In sock.cpp you have the following lines :
SOCKET theClient;
SOCKADDR_IN clientAddr;
int ssz = sizeof(struct sockaddr);
theClient = accept(m_socket,(LPSOCKADDR)&clientAddr,&ssz);
if (theClient == INVALID_SOCKET) {
int nret = WSAGetLastError();
throw CSocketException(nret, "Invalid client socket: Accept()");
}
CSocket *sockClient = new CSocket();
sockClient->SetSocket(theClient);
sockClient->SetClientAddr(clientAddr);
m_socket is the socket which listens on the given Port. So m_socket is a ListenSocket
theClient is also a Socket which will store an Incomming-Connection from a Client.
clientAddr is a structure which will be filled with information during the accept()-function.
After accept was executing, you have the IP and Port into this strucure.
At the end you see that clientAddr is stored inside the class, so you can access from out
your source code, to the CServerSocket class and get the Client-Information-Structure.
You get the IP in plain text with
char TheClientIP[16]="";
strcpy(TheClientIP,inet_ntoa(...->sin_addr));
Good luck

Your response is always so fast.
I really appreciated your explanation about the source.
It's really easy to understand.
I think I got what it mean now.
But still doesn't know what is inside (...->sin_addr).
because m_clientAddr is an private object,
so I can't access it.

I solved it, thanks to your assistance.
Your answers really help me.
In main function, I added these lines :
CSocketAddress *addrs = sock->GetAddress();
ClientAddress = addrs->GetSockAddrIn();
buffer2 = inet_ntoa(ClientAddress.sin_addr);
Thanks again for your assistance.

Hi all,
Actually i want to write a html file or .html page and i don't know how to do it using MFC. I know how to write a .txt file using CStdioFile class and using WriteString API's. Can any body tell me how to do it.
Thanks in advance

1. You must know the HTML tags.
2. While saving the file just specify the extension as .htm / .html.
And you are done with writing an .html file.

NTDLL.dll ? That's a very descriptive error message 
If you want some help, you have to provide at least some bit of usefull information. So, what happens exactly ? What does this message say exactly ?

Use your debugger to inspect the variables and see exactly what happens.

You can create font object (member variable) and use SetFont() API of ListCtrl
josip cagalj wrote: how to set background color to an a dialog
Map the WM_CTLCOLOR and write,
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if( nCtlColor == CTLCOLOR_DLG )
{
hbr = (HBRUSH) GetStockObject( BLACK_BRUSH ); // or m_brushDlg.GetSafeHandle();
}
return hbr;

Thanks for replay.
I do this:
<br />
CDC *pDC=GetDC();<br />
CFont VelikiFont;<br />
int nHeight;<br />
nHeight = -MulDiv(10, pDC->GetDeviceCaps(LOGPIXELSY), 72);<br />
VelikiFont.CreateFont(<br />
nHeight,
0,
0,
0,
FW_BOLD,
FALSE,
FALSE,
FALSE,
DEFAULT_CHARSET,
OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,
PROOF_QUALITY,
FIXED_PITCH | FF_MODERN,
"Courier New"
);<br />
<br />
ReleaseDC(pDC);<br />
m_List.SetFont(&VelikiFont);
But I dont get what I wont. When I change 'nHeight' parameter I don't get bigger font, but more space between rows!
Regarding background color Can I set the color (like RGB value or something) instead of choosing type of stock object!
Once again thanks for replaying!

Font object should be member or global. That is it should not be local.

In my sample I have placed a comment regarding this.
You have to keep a brush as member or global.

I create the Folder as "CreateDirectory(L"c:\\mydirectory", NULL);"
Give your suggestion to Reading and Writing the data from Folder.

There are a lot of ways, including STL streams, MFC classes such as CFile and CStdioFile, and the Win32 functions like Read() and Write().

Hello Friends,
Currently in free time i was just checking the C#.Net. and when I try to make the sample porject in C# in Visual Studio 2005 I amazed by the IntelliSense.It works so fast and nicely in C# but it doesnt working in the same manner when I am working on Win32 programming. Is there any way i can change the IntelliSense to work better.

Hi,
i think no. But you can set some preferences into the Settings-Menu of VS2005.
Propably some checkboxes de-/activates some specials which takes more time

Hello,
I need the answers for the following questions:
1. I have a class (ex: Test) contains 2 variables,then I am creating 2 objects of that class. How many copies of the variables are stored in memory?
2. What will be the output of the following program:
int* fun()
{
int a;
return &a;
}
suppose, if i assign a value for the variable "a" (ie int a=10) what will be the output?
Thanks in advance for the solutions.

1) two: one copy for each object. Do you want one common object for every class? Then you have to use a static variable.
2) it returns the address of the variable 'a'...it is not important what it contains (10 , 20 or 0). You can look at the contents of (&a) with *( &a )
