char *DataBuffer= new char[1024];
char *procid= new char[1024];
char *indata= new char[1024];

}


procid = "1001";
indata = "1211|dfds|3423|322234|33234|423432|";
//执行到这里都没问题，但执行EditUserInfo时就出现崩溃错误
//文档原型是int (char *procid,char *indata,char *outdata,int *AppCode,char *DataBuffer)
if (!EditUserInfo(procid,indata,outdata,AppCode,DataBuffer)) 
{
cout<<"执行EditUserInfo成功!"<<endl;
}
else
{
cout<<"执行失败！提示信息：<<DataBuffer<<endl;
}
FreeLibrary(hInst);
}

[解决办法]
if (!EditUserInfo(procid,indata,outdata,&AppCode,DataBuffer))
[解决办法]
typedef int (WINAPI*EditUserInfo1)(char *,char *,char *&,int &,char *&);
if (!EditUserInfo(procid,indata,outdata,AppCode,DataBuffer))

你觉得对应起来了么？ *&有问题啊
&outdata &DataBuffer
[解决办法]

引用:

char *procid= new char[1024];
char *indata= new char[1024];
下面你又这样写
procid = "1001";
indata = "1211
[解决办法]
dfds
[解决办法]
3423
[解决办法]
322234
[解决办法]
33234
[解决办法]
423432
[解决办法]
";

将指向常量区的指针传递给你的接口函数，正确吗？
[解决办法]
procid = "1001";
indata = "1211
------解决方案--------------------

dfds
[解决办法]
3423
[解决办法]
322234
[解决办法]
33234
[解决办法]
423432
[解决办法]
";
改成这样
strcpy(procid,"1001");
strcpy(indata,"1211
[解决办法]
dfds
[解决办法]
3423
[解决办法]
322234
[解决办法]
33234
[解决办法]
423432
[解决办法]
";);

看来应该是返回函数的内存空间分配的问题？
就算是函数内部分配空间也不会出现崩溃，最多是内存泄露。
[解决办法]
typedef int (WINAPI*EditUserInfo1)(char *,char *,char *&,int &,char *&);
