Keep a variable which keeps track of the last value, then compare in the Scroll event, and update the variable to the new value

Private lastValue As Integer

Private Sub TrackBar1_Scroll(sender As Object, e As EventArgs) Handles TrackBar1.Scroll
    Dim change = TrackBar1.Value - lastValue
    If change > 0 Then ' increasing

    ElseIf change < 0 ' decreasing

    Else ' stayed the same
    
    End If
    lastValue = TrackBar1.Value
End Sub

Solution 3:[3]

You could add a handler on the TrackBar.ValueChanged Event. This may be sufficient for your needs if you don't care about the previous value. The difference with the Scroll event:

Occurs when the Value property of a track bar changes, either by movement of the scroll box or by manipulation in code.
