使用MSXML读取NodeMap时自动更改值 [英] Auto change value when read NodeMap with MSXML

问题描述

嗨所有

我有一个bug，显示为

hi all
i have a bug, show as after

MSXML::IXMLDOMNamedNodeMapPtr spNameNodeMap = spNode->attributes;
 for (long j = 0; j < spNameNodeMap->length; j++)
   {
      MSXML::IXMLDOMNodePtr spNode2 = spNameNodeMap->item[j];
      if (spNode2->nodeName == (_bstr_t)"index"){
              index = (_bstr_t)spNode2->nodeValue;
      }
      else if (spNode2->nodeName == (_bstr_t)"weight"){
              weight = (_bstr_t)spNode2->nodeValue;
      }
   }

所以，经过编译...索引和重量的值是相同的

当我调试这个错误！

i显示变量索引是地址内存！并且，当我们更改权重值时，该地址内存的值将自动更改（使用j ++循环）

和退出循环时，索引和权重的值为false，并且xml文件的数据为

如何修复它

so, after compiled...value of index and weight is equally
when i debug this error !
i show variable index is address memory! And, value of that address memory will auto change when we change value of weight (loop with j++)
and when exit loop, value of index and weight is false with data of xml file
how do what to fix it

推荐答案

我找到了问题原因

i必须更改index的类型变量从 LPCTSTR 到 _bstr_t 的重量

数据没有变化

之后，我有来自xml的数据文件，我将类型 _bstr_t 转换为 BSTR 并插入链接的列表以保存它

非常感谢阅读我的主题

i had find cause of problem
i have to change type variable of "index" and "weight" from LPCTSTR to _bstr_t
data is not change
after that, i have data from xml file, i convert type _bstr_t to BSTR and insert into a list linked to save it
thanks so much for read my topic
