I have a library with the source code in Visual Studio 2010 C++ with struct and functions like: extern "C" __declspec(dllexport) struct Volume { double v; double a; double b; }; extern "C" { __declspec(dllexport) __int64 GetVol(__int64 id, Volume BAV); } And I use the library in Visual Studio 2010 C# 32bits Windows 8 without any error: [StructLayout([login to view URL])] public struct Volume { public double v; public double a; public double b; } [DllImport("C:\\[login to view URL]")] internal static extern Int64 GetVol(Int64 id, Volume BAV); But when I try to use the library with 64 bits or Windows 10/11 I get the error: HRESULT 0x8007007E I want to know How I have to build without any error. Thanks!

I am very proficient in c and c++. I have 16 years c++ developing experience now, and have worked for more than 7 years. My work is online game developing, and mainly focus on client side, using c++ under windows environment. I made many great projects using c++, for example, I made the tools which could convert java codes into c++ scripts, of course garbage collection included, this was very similar to a compiler, and was very complex. I also made our own mobile game using c++, I can show you the demo of client, if you like. I am very proficient in java also. I have a very good review on Freelancer.com, I never miss a project once I accept the job, you can check my review. Trust me, please let expert help you.

Hi, Are you building the C++ code in to a 64-bit DLL, before calling/using it in C#? Do you want me to help you re-build the C++ code? You DO realise that both the C# project and the invoked DLL, but be in 64-bit mode/ build type? :) Don;'t accept my proposal until we discuss your projec,t please
