I'm trying to cast the pointer to the buffer to a structure pointer. How do I properly cast this My knowledge of grammer is limited to using C a decade ago. Hopefully this is a very simple problem... though one for which I could not find a posted answer. Thanks in advan

On the other hand, if the same code is written in C#, the exception is caught in the catch block. 2) To futher add to it, VC++ 6.0 is able to catch the same exception which VC++ 2005 cannot, although in the catch
