For Delphi 2, 3, 4
Do you write Delphi applications for use within your
organization? Are all your users on the (Windows) network?
Are you tired of sending out new distributions every time
you make a change to the application's executable?
AutoUpdate adds code to your Delphi project and creates a
small subsidiary program to automatically transfer newer
versions of your applications' executables to your users.
REQUIREMENTS:
A Windows network (as opposed to Novell...but since I don't
have a Novell network I can't swear it won't work on one.)
A shared directory accessible by the users of your application.
LIMITATIONS:
Only the executable file of your application will be available
for new distribution. Any changes you may make to DLLs,
Tables, OCXs, or anything else external to the main executable
file will have to be distributed in the normal way.
USE:
1) BACK UP YOUR PROJECT FILE (.dpr). Nothing bad should
happen, but I make NO guarantees of any kind.
2) Start AutoUpdate (updater.exe)
3) Find the project you want to modify using the folder button
at the right of the "Project" field.
4) Find the network share point you will be using to store the
updated applications. This location must be accessible by
your users. Press the button to the right of the "Path to
Network files" field.
The path will be returned as a UNC path, if possible. It
is MUCH better to use UNC paths than Drive:Directory static
mappings. Users won't need permanent drive mappings this
way. In fact, they won't even need to know where the
programs reside.
5) Enter a name for the small subsidiary update program that
will be created. The default name is "Update", but you
can call it anything you'd like...except the same name as
the application you're modifying, of course.
I usually call mine "GetNewXXX", where XXX is the app name.
This allows me to have a central location for all updates
and new versions of the update sub-program.
6) You may check either or both of the compile options. If
checked, the files will be compiled using DCC32.EXE, the
command-line compiler. DCC32 will use a file called
DCC32.CFG for the compile options, if one is present. See
the Delphi Help files for more information on these options.
7) Press the "Do It!" button. If all goes well, a message will
pop up telling you the status, and whether you need to
recompile your application, or compile the newly created
Update program.
8) Include the Update program with the initial distribution of
your application, and place it in the same directory as the
application.
9) Put any updates to your application in the shared network
directory. When your users start the application, they will
be asked whether they want the newer version. If they do,
the new version will be copied and started.
New versions of the Update program will also be copied
automatically.
If you change the location of the shared directory, leave a
copy of the NEW application and the NEW Update program in
the old one until all your users have gotten the update.
This is necessary because the process uses file dates to
determine whether a new version is available. A dummy
application with an advanced date will also work...the new
version will be copied from the new directory.
WARNING:
If you change, rearrange, or otherwise modify the code and {*} symbols
AutoUpdate put in the .dpr, the next time you run AutoUpdate against
that application, you may end up with duplicate lines of code. This
warning also applies to the first line in the .dpr which starts with
"(* Lines beginning with {*}" This line is an indicator to AutoUpdate
that it should replace existing code, rather than insert new code.
PRICE:
If you like this little utility...two samples of your country's paper
currency would be appreciated. In good condition, suitable for placing
in a display case (front and back, which is why I'd need two).
The denomination of the bills is up to you.
Acceptable alternatives: A cool app or component you wrote, interesting
pix, midi files, mpegs, something touristy from your country...
