CComUnkArray Class

This class stores IUnknown pointers, and is designed to be used as a parameter to the IConnectionPointImpl template class.

template<
   unsigned int nMaxSize
>
class CComUnkArray

Parameters

• nMaxSize
  The maximum number of IUnknown pointers that can be held in the static array.

Remarks

CComUnkArray holds a fixed number of IUnknown pointers, each an interface on a connection point. CComUnkArray can be used as a parameter to the IConnectionPointImpl template class. CComUnkArray<1> is a template specialization of CComUnkArray that has been optimized for one connection point.

The CComUnkArray methods begin and end can be used to loop through all connection points (for example, when an event is fired).

See Adding Connection Points to an Object for details on automating creation of connection point proxies.

Note   The class CComDynamicUnkArray is used by the Add Class wizard when creating a control which has Connection Points. If you wish to specify the number of Connection Points manually, change the reference from CComDynamicUnkArray to CComUnkArray< n >, where n is the number of connection points required.
