VBA UserForm MouseScroll

MouseScroll is a VBA Project that allows Mouse Wheel Scrolling on MSForms Controls and Userforms but can also be extended for clicks, double-clicks and movement inputs.

Multiple forms are tracked simultaneously. Just call the EnableMouseScroll for each form.

Installation

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

• MouseScroll.bas
• MouseOverControl.cls

Usage

In your Modal 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 in the Form's Terminate Event for extra safety:

Private Sub UserForm_Terminate()
    DisableMouseScroll Me
End Sub

Notes

• Hold Shift for Horizontal Scroll and Ctrl for Zoom
• The Mouse Hook will not work with Modeless Forms (Modal only)
• No need to call the DisableMouseScroll method. It will be called automatically (from the MouseScroll.bas module) when the Form's Window is destroyed
• Multiple forms are now tracked simultaneously and the mouse is unhooked automatically only when no forms are being tracked
• You can download the available Demo Workbook for a quick start

Other Controls

• ListView, TreeView control
  • Requires a reference to Microsoft Windows Common Controls
  • The value of the compiler constant DETECT_COMMON_CONTROLS (inside MouseOverControl.cls) needs to be set to a value of 1
• WebBrowser control
  • Requires a reference to Microsoft Internet Controls for the main control
  • Requires a reference to Microsoft HTML Object Library for the HTMLDocument control that tracks the onmousemove event
  • The value of the compiler constant DETECT_INTERNT_CONTROLS (inside MouseOverControl.cls) needs to be set to a value of 1
