Hi, I'm creating a game called Walk the Plank for my college course (for the 2nd time after failing last year), and I'm struggling with control arrays.

The form I have has the letters of the alphabet on a control array named cmdAlpha, and a hidden word is contained in a series of labels that are in another control array named lblLetter. The idea is to guess what letters are in the word by clicking the corresponding letter, and the program then searches through the lblLetter to see if it is in the word.

What should happen is if the letter is in the word, it replaces the asterisk, and the player continues guessing. If the guess is wrong, a message box comes up telling so, and the player loses 10 points from a 140 score total.

But what does happen is the error message appears whether the letter is in the word or not. See if you guys can fathom it out because I can't

Code:

Dim LetterPos, WordSize, MyLoop As Integer

Private Sub cmdAlpha_Click(Index As Integer)

cmdAlpha(Index).Enabled = False

strLetter = cmdAlpha(Index).Caption

'MsgBox strLetter

LetterPos = InStr(lblLetter(0).Caption, strLetter)

'MsgBox LetterPos

If LetterPos > 0 Then

lblLetter(LetterPos).Caption = strLetter

Else

MsgBox "Wrong. Have another try.", vbCritical

End If

End Sub

Thanks in advance, you guys helped me out a lot last year and I came here first for help.

I tried to use that, I understand what it is meant to do, but for some reason the label just doesn't recognise what I've clicked and is returning the incorrect msgbox everytime.

A common error I keep getting aswell is that I have 12 labels in the lblLetter control array, and 26 buttons in the cmdalpha array. But if I click a letter that has an index higher than the number of labels, it doesn't like it. eg "Control array element 16 doesn't exist."

The code I posted tested just fine for me and I never got any of the errors you're talking about. Maybe you could post your code and we can see where the problem lies.
