What is an object identifier? Object identifiers are, basically, strings of numbers. They are allocated in a hierarchical manner, so that, for instance, the authority for "1.2.3" is the only one that can say what "1.2.3.4" means. They are used in a variety of protocols. The formal definition of OIDs comes from the ITU-T recommendation X.208 (ASN.1), which is available from the ITU (if you have your checkbook handy). The definition of OID is in chapter 28; the assignment of the "top of the tree" ...

Usually, we insert a link to the external JavaScript library into the ASPX code or just put some JavaScript code between script tags. However, every so often for some reason (accessing it dynamically or some other important case), we need the JavaScript in our code behind (VB.NET or C#). That's where the pain begins. Those who have tried to do it understand me perfectly well. You put your neat piece of JavaScript into your n...

First, in the command prompt, go to the folder in which the project DLL is saved. Then, create a strong name for that DLL by using the command sn -k [strong name.snk]. Then, put that strong name in the [assembly: AssemblyKeyFile("strongnamepath")] line in assemblinfo.cs, and build that project. Again in command prompt, type gacutil /i [assemblyname]. Now, th...

Sometimes, while writing programs, we can get into situations when we need to measure execution times of various tasks. Each programming language provides some mechanism to retrieve the current time from the system. If we read and store the system time at various moments, we can compute time intervals by substracting the values of system time taken at diffent moments. We will see how to read the system time and how to measure time intervals in C#. In C#, the DateTime class is used for storing th...
