启用或禁用断点。
HRESULT Enable(
BOOL fEnable
);
int Enable(
int fEnable
);
参数
- fEnable
[in] 设置为非零 (TRUE) 启用或零 (FALSE) 禁用断点。
返回值
如果成功，则返回; S_OK否则，返回错误代码。 返回 E_BP_DELETED ，如果绑定断点对象的状态设置为 BPS_DELETED (的一部分 BP_STATE 枚举)。
示例
下面的示例演示如何执行显示 IDebugBoundBreakpoint2 接口的简单 CBoundBreakpoint 对象的方法。
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;
}
