This is the home page for a "DFF Library" sub-web which
contains a number of non-visual units which are used in many programs on the
site.
Download Current Library (DFFLibV15
)
Motivation
The library came into existence because these units are used
in multiple programs posted here on the DelphiForFun website. Although the
units are quite stable, once in a while some correction or enhancement
occurs. When that happens, I was faced with the problem of adding to
the changed unit to the zipped source code file of each program that uses that
unit and re-uploading the file. And that meant lots of manual
effort in finding and updating them all and the inevitable existence of multiple
versions of the same unit.
Mechanics of applying Library to my (your) local system
Under the new system, the source for each "Library"
unit is kept in a single folder, (named "DFF_Library" on my system at
home)
and the folder was added to the list of Libraries searched by Delphi when
compiling programs. Below is a description of how to accomplish this.
(Alternatively, you can add the unzip the DFF library file to your
Borland\Delphi\Lib folder which is always searched by Delphi.)
Extending Delphi's library search list
From Delphi's main menu, click "Tools", then
"Environment Options", then "Library". Clicking the
button on the Libraries line will open a dialog where you can select and add your
new library to the list of Libraries searched by Delphi when looking for a unit
referenced by a program been compiled.
Mechanics of Downloading
The entire library of unit has been collected in to single
zipped file that may be downloaded here.
The download page will identify the current library version and redirect you to
that file. This is so that I do not have to update all library download
links each time a new version is posted.
The original "demo" programs showing the capabilities of each
unit are being relocated from other places on DFF to this sub-web.
The zipped source code file for those programs, as well as any others that use
the library units will not contain them. Instead,
a separate link to download the latest Library will be included on each page
that uses any unit from the library. These changes will be
implemented over time as programs using library units are updated. In general, if you see a
link to the Library zip file in the download links section of any page, you will
need to download the library, if you have not already done so. If you do not see a
link there, either the program does not use a library unit, or it does,
but I haven't updated that page yet. At least that's the plan.
