Need some help!

[Final]

Well first of all im starting to learn winsock but I wanted to learn
Asynchronous Socket
Because I think its alot easier to handle clients information because it has its cases for client connect data recieved and data send.

But im having a problem because I dont know how it can be implanted into a program this is the code i wanted to implant but couldnt.


#define YOUR_SOCKET_MSG   WM_USER + 100      // WM_USER is a base value for user-defined messages

...

WSAAsyncSelect(theSocket, hwnd, YOUR_SOCKET_MSG, FD_READ | FD_WRITE | FD_CONNECT);.


//in window procedure:

switch (msg) {
   case YOUR_SOCKET_MSG:
      if (WSAGETSELECTERROR(lParam)) {      // If an error occurred,
         closesocket(theSocket);      // Close the socket
         WSACleanup();            // Shutdown Winsock
         return NETWORK_ERROR;         // Return NETWORK_ERROR, WSAGetLastError(), etc.
      }
      switch (WSAGETSELECTEVENT(lParam)) {   // Differentiate between the events
         case FD_READ:
       // Receive data
       break;
    case FD_WRITE:
       // Write data
       break;
         case FD_CONNECT:
       // Just connected to server
       break;
      }
      break;
}

How do I get that into a c++ program please if anyone can just make a working example of this would mke my day cuz  i looked into google as well and would give me the exact same stuff to put into a win32 api but dont know were to put it all please help!!

Save the code in a file with the .cpp extension and add the resulting file to your compilation environment (Visual Studio or Dev-C++).

Ok Well I found a better tutorial on the same subject and I finally came out with this code using the tutorial code to instert into a simple win32 api project and this is what i came out with.

#include <windows.h>
#include <winsock.h>
// the message we'll use for our async notification
#define WM_WSAASYNC (WM_USER +5)


/*  Declare Windows procedure  */

/*  This function is called by the Windows function DispatchMessage()  */

            return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
}

But now Im getting an error around this part.

WSAAsyncSelect(htons(10), hwnd, WM_WSAASYNC, FD_READ | FD_WRITE |FD_ACCEPT | FD_CLOSE)

What am i doing wrong please help me the error message dosent really help its one of those error message that dosent give you a specific and just gives an error of missing a ; or before } i tried everything but no luck could someone help me out im despriate

Have you considered that you're just not ready to do this?  The error message told you exactly what was wrong!  You are missing a semicolon before the { right next to the WSAAsyncSelect.  Also, please start using code tags when you paste code.  If you're feeling really helpful, you should also turn on lexical highlighting.

[Final]

Ok guys after alot of hard work and determination I finally got it working damn was it hard i was messing alot of things i eventually found a game that had that type of socket programming I was trying to learn but when I went into the the folder i thought the client was the server and copyed the wrong code It didnt hit me until like 40 mins later that i was using the wrong one and went into the server thinking it was the same coding as the client as socket type then i opened it and saw it was BLOCKING SOCKETS wich ticked me off but then I thout it over after i thout i was defeated then thout wy not change the client into a server and that is exactly what i did and finally got that shis working now i am one happy teen lol thanks for all trying to help me out on this i really appreciate it.

Was there a point to that post?  Was there even a coherent thought in it?  I couldn't find one in that mess...

[OT] How does one do this?

In vim, :sy on.  For the forum, you'd need a helper tool that can take lexically highlighted data in something else (BinaryChat, Visual Studio(?), vim, etc.) and generate a plaintext forum post, marking it up with [font color=] [/font] tags as it goes.  Then you post the resulting text.  You can see examples of this type of thing in the "Funny Clips from Op [vL]" thread, where some of the members post lexically highlighted chat logs.

I thought there might have been a tag.
