还是线程问题:(

[cckylin]

UINT TakeData(LPVOID sid)
{
int Rsid = 0;
Rsid=*((int*)sid);
if (!CData->IsEmpty()) //*****这里出错
{}
while(1)
{
::Sleep(2000);
}

return NULL;

}

void CICPDlg::AddData(int sid,int ecount,int pid,int eflag,char *mcont)
{

Msg_Element *Msg;
Msg = new Msg_Element;
Msg->session_id = sid;
Msg->element_count = ecount;
Msg->position_id = pid ;
Msg->end_flag = eflag ; 结束标志位
Msg->msg_cont= mcont;
ListSid = 0 ;
ListSid = sid ;
if (!CData->IsEmpty()) //判断列表里是否有数据,如果没有则新开一线程工作
{

if (CData->FindData(ListSid) == TRUE)
{ //如果在列表里有该数据则不做处理

}
else
{//如果没有数据则新建一线程
pThread = AfxBeginThread(TakeData,&ListSid);
}
}
else
{ //如果列表里没有数据,则新建一线程
pThread = AfxBeginThread(TakeData,&ListSid);
}
CData->AddTail(Msg);

}
怎么样才能在线程函烽里调用CData?操作链表!

[vcforever]

在启动线程的时候将CData对象的指针传递给线程函数
CData m_data;
.......
AfxBeginThread(TakeData,&m_data);

在线程函数中
CData *pData = (CData*)lparam;
pData->//操作连表

注意操作同一个连表的时候要注意线程间的同步问题！

[cckylin]

我用的互斥在操作连表里?
在线程里还用设置同步吗?
void CellList::AddTail ( Msg_Element * c )//在MsgList最后加个值
{
WaitForSingleObject ( hMutex, INFINITE );

MsgList.AddTail(c);

ReleaseMutex ( hMutex );
SetEvent ( hEvent );
}

还是不行?
定义成全局的 CData = new CellList;

pThread = AfxBeginThread(TakeData,&ListSid,&m_data);
UINT TakeData(LPVOID sid,LPVOID m_data)
{
int Rsid = 0;
Rsid=*((int*)sid);
CData *pData = (CData*)m_data;
}
'm_data' : undeclared identifier
'*' : illegal, left operand has type 'class CellList *'
error C2065: 'CData' : undeclared identifier
error C2065: 'pData' : undeclared identifier
: error C2059: syntax error : ')'

[cckylin]

CellList *CData;//列表变量
class CellList
{
public:
CellList();
~CellList();

public:
CList<Msg_Element*,Msg_Element*&> MsgList;
HANDLE hMutex;
HANDLE hEvent;

public:
BOOL IsEmpty();
Msg_Element *GetTail();
void RemoveHead ( );
void RemoveAt(POSITION data);
void AddTail ( Msg_Element * data );
int GetCount( );
//int FindData(int sessionid,int ecount,int posid,int eflag);
BOOL FindData(int data);
};
