I'm a newbie to VB and such, I'm currently working on a program that allows users to play the National Lottery. The program generates random numbers for a lucky dip, allows users to log in etc. The problem I'm having is the feature that allows users to input their own results and check them against the 'current results' (just a randomised list of numbers) and work out what prizes if any the user is entitled to.Now obviously there are many different combinations of which numbers are the same.Is there any way (short of writing an IF statement catering for each combination possible) I could check these results? Perhaps with the use of a loop? I don't know I'm very new to this.
I am not going to use this to make any money, it is for an MMORPG (game) so players can benefit.As the title says im looking to make a Random Number 'Lottery', in other words I would like to be able to have random numbers generated and recorded onto a webpage (i don't know if .html or .php is best) but if i could get it to run on an .exe in which people could download and run it would have all my information on, but i would need a way in which i could update it without them having to re-download every 5 minutes. (Perhaps it could connect to a database? I don't know)
Last time this forum was the most helpful in solving my problems in vb 2005?This time I am writing a "lottery number picking" program. The program randomly picks 7 numbers from 39, with pre defined conditions on the strength of statistical data, and writes the possible combinations in a text file. It works fine, BUT- the program generates number of combinations I tell it to generate. With other words it works like
For i = 0 to 1000 generate_number() Next i
So this way I get 1000 combinations. how can I make the program generate all the possible combinations by itself?For example:
Do while (not reached the last combination) generate_number() Loop
While I don't know exactly how many combinations there are, I have a slight problem knowing which the "last" combination is.
I am developing an application that automatically checks player numbers in the Irish Lottery.
The code below checks each players 3 numbers against the six drawn numbers and reports on matching numbers and winnings. Each players information is stored in a specialised.string.collection in my.settings as shown below
Susan,3,18,26,2 Colin,4,16,28,1
The following checks the numbers but only the first item in the collection is being displayed in the multiine textbox.
Me.txtDrawInformation.Text = "Player results for " & drdate & vbCrLf & vbCrLf Dim player As New ArrayList For Each item In My.Settings.Wednesday
Making a program that generates random numbers for a "Lottery" (really for homework). Four different types of games and must show up on the GUI when click generate. My question is do you have to have different dim randomObject As New Random() for every Sub to produce different numbers? Every single type of game has different range of number. The Sub needs to return the results back as a string. If I request the method each time will I get a different number back from the range? Here is what I have but just so lost.
Public Class LotteryNumberGenerator Dim randomObject As New Random() Private Sub genButton_Click(ByVal sender As System.Object, ByVal e As
I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
As an update rolls out in one of my applications, I would like to implement an update checker. My situation is that, when a user clicks a drop down item called "Check for Updates", I want it to check for updates. My application is simple, I don't publish. I upload to a mediafire and put the download link to my blog. The only file I need in my application has always been the .exe file of the application itself. My question is, what is the simplest and best way to implement a update checker?
Example:User is using v1.1 and checks for updates. He clicks the "check for updates" and a popup shows up with yes, update available and is a msgbox yes or no. Yes, would allow the user to download the update. No, closes the msgbox. If there is no update available, then a msgbox shows "You have the current version". If the user is offline or cannot check I would like to have an exception to show why he cannot check.Basically, working with the download aspect and everything else is familiar to me but I have no idea how I can check.
Try My.Computer.Network.DownloadFile("downloadurl", "downloadlocation.fileextension") Catch ex As Exception MsgBox(ex.Message) End Try
I am a newbie to VB.Net. Before, I did programming in PHP. I made a spell checker in PHP which splitted a big string into single word by spaces, checked if the word is there in the dictionary, if not, it highlighted it and gave some suggestions when a user clicks on it. I want to make the same thing in VB.Net.
I am using vb.net 2010, trying to generate simple classes with properties using T4 from database. Sometimes I get an error that some string is not a valid property name because it is a vb keyword.

I am writing a Product key checker for Windows vista and 7, well it works well in both of these operating systems, but the only problem I encounter here is that, I cannot check vista keys when I run this program in 7..and vice versa. I declared the file as seen below.
Declare Auto Function PidGenX Lib "pidgenx.dll" (ByVal one As String, ByVal two As String, ByVal three As String, ByVal four As Integer, ByVal five As IntPtr, ByVal six As IntPtr, ByVal seven As IntPtr) As Integer
The thing I want to know is that how do you declare files, in the same directory as the exe file i.e. the app directory. I wish to have the 'pidgenx.dll' files of both operating systems in folders corresponding to their OS ie vista's pidgenx.dll in folder called Pack\Vista\pidgenx.dll and for 7's as \pack\7\pidgenx.dll

I was wondering if anyone has code available that would check for spelling using VB Forms? I work in an environment that has Office 2007 installed. I'm currently using some code that works, but leaves a bunch of WINWORD.EXE process open (one for each field I'm spell checking).
I should I do so that when a program is run, it automatically checks for conditions. If true, it will continue opening the form but if false, it opens another. What I've done is it goes directly to one form and if false it will close the form using me.hide() and loads a form using Form1.show(). Problem is, if the condition is false, both forms will open. What is the right way to do this?

Here is my code
Private Sub btnAnswer_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnevaluate.Click Dim Input As String If IsPalindrome(Input) Then txtAnswer.Text = "True"
