SYMPTOMS

ATL projects built for MinDependency will still need Atl.dll if they use ATL control containment code.

Back to the top

CAUSE

ATL's control containment implements interfaces that are described by the type library in Atl.dll.

RESOLUTION

Include the Atl.dll file.

STATUS

This behavior is by design.

Back to the top

ATL's control containment implements two dual interfaces, IDocHostUIHandlerDispatch and IAxWinAmbientDispatch, as a part of the control container. Because the dual interfaces are implemented using IDispatchImpl, they delegate to the type library for implementation of IDispatch methods. This requires the type library describing these interfaces to be registered. This type library exists in Atl.dll.
