Why do I only receive the first message I send with SDLNet?

Question

I am sending two messages from server.exe like this:

sprintf( buffer,"%d %s",1,data1);
SDLNet_TCP_Send(clientSocket, buffer, strlen(buffer)+1); // first message

sprintf( buffer,"%d %s",2,data2);
SDLNet_TCP_Send(clientSocket, buffer, strlen(buffer)+1); // second message

and I am reading messages from client.exe like this:

if(SDLNet_CheckSockets(socketSet, 0)>0)
{
    if(SDLNet_SocketReady(clientSocket)>0)
    {
        if(SDLNet_TCP_Recv(clientSocket, buffer, 5000)>0)
        {
           //there i take only first message
        }
    }
}

Why am I not receiving all sent messages in the client?

Your client code is executed only once. I think you want while loop at the inner most if-statement instead, so something like:

if (SDLNet_CheckSockets(socketSet, 0)>0)
{
    if (SDLNet_SocketReady(clientSocket)>0)
    {
        while (SDLNet_TCP_Recv(clientSocket, buffer, 5000)>0)
        {
        }
    }
}
