Learn how to use code tags, without code tags, your code is pretty much unreadable.

If you expect to be helped, shouldn't you ask a question?

[odonal01]

my question is: How do I get this to work?

[odonal01]

plus, you would think that since this a C++ forum, that it would be in C++??

Yes, you would think so? What's your point?
