Toggles the enabled state of the pending breakpoint.

Syntax

HRESULT Enable(
    BOOL fEnable
);

int Enable(
    int fEnable
);

Parameters

fEnable
[in] Set to nonzero (TRUE) to enable a pending breakpoint, or to zero (FALSE) to disable.

Return Value

If successful, returns S_OK; otherwise, returns an error code. Returns E_BP_DELETED if the breakpoint has been deleted.

Remarks

When a pending breakpoint is enabled or disabled, all breakpoints bound from it are set to the same state.

This method may be called as many times as necessary, even if the breakpoint is already enabled or disabled.

Example

The following example shows how to implement this method for a simple CPendingBreakpoint object that exposes the IDebugPendingBreakpoint2 interface.

HRESULT CPendingBreakpoint::Enable(BOOL fEnable)
{
    HRESULT hr;

    // Verify that the pending breakpoint has not been deleted. If deleted,
    // then return hr = E_BP_DELETED.
    if (m_state.state != PBPS_DELETED)
    {
        // If the bound breakpoint member variable is valid, then enable or
        // disable the bound breakpoint.
        if (m_pBoundBP)
        {
            m_pBoundBP->Enable(fEnable);
        }
        // Set the PENDING_BP_STATE in the PENDING_BP_STATE_INFO structure
        // to enabled or disabled depending on the passed BOOL condition.
        m_state.state = fEnable ? PBPS_ENABLED : PBPS_DISABLED;
        hr = S_OK;

    }
    else
    {
        hr = E_BP_DELETED;
    }

    return hr;
}
