。偶用SPL做的系统可以多数据库移植。。

是啊！哈哈。

21000，公司出钱买的。

多少钱啊？估计个人买不起！
