Visual Basic For Applications Excel Software With User

The user who runs any document containing VBA macros can preset the software with user preferences, much like those for internet browsers.

VBA enables developers to build user defined functions, automate processes, and access Win32 and other low level functionality through DLLs.

It was also built into Office applications up to version 2004 for Apples Mac OS X, other Microsoft applications such as Microsoft MapPoint and Microsoft Visio; as well as being at least partially implemented in some other applications such as AutoCAD, WordPerfect and ArcGIS.

It supersedes and expands on the capabilities of earlier application-specific macro programming languages such as Words WordBasic, and can be used to control many aspects of the host application, including manipulating user interface features, such as menus and toolbars, and working with custom user forms or dialog boxes.

VBA can also be used to create import and export filters for various file formats, such as ODF.

It can, however, be used to control one application from another using OLE Automation.

For example, it is used to automatically create a Word report from Excel data, in turn automatically collected by Excel from polled observation sensors.

The VBA IDE is reached from within an Office document by pressing the key sequence F11.

It has the ability to use (but not create) ( ActiveXCOM ) DLLs, and later versions add support for class modules.

Despite its resemblance to many old BASIC dialects (particularly Microsoft BASIC, from which it is indirectly derived), VBA is not compatible with any of them except Microsoft Visual Basic, where source-code of VBA Modules and Classes can be directly imported, and which shares the same library and virtual machine.

Compatibility ends with Visual Basic version 6; VBA is not compatible with VB.NET.

VBA is proprietary to Microsoft and, apart from the COM interface, is not an open standard.

A listing of the object model is found by opening the MacroVBA editor in the target application and then using View to open the Object Browser (F2).

One way to learn the terms and syntax of the object model is to use the macro recorder to record the steps taken to achieve a desired result using the mouse and menus of the application.

Unfortunately, the macro recorder does not always record everything (particularly for graphs), and some applications employing VBA do not provide a recorder at all.

Use of debugging tools to discover VBA constructs for some cases where the macro recorder does not work are described by Jelen and Syrstad, 6 but some steps may remain obscure.

This documentation can be examined from inside the VBA development environment using its Object Browser.

For example, a VBA program written to automate Microsoft Word cannot be used with a different word processor, even if that word processor hosts VBA.

References to the different libraries must be created within the VBA client before any of the methods, objects, etc.

These application objects create the OLE link to the application when they are first created.

Commands to the different applications must be done explicitly through these application objects in order to work correctly.

References to the Excel, Word, and Microsoft Outlook libraries can also be created.

This will allow creating an application that runs a query in Access, exports the results to Excel, formats the text, then writes a Mail merge document in Word that it automatically e-mails to each member of the original query through Outlook.

In this example, Microsoft Outlook contains a security feature that forces a user to allow, disallow, or cancel an e-mail being sent through an automated process with a forced 5 second wait.

Using VBA, most of the security features lie in the hands of the user, not the author.
