IDebugBoundBreakpoint2::Enable

啟用或停用中斷點。

HRESULT Enable( 
   BOOL fEnable
);

int Enable( 
   int fEnable
);

參數

• fEnable
  [in]設定為非零 (TRUE) 來啟用，或為零 (FALSE) 若要停用中斷點。

傳回值

如果成功的話，會傳回S_OK。 否則，會傳回錯誤碼。 傳回E_BP_DELETED如果繫結的中斷點物件的狀態會設定為BPS_DELETED (屬於BP_STATE列舉型別)。

範例

下列範例會示範如何實作這個方法，如CBoundBreakpoint物件，公開 (expose) IDebugBoundBreakpoint2介面。

HRESULT CBoundBreakpoint::Enable(BOOL fEnable)  
{  
   HRESULT hr;  
  
   // Verify that the bound breakpoint has not been deleted. If deleted, 
   // then return hr = E_BP_DELETED.  
   if (m_state != BPS_DELETED)  
   {  
      // Check the state of the bound breakpoint. If the breakpoint is
      // supposed to be, but has not already been, enabled, then have the
      // interpreter set the breakpoint.  
      if (fEnable && m_state != BPS_ENABLED)  
      {  
         hr = m_pInterp->SetBreakpoint(m_sbstrDoc, this);  
         if (hr == S_OK)  
         {  
            // Change the state of the breakpoint to BPS_ENABLED.  
            m_state = BPS_ENABLED;  
         }  
      }  
      // Check the state of the bound breakpoint. If the breakpoint is 
      // supposed to be, but has not already been, disabled, then have the 
      // interpreter remove the breakpoint.  
      else if (!fEnable && m_state != BPS_DISABLED)  
      {  
         hr = m_pInterp->RemoveBreakpoint(m_sbstrDoc, this);  
         if (hr == S_OK)  
         {  
            // Change the state of the breakpoint to BPS_DISABLED.  
            m_state = BPS_DISABLED;  
         }  
      }  
      else  
      {  
         hr = S_FALSE;  
      }  
   }  
   else  
   {  
      hr = E_BP_DELETED;  
   }  
  
   return hr;  
}
