<P>DDF Builder lets you design and create your own data definition files (FIELD.DDF and INDEX.DDF) for Novell Btrieve tables. DDF Builder also can create new Btrieve tables. If you plan to import or attach to Access Btrieve tables created by other applications, you'll probably need DDF Builder to reconstruct the data-definition files to meet the requirements of the Btrieve driver of the Access database engine.

Using Total Access is one of the subjects of Chapter 22, &quot;Documenting Your Database Applications.&quot; All of the data that Total Access uses to create its 30 built-in reports is stored in tables that you can read with Visual C++ database applications. You also can customize Total Access's reports or create your own reports. Although Total Access was designed for Access database developers, it's equally useful for Visual C++ database applications that use the .MDB database structure.

<BR>

<P>WINGate is a unique programming toolkit that provides interprocess communication between DOS and Windows applications. WINGate's initial applications are designed to let Clipper, dBASE, and FoxPro applications running under DOS interchange data with Windows applications. The heart of WINGate is a Windows enhanced-mode virtual device driver (VxD), VWINGD.386, which lets applications running in virtual machines (VMs) communicate. WINGate uses client-server terminology in the same manner as DDE and OLE.

<BR>

<P>WinFax PRO 7.0 is a fax-management application that you can use in conjunction with a Visual C++ database application to create a fully automated fax transmission system integrated with other Windows applications, such as Word for Windows or Excel. You can use WinFax as a DDE fax server by executing Visual C++'s LinkPoke statement; the data argument consists of WinFax PRO's Recipient() function, which specifies the fax number and the other arguments needed to send a fax. Alternatively, you can manipulate WinFax PRO's dBASE IV-format phone book files as a Visual C++ Database object. The product includes a sample macro for Word for Windows that you can translate to Visual C++. WinFax PRO also includes an optical character recognition (OCR) feature that lets you convert the text of incoming or outgoing faxes to rich text format (.RTF) or ASCII text (.TXT) files.
