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 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.

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:

The 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 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]

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.

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.

Using the attached code, the goal is to draw a series of 1x1 rectangles to produce an image of a line. The image begins okay at point (0,0) but ends up after 5600 passes through the loop at (1884,5273) instead of at (1965, 5244). To prove the scale factor accurate I also use Drawline to draw the entire line with the same scale factor. Drawline ends up at the correct location (1965,5244).
I've manually checked the calculations with the results as noted. I'm at a total loss to understand what's going on.
' Xc = 1965
' Xp = 0

How to display/calculate matching values to text boxes in (Service Details Group) and transfer/calculate it all to Rich Text Box (TOTAL $)
View 4 RepliesSo I need to get a button to take the number that a user enters into a textbox, calculate the factorial from that number, and display it in another textbox. I can't seem to get this to come out right.
Here's some of the code I've been playing with.
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Function Factorial(ByVal txtFactorial As Decimal) As Decimal
If txtFactorial <= 1 Then
MessageBox.Show("Enter a number greater than 1")
Else
txtAnswer = Factorial(txtfactorial - 1)
End If
End Function
Now I have to just work out the code part. Can a function be under a button? I'm getting an error about that. I'm also getting an error about the txtAnswer=Factorial(txtfactorial-1) part of the 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?
