MemoryMappedCache is a small project can be used to host a proactive loaded cache using a Windows Service. This cache uses Memory Mapped Files internally. Other applications on the same computer can then also use MemoryMappedCache to access information stored in this cache. This is done much quicker than using .NET Remoting. A significant amount of time was spent to ensure that this cache can be accessed from within ASP.NET if the cache is hosted by a Windows Service....

The Windows operating system has never been a better platform for programmers. Hundreds of languages target Windows® either directly through the Win32® API or through the CLR, and more are being built as you read. One of the goals of the CLR was to enable a thousand flowers to bloom in one compatible ecosystem, where languages and APIs seamlessly integrate within the same runtime. It thus far has succeeded fantastically—new languages are popping up everywhere....

XML RPC is a standard for calling functions / passing parameters to these functions / retrieving return values from these functions. The caller program and the called function typically exist on separate machines. If a server is available and it provides some functions then a client anywhere can call these functions via a simple HTTP (or HTTPS) URL. The parameters are sent from the client to the server in a form of XML text. The server then receives the parameters and carries out the actions req...

A delegate can be defined as a type safe function pointer. You use delegates to call the methods of other objects. They are object-oriented function pointers since they allow a function to be invoked indirectly by using a reference to the function. It wraps up the memory address of a function in your code. The system makes use of delegate whenever you create or use an event in code. When an event is called, the framework examines the delegate behind the event and then calls the function that the...

Yes - I know there are all sorts of official tools like bulk copy and data translation services. However, this technique is useful sometimes and is flexible. The idea is simple, create one single SQL script that removes all the data from a database and then restores it all to a pre-recorded state. This boils down to a wh...
