I am writing a noughts and crosses game and everything works but the checkwinner sub routine, so basically if someone gets three X's or O's in a row then a message box pops up saying either X has won or O has won.Below is what I have written in the sub routine.

I am using sockets to send message between computers. I send the messages alright. What I want is when the message "x0x" comes, the client must be closed within 5 minutes. Teh admin can cancel the request by sending message "-xx" as well. The routine that checks for incoming connections and accepts messages uses WHILE TRUE...END WHILE since it must always listen. Once I get a message, I need to fire a timer control or other that fires within 5 minutes. But the program cant leave the WHILE TRUE at all. If i exit it early, the timer fires and the program does get exit. How do I fire the timer or other routine while still the WHILE TRUE routine checks for incomin connections and messages?
View 5 Repliesis there any way to reference a particular code routine in VB.net external to the current loop/routine?Example:
If Var01 < 5
[Routine A]
Else
[Routine B]
End If
where Routine A and Routine B are code sequences at the end of the entire program -- such as outside of the current sub or class? The idea would be to reference an otherwise repetitive code.
I am programming the board game Sequence in vb 2010 and I have gotten to the point where I now need to figure out if someone has won or not
Here is a link to the game Sequence and it's rules: [URL]
I have looked at How to find the winner of a tic-tac-toe game of any size ? which is similar to my problem but gets very complicated if I wanted to try and migrate the idea to Sequence.
I am wondering if anyone has any ideas on how to tell if there is a winner?
The only way I can think of is keep a list of all the possible winning positions and I would not like to do that.
I have a sub routine where I pull in information from a database. I want to use variables from this sub routine in another sub routine. I tried making everything public but it doesn't want to be friendly and share.
Dim strEmail as String
Public Sub readDB()
strEmail = "whatever@doohikcy.com"
[Code]....
The readDB would read the database and set the variables and do whatever it needs to do. Then when they submit the form it would e-mail the form to whatever the email address was.
i have a two-dimensional char array that holds the values of a tictactoe board.Each element holds a value of either 'X','O', or and you can access the values with something like TicTacToe[0][1]with the first bracket containing the row # and the second containing the column #.
Whats the best way to detect the winner of a TicTacToe game? I was thinking about just making a function like this Private Function checkWin(Byval TicBoard as Char[][]) as Integer 'Return 0 if no winner, 1 if Player 1 wins, and 2 if Player 2 wins End Function Any ideas? I want to avoid using 8 if-else statements since that seems pretty inefficient and sloppy
I AM HAVING PROBLEMS WITH GETTING THIS PROGRAM TO DISPLAY THE WINNING MESSAGE. PLEASE ONLY REPLY WITH HELPFUL SUGGESTIONS HERE IS THE CODE I HAVE DONE
Public Class Form1 Dim flag As Boolean = False Private Sub Buttons(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click, Button2.Click, Button3.Click, Button4.Click, Button5.Click, Button6.Click, Button7.Click, Button8.Click, Button9.Click
If flag = False Then
DirectCast(sender, Button).Text = "X"
flag = True

In our program we track the moves in arrays by columns 0 means empty, 1 means black, 2 means red so it would look like this for example
column1(0) = "1"
column1(1) = "2"
column1(2) = "2"
column1(3) = "1"
column1(4) = "0"
column1(5) = "0"
for column 1, and we have seperate arrays for each column (7 in all) but they all have the same values 0,1, or 2 so how can we make it check the arrays and their values and detect a winner?
What would be the best way to add a progress bar to this routine so that it corresponds with the progress bar?[code...]

Code:

I was looking for something send keystrokes and I found this helpful routine SendKeys that I can use in a VB Script. I wanted to have "Right Control Key + (Scroll Lock & Scroll Lock)" sent to the machine. Essentially, having the Right Control Key pressed, I need Scroll Lock pressed twice. Here is what I tried:
set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.SendKeys"^({SCROLLLOCK}{SCROLLLOCK})"
I have the following code:
Private Sub Exceptionquery()
Dim connection As System.Data.SqlClient.SqlConnection
Dim connectionString As String = "Initial Catalog=mdr;Data Source=xxxxx;uid=xxxxx;password=xxxxx"
[code]....
I get the error Invalid Object name 'Scratchpad3' on this line:
adapter.Fill(ds)
I have tried to debug this and can see that the query is correct, that the values that are being passed to the sql server are correct but it doesnt look like my code is firing off the Exceptionquery Sub. I thought to call a sub all you had to enter was the name of the sub such as this line:
Exceptionquery()
I have also verified that the mapping of the buttonclick event is mapped correctly. I have other subs that I am calling in almost the same way and those work.
I know there are several libraries of code out there that can parse CSV files according to the standard, but, for various reasons, I need one simple routine (not an entire library) that parses a CSV into a DataTable or array. Does such an animal exist or is it extinct? (Preferably C# but i can translate vb.net too)

I am new to vb.net and am trying to design a routine that will allow the user to search for a record and return the results in a datagrid. Then double click on a row within the datagrid to view a more detailed form. I have been able to build the search form but am having problems with the double click event.I found a sample application on the Microsoft web site which is doing this on a smaller scale. The sample is built on the Northwind sql database and searches the customer table when you double click a row in the datagrid the following Microsoft code runs and opens a detailed form.

View 2 RepliesI have a service that i believe has a memory leak in one particular sub routine but I cannot find out why.The routine writes data to an opc server every second. It receives a command via tcp, connects to the database for verification of signals and writes the data. When it completes it writes a message back. I am disposing of everything i can think of but for some reason when I check it in the morning then memory has increased dramatically and the cpu usage goes up to 50%. this only happens to the service when I start the client application that sends the data so i know it has to be in this routine.

Isn't there a way in VB to pass an array literal? Say the subroutine ask for an array of integers and you have just one. Can't you do something like
DoSomething({MyNum})
instead of
Dim MyNums as Integer() = {MyNum}
DoSomeThing(MyNums)
I'm thinking I'm just missing some adornment to the array literal inorder pass it.
