Hi,

Why to open a command prompt session when there is an API function for doing this:

procedure NetSendMessage(const ToComputer, FromComputer, Mess: string);
type
  TNetMessageBufferSendFunction = function(servername, msgname, fromname: PWideChar; buf: PWideChar; buflen: Cardinal): longint; stdcall;
var
  NetMessageBufferSend: TNetMessageBufferSendFunction;
  DLLHandle: THandle;
  Name, From, Buf: WideString;
begin
  DLLHandle := LoadLibrary('NETAPI32.DLL');
  if DLLHandle <> 0 then begin
    try
      @NetMessageBufferSend := GetProcAddress(DLLHandle, 'NetMessageBufferSend');
      if @NetMessageBufferSend <> nil then begin
        Name := ToComputer;
        Buf := Mess;
        From := FromComputer; // you may even set
        NetMessageBufferSend(nil, PWideChar(Name), PWideChar(From), PWideChar(Buf), Length(Buf) * SizeOf(WideChar));
      end;
    finally
      FreeLibrary(DLLHandle);
    end;
  end;
end;

Regards, Geo
