About the Unit
Introduction
This unit provides a static class for reading and modifying the environment variables available to the current process, along with a class that can be used to enumerate environment variable names.
The unit also contains a component and a set of routines that duplicate some of the features provided by the static class. These are now deprecated and are provided for backward compatibility reasons only: they should no longer be used in new code.
Compatibility
The Environment Variables Unit has been tested on all Delphi versions from 7 to XE4, excluding Delphi 2005. The unit is thought to be compilable with versions of Delphi back to version 4, but this has not been tested.
The unit is compatible with both the Windows 32- and 64-bit Delphi compilers and the VCL and FireMonkey frameworks (tested with FireMonkey 2 only).
.NET and non-Windows platforms are not supported.
Documentation
The Environment Variables Unit has comprehensive online documentation.
In addition, the unit is well documented with comments in XMLDoc format.
Demo Programs
Two different demo programs are included in the Demos\1 and
Demos\2 sub-directories. There are VCL and FireMonkey 2 versions
of each demo.
The demo programs are documented in the file DemosReadMe.htm that
can be found in the Demos directory.
How it works
This unit uses ideas from my article "How to access environment variables". The article shows how to develop routines similar to some of those in this unit and discusses their operation.
