COM中讨厌的 RtlSizeHeap, ActiveX host in IE

内存管理的问题

I didn't have time to get to the bottom of this --- though I suspect that it's related to COM BSTRs (or VARIANTS) and the handling/deallocation of them. There are some strict rules as to who has to free BSTR memory -- check out MSDN to get some more info on this. I've also found that heap management under Windows 2000 is quite a bit different than NT 4. There seems to be more heap optimization going on -- which causes some code (probably written incorrectly!) to blow that worked fine in NT4.

In the case of my original post, I didn't have time to go back and trace everything out, so I brought the VC++ ADO COM object into my source as a CLASS module instead of a COM object (which in this one case cleared things up). As noted above, I'm sure the issues were mine -- and related to how BSTRs or variants were being handled. Sure seems strange that ALL the addresses for all three problems were the same! Anybody have any other ideas?

下面是一个低级错误:
>>I get the above error when i return a string parameter
>>of LPCSTR type

Is it a string literal? IOW, are you doint sth. like

LPCSTR foo()
{
LPCSTR _p = "123";

return _p;
}

If so, change it to use a non-const memory area, e.g.

LPCSTR foo()
{
LPCSTR _a [] = "123";

return _a;
}

我想，道理是一样的不过，出现问题的情况会比上面复杂的多！

异质编译连接的问题

又一个,同一内存释放了两次

而我碰到的问题不在上面的范畴之内,一个ActiveX的事件，用attachEvent多次处理后，会随机产生RtlSizeHeap错误，改用[script for="ID" event="Event" language="javascript"][/script],错误消失，在attachEvent的时候对传给事件处理程序的参数被修改了，所以产生。但为什么前者会产生这种现象呢，还不清楚！

后来在google里面找ActiveX attachEvent的相关资料，大多是关于标准HTML元素的，对ActiveX较少，不过找到一本不错的书！ 构建WEB应用程序的人非常值得去读一下！http://book.itzero.com/read/others/McGraw.Hill.Osborne.JavaScript.2.0.The.Complete.Reference.Second.Edition.eBook-LiB_html/8166final/toc.html
