[RESOLVED] Less Then 0 but greater then (negative .5)

Making a traffic light color app and cannot figure out how to handle a negative value ( -0.5) to make a panels BackColor = Color.Yellow

Code:

---

 
  If CDbl(TxFrontThrustAfter.Text) < 0.0 And CDbl(TxFrontThrustAfter.Text) > -0.5 Then
            PnlFrontAfterThrust.BackColor = Color.Yellow
        End If

That code could be improved in various ways but it looks like it should do exactly what you want as it is. What's the actual problem?

thankyou, i am now thinking its due to below in a earlier sub.

Code:

---

        'REMOVES "-" VALUE FROM TEXTBOX
    If TxFrontThrustAfter.Text.Contains("-") Then
            'MessageBox.Show(TxFThrustBefore.Text)
            Dim Str As String = TxFrontThrustAfter.Text
            Str = Str.Replace(“-“, “”)
            TxFrontThrustAfter.Text = Str
            End If

---

Maybe you should be using a NumericUpDown in the first place, rather than a TextBox.

Also, I'm not sure whether this is appropriate in your context but you might consider a Select Case to determine the colour:

Code:

---

Dim x As Double

Select Case x
    Case Is >= 0.2

    Case Is >= 0.0

    Case Is >= -0.5

    Case Else

End Select
