Methods

The ITfSource interface has these methods.


ITfSource::AdviseSink ITfSource::AdviseSink method
ITfSource::UnadviseSink ITfSource::UnadviseSink method

Remarks

The TSF manager has different implementations of ITfSource, depending upon how the ITfSource interface is obtained. The difference in the implementations is the types of advise sinks that can be installed with the interface. The different implementations can be obtained from the following objects.

For more information about advise sinks that can be installed by each implementation, see ITfSource::AdviseSink.

Examples

ITfThreadMgr


HRESULT hr;
ITfSource *pSource;

hr = pThreadManager->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
    //Use the ITfSource interface. 
    
    pSource->Release();
}

ITfContext


HRESULT hr;
ITfSource *pSource;

hr = pContext->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
    //Use the ITfSource interface. 
    
    pSource->Release();
}

ITfCompartment


HRESULT hr;
ITfSource *pSource;

hr = pCompartmentManager->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
    //Use the ITfSource interface. 
    
    pSource->Release();
}

ITfInputProcessorProfiles


HRESULT hr;
ITfSource *pSource;

hr = pProfiles->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
    //Use the ITfSource interface. 
    
    pSource->Release();
}

ITfLangBarItem


HRESULT hr;
ITfSource *pSource;

hr = pLangBarItem->QueryInterface(IID_ITfSource, (LPVOID*)&pSource);
if(SUCCEEDED(hr))
{
    //Use the ITfSource interface. 
    
    pSource->Release();
}
