Hi Ben,

Do you have any sample code to bind Drop down list to the list of users
returned from a web service? Or do you have any other idea to do this?
I am struggling with binding this DD box to the AD users list?

My current code on Infopath OnLoad event is

Dim nodeusers As IXMLDOMNode =
thisXDocument.DOM.selectSingleNode("my:myFields/my:users")
Dim ds As DirectorySearcher = New DirectorySearcher
ds.SearchRoot = New DirectoryEntry("")
ds.Filter = GetFilterString()
ds.PropertyNamesOnly = True
ds.PropertiesToLoad.Add("name")
ds.SearchScope = SearchScope.OneLevel

'// (CacheResults) property by default is true
ds.CacheResults = True
ds.ReferralChasing = ReferralChasingOption.None
ds.Sort = New SortOption("name", SortDirection.Ascending)

         '// start searching
           Dim src As SearchResultCollection = ds.FindAll()
           nodeusers.text = src.Count.ToString()
           Dim sr As SearchResult

           For Each sr In src
                       'Struggling at this point
                       nodeusers.text = sr.GetDirectoryEntry.ToString
           Next

Private Function FormFilter(ByVal objectCategory As String, ByVal
filter As String)
           Dim result As String
           result = String.Format("(&(objectCategory={0})(name={1}))",
objectCategory, filter)
           Return result
       End Function

       Private Function GetFilterString() As String

          Dim filter As String = ""
           filter += FormFilter("user", "*")
           Return "(|" + filter + ")"
       End Function

Thanks in advance.
