Thanks Biplab. I got the point that it is creating the instance, but what is the use of passing a namespace argument in the function GetConfigManager.
Also there are couple of statements saying this -->
mgr->Read(_T("/file_dialogs/file_new_open/filter"));
mgr->Read(_T("/file_dialogs/file_new_open/directory"), Path);
But I do not see any such folder. Where are these folders located?
