网页调用ActiveX，在同一页面中切换时会死掉，cpu占50%。 在新窗口中调用没有问题。应该是共享变量的问题下面是引用网上一个人的话“如果在两个IE中运行，每一个IE就会把控件当作一个进程来执行，两个IE中的控件就是两个独立的进程，相互之间没有任何关系，但同一个IE的不同TAB时，IE则开一个进程，把打开的多个控件分别当作一个线程，那么此时问题就来了，多个线程之间会共享资源的，在我的控件中，引起问题的就是全局变量问题。” 我之前曾经删除过一个全局对象，然后给同事在网页上用这个控件，他说没问题了。我当时挺高兴。后来那又告诉我又有问题了。 我又检查了一下我的代码 。发现还有两处共享数据。分别是：
typedef struct _value{
double dValue;
CTime ValueTime;
}value;typedef struct{
void (*GetData)(CTime beginTime,CTime endTime,unsigned long param);
unsigned long param;
}GETDATA_T;
一个是全局结构体，一个是回调函数。 全局结构体 不方便 定义成局部的， 要改的太多了。 这个回调函数我也不知道能不能写成局部了，不太用回调函数。 大家帮我分析分析， IE卡死的原因会是上面的全局结构体和 回调函数引起的吗？
rendao0563高手你终于出现了，我都想死你了。
回调函数我已经成员化了。 之前有很多全局结构体， 我都成员化了。就差上面的一个了。我正努力呢。要改的地方比较多。

我今天上午已经把所有的结构体和一个 回调函数成员化了。 可是还是有同样的问题。 并且还带来了其它的问题。所以我又改回来了。 所以我说我已经没有什么办法了。 如果实在没什么办法，那就只有打开一个页面就重新弹出一个窗口了。
情况二： 远程下载同样的ActiveX. 死IE原因在哪里呢？
你的ActiveX实现safety相关了没？情况一： 用我本地的ActiveX,不下载。 不死IE
情况二： 远程下载同样的ActiveX. 死IE 上面2个你没有说明怎么死的。是指你打开多个页面。还是单个就死？
情况二： 远程下载同样的ActiveX. 死IE 情况一在什么情况下都不死。就是有一个页面。上面有几个链接 比如：曲线1。曲线2。如果现在显示的是曲线1. 我再点 曲线2 的话。 情况二就会死（弹出新窗口打开不死，在同一窗口中打开会死）。
数字签名这个。我叫他加。看能不能加上。你的ActiveX实现safety相关了没？ 这个概念我没听过。所以实现没实现我还不知道 。
mfc实现头文件部分
代码转过来的。 你弄弄看好了。 你说的那个假死我也碰到过。不过我IE设置完以后就不再出现了。
因为不同IE安全设置还不同。所以这个接口能实现还是实现一下。------------------------------------------------------------------ DECLARE_INTERFACE_MAP() BEGIN_INTERFACE_PART(ObjSafe, IObjectSafety)
