Remarks

An edit context object is created by calling ITfDocumentMgr::CreateContext. Often, a text service uses the currently active edit context. The currently active edit context is the edit context at the top of the stack of the active document manager.

Examples


HRESULT         hr;
ITfDocumentMgr  *pFocusDoc;

hr = pThreadMgr->GetFocus(&pFocusDoc);
if(SUCCEEDED(hr))
{
    ITfContext *pContext;

    hr = pFocusDoc->GetTop(&pContext);
    if(SUCCEEDED(hr))
    {
        //Use the context. 
        
        pContext->Release();
    }

    pFocusDoc->Release();
}
