VS 2008 - Code - Application That Automatically Checks Player Numbers In The Irish Lottery
Mar 12, 2010
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 wanted to warn the user that a text box only accepts 2 characters that are only numbers. I have the maxlength property of the textbox set to 2. I also need the user to be able to BS to correct the entry, but the BS goes over the maxlength.
Private Sub txtBusDay_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles txtBusDay.KeyPress
If txtBusDay.TextLength = 2 Then
txtMonthNum.Text = ""

I have a class that needs to check for errors in the data contained in a object.The routines that will check for errors could be implemented in concrete interfaces of supertype IErrorCheck. That way error checks can be discrete and added or removed from the class that requests the error checks.Each IErrorCheck implementation would be programmed against the supertype IErrorCheck (Strategy).But it would be nice not to recompile when checks are added or removed.Is there an accepted procedure for abstracting the error checks all the way out of the program, such as to read the checks from a file?

I would like to take blank secure stock paper and convert it in to a check.
I know you can get magnetic toner and print MICR.
The question is What is the actual font to use or should i get a package and send the data to it to print the check?
Has anybody done it successfully without having to resort to pre-printed checks.

I'm trying to design a small program for my home server that automatically updates an HTML page every time a new file is added to a certain directory.Example, say I already have 100 files in "C:Folder", and on the HTML page, all those files are listed in a table, and when you click on one of them, the file opens, say I add a new file to the folder, I want the program to automatically add that file to the list of other files, and put *NEW* next to it (newfile.txt *NEW*), and I would like it to say *NEW* for 5 days, so how would I go about making a program that does all that?

About some coding in visual basic.NET 2005. I was wondering if it was possible for code to be altered automatically if a certain event was triggered. For example; would it be possible for you to alter the following structure, say if a a button was pressed?
The structure is as follows:
Structure ClientDrawings
Public ClientID As String
Public Drawing_1 As String

I've almost completed my first VB.Net app which is a rewrite of an old vba app I wrote.The last part that I need to write is the timed events part. What I have in VBA is quite straightforward.Every 500ms the Timer event runs through, it checks if certain variables have been flagged and if so runs the relevent code? Code is nothing major, just updates a networked device.I've looked into timers in .net but it seems like there are various routes that I can go down.

im developing an application that constantly checks a particular webpage for changes in the page. im using the webbrowser.documenttext to read changes in the source, its working great. until when i tried to use webbrowser.refresh(), an ugly popup that says. "To display the webpage again, Internet Explorer needs to resend the information you've previously submitted.If you were making a purchase, you should click Cancel to avoid a duplicate transaction. Otherwise, click Retry to display the webpage again."

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)

Hi!
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'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 have a ListView object with the View property set to Details.I also have the CheckBoxes property set to True. Now, how do I get the user's input if they choose to check a box? Right now I am using the ItemCheck event, but that code runs even when I add something to the ListView object.What is the proper way to handle the event of when the user checks/unchecks a checkbox?

I have an issue with my project and I don't find the answer. I created a CBT project. The end result should be as follows: when the user inserts the CD (or DVD), the player will boot automatically. The media player and the video files are on the CD. When the media player is launched, the user can select the CBT he/she wants from a ListBox which will then play the file on the player. So far I build the player with all the necessry buttons but I have two things I can't find the solution for:1. how can I place the media player play the selected file from the listbox if the media files are on the same CD where the media player is located? As you can see on the below code, I manage to do that is the files are located on a drive (C:/ or D:/).2. I placed a FullScreen button which will expand the WMP to fullscreen mode but I can't figure out how to return it to the initial mode if pressing a key, for instance ESC.
