mid function problem

i have just started learning vb at college, my first assignment is make the game hangman. i have made the command buttons into control arrays with each caption a letter of the aphabet.

what i want the program to do is search the chosen word and check if the letter chosen(by command button) is in there.
i am using the mid function, but keep getting errors. my code is as follows

i will appreciate any help as i am still new to this.

Private Sub cmdLetter_Click(Index As Integer)
cmdLetter(Index).Enabled = False
guess = txtGuess.Text
Let guess = Chr(Index + 65)
For i = 0 To Len(answer)
If Mid(answer, i, 1) = guess Then
txtGuess.Text = guess

wrong = wrong + wrong = 1

Else
If wrong = 1 Then ln1.Visible = True
ElseIf wrong = 2 Then ln2.Visible = True

Else:
If wrong = 3 Then ln3.Visible = True
Else
If wrong = 4 Then ln4.Visible = True
Else
If wrong = 5 Then Sh1.Visible = True
Else
If wrong = 6 Then ln5.Visible = True
ElseIf wrong = 7 Then ln6.Visible = True
ElseIf wrong = 8 Then ln7.Visible = True
ElseIf wrong = 9 Then ln8.Visible = True
ElseIf wrong = 10 Then ln9.Visible = True

Next

try

Code:

---

For i = 0 To Len(answer)-1

---

also what is this?

wrong = wrong + wrong = 1

Why not just use the InStr() function?

VB Code:

If InStr(variablename, character) Then

if you just need to check if the letter is in the word....

then use Instr()

If Instr(Word,Guess) then
Yes...
Else
No....
End if

Careful... it's spiked. :eek:

i have tried that, its still not working, what am i doing wrong ?

Private Sub cmdLet_Click(Index As Integer)
Dim word, temp, guess As String
Dim i, j, k As Integer

cmdLet(Index).Enabled = False
word = txtInput.Text
guess = Chr(Index + 65)
If InStr(word, guess) Then
txtOutput.Text = txtOutput + guess

Else
MsgBox "yes"
End If

End Sub

Here's a better way to do the number wrong processing.

VB Code:

Select Case wrong
            Case 1
                ln1.Visible = True
            Case 2
                ln2.Visible = True
            Case 3
                ln3.Visible = True
            Case 4
                ln4.Visible = True
            Case 5
                sh1.Visible = True
            Case 6
                ln6.Visible = True
            Case 7
                ln7.Visible = True
            Case 8
                ln8.Visible = True
            Case 9
                ln9.Visible = True
            Case 10
                ln10.Visible = True
        End Select

I don't know what that sh1 is all about, but if that should really be ln5 then I suggest you change the lines into a control array. If you did that then the above could be reduced to

VB Code:

lnLine(wrong).Visible = True

I also don't understand what txtInput is used for. Are you asking the user to type in his guess? Why not just use the caption of the command button that is clicked?

What is not working? BTW, when you Dim like this

Dim word, temp, guess As String
Dim i, j, k As Integer

only guess and k are defined the way you want. The others are left as variants. You should do
Dim word As String
Dim temp As String
etc., or
Dim word As String, temp As String

thanks for that martin. that code will be useful to me. the txtinput box is for the player 1 to type in a word, player 2 has to guess the word by pressing the cmdLet array, if that letter exists in the word then display in txtoutput, else draw a line

Your Index + 65 results in uppercase letters, so do this when checking the guess

word = UCase(txtInput.Text)
