HELP to Import DLL in MQL5 - Unhandled exception 0xE0434352

[fnogues]

I did a DLL in order to comunicate MT5 with ENCOG using SVM, but when I run the MQL5 I get "Unhandled exception 0xE0434352"

I did a C# program in order to check the problem but C# is running perfectly with the same DLL.

The MQL5 program now it is very simple. I get "Call to Encog DLL" message and after that I get the "Unhandled exception 0xE0434352"

   int Estado = inicio();
   Print("Exit DLL");
   return(0);
  }

The C# program also it is very simple and I get the message "Ok DLL Encog..."

using System.Linq;

using System.Text;

using System.Runtime.InteropServices;

namespace ConsoleApplication_Test

{

class Program

{

  [DllImport("ENCOG_MT5.dll", EntryPoint = "inicio")]

  public static extern int inicio();

  static void Main(string[] args)

  {

    int estado = inicio();

    if (estado == 0)

       Console.WriteLine("Ok DLL encog...");

    else

       Console.WriteLine("Problems in DLL encog...");

    Console.ReadKey();

    }

  }

}

I have the same Problem ,

 

I can import the dll successfully in my MQL 5 code , and can call a simple method that just return an integer successfully ,

but when i am trying to call the method that creates the neural network i got the following  exception

"2013.08.17 22:35:40 NeuralEncogIndicator (EURUSD,H1) Unhandled exception 0xE0434352"

what could be the reason ? and how can i trace the dll functions ??

 

Thanks,

I also have the same problema that last user.

What can I do to fix IT?

MT5 is now available for brazillians and I'm trying to embed encog to my trade systems.

Tks,

[Stanislav Korotky]

Are you sure that ENCOG_MT5.dll uses wchar type for those method parameters which are strings in MQL5? If it's char, the dll should be recompiled.

Function declaration on C#

      [DllExport("initializeTrainedNN", CallingConvention = CallingConvention.StdCall)]
      static int initializeTrainedNN([MarshalAs(UnmanagedType.LPWStr)]string nnPath)
      {
          neuralnet = new NeuralNET(nnPath);

          if (neuralnet.network != null) return 0;
          else return -1;

      }

Reference on MQL5

#import "EncogNNTrainDLLVS2010.dll"
   int initializeTrainedNN(string nnFile);
