Mailslots

The FPS Mailslots package contains components that simplify the functionality provided by Windows� mailslots, a one-way interprocess communication mechanism. Mailslots are an excellent medium for sending information between applications running on the same machine, or for applications communicating within a network.

This package contains two non-visual components: a mailslot sender and a mailslot receiver. The mailslot sender is conceptually equivalent to a radio broadcast tower, while the mailslot receivers function as radio receivers. Initiating communication between these components is as easy as configuring a "channel" between them and sending data.

Also contained within this package is a sample application, a help file which integrates directly into Delphi, and source code for the entire package.

Memory Mapped
Streams

The demonstration component allows Delphi users to take advantage of file mapping capabilities available in Win32 operating systems without the hassle of directly using the Windows API. It provides the same behavior as Delphi's TStream descendents (i.e. TFileStream, TMemoryStream), so there is no learning curve.

Download Sample (Delphi 3-6)


The full package provides six powerful classes for creating memory mapped streams. The first three classes are ready-to-use and allow developers to accomplish tasks such as:

  • load any type of data into memory for quick access (instead of reading and writing information to and from the hard disk)
  • share information between any number of applications (excellent for preventing multiple instances of an application or transferring information between applications)
  • provide a thread-safe environment for sharing data (by using the TThreadMemoryMappedStream class)

The last three classes are by far the most powerful. These three classes provide a simple foundation for deriving custom memory mapped streams by descending from Delphi�s 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 supply detailed information for each class and integrate seamlessly into Delphi�s OpenHelp environment, providing context-sensitive information for rapid development.
