ldb not removed when i close the access database

[Nandkumar]

Hi,
I made connection using oledbconnection object to access db.
I open connection with some some function from another file access.cs which
opens connection as
oledbconnection.open()
then do some insert statements with function defined in access.cs
finally i close connection with some another function defined in access.cs as
oledbconnection.close()
now this will definitely closes connection,but ldb file which get generated
after open()
does not closes the mdb file.
please suggest what to do...
