You will need to adapt this to your system.

You will need to have installed the compiler from Sierra Chart.

Save this file as build.ps1 and run it from powershell with: .\build.ps1

function Send-UdpDatagram
{
Param ([string] $EndPoint,
[int] $Port,
[string] $Message)

$IP = [System.Net.Dns]::GetHostAddresses($EndPoint)
$Address = [System.Net.IPAddress]::Parse($IP)
$EndPoints = New-Object System.Net.IPEndPoint($Address, $Port)
$Socket = New-Object System.Net.Sockets.UDPClient
$EncodedText = [Text.Encoding]::ASCII.GetBytes($Message)
$SendMessage = $Socket.Send($EncodedText, $EncodedText.Length, $EndPoints)
$Socket.Close()
}

Send-UdpDatagram -EndPoint "127.0.0.1" -Port 22903 -Message "RELEASE_DLL--C:\SierraChart\Data\mydll.dll"

cmd.exe /c "C:\SierraChart\Data\VisualCCompile.Bat"

Send-UdpDatagram -EndPoint "127.0.0.1" -Port 22903 -Message "ALLOW_LOAD_DLL--C:\SierraChart\Data\mydll.dll"

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;
}
