Like anything else in MCI, you can set device information using a MCI command (string/numeric), and this time it’s the MCI_SET command.

This writing talks about hard links and soft links; two of the nice features of NTFS file system.
You can divide file links into two categories: 1) Normal Links (shortcuts) 2) Symbolic Links
This writing will focus on how you can record sound from an input device and how you can play sound files using MCI (Media Control Interface) in C and C#.
This writing does not involve a discussion or even an introduction to MCI. Instead, it provides technical discussion of what we will need to use to record and to play sound files. If you need an introduction to MCI refer to the MSDN documentation.
We will begin by a discussion to types and functions required to accomplish our tasks. Then we will look on how you can utilize those types and functions in your C or C# application.
Our demonstration examples in this writing will be in C. In the last section we will have a look at .NET and C#. Besides this, there are sample applications written by C and C# attached with the article.
This MSDN article identifies the .NET Framework APIs that provide similar functionality to those of Microsoft Win32 API.
Today, we are talking about how to move a form without its title bar.
You might have noticed that some applications with fancy UIs do not allow the user to move the window from its title bar. Honestly, some hide the overall title bar from the user. An example of these applications is Microsoft Windows Media Player -when in skin mode,- and Microsoft Windows Live Messenger. Both applications allow you to drag their windows using the client area not the title bar.
In this lesson, you will learn how to do this trick to move the form without its title bar.
Previously, we have talked about how to change screen resolution and color system via DirectX. Today, we are talking about how to change all display settings -not the resolution and color system only- via API. We will change screen resolution (bounds,) color system (bit count,) rotation (orientation,) and refresh rate (frequency) via API with C# and the .NET Framework.
This lesson focuses on how to programmatically turn on the screen saver.
In addition to clearing the console screen, this lesson teaches you some about PInvoking, marshaling, and memory management. Also you will learn additional techniques like clearing a specific portion of the screen, and changing the cursor position. Moreover, you will dig into IL and see how System.Console.Clear() method do it. More than that you will learn how to reverse-engineer a .NET assembly and discover the code inside.
In addition, the example shows how to perform I/O operations on console using Win32 API calls, and how to show/hide the console cursor. In addition, it demonstrates how to move a text around the console screen.
Swapping mouse buttons means swapping the two buttons, making the right button acts like the left one and vice versa. This is done -for normal users of course- using the Mouse properties dialog in the control panel. See the next figure.
Lastly but not last, and after a long while, Windows Vista introduced a way to create transacted files or even to write to registry.
While market grows remarkably in the last years, its requirements increase as well. And every day you face a new problem that you must overcome to accommodate market requirements.
Transacted operations are one of the commonly demanded requirements by market.
.NET Framework contains holes that you can’t overcome using the managed code. Then you must dig into the API to overcome this.
Some of the overcomes in the .NET is the way that you can’t show a message box that contains a Help button!
