本文介绍了聊天系统中数据发送的具体实现方式，详细解释了如何通过CChatDataPDU与CRTMessageBlock来完成消息的编码与发送流程。文章还探讨了不同消息类型（公共或私人）的处理区别。

CChatDataPDU与CRTMessageBlock什么关系？

// data format:
// "1,user name,user input message"  // public
// "0,user name,user input message"  // private
void CChatMainDlg::SendData(BOOL bPublic, CString& cSender, CString& cMessage)
{
if (m_chatsession.IsConnect())
  CHARFORMAT cf;
  cf.cbSize = sizeof(CHARFORMAT);
  cf.dwMask = CFM_CHARSET | CFM_FACE;
  m_input.GetDefaultCharFormat(cf);

  CChatDataPdu pdu;
  pdu.m_bPublic = bPublic;
  pdu.m_cSender = cSender;
  pdu.m_cMessage = cMessage;
  pdu.m_bChatSet = cf.bCharSet;
  pdu.m_cFaceName = cf.szFaceName;

CRtMessageBlock aData(pdu.GetLength());
pdu.Encode(aData);

int nLen = pdu.GetLength();
LPCSTR lpData = aData.GetTopLevelReadPtr();

  if (bPublic == FALSE && m_bPublic == FALSE)
  {
   InfoUser_ID user(m_idChatUser);
   m_chatsession.SendChatData(nLen, (const LPBYTE)lpData, &user);
  }
  else
  {
   m_chatsession.SendChatData(nLen, (const LPBYTE)lpData);
  }

}
}
