I use scrollbar for scroling canvas . The following example.

In Event ValueChanged of scrollbar. i’m put
If Me.Enabled Then
Canvas7.Top = Me.Top - Me.Value 'Scrollbar min/max is set: 0 to (cvsSettings.Height - scrSettings.Height)
End If

In Event MouseWheel of canvas .Im’put
ScrollBar1.Value = ScrollBar1.Value + deltaX

You still use canvas.scroll in response to the scrollbar.
