check digit

summer tasks

A check digit is a form of redundancy check used for error detection on identification numbers, such as bank account numbers, which are used in an application where they will at least sometimes be input manually. It is analogous to a binary parity bit used to check for errors in computer-generated data. It consists of one or more digits (or letters) computed by an algorithm from the other digits (or letters) in the sequence input.[1]

1. Microsoft Visual Basic 6.0

First released in 1991, Microsoft Visual Basic was a programming environment where one could build an application by visually creating the user interface first, and then adding code. In contrast, even the smallest Visual Basic basic programs could take reams of program code to write in C or C++. Visual Basic was extremely popular for business application programming. The language itself was an interpreted BASIC dialect, however speed was maintained through the use of reusable compiled libraries (DLLs and VBX controls). These however, limited application development to Microsoft Windows.
Visual Basic easily interfaced with many database products (most notably Microsoft Access) and reporting tools (most notably Crystal Reports)
Visual Basic 3 was the most popular version under 16-bit Windows 3.1, while Visual Basic 6 was the most popular for 32-bit Windows 95/NT and later. After version 6, Visual Basic was replaced by Visual Basic .NET, an incompatible successor.

8. Visual Basic 6 Tutorial

Visual Basic, a third-generation programming language, renowned for its user-friendly interface, was first unveiled by Microsoft in 1991, reaching its pinnacle with VB 6.0 before the advent of VB.NET. This language is an excellent entry point for beginners, offering a seamless experience in crafting GUI window applications. Visual Basic 6 Tutorial features forty straightforward lessons and a plethora of sample codes , paving the way for effortless mastery of VB programming. Furthermore, Visual Basic 6 serves as the foundational language for coding VBA, the programming language that allows user to develop macros for Microsoft Office apps such as MS Excel, MS Words, MS Powerpoint and more. Therefore, you might want to check out our Excel VBA macro programming Tutorial.

1. Introduction to Native DLLs - Part 1: Boilerplate

In this article, I explain how to create win32 style DLLs and what the various significant intricacies are.

2. Introduction to Native DLLs - Part 2: Exporting Functions

This article is the second part in my DLL series, and shows the techniques and considerations involved in exporting functions from a native DLL.

3. Dependency Walker 2.2

Dependency Walker is a free utility that scans any 32-bit or 64-bit Windows module (exe, dll, ocx, sys, etc.) and builds a hierarchical tree diagram of all dependent modules. For each module found, it lists all the functions that are exported by that module, and which of those functions are actually being called by other modules. Another view displays the minimum set of required files, along with detailed information about each file including a full path to the file, base address, version numbers, machine type, debug information, and more.

Ways to enforce an interface contract on static methods, similar to what you would expect from static virtual methods if they'd exist in C++

5. Using Win32 Transactions

Ever since Windows Vista, the Win32 subsystem has support for using transactions with file and registry operations (among others). Using transactions, those operations can be tied together and either committed or rolled back in a single operation. This article demonstrates how to do that in C++.

6. Using the Win32 Cryptographic API to Hash Data

This article describes a way to hash data using the latest Win32 API and C++ The Microsoft Win32 subsytem has had cryptographic support since Windows NT4.0 in the form of APIs that were exported by CryptoAPI. However, CryptoAPI has been deprecated, and was superseded by Cryptography API: Next Generation (CNG) which has been the long term supported cryptography API. Its extensibility and algorithm agnostic interface makes it easy to use at the application level. It also makes it easier for Microsoft to implement new algorithms. In this article, I show how a programmer can wrap that API for the purpose of hashing data.
