what is the code to change the tool tip for the button in this example:
Private Sub AddToolbar()
Dim tbb As Object
On Error Resume Next
Toolbars("Test").Delete
On Error GoTo 0
Set oTB = Toolbars.Add(Name:="Test")
With oTB
.Left = 117
.Top = 186
Set tbb = .ToolbarButtons.Add(Button:=23, Befo=1)
tbb.OnAction = ThisWorkbook.Name + "!custommacro"
.Width = 200
.Visible = True
End With
End Sub

question 2
can you create/design a custom button in excel 2007?
if so, how?
