Thanks for your tip! The Sierra Chart on my end is 64-bit version. Then I am wondering whether it was because I had wrong configuration for Visual Studio. I am very new to it. Just checked: the previous dll file was built for Win32. Should I change it to x64 or other configuration? Also I am wondering whether the keyword --- extern "c" --- in the cpp file has any impact? The following is the code for DLL_Tutorial.cpp. Thanks a lot! #include <iostream> #include "DLL_Tutorial.h" #define DLL_EXPORT extern "C" { DECLDIR int Add( int a, int b ) { return( a + b ); } DECLDIR void Function( void ) { std::cout << "DLL Called!" << std::endl; } } |
