MFC读取和写ini文件

本文内容为从当前运行目录下的SysCfg.ini文件中读写配置，工程目录：http://download.csdn.net/detail/dafenqie/9699140

1、首先定义全景变量，用来保存配置

CString g_strVideoPath;
CString g_strPtzVideoPath;
CString g_strFixedVideoPath;


CString g_strPhotoPath;
CString g_strPtzPhotoPath;
CString g_strFixedPhotoPath;


//定焦视频IP
 CString g_strFixedVideoIP;
 CString g_strIntvSysIP;
 //变焦视频IP
 CString g_strPtzVideoIP;
 CString g_strPtzUser;
 CString g_strPtzPassWord;


 DWORD g_dwFixedVideoPort;
 WORD g_wPtzPort;


 unsigned long g_fixedVideoSpace;
unsigned long g_ptzVideoSpace;

2、写读配置的函数，在对话框界面上增加一个文本框，关联变量m_strEdit用来显示读取出来的配置，增加一个按钮，在按钮中调用以下函数，显示配置到文本框中。

void CtestCfgIniDlg::GetSysCfg()
{
//向D盘写入程序数据库连接ini文件信息，默认设置如下  
//查找是否存在ini文件，若不存在，则生成一个新的默认设置的ini文件，这样就保证了我们更改后的设置每次都可用  
CFileFind finder;
BOOL ifFind = finder.FindFile(".\\SysCfg.ini");  
if( !ifFind )  
{  
::WritePrivateProfileString("CameraCfg","ip","127.0.0.1",".\\SysCfg.ini");  
::WritePrivateProfileString("CameraCfg","port","9070",".\\SysCfg.ini");  

::WritePrivateProfileString("PtzCameraCfg","ip","192.168.1.238",".\\SysCfg.ini"); 
::WritePrivateProfileString("PtzCameraCfg","port","8000",".\\SysCfg.ini"); 
::WritePrivateProfileString("PtzCameraCfg","user","admin",".\\SysCfg.ini"); 
::WritePrivateProfileString("PtzCameraCfg","password","123456abc",".\\SysCfg.ini"); 


::WritePrivateProfileString("RecordCfg","fixedVideoSpace","200",".\\SysCfg.ini");
::WritePrivateProfileString("RecordCfg","ptzVideoSpace","100",".\\SysCfg.ini");


::WritePrivateProfileString("RecordCfg","videoPath", "E:\\video",".\\SysCfg.ini"); 
::WritePrivateProfileString("RecordCfg","photoPath", "E:\\photo",".\\SysCfg.ini");
}  


    ::GetPrivateProfileString("CameraCfg","ip","127.0.0.1",g_strFixedVideoIP.GetBuffer(MAX_LENGTH),MAX_LENGTH,".\\SysCfg.ini"); 
    g_strFixedVideoIP.ReleaseBuffer();
m_strEdit += g_strFixedVideoIP+"\r\n";


g_dwFixedVideoPort = ::GetPrivateProfileInt("CameraCfg","port",9070,".\\SysCfg.ini");  
CString strTmp;
strTmp.Format("%d", g_dwFixedVideoPort);
m_strEdit += strTmp+"\r\n";

::GetPrivateProfileString("PtzCameraCfg","ip","192.168.1.238", g_strPtzVideoIP.GetBuffer(MAX_LENGTH), MAX_LENGTH,".\\SysCfg.ini"); 
g_strPtzVideoIP.ReleaseBuffer();
m_strEdit += g_strPtzVideoIP+"\r\n";


g_wPtzPort = ::GetPrivateProfileInt("PtzCameraCfg","port",8000,".\\SysCfg.ini");  
strTmp.Format("%d", g_wPtzPort);
m_strEdit += strTmp+"\r\n";


::GetPrivateProfileString("PtzCameraCfg","user","admin", g_strPtzUser.GetBuffer(MAX_LENGTH), MAX_LENGTH,".\\SysCfg.ini");
g_strPtzUser.ReleaseBuffer();
m_strEdit += g_strPtzUser+"\r\n";;
::GetPrivateProfileString("PtzCameraCfg","password","123456abc",g_strPtzPassWord.GetBuffer(MAX_LENGTH), MAX_LENGTH,".\\SysCfg.ini"); 
g_strPtzPassWord.ReleaseBuffer();
m_strEdit += g_strPtzPassWord+"\r\n";




//存储设置，包括视频存储支持的空间(G),抓拍图片的个数，视频存储每个文件的时间(分钟)，视频和图片的存储路径
g_fixedVideoSpace = ::GetPrivateProfileInt("RecordCfg", "fixedVideoSpace", 200, ".\\SysCfg.ini");
strTmp.Format("%d", g_fixedVideoSpace);
m_strEdit += strTmp+"\r\n";
g_ptzVideoSpace = ::GetPrivateProfileInt("RecordCfg", "fixedVideoSpace", 100, ".\\SysCfg.ini");
strTmp.Format("%d", g_ptzVideoSpace);
m_strEdit += strTmp+"\r\n";


::GetPrivateProfileString("RecordCfg","videoPath","E:\\video",g_strVideoPath.GetBuffer(MAX_LENGTH), MAX_LENGTH,".\\SysCfg.ini"); 
g_strVideoPath.ReleaseBuffer();
m_strEdit += g_strVideoPath+"\r\n";


::GetPrivateProfileString("RecordCfg","photoPath","E:\\photo",g_strPhotoPath.GetBuffer(MAX_LENGTH), MAX_LENGTH,".\\SysCfg.ini"); 
g_strPhotoPath.ReleaseBuffer();
m_strEdit += g_strPhotoPath+"\r\n";
UpdateData(false);
