Initializing a const in the view from Doc

Hiya

I have an MFC SDI application.

In the View I have a variable

const CString ViewMessage

I want to initialize this variable from a value in the Doc e.g. DocMessage.

As the variable is const I have to initialize it in the constructor list. How do I do this?

I tried adding

ViewMessage(GetDocument()->DocMessage)

to the View initialization list and it compiles. Unfortunately, when I run it, it just causes an assertion and loads of memory leaks.

Can anybody help?

John

Hi IssacJones,

in general it's correct to initialize const members in the initialization list - IMO the problem is that 'GetDocument' doesn't return a valid documen pointer (I guess it returns NULL) since the CView::m_pDocument (which is returned by GetDocument) isn't yet initialized.

Unfortunateley I don't know a workaround for this except not using const for that member ...
