this code is design to enable scrolling with the mouse wheel in excel comboboxes placed on a worksheet(not userforms)
written by: Jaafar Tribak

for some reason this code only works on some computers
the computers this code didnt work in are:
win 10 office 2016 64bit
win 7 office 2013 32bit
although it did work in a machine running
win 10 office 2010 64bit

i dont understand why, the code just fail to hook the mousewheel to the combobox
if someone can offer a fix i will much appreciate it



code in standard module:

Excel Facts

What did Pito Salas invent?
Pito Salas, working for Lotus, popularized what would become to be pivot tables. It was released as Lotus Improv in 1989.
this code is design to enable scrolling with the mouse wheel in excel comboboxes placed on a worksheet(not userforms)
written by: Jaafar Tribak

for some reason this code only works on some computers
the computers this code didnt work in are:
win 10 office 2016 64bit
win 7 office 2013 32bit
although it did work in a machine running
win 10 office 2010 64bit

i dont understand why, the code just fail to hook the mousewheel to the combobox
if someone can offer a fix i will much appreciate it

Hi Ohad1997,

I 've just seen this post and made the following changes .. If you can confirm that the following update is working it will be great.

Workbook example

Code:
Option Explicit

Type POINTAPI
    x As Long
    y As Long
End Type

Type RECT
    Left As Long
    Top As Long
    Right As Long
    Bottom As Long
End Type

Type MSLLHOOKSTRUCT
    pt As POINTAPI
    mouseData As Long
    flags As Long
    time As Long
    dwExtraInfo As Long
End Type
