Referencing a Variable

Hi guys,

This is the situation...

I have: CustomBrowserDlg.cpp, which has this variable:

string ROOT;


I also have: File.h

which needs to be able to read the value of this variable.


What is the best to do? Move the variable to the File.h, and then #include the File.h to CustomBrowserDlg.cpp even though it's not really required inside that file, or what would you guys recommend?


Cheers!

Depends.

You can have the variable as a public member of a class and get it through a pointer to an object of that class.

eg

CMyDlg...
{
public:
  string ROOT;
....
}

CMyDlg dlg;
string AnotherString = dlg.ROOT;


If it is to be 'shared' between lots of objects then it might be appropriate to be a member variable of the app
string AnotherString = ((CMyApp*)AfxGetApp())->ROOT;


Just having it as a global variable is against the OOP philosophy.
