XML file vs. DLL?

I'd like feedback on using an app.config file to store static
information such as company name, database name, etc. then use a DLL to
load it. I want to put everything into enumerators. This is a winform
app. I'd like to avoid having to create an instance to access this
information. In other words, using only static methods.

The DLL allows me do any related additional processing specific to only
the static info. This seperates the static information from the
application and keeps it from attaching itself to one of the winforms
via instantiation. In other words, the winform app will use a non form
class as its startup object. The non form class will call the DLL, do
any additional processing, and load the first form. Does any one see
problems doing this?

XML or config file:
Will I need to load from the config file everytime since the methods
are static? Example?

Thanks,
Brett

Brett,

I would look into creating a configuration provider. Basically, you can
place your XML configuration in the .config file for the app, and then that
information would be provided through the classes in the
System.Configur ation namespace.

Check out this article on developer.com titled "Using Application
Configuration File in .NET", located at (watch for line wrap):

http://www.developer.com/net/net/article.php/3396111

This should give you the information you need to create your own
configuration handler.

Hope this helps.

Yes, and I was doing that before. However, as you can see in the
example, he must provide a hard coded string reference to keys in the
file. Now, if those keys change, he's stuck. That's why I want a
combination of the configuration provider and DLL. The DLL will load
the enumerators from the file. Then I'd like to statically access the
enumerators. This keeps the app from having to know anything about the
file except in the initial startup non form class.

I have compiled some code, some written by me, some compiled from various sources online, and basically i've got a very simple flat file photo gallery. An upload form, to upload the photos and give them a caption, storing the caption and filename in a text file. It's a bit buggy when removing the photos and captions from the file, and also in displaying them on the delete page. you can see it in action at www.4am.com.au/gallery/upload.php...

Hello, I created a script to upload a file. To determine the file type I am using userPostedFile.ContentType. For example, for a png image I get "image/png". My questions are: 1. Where can I find a list of all the types which can be returned? For example, if it is a Word document will it return "document/doc".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
