thats all i remember lol
ending is = nothing

---

How could i do this?

this is my code for the play now button right now. (im not sure what the gamedone thing is there for)

Code:

---

    Private Sub PlayAgainToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayAgainToolStripMenuItem.Click




        If GameDone = 1 Then
            GameDone = 0
        End If

---

Thanks alot, please reply asap, im leaving soon and need this for tomrrow :)

cya

I'm afraid that isn't even close to enough information to expect an answer. How do you play it the first time?

What do you mean?

I have a Play now button.. and i need the proper code for my app to basically Loop.

What info do you need more? my code?

Code:

To us your game is a black box. If you say here's my black box with a Play Again button. Now how do I wire it up to play again? If we don't know anything about what's inside the black box then how can we tell you how to make it do anything?

Now, playing again just means starting a new game. If you've already played one game then you've already started a new game so you should just be doing the same thing again.

^^What? im confused lol.

I would like it so that i can run it as a .exe and just press play again when the game is over.....

Do you want me to upload my program to somthing and you can have a look at it, if its a black box?

thanks

How about if you take a print screen of your GUI and post a picture for us, that might help.

Do you need to keep the results of the previous game?

It sounds to me like you might just need to clear the array that you store your moves in, and reset the buttons to their original state, this can be very easy.

Ok, here my array.

Thanks for the help everyone :)

http://i32.tinypic.com/2mi0r5g.jpg

Looks like what you need to do is clear all the buttons by setting the captions to "", then clear the TTT array.

eekkkkkk... im unfamiliar with that.

do you mind giving me a tiny step by step process in doing this?

again, thanks a lot this is great :)

Try this

vb Code:

Private Sub PlayAgainToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayAgainToolStripMenuItem.Click 
 
        Dim i As Integer
        Dim ii As Integer
 
        For i = 0 To 2
            For ii = 0 To 2
                chrTTT(i, ii) = ""
            Next
        Next
 
    btn00.text = ""
    btn01.text = ""
    btn02.text = ""
    btn10.text = ""
    btn11.text = "" 
    btn12.text = ""
    btn20.text = ""
    btn21.text = ""
    btn22.text = ""
 
    player = "X"
End Sub

Great. thanks for the code!!!

Im still recieving an error...

heres a pic. as you can see im getting the blue lines .

http://i32.tinypic.com/2yvt7w6.jpg

thanks alot, this is great ! :)

put your mouse over the wiggly line and itll tell you whats wrong ( as it says in the description at the bottom of the capture "its not declared"

when it comes to

vb Code:

btn00.text = ""
    btn01.text = ""
    btn02.text = ""
    btn10.text = ""
    btn11.text = ""
    btn12.text = ""
    btn20.text = ""
    btn21.text = ""
    btn22.text = ""

i always put that in a for each loop as its less code

vb Code:

for each ctrl as control in me.controls
if typeof ctrl is button then
ctrl.text = ""
end if
next ctrl

Thanks, it says both of them is not declared?
What do i do for the Player one?

And how do you use the loop your talking about?

THANKS ALOT EVERYONE!!

chrtt is declared in btnMoveMade_Click as a static variable, it should be public at the top of the code form so then you can use it in all subs. if you declare it in a sub, its not available anywhere else and itll say its not declared. the for each loop is added to my post above.

you see it right in the screen shot you posted

put both of these (remove from the sub too otherwise youll get an error saying its already declared) at the top of your code window and declare it public (will only be public for the form and not the whole app

vb Code:

Static chrTTT(2, 2) As Char     'store player moves
        Static player As Char = "X"     'X goes first

Thanks alot man, thats helping greatly :)

but i have a problem... i think i may be doing somthing wrong from the advie you guys are giving me... im still a newb to this and some of the stuff im still trying to figure out :P

anyways... the first game works... and then when i click "Play Again" is goes to a new game.... which is good, excpet the first move i make (X) it right away says Game over!... then i cant play, i only have the option to use X and after every square i use it says Game over.

Is there somthing i did wrong? i must have.

do you want a pic of my code? which part?

Thanks alot

cya

arrrrrrrrg.. well i got a buddy to help me out and fixed a couple of things, but neither of us can fix the game over bug when the play again button it pressed.

when you press play again and chose your first square it just says GAME OVER. which is not supposed to happen.

Heres my code now. thanks

Try setting the Text property of each button to Nothing rather than "" in the PlayAgainToolStripMenuItem_Click eventhandler.

vbcode Code:

Private Sub PlayAgainToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayAgainToolStripMenuItem.Click
        ReDim chrTTT(2, 2)
        For Each ctrl As Control In Me.Controls
            If TypeOf ctrl Is Button Then
                ctrl.Text = Nothing
            End If
        Next ctrl
        player = "X"
    End Sub

Just a suggestion. Make a sub like "StartNewGame" and move the code you have in the PlayAgainToolStripMenuItem_Click eventhandler to that sub. Now you can call the sub from the Form_Load event and also the PlayAgainToolStripMenuItem_Click eventhandler to start a fresh game. This now becomes your generic "Cleanup" routine.

Hope it helps,

Peace! :wave:

hey thanks alot man!!

can you explain a little more bout that coding you said?

this is my new code, is it right? how do i call the form? thanks

also please add my msn. [email protected] i think yahoo people can still talk to me.

Declare StartNewGame() like :

vbcode Code:

Private Sub StartNewGame()
    ReDim chrTTT(2, 2)
    For Each ctrl As Control In Me.Controls
        If TypeOf ctrl Is Button Then
            ctrl.Text = Nothing
        End If
    Next ctrl
    player = "X"
End Sub

Now you can use this routine to start a new game from any event.

vbcode Code:

Private Sub Form_Load (ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    StartNewGame()
End Sub

And also,

vbcode Code:

Private Sub PlayAgainToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PlayAgainToolStripMenuItem.Click
    StartNewGame()
End Sub

Simplifies things, doesnt it?

:wave: Peace! :wave:

thanks! it does make things easyer.... except im still having the same problem :(


when you press play again and chose your first square it just says GAME OVER. which is not supposed to happen.

I see that you have duplicate declarations.

1. Public chrTTT(2, 2) As Char 'In Class Form1
2. Static chrTTT(2, 2) As Char 'In Sub btnMoveMade_Click

Remove the Static declaration in the sub btnMoveMade_Click and see if that helps.

hmmm i get an error message wen i chose my first box then it highlights this dim in yello

Code:

---

Dim x As Integer = Val(index.Chars(0))

---

aahhhhhhhhhhhhhhhhhhhhhh.. i gotta wake up in 3 hours for school.

any other options hear?

thnx alot
