Hi I am in a basic programming class right now and I am starting to understand it all, but I am stumped on one of my instructions. I am using VB2008 Express and my instruction is:

In guessing a letter, specify the string function you will need to use to determine which values of "?" in lblWord need to be replaced with the correct letter. I have no idea what I should be using here, any help is greatly appreciated Thank you

P.S. - In case it helps below is the code I already have:

Public Class frmMain
Public strLetterGuessed As String
Public strWordGuessed As String
Public strWordToGuess As String
Public strLettersGuessed As String
Public intNumTries As Integer = 0



'Copy code from SampleCode.txt here during Part 3




Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
Me.Close()
End Sub

Private Sub btnNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNew.Click
lblWord.Text = "??????? ?????"
btnGuessL.Enabled = True
btnGuessW.Enabled = True
btnSolve.Enabled = True
strWordToGuess = "BASSETT HOUND"
intNumTries = 0

End Sub

Private Sub btnGuessL_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGuessL.Click
txtLetter.Text = strLetterGuessed.ToUpper + ","
lblGuessed.Text = strLettersGuessed
intNumTries += 1

End Sub

Private Sub btnGuessW_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGuessW.Click
txtWord.Text.ToUpper()
txtWord.Text = strWordGuessed
intNumTries += 1
End Sub

Private Sub btnSolve_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSolve.Click
lblWord.Text = "BASSETT HOUND"
End Sub

Private Sub frmMain_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
