WD97: Working with Earlier Version WLLs/DLLs in Word 97

• Microsoft Word 97 for Windows

SUMMARY

This article discusses WLL/DLL compatibility between earlier versions of Word, specifically Word versions 6.x, 7.x, and their supportability in Word 97.

MORE INFORMATION

Word add-in libraries (WLLs) written for Word 6.x and 7.x run correctly in Word 97. However, the following should be noted.

New WLL creation

Word Developers writing new WLLs should use Automation rather than the wdCommandDispatch interface to access the new object model in Word 97. The wdCommandDispatch interface only supports WordBasic calls.

For additional information on using Automation with C++, please see the following article in the Microsoft Knowledge Base:

For information about wdCommandDispatch see the Word Developer's Kit, Appendix C, "Microsoft Word Application Programming Interface."

Updating String Functions in WLLs and DLLs for Word 97

Visual Basic requires external libraries to use BSTR values in string- related functions. If you have written 32-bit Word add-in libraries (WLLs) or dynamic-link libraries (DLLs) that you need to use or support in Word 97, you need to modify any string-related functions in your library and recompile it.

If you have a dial-up connection to the World Wide Web, use your Internet Browser to connect to the following Microsoft Office Developer Forum Web page to obtain more information about updating string functions in WLLs and DLLs for Word 97:
