Creating A VB 2008 Change Calculator As An Assignment?
Sep 24, 2010
I am creating a VB 2008 change calculator as an assignment. The program is to use the amount paid - the amount due to calculate the total.(this is working fine). After that, it is to break that amount down into dollars, quarters, dimes, nickels, and pennies. The problem I am having is that sometimes the quantity of pennies, nickels or dimes will be a negative number. For example $2.99 = 3 Dollars and -1 Pennies.
Option Explicit On
Option Strict Off
Option Infer Off

I have a small installment calculator assignment, I have only used VB6 before but i am required to use .NET (using Visual Basic 2008 Express).
There are four fields:
1. Loan Amount (10,000.00 - 250,000.00)
2. Loan Term (5 -25 years)
3. Loan Interest Rate ( Input to 2 decimial places)
4. Payment Frequency (12, 4, 2, 1)
I need to calculate an Effective Rate as:

Then calculate an Installment Amount:

I have a change calculator program that has two user inputs and 6 outputs. The user inputs how much money is owed, then how much money is received. IT will then display how much change you need to give back. It should also display the different types of currency that are available to give as change. Here is my code so far.

What is the correct way of assigning the selected index's value from a listbox to a variable? The user selects an item in a listbox and then the output changes depending on their selection.
I use:variablename = listbox.text
in the listBox_SelectedIndexChanged event and this works.
When I use the button_click event I use:
variablename = listbox.selectedindex
But this does not work in the listbox_selectedindexchanged event.you let me know if it is okay to use it like I did above or if I will run into problems and why you cannot use the selectedindex method.

Since it's been a while since I have done anything in VB and I wasn't that accomplished anyway, I thought I would VB.net (VB 2008 Express) and fiddle around with it. I am in the process of making a calculator, which so far only adds...the other functions will come. The adding is where I am having difficulty. Here is what I've got:[code...]
I am not adding the right things...I know, but I am running out of ideas...too tired, but can't stop now. Just too close to have one function of the calculator working.

i am going creating a simple function calculator, but I had to first do a design documentation proposal. I now have to update the project proposal with a storyboard or list of menu and screen items to delineate my proposed user screen and menus.aside from the calculator itself there will not be any menus.I also have to list any user data inputs and outputs my application will require and produce, which i assume i can put any numbers that the user inputs into the calculator and their results.

I'm completely new to programming and wondered if you could help me. I've designed a simple calculator that can add numbers together but am now trying to create a subtraction button. This seems more complicated, I've searched various forums but am a little confused and wondered if any of you can help or point me in the right direction. Here is the coding I've done for the Add button (cmdPlus):

I am trying to learn how to use the modulus operator.this excersise is a change calculator and is supposed to calculate the number of dollars , qtrs, dimes, nickels and pennies from the change that is calculated.
in the form if i put a value in for owed = 30.00 and paid 34.25 my dollars returned = 4 and that is correct but the number of qtrs = 0 and should be 1. I am not sure how to correctly use this - any assistance you can provide is great - this is purely educational
Private Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
Dim owed As Decimal
Dim paid As Decimal
Dim change As Decimal

It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.

When I have the following code, I get an "Expression is a value and therefore cannot be the target of an assignment." error as shown:

But when I change the structure to a class, this works fine:
Public Class Form1

Public ID As String

What connection am I missing between the two? I don't understand why the first example doesn't work, but the second does. Everything I know says they should both work just fine.

in my calculator script I'm trying to build I have a putton for pi, named Pi. The text on the button is pi. This is where the problem is. Up until now I've just been adding the value of the button to what I call the DisplayScreen (The textbox that outputs your answers), but Pi is not a number. And I want the value of the button to be Pi, not 3.14 whatever. This is what I have for the Pi

just Addition only at this time each number 0 to 9 have this code[code].....here what he says..Write the code for the equals button. There's only three lines in total, and here's a little help.
You need to use the other variable that was set up at the top of the coding window, total2. The variable total1 will be added to whatever is total2.The first line of code will be this
total2 = total1 + (something missing here)
Your job is to supply the missing code. In other words, replace "(something missing here)"
Remember that total1 contains the first number to be added. And you know where that came from. The only thing left to do is to add the second number.For the second line of code, you need to transfer the total2 variable to the textbox.For the third line of code, all you are doing is resetting the variable total1 to zero. That's because after the equals button has been pressed, we have finished adding up. If you wanted to do some more adding up, that total1 will still hold the value from the last time. If you reset it to zero, you can start adding some new numbers.

I was trying to make a calculator which takes the amont of copies you want to make and it tells you the cost. Then you type in the amount you want to enter and if its less a message box comes up saying "please enter more money". I've had a few problems
1. when i use formatcurrency the program crashes for no apparent reason
2. if i calculate cost without entering any copies then it crashes (ive tried putting a msgbox in but it crashes anyway)
3. if i get the msgbox to come up saying "Please enter more money" i had to remove the formatcorrency tag.

Ok. I just took my final for VB and the last chapter we did was on procedures and functions. Functions was the only thing out of this whole semester that I was just completely lost. I'm trying to work on this cause I'm taking Advanced VB next so I wanna know what I'm doing. So I'm trying another tutorial in the book and I'm really lost. Here is what the it wants you to do.
Retail Price Calculator
Write an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item's wholesale cost is $5 and its retail price is $10, then the markup is 100%)
The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item.
When the user clicks the Get Retail button, the program should do the following:Verify that the values entered by the user for the wholesale cost and the markup percent are numeric and not negative. Call the CalculateRetail function Display the retail cost as returned from the function.
Here's what the calculator looks like and my code so far.
Public Class Form1
Private Sub btnRetail_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRetail.Click

I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test.
The calculator can do one of two things:
1 - given an existing network and CIDR(mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.
2 - given an existing network and CIDR(mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.
