Detecting Combo Box List Retraction

Question:
How would you detect the Retraction of a Combo Box Dropdown List in VB 4.0? I have a solution which claims to work under VB 3.0 and VB 2.0 using the SendMessage function in the user.dll file. user.dll does not appear to be on my system; is there an equivalent, or perhaps another way to solve my problem?

Answer:
I think I know the solution you are talking about -- it should work fine in VB 4.0 also, but you need to use the USER32 library since you are in Windows 95. Here is the correct declaration for the SendMessage API call in VB 4.0/32:

Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Long) As Long
