It’s like a minefield of bugs and issues: command bars behave differently in different Office applications or become disconnected suddenly, Outlook hangs in the Task Manager or doesn’t fire the events you rely upon, Office updates change the sequence of events, and many, many more. If you’ve never done Office development before, you’ll be in a shock because while the user’s side of any Office application is remarkably stable and robust, the application’s object model is a completely different story. What are the typical problems with Office add-ins? Here you find definitions of the types that all Office applications share: COM add-ins, command bars and controls, custom task panes, ribbons, etc. To understand user interface options, you select Office in the topmost combo of the Object Browser. However, I insist on using the Object Browser: it is the essential step of getting into the insight of the Object Model of any Office application. I understand that you may never have used (and will probably never use) VBA. When you click the function above and press F1, it appears that the Index parameter can accept numeric and string values either the index position of the Bookmark in the Bookmarks collection or a bookmark’s name. Like Object variables, Variant variables can accept almost any data types. The Variant data type is a predecessor of the Object data type in. That is, the declaration above should read as follows:įunction Item(Index as Variant) As Bookmark

In such situations you should know that the Browser omits the Variant keyword. However, the declaration doesn’t reveal the type of the Index parameter. It defines the Item function which returns a value of the Bookmark type. Consider the following declaration in the Word object model, note that this pattern is often used in other object models: If you have no or little experience in VB6 (VBA) programming, please note that some declarations don’t specify the types of parameters and/or return values. The Object Browser reveals all the declarations in VBA syntax. Those help articles are the shortest way to understanding of the object model. When you find an object of interest, you click it and press F1 to get the help article related to this object. There is a restriction though: it doesn’t search through a method’s parameters. The Object browser allows searching through any or all object models. You can restrict the browser to show the public interfaces of a single object model: use the topmost combo to select, say Outlook, Word, Excel, or MSProject. The Object Browser provides you with public classes, their properties and methods as well as with public enumerations for all object models that the currently open document refers to (use Tools | References to add a new reference). When in the IDE, you choose View / Object Browser in the menu or press F2. If it is the case, please refer to Programmer’s Reference or MSDN. Note that some Office applications, recent ones mainly, do not provide IDE. Having run the host application, you open the environment by choosing the Tools / Macro / Visual Basic Editor menu item or by pressing Alt + F11. However, where does an object model live? The best way to study any Office Object model is the Object browser available in the Visual Basic IDE. Here is one of the most frequently asked questions on the Add-in Express forum: Is it possible to add a custom page to the Tools | Options dialog in Excel? Our standard answer is: It is not possible because the Excel Object Model doesn’t provide any way for this.

The user is allowed to enable or disable COM add-ins via COM Add-ins dialog: Obviously, this requires administrative privileges.Ī number of other COM interfaces require implementation if your add-in customizes the Office 2007 Ribbon user interface (IRibbonExtesibility), creates custom task panes (ICustomTaskPaneConsumer), and so on.

To run for all users on the current PC, Office COM add-ins must be registered in HKEY_LOCAL_MACHINE. NET developer, Office add-ins are class libraries implementing the IDTExtensibility2 COM interface and registered in an appropriate registry branch in HKEY_CURRENT_USER. Naturally, to be executed in this way add-ins should conform to some rules.įor the. COM add-ins run within the process of their host application and use programmatic interfaces provided by the host in order to access currently open documents and modify their contents or react to user actions. Starting from version 2000, Office applications allow COM add-ins to customize their user interface with toolbars, menus, context menus, ribbons, task panes etc.
