TCHAR *pBuff=new TCHAR[40];
int iBuffSize=41;
int Rcvd;
//CString lvstrRecev;
Rcvd = m_client.Receive(pBuff,iBuffSize);
if(Rcvd==SOCKET_ERROR)
{
}

@Gokulnath007: Please stop demanding that others do your work for you. Ask clear, specific questions and you will get the help you need, but you will still have to take the initiative to make an effort.

I have solved the problem... the code is below:: thank you.. for your cooperation...

void CServerClass::OnReceive()
{
	WCHAR *pBuff=new WCHAR[100];
	int iBuffSize=99;
	int Rcvd;
	CAsyncSocket rr;

	
	Rcvd = m_client.Receive(pBuff,100);
	if(Rcvd==SOCKET_ERROR)
	{ 
	}
	else											
	{
		pBuff[Rcvd]=NULL;
		CString lvstrRecev(pBuff);
		int nLength;
		nLength = lvstrRecev.GetLength();
		CString strTemp;
		for(int i=0;i<nLength/2;i++)
		{
			strTemp += lvstrRecev.GetAt(i);
		}
		m_lrecv.AddString(strTemp);
		UpdateData(FALSE);

	}
}
