Accessing the registry from a dll?

[karmafx]

How can I read/write registry entries in an mfc dll? e.g. can I use the CWinApp interface ? Thanks. - KarmaFX

Thanks.. Okay, so I guess I cannot do it the MFC way ? i.e. CWinApp* pApp = AfxGetApp(); CString key = "Preferences"; CString f = pApp->GetProfileString(key,.... int l = pApp->GetProfileInt(key, .... .... ?????

Sure, you can use the CWinApp() methods, but they are slightly less flexible that the API itself. It really just depends on exactly what you are wanting storing and where.

Ok...so now my questions boils down to: How do I get a CWinApp interface within a dll ? in my experience AfxGetApp returns null in dll's... Thanks again. - KarmaFX

There are several decent registry classes here on CodeProject. Why not choose one and use it? Ignore the CWinApp stuff X|
