This book has been revised and over 180 pages added to take into consideration the migration of OLE to COM or DECOM and the very heavy emphasis on the COM technology by Microsoft. The book still carries out the workbook format developed by Platt in the previous edition and his earlier book The WIN 32 API from Scratch. The revision will have an updated CD-ROM with an increase in working sample code that the reader/user can cut and paste into their own applications.
