VB program flow, forgot how to get it going

Hi all,

It's been a really long time since I've done VB and I was never any good at it.

I'm trying to write a simple program with two buttons and a label. The two buttons are Yes and No. The label will ask a question.

I'm having trouble getting it to flow, for example:

Are you over 21? User clicks Yes.
Are you a male? User clicks No.
Is your name Jane? User clicks Yes.
etc.

I have some code below that doesn't work at all. I forget what I'm missing in order for this to work, obviously calling the MainFlow sub would be a start but I can't even remember how to do that or if that's possible in VB. Maybe I'm mixing up my languages, I don't know!

I had it working with out the MainFlow sub but after 1 click it would just stop working.



Thanks,
Primus
Public Class Form1
 
    Dim BtnOne As Boolean = False
 
    Dim BtnTwo As Boolean = False
 
    Declare Sub Sleep Lib "kernel32" (ByVal milliseconds As Long)
 
 
    Public Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click
 
        BtnOne = True
 
    End Sub
 
    Public Sub btn2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn2.Click
 
        BtnTwo = True
 
    End Sub
 
    Public Sub MainFlow()
 
        If BtnOne = True Then
 
            lbl1.Text = "Are you a male?"
 
            BtnOne = False
 
            If BtnOne = True Then
 
                lbl1.Text = "Is your name Jane?"
 
            End If
 
        ElseIf BtnTwo = True Then
 
            lbl1.Text = "Alright, then you can't continue"
 
            Sleep(5000)
 
            End
 
        End If
 
    End Sub
 
End Class

Create a New Project with lblQuestion, btnYes and btnNo:
Public Class Form1
 
    Private Class Prompt
        Public Question As String
        Public CorrectAnswer As Boolean
    End Class
 
    Private CurrentPrompt As Prompt
    Private Prompts As New List(Of Prompt)
    Private PromptEnumerator As System.Collections.Generic.List(Of Prompt).Enumerator
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Prompts.Add(New Prompt() With {.Question = "Are you over 21?", .CorrectAnswer = True})
        Prompts.Add(New Prompt() With {.Question = "Are you a male?", .CorrectAnswer = False})
        Prompts.Add(New Prompt() With {.Question = "Is your name Jane?", .CorrectAnswer = True})
        PromptEnumerator = Prompts.GetEnumerator
        NextPrompt()
    End Sub
 
    Private Sub NextPrompt()
        If PromptEnumerator.MoveNext Then
            CurrentPrompt = PromptEnumerator.Current
            Label1.Text = CurrentPrompt.Question
        Else
            MessageBox.Show("You Passed!")
        End If
    End Sub
 
    Private Sub CheckAnswer(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnYes.Click, btnNo.Click
        Dim Answer As Boolean = (sender Is btnYes)
        If Answer = CurrentPrompt.CorrectAnswer Then
            NextPrompt()
        Else
            Me.Close()
        End If
    End Sub
 
End Class
