It is not possible to include a good version of Win32 help directly with VIDE. However, a complete, fairly current version of Windows API Reference is available from Borland.
While presented by Borland as a "Windows help patch", this archive actually contains a complete (24M, 5.6M compressed) API ref in HLP format. The Borland Copyright does not allow redistribution of this file through this site, but it says nowhere that you are not allowed to download it if you don't have a Borland C++ license.
After you have downloaded the HLP file, unzip it to the same directory this file is in, and from then on, VIDE will use that file instead of this one.
