I'm trying too have values inputted through a text box, and then have the program calculate how much the person will earn in their working life.
Dim Name As String
Dim Salary, Total, Raise As Double
Dim Age, Retire, Count As Integer
[code]....
However, whenever i click the button to calculate, it gives me how much he would have earned after 1 year with 1 raise, but i can't see what i'm missing.
I am a beginner at VB.net programming. this score calculator. The application is suppose to total up a sum of numbers added, show the count, and an average of the numbers inputted. I try using an array to store the inputted values. Now I'm have issues with my loop keeping track of the total. Also, how do I clear out the array to start over?

I'm working on a console application in VB .net that checks a number that the user has inputted, and tells you whether the number is prime.
The number that has to be inputted has to be between 1 and 100. I have all the code so far and at the moment it can check whether the number is or isn't within the boundries.
I am in Visual basic 2010 express.The user will input how big the array dimensions will be.
An inputbox will appear asking the user to type each row in the array.
How do use substrings to separate that string in into each box in the array. (probably separated by commas or spaces?)
how am i going to check if the directory that was inputted in the textbox is a correct directory?

I'm making a program for a class, as usual. I need it to grab the smallest number, of the 2 inputted numbers.Well, there is 4 inputted numbers. For instance the user inputs the following:
Price Ounces
20 4
12 4
I divide the numbers, and get 5 and 3.The better buy is going to be item 2, as it is $3 per ounce.But I need the program to grab the smallest number AFTER dividing, and then display that in a label. I need to know how to grab the smallest number. What statement do I use?Odds are, it's something simple and I'm overlooking it.
I have created a program in Visual basic 2010, the program contains many different objects e.g. datagridview, textbox, buttons, graphs etc, which can all be modified by the user. The user can also select a file using 'SaveFileDialog'.
Is there a way to save all the properties associated with each object to this file and later load the program back to exactly the same state it was saved in, after the user has selected saved file using 'LoadFileDialog'? Preferably in binary.
I can do this the hard way in ASC11 format by interrogating objects user editable properties and saving them. I would rather not use this method as it will require a lot of code and any future program changes will require a lot of extra work.

I have to write an application that has the user input data in 3 separate text-boxes and press "OK" to save it. The user can repeat this as many times as they want.I then need the application to show the information inputted in each of the 3 separate arrays. Now I was told this can either be done by using a print page or by having another form show the information. I was told having another form would work best. I guess my question(s) are: is it possible to show the information from all 3 arrays in another form? Also, is there a link to any code that can help me out in listing information from a

Ok, i've been making my own syntax highlighter for my project, and i need to know how to make the colour of the text between these two text values green
[Code]...
I have declared an array of text boxes created dynamically at run time. The textboxes are assigned some values by user. The text boxes are located in a Form so that once the user fills in the info and clicks the "ok" button, these values are passed at the back end and the form dissappears. However the user can bring back the form again by clicking another button.
The problem is that once the form reappears, the information previously provided in the form remains. Even the user clears the text boxes to provide new value, the text boxes at code behind do not receive these values.
I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.
With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

i have 18 text boxes with a number in each. i would like to find the 4 highest amounts within theses text boxes. I was thinking i should just load the values into an array and then maybe sort the array high to low and then just grab the first 4 entries in the array after it is sorted.
View 1 Repliesi am writing a golf score program and i have 18 text boxes. i also have a text box that will calculate the total of all of the 18 other text boxes. what would be the best way to add these text boxes? i have already written code to only except numbers 1 thru 8 for each text box.i started with some code like this:
TextBoxTotal.Text = CInt(TextBoxHole1.Text) + CInt(TextBoxHole2.Text) + CInt(TextBoxHole3.Text)
but if there is no value in one of the text boxes i get an error:Conversion from string "" to type 'Integer' is not valid.so i am guessing i need to check for empty strings and then ignore them
Basically i have 12-16 text boxes, with certain values in them.
i think i need a nested loop one to take first box and go through the rest to compare them and then a second loop withint that to do the actual comparison.
