Cabinet File (*.CAB) Compression and Extraction

.NET does not offer compression functionality. If you search the internet for libraries which are ready to use, you find, for example, ICSharpCode.SharpZipLib.dll which offers ZIP compression. But this library is awkward to use and buggy, and so is unusable. Although the bugs have been known for years, the author has not fixed them....

A fully working multi-threaded file downloader application. A few months ago, my lovely wife was downloading her lecture notes from her university website, and I noticed that she had to manually click on every file to save it to the hard disk.

Opening binary files is allmost the same, you just use BinaryReder / BinaryWriter to read and write to open File , i.e. stream.However the operations you can perform on this stream is limited by the BinaryReader/Writer range of methods. You can read/write all the generic data types( e.g. int, float, byte, etc.) as well as byte arrays. But what about custom structs!? You can use the Serializable options in .NET bu that works with data types created in .NET. What if you have one binary files with ...

Many developers, like myself, with a sufficiently large collection of files to manage, find it at least time consuming to do it manually. There are many tools that one can use, some of them are free, the others require a fee. They fit different needs. I am going to introduce one of them here, which is extracted from the build system that was developed to realize some of our development requirements of being flexible in an evolving (developing!) environment and expandable. Being tight on time and...

Secure FTP for .NET is a versatile file-transfer component for .NET languages (such as C# or VB.NET). It allows you to transfer files directly from your application using FTPS, an extension of FTP which is fast becoming a standard for secure FTP. FTPS enhances the standard FTP protocol by utilizing the well known and widely used TLS and SSL protocol. TLS 1.0 and its predecessor SSL 3.0 provide strong authentication, integrity and confidentiality on both the control and data channels....

Ever wondered how to access the information in an AVI file or wanted to extract information directly from a WAV file? Most people refer external COM objects (like AVIFIL32.DLL) to access the information (see A Simple C# Wrapper for the AviFile Library). The RIFF Parser allows you to access the resource information stored in the files directly by C#.RIFF is the Resource Interchange File Format. This is a general purpose format for exchanging multimedia data types that was defined by Microsoft and...

Often there is a need to convert a file from one format to another. Most of the tools out there seem to cost some money. Not a lot of money, but they aren’t free. Anyway, several file types that you may want to convert to can be done through Microsoft Word. Here is an example of using C# to access Word Automation object to read in a file type and then write out a different file type.

Okay lets see how we can write XML files. Writing and Reading Xml files are most important because sometimes they can also be used as a database. Lets see how we can write and read xml files. Typically, you use an XmlTextWriter if you need to write XML as raw data without the overhead of a DOM.

This article talks about how to set a watch on a file or directory, and take custom actions when that file is modified. These tasks can be accomplished by using the .NET class FileSystemWatcher. You can watch for changes in files and subdirectories of the specified directory. The component can watch files on a local computer, a network drive, or a remote computer. Let's go a little deeper into the class and find out more about it, by taking a look at its methods and properties. The first thing ...

Some time ago, I was sent to work with an old mainframe system. There I became familiar with a source repository where a single file on the system contains several files from the source code. Although this seems very familiar to many people (through TAR or ZIP files), I wanted the ability to work with the files within without copying them to a temporary location. This article is the result of this quest....

If you have ever developed a Windows Forms application that sends files (possibly large) to a web server with a HTTP web service, you will probably already know how poorly the .NET framework handles this task. Web services were designed to send messages, but then people started using them to send arrays of bytes, i.e., from a file. The problem here is that IIS has a request time out, and a maximum request size, which is a problem for large files, even if the developer can control these factors. ...

We often do repetitive and tedious work like coping , deleting zipping files and directories. How we do that? Well, typically manually and when the number of steps is, say greater than 5 , we write a batch file. Easy? Not entirely. This kind of work requires ultimate attention and concentration. If we misspell the file name, possibly the wrong file or directory may be deleted or renamed etc. What about zipping the files or directories from batch?

This helps in searching u'r hard disk for files of the desired extention. I have used System.IO namespace from the .Net framework. So now gone are the days of importing the API's functions in VB or using the fileSystemObject(and adding one more activex component with u'r builds!!!!!) for searching for doing file operations.The System.IO namespace gives us very effective classes for file specific operations.
