I have seen header files that include each other, a very bad idea, but they usualy solve the problems that presents with forward declarations and the like.

IMO, if header files need include each other, then their contents either belong together in the same header file, or need to be separated into more header files so you have more fine-grained control.

Seen a #include "stdafx.h" Roll eyes | :rolleyes:

lately, and what stdafx.h contains?

What I DON'T like about that rule is, I locate a header file with a particular function, and I spend the next twenty mintues including about 20 more header files to resolve all the type definitions, data structures, base types and other crap required to use the function from the first header.

Sorry for the delay, I was entertaining myself with a Pokemon game... Blush | :O

Anyways... Yeah, now I'm getting an error saying that the network variable was already declared in server.obj... What?! It ain't on server.cpp... How can it be on the obj file? WTF | :WTF:

The only declaration I can find is this one:

} network; (after the class declaration)

Why is it already declared on server.obj? Dang... Mad | :mad:

Thanks!

BTW: I have removed Globals.h, and there's no more includes depending on each other...

Maybe I am doing it right, but it's a problem with SDL or SDL_net? OMG | :OMG:

If you declare a variable in a header file and include that header file into more than one source file, then you will get the 'already declared' types of errors and warnings.

It is best to ONLY define the variable in a single header file and declare an instance of the variable in a single source file.

For example, your header file 'SuperDuperClass.H' would have something like this in it:

// this is the instance definition, leting oter source files know there is
// a variable g_MySuperDuperClass of type SuperDuperClass out there somewhere
extern SuperDuperClass g_MySuperDuperClass;

And a single source file somewhere in your project would have this near the top:

#include "SuperDuperClass.H"

// this is the instance declaration
SuperDuperClass g_MySuperDuperClass;

But now I'm facing these, which where after the previous error: Frown | :(

Go to the project settings, I think it is under a 'Link' tab, and find a checkbox labeled 'ignore default libraries' or something similar to that, and check it.
Then try your build again.

Try using some of the numeric conversion functions, for example itoa(), ltoa().

Or you could use the sprintf() function. That's good for getting secific formatting.

Hi there.

While sprintf works, it is really a C solution. I just wanted to show you a C++ solution for creating a string to display by using streams.

<br />
#include <sstream><br />
<br />
// your numerical data <br />
double num1 = 3.143;<br />
<br />
// an output stream<br />
std::ostringstream outStream;<br />
std::string        outString;<br />
<br />
outStream << "Value of double is : " << num1;<br />
<br />
// if you want a standard c++ string from the stream<br />
outString = outStream.str();<br />
<br />
// VC++ stuff.  Lets write the string to a label (need to create a System::String)<br />
label1->Text = gcnew String(outStream.str().c_str());<br />

Using the ostringstream, you will not have to worry about the size of your char array, or have a ptr to char and do any memory allocation/cleanup. All done for you.

Cheers

If you want to take account of the taskbar, use SystemParametersInfo with SPI_GETWORKAREA. Bear in mind that on a multi-monitor system, each monitor can have a different resolution.

I have been putting it off for a month now because i couldnt find a real good place to start studying for this. So i figured I would ask you all here if you recommend some nice places or books to read to work with Internet programming using Windows Sockets or (if you think it is better) any other socket programming.

obviously if at all possible I'd like to study Windows sockets 2, but 1.1 is ok I guess. Remember before you say go read MSDN I am really new to Internet/Network Programming, so something that will guide me is truly the most helpful.

Thanks

What does being new have to do with (not) reading MSDN? In addition to that, I would suggest Googling for specific topics, and perusing this section of CP.

Learn winsock programming via books. I highly recommend Network Programming for Microsoft Windows Second Edition by Anthony Jones and Jim Ohmund.
