Private Declare Auto Function SendMessage Lib "user32.dll" ( _
ByVal hwnd As IntPtr, _
ByVal wMsg As Int32, _
ByVal wParam As Boolean, _
Optional ByVal lParam As Int32 = 0 _
) As Int32

Private Const CB_SETEXTENDEDUI As Int32 = &H155

' Disable F4.
SendMessage(Me.ComboBox1.Handle, CB_SETEXTENDEDUI, True)

For enabling F4, pass 'False' in the last parameter.
