Storing Strings And Application Settings?
Jun 25, 2010
I've came to the stage where i need to save strings and application settings for my application. The My.Settings have worked it out until now. Now i have to store so many settings it's hard to keep track of them. That is why i need something new. So i've been looking around in INI files which seems impressively simple - but not very flexible. I've also took a look at XML which seems to be something to dive in to. But what i need now is advice. How do you store settings?

I will need to store 3 tables of data. Instead of implementing an entire database backend, I just want to store the record for these tables in application.settings.I don't care about security. Is it advisable to do it with application settings? how else would you do it? Perhaps storing a matrix in application.settings would be OK?

I am trying to store an enum in my application settings. This enum is defined within my main assembly in the same namespace. When I try to find the type under the application settings, it seems like I can't find any types within my namespace. I can see all the types of the assemblies I reference though.

I'm creating a small tool for our team that performs backups of our servers. The plan is to put the tool in a central location so that anyone can use it.I'd like to store, somewhere, the date of the last backup for each server. I was wondering if I could use an application settings (with Application scope) for this? Is this bad practice? If so, what's the best practice? XML? text file? registry?

I am using VB 2008 & MS Access 2007 Databases for my Windows Forms Applications.The Problem is my Connection strings have been disappeared from DataSource Configuration Wizards & now i am unable to edit any Connection String in DataSet Designer.I had tried to create a Macro in MS Access Data File but didn't know how to create & so desided not to save any & just quit from Access and came back to Visual studio. Since then only this prob. has started. Earlier to this everything was just fine.I have tried to uninstall MS Office as well as Visual Studio then Re-installed Visual Studio but the problem is still there.
1] Error while trying to Reconfigure Data Adapter in Dataset
2] Disappeared options & Empty Connection Combo Box
3] Add Connection DialogBox with no DataSource property line in the Grid control

I am working on a .NET Windows Service where I am trying to store settings that will be used when the service is started and while it is running. I have searched through posts on SO and found that using the Settings in the properties of the project is great for use with console and winforms applications. However, Google and SO are silent when it pertains to storing these settings with a windows service.

We decided to use the registry for handling our deployment with connection strings in our VB.net application.
The requirements are:
If the program cannot connect to the server, first check the registry for a connection string. IF not, create the folder and fill in the name, type, and data. Make sure its encrypted.
I have never edited or created anything in the registry.

I recently had to use my "String converter" to convert 20 lines of text to a single line of "VB .Net String coding". For example:
This is line one
This is line two
This is line three "with extra stuff"
[Code]...
"This is line one" & vbCrLf & "This is line two" & vbCrLf & "This is line three " & chr(34) & "with extra stuff" & chr(34) & vbCrLf & vbCrLf & "Empty line above me"What is the best way to represent these types of Strings? For example, if you have to display a long message or just a label with information that changes.I was thinking of some sort of text file collection, but it is a little useless to have 100 text files of information of 5-6 lines.

I'm still doing upgrades on my program that i'm creating and i've run into a bump again. I'm currently using a multi-dimension array to store a name, email, password, email provider, and user name. These 5 values are stored, corresponding with the latter, meaning the array is build as: name 1....n user name 1....n user email 1....n user email provider 1....n password 1....n So my question is, how can i store this in My.Settings? To be clearer, i'll use code: My.Settings.Name = name My.Settings.UserName = userName etc..... My current set up for a first run is like so... My.Settings.Password = adminInfo(2, 0) My.Settings.UserName = admingInfo(1, 0) etc.

I have a VB2010 application that must run as multiple instances on the same PC (it is a controlling/monitoring program of several devices, each instance of the program control one device)
Of course, the same application must save its own setting in different place, one for each device. For example, if I start the application for the device 3, I have to save the setting in a place marked as "3", in this way, when I start the application for device 4 it will load the settings for device 4 and not 3.
Of course all labels and similar stuffs must refer the starting device: i.e. the mdi caption must report "device 4", and so on...
In vb6 I created a shortcut with a command line and made my application accepting command line parameters.
In this way I could start the application passing the device number too. For example "myapp.exe 3" start my application for the device 3.
I stored all settings in several INI file, each one for a device: setting1.ini, setting2.ini, setting3.ini, ....
I was wondering if in vb2010 would be a better way to do that.
1. How could I start multiple instances?
2. How could I store the settings?

When it comes to storing SQL in code, most people use strings:Dim strSql As String = "Select Foo, Bar From FooBarTable Where Something = @Something"The problem is, when you have very long SQL strings, reading them in code becomes difficult. You can usually split the strings up like this:
Dim strSql As String = "Select Foo, Bar From FooBarTable " & _
"Where Something = @Something"
This causes a number of problems:

I've always used this approach while implementing data layer DLL for web application:
1) put datasets into the dll project
2) use a helper class with a method like this:
public shared sub settCnnStr(strconnhere as string)
My.Settings.Item("connectionString") = strconnhere
end sub
3) when I need to use the dll I call a method like this (usually into global.asax):
xxxxxxx.helper.setCnnStr("yyyyyyyyyyyyyy")
This method always worked for me nicely but I'd like to know if this method could have serious drawback or if there's a better solution.

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.

Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.

i have created a user setting named 'setmeup' as string, scope = user, value = "magical meow meow!".in my code i access it and assign it a new value like this...my.settings.setmeup = "howdy cowboy!"my.settings.save()application.restart()when the application restarts, i expect the my.settings.setmeup = "howdy cowboy!" but when i check its contents its still "magical meow meow!".but when i use application.exit() instead of application.restart() and manually restart the program, my.settings.setmeup = "howdy cowboy!" which is correct.what must i do? i want to use application.restart() because i don't want the users to double-click the icon again to start the program. i want the program to restart automatically.

I am storing some user settings by the very handy My.Settings classes in VB.net and it seems to be taking a mixed case string (a file path and filename) and returns it in all upper case.

I was wondering if it's possible to store application data within an application without storing the data in an external file. For example, in my application, the user can choose where he/she would like to store the files that the application creates. I need to make the application remember the location that the user specified. I've tried using My.Settings to save this information, but since my application is standalone, if the location of the application changes, the My.Settings information changes as well (unless I coded it incorrectly before). I would prefer not to store this data in a .txt file or something similar.

I am trying to store things such as user data for each user in my program, like with a class I made named UserData. I would like to have data different for each user. How can I do this? Also, I need to be able to access other user's data from my account.I tried using Settings, but they only had a limited number of classes, and the settings didn't seem to save for some reason.

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..

I am at a new company and I am building a wizard for a web app, (.Net/4.0). The user goes to a few separate screens during the wizard process and must return to the original screen before completion of the wizard. This is different from how they normally do this. But this is how it is TO BE DONE.
One option is to store the result of each panel in the main screen in the DB. So then, when the user leaves & redirects back. I could check for a querystring then call a datareader and populate original values appropriately.

I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.
My XML file looks like this
<Data>
<Login>
<UserName> (UserName) </UserName>
<Password> (Password </Password>
</Login>
<Applications>

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

I have been tasked to create an application, for which the requirements may change over time.This application will be a data entry Windows application,of which multiple copies will be running.All data will be written to text (.CSV) files for validation before being uploaded to a remote mainframe system (iSeries).My application needs to store certain variable information in an external text (or XML) file; for example, the file path to shared resources (which may change over time),as well as the specific data fields required by the mainframe system.
My questionsare these: what is considered the best practice for accomplishing such a task, and how would I accomplish it?I am completely new to XML, so I don't even know where to begin, although I am sure that XML is the path to follow for what I am trying to accomplish.
