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

[toecutter]

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

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

Please see attached image

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.

        '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:

Dim x As Double

Select Case x
    Case Is >= 0.2

    Case Is >= 0.0

    Case Is >= -0.5

    Case Else

End Select

this would be perfect, thx
