I've go a set of large applications that were developed in Visual Studio 2005 and were working fine until I tried to do maintenance in VS 2012. At the heart of the problem is the open code::
Code:
	// The DBQ is the path and file name (fully qualified)
	// The driver, inside the {} is magic for the exact driver name
	//   which can be obtained from the ODBC administrator
	// The UID is also available from the ODBC administrator
	csBuffer = "ODBC;DBQ=";
	csBuffer += m_csDatabasePath;
	csBuffer += ";Driver={Microsoft Access Driver (*.mdb)};UID=admin";

	m_pTestDatabase = new CDatabase;

	TRY
	{
		//m_pTestDatabase->Open(NULL, FALSE, FALSE, (const char*)csBuffer);
		BOOL bSuccess = m_pTestDatabase->OpenEx((const char*)csBuffer);
		TRACE("OpenEx(%s) returned %s\n", csBuffer, bSuccess ? "true" : "false");
	}
	CATCH(CDBException, except)
	{
		csBuffer += "\nODBC ";
		csBuffer += except->m_strError;
		EndWaitCursor();
		AfxMessageBox(csBuffer, MB_OK | MB_ICONSTOP);
		delete m_pTestDatabase;
		m_pTestDatabase = NULL;
		return true;
	}
	END_CATCH;
and::
		// default options permit read, write, and append
		m_pTblPlot->Open(CRecordset::snapshot, NULL, CRecordset::none);
		if( !m_pTblPlot->CanUpdate() )
		{
			AfxMessageBox("SS Plot Specification database cannot be updated.", MB_OK | MB_ICONSTOP);
		}
If I proceed I find that I can read the record set but can not update it. I've got Access 2007 installed on my computer. Any suggestions?
