事件來源 (Visual Studio SDK)

 

如需 Visual Studio 2017 的最新文件請參閱 Visual Studio 2017 文件。

有兩個來源的事件︰ 偵錯引擎 (DE) 工作階段偵錯和管理員 (SDM)。 從 DE 傳送的事件會有一個非 NULL 引擎，而從 SDM 傳送的事件有 NULL 引擎。

範例

下列範例示範如何傳送IDebugProgramCreateEvent2從 SDM 至 DE。

CDebugProgramCreateEvent* pProgramCreateEvent = new CDebugProgramCreateEvent();  
if (FAILED(pCallback->Event(m_pEngine, NULL, m_pProgram, NULL, pProgramCreateEvent, IID_IDebugProgramCreateEvent2, EVENT_ASYNCHRONOUS)))  
{  
   // Handle failure here.  
}  
]  
  
CEvent * pProgCreate = new CEvent(IID_IDebugProgramCreateEvent2, EVENT_ASYNCHRONOUS);    
pProgCreate->SendEvent(pCallback, m_pEngine, (IDebugProgram2 *)this, NULL);  
  
HRESULT CEvent::SendEvent(IDebugEventCallback2 *pCallback, IDebugEngine2 *pEngine, IDebugProgram2 *pProgram, IDebugThread2 *pThread) {    
   HRESULT hr;    
  
   if (m_dwAttrib & EVENT_STOPPING)    
   {    
      hr = SendStoppingEvent(pCallback, pEngine, pProgram, pThread);    
   }    
   else if (m_dwAttrib & EVENT_SYNCHRONOUS)    
   {    
      hr = SendSynchronousEvent(pCallback, pEngine, pProgram, pThread);    
   }    
   else    
   {    
      assert(m_dwAttrib == 0);    
      hr = SendAsynchronousEvent(pCallback, pEngine, pProgram, pThread);    
   }    
  
   return hr;    
}    
  
HRESULT CEvent::SendAsynchronousEvent(IDebugEventCallback2 *pCallback, IDebugEngine2 *pEngine, IDebugProgram2 *pProgram, IDebugThread2 *pThread) {    
  
    HRESULT hr;    
  
   // Make sure the CEvent object running this code is not deleted until the code completes.    
   AddRef();    
  
   pCallback->Event(pEngine, NULL, pProgram, pThread, (IDebugEvent2 *)this, m_riid, m_dwAttrib);    
  
   // No error recovery here.    
   hr = S_OK;     
  
   Release();    
   return hr;    
}
