大家好，下面的代码，请高手解释一下：

void CBbbApp::IniAdo()

{

try

{

CString temp;

char filepath[MAX_PATH];

GetModuleFileName(NULL,filepath,MAX_PATH);

temp = theApp.ExtractFilePath(filepath);//获取可执行文件的路径

//m_pCon.CreateInstance("ADODB.Connection");

CString strAdoConn;

char temp1[100];

GetPrivateProfileString("DatabaseConfig","Server","",temp1,100,temp+"login.ini");

strserver = (TCHAR *)temp1;

GetPrivateProfileString("DatabaseConfig","Database","",temp1,100,temp+"login.ini");

strdbName = temp1;

GetPrivateProfileString("DatabaseConfig","User","",temp1,100,temp+"login.ini");

strUser = temp1;

GetPrivateProfileString("DatabaseConfig","PWD","",temp1,100,temp+"login.ini");

strPassword = temp1;

strAdoConn.Format("driver={SQL Server};SERVER=%s;UID=%s;PWD=%s;DATABASE=%s", 

                                  strserver, strUser, strPassword, strdbName);

m_pCon.CreateInstance(_uuidof(Connection));

m_pCon->ConnectionString = (_bstr_t)strAdoConn;

m_pCon->Open("","","",NULL);

m_pCom.CreateInstance("ADODB.Command");

m_pRs.CreateInstance(_uuidof(Recordset));

m_pRs1.CreateInstance(_uuidof(Recordset));

// ADOFLAG = TRUE;

}

catch(_com_error)

{

//ADOFLAG = FALSE;

Flag = FALSE;

MessageBox(0,"请检查系统配置信息", "数据库连接失败",MB_OK);

return;

}

catch(...)

{

AfxMessageBox("SYS Error");

return ;

}

}
