VBA UserForm MouseScroll

MouseScroll is a VBA Project that allows Mouse Wheel Scrolling on MSForms Controls and Userforms.

• Multiple forms are tracked simultaneously. Just call the EnableMouseScroll for each form
• Both MODAL and MODELESS forms are supported (starting 12-Oct-2023)!
• Debugging while the mouse is hooked is now supported (starting 12-Oct-2023)!
• This library can be extended for clicks, double-clicks and movement inputs
• Both vertical and horizontal scroll are supported. Hold down Shift for horizontal scroll and Ctrl for Zoom

Installation

Just import the following 2 code modules into your VBA Project:

• MouseScroll.bas
• MouseOverControl.cls

To avoid any issues with the CR and LF characters, it is best to download the available ZIP and then import the modules from there.

For anyone using specialized Mouse software please be aware that it might interfere with the mouse hook used in this project. For the following software, you only need to change some settings:

• X-Mouse Button Control (XMBC). See fix here
• StrokesPlus. See fix here

Usage

In your Userform use:

EnableMouseScroll myUserForm

For example, you can use your Form's Initialize Event:

Private Sub UserForm_Initialize()
    Me.StartUpPosition = 0
    Me.Left = Application.Left + Application.Width / 2 - Me.Width / 2
    Me.Top = Application.Top + Application.Height / 2 - Me.Height / 2

    EnableMouseScroll Me
End Sub

Not needed, but the following code can be added to the Form's Terminate Event:

Private Sub UserForm_Terminate()
    DisableMouseScroll Me
End Sub

Tracking of forms is done automatically by checking if the window is still valid and if the reference count of the form's object has any references left (except the internal ones used for raising events).

Notes

• You can download the available Demo Workbook for a quick start

Other Controls

• ListView, TreeView, WebBrowser etc. controls are supported without the need for any changes to the code
