如果将 "帮助" 文件主题的上下文 ID 输入为正数, 则帮助主题将显示在 "完整" 帮助主题窗口中。If you enter the context ID of the Help file topic as a positive number, the Help topic displays in a "full" Help topic window. 如果在上下文 ID 前添加减号 ("-"), 则帮助主题将显示在 "弹出式" 窗口中。If you add a minus sign ("-") in front of the context ID, the Help topic displays in a "pop-up" window. 请务必注意, 在 Microsoft 帮助研讨会中创作时, 上下文 ID 不一定是负数。It is important to note that the context ID does not have to have a negative number when authored in Microsoft Help Workshop. 若要将该属性设置为在弹出式窗口中显示主题,一定要加上负号。You must add the minus sign when setting the property to make the topic display in the pop-up window.

如果控件的值id属性设置为 0 (默认值), Access 将使用窗体的帮助上下文帮助属性来确定要显示的帮助主题。If a control's HelpContextID property setting is 0 (the default), Access uses the form's HelpContextID and HelpFile properties to identify the Help topic to display. 如果在窗体视图之外的视图中按 F1, 或者窗体和控件的帮助上下文 id属性设置为 0, 则将显示 Access 帮助主题。If you press F1 in a view other than Form view, or if the HelpContextID property setting for both the form and the control is 0, an Access Help topic is displayed.
