Lookup with range

Lookup with range:

     QueryBuildDataSource    queryBuildDataSource;

    SysTableLookup          lookup;

    QueryBuildRange         queryBuildRange;

    Query                   query;

    query = new Query();

    // Add the first data source to the query

    queryBuildDataSource = query.addDataSource(tableNum(DNGRSBuildingBlocks));

    // Add the range to this first data source

    queryBuildRange = queryBuildDataSource.addRange(fieldNum(DNGRSBuildingBlocks, BuildingId));

    // Set the range

    queryBuildRange.value(netfloor.BuildingId);

    lookup = SysTableLookup::newParameters(tableNum(DNGRSBuildingBlocks), this, true);

    lookup.parmQuery(query);

    // Add the fields to be shown in the lookup form.

    lookup.addLookupfield(fieldNum(DNGRSBuildingBlocks, BlockID));

    //lookup.addLookupfield(fieldNum(JournalizingDefinition, JournalizingDefinitionDesc));

    //lookup.addLookupfield(fieldNum(JournalizingDefinition, JournalizingDefinitionModuleValue));

    // Perform the lookup.

    lookup.performFormLookup();
