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 )
                return;
        
        // set settings to worksheet
        string  strDatabaseFile = GetAppPath(1) + "Samples\\Import and Export\
\\stars.mdb";       

        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
                        db_wks_set_query(wks);
                        
                        return;
                }
                MessageBox(NULL, "Fail to set query to worksheet.");
        }
        else
        {
                string  strErr;
                strErr.Format("Not found database file %s under %s", 
GetFileName(strDatabaseFile), GetFilePath(strDatabaseFile) );
                MessageBox(NULL, strErr);
        }
}
