1、 CString類，Bot定義了自己的字符串類，與其他字符串類相比，它增加了加密字符串的功能，具體分析如下：
5個成員變量：
bool m_bIsCryptStr ; //字符串是否加密
int m_iCryptKey ; //用於加密的key的值
char * m_szString ; //保存字符串的指針
c har * m_szTemp ; //字符串臨時指針
int m_iLength ; //字符串的長度
39個成員函數：
public :
CString (); //構造函數
CString ( const char * szString );
CString ( const CString & pString );
CString ( const int iValue );
virtual ~ CString (); //析構函數
void Assign ( const char * szString ); //字符串填充函數
void Assign ( const CString & pString );
void Assign ( const int iValue );
void Append ( const char * szString ); //字符串追加寒函數
void Append ( const CString & pString );
void Append ( const int iValue );
int Compare ( const char * szString ) const ; //字符串比較函數
int Compare ( const CString & pString ) const ;
int CompareNoCase ( const char * szString ) const ; //忽略大小寫的字符串比較函數
int CompareNoCase ( const CString & pString ) const ;
CString Decrypt () const ; //字符串加密函數
void Empty (); //字符串清空函數
int Find ( const char cChar ) const ; //字符查找函數
int Find ( const char cChar , int iStart ) const ;
int Find ( const CString & pString ) const ; //字符串查找函數
int Find ( const CString & pString , int iStart ) const ;
int Find ( const char * szString ) const ;
int Find ( const char * szString , int iStart ) const ;
void Format ( const char * szFormat , ...); //字符串的格式化輸入函數
char * GetBuffer ( int iBufLen ); //字符串獲得緩衝區的函數
int GetLength () const ; //獲得字符串長度的函數
CString Mid ( int iFirst , int iCount ) const ; //截取子字符串的函數
CString Mid ( int iFirst ) const ;
CString Token ( int iNum , const char * szDelim , bool bUseQuotes ); //以特定分隔符，分割提取子字符串的函數
CString Token ( int iNum , const char * szDelim );
void operator =( const CString & sStr ); //重載賦值運算符函數
void operator =( const char * szStr );
char & operator []( int iPos ); //重載[]運算符函數
const char & operator []( int iPos ) const ;
operator const char *() const //重載*()運算符
{
return m_szString ;
}
operator char *()
{
return m_szString ;
}
const char * CStr () const ; //獲取字符串變量中，字符串緩衝區指針的函數
const char * CStr ();
char * Str ();
這裏着重分析一下 Token 函數
//////////////////////////////////////////////////////////////////////////
//
//函數功能：按照分隔符將字符串分爲若干段，
//參數： int iNum 返回第一段符合要求的字符串
// const char *szDelim 分割字符
// bool bUseQuotes 是否支持轉義字符
//返回值： CString 如果找到返回相應的子字符串，否則返回NULL字符串
//
/////////////////////////////////////////////////////////////////////////
CString CString :: Token ( int iNum , const char * szDelim , bool bUseQuotes )
{
if ( m_bIsCryptStr )
{
return Decrypt (). Token ( iNum , szDelim , bUseQuotes );
}
std :: vector < char *> vTokens ; //注意這裏是一個字符指針數組類型
CString sTemp ( m_szString );
char * szText = sTemp . Str ();
bool bInQuotes = false ;
while (* szText )
{
while (* szText == szDelim [0])
{
//尋找字符串中的分割字符，找到後跳出循環
szText ++; // skip leading whitespace
}
//如果分割符爲“"”雙引號，bInQuotes賦值爲true
bInQuotes =(* szText == '/"' ); // see if this token is quoted
//如果bInQuotes爲ture
if ( bInQuotes )
{
szText ++; // skip leading quote
}
vTokens . push_back ( szText ); // store position of current token
if ( bInQuotes )
{ // find next quote followed by a space or terminator
while (* szText &&! (* szText == '/"' && ( szText [1]== ' ' || szText [1]== '/0' ) ) )
{
szText ++;
}
if (* szText )
{
* szText = '/0' ;
if ( szText [1]) { szText +=2};
}
}
else // !bInQuotes
{
// skip to next non-whitespace/delimiter character
while (* szText &&* szText != szDelim [0]) //字符串沒有結束，當前字符不是分割富
{
szText ++;
}
if (* szText &&* szText == szDelim [0]) //字符串沒有結束，當前字符是分割富
{
* szText = '/0' ; //該字符賦值爲0，及結束符
szText ++;
}
} // if(bInQuotes)
} // while(*szText)
if ( iNum >= vTokens . size ())
{
return CString ( "" );
}
return CString ( vTokens . at ( iNum ));
}
2、 CMessage 類的分析
該類沒有成員函數數，只有幾個成員變量
class CMessage
{
public :
CString sChatString ; //聊天字符串
CString sSrc ; //源
CString sDest ; //目的
CString sHost ; //主機
CString sIdentd ; //ID號
CString sReplyTo ; //回覆（答覆）
CString sCmd ; //命令
bool bSilent ; //靜默？
bool bNotice ; //通告？？
};
3、 CCmdExecutor 類的分析
class CCmdExecutor : public CThread
{
public :
CCmdExecutor () //構造函數
{
m_pMsg = NULL ;
m_bMsgSet = false ;
}
virtual ~ CCmdExecutor () { } //析構函數
virtual void * Run ();
CMessage * Get () //獲得消息類對象指針
{
return m_pMsg ;
}
void Set ( CMessage *); //設置消息類對象
private :
CMessage * m_pMsg ;
CMessage m_mMsg ; //消息類變量
bool m_bMsgSet ;
};
（1）、 : Run () 函數
/////////////////////////////////////////////////////////////
//
//函數功能：繼承線程類的run函數
//
///////////////////////////////////////////////////////////////
void * CCmdExecutor :: Run ()
{
while (! m_bMsgSet ) //如果沒有消息設置，休息1秒鐘 ，再判斷
{
Sleep (1000);
}
g_cMainCtrl . m_cBot . Recv (& m_mMsg ); //接收消息
g_cMainCtrl . m_lCanJoin . push_back ( this ); //將消息對象放到線程列表中，因爲消息類繼承了線程類
return NULL ;
}
（2）、 Set ( CMessage * pMsg ) 函數
////////////////////////////////////////////////////////////////////
//
//函數功能：設置消息
//參數： CMessage *pMsg 消息類對象指針
//返回值：void
//
//////////////////////////////////////////////////////////////////////
void CCmdExecutor :: Set ( CMessage * pMsg )
{
m_pMsg = pMsg ; //將消息類對象指針賦值給成員變量
m_mMsg . bNotice = m_pMsg -> bNotice ;
m_mMsg . bSilent = m_pMsg -> bSilent ;
m_mMsg . sSrc . Assign ( m_pMsg -> sSrc ); //賦值消息源
m_mMsg . sIdentd . Assign ( m_pMsg -> sIdentd ); //賦值ID
m_mMsg . sHost . Assign ( m_pMsg -> sHost ); //賦值主機名
m_mMsg . sDest . Assign ( m_pMsg -> sDest ); //賦值目的地
m_mMsg . sChatString . Assign ( m_pMsg -> sChatString ); //賦值聊天字符串
m_bMsgSet = true ; //將m_bMsgSet設爲true，使run函數啓動。
}
3、 CIRC :: Run () CIRC類的run函數
void * CIRC :: Run ()
{
while ( m_bRunning && g_cMainCtrl . m_bRunning )
{
//CIRC類的成員變量中的m_bRunning變量爲true,並且全局變量CMainCtrl類型的g_cMainCtrl變量的

//如果連接失敗，在這裏處理善後工作
if (( m_iServerNum ==0 && m_iFailCount >5) || ( m_iServerNum !=0 && m_iFailCount >2))
{
//如果連接的是0號服務器並且連接失敗次數大於5；或者連接的不是0號服務器，並且連接失敗次數大於2，執行if裏的代碼
// Reset CIRC values, disconnect the sockets, and clear the logins
m_bJoined = false ;
m_bConnected = false ;
if ( m_sSocket != INVALID_SOCKET )
{
xClose ( m_sSocket ); //通過宏定義調用closesocket，關閉套接字
}

#endif // DBGCONSOLE
