Allow The User To Vote For Any Contestant Any Time By Entering The Last Name Of The Contestant"?
May 5, 2011
I am having much difficulty with it... heres what i have to do
"Write a program that allows users to vote on their favorite singer American Idol style. Your program should have the following features:
Your program should use a single listbox to display the names of the contestants and the number of votes for each contestant.
Use a class to hold the contestant�s first name, last name, and number of votes. The class should include a method to increment the contestant�s vote count by 1. Be sure to use property procedures for the first name, last name and number of votes properties.
Your program should read the names of contestants from an input file and display them in the listbox. You cannot make assumptions about how many contestants there will be in advance.
Your program should allow the user to sort the contestants by the number of votes they got. It should also allow the user to vote for any contestant any time by entering the last name of the contestant."So far this is the only code that I have... not sure why nothing is working.
Public Class Form1
Dim count As Integer = 0
Dim namearray(0) As Contestant[code]....
Write a program that asks a quiz show contestant to select one of the numbers 1,2, or 3 and then calls a Sub procedure that asks the question having that number and requests the answer. The Sub procedure should then call another Sub procedure to tell the contestant if the answer is correct. Use the following questions:1. Who was the only living artist to have his work displayed in the Grand Gallery of the Louvre?2. Who said, "Computers are useless. They can only give you answers."?3. By what name is Pablo Blasio better known?This is what I have so far (with errors):

I am building an application that needs to store different time of day values in dateTime fields of an Access database.I am trying to enter the time value's via a DataGridView using TextBoxColomn s.The coloms are formatted with the defaultCellStyle property to show only the time part of the datetime.After i save the entered data and look in the database itself, i see not only the time, but also the (current) date in the datetimefields. This raises a problem when i want to compare the timevalues later on in the functionality of the program i am building.(Of course it is simple to seperate the date and time part in coding of the program, but it would be more elegant (i think) if i could just save only the time part in the database (and have the date part of de datetimes left to 0))I have tryed via the CellFormatting and the CellParsing events, but no luck.I am new to visual basic and probebly missing out on something.
i want to prevent users from entering numbers and other characters such as (_,"*&^$#).... into my textbox-u know what i mean! I want my textbox to accept only alphabets. I have written a function that is able to check the numbers but i don't know how to check whether the text contains those special characters. Here is my code for the numbers. i'm sure, just as i'm able to check the numbers. i'll be able to check for those characters.
Public Function ValidateText(ByVal GetString As String) As Boolean Dim Count As Integer = GetString.Length Dim i As Integer
I am using a database (access) were i am not using a primary key field. I would like to prevent the user from entering records , if certain fields allready exsists.

I have a program that allows a user to select a program to run at a certain time for a specific amount of time all choosen by the user. Everything works with the exception of if my program has launched the other program, my program become non-responsive. Meaning I am not able to look at that window again. Not that one really needs too, because when time is up my program closes the program it opened, then closes itself. I just want to be able to see my program when the other program is running. how to do this and perhaps drop me some links, that would be wonderful. This is what I have coded, but like I stated there are no code errors.
i am developing a voting software, but i cant able to find the code for increment the no:of vote in the database when an user click on the button.I used sql server 2005 as my back end..
Is there a way to prevent a user from entering data into a ComboBox, rather then selecting, or can anyone suggest a routine to catch and prevent entries so the user can be made aware the they are not acceptable?
I have created an application which asks the user to enter password to login.Now how can i inform the user(if his caps button is on) that his caps button is on while he is entering his password?
I have an ASP.NET application with a SQL Server back end. I am storing all my dates in UTC format and doing the appropriate conversions to the local time zone of the browser viewing it. One of the pages asks for a start date and end date (no times).
I am taking the start date and setting the time to 00:00:00 hours (midnight) and I'm taking the End time and adding a time of 23:59:59, so that the date range covers the whole day. Now what I'm trying to do is do a SQL query to do a search for records in this date range. The problem is, the data in SQL is in UTC time and the user is typing their dates and times in their local date and times. My quickest solution was to convert the date and time to UTC, then search the records. However, by doing this, I am to believe ASP.NET converts the given time and date to UTC based on the server time zone. How can I convert a date and time to UTC time based on the time zone of the user?
I have a text box where i am entering numbers of double datatype andon the Keytdown event of the textbox some checks take pace and in certain circumstances I want to be able to stop the user from entering other information until they enter the right information in the textbox (where it says right here) . now when I say exit sub the textbox somehow loses focus . but this is not how I want it to be I want the textbox to remain with the focus so the user can change the information . How can i go about this. And the other thing is why is my txtDestPayRate1.Focus() just befor the exit sub not working?

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?
writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.
I thought I postet this yesterday but I can't find my thread so if this is a duplicate please point me at the original one. Background: I need to create a user account and Modify it's registry before the user logs on the first time. Creating the account is done by using the Winnt provider (works great). To create the profile I'm trying to use Process.start to launch a process as the newly created user. With the use of loaduserprofile property the users profile gets created and i can do my regwrites without problem.
On the main form of my application, I have a Rich Text Box which is where the user will be entering information. The text is black. then, i have a button which calls the dialogue "Notes" A dialogue appears, with a rich text box. the user should then be able to enter text into the box, click "OK", and the text entered into the Notes dialogue be inserted to the rich text box on the main form -- with the font colour "Red". The rest of the text in the main rich text box on the main form should remain black.
I have a form where the user chooses a facility and then the list of patients for that facility are displayed in a data grid view. When I click to add a resident, the last name field on the data grid view is highlighted in blue below the last record that already exists.If I try to start typing without clicking in that cell, the facility changes - it looks like the control is still in the facility drop down box. How can I code it so that the user can just start typing in the data without having to physically click in the cell to start entering data?
i want to make the Grid view Button(Time In) invisible until the User press Time Out Button. Once the user press the Time Out Button,Time in Button must be shown
i could use some help with this program i'm making, Script:
Public Class logon
Private Sub logon_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Try Dim client As New Net.WebClient RichTextBox1.Text = client.DownloadString("ftp://null:null@null.com/users.txt")
No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).
I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?
