This member has not yet provided a Biography. Assume it's interesting and varied, and probably something to do with programming.
I have been programming for the past 5 years or so. I started out with C for about 1 year, then took a break and ended up doing Access and VB for a short while. It was then followed by more C, a bit of Java and database development in Oracle and SQL Server and web development in ASP, until I arrived in the C++ and MS windows world. I have been working with MFC for the past 2-3 years and have some COM and Win32 API experience as well. I have recently begun the journey of .NET as well, trying to keep up with the latest hype.
