	IUccContainerMember pOtherMember
	IUccContainerMember pOtherMember
function CompareTo (
	pOtherMember : IUccContainerMember



A value of the IUccContainerMember* (IUccContainerMember, for a .NET application) type. This specifies the container member to be compared to.

Return Value

A value of the UCC_CONTAINER_MEMBER_COMPARE_RESULT* (UCC_CONTAINER_MEMBER_COMPARE_RESULT, for a .NET application) type. This returns the result of comparison.

Win32 COM/C++ Syntax

   IUccContainerMember* pOtherMember,
In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API.

The following example handles the OnMemberAdded container event by comparing the newly received container member with each member of a collection of previously received container members. The collection items are instances of a client application class that wraps the IUccContainerMember interface. The wrapped interface is exposed by the Member property of the application class.

void _IUccContainerEvents.OnMemberAdded(
   IUccContainer pContainer, 
   UccContainerMemberCollectionEvent pEventData)
{ = pEventData.ContainerMember;
   Boolean addMember = false;
   foreach (ContainerMember m in this.containerMembers.Values)
      UCC_CONTAINER_MEMBER_COMPARE_RESULT r = cm.CompareTo(m.Member);
         addMember = true;
   if (addMember == true)
      Console.WriteLine("New Container Member is not duplicated");

All public static (Shared in Visual Basic) members of this type are thread-safe. Instance members are not guaranteed to be thread-safe.
