通过

IDebugBoundBreakpoint2::Enable

  • 项目

启用或禁用断点。

语法

int Enable( 
    int fEnable
);

参数

fEnable
[in]设置为非零（TRUE）以启用或设置为零（FALSE）以禁用断点。

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绑定断点对象的状态是否设置为BPS_DELETED（BP_STATE 枚举的一部分）。

示例

以下示例演示如何为公开 IDebugBoundBreakpoint2 接口的简单CBoundBreakpoint对象实现此方法。

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;
}
