TAutoUpdate is an Object Pascal Class created with the sole objective of easily adding Auto Update capability to Delphi/FreePascal applications.

Features

• Easy to implement (only one unit).
• Allows retrieval of updates from FTP servers.
• Allows retrieval of updates from HTTP servers.

Example

1) Create the file update.ini in the same folder as the main application.

2) Contents of update.ini [default] updatefile=/etc/updateinfo.ini method=ftp [params] host=myhost.com port=21 user=myusername pass=mypassword

This connects to the ftp server and looks for the file /etc/updateinfo.ini who tells TAutoUpdate where is the update zip file containing all the new files, then the file is unzipped and executes update.exe, the file in charge of upgrading the program.

3) Contents of updateinfo.ini:

[default] installer=install.zip

4) Execute TAutoUpdate to update your program:

with TAutoUpdate.Create('update.ini') do begin Execute; Free; end;

External libraries used

Abbrevia for unzip files.

Synapse for Http/Ftp downloading.
