Calculations Using Quantity And Price - Not Getting Right Value
Jun 3, 2011
I got a program I am working on. It does some calculations using quantity and price in such. Heres the calculation module.
Private Sub calculations()
If AdultsizeRadioButton1.Checked = True Then
adulttotaldecimal = quantityinteger * adultpricedecimal * hoursinteger
ElseIf ChildsizeRadioButton2.Checked = True Then
childtotaldecimal = quantityinteger * childpricedecimal * hoursinteger
[Code] .....
Ok, everything has worked when I display the information.... up until the accumprofitdecimal variable. When i display that value its NOT what it should be. For instance i'm putting in a quanity of 1 and an hour of 1 for an adult then for a child, the extended price comes out properly as $2.15 now the code accumprofitdecimal += extendedpricedecimal SHOULD add the extended price (2.15) to the accumulative total. but when i display the accum profit total it shows a number that makes zero sense... is accumprofitdecimal += extendedpricedecimal not correct code?

I am struggling to write the code for a calculation. The calculation I wish to do is to multiply the quantity of an item by the price. The problem is that the "form" i am creating uses a letter (i.e A, B, C etc) which corresponds to a set value. I do not know how to link the Letter to the corresponding value.
For Example, A= 25, B= 20, C=25
I want to calculate the total of 6 lots of A. I am also using a Combo Box to list the Letters.

I certainly hope I don't aggravate you with what is certainly a very simple code problem. I have never programmed before, but I do have a background in tech support, etc. I have an assignment to do and it's frustrating to wade through the information out there to find exactly what I need and nothing more.The assignment has 3 parts, one of which i've done. We are to do the same function in both javascript and VB. I was able to take a sample we did in class that caluclates a 10% discount and modify it so it calculates the total. Now, I have to modify that into a VB sln file. then write about the differences but that part will be cake.
I am working in Visual Studio 2008 - that program is new to me as well. When I created my login and it asked what VB I'm using, I did not know but under theu of VS, it says VB 2008.hat I attempted to do was to take the instructor's sample discount code and modify it for the new purpose, but an error was generated. This is the sample code I started with:

I started this tutorial on sub procedures and am having trouble trying to get this program to execute properly. The problem lies with the total. I am trying to figure out the math part of it. When I hit F5 I can see this
Item Quantity Price.
Pizza Slices
Fries
Soft Drinks
Total
But I can't get them to add up and display the quantity and price. I tried the ByVal and ByRef code but am not sure if I did it right
Here is the code that I have so far:
Public Class Form1
Private Sub btnCompute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCompute.Click
Dim pizza, fries, drinks, total As Double

I have to create a program where you enter the description, price, and quantity of an item, then click on the Add button. It will then put the description, price, quantity, and total for that line (including tax) in a listbox. The tax is determined by what you put in a text box labeled tax:. When you press Submit Order, it should show a grand total in a text box called Grand Total. It should have a class that is called Items that has a function called GetTotalAmount() that figures out the total including tax. I have started it, but am having a tough time with how to get the subtotals into the text box, then also show the amount including the tax PLUS then do the grand total.
Heres what I have so far:

I am new to vb and I am having so much trouble with this. What I need to do is this: I have a form application for winter sports equipment rental.I have a listbox filled with the equipment for the user to choose from then I have a combobox for the user to select the duration they would like to rent it. The book that I am using has no examples I can refrence and i have had no luck online either. I am posting what I have so far. However, i think I am going in the wrong direction. I have been working on this for so long that I think I have over thought it and made a mess of it. I am thinking that I need to add a new class for rentalRates then use enum of durationType and equipmentType but I am unsure how to move that way. That is using a enum, a 2d array and a parallel array? [code]

So what i am stuck is when the user selects a product from the drop down menu...the user can enter price . But i need to display a error message when the user enters text instead of numbers for prices. I tried try parse method but it displayed the error message but did not transfer the entered price to the array.
My code is as follows

I have to create a form that I enter the price of gas each month over a year. I enter the price in a text box and click the enter button to send the price to a list box immediatley and use an array. I have the following code but I don't think it's working with the array correctly as it will let me enter the information but doesn't stop letting me enter after the 12 prices. I am really having a hard time trying to figure out how to set up this input for an array and make it all work.

I have a project which is 98% complete. Its basically a Shop(till) interface. I have a form that has tabs the first being the main till, second shows a listview with everything in stock and the quantity of items in stock. Im stuck on one part of the program where when the form loads it checks the stock and if any of the items have a quantity less than 5 for example than it displays a message box to the user telling him/her to order new stock, but im not sure exactly how to do that.

I'm working on a project for a client (he wanted it in VB.NET so I dont have a choice) and have hit a wall. I have a Product class, and a List(Of Product) that I'm using to store products in while a new order is being built. The problem I'm running into is updating the Quantity value of a product if it's found in the list (instead of adding the product again).

Currently I have two tables in a Database (Temp, Main), currently I have four fields in Temp(ID, Qty, LastDate, AddRem), and Three in Main, (ID, Qty, LastDate). I have the program set up to enter in all the information minus AddRem into Temp, then my thought was to either tag the item to remove, or add to the Main table. I'm assuming this could be done by import then update, however every avenue I've attempted has been meet with Exception errors.For the add/remove field it is linked to a Combo Box, which brings me to my other question, how would you link a specific field to say hey if it's this option then add, and if's the other remove?

I was wondering if someone could translate this code into a more understandable code. It is suppose to be a function that accepts an item name its cost and its quantity. and adds one more array element to ."items" variable and assigns the given name and cost and quantity.
Public Sub AddItem(ByVal strName As String, ByVal dblCost As Double, ByVal intQuantity As Integer)
Me.items=DirectCast(Utils.CopyArray(DirectCast(Me.items,Array),New Purchase(me.itemsCount + 1)-1){}),Purchase())
End Sub
This is the translation i made but i don't think it is correct.
Public Sub AddItem(ByVal strName As String, ByVal dblPrice As Double, ByVal intQuan As Integer)
Dim items As Purchase() = Me.items
Dim itemCount As Integer = Me.itemsCount
For itemCount = 0 To items.Length - 1
