Show members network tree in VBasic 6 data report, and MS-SQL

Please am designing a vbasic application for networking program (i mean this referrer of a thing). please have tried all i could but no answer yet. how can i use data report, data environment, and mssql database to display a diagrammatic record list on data report. this is said to be done according to the uid select, sponsor id for sub members brought by this uid(root member).

Or do you have any sample on referring application (i.e vbasic app. the show the network of members.)
