I'm trying to make a form that takes user input 3 times, and each time compares it to the correct Answer... which is an array of {"C", "D", "A"}.Each time the user's input matches the correct answer ("strCorrectAnswer()"), then I'll add 1 point to intUserScoreCounter. I'm wondering why this code is returning an error (hilighted in blue)? Can I not compare a String to an Array?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterAnswers.Click
'Handles Enter Answers functionality
Dim strCorrectAnswer() As String = {"C", "D", "A"}
For a class assignment I created an application that takes grades from the user via input box and adds them to an array called grades. Here is some of the code.
vb.net Option Strict On Option Explicit On Option Infer Off
[Code]...
My problem is that the variable x is an integer and the user input from the InputBox is a string so I get the error: "Option Strict On disallows implicit conversion from 'String' to 'Integer'.I've already submitted this assignment with out the first three lines of code (which allows the code to run flawlessly), but I would like to know how to get around the error while still using the Option Strict On parameter. I am aware of the ToString method but I am not sure of how to use it here or even if it will work here. I've tried to use in a few variations but none worked.
I'm making a program like PostIt! Well, i want to make a model form, and copy that form as many times i want.I think it works with something like frmPostit1 = frmModel.clone()
I need some help working out the logic when retrieving specific times from a userform I have created. In my userform, users are required to input a start and a end time in 24 hour time format. I am struggling to work out how best to analyze the selected times in order to multiply them by a set of rates, the rates are quite simple:
DayHours rate (day time is between 07:00 - 22:59)
NightHours rate (night time is between 23:00 - 06:59)
I cannot workout the logic to ascertain how many hours have been selected for which rate in an elegant manner, my best attempts so far are clunky and not quite there.
I am writing a small program here and this i=code is straight out a book and it doesn't seem to work. Its supposed to ensure that the users input is numeric and not contain letters.
Module Module1 Sub Main() Dim user_Input As Single Dim H As Single Do Console.Write("Enter you'r Height in Meters: ") user_Input = Console.ReadLine Loop Until IsNumeric(user_Input) H = CSng(user_Input) Console.WriteLine("You are {0} meters tall", H) End Sub End Module
I am new to VB.Net and programming all together. I am trying to make a program that will take 2 numbers input by the user, Add them together and display the sum. Then take the sum and divide it individually by each number to give you what percent of the sum the numbers are. I'm working on making it a program that will calculate the Hardy-Weinberg equilibrium for my Anthro Class. I'm just doing this for practice for my VB.Net Class. But i will move onto that at a later time. I just want to finish this first.
So.. Here is my code so far. It's not complete yet but this is should be enough to make it function.
I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.
i want to make a program in which the user can input a mathematical function so the program can then work with it. So the user would input something like x^4+x+2 and then an x and the program would calculate f(x). What i don't know is how to let the user input the function.
I'm trying to make a main menu which accepts user input and then checks inputted password for validity against passwords I hardcoded into an array. Firstly, in the for loop, only the first password index is being checked. I'd like the inputted password to be checked against EACH password inside the ValidPasswords() array.
Second, My for loop isn't doing what I want it to do. I'd like to give the user 3 chances to enter a password... If he/she exceeds 3, it tells them they've tried 3 times and exits the form. Right now, it just loops 3 times and exits without giving the user a chance to try again. If I put a return statement in, it just keeps returning and doesn't loop 3 times.
Public Class frmMain Dim ValidPasswords() = {"1234", "2222", "8918", "9911"} 'Dim ValidPWList As New List(Of String)
Is there a way to make one list box dependent on the other based on user input. Here's my situation: A teacher has the ability to enter the name of the student into a listbox via a textbox. The teacher may then select the student from the first student list box and input grades that would go into a grade listbox. If the teacher selects another student from the student list box, the grade listbox would either go empty or show the grades inputed for the other student; all the while retaining all previously recorded grades for other students.
how to code a function that causes a function to pause until the user either changes a radiobutton or hits the reset button or that will restart the function if one of the entered txt values or comboboxes Index have been changed and the uptade button is clicked.

Vb is not my language of choice , but I have to do this for school and I'm not having a very easy time with VB's documentation.I'm just creating a very simple console application that accepts user input: degrees in Celsius, and converts it into Fahrenheit. I want to make sure that if the user just hits enter without entering the degrees in Celsius, then an if else statement will catch and write to enter Celsius again.Here's what I've tried:
I am working on a project using Visual Studio .NET 2003.I am trying to open a second form based on user response to Yes/No Message Box. I have tried two different code variations. The first variation is:
Dim MsgAnswer As Boolean MsgAnswer = True Dim MsgRes As DialogResult Dim CustomerInfo1 As New Form
[code]....
With this code I get an exception error: An unhandled exception of type 'System.NullReferenceException' occurred in OrpheyOnOpen.exe Additional information: Object reference not set to an instance of an object.
I would like to develop a structure to maintain my user's text input somehow on each form to allow user to return to the form and see the prior input for potential editing. My app has four forms which accept user input and form a string for output to printer. In the eventuality that the user notes a mistake in the input after leaving the app, I would like to develop a structure to "save" the user input at the form level and allow for repopulating the text boxes with the prior user input. Make sense? I have no idea how accomplish that functionality. Maybe it's too complex for my purposes. What do the pros think?
how to create a form that allows a user to load an input file? I'm assuming a form like a windows explorer window will be too difficult, or not? If it is then I guess I could just put a textbox on the form and ask the user to input the directory with file name.
i have a access database with two tables, one for customer and one for booking.
I then have a form application i made in VS 2008 which lets a user enter details such as their name phone number ect into text boxes.
All of the information the person enters thoughout the program is shown via labels at the end, all on one form.
Would it be possible to then have a button that when clicked saves all of this information into the access tables into the correct columns, im sure it must be possible i just don't really know where to start.
I would like to create a form there I can enter three values (A,B,C)in textboxes and then submit these parameter to a program that run in a dos promt windows. Parameter A , B , C..Program.exe /A /B /C..It would be great if I can have a progress bar as well.
I am making a windows application that should validate user input before opening up the next form page. I can get the error messages to show, but after correcting the error, they won't disappear and open up the form.
i developed an application which takes input from drop down list and then creates files when we click on that button for specified value in dropdownlist.And if we click on send button it sends to remote database.All the application is working fine.

I have created a form which has two things a list box and a button which is labeled "Input Values"The user should click "Input Values" and a new form will appear. This new form will ask the user to enter 10 values into a textbox and click ok after each value. These values are to be stored in an array and displayed in the listbox on the previous form.I am having trouble getting the values of the user to store into my array and displaying into a list box. I have this so far.

I am trying to figure out how to generate code from user input. In Visual Studio 2008, Visual Basic.My script always begins with:function Init (Quest)Then from here a user would input a quest name, type and zone in a interface using windows forms.[code]I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.Is there anyone that can explain how I would go about doing this. Or maybe some kind of visual studio plugin that will help me out.
How to generate code from user input. In Visual Studio 2008, Visual Basic. My script always begins with:
Code: function Init(Quest) Then from here a user would input a quest name, type and zone in a interface using windows forms. Ex: Code: RegisterQuest(Quest, "Kill Zombies", "Heritage", "Firestorm") end This part a user would enter in his interface what would an NPC say if accepted. [Code] .....
What I need is a few text boxs that a user can input "Kill Zombies" or whatever they like and when they push a generate button it will create a file with a .quest extension. All of the code remains the same except for the quotes that would be the user input from the interface. Basically everything in quotes can be changed by the user in an interface. I have created my own functions for when a user accepts, deny and complete a quest. The user just needs to input what should happen then click a generate button to throw it all together as a .quest file to be saved in his or her quest folder for the server to call on later.
I also have many other functions like: AddQuestRewardFaction --- (Quest, Faction ID, Amount) AddQuestRewardCoin --- (Quest, Copper, Silver, Gold, Plat) AddQuestStepObtainItem --- (Quest, Step ID, Description, Quantity, Percentage, TaskGroupText, Item ID(s)) Etc
I would also like to have these available on the UI but wont generate unless a user checks a box to add them or there is a box already for them but wont step into the code unless the user enters something into the box.

I am making a banking system in Vb.Net but I had a problem with this function. If a user fails to input the pin number for 3 times, it will be block automatically and will need the admins permission in order for that person to activate the account again. I really don't know how to code the blocking of account and asks for admins authorization to unblock the account again. By the way I'm also using MsAccess as my database for my Bank Simulation.
I am doing form validation in VB, I validate the text field data by using txtName_LostFocus function, and on wrong input I used txtName.Focus(). It works well for me. But problem is that as for as, user does not input valid text, my EXIT button also does not works.
