How to clear form controls from Top objects in the Finalizer queue

Hi ,

We have recently migrated from VB6 application to VB.NET 3.5  and contains lots of forms.

As I open form memory increases and after closing the form it remains the same. So after some time the memory goes on increasing and app becomes very slow. Memory Profiler showed many from controls like ToolStripDropDownMenu ,GroupBox andSaveFileDialog in Top Objects in the Finalizer Queue.

How to clear this queue or is there any way to force free the memory held by form objects.

Code :

Private Sub frm_Test_Closed(ByVal eventSender As Object, ByVal eventArgs As EventArgs) Handles MyBase.Closed
      Try
             GC.Collect()
              GC.WaitForPendingFinalizers()
              GC.SuppressFinalize(Me)
              Me.Dispose()
      Catch ex As Exception
         InEventViewer.LogError(ErrorConstants.THRUST_ERROR_032, ex)
      End Try
   End Sub
