Um eine ComboBox bei Erhalt des Fokus automatisch aufklappen zu lassen, bedarf es
nur der API-Funktion SendMessage und einer Zeile Code im
GotFocus-Ereignis der ComboBox.

Option Explicit
Private Declare Function SendMessage Lib "user32" Alias _
"SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
ByVal wParam As Long, ByVal lParam As Long) As Long
Private Const CB_SHOWDROPDOWN = &H14F
Private Sub Form_Load()
Dim i As Integer
For i = 1 To 10
Combo1.AddItem "List-Eintrag " & i
Next i
Combo1.ListIndex = 0
End Sub
Private Sub Combo1_GotFocus()
SendMessage Combo1.hwnd, CB_SHOWDROPDOWN, True, 0
End Sub
