You'll need to ensure the application can handle that situation. If you add a "Background Color" property today, none of the settings files from before today will have access to it. One thing to keep in mind is that you would have to account for older settings instances in your application. When deserializing, use a Factory to retrieve the correct version of the settings class. When serializing, make sure to include the settings class version number. In a file, two entries 1- version 2- serialized settings data.
In a DB, two fields: 1- version 2- serialized settings data.
INSTALLBUILDER PARAMETERS PERSIST UPDATE
Add your new properties and update the version number. My initial thought is to include a version number when persisting.Įach time you update the settings class, create a new settings class that inherits from the last version. From time to time, you may add additional properties. You can find a detailed explanation of all the available parameters as well as how they are represented in the Available Parameters section. Store user specific settings for your application in a file or in a databaseĢ. Whether or not to show or not the page to the end user (it can still be set through the command line interface). You can use any of the options accepted by the installer, for example: installer-languagees prefix/home/bitrock/demo-1. The option file should contain one line per option, using the format keyvalue. See How-To (Object Class => Binary Serialization => To Memory => Encrypt => Save to File) at Referenceġ. Default value, in case one is not specified by the user. The 'optionfile' option is present on any installer created by InstallBuilder. This object can even be passed to other objects as arguments, and since it supports serialization, it is very flexible. This gives you strongly-typed settings, versioning, ability to add new settings, and even complex data types (other classes). Then the calling assembly just needs to create the object by calling a static/shared method. This ensures the implementation stays with the class.
INSTALLBUILDER PARAMETERS PERSIST HOW TO
Make sure this class knows how to serialize/deserialize itself because of your security requirement. This source code for the class can be reused in other assemblies, and persistence can be anywhere. The simpliest, effective and most flexible approach is to create a class, add settings, then serialize/deserialize when needed.
