Detailed Description
A variable-length sequence of "extended" (UNICODE) characters (16-bit character type). It provides editing operations with built-in memory management to make ExtendedString objects easier to use than ordinary extended character arrays. HExtendedString objects are handles to strings.
- HExtendedString strings may be shared by several objects.
- You may use an ExtendedString object to get the actual string. Note: HExtendedString objects use an ExtendedString string as a field.
