Introduction:

This tutorial is on how to use OOP (Object Oriented Programming) in C#.

What is OOP?

OOP is when you are able to run multiple instances of one class or form at one time without them colliding in to one another. I will give you an example; Let's say that we have a 'person' class, with the variables to hold that person's name and age. Without OOP, we could only have one person.

Introduction:

This tutorial is on how to use the Skype4ComLib Libaries in C# .NET to access our Skype program on our computer.

SKYPE4COMLib:

I am using 4.5 for this tutorial, then you want to create a new Console/Form application in Visual Studio for a C# application. Right click on your application in the 'Solution/Package Explorer', click on 'Add', then 'Reference', select 'COM' from the side tabs, and choose 'SKYPE4COMLib Libary'.

Introduction:

This tutorial is on how to secure your application in C# from Buffer Overflow Attacks.

What's a Buffer Overflow Attack? (BTA)

A buffer overflow attack is when the user purposefully enters too much data in such a way that the program will spill the data across different memory locations which will cause unexpected behaviour such as opening another vulnerability for the attack to exploit. This works through the use of user input.

Introduction:

This tutorial is on how to use Switch statements in C#.

Switch:

A switch statement allows a single variable or static piece of data to be checked for mulitple conditions, essentially like a long 'else if' statement but a lot more compact and with slightly more flexability.

Case:

To use a switch statement there are a few other keywords we need to learn first, one of which is 'case'. Case is a possible value of the variable or value being 'switched', this must be of the same data type as the value being switched and must be followed by a colon. Break

Introduction:

This tutorial is on how to draw text in .NET (C#/Visual Basic).

Labels, Textboxes?

I'm sure if you've not looked in to the 'graphics' (etc) objects in the .NET framework, you're thinking, why don't we just use labels or textboxes with their read-only property enabled. Labels and textboxes both have a surrounding area around the text which are both of different colours (however we could change this to the form background colour to give the effect of the backgrounds being removed), but would we create extra controls (labels, and textboxes) when we don't need to?

Introduction: This tutorial will be on how to use a 'foreach' loop in C# .NET. ForEach: A ForEach loop in C# is used to iterate through a list of elements held within one location. An example of this could be a list of usernames which are allowed to login to the program.

Introduction: This tutorial is on how to create a HTTPWebRequest in C# using a proxy connection. Why Proxies? Proxies are sometimes required in certain web scraping applications due to the sheer amount of data that needs to scraped. Some sites temporarily - or even permanently - block IP addresses which are requesting/receiving large amounts of data in a short time to avoid the website's full bandwidth being used on that single IP, and therefore stopping the site from going offline for all other users as well.
