IDebugBoundBreakpoint2::Enable
啟用或停用斷點。
語法
參數
fEnable
[in]設定為非零 (TRUE
) 以啟用或設為零 (FALSE
) 以停用斷點。
傳回值
如果成功,則會傳回 S_OK
;否則,會傳回錯誤碼。 E_BP_DELETED
如果繫結斷點物件的狀態設定為 BPS_DELETED
(BP_STATE 列舉的一部分),則傳回 。
範例
下列範例示範如何為公開IDebugBoundBreakpoint2 介面的簡單CBoundBreakpoint
物件實作這個方法。
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;
}
