I've made a simple webserver in C++ based on this one here. And this works fine.
Now, my assignment is to pass some info from this server to an html-file that later can be opened in IE or Firefox and then display info like screen resolution. Now.... This is supposed to go in an infinet do-while loop until(!) the localhost:port connection check (that I run manually from IE or Firefox) is closed! Then it is supposed to close sockets and end the run. My program however, never reaches the while-requirement for closing the connection! Why?
do
{
ClientSocket = accept(ListenSocket, NULL, NULL);
if(ClientSocket == INVALID_SOCKET)
{
cout << "\naccept failed with error: " << WSAGetLastError() << endl;
closesocket(ListenSocket);
WSACleanup();
return 1;
} // end if
else
{
cout << "\naccept() said: " << ClientSocket << endl;
cout << "\nClient connected." << endl;
} // end else
iResult = recv(ClientSocket, recvbuf, recvbuflen, 0);
if(iResult > 0)
{
cout << "\nBytes received: " << iResult << endl;
iSendResult = send(ClientSocket, recvbuf, iResult, 0);
if (iSendResult == SOCKET_ERROR)
{
cout << "\nsend failed with error: " << WSAGetLastError() << endl;
closesocket(ClientSocket);
WSACleanup();
return 1;
} // end if
else
{
cout << "\nBytes sent: " << iSendResult << endl;
} // end else
} // end if
else if (iResult == 0)
{
cout << "\nConnection closing...\n" << endl;
} // end else if
else
{
cout << "\nrecv failed with error: " << WSAGetLastError() << endl;
closesocket(ClientSocket);
WSACleanup();
return 1;
}
//GET screen resolution
int cx = GetSystemMetrics(SM_CXSCREEN);
int cy = GetSystemMetrics(SM_CYSCREEN);
// The HTML.
ofstream index;
file.open("file.html", ios::in);
if(file.is_open())
{
file<< "<html><head><title>\n";
file << "</title></head><body bgcolor='#990000'>\n";
file << "<P>Screen resolution is: " << cx << " x " << cy << "...<P>\n";
file << "</body></html>";
file.close();
}
else
{
cout << "\nThe file was not found!" << endl;
}
closesocket(ClientSocket);
} while (iResult > 0);I tried placing the accept() outside the do-while, but then it exited before I ever got near to closing the localhost-connection.
Every answere and any help is greatly appreaciated!
