move on to next set of arrays on button press

[andy1510]

i am working on a game in vb.net which is designed to ask the user a set of questions which are stored in multidimensional arrays. the user can answer the questions by clicking one of four buttons.

I currently have a set of buttons numbered 1-4, I also have a set of arrays but I am stuck making the game move on to the next set of questions.

the question is put in a text box and the answers are put in the four buttons, I need to be able to set the program to check if the button pressed if correct and if so move onto the next question.

heres my code so far

Public Class Form1

    Dim intQuestionNo As Integer
    Dim strQuestionInfo(15, 4) As String

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        intQuestionNo = 0
        txtQuestionNo.Text = intQuestionNo

        If intQuestionNo = 2 Then
            question2()
        End If

        strQuestionInfo(0, 0) = "how many colours on the UK flag?"
        strQuestionInfo(0, 1) = "1"
        strQuestionInfo(0, 2) = "3"
        strQuestionInfo(0, 3) = "5"
        strQuestionInfo(0, 4) = "7"

        strQuestionInfo(1, 0) = "which of these famous uk landmarks can be found in london?"
        strQuestionInfo(1, 1) = "Big Ben"
        strQuestionInfo(1, 2) = "Stonehenge"
        strQuestionInfo(1, 3) = "Hadrians Wall"
        strQuestionInfo(1, 4) = "The While Cliffs of Dover"

        strQuestionInfo(2, 0) = "What is the chemical composition of water?"
        strQuestionInfo(2, 1) = "H2"
        strQuestionInfo(2, 2) = "20"
        strQuestionInfo(2, 3) = "H20"
        strQuestionInfo(2, 4) = "02H"

        strQuestionInfo(3, 0) = "what is the largest state in the United states of America?"
        strQuestionInfo(3, 0) = "New York"
        strQuestionInfo(3, 0) = "Texas"
        strQuestionInfo(3, 0) = "Alabama"
        strQuestionInfo(3, 0) = "Alaska"

        strQuestionInfo(4, 0) = "What year did world war 2 end?"
        strQuestionInfo(4, 0) = "1944"
        strQuestionInfo(4, 0) = "1946"
        strQuestionInfo(4, 0) = "1948"
        strQuestionInfo(4, 0) = "1952"

    End Sub
    Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
        btnStart.Hide()
        intQuestionNo += 1
        If intQuestionNo = 1 Then
            question1()
        End If

    End Sub
    Sub question1()
        txtQuestion.Text = strQuestionInfo(0, 0)
        btnAnswer1.Text = strQuestionInfo(0, 1)
        btnAnswer2.Text = strQuestionInfo(0, 2)
        btnAnswer3.Text = strQuestionInfo(0, 3)
        btnAnswer4.Text = strQuestionInfo(0, 4)
    End Sub
    Sub question2()
        txtQuestion.Text = strQuestionInfo(1, 0)
        btnAnswer1.Text = strQuestionInfo(1, 1)
        btnAnswer2.Text = strQuestionInfo(1, 2)
        btnAnswer3.Text = strQuestionInfo(1, 3)
        btnAnswer4.Text = strQuestionInfo(1, 4)
    End Sub
    Sub question3()
        txtQuestion.Text = strQuestionInfo(2, 0)
        btnAnswer1.Text = strQuestionInfo(2, 1)
        btnAnswer2.Text = strQuestionInfo(2, 2)
        btnAnswer3.Text = strQuestionInfo(2, 3)
        btnAnswer4.Text = strQuestionInfo(2, 4)
    End Sub
    Sub question4()
        txtQuestion.Text = strQuestionInfo(3, 0)
        btnAnswer1.Text = strQuestionInfo(3, 1)
        btnAnswer2.Text = strQuestionInfo(3, 2)
        btnAnswer3.Text = strQuestionInfo(3, 3)
        btnAnswer4.Text = strQuestionInfo(3, 4)
    End Sub
    Sub question5()
        txtQuestion.Text = strQuestionInfo(4, 0)
        btnAnswer1.Text = strQuestionInfo(4, 1)
        btnAnswer2.Text = strQuestionInfo(4, 2)
        btnAnswer3.Text = strQuestionInfo(4, 3)
        btnAnswer4.Text = strQuestionInfo(4, 4)
 end sub

    Private Sub btnAnswer1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAnswer1.Click

    End Sub
End Class

I would suggest to pass the question number to the question presenter routine, an use the index to access the array:

Sub question(Byval intQuestionNumber as Integer)
        txtQuestion.Text = strQuestionInfo(intQuestionNumber , 0)
        btnAnswer1.Text = strQuestionInfo(intQuestionNumber , 1)
        btnAnswer2.Text = strQuestionInfo(intQuestionNumber , 2)
        btnAnswer3.Text = strQuestionInfo(intQuestionNumber , 3)
        btnAnswer4.Text = strQuestionInfo(intQuestionNumber , 4)
    End Sub

So calling the routine can be:

Private Sub btnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
        btnStart.Hide()
        intQuestionNo += 1
        question(intQuestionNo)
    End Sub

Maybe you also need to know wich button is the right answer for the question

Dim intRightAnswerButton as Integer = {3, 5, 4, 2, 1}  ' I'm not currently aware of the right answers :-)

So to load the current question you can add a Private variable for the class like

Private intRightAnswer as Integer = 0

and change the question() procedure like

Sub question(Byval intQuestionNumber as Integer)
        txtQuestion.Text = strQuestionInfo(intQuestionNumber , 0)
        btnAnswer1.Text = strQuestionInfo(intQuestionNumber , 1)
        btnAnswer2.Text = strQuestionInfo(intQuestionNumber , 2)
        btnAnswer3.Text = strQuestionInfo(intQuestionNumber , 3)
        btnAnswer4.Text = strQuestionInfo(intQuestionNumber , 4)
        intRightAnswer = intRightAnswerButton(intQuestionNumber)
    End Sub

Then add the necessary code to each button like

Private Sub btnAnswer1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAnswer1.Click
        If intRightAnswer = 1 Then
            intQuestionNo += 1
            question(intQuestionNo)
        End If
    End Sub

    Private Sub btnAnswer2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAnswer2.Click
        If intRightAnswer = 2 Then
            intQuestionNo += 1
            question(intQuestionNo)
        End If
    End Sub

and so on.

Hope this helps.
