Answer 1

if(bFineImgInf)
{
    pCurImage = new ImageStatus;
    //ASSERT(pCurImage!=NULL);
    pCurImage->lbusino = xml.GetChildAttrib("Busino");
    pCurBatch->imagestatus = pCurImage;
    delete pCurImage;
pCurBatch->imagestatus = NULL;
pCurImage=NULL;
}

Answer 2

if(bFineImgInf)
{
    pCurImage = new ImageStatus;
    //ASSERT(pCurImage!=NULL);
    pCurImage->lbusino = xml.GetChildAttrib("Busino");
    pCurBatch->imagestatus = pCurImage;
    delete pCurImage;
pCurBatch->imagestatus = NULL;  //这样好像不行哦
pCurImage=NULL;
}
朋友帮帮忙！！

Answer 3

你看看就知道了嘛
按F5，在调试状态下运行，程序退出后在“输出窗口”可以看到有无内存泄露出现，例如：
Detected memory leaks! 
Dumping objects -> 
C:PROGRAM FILESVISUAL STUDIOMyProjectsleaktestleaktest.cpp(20) : {18} normal block at 0x00780E80, 64 bytes long. 
Data: < > CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD CD 
Object dump complete. 

Answer 4

我While循环里面的改成如下
while (bFineImgInf && nTotal>1)
{
    pNextImage = new ImageStatus;
    ASSERT(pNextImage!=NULL);
    pNextImage->lbusino = atoi(xml.GetChildAttrib("Busino"));
    pCurImage->next = pNextImage;
    pCurImage = pCurImage->next;
    pCurImage = NULL;
    delete pNextImage;
    pNextImage = NULL;
}

Answer 5

if(bFineImgInf)
{
    pCurImage = new ImageStatus;
    ASSERT(pCurImage!=NULL);
    pCurImage->next=NULL;            <-----
    pCurImage->lbusino = xml.GetChildAttrib("Busino");
    pCurBatch->imagestatus = pCurImage;
    //delete pCurImage;                 <--------------这里delete了后面怎么用pCurBatch->imagestatus?,要去掉
}while (bFineImgInf && nTotal>1)
{
    pNextImage = new ImageStatus;
    ASSERT(pNextImage!=NULL);
    pNextImage->next=NULL;
    pNextImage->lbusino = atoi(xml.GetChildAttrib("Busino"));
    pCurImage->next = pNextImage;
    pCurImage = pCurImage->next;
    //pCurImage->next = NULL;   <------去掉
    nTotal--;
    //delete pNextImage;          <------去掉
}//delete的时候要先把image_struct里面的删掉
pCurImage=pCurBatch->imagestatus;
While(pCurImage!=NULL)
{
.........
pNextImage=pcurimage->next;
delete pCurImage;
pcurimage=pNextimage;
.........
}
//.....
delete pCurBatch;

Answer 6

一看这代码就知道这是一个C程序员用C++代码写的C程序

Answer 7

while (bFineImgInf && nTotal>1)
{
    pNextImage = new ImageStatus;
    ASSERT(pNextImage!=NULL);
    pNextImage->lbusino = atoi(xml.GetChildAttrib("Busino"));
    pCurImage->next = pNextImage;
    pCurImage = pCurImage->next;
    pCurImage->next = NULL;
    nTotal--;
    //delete pNextImage;
}既然是创建链表，那么就不应该new了就delelte释放，而是由一个专门的release函数等，当需要确实需要释放链表的时候，遍历链表，然后delete每一个元素..

Answer 8

pCurBatch->imagestatus = pCurImage;  我加了这句话就不行
