Web Service Enabling a VB.Net Console Application

[kls_kumar]

Hi All,

 

I wrote a sample application to extract the messages and attachments from a .pst file using VB.Net which is working fine. Now i am trying to web service enable this and when i added an operation in .asmx File

 

<WebMethod(), System.Web.Services.Protocols.SoapRpcMethod()> _

Public Function extractPST(ByVal fileName As String) As String

Dim readPST As ReadPST

readPST = New ReadPST

readPST.readPST(fileName)

Return "success"

End Function

 

And i have a class ReadPST.vb which has the code

 

Sub readPST(ByVal fileName As String)

Dim i As Integer

Dim objOutlook As New Outlook.Application

' Dim objNS As Outlook.NameSpace = objOutlook.Session

Dim myNameSpace As Outlook.NameSpace = objOutlook.GetNamespace("MAPI")

'Dim file As New System.IO.StreamWriter("c:\test.html")

' Add the .pst File to the Name Space

myNameSpace.AddStore(fileName)

...........

 

And when i tried to debug the code i am getting a 500 Error at the Line

Dim myNameSpace As Outlook.NameSpace = objOutlook.GetNamespace("MAPI")

 

How can i resolve this..

 

Thanks a lot
