ID: Q192435

The information in this article applies to:

Collaboration Data Objects (CDO), versions 1.2, 1.21
Collaboration Data Objects Rendering Library, version 1.2

SUMMARY

This article contains sample code that used Collaboration Data Objects (CDO) to render the messages in the Sent Items folder to an Active Server Pages (ASP) page.

MORE INFORMATION

This is an example of how you can render the contents of a Messaging Application Programming Interface (MAPI) folder to a Web browser using an ASP page script written in the Visual Basic Scripting Edition and CDO.

Copy and paste the following code to an ASP page. Modify the variables that set the server and mailbox to appropriate values. This code requires Microsoft Exchange Server version 5.5.

Sample Code


   <%@ LANGUAGE="VBSCRIPT" %>
   <HTML>
   <HEAD><TITLE>Sent Items Display</TITLE></HEAD>
   <BODY BGCOLOR=SILVER>
   <%

   'CONTAINER CONSTANT
    CONST CdoClassContainerRenderer  = 3
    CONST CdoClassObjectRenderer  = 2

   'RENDERSTYLE CONSTANTS
    CONST CdoFolderContents = 1
    CONST CdoFolderHierarchy = 2

   '===== Default Folder Constants ========
   'These constants are passed into the Session.GetDefaultFolder()
   'method to return their respective folders.

    CONST CdoDefaultFolderCalendar = 0
    CONST CdoDefaultFolderInbox = 1
    CONST CdoDefaultFolderOutbox = 2
    CONST CdoDefaultFolderSentItems = 3
    CONST CdoDefaultFolderDeletedItems = 4
    CONST CdoDefaultFolderContacts = 5
    CONST CdoDefaultFolderJournal = 6
    CONST CdoDefaultFolderNotes = 7
    CONST CdoDefaultFolderTasks = 8
    CONST CdoDefaultFolderTotal = 9

   ' 2 - Render a column of data all in the same fashion.

   '   objColumn.RenderUsing = "<font color=blue>%value%</font>"

   'Render the object
    Response.write(objCRenderer.Render(CdoFolderContents))

   'Clean up Session & Rendering Objects.
    set objsession = nothing
    set objrenderapp = nothing
