HELP to Import DLL in MQL5 - Unhandled exception 0xE0434352

fnogues 2012.01.01 11:28

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"

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

    if (estado == 0)

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

    else

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

    Console.ReadKey();

    }

  }

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#

      static int initializeTrainedNN([MarshalAs(UnmanagedType.LPWStr)]string nnPath)
      {
