[vtkusers] vtkODBCDatabase used on an Access database file (.mdb) not working.

I am trying to access a Microsoft Access file (.mdb) using the standard
Microsoft Access ODBC Driver with vtkODBCDatabase but the query returns an
error of "Could not execute statement:".

 

Here is the code:

 

  //Initialize the latitude and longitude to zero for inspection upon return

  double latlon[2] = {0,0}; 

      

  //This is the format for using the Microsoft Access ODBC Driver as defined
here http://www.connectionstrings.com/access#p88

  //Driver={Microsoft Access Driver
(*.mdb)};Dbq=C:\mydatabase.mdb;Uid=Admin;Pwd=;

 

  vtkODBCDatabase* db = vtkODBCDatabase::New();

            

  db->SetDataSourceName("Driver={Microsoft Access Driver
(*.mdb)};Dbq=\"C:\\Data\\app.3dd\";Uid=Admin;Pwd=;"); 

 

  vtkSQLQuery* query = db->GetQueryInstance();

 

  query->SetQuery("Select CenterLon, CenterLat FROM Sites WHERE SiteID =
'KUEX'");

 

  if (query->Execute())

    {

    while(query->NextRow())

      {

      latlon[0] = query->DataValue(0).ToDouble();

      latlon[1] = query->DataValue(1).ToDouble();

      }

    }

  else

    {

      //I get an error of Could Not Execute Statement here

      const char* err = query->GetLastErrorText();

    }

 

  query->Delete();

  db->Delete();

 

  return latlon;

 

The program compiles fine.

I can retreive rows using the .NET OleDb driver from this database using the
exact same query so I know the tables are correct.

I would like to see if I can retreive data using VTK.

I am using Windows XP and VTK with C++ in Visual Studio 2005.

Thanks.
