Jscript：

<script language="JScript">
    function fnFolderItemsItemJ()
    {
        var objShell = new ActiveXObject("shell.application");
        var objFolder;
        var ssfWINDOWS = 36;
        
        objFolder = objShell.NameSpace(ssfWINDOWS);
        if (objFolder != null)
        {
            var objFolderItems;
            
            objFolderItems = objFolder.Items();
            if (objFolderItems != null)
            {
                var objFolderItem;
                
                objFolderItem = objFolderItems.Item(objFolderItems.Count - 1);
                alert(objFolderItem.Name);
            }
        }
    }
</script>

VBScript：

<script language="VBScript">
    function fnFolderItemsItemVB()
        dim objShell
        
        set objShell = CreateObject("shell.application")
        if (not objShell is nothing) then
            dim objFolder
            dim ssfWINDOWS
                
            ssfWINDOWS = 36
            set objFolder = objShell.NameSpace(ssfWINDOWS)
            if (not objFolder is nothing) then
                dim objFolderItems
                        
                set objFolderItems = objFolder.Items()
                if (not objFolderItems is nothing) then
                    dim objFolderItem
                    
                    set objFolderItem = objFolderItems.Item
                        if (not objFolderItem is nothing) then
                            alert(objFolderItem.Name)
                        end if
                    set objFolderItem = nothing
                end if
                set objFolderItems = nothing
            end if
            set objFolder = nothing
        end if
        set objShell = nothing
    end function
</script>

Visual Basic：

Private Sub fnFolderItemsItemVB()
    Dim objShell   As Shell
    Dim objFolder  As Folder
    Dim ssfWINDOWS As Long
    
    ssfWINDOWS = 36
    Set objShell = New Shell
    Set objFolder = objShell.NameSpace(ssfWINDOWS)
        If (Not objFolder Is Nothing) Then
            Dim objFolderItems As FolderItems
            
            Set objFolderItems = objFolder.Items
                If (Not objFolderItems Is Nothing) Then
                    Dim objFolderItem As FolderItem
                    
                    Set objFolderItem = objFolderItems.Item("NOTEPAD.EXE")
                        If (Not objFolderItem Is Nothing) Then
                            Debug.Print objFolderItem.Path
                        End If
                    Set objFolderItem = Nothing
                End If
            Set objFolderItems = Nothing
        End If
    Set objFolder = Nothing
    Set objShell = Nothing
End Sub
