 # Event sources (Visual Studio SDK)
-There are two sources of events: the debug engine (DE) and the Session Debug Manager (SDM). Events sent from a DE have a non-NULL engine, while events sent from the SDM have a NULL engine.  
-  
-## Example  
- The following example shows how to send the **IDebugProgramCreateEvent2** from the DE to the SDM.  
-  
-```csharp  
-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);
