看看这样读注册表对不对？解决办法

看看这样读注册表对不对？

C/C++ code

char path[254]="SYSTEM\\CurrentControlSet\\Control\\Network\\{4D36E972-E325-11CE-BFC1-08002BE10318}\\";//这个是预写好的//pTemppip->AdapterName是从系统API读过来的网卡编号,类似是{C31B0A6A-3265-4E19-82A7-C9C6B26EEC6C}    //pSourceip是从系统API读过来的网卡列表信息的首地址//iadapternum是网卡的个数//下面这段代码的意思是循环各个网卡的编号，然后从注册表读网卡的名字。匹配是否有网卡名叫NETA和NETB的。              pTemppip=pSourceip;        for(int i=0;i<iadapternum;i++)        {            char TempPath[500]={0};            strcat(TempPath,path);            strcat(TempPath,pTemppip->AdapterName);            strcat(TempPath,"\\Connection");            int ret=RegOpenKeyEx(HKEY_LOCAL_MACHINE,(LPCTSTR)TempPath,0,KEY_READ,&hKey);            if(ret==ERROR_SUCCESS)            {                BYTE name[MAX_PATH]={0};                DWORD bufLen=MAX_PATH;                DWORD type_1=REG_SZ;                ret=RegQueryValueEx(hKey,"Name",NULL,&type_1,(LPBYTE)name,&bufLen);                if(ret==ERROR_SUCCESS)                {                    if(strcmp((char *)name,"NETA")==0)                    {                        g_bHaveSnetA=TRUE;                        m_SnetAIndex=pTemppip->Index;                    }                    if(strcmp((char *)name,"NETB")==0)                    {                        g_bHaveSnetB=TRUE;                        m_SnetBIndex=pTemppip->Index;                    }                }                RegCloseKey( hKey );            }                            pTemppip=pTemppip->Next;            if(pTemppip==NULL)                break;        }

但是实际结果是有些机器正常，有些机器会崩溃。

[解决办法]
摘个MSDN的例子：

C/C++ code

            HKEY hKey;            char szProductType[BUFSIZE];            DWORD dwBufLen=BUFSIZE;            LONG lRet;            lRet = RegOpenKeyEx( HKEY_LOCAL_MACHINE,               "SYSTEM\\CurrentControlSet\\Control\\ProductOptions",               0, KEY_QUERY_VALUE, &hKey );            if( lRet != ERROR_SUCCESS )               return FALSE;            lRet = RegQueryValueEx( hKey, "ProductType", NULL, NULL,               (LPBYTE) szProductType, &dwBufLen);            if( (lRet != ERROR_SUCCESS) || (dwBufLen > BUFSIZE) )               return FALSE;            RegCloseKey( hKey );

看这像是指针错误，应该跟读注册表没关系吧。

好好调试一下。
[解决办法]
检查字符串操作...
[解决办法]
name==NULL???????
