Bug? Move text number to double

[atiaust]

Hi All,

Not sure if this a bug or I am missing something.

I have a textfield on a form, textField1.
If I enter '-1.0' into the textfield and use the following code:

dim newNum as double = textField1.text

This causes: java.lang.NumberFormatException: For input string: "-"

I assumed a 'double' could have a negative number?

Thanks

On further investigation the error occurs in the code below:

private Sub txtPayAmnt_TextChanged (Old As String, New As String)
    Dim newPay As Double = New
    If newPay <= 0 Then
        Main.dlg.ToastMessage("Can't input negative numbers",3000)
    End If
End Sub

This is not a bug. It fails after you enter the minus sign. '-' is not a valid number.

Change the code to:

If IsNumber(new) = False Or new < 0 Then
 '...
End If
