I am trying to get a CRichEditCtrl by creating a member variable

CRichEditCtrl &m_RichCtrl

and then call m_RichCtrl=GetRichEditCtrl();

The compiler complains:error C2758: 'm_RichCtrl' : must be initialized in constructor base/member initializer list

Can anyone explain why and how to fix it?

Thanks, Rick

you cannot declare a reference and assign it later. I suggest to declare and assign ad hoc as a local variable, like in:

// declare locally
CRichEditCtrl &richCtrl=GetRichEditCtrl();
// use it here
richTrl.DoSomething();

or even you can use directly without using a variable:
GetRichEditCtrl().DoSomething();

Well, as I stated, you cannot declare an "unreferenced" reference in C++.
It has to be referenced inmediately. It doesn't work like pointers that you can declare without pointing to anything.
