Press Calculate The Program Should Display The Change
Sep 8, 2011
It is a cashier change return where the user enter the amount owed and the amount paid and when he/she press calculate the program should display the change due as well as the number of Dollars, Quarters, Dimes, Nickels, and pennies returned to the customer. When I run the program sometimes it gives me the right output and others it gives wrong output and it rounds the output. I just want to let you know that I have the option strict on. I will paste the code below
how to start my programming for my visual basic 2008 drive in movie theater personal project. This project I decided to work on will calculate and display the money made by a drive-in movie theater. I just want to make sure I started it right. This is what I started with:
Module Module1 Sub Main() Dim TypeOfNight As Char
[Code].....
Aw yeah, another thing I wanted to ask is how would I do the input, output, and If statements?
At my school i have to make a program and im almost done with it but everytime if i dont put any inputs on the program and press calculate it crashes. What should i write in the codes not to crash if all the inputs are empty.
I need to develop a program (of course.) I need it so the user has 3 text boxes, and puts a number into each text box. Then, there be a group with 2 radio buttons.1st Radio Button: Least to Greatest 2nd Radio Button: Greatest to Least When the press calculate, it preforms the correct operation, depending on the radio button click.I just need to know how to make it so it will order from least to greatest. I then can do the rest.
a. Level 1 - $10.00 b. Level 2 - $12.00 c. Level 3 - $14.00 d. Level 4 - $16.00 e. Benefit Deduction Rate - 0.10 f. Overtime Factor - 1.5
For ease of program maintenance, all of the above rates and factors must be stored in module level constants. All references to pay rates in the program must refer to the module level constants.
When the Calculate button is clicked:
a. The value in the Hours text box must be validated to insure that it is numeric value greater than zero.
1. If the value is not valid, a message box must appear as shown below and the user must be offered the option to continue processing or quit the program.
2. If the user chooses to continue processing, the focus must be set to the Hours text box.
3. If the user chooses to quit, the program must close immediately.
b. If the value is valid, the program must calculate and display the total pay in the Total Pay label.
1. The pay rate is determined by which Job Grade radio button is checked.
2. For hours less than or equal to 40, the total pay is the hours times the pay rate.
3. For hours greater than 40, the total pay is 40 hours times the pay rate plus the hours in excess of 40 hours times the pay rate times the Overtime Factor.
4. If the Full Time radio button is selected, the total pay must be reduced by the Benefit Deduction Rate.
5. The value displayed in the Total Pay label must be formatted with a dollar sign and with two decimal places.
6. The focus must be set to the Hours text box.
Why i get an error when i try to run this code
Code:
Also the message box, both yes and no close the program.....
[code] Everytime i press the Calculate Button, it crashes on my first calculation part. What im trying to do is to not crash the program eventhough i have no input in it.
I am trying to get a function so when i press the calculate button it somes up with sales totals and sales commissions. this is just a simple project i just cant find the answer.
I am having a requirement in my project where User press '.' in his num pad and he wants the character ',' to be displayed (dats bcoz he is French User).
I tried changing the e.KeyCode but it is a readonly property.
Is there any other way to change the key in key events?
I am trying to make it so that when the enter key is pressed, a process or action is executed, and then the program waits for further prompting - For example the enter key is pressed again.
I have used the following code in visual basic 2008 for a windows form:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Me.Visible = True
[Code]....
Where I want to press enter a number of times and have different text displayed each time. Clearly when I run the sub above, pressing enter makes all the text appear at once. How can I make it so that one sentence or paragraph is displayed at a time?
Private Sub cmdLancer1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLancer1.Click
[code]...
So here's the deal... I click Lancer1 button and it displays a randomly generated value into the Textbox1.Then when I clicked Lancer2 it should make so the that first value of text is still present and add another value besides it...
[code]...
But when I press my Lancer2 button it gives a completely weird result and won't display both values seperately... Instead say lancer1 was value of 1 then when i click lancer2 i might get 2 - 5...
does somebody know the user will be able to press enter within a datagridview cell without moving to the next cell. Also i want that the carriage return symbol, i mean a symbol that represents the new line , to be displayed.
Let me see if I can explain it.... Am basically doing a program that records project time for each worker and how much items(by type) they collect in total (No individual total)[code]...
I am using the following code to change the direction of my snake in a game:
[Code]....
I have set it up so that if the direction is set as east and the left key is pressed not to change the direction to west so the snake doesn't eat itself. This works however if the direction is east and I quickly press down then left the snake doesn't have time to move down and just moves to the left causing the snake to eat itself.
When i test a project i usually press Ctrl+Break to pause the execution to change a value here or there, but unfortunately VB opens a new tab titled "No Source Available" and it become difficult to back to the tab that i was working with specially when there are a lot of opening tabs.
Is there any option to stay on the current tab when pressing Ctrl+Break?

I have coded this not sure how to get it to display correctly to the lblGrade box. I have set it up for. Supposed to take the average of three grades and display the letter grade for the average of the three grades.
Here is the code Public Class frmMain Private Function CalculateGrade _ (ByVal txtTest1 As Decimal, ByVal txtTest2 As Decimal, _ ByVal txtTest3 As Decimal) As String Dim AverageScore As Double [Code] .....
This should calculate and display the total amount due. There are 3 radio buttons, A, B, C. Nonprofit should get a 20% discount from final charges.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load End Sub Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles radA.CheckedChanged [Code] .....
I'm developing a data logging application using VB for the actual logging to a MySQL database. I'm reading a value from a device and then running an insert query every minute. This is great but if the value doesnt change all day then my records are going to all be the same. I'd like to try and calculate the percentage of change on the value and only run the insert query if the percentage of change is greater than, say 5%.
I have an app that I'm using Form2 to display informaitonal messages without having the user to press the OK button. I DIM form2 as a new form as a global and then add a lable to it on the fly and then control it's appearance with a timer. This all works great providing the main form is being displayed however I can't make Form2 show up if the main form is minimized or hidden. I can get around this a bit by keeping the main form maximized but change it's Opacity to zero but once I do that I have no idea how to return the Opacity back to normal when I do want to see the form. Anyone have any ideas on how to make Form2 display if the main from is minimzed or how to control the Opacity of the main form so I can return things to normal? I was thinking that there might be something I could do with hovering over or clicking on the icon in the taskbar but I don't know what that event might be.
I am trying to allow a user to press enter in a text box to trigger a text change of an object... 1. Say u put 2 in a text box called "Number" and 2. When you press enter, 3. Another object named and shaped as a book to change it's text, that u can see on the picture to "write".. 4. Originally the book will have the text "Start" on it
Do I changed the "number text box" enter event? Private Sub xNumberTextBox_Enter(ByVal sender As Object, ByVal e As System.EventArgs) Handles xNumberTextBox.Enter Me.NumbertextBox.AcceptsReturn = True end sub Is what I have so far.....
In my form I have Gross Earnings Calculated. Then that goes to a label. I then click a button to Clear Current Employee. Then I can input another employees info to get that employees Gross Earnings.

on the fps form, it is just a simple form with a label in it.

How do I calculate the difference between two dates to display as a number in days?I have 2 text boxes (txtHStart_Date & txtHEnd_Date) I have used an Ajax Calendar Extender to enter the dates in each of these text boxes.I would like to get the difference between these two dates to show in a seperate text box (txtNoOfDays)
I've seen the timespan function but can seem to get this to work. I'm not to sure how to declare the text boxes as the dates I would the calculation to be made from
Code:
Dim D1 As Date Dim D2 As Date Dim ts As New TimeSpan D1 = txtHStart_Date.Text D2 = txtHEnd_Date.Text ts = D2 - D1
But I know this isn't right. I also don't know how to get it to display in the 3rd TextBox.
