摘要： qq聊天信息的获取和设置与自动发送 
关键字： qq聊天 文本框  消息 

一、绪言
   经常有朋友问我怎样通过程序获取qq聊天信息，笔者完成CQQChatWnd类，首先贴出类的内容，然后讲述用法。
   
二、CQQChatWnd类对外接口说明 
bool Attatch(HWND  hChatWnd); //初始化类，把hChatWnd聊天窗口同类连接
bool Detach( HWND hChatWnd);//解除类与hChatWnd的绑定
bool GetChatText(char **lplpstrText/*out*/) ;//获取聊天内容，内容存放在*lplpstrText
bool SetChatText( char * lpstrText );//设置聊天内容
bool AddChatText(char *lpstrText);//增加聊天内容
bool Chat( void );//聊天动作，模拟点击发送按钮
int  GetSysMode( void );//获取聊天模式
bool ChangeSysMode( int nSysMode );//改变聊天模式


三、用法

#include "QQChatWnd.h"

HWND  hwnd = (HWND )0x000B048A ; //qq聊天窗口句柄,根据spy++查找

CQQChatWnd  qqchatwin ;

if( !qqchatwin.Attatch(hwnd) ) 
	return FALSE ;

char * lpstrText = NULL ; //必须的

if( !qqchatwin.GetChatText( &lpstrText )) 
	return FALSE ;

delete [] lpstrText ; //数据，否则内存泄露

int nSysMode = qqchatwin.GetSysMode() ;

qqchatwin.ChangeSysMode( P2P_CHAT_MODE ) ;

qqchatwin.SetChatText( "hello, dear ") ;

qqchatwin.AddChatText( "hello, dear ") ;

qqchatwin.Chat() ;

qqchatwin.Detach( hwnd ) ;
	



四、头文件QQChatWnd.h

// QQChatWnd.h: interface for the CQQChatWnd class.
#if !defined(QQCHATWND_H)
#define QQCHATWND_H

#include <windows.h>

#define MSG_CHAT_MODE 1
#define P2P_CHAT_MODE 2


class CQQChatWnd  
{
public:
bool Chat( void );
bool AddChatText(char *lpstrText);
bool SetChatText( char * lpstrText );
bool GetChatText(char **lplpstrText/*out*/) ;
bool ChangeSysMode( int nSysMode );
int  GetSysMode( void );
bool Detach( HWND hChatWnd);
bool Attatch(HWND  hChatWnd);

public:
CQQChatWnd();
virtual ~CQQChatWnd();

private:
static BOOL  CALLBACK SearchSysModeEnumProc(HWND hwnd,  LPARAM lParam);
static BOOL  CALLBACK SearchSendButtonEnumProc(HWND hwnd,  LPARAM lParam);
static BOOL  CALLBACK SearchRichEditEnumProc( HWND hwnd , LPARAM lParam );
bool GetChatRichEditWnd( HWND *pChatRichEditWnd /*in,out*/);
bool GetChatToolbarWnd( HWND *pChatToolbarWnd /*in,out*/);
bool GetSendButtonWnd( HWND *pSendButtonWnd /*in,out*/);
bool GetModeWnd( HWND *pModeWnd /*in,out*/);
int m_nSysMode;
HWND m_hChatWnd;
HWND m_hSendButtonWnd;
HWND m_hModeWnd;
HWND m_hChatRichEditWnd;
};
#endif

五、实现文件QQChatWnd.cpp
