Create a DLL in c++

[Zool]

I work on a project in VC + + and I'd like to use that DLL in another project. My problem is that the creation of DLLs in all the documents of c program but no creation of dll with classes. How to create a DLL while keeping the appearance Object Oriented for generic classes.

Create a new project "Dynamic Linked Library" (or is it under VS + +). Otherwise, it's the same thing with a normal project, except that there is no macro to the name of each class that you exported (generated automatically by VS)

 NOMDELADLL_SHARED_EXPORT class ClassName

DLLs make your program modular, The file formats for DLLs are the same as for Windows EXE files.Microsoft Visual C++ (MSVC) provides a number of extensions to standard C++ which allow functions to be specified as imported or exported directly in the C++ code.In fact once you've created your DLL, it should be placed in the directory of your executable and the "linker" to use it in your program.
