«« Site Rescued »»

While the site is still going to move from its current host, a new site will now take its place. More Info.

The new site may have less content, but the core will now remain. And it will now play nicely with phones! Keep an eye on the DelphiDabbler Blog for news.

These classes are designed to assist in various I/O related tasks. Classes are provided to:

  • Simplify the opening of files in various different modes with specified security attributes and to provide access to the file handle.
  • Simplify working with un-named pipes.
  • Handle the formatting of data read from pipes, for example reading Unicode strings.

These classes used to be included in the Console Application Runner Classes project to help handle standard I/O redirection but were pulled out into their own project because they have wider uses.


The classes require Delphi 7 and later.

They are also compatible with Windows 64 bit compilers of Delphi XE2 and later. The classes have Windows dependencies and so cannot be compiled for non-Windows targets.

The units can be included in both FireMonkey or VCL Windows applications.


The source code for these classes is documented using XML Documentation. In later version of Delphi this documentation will be displayed when the cursor is hovered over relevant class and method etc. names.

The classes are also fully documented online.

I'm afraid I have very limited time available to support the code library, and can't guarantee I'll find time for personalised advice.
