Winsock C++ Tutorial part 1 of 2

Here's how to make a simple Socket class to use Winsock with C++. This isn't really sufficient for a chat program, but it's a start. Will have more later.

I don't currently know much about Winsock, so annotations will be added as I figure more stuff out, or find bugs in the program.

What's the point of the SendData() function? It returns true - but it always returns true no matter if send() failed or not, why is it not checked?

if( send( ... ) != SOCKET_ERROR )

return true;

else

return false;

??? I have to say I first was positive about this tutorial and thought it was better than those out there in the internet but I get disappointed more and more..

@mySaigaAntilope It was pretty incomplete, yes. I'm sorry for the quality, it is quite old, and back then it was hard to get anybody to peer review my tutorials. Hopefully what I release in the future will be better quality, once I have time again to make tutorials (really busy w/ full time software engineering jobs since I've been out of college).

iostream? lol. I use conio and stdio

[LusikkaMage]

@vitorix24 So you're writing C code and not C++ code.

[vitorix24]

@LusikkaMage It's just libraries. C and C++ it's almost same thing. =D

[LusikkaMage]

@vitorix24 No no no no no no no. C++ is much more than an extension of libraries on top of C. C++ is a completely different language, and while C is compatible with C++, C++ is not compatible with C.

C++ is a multi-paradigm language, so on top of your basic C functionality it also includes Object Oriented designs as well as Templating.

Polymorphism, Encapsulation, Inheritance, all are parts of C++ that are not parts of C, and using C++ with only C functionality is a waste of the language.

it never ceases to depress me how little i know.

How would I add libws2_32.a to visual studios 2010? It's a linker file, yes?

I'm getting these weird errors that consist of " 1>Socket.obj : error LNK2019: unresolved external symbol __imp__socket@12 referenced in function "public: __thiscall Socket::Socket(void)" (??0Socket@@QAE@XZ)"

and whatnot

I got a question

I got the code and it works, and now I want to have that client window on an other laptop, for now I want a LAN connection but how can I do that?

I gave my both laptops their own IP adress, but my still can't find the host ;(

Do you know how to make that LAN network?

[grendel1980]

Please show us a (or is it an?) UDP example!

I'm using winsock and it randomly puts winsock 2.0 with a bunch of smiley faces in the data i send..........................­..... wtf

[zadeh79]

One thing I haven't gotten with Winsock, is getting it to run over a WAN. On my home network it ran fine., but I once tried to get it to work over internet, and it didn't work. Also file transfer is something I haven't gotten to.

@LusikkaMage What's your thought on C99?

[Sintaxx2]

@vitorix24 get your facts right ^^

@farmdve She's a 23-years-old female, as you can see in her profile.

But anyway, i have to see i saw the tutorial relative to this video, in written text.
