VS 2010 Library System For Thesis Defense?
Feb 16, 2012
I having problems with my program named Library System.As you can see below, I have a form named Books3.vb (Borrow/Return Form)For example, I am the Librarian and you are my student. You borrowed a book that costs a regular fee of 350 (money) from my library now as of 2:05 pm, 2/16/2012 and I assigned you a deadline to return it before 4 days at the same time 2:05 pm, 2/20/2012 and pay the regular fee. If you failed to return it on my assigned time, you will be charged a penalty fee. A penalty fee will be computed starting at the end of the assigned deadline and time 2:05 pm, 2/20/2012 and that will be 1 (one) per hour. For example, you returned it on 2/25/2012, you will pay the regular fee of 350 + a penalty fine of 120 (24hrs * 5days). I just wanted to code it on my program in which will make the computation automated.

I have read syedwaqasali95's thread but found it rater confusing so thought I would post my query separately I am trying to build a library system for a local blind person's charity using Visual Basic. Their current system of recording is an Excell Spreadsheet that was created for them by someone else. What they have asked for is something more User Friendly.I thought about using Access first, but I wanted to hide the Data where it couldn't be modified by accident, and I wanted to make it as user friendly as possible so I opted for a VB WindowsFormApplication that will have a simple user interface albeit having to get more complicated under the hood.The library has two types of items that they lend, Audio Books, and Music CD's. Also there will need to be a record of the members creating three tables for my database.I should state that the library has a laidback lending approach whereby it is less worried about how long you borrow a book or CD, rather it just wants to keep a record of the location of said items.
I need help/pointing in the right direction with the following things 1) I want to prevent any ability to directly edit the datagridview data instead I want the user to highlight the entry in the datagridview, and then click an edit button which will open a form containing the record to be edited.
2) I want to be able to call information from the borrowers database, and to be able to apply it to the books data, so that the user can see who has what book at any given time.
e.g. the user highlights a record in datagridview and clicks the "Lend" button, this pops out a form allowing the user to search/choose from the list of members, once a member has been selected the save button (or confirm lend) would add the member info to the book table and close the form
3) I have a large amount of data (1500 records) in the original excel document, I would like to import these (once the database is ready to be compiled) so that they don't have to be re-input.

What the Win32 API is? I have looked around but no where really outlines what it is. Is it basically a set of procedures, outlined by Microsoft for programmers in order to get services from the operating system? In essence is it the equivalent to making system calls abd and library calls in UNIX? And yes I now Windows makes library calls too.

I'm creating a dll (class library project) file for an OCX. I have an OCX (not Active X, just normal ocx and no need to put on form in order to use it.) which I normally call it from normal windows project's code behind. However, in order to use this OCX, I need to install one software and register with the correct license key.

I just converted a project from 2008 to 2010. I didn't encounter any errors in the conversion.I tried to add HTML Imports System.Threading.Tasks. This gives the "...doesn't contain any public member..." warning and naturally, the .Tasks library is not recognized. Is there any trick to the conversion, setting in the properties, etc. that I need to deal with?Note that I have a "from scratch" project that accesses the System.Threading.Tasks class with no problem. Both projects are contained in the same Projects folder as in:

I need to find out if particular library exists on the users PC. Specifically, d3dx9_41.dll.Typically, this file is in the System32 folder and I've confirmed that its actually there on my dev machine.So I thought I could just use the Exists method of the File class. But, it always returns false. I even tried using the LoadLibrary API, but it always retur

I am trying to create a Library for like code that we use in more than one application. One call involves an array where I need to create a pointer to the array for what I need.
Is there a way to pass a value ByRef, have it increment, and return the value back to the original call?

All of the sudden, I'm no longer able to build a Solution without getting an error in VS 2010. A minute ago I was able to build, and now I can't.
The error is:

I've checked and the .dll is there. I've re-booted and grabbed the latest version from Team Foundation Server.

I was wondering is it possible to put forms into a class library project and if so could I use those forms as an mdi child from my main forms app?A bit behind what I am trying to do:I am creating a game which is essentially going to have its own 'operating system' As the user progresses in the game they can 'install' new software into their operating system.I have my 'Desktop' that is an MDI Parent and what I want the users to be able to do it when they have purchased a new bit of software (also in game) the game will connect to my central server download a dll and place it in a directory, that is essentially installing the new bit of software and the game will then pick up that dll and add a new button the Programs list and when the user clicks on that software in the Programs list it will launch the form in the Class Library as an MDI Child of the 'desktop

I've created a class library and it's shared by several projects I'm working on.
I added a reference to the DLL - but it appears to have copied it locally - and that's causing problems when I modify the class library. Seems I have to drop the reference and re-add it.
I'm seeing info on the web about adding a PROJECT REFERENCE but can't seem to get that to work.
What is the best method of sharing a class library with several other projects.
Actually - should all my projects be in one SOLUTION? Is that preferred.
It will be 5 projects all working with the same class library...

I'm attempting to create a little library to encrypt and decrypt Files with AES. There are loads of examples of how to do this on the internet so coding is not a problem. There are however a few questions regarding cryptography and AES in general.
#1 Does the IV need to be kept a secret like the key ?
#2 Can I just hash a string with SHA512 to make a key for AES ? or do I need to use PasswordDeriveBytes ?
#3 In the case of me using PasswordDeriveBytes Do I need to keep the salt a secret ?(or do I need to keep it at all)
#4 Can I generate the IV from the same password that the Key is derived from ?(if so How ?)
