Hello,
When i was using c# i was simply adding refence to a dll and start to use its public functions.
Now i am using c++ 2008  (all of my code is native c++). And i want to use a dll that i have created in my project.  Can you show me how to import dll in native c++ ?
How should i prepare my dll l so that it will be able to export its functions ?

Thank you.

In your code that you want to export functions or objects define them with this syntax
  __declspec(dllexport) void myfunc(/* insert your arguments */);
and in your code that you want to use the exported functions or objects, you need to declare them with this syntax
  __declspec(dllimport) void myfunc(/* insert your arguments */);
Usually you put all the declarations in a header (.h) file like myfuncs.h and then in your code where you use the exported functions, include the header file like this
  #include "myfuncs.h"
C++ also includes a linking step unlike C# where the calling .exe or .dll needs to be linked with the .lib file from the exported dll. So make sure you include this, otherwise you will get an "unresolved external" error.
