IComponentTypes::get__NewEnum

The get__NewEnum enumeration method supports For...Each loops in Automation clients.

Syntax

  HRESULT get__NewEnum(
  IEnumVARIANT**  ppNewEnum
);

Parameters

ppNewEnum

[out] Address of an interface pointer to an IEnumVARIANT object that will receive the new collection.

Return Values

Returns S_OK if successful. If the method fails, error information can be retrieved using the standard COM IErrorInfo interface.

Remarks

This method is provided to enable scripting and Visual Basic applications to iterate through the collection in a For...Each loop. C++ applications should use the IComponentTypes::EnumComponentTypes method.

The returned IEnumVARIANT interface is not thread safe, because it is intended primarily for use by Automation clients. Clients should not call methods on the interface from more than one thread.

Requirements

Header: Dshow.h.

Library: Quartz.dll.
