i'm having a bit of a hard time on setting up the calculations.There are three seating categories at a stadium. For a baseball game, Class A seats cost $15, Class B seats cost $12, and Class C seats cost $9. Create an application that allows the user to enter the number of tickets sold for each class and the total revenue.
View 3 RepliesCreate a program which promps the user to enter an unlimited number of test scores. The program should show the high score and the low score. You should use a loop of your choice within this program. The program should look similar to the one below:
View 3 RepliesCreate an application that allows the user to select or enter into a combo box the number of days a person will work, and calculates the total amount of pay she will receive over that period of time. Salary is one penny the first day, two pennies the second day, four pennies the third say, and continuing to double each day.
The combo box must list the following items: 30, 180, 365, and 1000. Must be the default drop down box. Use a validating event procedure on the combo box.
The program should go through a loop once for each day, doubling the number of pennies with each iteration of the loop. You will need a running totl of the number of pennies that you add to with each iteration. To calculate the total amount of pay, multiply the total number of pennies by .01 and show the result in currency format.

I am a new user to VB and I am having difficulty with one of my assignments. The assignment states that to create an application that allows a user to enter three test scores each for three students. The application should calculate each student's average test score and assign a letter grade. The application should prompt the user for each student's name and three test scores.

I have to create an application that lets a user enter as much grades he wants. The grades are between 0 and 100 and they can't be negative. Whenever the user type -1, the application is done and it shows the average of the grades, the lowest and the highest grades.I absolutly have no idea where to start but i must be using loop/do/while.

View 4 RepliesI 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.

I'm attempting to learn VB in college. My first project is to create a program in Small Basic and then write it in Visual Basic. I'm looking for the equivalent of TextWindow.ReadNumber() from Small Basic in Visual Basic. I want to force the user to input a number not letters. I'm writing this program for the Console. Is this possible? During my testing I entered a word instead of numbers and the program crashed.

View 6 RepliesI am supposed to create a program in my VB.net class to do the following:
1. Prompt the user to enter the beginning number and the ending number.
2. Find the sum of the even numbers between these two values, inclusive.
[Code]...
We are currently using for next statements in the class. I know how to prompt for and utilize the numbers that are input etc. My problem is the EVEN numbers part. I obviously have to determine if the number is even and then use a step value of 2 from there. But not sure how to determine if number is even or odd (guessing to use mod, but totally lost).
I am wounder if anyone might have a web site or no where I can find the information so I understand how to prompt the user to enter the beginning number and the ending number. And then to find the sum of the even number. Now does anyone know what a name convention is ? I have tried to look it up on the forums but cant find nothing on it.
View 9 RepliesCan anyone help me to break down the instructions for this assignment.Create an application that allows the user to type in a 32 bit number using the binary system, and convert that number into the decimal numbering system.For example, the user types 000000000000 0010 (where there are 30 leading 0's, 1 then 0 from left to right), and the output would be 2.The user will type a string that is 32 characters in length.A For loop 'reads' each character using the x.substring(i,1) where i is the current character we are reading and 1 means one character only,and x is the entry the user typed (use a Textbox to get the entry but Inputbox is also ok).When you start at the first character (from the right) then that value is to be * 2 ^ 0 then the second character is to be * 2 ^ 1, then the third character is * 2 ^ 2, hence:( x.substring(i,1) converted to Integer ) * 2 ^ j represents the decimal value of the current number (0 or 1) we are reading.A variable is needed to accumulate all those values.After the loop is done, display the accumulated value.To test this code on a simple version, enter a 4 digit binary number, where 0010 is decimal 2, 0110 is decimal 6, 0111 is 7, and 1000 is 8.
My understanding is the user must enter 32 digits into a textbox. The textbox should place limitations that only allow the digits "0" and "1". This error could be displayed to the user with a messagebox that then asks to reset the value orginally inputted into the textbox. My understanding is I should continue creating the formula of the position of each character where the third character is *2^2, fourth is *2^3, fifth is *2^4 and so on? I don't understand the formula and how it works.
How do I make it that the user must enter a number between 1 and 100? And If they dont they get an OK messagebox stating that they must do.I imagine it'll be something like this:
If TextBox1.Text = "" Then
MessageBox.Show("You must enter a value between 1 and 100", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
End If
But Im not sure whats suppose to go inbetween the speech marks.
If IsNumeric(Hundreds.Text) Then
HundredsTotal.Text = (CDec(Hundreds.Text) * 100).ToString("##,##0.00")
DollarAmtVar = CDec(HundredsTotal.Text)
[CODE]..
The above code is from a small program I have written. This test is done on about 30 textboxes I am using for the user to enter number.
The following is the sub routine that is called.
Sub ShowError()
MessageBox.Show(BoxName & " must be a number.")
End Sub
Here is what I want to do but it won't work.
BoxName.Select()
This is so I can put the focus on the different boxes that might contain an error.
I would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
