Building A Program That Calculates The Number Of Books By Points?
Oct 16, 2011
I am building a program that calculates the number of books by points.Ex: 1-3 books read are worth 10 points, 4-6 are worth 15 and > 6 are worth 20. The issue I'm having is getting it to calculate the the first 3 books, the 2nd 3 books and then the > 6.Ex: User inputs 8 books read. It should display 115 in the label.
1. I'm using an If statement (should I be)
2. Could I use a decimal for the > 6?
Ex: intTotalNumberOfBooks = (intTotalNumberOfBooks * intFirst3Books) *#D
I know this is something simple and it's out of VB 101, but it is my very first programming class and my professor uses a copy paste method during class.

Library Title Table
Field1: Category
Field2: Title
Field3: Author
Field4: Publisher
Using the Data Adapter ConfigurationWizard Ive created
OleDBDataAdapter1

OleDBDataAdapter2
And from the Library Title table Ive created Dataset2 attached to Listbox2.
Both Datasets fill using the Preview Data function. I then load Variable CategoryString with Listbox1.text,
and I would like to know how to search Dataset2 and retrieve all titles linked to that category and display Title, Author, Publisher in listbox2.

VISUAL BASIC 2008. Program Description: Create a program that calculates the amount of quarters, dimes, nickels, and pennies are needed from an amount of change (entered in pennies). The program should use the largest coins possible (for example, fifty cents should use two quarters, not five dimes, fifty pennies, etc.)
I don't want the code already written out, I need somebody to walk me through making a code. Also, this is my first class dealing with computer programming so all we've learned so far is declaring variables and how to label objects, the simple stuff. I'm at a loss at how to start because a quarter is worth 25 but the program is supposed to show how many quarters once a user enters the amount in cents.

Okay, that's not a big deal... I'll implement FileStreams and read bytes performing operations on them. The problem is that if I do this, the program will hang until the hashes have all been calculated. I want the program to show the hashes calculated so far and a progress bar. I know I need to implement this using threads and interrupts, but how, P.S. Any example code, simply for showing the progress of any operation, and involving a thread,

I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?

Im trying to see if you can make a GUI that can edit the Source code of your progam and then building it as an .exe..Say you have a login program and you wanted to change the password, All you do is go to the "Edit My Account" and go to password and then enter your old password and in the next textbox your new password.Then you would click save and it will ask for a directory and save it as .exe. And when you would start your newly compiled program you can used the program you just entered in.

I currently have a windows services application written in vb.net 2008I want to mass build releases/installers that can carry an unique ID.So that each of my client can download an unique copy of the programMy windows services app must be able to access that unique ID.Heres an live scenario:I have 10000 clients, they can login to my website to download my program.Lets say client #10 downloads my program, the program will be able to read a value somehow that will give "10".The program downloaded by client #500 will be able to read the "500" value.The only ideas i can think of are:- Make the installer read the file name of the installation file, and add a registry key depening on part of the file name.

I have a requirement to construct a Arena simulation model using an entirely separated external VB program, instead of using the build-in VBA programming capabilty. I have some progress on building such program, but not satisfied with the behavior.
Is it possible to create a Model without starting the Arena.exe?If the program halt for any reason (such as termination of debugging) during the model creation steps, the subsequent call to the CreateObject function failed with result like "Cannot create ActiveX/Com objects". This error still occurs even if I manually kill the Arena.exe via the Task Manager. How to avoid this?
-- Current Code --
Try
arenaApp = CType(CreateObject("Arena.Application"), Arena.Application)
arenaModel = arenaApp.Models.Add

building a program at the moment that changes registry entries to turn on and change, and off proxy settings. This small program is going to be dropped on each persons desktop so they can easily turn on the proxy in work, and turn it off when they take their laptop home.
However, the proxy address changes depending on which company I am at. I would like to be able to make a single program, but have a "hidden" setting to change the proxy and store it in the program, and push a copy of the file out across the network to each machine. I tried to make it so the proxy address can be saved as a string in My.Settings, but it would have to be made as a User setting rather than an application setting to give it read-write access.The only other option I can think of is to hard-code the proxy address into the program, which really isn't ideal

I could not figure out the key to installing folders/subfolders/.rtf files during deployment/installation. The key here is to 'add' folders and subfolders to the project in solution explorer, then adding existing item (.text (.rtf files in my case) files) then selecting the .rtf file in solution explorer.go to its properties and under 'Build Action' select 'Content' (very Important!). Then under 'Copy to Output' select 'Copy if newer'!Then in code to access these files you use the following code:
Me.RichTextBoxDisplay.LoadFile(Path.Combine(Application.StartupPath, "KJV BibleOTExodusExodus KJV.rtf"))
Finally after 3 days of research and 2 days at the msdn forum picking peoples minds (smarter than mine) and lots of prayer, I got it!

I am building a program that strips out certain keywords from a much larger file. I am using code that .paul. provided in a different post, but I can't get it to work correctly. Here is the code that I am using: [code] Basically, the first match will appear in textbox2, but no other matches appear after that. I put a breakpoint at the For Each loop and checked out the locals. I am showing 2,502 matches for the variable "match." I just now put another breakpoint in there and I can see that it is stepping, but nothing is recorded.In the archive is a file named debout.txt. This file should be used for the testing.
