Where to store configuration data

Lost User

When writing a MFC app (typically MDI type), how do people usually store the configuration options ? The samples I've looked at usually don't save them so you have to reset any option whe nyou restart the application. Preferred methods or any to avoid ? Thanks. Elaine :rose: The tigress is here :-D

One solution is the registry. Kuphryn

Registry is fine, but not the newest thing under the stars... For "partially trusted" applications (kind of the .NET sandbox), there's Isolated Storage. There was also a relatively quick way to serialize a class to an XML file in the Application Data of the current user - which might be the "modern" way. [edit] damn! I'm just back from the C# forum - for good old MFC it's the registry[/edit]

You could always go with the ultra-modern INI file! :)

XML files are the best for saving configuration data!

This allows data to be serialised to and from the registry, so I just create a class for the data that can be serialised - one entry that is defined purely within the class ! Serialising into the registry[^] Elaine :rose: The tigress is here :-D

After years of storing information in the registry, we are now standardizing on... ini files! The reason? MUCH lower support costs for our particular niche. My company sells to schools and our products are typically run in networked situations. School networks 1. Are run by sysadmins who have a poor understanding of their networks. 2. Are EXTREMELY concerned with locking down the system. 3. Often have some truly bizarre policies in place. 4. Often rebuild a standard working environment on every login. We have found that our customers like being able to edit, copy and move a straight-forward text file and they can usually solve their problems themselves. With our old registry-based solution we spent enormous amounts of time trying to make our system support their (often bizarre) needs and then explaining the solution to them.
