MFC 中ini 文件的操作

ini 文件的 GetPrivateProfileInt 可以读取负数

CString GetAppPath()

{

CString path;

GetModuleFileName(NULL,path.GetBuffer(MAX_PATH),MAX_PATH);

path.ReleaseBuffer();

path=path.Left(path.ReverseFind('\\')+1);  //这里得到的是当前路径

return(path);

}

void CTestIniDlg::OnOK() 

{

// TODO: Add extra validation here

//CDialog::OnOK();

CString strConFilePath;

strConFilePath.Format("%s\\SpeedConf.ini",GetAppPath());

int nSpeed;

nSpeed = GetPrivateProfileInt("Configure","D1Speed",0,strConFilePath);

if(nSpeed == 0)

{

// TTRACE_EX(XH_LOG_TYPE_NORMAL, _T("SpeedConf.ini is not exited  \r\n"));

CString strTemp;

strTemp.Format("%d",-2);

WritePrivateProfileString("Configure","D1Speed",strTemp,strConFilePath); 

nSpeed = -4;

}

}
