In one of my projects we are using PDF templates for the generating the PDF files. Like we create a template first with the textboxes on it and later we can use the template with filling the dynamic data and saving the resulting file. The issue was with the dynamic data not fitting in to the textboxes when the data from database is in Capital Letters. As we were not using the mono spaced fonts like courier. Mono spaced font takes equal number of points while printing on screen or paper say 8X12 ...

Recently I had to build a private online photo album application. I planned to provide the users the option to upload images as a ZIP file. I needed this option to be implemented in ASP.NET 1.1, as my hosting service provider didn't have .NET 2.0 support. Online search lead me to a blog with this wonderful idea of using the ZIP option in J# and it really attracted me. I did want to try it out and the results were pretty cool. Even though this sample application has been written in .NET 1.0, .NET...

Most guest accounts on file sharing sites have a 100 – 300 MB limit on the file sizes that can be uploaded. I usually use the WinZip splitting option to compress my files to be uploaded. At times, there can be problems uploading to the file sharing site. If the files you have uploaded were created using the split option, this means that the downloader would require all the parts to be downloaded before he/she can unzip the file. I wanted my shared image files to be available for viewing as soon ...

This article is focused on understanding the Directory class of System.IO namespace. The Directory class exposes routines for manipulating directories & subdirectories. It contains all kinds of routines like creating, moving, and enumerating through directories and subdirectories. In most of the application developments we require some file accesses or directory accesses normally we use some low-level system API like Directory-Control Routines in C (eg. _mkdir, _chdir, _rmdir) or Platform SDK fu...

All worked well, until I tested on Vista and Windows 7 machines. When trying to browse the "Users" folder, I kept getting access denied errors and no lists returned. The problem is that Directory.GetFiles and Directory.GetDirectories will fail on the first sign of an access denied issue. On Vista and Windows 7, most of the directories under the Users...

Many years ago, when I start learning how to develop software, zippware is one of my first products I developed, I developed my first prototype using a demo of DelZip.

I found that developing such product is a good way to learn how to program window programs. To build the most basic zippware, you have to learn how to do many things using the existing framework, like User Interface, IO handling, Shell, Win32 API. Once you completed the basics, you can apply most new features that you jus...

Windows application generate a thread called main thread when started, in the previous cyoa1 and cyoa2 demo, both UI and Archive operations is run in the main thread. As a thread can only run one execution sequence at a time, if the main thread is occupied by the archive operations (which usually takes a long time), it will be unable to handle the UI work, this will make the screen not updating (and a [Not responding] appear in caption bar)...

It consists of just a single source file of about 200 lines of code, and is thus easily incorporated into your application. This way, you don't have to worry about third-party library dependencies and related deployment issues; simply compile the s...

Many of today's applications require the capability of extracting certain files from a ZIP archive, either onto the hard disk or into memory. A lot of useful zip libraries for .NET applications abound on the Web (SharpZipLib for .NET Framework is a very known one), but I wanted to use the Info-ZIP library as it was always my favorite library for C++ projects. Info-ZIP is an Open Source version of Phil Katz's "deflate" and "inflate" routines used in his popular file compression program, PKZIP. In...

The Common Language Runtime Object Model provides two special methods, the instance constructor and the class constructor. This class constructor method is also known as type constructor or type initializer.

Instance constructor is executed when a new instance of type is created and the class constructor is executed after the type is loaded and before any one of the type members is accessed. We have a perfect setup for field initialization since the class constructors are static and can d...

The following is an example of how easy it is to accomplish the tast of listing files in a given directory on your web server. The snippet of code simply accesses a directory and pulls all the files into a collection that we then iterate through.

.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....

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 ...
