im creating a VB.net program that is basically tic-tac-toe. what i want to do is make it so when i click a checkbox, it will change the forecolor to blue and lock it. And then generate a random number between 1-9 and change the color of that # checkbox's forecolor to red, check it, and lock that also (like the computer playing its turn). Once someone gets 3 in a row, a message box should appear that says

Code:

---

str_winner & "has won the game!"

---

this is what i have so far :(

Code:

---

CheckBox1.BackColor = System.Drawing.Color.Blue

---

Hi,

VB Code:

Dim iNum As Integer
 
Public Sub SelectedNumber(strTemp As String)
     CallByName(Me, strTemp, CallType.Method)
End Sub
 
 
 Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged
        CheckBox1.BackColor = System.Drawing.Color.Blue
        (call randomise sub and store number in iNum)
        SelectedNumbers("sub" & cstr(iNum))
 End Sub
 
Public Sub Sub1()
        CheckBox1.ForeColor=System.Drawing.Color.Red
        CheckResult
End Sub
 
(Repeat this last sub for all 9 numbers.)
 
 
Private Sub CheckResult()
  Select Case True
    Case CheckBox1.ForeColor =System.Drawing.Color.Red
       Select Case True
          Case CheckBox2.ForeColor=System.Drawing.Color.Red
              Select Case True
                Case CheckBox3.ForeColor =System.Drawing.Color.Red
                   MessageBox.Show("A Winner")
          Case CheckBox4.ForeColor =System.Drawing.Color.Red

Go on repeating the select case's for each of the 8 directions.

when you say 'locked' i guess you mean to fix the box so that it can't be checked again? you could use the Enabled property and set it to false which will grey it out. Probably not what you want.

what you SHOULD do, or at least what I would do, is upon the checkbox.click event, check for the CheckState property and if it's checked, don't allow any action. that will keep anyone from unchecking it and not grey it out.

Also, when your AI picks a random number, i'm sure you know this, be sure to NOT include the boxes already checked. there are several ways to go about that also. Such as IF Checked, try to pick again or even in the subroutine that picks the random number, omit any checked boxes.

Just my .02 :D

also, the AI should not simply be to pick a random number and play its turn in that square. That isn't really AI at all... it should map out the BEST move to make

tic-tac-toe is rigged if you ask me though...

whoe ever goes first will ALWAYS win as long as they play the 3 outer corners

draw a tic tac toe board and play both x and o. which ever goes first, play any 3 outter corners and you will always win...

i did not know that about tic tac toe. neat.

Have O's first move be to put an O in the center and that doesn't hold true.

ok you obviously missed my point where i said if whoever goes first plays the OUTER CORNERS... I didn't say anything about playing the center... sure there are plenty of ways to NOT WIN. I said for whatever player goes first there is a guaranteed way for them to win :rolleyes: :rolleyes: :rolleyes:

Your missing the point. Not if O plays the center, then it is stalemate, X can't win either. X plays outer corner, O plays center. No matter which corner you put an X in now, it's gonna be a stalemate unless O is really really stupid. Try it.

X Bottom Left
O Center
X Upper left
O Middle left
X Middle Right
O Upper Center
X Bottom Center
O Bottom right

Stalemate

X Bottom left
O Center
X Upper Right
O Upper Center
X Bottom Center
O Bottom Right
X Upper left
O Middle Left

Stalemate

lol, i thought you meant if you start as first player and play the center. but yeah your right if second player plays the center it will stalemate. so its either first player wins each time, or stalemate each time

so its still a sham

Taxes, you should change your name to CallByName. That seems to be your answer to every question. :cool:

It's my new toy. I've been looking for something like for that since I lost Macro Substitution in Dbase. You're going to see me use it at every opportunity.:bigyello:


You guys making comments on Tic Tac Toe, it is NEVER possible to guarantee to win, no matter whether you go first or not.
If the first person goes in a corner, the second person MUST go in the opposite corner or the centre. It is ALWAYS possible to force a stalemate.

This is one game at which it is impossible to beat a computer.
