这几天考试之余,闲来无事,发现所做程序自启动的access数据库连接错误, 而启动后重新打开文件就可以正常连接数据库.
问题分析好久,经过排查,问题在于数据库的启动路径有问题,在连接数据库 时候可以这样写
GetModuleFileName(NULL,path,255);//获得自启动的程序完整路径;
CString str;
str.Format("%s",path);
int place;
place = str.ReverseFind( '\\' ); //获得最后一个'\'的位置;
CString db_name;
db_name = str.Left(place+1) + "qijian.mdb"; //整合出access数据库完整路径
CString connect; //连接的第一个参数
connect = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + db_name + ";";
hr = theApp.m_pConnection->Openconnect.GetBuffer(connect.GetLength()),"","",adModeUnknown); //参数带入并连接
其余代码不必多改 .
