Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)
This interface exposes the application-wide settings and device management and acts as an endpoint factory. An application must obtain and initialize this interface object before using any other UCC API features. An application obtains this interface by co-creating a UccPlatform coclass object.
Each application process can create only a single instance of this interface. After the initial creation of the platform class object, subsequent attempts to instantiate the platform class return a reference to this already created interface object.
A client must call the Initialize method to provide the platform object with the name of the client process. If platform tracing is enabled, the platform creates a tracing log file using the provided client process name. For information about enabling platform tracing, see IUccTraceSettings. The registry key <client application name> value is set with the string parameter passed to the platform in the Initialize method
The IUccPlatform interface object raises events that should be handled by an interested client. The following example initiates the interface and advises for platform events.
See _IUccPlatformEvents for information about these events. For information about advising for events, see Code Listing: Basic Event Registration and Other Helper Methods in C#.
Win32 COM/C++ Syntax
interface IUccPlatform : IUnknown
The following example instantiates a new instance of the UccPlatform class. The new class object is cast to its default interface and examined for the hash code property. The subsequent cast to
iP2 returns a reference to the initially casted interface. This is verified by comparing the int pointer to the
IUnknown interface instance values returned by the calls to Marshal.GetIUnknownForObject( ).
UccPlatform platform = new UccPlatformClass(); //2nd call to new does not create a new instance. //instead, returns the first instance again UccPlatform platform2 = new UccPlatformClass(); IUccPlatform iP = platform as IUccPlatform; IntPtr platformPtr = Marshal.GetIUnknownForObject(iP); IUccPlatform iP2 = platform2 as IUccPlatform; IntPtr platformPtr2 = Marshal.GetIUnknownForObject(iP2); //platformPtr == platformPtr2 platform.Initialize("sampleUCCPClient", null); //advise for platform events (Event source, Event sink, int identifier of e source) UCC_Advise<_IUccPlatformEvents>( platform, this);
