Oct 6, 2010
I'm trying to create a form that accepts names (or any strings) as input and stores them in a object. See attached form sample.Form Image:
Operations: ï Initially the NumericUpDown object on the form should be disabled.The user enters a value (string) in the textbox and clicks the Add button or presses the Enter key to activate that button.The application then stores that name in a List object, and displays the last entry in the Label underneath.The NumericUpDown should become enable after the first entry. The user should be able to move between all the values entered using NumericUpDown.

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join 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"}

I have to create an application that prompts the user to enter today's sales for five stores. The program should then display a simple bar graph comparing each store's sales. Create each bar in the bar graph by displaying a row of asterisks (*) in a list box. Each asterisk in a bar represents $100 in sales. I have to make two different versions of this program. One using a "do while ... loop" and the other using a "for ... next loop". Could someone give me a hint on how to do this. I the "do while ... loop" version and I have had some problems, especially with converting the numbers to asterisks.

this is my first vb. and i have assignment and i have been trying for hours but i couldn't do it right I have to create an application that prompts the user to enter today's sales for five stores. Create a loop to prompt for an amount for the first store using an inputbox and do not exit until you have good data. The inputs cannot be negative or greater than 5000, but may contain decimal values. The program should then display a simple bar graph corresponding to the amount of sales using a row of asterisks (*) in a listbox. Each asterisk represents $100 in sales. Display the total of all the stores by looping this process for each store.

You need to design and create a program that accepts input of employee name, employee type, and the number of hours worked each week for two weeks.
You must be able to select an employee type. An employee of type Trainee makes $10 per hour. An employee of type Regular makes $15 per hour. An employee of type Manager makes $20 per hour.
The program should calculate the employee pay for the week. The employee should receive 1 times the regular pay for any hours worked over the prescribed 40 hours in a week. The program should output the following information:
-The employees name without trailing or leading spaces
-Regular hours worked
-Regular pay
-Overtime hours worked
-Overtime pay
-Total pay
The Problem that i am having right now is "Displaying " the overtime hours on my "FORM VIEW" i mean i did the math right its just when i type (lblOverHrs.Text = CDec(CDec(OvrHrsWrkWeek1.Text) + CDec(txtOvrHrsWrkWeek2.Text))
Its says the "OvrHrsWrkWeek1 and 2" are not Declared which are..im not really sure where i went wrong..
Heres my code

I am trying to create an application that will randomly select 14 "stations" (strings) from a list of 33. My thinking is that I have a for/next loop that randomly selects a number between 1,33 which is then inputted into an array (arrnumber) I then want those random numbers to then be used to call the Station name which is saved in the second array, and then for the selected stations to be populated into a listbox (potentially by storing those names selected in a new array?)
Various people have suggested either using a list (of t) instead of arrays, or a Dictionary(?) or perhaps even a database, though I am not all that confident with VB to be able to know where the best place to start with that is. So if anyone can offer any advice, pointers as to how I can link my 2 arrays (I am pretty sure I know how to make the array populate a listbox) I would be very much obliged.
Public Class Form1
Dim Stationid() As String = {"Cardiovascular Examination", "Respiratory Examination", "Abdominal Examination", "Abdominal Examination with Stoma", "Groin and External Genitalia Examination", "Cranial Nerves Examination", "Arm Examination", "Leg Examination", "Parkinson`s Examination", "Cerebellar Examination", "Speech Examination", "Hand Examination", "Elbow Examination", "Shoulder

Trying to create a program that accepts a square array size 4 by 4. Then it should print the totals of the rows and columns. I started with a form and made text boxes and created a print button. I made it so that numbers can be input into the boxes. When hitting the print button, it should print the totals of what was input, however, it isn't doing that. Is there a different way to write the array code so that it will print it? Should i not have text boxes but rather have labels with fixed numbers set in them?

I'm trying to create a program which accepts a letter of the alphabet. For each letter a corresponding word beginning with that letter should be output, e.g., �a� or �A� input would give Alpha as the output, �b� or �B� would give Bravo and so on to �z� or �Z� giving Zulu.So if the user enters: "abc" for example, what should happen is a list on the right of the window appears with the words starting with those letters when the user presses calculate.I don't have any code apart form the basics below.
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged

I'm currently taking a class in VB 2008, with that said I am working with strings and had a quick question. I need to add code to parse the name when the user enters a name and clicks the Parse Name button, this code should work whether the user enters a first, middle, and last name or just a first and last name, before I get decimated by everyone, I am not asking anyone to do my homework because I already have a working solution to this, my question is to see if there is a "cleaner" or more "efficient" way to code this.

I have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.

I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?

I am trying to create a small windows forms application that demonstrates how a user can use pen-based input(ona Lenovo X220 tablet PC) to enter text (rather than typing on a keyboard) I am using Visual Basic in Visual Studio 2010.I think the control I want to add to my Visual Basic Project is the Microsoft InkEdit ControlThe instructions I see on other parts of microsoft websites refer to a .net framework componed called InkEdit. The instructions I found so far is to right-mouse click on the tool box, click 'choose items' and then select the Inkedit Control from the .NET Framework components.

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.
