Way To Use A Dictionary Or Xml In The Application Settings?

Apr 18, 2010

I have to store a complex type in the application settings. I thought that storing it as XML would work best.he problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its valueIs there a way to use XDocument or XML in application settings?UpdateI found a way, simply by editing the .settings file with the xml editor.I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value).

WPF Key Value Pair Dictionary In Application Settings?

Jun 27, 2009

I am looking for a way to store a key-value pair in the application settings. From what I have found, key-value pair dictionaries are not serializable, and therefore cannot be stored in the application settings.Currently I have tried all sorts of dictionaries and collections and all of them work, until I restart the application, then all the settings are gone.

Asp.net - Use A Dictionary-like Collection As An Application Settings Object?

Jun 8, 2009

I'd like to store a set of key/value pairs in the application settings of my ASP.NET web app, but I'm not finding a straightforward way to do that. For example, these two questions tell me that StringDictionary etc. won't serialize to XML and suggest that I'll have to roll my own implementation. But it seems like this should be easier to do; after all, web.config is XML and < applicationSettings> is essentially a collection of key/value pairs, so it feels like I'm missing something obvious. Given my specific case below, do I really have to roll my own serialization, or is there an easier workaround?

The web app in question is a basic contact form that sends email to different recipients based on the value of a parameter; e.g. [URL]...The goal is to be able add or remove recipients (or change their addresses) by editing the web.config file so that I don't have to recompile and can easily maintain different configurations in test and production environments. For example:

// I can use something like this for the sender address SmtpMsg.From = New MailAddress(My.Settings.EmailSender)

// And then just edit this part of web.config to use different addresses in different environments.
<setting name="EmailSender" serializeAs="String"> <value>webcontact@exampledomain.com</value>

Application.Settings VB 2005 - Save Arrays Using The Settings System Object

Jan 14, 2009

I just wondered if you can or can't save arrays using the settings system object. There seems to be no way of entering it at designtime. It seems implied you cannot create new user settings.subobjects at runtime. I'm looking to find the easiest way to save a populated array of PictureBox's. If the only way is a self/custom made/managed .ini file then I need to know so i can start on that but I was hoping to use some of all this phaff in the new frameworks usefully.

Save A Collection Of Key/value Settings In My Application's "user Settings"?

Apr 14, 2008

I'm trying to save a collection of key/value settings in my application's "user settings" (they're column widths), but while I see no errors, when I run the code (in the IDE) my collection in "My.Settings" is always nothing at startup. I do a "My.Settings.Save" when the application exits, and barring the "serializers not found" errors in the IDE, no other errors occur. When I run my application as an exe, it behaves the same way..

Use Linq ToDictionary To Return A Dictionary With Multiple Values In The Dictionary Items?

Jan 25, 2010

I want to group items from a linq query under a header, so that for each header I have a list of objects that match the header title. I assumed the solution would be to use ToDictionary to convert the objects, but this allows only one object per "group" (or dictionary key). I assumed I could create the dictionary of type (String, List Of()), but I can't figure out how to write it. As an example I have written a simplified version below.

C# - Load A Dictionary Into A Console Application From An App.config?

I want to load a dictionary at startup in my console app from my app.config. I know that I could use an xml library or linq to XML to load it to parse and traverse it. My question is there a BUILT IN way of doing it. Isn't there some way to add an application configuration section into the app.config and then have it loaded automagically using ConfigurationManager class in the System.Configuration namespace?

Flatten A Dictionary Of Dictionaries And Sum The Values Of The Inner Dictionary With LINQ?

Apr 16, 2012

I have the following object:

countDictionary As Dictionary(of Category, Dictionary(of Date, Integer))

The Class has a Enumeration Property. For the purposes of demonstration, I'll call it MasterCategory.I have been trying to get out an object that looks like the following:

groupedCountDictionary As Dictionary(of MasterCategory, Dictionary(of Date, Integer)

The best result I could get was:

Lookup(of MasterCategory, Dictionary(of Date, Integer))

From:

countDictionary.ToLookup(Function(o) o.Key.MasterCategory, Function(o) o.Value)

Which results in a IEnumerable (Of Dictionary(of Date, Integer)) for each MasterCategory value.However, I need that IEnumerable of Dictionary flattened to one dictionary with all the integers summed (total counts) for each date. I then tried to use various selects and group bys (from numerous stackoverflow posts) to "flatten" it, but my efforts have fallen short.

Current Code

[Category Class]
- MasterCategory As Enum
- Name As String etc

.net - Application Settings Scope - User Vs Application?

Apr 13, 2012

If I create a user level application setting and bind it to a text box on a form, then type something in the textbox, the value is automatically saved and when the application is launched again the value appears in the textbox. This doesn't happen when I scope the setting as application.

Why are application scoped settings not saved automatically like user scoped settings are?

If this is by design, how can I manually save these settings and load them at runtime?

Application Settings (Specifying The Folder)?

Jul 22, 2011

Im using vb 2010 Express. I use 'Application settings' to store "demo version exp. date" of my program. My program stores the settings in "C:UserslenovoAppDataLocalMicrosoftWindowsApplication1.exe_Url_fbujq51flndh1ui4t4442ohpvlebhwej" folder.But when user copies the exe program and pastes it to another folder, the settings folder changes. I mean when user copies and pastes the exe program to another folder, the program starts to store the the settings in

"C:UserslenovoAppDataLocalMicrosoftWindowsApplication1.exe_Url_zywjz0o2tyrcmd35h5j1fdq0lplbklwc"

(Different than the first address). This causes the exp date to change everytime user copy-pasts the program.. Is there any way to specify where to store the settings? I mean when the program starts i want to store the settings always in "C:UserslenovoAppDataLocalMicrosoftxxxx" folder.

C# - Commit Application Settings Changes?

Nov 16, 2010

I'm binding user settings to a bunch of controls on a WinForm dialog that has OK/Cancel buttons. While this works great to read in the bindings in, I would only like to commit binding changes if a user clicks OK, and not if they click cancel. Is there a simplistic setting to achieve this rather than managing all reading and committing myself?

Right now, let's say I have a textbox that binds to a user setting called "country". It has "United States" in it and if a user changes it to "Bolivia", that will get committed as soon as it is typed instead of when the OK button is pressed.

To start with, I know that applications scope settings are read only, and user scope settings are read/write. My problem is this: I am creating an application which will be used in a setting where an "administrative" user (admin in this case does not denote any computer ability whatsoever- just the one in control of the computer) will be installing my application onto a computer where several users will likely use the application. I have a number of program settings which I would like the administrative user to be able to set, and have those settings be used for all users who run the program.

Using New My.settings After Application Restart

Apr 13, 2010

I'm using my.settings to store different communication parameters. After changing parameters, for several reasons, it's easier to restart the application then to re-initialize all objects/variables/etc using program code.

When I change my.settings and use save to save them. When I quit the application and manually start it again, the newly saved settings are used.

When I use either .restart, or application.exit in combination with process.start. The application will use the old values for my.settings.

If I read up on .restart there's a remark mentioning that it will restart the application using the initially used settings.

Before restarting the application, I manually checked if the new settings were really save to the user.config file, and they were.

My question: Is there a way to restart the application using either .restart, or application.exit in combination with process.start which will use the newly saved my.settings values?
