Excel issue in Local web server

[danasegarane]

Hi all,
I am using this code to get th ProcessID of newly Created Excel.

Imports Microsoft.VisualBasic
Imports Microsoft.Office.Interop
Public Class Class1
    <Runtime.InteropServices.DllImport("user32.dll", SetLastError:=True)> _
  Private Shared Function GetWindowThreadProcessId(ByVal hwnd As Integer, _
                            ByRef lpdwProcessId As Integer) As Integer
    End Function

    Private processId As Integer
    Sub New()
        Dim oExcel As Excel.Application
        oExcel = CreateObject("Excel.Application")
        GetWindowThreadProcessId(oExcel.Hwnd, processId)
        oExcel.Quit()
        System.Runtime.InteropServices.Marshal.ReleaseComObject(oExcel)
        oExcel = Nothing
    End Sub
End Class

This code returns the Process ID Correctly with Virtual Server
Now I deployed it using a Website, and the ProcessID is 0

Has anyone experienced with this ?
