Attatch Application Settings To ComboBox Object
Feb 25, 2012
I'm pretty sure this has been answered on this thread before, but I'm having trouble searching for it, so I decided to make a new post. Anyway, My problem is that I have a Setting from "My.Settings.Navigation" that is a Specialized String Collection, and what I am trying to do is find a method in which I can attach "My.Settings.Navigation" to a ComboBox. I was also wondering if it was possible to make it only hold up to 20 items at a time?

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.

I have a custom settings file that I designed using the designer. In my form, I have a function that creates a new instance of this settings by using a dim statement. Then I add this new settings object to a hashtable. After I exit this function, I no longer have access to the settings object without using the hashtable to retrieve it. If I want to remove the object from the hashtable, I can do a simple remove but the settings object still exists somewhere in memory. How can I dispose of this object as well since it inherits from ApplicationSettingsBase and does not have a built in Dispose() function?

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>
[Code]...

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.

The issue is when I try to add a new item to the ArrayList with the following code, it gives me an error:
vb Private Sub btnLabelAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLabelAdd.Click
Dim result As String = InputBox("New Filter Label:", "Label List")
[CODE]................
Object reference not set to an instance of an object.
I'm not really sure what I'm supposed to be doing with this. It's a new setting I just added and it's empty, so I'm not sure if that has anything to do with it or not. Anyone know what's going on and what needs to be done to get it to accept a value and not want to be "initialized"?

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.

My problem is when i try to call Application.Run() in a application without a form i get "Object reference not set to an instance of an object." when i run it outside VS. but if ran in debug or release mode it works just fine. i may just be forgetting to setup application right, but ive done it before in this same manor and it worked fine.
Sub main() 'this runs first.
AddHandler Application.ApplicationExit, AddressOf ExitEventHandler
dbg_f("handle added")

Commented out init_timer and init_ready, and now it causes the same error for the myName line. there seems to be something wrong with class Application. btw theres seems to be something wrong with the forum code formatting.

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..

Not too familar with the propertygrid control.But I have two comboboxes that need to be added to it from my.settings. How do i setup both My.Settings and then link it into the propertygrid?
The dropdowns will be named "Location" with 5 values, and the second called Hourly/Salary with 2 values.
This would be part of my larger application where the user selects these values and then logs in.

My.Settings.Current_DB is bound to 'cbdatabase' which is a combobox which is filled by this method:
me.cbdatabase.datasource = (From foulder in New IO.DirectoryInfo("" & Application.StartUpPath & "Database").GetDirectories Select (folder.Name)).ToArray I am using the My.Settings.Current_DB to keep track of the current database being used by the client. So that throughout the program and when the program starts up it knows what the current database is.
The databases and the folders have the same name, in order to keep track of. My problem is when the combobox is filled when the program starts, it is overwriting the current info with the first item of the info loaded into the combo box.
[Code]...
Instead of maintaining the Current_DB as "Default", it updates it with the first item into the Combobox and that is "Alabama". How do I fix this so that it maintains the correct Current_DB and not update when the Combobox is filled.

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'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]

I am trying to save a custom object as a user setting in a VB.net app. This object consists of a List(Of Pair(Of String, Object)). Pair is a custom class which has two read/write properties (a String and an Object).
If I put simple types like int, string, datetime as the second value of my pair, the setting is saved without any problem. But if I try to put something more complex, like a list, there seems to be a problem during serialization and my setting is not saved.
String values in my pairs are serialized like this:
<value1>Priority_1</value1>
Object values are serialized with a special attribute:
<value2 xsi:type="xsd:int">2</value2>
Seems like values of type Object are serialized differently, to "remember" what is the real type of the object. Why can't it do the same for more complex types like List(Of T)?

I had added the items
1

3 to the combobox.
Then I gave the "Select" to the text of the combobox.
How can I able to reset combobox to select the text("Select").
I had tried by giving -1 to the SelectedIndex. But it gives only Empty.

I have a program that reads a database file(.csv or.Txt) then allows user to select data from 6 different comboxes and taext boxes are then populated based on the selection made from combobox
I would like to be able to give the user the option to save their settings so next time the program is open it will connect to the same database as the last connection and also have comboboxes go to the last selection Do I have to create a save setting value for each combobox? and the connection string?
is there a simple way to just save everything? so when the program is open it goes back to the last time it was open.

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?

I have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)

My VB.net application has a lot of application settings, is it possible to group them somehow(other than having a common name)?For example, my application has a lot of winforms each of which needs to save some information about itself. Is it possible to use something like:
Form1.width = My.Settings.Form1.Width
Form2.width = My.Settings.Form2.Width
etc.

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.

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.
