Parameters

TDelegateInterface: A template parameter that specifies the interface of the delegate to call when an event occurs.
TCallback: A template parameter that specifies the type of an object that represents an object and its callback member function.
TCallbackObject: A template parameter that specifies the object whose member function is the method to call when an event occurs.
TArg1: A template parameter that specifies the type of the first callback method argument.
TArg2: A template parameter that specifies the type of the second callback method argument.
TArg3: A template parameter that specifies the type of the third callback method argument.
TArg4: A template parameter that specifies the type of the fourth callback method argument.
TArg5: A template parameter that specifies the type of the fifth callback method argument.
TArg6: A template parameter that specifies the type of the sixth callback method argument.
TArg7: A template parameter that specifies the type of the seventh callback method argument.
TArg8: A template parameter that specifies the type of the eigth callback method argument.
TArg9: A template parameter that specifies the type of the ninth callback method argument.
callback: An object that represents the callback object and its member function.
object: The object whose member function is called when an event occurs.
method: The member function to call when an event occurs.

Return Value

An object whose member function is the specified callback method.

Remarks

The base of a delegate object must be IUnknown, not IInspectable.
