CWnd* pWnd,
BOOL bDelay = TRUE
);

[in] pWnd
The parent window of the toolbar button.[in] bDelay
TRUE if the message should be handled with a delay.

Remarks
This method extends the base class implementation, CMFCToolBarButton::OnClick, by updating the state of the drop-down toolbar.
When a user clicks the toolbar button, this method creates a timer that waits the length of time specified by the CMFCDropDownToolbarButton::m_uiShowBarDelay data member and then opens the drop-down toolbar by using the CMFCDropDownToolbarButton::DropDownToolbar method. This method closes the drop-down toolbar the second time the user clicks the toolbar button.
