I am developing a windows application in VB,  In which i store all the contact information, it is like an address book. I have to take the information about the relation ship between the person(whose information is being stored) and himself... Like whether he is a superior  or a subordinate or just an employee... Now based on this information, i need to build a 2D tree view which shows his superiors above him and subordinates below him. Now, how can i build this tree??? It has to take the information from the database and display the tree..
Please advise...

I have done that for family relationships with a Treeview control. However, the hierarchy goes across the page instead of down the page, so that might not suit you.

Possibly, but it is rather specialised. In principle it is recursive search. This is some pseudocode.

Usage is: Call TopBossID, 1

Sub GetReportees(MemberID, Level)
    sgl = select * from mytable where BossID= MemberID
    rs.open sql
    do until rs.eof
           AddToTree Member, Level
           GetReportees MemberID, Level+1
end sub
