Import from Included Sample Access Database

We have included a small Access database in the Samples folder called stars.mdb and the following OC code shows how to control the database to import into active worksheet:

#include <..\Originlab\datasource.h>
void Import_Database_Ex()
	Worksheet	wks = Project.ActiveLayer();
	if( !wks )
	// set settings to worksheet
	string	strDatabaseFile = GetAppPath(1) + "Samples\\Import and Export\

	if( strDatabaseFile.IsFile() )
		string	strConn;
		strConn.Format("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=%s; 
User ID=admin; Password=;", strDatabaseFile);			
		string	strSQL = "Select Stars.Index, Stars.Name, Stars.LightYears, 
Stars.Magnitude From Stars";
		if( db_wks_set_query(wks, strConn, strSQL) )
			//do import 
			db_wks_import(wks, 0, 0, true);
			// remove settings from worksheet
		MessageBox(NULL, "Fail to set query to worksheet.");
		string	strErr;
		strErr.Format("Not found database file %s under %s", 
GetFileName(strDatabaseFile), GetFilePath(strDatabaseFile) );
		MessageBox(NULL, strErr);
