Availability

All Microsoft Windows operating systems (including Microsoft Windows CE) can run some version of Rich Edit. Rich Edit 1 is delivered in the file Riched32.dll, whereas Rich Edit 2.x, Rich Edit 3, and Rich Edit 4 are delivered in Riched20.dll. Starting with version 4.1 of Rich Edit (for Microsoft Windows XP SP1), the DLL is called "Msftedit.dll." Nevertheless, Rich Edit 4.x can run on all previous operating systems and is quite backward-compatible. Rich Edit 3 is used to emulate all the localized versions of Rich Edit 1 for Windows 2000 and Windows XP. Both Rich Edit 3 and Rich Edit 4 are single, worldwide binaries, though Rich Edit 4 has significant international improvements over Rich Edit 3 as well as TSF input support. Any localization needs (such as for pop-up menus) are delegated to the client, so that Rich Edit has almost no localized code. Table 21-1 summarizes the minimum Rich Edit support on various operating systems. All operating systems have at least Rich Edit 1.
