I'm making a hangman game. For some reason I'm able to disable buttons after their clicked if their in the word. If the button clicked isn't in the word I want to be able to set its property to invisible.....here's the code....



Public Class Form1
    Inherits System.Windows.Forms.Form


    Dim strWord As String


 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        strWord = InputBox("Please enter a word for the user to guess.")
        txtWord.Text = underscore(strWord.Length, "")
        MessageBox.Show("The word is " & CStr(strWord.Length) + " letters long.")

End sub

 Private Function underscore(ByVal wordlength As Integer, ByVal undscore As String) As String

        For wordlength = 0 To wordlength - 1
            underscore += "_ "
        Next

        Return underscore


    End Function

Private Sub btn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnQ.Click, btnP.Click, btnO.Click, btnN.Click, btnM.Click, btnL.Click, btnK.Click, btnJ.Click, btnI.Click, btnH.Click, btnG.Click, btnA.Click, btnB.Click, btnC.Click, btnD.Click, btnE.Click, btnF.Click, btnR.Click, btnS.Click, btnT.Click, btnU.Click, btnV.Click, btnW.Click, btnX.Click, btnY.Click, btnZ.Click

        Dim btn As Button = CType(sender, Button)
        Dim indx As Integer
        Dim i As Integer






        If Not btn.Text = "" Then
            indx = GroupBox1.Controls.IndexOf(btn)
            For i = 0 To strWord.Length - 1

                If strWord.Substring(i, 1) = btn.Text Then
                    strWord.Replace("_"c, btn.Text)

                    txtWord.Text = txtWord.Text.Substring(0, i) & btn.Text & txtWord.Text.Substring(i + 1).Replace("_"c, " "c)





                 



                    If btn.Enabled = True Then
                        btn.Enabled = False
                    Else
                        btn.Visible = False




                    End If


                End If


            Next i
        End If

    End Sub

End Class

Make a boolean flag and toggle it if you find a match.  Then when you're all done act on that flag:

        Dim found As Boolean = False
        Dim btn As Button = CType(sender, Button)
        Dim indx As Integer
        Dim i As Integer

        If Not btn.Text = "" Then
            indx = GroupBox1.Controls.IndexOf(btn)  ' <------ where are you using this?
            For i = 0 To strWord.Length - 1
                If strWord.Substring(i, 1) = btn.Text Then
                    found = True
                    strWord.Replace("_"c, btn.Text)     ' <------ this DOESN'T do anything!
                    txtWord.Text = txtWord.Text.Substring(0, i) & btn.Text & txtWord.Text.Substring(i + 1).Replace("_"c, " "c)      
                End If
            Next i
            If found Then
                btn.Enabled = False
            Else
                btn.Visible = False
            End If
        End If
