<P>Developers who include online help in their Access applications can choose from a variety of commercial Windows help-file authoring applications. Two of the leading products, each of which takes a different approach to help-file creation, are described in the sections that follow.

<BR>

<P>WexTech Systems' Doc-To-Help application is a collection of Word for Windows document templates (.DOT files) combined with a single Windows dynamic link library (DLL). Doc-To-Help lets you create electronic help files for an application from its formatted documentation. Although you can convert existing application manuals to Doc-To-Help's format, the most efficient use of the application requires that you first create the manuals yourself using Doc-To-Help's templates. When you complete your document, Doc-To-Help converts the document to an .RTF file and compiles the .RTF file to a Windows .HLP file. Using Doc-To-Help is one of the subjects of Chapter 22 and Chapter 23, &quot;Creating Help Files for Database Applications.&quot;

<BR>

<P>Doc-To-Help 2.0 is available now, and Doc-To-Help 1.7 was supposed to be available in January of 1996. Doc-To-Help 1.7 is for Word for Windows 2.0 and 6.0 users who work in Windows 95 or Windows 3.1. Version 2.0 is for Word for Windows 7. Features new to version 1.7 include automatic generation of contents files (.CNT files); Doc-To-Help Navigator, video, and Watermark support for 32-bit WinHelp; Doc-To-Help Navigator support in author mode; and support for Windows 95 Help second-level indexes.

<BR>

<P>Blue Sky Software's RoboHelp application, and its WinHelp Office product, are oriented to creating help files directly rather than from a preexisting application manual. Like Doc-To-Help, RoboHelp consists of Word for Windows templates and Windows DLLs. RoboHelp is less automatic in operation than Doc-To-Help, but RoboHelp lets you exercise more control over the individual elements of your help system, such as assigning special values to help context strings and ID numbers. RoboHelp is discussed in Chapter 23.

<BR>

<P>Visual C++'s OLE controls let you display graphics or play sound and music from files. Although you can use Windows OLE server applets such as Paintbrush and Microsoft Draw to create graphics, professional-quality graphic applications created by such companies as Micrografx and Corel Systems provide a host of features that aren't included in the applets that accompany Windows and its mainstream applications. The multimedia OLE server applets, Sound Recorder and Media Player, are adequate for simple multimedia databases, but you need commercial multimedia toolkits when you want to control VCRs or laserdisc players from your Visual C++ application. The following sections describe representative commercial OLE server applications that you can use with Visual C++.

<BR>

<P>CorelDRAW! is the fifth iteration of a highly successful vector drawing application that is a favorite of graphic artists. CorelDRAW! 3.0 was the first of Corel Systems' products to bundle a suite of graphics applications, including a bitmapped image editor (Corel PhotoPaint), a presentation application (CorelSHOW!), and an image database (Corel Mosaic). CorelDRAW! 4.0 added CorelMOVE!, an application that you can use to animate and add sound to CorelDRAW! images. CorelDRAW! can import images in a variety of vector formats. The CD-ROM version of CorelDRAW! includes more than 250 TrueType fonts and several thousand clip-art objects. CorelDRAW! 6 might well hold the record for the largest distribution set. It comes on many CD-ROMs!

<P>Micrografx Designer is a vector image drawing application that is oriented toward technical illustration. This venerable Windows drawing product includes an updated user interface, improved color-separation capabilities, and a 32-bit graphics engine to speed the redrawing of images. Micrografx Windows DRAW! with OLE offers a subset of designer's capabilities at a substantially lower price. Both products can import and export vector image files in a variety of common formats.

You can use Picture Publisher 3.0 to embed or link images stored in a variety of compression formats, such as JPEG (Joint Photographic Experts Group&#151;.JPG&#151;format).

The company's Enterprise Edition software for Microsoft Windows NT Server was named &quot;Outstanding New Product&quot; at the 1995 Association for Information and Image Management (AIIM) show. FileNet supports UNIX, Windows, Windows NT, OS/2, and NetWare. The Windows NT Server version of FileNet's WorkFlo Business System software, which began shipping in early 1996, is compatible with all other versions of the company's software.
