Install Info

The Environment Variables unit, its help files and documentation are supplied in a zip file. Before installing you need to extract all the files from the zip file. The following files will be extracted:

  • PJEnvVars.pas – Routines and component source code.
  • PJEnvVars.dcr – Component palette glyph.
  • PJEnvVars.hlp – Help file that integrates with the Delphi 4 to 7 IDE.
  • PJEnvVars.als – Keyword file required when integrating the help file with Delphi 6 and 7.
  • ReadMe.htm – This read-me file.
  • DemoCode.htm – Examples of how to use the Environment Variables Unit.
  • ChangeLog.txt – Change log.
  • MPL.txt – Mozilla Public License.
  • Wiki.URL – Shortcut to online component Wiki.

You can now install the component into the Delphi IDE. To do this, the files PJEnvVars.pas and PJEnvVars.dcr should be added to a design time package. If you need help doing this see here.

Should you just want to use the routines, or create the component dynamically at run time you don't need to install the unit into the IDE and can simply either places it somewhere on your library path or include it in your projects.

Note that the help file included in the download can only integrate with the IDE in Delphi 4-7. For information on how to do this, see this article. Users of other versions of Delphi can either use the help file as a stand-alone file (in which case some links won't work) or you can use the Environment Variables Unit Wiki that can be accessed via the provided Wiki shortcut.
