I am attempting to code a VB project for one of my classes. The assignment is to write a program that take the input of Wholesale cost and markup percent, then calculates retail price. When I finished the code, any input I use results in the retail price showing as $0.00.
Public Class Form1
'Declares a variable to hold the wholesale value
Function wholesaleIsValid() As Boolean
Dim dblTempValue As Double
[code].....
I have about 80% of this app done. All I need to do is convert what the user inputs of the wholesale cost of the item (lblCost and txtCost) and and convert that and the retail price to its markup %(lblMark and txtMark)
View 10 RepliesI 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]

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 have a form as follows "Price changer" The user is allowed to select a product and enter price . So when the change price button is clicked...the price is stored in a array which is later called
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.

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.

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.
Background: I have a program that has implemented the two "classic" taxes for Ontario Canada: 5% GST and 8% PST. At the beginning of July (2010) the province switched to one combined HST tax of 13% for the most part. Effects and changes here but those aren't the main point of this question...
Question: What are best practices and good solutions to accommodate for future changes easily in retail taxes? Tax changes occur often enough. I'm sure there are a many SO users with good experience.
I am trying to build a retail store application that uses a barcode reader. I need to know how to get the barcode data in my application and use it against my items database.

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?

View 6 RepliesThe program is for calculating an amount of fruit. I have a label saying the name of the fruit, a textbox to enter a value of 0-99 and another textbox with ReadOnly which will show the price.
A little picture here:[URL]
As you can see, the Fruit1 Etc... Is only the fruit name.
The Text box wich indicate 1-99 means the number of fruit.
The Textbox with Cash on it, means the total price.
The Calculate button, when I will push it, all the total price from all the fruit will be added together to form a total price which will be indicated in the total price textbox under the Calculate button.
When I will enter the number of fruit, if I enter 99, it give me a price.
When I will enter 60, I want that the 60 are multiplied by (let say) 0,10$
I just like to know how I can do this... Its really bothering e and I don't want to calculate all the things and make 99 line for 1 fruit cause it will be long.
The code I was using was:
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
If TextBox1.Text = "99" Then
TextBox2.text = "10.00$"
Elseif TextBox1.Text = "98" Then
TextBox2.Text = "9,90$"
EndIf
End Sub
Until the the number of the fruit in the code reach 0. So its very long.
I'm reading "Programming with Microsoft Visual Basic 2008". At the end of each chapter there is excersize that I don't have the answers sheet for. Anyway, the first one is:
A procedure needs to store an item's name and price (which may have decimal places). Write the appropriate Dim statements to declare the necessary procedure-level variables.
What I have so far is:
Dim "Candy" as String
So I have an issue with have displayed names in a listbox and trying to write a code to have a hidden price value for it. I want the selected name in the be put into another listbox as a display name and have the price value of it be in a holding value to calculate an equation.I just need help declaring the name with a value in the list box. And How do I list each listbox number so I can retrieve it back as a price value to put in a formula.
