DOC: PENWIN.DLL Requires Windows 3.1

The information in this article applies to:

• Microsoft Windows for Pen Computing version 1.0

In version 3.1 of the Microsoft Windows Software Development Kit (SDK), the section of the TIPS.HLP online help file that describes the contents of the redistributable files directory incorrectly states that all the dynamic- link libraries (DLLs) in the directory operate under Microsoft Windows versions 3.0 and 3.1.

PENWIN.DLL implements the Pen Extensions under Microsoft Windows 3.1. The Pen Extensions to Windows, and the OEM product Microsoft Windows for Pen Computing, each require the Windows 3.1 environment. Applications based solely on the Pen Extensions will not run under Windows 3.0. An application that uses the Pen Extensions should do one of the following:

• Use the Resource Compiler /31 switch to prevent the application from running under Windows 3.0.
• Code the application to dynamically configure itself according to the installed version of Windows.
