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.
View 2 RepliesI 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).
View 2 RepliesI'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>

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.

View 7 RepliesI 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.

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?

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.

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?
The following code checks each sentence in the listbox and if certain conditions are matched it add a piece of data to the list new question. Each input from the user is checked against each sentance in the listbox and if a match is found (based on the conditions) only then the data is added to the list and the loop exits. My problem now is that for each itteration cycle In_dep_token_pair.Key and trigger_dependency_token_pair can not be Subject and DirectObject at the same time. Is there any way to test for the next item in the keyvaluepair within the same itteration cycle? Something like trigger_dependency_token_pair(current item).Key = "Subject" and trigger_dependency_token_pair.key = "DirectObject".
If (Input_pair.Key = predicate) And (In_dep_token_pair.Key = "Subject" And trigger_dependency_token_pair.Key = "Subject") And _
(In_dep_token_pair.Value = trigger_dependency_token_pair.Value) Then

I have created a Dictionary class (MyDictionary for the example). I am currently trying to pass MyDictionary into a function, filter it into a new instance of MyDictionary and pass this new instance into another method.

Normally when I populate a combobox I do so by binding it to a datatable and assigning a display member and value member. I would like to do the same thing by adding pairs of items in code.I tried using a key-value pair, but that didn't work. The combobox displayed both the key and the value. I would like to have it just display one of the values and leave the other one invisible to the user, but available to me as a key.I thought about creating a custom class with two properties - one to use as the display member and the other to use as the value member. But before I re-invent the wheel I thought I'd check to see if there's already something there in the framework that I'm missing.

I'm using VB.Net's RijndaelManaged (RM) to encrypt files, using the RM.GenerateKey and RM.GenerateIV methods to generate the Key and IV and encrypting the file using the CryptoStream class. I'm planning on saving this Key and IV to a file and want to make sure I'm doing it the right way. I am combining the IV+Key, and encrypting that with my RSA Public key and writing it out to a file. Then, to decrypt I use the RSA Private key on this file to get the IV+Key, split them up and set RM.Key and RM.IV to these values and run the decryptor.
Is this the best method to accomplish this, or is there a preferred method for saving the IV & Key?
I have lots of TV Shows on my Hard Disk and every week I update that HD with the new episodes that have aired (I also download the .srt - subtitles - files) .
To do this, i have to take each pair of file (the .mp4 and .srt files) and put them in the HD folder (Ex: E:Tv ShowsDr HouseSeason 8). I have to do this lots of times and I waste several time to do this..
So, I was thinking, why not making a VS application to do this job?
I select all my .mp4 and .srt files from the week (witch are contained in a folder) and i drag them into my application witch should check the names of the files (they both have the same nome, Ex: House.S01E01.mp4 and House.S01E01.srt) and, by the first name ("House") search a hard drive witch I choose, and move my selected files to the "House" folder (where I have all the seasons of the Tv Show).
I'm trying to modify an app.config file that is not part of my .net application.My key needs to be unique and appear under a static key (Server1 or Server2) as the other application reads these values line by line, associating the database(n) value with the server(n) value.I cannot see a method of using the standard app.config methods against an external .config file, so I'm using the Xml Document class.[code]But cannot find a method of retriving the Key to check if it exists and more importantly increment the value?
