Funny thing happens when you work in a managed language like .Net or Java for too long. You tend to expect that the language will catch any invalid casts and prevent you from compiling the code. Guess I need to spend more time doing C coding to get back in to it. Thank you, this is most helpful, and i will heed your advice about the cast. Cheers!
