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.

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 am trying to change the background randomly from a selected list after a certain amount of time. I have the array set-up and I have it picking a random path (ex c:images est.jpg). I found in the registry the background image settings. I tried setting the registry key to the path but it seems like there is more to it than that because it doesn't change it. I also saw where it stored the file and tried changing it but again it doesn't change it. The funny thing is if I go to display properties afterwards it shows the correct image just doesnt set it. If I then click a different image and go back to it then it sets it. How can I make it update the background?
View 5 RepliesI 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

I am having problems with creating this change problem. The idea is that the user puts the amount of money in the textbox and then in separate textboxes shows Dollars, Quarters, Dimes, Nickles and Pennies.
Example:
You Money: 12.54
Dollars: 12
Quarters: 2
Dimes: 0
Nickles: 0
Pennies: 4
Here is the code I have so far:

what is the best way to handle on selection change when the form loads?My problem is, the index change while te form is being loaded, which then in turns tries to run my code.Here is the FormLoad Event, that gets an xml stream from the web, dumps it in a dataset, then bind to datagridview.
Private Sub frmOrders_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Using reader As XmlReader = XmlReader.Create(New StringReader(XMLDoc))

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.
I'm sure I've done this before but I can't for the life of me figure out how to change the EXE output name for my project!

I know that I can launch activate/Use functions in assemblies that I have created, but can I start subs? and If so could I start Sub Main from an Assemble? What I mean is I want to run the created program in memory from a sub main and I dont know how .
My other question is how can I change the type of output project? So from a console app to a Windows Form app? ( I am no longer talking about using the assembly dynamicly this is more about creating the physical exe as what I want it as.
I know that they are the Compiler options command line but is it the same as the ones that Visual studio use when compiling? (The ones you see in the out put window)

View 5 RepliesI have a VS2008 solution looking at data in a sql express table. I've got a Binding Navigator on the form, with all the usual controls. If there are, say 20 records, the BindingNavigatorCountItem shows 20 and the BindingNavigatorPositionItem shows the number between 1 and 20 whichever record I'm looking at, as it should.
I have a field in the table that gives each record a unique number. In a collection of 20 records, this unique number could be 20 different numbers in between 150 and 230, for example, as records have been deleted and added over time, or depending on the filter criteria applied to other fields in the same table.
Is there a way to show this unique field value in the BindingNavigatorPositionItem box, rather than the sequential number in the collection? and be able to type the unique number in that box and have the record jump to that one?

It is a cashier change return where the user enter the amount owed and the amount paid and when he/she press calculate the program should display the change due as well as the number of Dollars, Quarters, Dimes, Nickels, and pennies returned to the customer. When I run the program sometimes it gives me the right output and others it gives wrong output and it rounds the output. I just want to let you know that I have the option strict on. I will paste the code below

I am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?
I am having trouble getting the Student Name entered in the Student Name Form to change the Text titles of the GroupBox's on the Main Form and Schedule Form. I understand the logic of what needs to be done to some extent, but I am having trouble coming up with the correct coding.
