I get the following error with the code below it:

Direct ODBC: Couldn't connect to Driver

Code:
char szDSN[256] = "Driver={Microsoft Access Driver (*.mdb, *.accdb)};DSN='';DBQ=C:\\Users\\Sasuke\\Documents\\Database1.accdb;";

//LPCTSTR lpszConnect = _T("Driver={Microsoft Access Driver (*.mdb, *.accdb)};DSN='';DBQ=C:\\Users\\Sasuke\\Documents\\Database1.accdb;");

I'm using access 2010, so what's missing here?
