VS2003下的紧急问题，急。

[zxm954712]

在VS2003下，发现发布的BS系统，一台机器A上开着开发环境，并已运行，在InitializeComponend()中设置断点，另外一台机器B上通过网址来运行这个BS系统，但是令人奇怪的是：在B机器上运行的BS系统竟然会跑入A机器上的开发环境中，进入这个断点，非常的奇怪，这样就导致并发操作的时候，会同时进入同一个实例中，产生异常，不知有何方法可以解决?

[zxm954712]

怎么没有人回答啊 :-(

[cpp2017]

这个是正常的.调试状态是这样的.但运行时并不是这样.

[zxm954712]

但目前运行的时候也是这样的啊

[挨踢啊挨踢]

估计你的网站不是发布上去的

[cpp2017]

但目前运行的时候也是这样的啊 ======== 目前是在调试.

生成解决方案-生成网站-发布网站

[zxm954712]

大家在发布的时候是不是把Debug这个选项变成false的啊？

[ofei]

没有碰到过
其他页面呢？

不同的请求都会开启一个新的线程或从线程池中取回一个线程来处理请求的
也就是多线程的 那么就是有可能一起进入同一个方法内了
至于为什么出异常 就不清楚了
检查你的代码

[babyrockxray]

网站处于调试状态

编译的时候选release也可以，或者在解决方案上右键-》发布网站

在这个程序中我使用了数据集DS，然后两个人同时点击“保存”按钮的时候，（注意：在保存按钮中仅仅有必填字段的检查，其他什么代码都没有），这时我单步调试过，程序进入到InitializeComponent中，然后一个给出必填字段的信息，另一个给出如下的错误：

要插入的节点出自不同的文档上下文。
