Creating a SETUP.DLL to Customize Setup
You need to develop a SETUP.DLL file to perform custom operations when you install
or remove custom applications on the 5020. The SETUP.DLL file should export the
following functions, which are fully documented in the Windows CE Programmer’s
Guide (ISBN 1-57231-643-8).
Install_Init
This function is called before installation begins. You can use Install_Init
to check the application version in a reinstall scenario and to determine if a dependent
application is present.
Install_Exit
This function is called after installation is completed. You can use
Install_Exit to handle errors that occurred during installation.
Uninstall_Init
This function is called before the uninstall begins. You can use
Uninstall_Init to close the application if it is running.
Uninstall_Exit
This function is called after the uninstall completes. You can use
Uninstall_Exit to save database data into a file, delete the database, and tell the user
where the data files are stored and how to reinstall the application.
