Cub Lock Problem. Because It Is Being Used By Another Process

Hi Friends,

I am Kamesh presently facing a problem in deleting the cub file. If any one can help me
In my application
· I need to connect to the .Cub file
· fetch data
· close connection
· delete the cub file
After closing the connection the cub is still locked so I am unable to delete the file.
I am getting error "The process can not access the file '''C:Program FilesTNSOLA Cubpromotioncubfile88854793-0111-ffff-ffff-ffffffffffff.cub" because it is being used by another process.

Simply i tried open the cub and immediately closing the connection and called GC.Collect()
Trying to delete the cub file. It is not accepting.

Looking forward for any help.

Regards

Kamesh.

Code which i used is mentioned below.
using VS 2005 frame work 2.0.

Imports System.IO
Imports Microsoft.AnalysisServices.AdomdClient


Dim objConnection As New AdomdConnection

Try


objConnection.ConnectionString = "Provider ='msolap';Pooling='False'; Data Source = 'C:Program FilesTNSOLA Cubpromotioncubfile88854793-0111-ffff-ffff-ffffffffffff.cub'"
objConnection.Open()


'objConnection.Close()
objConnection.Dispose()
GC.Collect()

File.Delete(cubpath)
Catch ex As Exception
MsgBox(ex.Message)
End Try
