SUMMARY
This article describes how to view the contents of a Public Folder from an Active Server Page (ASP) page. 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" %>

    Document Title  

<%  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 _        & " ") For Each objOneMessage in objMessages Response.Write("objOneMessage.Subject = " & _           objOneMessage.Subject & " ") Response.Write("objOneMessage.Text = " & objOneMessage.Text & _          "  ") Next

objSession.Logoff Set objOneMessage = Nothing Set objMessages = Nothing Set objFolder = Nothing Set objTopFolder = Nothing Set objSession = Nothing %>    Microsoft provides programming examples for illustration only, without warranty either expressed or implied, including, but not limited to, the implied warranties of merchantability and/or fitness for a particular purpose.
