Program - Permit User To Input Customer's First And Last Names And Number Of Days That Car Was Rented
Oct 6, 2009
The local car rental company rents cars for 29.95 per day with unlimited mileage. There is a refueling fee of 12.95; regardless of what the level of fuel is when the car is returned. Write a program that will permit the user to input the customer's first and last names and the number of days that the car was rented. The program should compute the total charge for the car that was rented.
I have to do this:
A. using a standard window
B. Using a WPF window (And I don't even know what that means)
C. Using a console application
How would I code a TryParse to get the input from customer from a textbox named Strands and convert it to a number (this number will always be a whole complete number, cannot be 5.6 or 4 1/2 or whatever) then have that Strand number be muliplied by the selected item in my listbox1. This listbox has an access database bound to it with 2 columns Size and Area, the Size equals the Area and I set the Value to the Area column but set the Size to show up in the list box. and the Strands textbox has to muliply by the Size picked, but by the Area # not the Size #. And the results of that multiplication showing up in another textbox named total.
im currently designing a system that enables the user to input a customer record. the customer record is broken down into 11 fields: customer id, title, forename, surname, house no, town, city, county, postal code, contact number, date of registration. Problems - i need to be able to insert the new record into a file and for them to be organized into surname order (for a binary search to work) at this moment it will only sort by first field (which is unnecessary as the customer id number is generated automatically and is all ready created in order). Also, im having trouble with sorting the array that contains all the variables from the text file.
I have a program for class that requires you to have the user enter the number of days they wish to save for and then the program takes 1 penny and doubles every day for the amount of days the person enters. I was able to get this to work in Raptor but not VB.
'Description: Taking one penny and doubling it over the number of days the user enters.
Dim decPennies As Decimal = 0 Dim intTotaldays As Integer = 0
Create 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.
Public Class Form1
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
I have two combo boxes and one text box that verify subject code, user name and password respectively. I want the user to have only three attempts after which a message is displayed and the form closed.The code below is supposed to allow the user to have only three attempts to log on but it rather gives the user countless number of attempts. What is wrong with it?
Dim frm As New MarksEntryFrm Dim flag As Boolean Dim ctr As Integer = 1
I am trying to draw textboxes when the user enters the amount of textboxes to be drawn on one form and the textboxes get displayed on the another form. I have found these codes online but it works with inbuilt codes I guess. That is, the number is already hard coded in the form.
I am making a program which calculates the cost of (Let's say) Spent Electric Energy for a number of days,defined by the user..I have 2 Date Time Picker and x (The average energy spent in a day) where x must be an integer and it is defined by the user x * (DateTimePicker2.Value - DateTime Picker1.Value) = y (The value to be paid for a number of days)
I have an existing database that I want to add a number to that the user inputs. So lets say that in the database there is 4 carrots, and the user on the addinventoryform inputs 3 carrots and pushes a button. Now I want that number to be added to the database number so in the database there would now be seven carrots. I am using an oledb connection and cannot figure this out.
I'm a little baffled why I get this error. Scenario: Printing - 6 different things to print including "Permit" and "Permit Copies". "Permit" looks like a drivers license including a photo."Permit Copies" is exactly the same except it has a piece of text at the bottom that says "Sheriffs Copy".
The problem is when trying to print "Permit Copies". Very few of them shows the print preview - most just display the FileNotFoundException error. If "Permit" pulls up the photo just fine, why not "Permit Copies?" It should be trying to pull up the same photo as "Permit" - same file path/name. Where is it wrong in my code?
I have a date in the future e.g. 13/10/2008 I need to subtract the current date (today is the 28/09/2010) minus 7 days, so thats 21/09/2010 minus 13/10/2008, which would equal erm, 720 something ? But the current date won't always be 28/09/2010, obviously. I need the code for this. EDIT: When i said future I mean past :)
I was about to create a program about CPU Scheduling (SJF Nonpreemptive), Now, I want to ask the user to input the no. of processes ,then based from the user's input I would display exact no. of text boxes where the user could enter the value for each process then store it in an array. But I don't know how to code the text box., I'm new to VB.net and I'm used to it's 'drag and drop' nature. I just want to know how the code to output this text boxes. and is it possible to have an array of text boxes?
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.
Part of my assignment is to check if input to Group Number and Number of Units are correct input by making error handling exceptions...
I have to check the following: a) group number is neither 501 nor 062 b) number of units are NOT numbers c) number of units is NOT a positive number
So my first question is, am I checking correctly? 2nd question is, How do I make sure my Exceptions will pertain to their correct respective things (a, b, and c.. above)?
I need to code a basic multiplication table in VB. I need a popup input box to ask the user to enter a number, then a label to display the multiplication table for that number from 1 to 9.
I have a procedure at the end of my console application that ask the user to either hit enter to end the program, or type s to perform another search. The issue I'm having is no matter what the user types in the program end. What I would like to happen is if the user types s, then the program starts over and lets the user perform another search. The program is procedural and I need to find a way to start back off at the top of the program which ask the user to type a name to search.
I need to write a program that requests a high number and a low number from the user, then the program searches the array and finds all elements within the two numbers. The program is used to search for past presidents, so if I type 43 for low number and 44 for high number, the program will display:
George Walker Bush Barack Hussein Obama
I think I have an idea of how to search up to a certain point, but not to stop at a certain point....Here is the code that I have for that particular sub procedure:
Quote:
Private Sub btnDisplayRqst_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplayRqst.Click Dim sr As IO.StreamReader = IO.File.OpenText("PRESIDENTS.TXT")
Im working on writing a program for doing standard deviation and as of right now im running into one slight issue with subtracting my mean from the original numbers. I will post most of my code so you can get an over view but i mostly just want help on this one little part for now. Im going to be making a website for school and put some programming stuff on it so i wanted to make just some random programs for it so this is school related but not really homework. It's line 26 and 27 that this is relating to. When i put a stop in my code and look at the result of arrayDifferences it gives me 0.0 when it should be -1. I know i can go this route and say arrayDifferences(1) = arrayDifferences(1) - arrayAvg but seeing as how i want this to be a random number of numbers input by the user i cant do that.
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:
how to do array of textboxes when a user input a number of textbox to be loaded and when the button clicked, the array of textbox that the user enters will appear?
I have a homework assignment due for Rainfall Statistic and I started the program by dimming the month name and integer. I know how to get the program to input the number of rainfall for each month, but I dont know where to go from there. I'm new with this IT class and i'm just confused on how to do Arrays.
I'm tryng to figure out a way how I can stop my code from running while I wait for input from a device.Networked device that sends data to .net app.I now wish to prompt the user to answer a 'Continue' questoion and select either 'Yes' or 'No' on the device. This is transmitted to program over netstream.I want the code to pause though while waiting for an answer as different routines are run dependent on the answer.
I'am creating a program that will input a number in a textbox for example 5 and display 5 textboxes in form...I have no idea how to do this but here is the code i've done..
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 am trying to write a program that allows user input information and plot a bifurcation diagram that looks like this:I haven't program in 2 years:sick: so I am all rusty and such. Here is what I have got so far and more information about what I am doing.
Bifurcation: f(x) = kx(1-x) and k = xL + i * (xR-xL) / 500
when i runs from 0 to 500, it plots (i, f(seed)), (i, f(f(seed)), .... up to the boundary number.Here is what I have got so far. Everything seems normal, however, I am really confused when it comes to plotting.
im using a datagridview, and it is connected to ms access. every time i have an input same in the column where primary key is I already got an error. can you guys how to show a messagebox if the Customer Contact number is already in use? here is my code.
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 have a program written in VB 2010 express under windows xp which does some heavy number crunching combined with serial communication. When it "gets too busy" it does not update the screen anymore (done simply with Textbox.text = "any text") and it does not respond to user input in any text box. Not even to a click on any text box. Is there a way I can get the program to do screen update and respond to user input while it is busy?
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.
