Store The Settings In A Text File Or Database?
Jan 2, 2010
I'm working on a project right now that basically prints a string to the field that has focus in internet explorer and there's quite a bit of user specified information that needs to load when the vb program loads. Should I use a text file to store and retrieve the settings or a database? I'm a new programmer and I don't really have a clear idea on when I should use a text file compared to a database or the registry to store info. Also, if I use a database like access 2007 for example, wouldn't an end user run into an exception if they don't have that software installed on their comp? Is there a universal database format? I've linked some screenshots of the prog if you want to get an idea of how much info I need to store.

I am storing my connection string in my app.config file. I am using sql server express 2005. The connection string on my dev machine is different from the ones at the clients. so each time I update I open the config file and edit the connection string setting. This is quite a pain.also I have now published my app to an ftp folder so that the clients can get the updates each time I make changes. saves me the hassle of going to them each time i update. so now i need it to be so that I won't have to change the setting all the time.Would the best way be to store the connection string in a settings table in the database?

I am using an .ini file to store my settings, so they are editable. But the thing is, it wont redirect? I had it working some minutes ago, but now, it just gives me a white page.. It didnt do that some minutes ago Here is my whole code, as it would take time to split it all that has with .Ini file to do.

Each year I have to create 1099s from a legacy system. So in the past I had Foxpro code that ran out of a directory near where the Foxpro dataware house was. In 2009 we moved to SQL so I have to convert the code to VB and SQL
But I need to still store the text files and the report and I wanted to save settings in this "working directory"

Does this seem like the propery way to do this?
Finding documentation on XML is really difficult, because there is so much yet all of the examples seem to do it a different way.

I store three items in My.Settings. One is a serialized string, and the other two are GUIDs. When the main form starts, those three items are loaded into various places. On rare, and so far unpredictable, occasions, one of these GUIDs is notably absent. The others may or may not be, I have yet to be able to check. Since it happens so infrequently (twice this month, though I have been working on the code every day), I'm having a very hard time tracking down the problem. However, it got me wondering where these values are stored. I see one of them showing up in App.Config, though without a value. Is there a place I can see the others?

switching our database over to UTF-8 (multi-byte char, unicode) encoding from IBM819 (single-byte char, Latin1 subset), because of a new requirement to support text entry of Czech characters.I've just been reminded by a colleague of the nchar and nvarchar column types, which neither of us has actually ever used.
If I were to define the relevant columns as nchar and nvarchar instead of char and varchar, what would I have to do to allow my currently-IBM819 database to work with this new IBM819-incompatible text coming in from my .net application?Would all conversion be automatic? Would I need to write some scary conversion code?
EDIT: Right, I defined an "nchartest" table containing a single column, "ntest" of type nchar(500).I connected to that via .net code and confirmed that 500 chars of lorem ipsum could be entered:
Dim insertString As String = "INSERT INTO nchartest VALUES (?)"
Dim insertCommand As New IfxCommand(insertString, cConnection, tTransaction)
insertCommand.Parameters.Add("incident_recno", IfxType.NChar).Value = "[lipsum]"
Return insertCommand.ExecuteNonQuery
I then replaced the lipsum string with 100 or so chars of Czech text, and attempting to insert that caused an IfxException to be thrown by the .net Informix interface, with the message ERROR [HY000] [Informix .NET provider]Unspecified System Error = -21005.
Following up on some research I did yesterday, I tried setting my CLIENT_LOCALE setting in my connection string to en_US to match that reported by Threading.Thread.CurrentThread.CurrentUICulture, but that connection could not be opened due to ERROR [HY000] [Informix .NET provider][Informix]Unable to load locale categories.
Following that, I tried setting CLIENT_LOCALE=en_US.unicode, which produced an ERROR [HY000] [Informix .NET provider][Informix]Unspecified System Error = -31142.

You know how using My.Settings.something to store persistent data is done only for user settings and not application settings. This information is stored in the registry on the local user section.My problem here is that even if it is in the same machine, when a user changes some setting it is not reflected on other users. This is desirable for some of them but there are a few I would like to keep for all users.Is there a way to do it with the settings? Do I need to write to the registry in the machine section? or do you just recomend I create a configuration file?

i need to store Application wide Settings in my Application like:
Connection to DB (Servername) Username/Password Registrar/Serial etc. I think there are basically two Options:
Store them in the Registry Store them in an Application Settings File Using one of the methods above is no problem, but under Windows 7 my Application running in normal user mode allows me only to store user specific data. For example inside UserAppDataRegistry, UserAppDataPath etc.
But when i want to use e.g. CommonAppDataRegistry to write my Data in, then i get no access to it, due to missing privileges.
Now my question:
Where and how to store Application Wide Data? How are others doing this? When i purchase an application and install it on my pc, it asks me for Uusername and Serial. When i insert it then it saves it somewhere without asking me for Administrative Privileges or something else.

I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were. To do so, when the program is closed I have the information stored in a .txt file. it looks something to the effect of:
name, type, votes
andy, bear, 0
bart, dog, 0
candy, cat, 0
hopsie, bunny, 0

I've written a windows service in VB.NET 2.0 and the service needs to know a few file paths and other settings when it starts in order to be able to do what its supposed to do. These are settings that users of my service need to be able to configure themselves so I cant hard code them in.At the moment I just have the service look for a file named Config.INI in the same directory that it is being run from and if this file exists it attempts to read the settings in from there... this works perfectly, but it just feels a bit clunky and old. If it was a normal windows app I would store the settings in an XML file in the user's application data folder or something but as this is a Service then thats not possible as it is not run by any one user (well technically it is, the Local System account). I then thought about using the registry but I seem to recall people saying that you should avoid storing settings in the registry if you can really, especially with the new security in Vista and Server 2008.

I'm wanting to store some settings for my program in an XML document. I've found plenty of places that allow you to write an XML document to somewhere on the hard drive although I'm wanting to link it in with the project so when the program installs it setups up the XML as well. This is also so when the program uninstalls it removes the XML.So I was wondering how I would go about writing to the XML document in my project, could it be done with Linq?
