Detect if a Combo box is currently dropped?

Hi all,

Does anyone know a way to detect if a DataCombo is currently dropped?

Needs a timer and a combobox.

VB Code:

Option Explicit
Private Const CB_GETDROPPEDSTATE As Long = &H157
 
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" ( _
     ByVal hwnd As Long, _
     ByVal wMsg As Long, _
     ByVal wParam As Long, _
     lParam As Any) As Long
 
 
 
Private Sub Form_Load()
 
    Dim intFN As Integer
    For intFN = 0 To 25
        Combo1.AddItem "Index #" & intFN
    Next intFN
    
    Timer1.Enabled = True
    Timer1.Interval = 100
End Sub
 
Private Sub Timer1_Timer()
 
    Me.Caption = IIf(SendMessage(Combo1.hwnd, CB_GETDROPPEDSTATE, 0, 0), "Listbox is visible.", "Listbox is not visible.")
    
End Sub

Thanks Shawn N, but i'm afraid this doesn't work with the data combo...

Any other ideas?
