HOWTO: View Public Folder Contents from an ASP Page

ID: Q178552

The information in this article applies to:

Collaboration Data Objects (CDO), version 1.2

SUMMARY

This article describes how to view the contents of a Public Folder from an Active Server Page (ASP). This article contains sample code that demonstrates this technique.

MORE INFORMATION

A difference between viewing Public Folders in Visual Basic and from Visual Basic Script in an ASP page, is that in Visual Basic Script you need to use the GetFolder() method, which necessitates knowing the FolderID. (The error MAPI_E_FAILONEPROVIDER (8004011D) may occur if you attempt to traverse the folders instead.) If you do not know the FolderID, you need to determine the FolderID programmatically.

The following code looks for the "*Welcome to Public Folders*" folder in the "Public Folders" collection. Insert the following code into an ASP file and make appropriate modifications for server, mailbox, and folders:

Sample Code

   <%@ LANGUAGE="VBSCRIPT" %>

   <HTML>
   <HEAD>
   <META NAME="GENERATOR" Content="Microsoft Visual InterDev 1.0">
   <META HTTP-EQUIV="Content-Type" content="text/html;charset=iso-8859-1">
   <TITLE>Document Title</TITLE>
   </HEAD>
   <BODY>

   <!-- Insert HTML here -->
   <%
   CONST strServer      = "MyServer"
   CONST strMailbox     = "MyMailbox"
   Dim objSession
   Dim objMessages
   Dim objOneMessage
   Dim objInfoStores
   Dim objInfoStore
   Dim objTopFolder
   Dim objFolders
   Dim objSubFolder
   Dim objTargetFolder
   Dim strProfileInfo
   Dim i
   Dim bstrPublicRootID

   strProfileInfo = strServer & vblf & strMailbox
   Set objSession = Server.CreateObject("MAPI.Session")
   objSession.Logon , , , False, , True, strProfileInfo
   Set objInfoStores = objSession.InfoStores

   For i = 1 To objInfoStores.Count
    If objInfoStores.Item(i)= "Public Folders" Then
       Set objInfoStore=objInfoStores.Item(i)
       Exit For
    End If
   Next

   bstrPublicRootID = objInfoStore.Fields.Item( &H66310102 ).Value
   Set objTopFolder = objSession.GetFolder(bstrPublicRootID, _
               objInfoStore.ID)
   Set objFolders = objTopFolder.Folders
   Set objFolder = objFolders.GetFirst()

   Do Until objFolder.Name = "*Welcome to Public Folders*"
    Set objFolder=objFolders.GetNext()
   Loop

   Set objMessages = objFolder.Messages
   Response.Write("10 objMessages.Count = " & objMessages.Count _
         & "<br>")
   For Each objOneMessage in objMessages
     Response.Write("objOneMessage.Subject = " & _
            objOneMessage.Subject & "<br>")
     Response.Write("objOneMessage.Text = " & objOneMessage.Text & _
           "<br> <br>")
   Next

   objSession.Logoff
   Set objOneMessage = Nothing
   Set objMessages = Nothing
   Set objFolder = Nothing
   Set objTopFolder = Nothing
   Set objSession = Nothing
   %>
   </BODY>
   </HTML>
