Having a forward declaration for A (that's the 'class A;') shouldn't help in the definition of B - B would need to see the full definition of A to have a member of type A.
Oh well. If you've got it to work...

My thoughts exactly. However, I placed #ifndef _SOCKETS_OBJ_DECLARED_ around the 'class A;', and in the 'B.h' at the end, I added #define _SOCKETS_OBJ_DECLARED_
Then, when I placed an #error "Undeclared" in the #ifndef, it threw the error.. so for some reason, the header is being included but it's not globally declaring the 'class B'. It's really strange, and another programmer said he couldn't explain it.
The best I can do is go through it with a fine toothcomb and hopefully find where it's not declaring properly.

I wonder if you've just got a missing semi-colon or something somewhere - that can cause really bizarre error messages and can be really hard to spot.

I have no idea. I've been rooting through these header files, and as far as I can tell there are no missing semi-colons.
In Visual C++, the actual region inside #ifndef _PACKETS_OBJ_DECLARED_ is completely grayed out, suggesting it should never be called, however it *is* being called, which might be something to do at compilation time.
This has absolutely lost me, lol.

I am currently writing an application using MFC and C++. I am also using Visual Studio 2008. I have concerns that it is leaking memory and/or has array out of bounds issues. I am thinking about buying Purify to verify this and find these bugs. However, its cost is over 800 dollars which is not in my budget.
I am hoping that somebody out there can recommend another tool which is just as good but has a lower price. One such tool is MPatrol but I have never used it and I am wondering who has and what they think of it.
Thanks
Bob

David,

Then you should be able to detect most, if not all, memory leaks. Run the application using F5, and when it shuts down, MFC will report what wasn't freed in one of the output windows.

David,
Thanks for the response. When I do that there are no memory leaks reported MFC or Visual Studio. I am thinking that it might be the case that I am freeing memory not allocated or allocating x bytes and using more than x bytes. Not sure.

Bob,
Have you tried DEBUG_NEW[^]?

Hi
I have a third party process that modifies the selected text in the currently focussed application window when a hotkey is pressed (e.g. you select text in your text editor, the process wakes up and shows the modified text in a pop-up window and pastes it to the clipboard). I want to trigger this process from an MFC application. I would have a text window in a dialog box to which I would write text programmatically, then I would send the hotkey event and then finally I would get the modified text from the clipboard.
How can I trigger the hotkey event programmatically? (I know how to send key events to programs but I guess hotkeys are registered in Windows and need different handling).

hi,
May i know what is the better book to start with vc++ and MFC...as i have less time to start working on MFC in my company...
|

In my experience, just about any introductory book, save those written by Petzold, are good for learning MFC. Once you get the basics, though, I find most books beyond useless.
Having said that, my favorite book is out of print and I don't remember the name, but it started with explaining HOW MFC worked to people who already understood Windows. I then spent time writing small apps and stepping through the MFC code to fully understand what it was doing. Again, though, I'd been programming windows since 3.0 was released and had become quite an expert at it.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

In the days when we used MFC, we'd books by Jeff Prosise and Mike Blaszczak. They are great authors

Hi there.
I want to learn Multithreading programming in C++, Can some one please suggest good articles for the same.
Just FYI, I am well versed with VC++ but want to use only C++ for a specific purpose.
Thanks

There is a List of 25 primes declared in order and the above colors.
RED = 0X1000;
GREEN = 0x2000;
BLUE = 0x4000;
BLACK = 0x8000;
for ( i = 0; i < 4; i++, Color >>= 1 )
for ( j = 0; j < 25; j++, n++ )
Test[n] = primes[j] | (j << 8) | Color | (1 << (16+j));
<
primes[j] this is using one of the 25 whats in primes in order based on J.
Please what is this doing " | (j << 8) | Color | (1 << (16+j))" Can anyone help.
I know the logic works. But I can't understand what this is doing in the above loop.
Can someone please explain.
Thanks A million
