A variety of resources are available to help MicroStation V8 application developers take advantage of Visual Basic for Application (VBA) objects.
Getting help for MicroStation V8 Visual Basic for Applications (VBA) objects can be a little tricky if you are not familiar with VBA. There are several ways to obtain help using Bentley's VBA API.
The MicroStation V8 Visual Basic for Applications Online Help tool is a comprehensive resource for working in VBA, and should be your first stop. You can launch this tool from Windows without being in MicroStation. Click on the Start button on the Windows desktop and then follow this sequence:
Programs > MicroStation V8 > Documentation > MicroStation V8 VBA
CHM help file can be found at Bentley\Program\MicroStation\MicroStationVBA.chm.
Bentley online help is a great resource for finding descriptions and examples for MicroStation VBA objects, object members and subs/functions.
Another way to find a method for an object is to utilize the Object Browser (Figure 1).
Figure 1: MicroStation V8 VBA Help dialog. The Microsoft VBA Object Browser offers the ability to search into libraries for related classes and members. For example, if you needed to know how to set the height of a text element, the steps would be:
Select the MicroStation DGN library Type in part of the member name you are looking for; in this case "height" Click on the binoculars icon to activate the search.
The results from the search will be displayed in the Search Results list box (Figure 2). In this example the goal is to set the text height of a text element, so the item of interest is the TextStyle class.

Using the library search tool can be a fast way to find information and resources while in the VBA editor. It is a quicker method than starting up Online Help and trying to sort all the results you might get from it.
Microsoft's VBA help is also delivered with MicroStation V8 (Bentley\Program\Install\VBA6\release\pFiles\Common\MSShared\Vba\Vba6\1033). If you have questions about VBA in general or Microsoft issues, this is a great first resource.
