Label not displaying text in VB

Question

Is there a reason why my code is not displaying the text in AnswerText.Text?

    Dim EquationValues() As String

    ' Split the array into a string array based on blank spaces
    EquationValues = DisplayTextBox.Text.Split(" "c)

    ' Declaring an integer as a counter for the loop
    Dim LoopCounter As Integer = 0

        ' Setting a for loop on the array and performing the operations
    For LoopCounter = 0 To EquationValues.Length - 1
        If EquationValues(LoopCounter) = "/" Then
            AnswerTextBox.Text = EquationValues(LoopCounter - 1) / EquationValues(LoopCounter + 1)
        End If

        If EquationValues(LoopCounter) = "*" Then
            AnswerTextBox.Text = EquationValues(LoopCounter - 1) * EquationValues(LoopCounter + 1)
        End If
    Next

Shouldn't you exit the look if one of the IF's condition is matched? — Mo Patel, Feb 17 '13 at 00:16
Yes. Are you saying I should include an else if? It doesn't show up even when there is only one if statement — toilabav90, Feb 17 '13 at 00:17
I would imagine if there's no text than the if conditions aren't getting met. Can you stick a breakpoint where the values are set and make sure the code's getting hit? — Andrew Walters, Feb 17 '13 at 00:17
I don't remember much of VB but try add something in the line 'of Exit For' inside the IF — Mo Patel, Feb 17 '13 at 00:23
But if I do an 'Exit For' then it'll exit where I place it right? Would that matter since it's not even showing the answer in the first place — toilabav90, Feb 17 '13 at 00:34
I checked ur code in a VS it is working fine. http://www.fileconvoy.com/dfl.php?id=g5a005fa18855e8339992254998f4094f2d76f149a — syed mohsin, Feb 17 '13 at 01:40

EquationValues is an array, checking the length is not what I think you are looking for. You are looking for the count...the number of indices in the array...try

For LoopCounter = 0 To EquationValues.Count - 1

I answered a previous question of your's regarding string parsing mathematical equations (parsing string to equation with vb). That example handled * and /, perhaps that might have something of use for you.

Good Luck :)
