I am using the following code already ,is the solution along these lines?

  Public Function IsTableInExistance(ByVal TableName As String) As Boolean
        Try
            conn.Open()
            Dim schemaTable As DataTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, _
                                New Object() {Nothing, Nothing, Nothing, "TABLE"})
            TableName = TableName.ToUpper
            For Each row As DataRow In schemaTable.Rows
                Dim TblName As String = row(2)
                If TblName.ToUpper = TableName Then
                    Return True
                End If
            Next

        Catch Ex As Exception
            Throw New System.Exception("An exception has occurred. " & Ex.Message)
        Finally
            conn.Close()
        End Try
    End Function

You don't need to do all that. Just issue a "Drop Table" SQL statment against the table you want removed. You can find the syntax for the drop statement in access help. Try it out first in the Query builder first. If you have records in there remember to delete them out first (if you are using relations between tables, otherwise you will get an error message about breaking the referential integrity) Use a "Delete * " SQL statment. If you have no parameters to pass place both statements as queries in access. You can then execute both of them with a OLEDB Command object. If you don't know what table it is your going to delete then use a prameter in both statements. This way you won't have to cycle throught the list of tables in your database. If the table doesn't exist you can also capture the error like you have above.
