Global application object

[Birger Thureson]

I want to retrieve my own implemented variables in the CWinApp-derived class from another class (The variables hold values from an INI-file).


How do I refer to the one and only global application object from another implemented class ( i.e CString s=theApp.myvariable )???


Please help me!

Try to use :


extern CString s;


in other file

One way is to use an extern declaration like this

class CMDIApp :public CWinApp

{//...}

extern CMDIApp theApp;

1) if you only want to read them once, the place is InitInstance

2) Create a static class, holding only static members and static functions

3) In InitInstance read from INI file and poke the values into the static class

4) Access the values from this static class whereevere you need them

5) Lycka till

Use AfxGetApp(), which returns a pointer to the application object, and cast it to your derived class like this:


CMyApp* pMyApp = dynamic_cast (AfxGetApp());


Now you can access your derived application public members:


int value = pMyApp->GetValue();
