    Permission Denied

    I am writing a server for my game that I am making. Up to about 2 minutes ago, it compiled fine. Now, however, it gives me an error and I have changed nothing.

    Main Code:
    Code:
    #include <windows.h>
    #include <winsock2.h>
    #include <fstream>
    #include "definitions.hpp"
    using namespace std;
    
    LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);
    
    char szClassName[ ] = "DNMasterServer";
    HWND hwnd, connectlog;
    WORD sockVersion;
    WSADATA wsaData;
    int iResult;
    SOCKET m_socket;
    SOCKET AcceptSocket;
    HANDLE connectthread;
    char mstrmessage[2048];
    
    void WaitConnection() {
        while (1) {
                AcceptSocket = SOCKET_ERROR;
                while (AcceptSocket == SOCKET_ERROR) {
                    AcceptSocket = accept( m_socket, NULL, NULL );
                }
                m_socket = AcceptSocket;
                send(m_socket, mstrmessage, strlen(mstrmessage), 0);
                closesocket(m_socket);
                closesocket(AcceptSocket);
                SendMessage(connectlog, LB_ADDSTRING, 0, (LPARAM) "Master Message Sent...");
        }
        ExitThread(0);
    }

    I was doing the exact same thing before and got the same warning for the second line, but now it tells me the other two things.

    I have not changed anything in my code since I last got it to compile. I have tried to rebuild the project and that didn't work. I tried closing it and reopening it and that didn't help. I have tried opening another project and then coming back to this one and that didn't help.

    I am using Dev-C++.


    Oh and I know that the code I use for checking connections the server is bad I am going to fix that.

    I am guessing that your program is still running and the linker can't overwrite the executable. Check your processes and terminate the process if necessary.

    That got it. I had to close it under bad circumstances.

    Thanks.
