Remarks

The defaultcollelem C++ attribute has the same functionality as the defaultcollelem MIDL attribute.

Example

The following code shows an interface method using the defaultcollelem attribute:

// cpp_attr_ref_defaultcollelem.cpp
// compile with: /LD
#include <unknwn.h>
[module(name="MyLib")];
[object, uuid("00000000-0000-0000-0000-000000000001")]
__interface IMyForm 
{   
   [propget, id(1), bindable, defaultcollelem, displaybind, 
   defaultbind, requestedit] HRESULT P1([out, retval] long *nSize);
   [propput, id(1), bindable, defaultcollelem, displaybind, 
   defaultbind, requestedit] HRESULT P1([in] long nSize);
};
