mousewheel smallchange 2

[three57m]

Does anyone know how to change hypetias code at thread222-902639 to allow a smallchange in scrolling. my understanding is that the default change is 3 lines can this be manipulated?

The default notch scroll is set in the driver. You can change it through

Start/Settings/Control Panel/Mouse/Wheel

I'm not aware of a way of changing it for a single specific thread or application.

You can use SystemParametersInfo function to change this setting.

Option Explicit
Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long, ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long
Const SPI_SETWHEELSCROLLLINES = 105
Const SPIF_SENDWININICHANGE = &H2
Const SPIF_UPDATEINIFILE = &H1
Const WHEEL_PAGESCROLL = -1

Private Sub SetMouseWheelScrollLines(Lines As Long)
SystemParametersInfo SPI_SETWHEELSCROLLLINES, Lines, 0&, SPIF_SENDWININICHANGE Or SPIF_UPDATEINIFILE
End Sub[/tt]

You can pass 0 to SetMouseWheelScrollLines function to disable scrolling. Passing the special value WHEEL_PAGESCROLL scrolls one whole page.

Just to clarify for the OP - this is a systemwide change
