Adding Decimals (Vending Machine Account)

I just started doing a semester of Visual Basic in college(australian), our first assignment is to make a vending machine app but so far we've only been taught basic coding such as making time converters and forms. I've tried to ask the teacher for help and she refuses to help us, she tells us its unfair. None of my friends in my class know where to start and everyone else is cheating of the internet. I just want to know how to start making the application. The vending machine must have 6 products with 10 of each, the user must put in 10c, 20c, 50c, 1 dollar and 2 dollars. Everytime the user buys something it must deduct 1. The must also be an admin function.
View 6 RepliesI am currently creating a vending machine program, designed to simulate a vending machine. However I have come across a rather large error, my stock is 50 at the begging. The person can go though the program and the appropiate amount of stock is taken away from the relavent object, however when I finish and want to go back to the start the last selection is still present.Therefore I have tried setting the variable as 0 when the form opens and when the program starts, but the last selection is still present.Does anyone know of a way to which I can reset this calculation without affecting my stock so I can then repeat my program cycle one or two times each time using the previous stock without reseting back to 50
View 10 RepliesI am making a Vending machine that requires you to logon and then you can purchase things and the purchases are deducted from your balance. The logon information as well as the balance is stored in an access file. I have the logon working well and understand everything except the things dealing with the balance. How can I make it so that when you logon it takes you to the purchase screen and The person you logged on as name and balance are shown on labels. I also don't know how to deal with balance. So when they log on and purchase the amount is detracted from their particular balance.

Using VbScript:: I have a list of several different prices and I'm trying to figure out how to round these 5 decimals adding zeros if necessary.
For example:
I want:
2.84
3.1
4.896
To look like:
2.84000
3.10000
4.89600
Dim y as integer
dim x as double = 125 / 60
y = Convert.ToInt32(x) 'removes decimals
That method works, it removes all the numbers after the decimal.
But, how to check if the double contains a decimal and if it has it, remove all the numbers after it?
I have tested all the possible solutions i can think of, but I always run into a lot of errors

View 6 RepliesI've inherited a lot of custom made software for an office, and, while managing it, I've found it performs differently from machine to machine.I mean, some controls get painted in weird ways in some machines but well in another, or just work differently, like in some machines clicking something selects it, and in the next machine clicking the same thing makes it editable.I suspect, o course, of the myriad of DLL the software loads

View 4 RepliesOk this is what I'm stuck on:I have 2 ListBoxes and 2 Lists, let's call them ListBox1, ListBox2, List1 and List2.List1 needs to be associated with ListBox 1, and List2 with ListBox2 I loop through a bunch of accounts, add them to LixBox1 at run-time.During that loop I add each account number to List1 so now the account number is associated with the ListBox index number which is right.Now when I double click one of the accounts in ListBox1 it is added to ListBox2 (but it still remains in ListBox1), and the same index of List1 added to List 2, now the account in ListBox2 is associated with the account number at the same index in List2 you see where I'm going with this?The issue wtarts here.When I double click an account (let's say the account at the first index) in ListBox2 it should be removed from the list, so now I remove the index from List2 since it's no longer needed, but now you know what's happened right? ListBox2's List indexes have all decremented by 1 because I just removed an item from the beginning of the list, but List2's indexes have stayed the same (at least that's how it appeared when I tested it).
So basically whats the best method for keeping things in reference? I was told about list boxes in another thread of mine, but is it really the best way to go about this, I can't seem to keep everything linked together reliably.
I have a textbox that requires the user to input the value of the Value-Added Tax of that certain area. I tried testing 12.5%. The string is converted to decimal then divided by 100 so 12.5/100 = .125. But when the program writes the value to a file, 0 is writen. not .125
View 23 RepliesIf i wanted to know if a whole number is a multiple of 10 or not I know i can do for e.g
If VarWholeNumber MOD 10 = 1 Then
......
Endif
But if i have a whole number with format "0.00" how can i only check if the last 2 digits after the decimal is a mod of 10 regardless of what the whole number sides value is.
So something like
If VarWholeNumber's ".00" MOD 10 = 1 Then
.......
Endif
How could I could this?

i have three cells in a datagridview third cell gives the result of multiplying first and second cell.When i reload or populate this data from datatable into that datagridview value comes like 40.00. with two decimals. For example
58.00 -------->i need only 58
58.78--------->i need exact 58.78
The only problem is to remove the decimals if they are 0.
I am using two forms and the results from form 1 i want to show on form two.The results are in dB(decibel). I get a long result lile 142.1233344444 dB. I want this result be like this 142.12 dB. I use value _passedText to get value from form 1 and display it on form 2 textbox results.text
passedText = Value
Results.Text = Value
What should i do to round off it in vb.net 2008.
Is this the proper way to bring up an error if the user inputs more than 2 decimals. 'Not decCost = [0-9]*.[0-9]{0,2}

View 2 RepliesI've used .NET for a long time now but I have come across something I haven't had to do before and I'm struggling to work it out. What I need to do is work with binary numbers and convert them to decimals and vice versa but not necessarily using even numbers e.g. I would like to represent a number between 0 and 2047 which can be represented with 11 binary digits. Plus I want to represent a second number between 0 and 500000 which can be represented with 19 binary digits, and a third number, fourth etc. Then I want to string the whole binary results together and split it in to sections of lets say 5 bits each and convert those back to decimal.
