In document-view architectures views don't directly communicate; all communication occurs via the document. If view 1 needs to “talk” to view 2 then view 1 should update the document and the document will notify all applicable views, in this case view 2.

I assume you're using MFC. From a view can can get access to its document via the
GetDocumentfunction the wizard generates for you in the view class. Your document class should provide functions to modify the state of the document. The functionCDocument::UpdateAllViewson the document is used by the code in the document (or view) to inform all views (thepSenderparameter can be used to exclude the sending view if required) of a change in the state of the document.Steve
