how to delete a table from MS ACCESS database from asp.net using VB.net

Hi All,

I am trying to develop a web application in asp.net where my database is in MS ACCESS.

Dim conn As OleDbConnection
Dim mycommand As OleDbCommand
Dim connString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\CBPCleanData\Result File\" & tname
conn = New OleDbConnection(connString)
conn.Open()

mycommand = New OleDbCommand("delete * from cbp_prest2", conn)
mycommand.ExecuteNonQuery()
mycommand.CommandText = "delete * from cbp_prest3"
mycommand.ExecuteNonQuery()
mycommand.CommandText = "delete * from cbp_prest4"
mycommand.ExecuteNonQuery()
mycommand.CommandText = ("delete * from cbp_prest4_sic")
mycommand.ExecuteNonQuery()

when I used the above code I am getting the following error.
:

Could not delete from specified tables.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

I am new to .net programming. Can anyone help me to overcome this problem.

Thanks
