Sessions are very important when developing HTTP based systems; however using sessions with certain types of clients in .net can be tricky, I prefer to keep everything simple and under my control, so during the development of some project that uses an old Windows Mobile 6.5 client; I wrote an implementation of a simple session, it supports database sessions only for now.
My design consists of 3 classes and one interface
Storing plain passwords in a database can be very dangerous, any person that can access the database can have all the passwords of the system users, to prevent this; a password must be hashed and the hash should be stored instead of the plain password, when a user logs in, the system hashes the entered password using the same algorithm that was used when storing the password, then it compares the tow hashes if they match; then the user is authenticated.
Hello all;
Having spent more than a year in learning and developing Silverlight applications, had a good look at Flex development, It is sad that I think they are both dead, while it is sad to know that I have wasted a lot of time learning technologies that are probably going to fade within 2 years; it is great that we finally can develop using a technology that is to stay for long terms, yes it is HTML 5.
I have tried some coding in HTML, I used Java Script extensively, which made me change my opinion of this language, it is so great, the new web is literally a revolution, it is really now possible to develop reach solutions using bare HTML, CSS and JS.
I advice you all to make this move, I think it is the future.
Hello all;
I’ve published my new project ArcGIS Silverlight controls on codeplex, have a look on it

Preface
Copying data between workspaces is a day-to-day piece of work for ArcGIS users, and so for developers.
In this article I’m going to show you how to use ArcObjects to copy data between different workspaces.
Actually there are many approaches for doing so in ArcGIS, each of them has some limitation in its functionality, after doing some research on the subject I found that you could transfer data between workspaces in one of these ways:
I was trying to connect to oracle from ArcObjects using the Oracle Provider for OLEDB, after some investigation on the subject; I found the correct method.
Hello All;
While I was developing a set of Silverlight custom controls, I faced a scenario where the PropertyChangedCallback of a dependency property is never called.
In this post; I’ll show you how I resolved the problem.
Hello all;
Finally I’ve decided to host my own technical blog, this blog will hopefully contain my ideas about programming, I focus mainly on C# .net, Silverlight, WCF and ArcGIS development.
