VB Scroll Bar Half Percentages

[JasonMaybe]

Hoping someone can help me out with a VB question.

I have a scroll bar that I need to have increase / decrease by half a percentage.

Min is 5
Max is 15
Start Display Value is 10

So far all I have been able to come up with is this, but it only increases / decreases the number by 1% instead of .5%.

Private Sub RateHScrollBar_Scroll(sender As System.Object, e As System.Windows.Forms.ScrollEventArgs) Handles RateHScrollBar.Scroll
Dim RateDouble As Double = RateHScrollBar.Value / 100

RateTextBox.Text = RateDouble.ToString("P1")
End Sub

Form with : Command1, ProgressBar1 and Label1

Private Sub Command1_Click()
   With ProgressBar1
      If .Value < 15 Then .Value = .Value + 0.5
      Label1.Caption = .Value
   End With
End Sub
 
Private Sub Form_Load()
   With ProgressBar1
      .Min = 5
      .Max = 15
      .Value = 10
   End With
End Sub
