Dear Colleague:

I am not sure whether or not you found the problem yet.

I would like to say that the code in chapter 16 works fine, the main problem to us that are starting programming is that we make a lot of typing error. So I recommend you to check carefuly the code you typed in.

I got many error messages like the ones you are presenting here and I solved every one by checking and fixing the code I typed in according to the book text.

I hope this may help you to fix your problem.

Alex.

andarius40,
I am having the same errors. Iam trying a couple of solutions, will let you know if they work.

Hello I have the same problem in chapetr 15.
Please let me know if someone come accross something.

Hello All
Problem fixed:


Edit Element.h file as follows......

#pragma once
#include "afxtempl.h"

Add
#include "afxtempl.h"

It's easy to mistake afxtempl.h and afxtem1.h (the second having a one (1.h) and the first having an L (l.h)). I made the mistake but caught it quickly. I wish I could say the same about the first time I tried setting up a linux box with a modem! It took me days to realize that ethl vs eth1 was my problem. l and 1 are dangerous.
