If u use MS Visual Studio , u can Build exe for Pre and Post Script

1. Build udppre.exe

#ifndef UNICODE
#define UNICODE
#endif
#define WIN32_LEAN_AND_MEAN


#include <winsock2.h>
#include <Ws2tcpip.h>
#include <stdio.h>


// Link with ws2_32.lib
#pragma comment(lib, "Ws2_32.lib")


void main()
{
  WSADATA wsaData;
  SOCKET SendSocket;
  sockaddr_in RecvAddr;
  int Port = 22903;
  int BufLen = 128;
  
  char SendBuf[] = "RELEASE_DLL--C:\\SierraChart\\Data\\myDLL.dll"; // --------- RELEASE_DLL ------------

  //---------------------------------------------
  // Initialize Winsock
  WSAStartup(MAKEWORD(2, 2), &wsaData);

  //---------------------------------------------
  // Create a socket for sending data

  SendSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);

  //---------------------------------------------
  // Set up the RecvAddr structure with the IP address of
  // the receiver (in this example case "127.0.0.1")
  // and the specified port number.
  RecvAddr.sin_family = AF_INET;
  RecvAddr.sin_port = htons(Port);

  RecvAddr.sin_addr.s_addr = inet_addr("127.0.0.1");

  //---------------------------------------------
  // Send a datagram to the receiver

  printf("Sending a datagram to the receiver...\n");
  sendto(SendSocket,
    SendBuf,
    BufLen,
    0,
    (SOCKADDR *)&RecvAddr,
    sizeof(RecvAddr));

  //---------------------------------------------
  // When the application is finished sending, close the socket.
  printf("Finished sending. Closing socket.\n");
  closesocket(SendSocket);

  //---------------------------------------------
  // Clean up and quit.

  printf("Exiting.\n");
  WSACleanup();
  return;
}



2. Build udppost.exe


#ifndef UNICODE
#define UNICODE
#endif
#define WIN32_LEAN_AND_MEAN


#include <winsock2.h>
#include <Ws2tcpip.h>
#include <stdio.h>


// Link with ws2_32.lib
#pragma comment(lib, "Ws2_32.lib")


void main()
{
  WSADATA wsaData;
  SOCKET SendSocket;
  sockaddr_in RecvAddr;
  int Port = 22903;
  int BufLen = 128;
  char SendBuf[] = "ALLOW_LOAD_DLL--C:\\SierraChart\\Data\\MyDLL.dll"; // ------- ALLOW_LOAD_DLL --------
  

  //---------------------------------------------
  // Initialize Winsock
  WSAStartup(MAKEWORD(2, 2), &wsaData);

  //---------------------------------------------
  // Create a socket for sending data

  SendSocket = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP);

  //---------------------------------------------
  // Set up the RecvAddr structure with the IP address of
  // the receiver (in this example case "127.0.0.1")
  // and the specified port number.
  RecvAddr.sin_family = AF_INET;
  RecvAddr.sin_port = htons(Port);

  RecvAddr.sin_addr.s_addr = inet_addr("127.0.0.1");

  //---------------------------------------------
  // Send a datagram to the receiver

  printf("Sending a datagram to the receiver...\n");
  sendto(SendSocket,
    SendBuf,
    BufLen,
    0,
    (SOCKADDR *)&RecvAddr,
    sizeof(RecvAddr));

  //---------------------------------------------
  // When the application is finished sending, close the socket.
  printf("Finished sending. Closing socket.\n");
  closesocket(SendSocket);

  //---------------------------------------------
  // Clean up and quit.

  printf("Exiting.\n");
  WSACleanup();
  return;
}
