多线程传参问题(急啊！)

typedef struct ThreadPara

CString commandCode;
CString blockId;
int length;
unsigned char* dataBuff;

void CClientSocket::OnReceive(int nErrorCode)

}

}

}

CString strstr = HexToStr(0,66,threadParam->dataBuff);
AfxMessageBox("strstr"+strstr); //有时候前32字节及倒数2字节正确,
//有时候就前5个字节正确,后面就不只是

//什么了,奇怪的是后面的错误数据有时候几次出现都是一样的，好像不是随机的，怎么回事？哪里

//出了问题？

AfxMessageBox(threadParam->blockId); //这里数据也正确
AfxMessageBox(threadParam->commandCode); //这里数据也正确

CString idTemp = HexToStr(2,6,threadParam->dataBuff);
AfxMessageBox("idid="+idTemp); //这就不对了，即使前32字节正确时，也不对


................................

delete threadParam;
return 0; //线程关了没? 需要void AfxEndThread(0); ???
}
CString CClientSocket::HexToStr(int i,int n, unsigned char* strPara) //类静态成员函数
{
char pTemp[2050];
char pDest[2050];

sprintf(pTemp,"%02X",strPara[j]);
strcat(pDest,pTemp);
}
return pDest;
}
高手帮忙看看，急啊！！！

那先看看这个

[blury]

谢谢 BUbuWander(Dead or alive,I'm coming with you.)

我看过你给的资料了。

可我只做了一个简单的工作线程，不用消息循环的。

[BUbuWander]

先 mark 再看，return 0;关了

你把return 0前代码用while（true）框起来再测试下，选一个情况break

[blury]

问题没变啊，每次第33字节为90,而倒数两字节却正确。

[BUbuWander]

sendmessage 之前没问题？

[blury]

那块需要发消息阿？我不知道，我好像没用到。唉..什么也不懂，搞这玩艺儿，头疼死了。

放弃，重来。类似的问题出现：
SYTPICSvr.cpp ：
unsigned char* tempDataBuff;


void CSYTPICSvrApp::AddMissionToThread(unsigned char *charData, CString commandCode,long length)
{
if (length<= 0)
return;

if ( length <= 1012)
{
length += 12;
}
else
{
length = 32;
}
if (length != 0)
{
tempDataBuff = charData;
CString testtest = HexToStr(0,length,tempDataBuff);
AfxMessageBox("lalala"+testtest); //显示数据完全正确
pMyThreadPoolManager->AddMission(&m_ThreadE);
//接下来运行ThreadE.cpp中的ExecThread()
}
}

ThreadE.cpp ：

extern unsigned char* tempDataBuff;
void CThreadE::ExecThread()
{
long length = 0;
CString testData = ((CSYTPICSvrApp*)AfxGetApp())->HexToStr (0,1024,tempDataBuff);
AfxMessageBox("1212121212=="+testData );
//有时正确，有时不正确
CString blockId = "";
blockId.Format("%d",(int)tempDataBuff[7]);
AfxMessageBox("blockId=="+blockId);
//显示不正确，不管上面的正确与否，他都不正确。
CString strLength = ((CSYTPICSvrApp*)AfxGetApp())->HexToStr(8,10,tempDataBuff);
sscanf(strLength, "%x", &length);
AfxMessageBox("strLength=="+strLength);
//显示不正确，不管上面的正确与否，他都不正确。
}
tempDataBuff 到底是怎么回事啦？看懂得帮我看看哪里有问题？谢谢！

[blury]

是参数生命期的问题吗？

[BUbuWander]

tempDataBuff 先用 sscanf转换为 int 再使用 CString::Format()

[blury]

结了，感谢 BUbuWander(Dead or alive,I'm coming with you.) 多次光顾！呵呵
