【摘要】 在组态软件的开发过程中,ActiveX控件已被开发者们接受并广泛使用。但是,ActiveX控件通常的使用方式是在应用程序设计阶段就被固定地嵌入到应用程序中,而在组态软件中,用户在编辑画面时对ActiveX控件的引用是随机的、未知的,因此需要在画面中动态地创建ActiveX控件。描述了在组态软件开发中ActiveX控件的动态创建方法,并讨论了由运行时许可密钥产生的问题。更多还原

【Abstract】 In the process of developing Configuration Software,it is popular to adopt ActiveX controls technique.However,ActiveX controls are usually fixed into the application software,which is not convenient to use by the Configuration Software developers,since the controls are randomly used by the users when they want to edit the views.Hence,it is very important to create the ActiveX controls dynamically.This paper describes the detailed steps of dynamic creation technique of ActiveX controls in the process of developing Configuration Software,and then discusses the runtime permission problem.更多还原
