(Paul Kimmel) This final installment of the .NET Remoting and Event Handling in VB .NET series takes a closer look at some of the supporting code in the simple chat client and server application that Parts 1 and 2 demonstrated, including the use of the command, observer, singleton, and factory patte

(Ulf T. Mattsson) As databases become networked in more complex multi-tiered applications, their vulnerability to external attack grows. We address scalability as a particularly vital problem and propose alternative solutions for data encryption as an enterprise IT infrastructure component. In

(Huw Collingbourne) In the past, different programming languages tended to do things in their own way. Programmers using C++ would, in all probability, make use of the types and routines provided by the Microsoft Foundation Classes (MFC) libraries; Visual Basic had its own built-in types and routine
