Well, you could work around that by generating a Window for the scaled Image (same size etc.) and then taking a screenshot, which you can easily safe on your harddisk.
sf::Sprite spr(img);
sf::Rect<int> rect;
rect.Left = imgX1;
rect.Right = imgX2;
rect.Bottom = imgY2;
rect.Top = imgY1;
spr.SetSubRect(rect);
spr.Resize(32, 32);
// Save???
__tmainCRTStartup() I will reinstall it soon and I hope all will work again fine then.
For such a loop you should not use "for".
It is a semantic absurdity, you should use "while(true)".

QuoteI turned "Release-Mode" on and when the application start the program crashs
Do you link to the release libraries (without the "-d" suffix) in release mode ?

Hi
A socket is internally just an integer identifier, and SFML socket classes expose this through comnparison operators so that you can use a socket instance as an identifier.
About your comments :Quote- 1 is needed, I think. But I didn't see it in tutorial
I don't get it, why -1 ? For what ?QuoteThis is needed, I think. But I didn't see it in tutorial
In the tutorial, I send the ending \0 and read it back on the other side, so I don't need to append it manuallyQuoteI hoped I could give numbers to them this way. But all clients got the number 0
Yep, i is the index among the sockets which are ready at the time you read them ; most of time there will only be one socket to read, so i is always 0.
char Buffer[] = "Hi guys !";
if (Client.Send(Buffer, sizeof(Buffer)) != sf::Socket::Done)
{
// Error...
}
const unsigned int numSockets = selector.Wait();
for (unsigned int i = 0; i < numSockets; ++i)
{
sf::SocketTCP socket = selector.GetSocketReady(i);
if (socket == listener)
{
sf::IPAddress address;
sf::SocketTCP client;
listener.Accept(client, &address);
selector.Add(client);
}
else
{
char recvBuf[1024];
size_t received;
if (socket.Receive(recvBuf, sizeof(recvBuf) - 1, received) != sf::Socket::Done)
// ----------> - 1 is needed, I think. But I didn't see it in tutorial.
{
selector.Remove(socket);
std::cerr << "Error: receive" << std::endl;
continue;
}
recvBuf[received] = '\0'; // ----------> This is needed, I think. But I didn't see it in tutorial.
std::cout << "Client (" << i << ") : " << recvBuf << std::endl; // ----------> I hoped I could give numbers to them this way. But all clients got the number 0.
std::string sndBuf;
sndBuf = "Thanks for the message: ";
sndBuf.append(recvBuf);
if (socket.Send(sndBuf.c_str(), sndBuf.length()) != sf::Socket::Done)

selector.Remove(socket);
std::cerr << "Error: Send" << std::endl;
continue;
}
}
}
Width and height don't change after a rotation. They are the local dimensions of the sprite, not the axis-aligned ones.
