Installer build into Windows

IExpress is an easy to use, free of charge, build in to Windows setup system. It consist of an easy wizard, which is also a big help to all new software developers. In order to call the program, type iexpress.exe in Run.

This is the first screen of the installer. You can either choose an existing SED file, which is basically a plaint text, or you can create a new SED file with the easy wizard.

Later on, you will be able to chose from different kinds of setups.Ether you create a setup project with an installation command, extract files only, or a CAB file that might be used by other applications.

Eventually, you will be able to specify what to display on the target machine, which files that are to be extracted, a licence agreement, dialog boxes, and more.

An advantage with IExpress is certainly the ability to use it right away – it is already installed in Windows. It is also easy-to-use and it outputs an EXE file. The output executable is also easy to follow, easy to install. Finally, it is free of charge!

A collapse-able menu

This tutorial will show you how to create a menu that can be opened and collapsed. First of all, you need to include a certain script that will do the entire thing.

Basically, it checks whether the object is collapsed or opened, and then does the oppsite; it collapses if it is open, and opens if it is collapsed. You might already now use the code above. By making a for example link (“a”), it will show and hide everytime you press it.

We have a link that executes a command showHide with an argument toShowOrHide, which is, as you might see, the ID of the div. By entering the link, you will either open or collapse the div object. Remember, you might also use other tags/elements that are to be showed or hided. To see this code in work, go to

Get Hash Code with Java Script

Once, I wrote about hash function that I improved. Though, that was C#. In this post I will show you how to get hash code with Java Script. (previous post)

In order to calculate a hash value, you need to define two main variables. First of all, the string to calculate hash from (input), and eventually, the length of the result (hashLength). It is recommended that you set the hashLength to 8 or in some cases 10.

Please take a look at this code in work

Hash code generator

Dear Readers,

The last time I have spent on the development of SKGL API, which is a library for those of you who want to secure, protect your hard-coded .NET application. I meanwhile, I have also spent sometime on a code, (basically half an hour), that produces hash code. It is not the best way of doing it, however, so it would be a pleasure to see another version of this code. Much appreciated!

Secure DotNet Applications with SKGL

SKGL – Serial Key Generating Library is an API that contains a serial key generating algorithm that helps you secure your application. This version is in BETA mode, but can still be used.  (Example is included)

SKGL might be downloaded

HTML Editor online [dev net]

In some of my previous post, I wrote about a HMTL editor available online. There are some new features: (the editor itself) (the list of all available examples)
