How to implement a Singleton in an application with DLL

Question

I have an application (in MS Visual Studio) that contains 3 projects:

• main (the one that contains the main function)

Answer 1

I believe that defining and accessing singleton instance this way might solve your problem:

Config& getInstance()
{
  static Config config;
  return config;
}

This way you also don't need to have (and call) the Initialize method, you can use constructor for initializing, that will be called automatically when you call getInstance for the first time.
