Install the ActiveX control required to view the website Windows update has worked well in the past but not now. I have tried the "take these steps to solve the problem" link and find it most confusing. Therfore I can't get the Security Warningĭialog box and click Install options. When I right click on the IE Information Bar (the bar just under the address bar) I do not get the option indicating Install ActiveX Conrtol. If an application is created with a multiple-document interface (MDI), it might expose a collection object named Documents with the methods and properties in the following table.When I try Windows update from the control panel I get a message indicating I should install the ActiveX Control Collection objects let you work iteratively with the objects they manage. In the preceding figure, collection objects in Microsoft Excel are shaded. To provide an easy way to access and program the workbooks, Microsoft Excel exposes an object named Workbooks, which refers to all of the current Workbook objects.
For example, an ActiveX application based on Microsoft Excel might have multiple workbooks. Often, an application works with several instances of an object which together make up a collection object. In Automation, an event is a method that is called, rather than implemented, by an object.įor example, you might expose the following objects in a document-based application by implementing these methods and properties: ActiveX objectĪctiveDocument Application Caption DefaultFilePath Documents Height Name Parent Path Printers StatusBar Top Value Visible WidthĪctivate Close NewWindow Print PrintPreview RevertToSaved Save SaveAsĪpplication Author Comments FullName Keywords Name Parent Path ReadOnly Saved Subject Title Value You can write code to respond to such actions. The Worksheet object's Visible property determines whether the worksheet is visible.Įvents are actions recognized by an object, such as clicking the mouse or pressing a key. Properties are functions that access information about the state of an object. For example, the Worksheet object in Microsoft Excel provides a Calculate method that recalculates the values in the worksheet. Methods are actions that an object can perform. Three types of members for an object can be exposed:
When the member functions are exposed, it makes the object programmable by ActiveX clients. The following figure shows some of the objects in Microsoft Excel.Įach ActiveX object has its own unique member functions. Within Microsoft Excel, objects are organized hierarchically, with an object named Application at the top of the hierarchy. For example, Microsoft Excel exposes many objects that you can use to create new applications and programming tools. An ActiveX component is an application or library that is capable of creating one or more ActiveX objects. An ActiveX object is an instance of a class that exposes properties, methods, and events to ActiveX clients.
