Passing strings from DLL to MQL5

[Suren Expert]

Hi, 

   I have developed a DLL in VS 2010 ( Uses Unicode Character Set ) and am trying to pass string (wchar_t*) from the DLL  function as return value but have failed in every attempt. Need help to get this issue resolved. 

e.g DLLAPI wchar_t* __stdcall cMySqlVersion()

Hi,

Try this:

extern "C" __declspec(dllexport) wchar_t* cMySqlVersion()

Here is the function

extern "C" __declspec(dllexport) wchar_t* __stdcall cMySqlVersion()

{

 return ("MQLMySQL v2.0");

}

A small correction:

extern "C" __declspec(dllexport) wchar_t* __stdcall cMySqlVersion()

{

 return (L"MQLMySQL v2.0");

}
