This demo version contains the TMemoryMappedStream class which provides Win32 memory mapped file capability in any application. Memory mapped files provide an excellent mechanism for sharing information between applications and serve as a convienent way to quickly access information (much faster than continuously reading from and writing to the hard disk).The full version of this software package contains six classes. In addition to the TMemoryMappedStream class, there are ready-to-use classes that introduce behavior for sharing memory mapped streams between applications, within applications, and even between threads.The most powerful classes in this package are the custom memory mapped stream classes. These three classes provide a simple foundation for deriving custom memory mapped streams by descending from Delphils TStream class. Both component and application developers will find it easy to create and implement custom memory mapped streams because of the familiar TStream behavior.The included help files integrate seamlessly into Delphils OpenHelp environment, providing context-sensitive information for rapid development.
