接收ip信息的问题，请高手出招！！！

Question

先在CConferenceView类中接收数据，并向CMainFrame类发送消息事件
msg.Serialize (*m_pArchiveIn);
AfxGetMainWnd()->SendMessage(WM_ADDLIST+2, (LPARAM)&(msg.ip), 6);
CMainFrame类中响应事件相关代码如下：
[code=C/C++]void CMainFrame::OnAddIp(WPARAM wParam, LPARAM lParam)
{
CString* pStr = (CString*)wParam;
char sCall[20];
Call(sCall,PORT,1);
pStr->ReleaseBuffer();
}
上面这样调用Call方法怎么显示不了视频数据呢？我直接这样写Call("127.0.0.1",PORT,1)是可以显示视频图像的。请高手指点,谢谢！！

Call方法是这样定义的：
BOOL CMainFrame::Call(char *ip, unsigned short port,int flag)
{
BOOL bRet=FALSE;
CString strIP,ssIP;
ssIP=(LPCSTR)ip;
POSITION pos;
if (m_ClientInfoList.GetCount()!=0)
{
for( pos = m_ClientInfoList.GetHeadPosition(); pos != NULL; )
{
CClientInfo *pClientInfo=m_ClientInfoList.GetAt(pos);
strIP.Format("%d.%d.%d.%d",
pClientInfo->m_Cmddst.sin_addr.S_un.S_un_b.s_b1,
pClientInfo->m_Cmddst.sin_addr.S_un.S_un_b.s_b2,
pClientInfo->m_Cmddst.sin_addr.S_un.S_un_b.s_b3,
pClientInfo->m_Cmddst.sin_addr.S_un.S_un_b.s_b4);
if (strIP==ssIP)
{
AfxMessageBox(strIP+" have been joined in!");
if (pClientInfo!=NULL)
{
pClientInfo=NULL;
delete pClientInfo;
}
return FALSE;

}
m_ClientInfoList.GetNext(pos);
}// end of for                                                
} SetCmdDst(ip,port);
SetAVDst(ip,port+1);
PACK_CMD pc;
pc.flag=FLAG_CMD;
for (int i=0;i<MAX_CONNECT_USER;i++)
{
if (ssIP==sIP[i])
{
pc.m_ChatNo=m_ChatNo[i];
}
}
pc.cmd=CMD_JOIN;
pc.type=0;
pc.data_size_extra=0;
pc.ext=VER_TVMEETING&0xff;
char sz[50];
m_sockaddr=GetCurrentAddr();
sprintf(sz,"%d.%d.%d.%d",
m_sockaddr.sin_addr.S_un.S_un_b.s_b1,
m_sockaddr.sin_addr.S_un.S_un_b.s_b2,
m_sockaddr.sin_addr.S_un.S_un_b.s_b3,
m_sockaddr.sin_addr.S_un.S_un_b.s_b4);
if(!SendCmd(&pc,sizeof(pc),m_Cmddst,TRUE))
{
return FALSE;
}
bRet=TRUE;
return bRet;
}

这样显示看看行不行？
void CMainFrame::OnAddIp(WPARAM wParam, LPARAM lParam)
{
CString* pStr = (CString*)wParam;
char sCall[20];
strcpy(sCall,pStr.GetBuffer(pStr.GetLength()));
Call(sCall,PORT,1);
pStr->ReleaseBuffer();}
