Empty User.Config File Causes Exception?
Sep 13, 2007
Somehow the User.Config file was corrupted for an instance of my VB .NET app. When access one of my user level config property (My.Settings.MyProp) I get the a ConfigurationErrorsException with the message "Configuration system failed to initialize." I looked at the User.Config file and found that it is empty, it can be opened but there is no XML text contained within.I would like to programmatically fix the file if an exception is seen. When I attempt to use any of my user level properties, I continue to get the same exception. I've tried calling the Reset() but that yeilds the same exception. I then tried Save() to see if it would write out a default version, but it appears to do nothing (the file is not updated). My.Settings appears to be useless at this point.How can I reinitialize the User.Config file to the default config settings without deleting the old file? I would think that there should be some mechanism for restoring this file back to its default. And how can I update/reinitialize the My.Settings instance so that I can access the properties normally?

I'm looking for a way to specify the location for the User.config file that is used for storing the My.Settings object. It appears that this is not possible. The problem for me is, I don't want to be responsible for creating several different files on the users computer that really have no use and are difficult to find and clean once an update is released. For most users, this is not a serious problem, as many will probably never update the software, and most will probably only go through a couple of updates. On my system, there are config files for every build of the application, and the same to a lesser extent will be true for my beta testers.
I can understand that MS wants to make sure that no two applications will use the same location for storing application data, but a simple [UserData] [CompanyName][ApplicationName] for storing application data will probably suffice for 99.9999 percent of the legitimate applications in the world. Bogging a user's system down with erroneous files, no matter how small, is an unnecessary drain on system resources and a potential source of problems for the user. It's bad enough that most programs leave bits and pieces of themselves all over a user's system after De-installation - this to me seems only to exaggerate this problem.
Is the only way to get around this problem to write a whole new Settings Class? Is there a way to change the location of the UserConfig file to a more friendly (and more predictable) location that I am not finding for myself? It would seem that having at least the OPTION to specify a location for the User.Config file would be OBVIOUS and easy to implement, so why did they leave this out?

Is there equivalent for getevn/setenv functions in VB.NET. I have looked at system.Environment.GetEnvironmentVariable but it gives the system environment variables like USERNAME, COMPUTERNAME etc. I need to get the variables that are stored in config.user file. Is there any way to do that in VB>NET.

I made a project in VB.NET 2008. When I update my project I change the assembly version but the problem is that when the user gets the new version they lose their user settings.[code]Note the version number in the path. Is there any way save in a location not affected by changing the version?

I have a program that runs fine in the debugger. I started on the project in x86 mode this January and I've always been able to run it outside of the debugger, but this is the first time I've seen this error.The error says "ConfigurationErrorException was unhandled: Configuration system failed to initialize."The InnerException of the error said that the error was in the user.config file, and it gave me the directory of the user.config file that it was using. So I clicked synchronize in the project settings thinking that it would overwrite the current user.config file and that would probably fix the error. When it showed the confirmation dialog that it would delete the user.config file, I noticed that it had "vshost" in the directory.

After reading through a bunch of stuff, I was curious what production developers use for config files. I know that there is an app.config file that can be modified by the user of the program w/ settings. I also know I can create my own .xml file or .ini file to store settings as well. I wanted to know from the production side, what do you use and why?

I am just not happy with the fact that the user.config file gtets saved in the user's account folder. Is there a way to save it in the Application's Startup Folder instead? I couldn't find any configuration properties within the PROJECT PROPERTIES which would let me change the file location.

I know that when using my.settings that when I exit my app that it saves them and then next reload it imports my.settings back.
My question, is there a way to create this user.config file on the apps first load?

Don't know if this is possible, but I'd like a config section to be generated when another developer adds my dll to their project. This way they don't have to look up in code or a doc as to what they need to put in their config file.

Every time I compile my app and the version number changes (I have an auto-incrementing build number), I lose the user-configured app.config settings, since they're stored in the AppData folder for a specific version. Essentially, every release of my application starts from scratch as far as user settings go.
While this is a mild annoyance in development, it raises the question as I approach deployment/release - if I use the app.config to store my user settings, will the user's personalized settings be hosed every time they install a patch that changes the version number of my app? If so, is there an easy way to "upgrade" the settings from the previous release? I know that using HKCU in the registry is another option, but I like the ease of the My.Settings namespace, and I'd like to stay with app.config.

I've just started using user settings. This works ok however I'm having problems with the location of user.config.
When I run the project in Studio, user.config seems to be stored in a different place than when I build the project.
In fact every time I build it the location seems to change - users therefore lose their settings every time the project is built, which seems pretty useless.
The GUID & Assembly names etc do not change.

the My.Settings data is saved in the AppDataLocal folder for a user based on company.Then, inside the company folder there will be a folder for any applications published by that company, which contain the user.config file for that program.
C:Documents and SettingsRobert BurkeLocal SettingsApplication DataSerysoftSysPad.exe_Url_qr40iotmbi1lvvl4b5lecnfpoqogr5uw
The thing is, the folder for each program has a string of random alphanumeric characters at the end. I noticed that on both my XP and Win7 machine, the string is the same. What I am wanting to do is save the user.config file, but the only way to do this, seemingly, would be to hardcode that folder into the path to get the user.config file from.
how that string is generated, and what may possibly cause it to change in other releases even though, so far, it has stayed the same for several of my releases. I don't want to release a version one day and the string change and then it break my program.

Not sure if this has been asked before (couldn't find an answer), but is there a way to reuse a user.config file from a previous version of the application? For example a user.config file is stored in:
C:UsersJohnnyAppDataLocalCompanyApplicationName.exe_Url_wxcnyrmstqy3oj1qwckdjq3gjqkq4fel1.0.0.0user.config After a new version is installed it gets stored in:
C:UsersJohnnyAppDataLocalCompanyApplicationName.exe_Url_wglmejvw01nagu5t1y5yl12chynjomny1.0.0.1user.config The user then has to enter all settings again, even if the new version does not save more settings. An other problem is that although the user.config file is very small, it does get messy after a while when newer versions of the application get installed. Is there a way to clean up the unused user.config files and their folders?
It's the same problem with System.Windows.Forms.Application.LocalUserAppDataPath, that I'd like to use to save other files (containing Listview data), which points to:
C:UsersJohnnyAppDataLocalCompanyApplication1.0.0.0 The Listview data and other files created by the app can't be used anymore.This can be solved by getting the user's appdata folder with Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) and creating a new folder there with the name of the application. But this means there's one folder where the application is installed (user can choose this folder in the installer), one folder to save my own files to and one folder where VB stores the user.config file.
Can something be done about this "mess" or is this just something I have to live with?

I would like to commit the data put in a checkedlistbox to the user.config. I have found a way to commit them to my.settings but no matter what Save() method I call, it does not commit the new data (that is not bound to a control, through the propertybindings) to the user.config, either immediately or when I shutdown the application. Which means, when I loop through the settings when the application starts back up, the data is not there to be added back to the checkedlistbox. I have put save methods in the formclosing events as well as when the data is created in the my.settings. using my.mysettings, my.settings and my.settings.default. Thank you in advance for your input.
This first method is a called when a button is pushed. it checks the text and then calls the next method (AddProperty) which should add the property to my.settings and save it to user.config, but my understanding is that it is not written to the file till the applicatoin closes.

I am working on a program where some application config info is stored in a Userconfig.xml file. I am loading the file as an XMLDataProvider in the XAML via relative URI:
<XmlDataProvider x:Name="UserConfigDataSource" x:Key="UserConfigDataSource" Source="UserConfig.xml" d:IsDataSource="True"/>
I have a number of items throughout bound to elements in the document and an event handler that saves to the XMLDataProvider:
Private Sub SaveConfig(ByVal sender as Object, ByVal e as System.EventArgs)
'TODO: Add event handler implementation here
Dim SavePath As String = UserConfigDataSource.Source.LocalPath.ToString
[Code]....
When this executes I get the error "This operation is not supported for a relative URI". Is there a good way to produce an absolute URI (aside from getting the assembly executing location and trimming the executable filename from the end)? I expected this to be a somewhat simple procedure.

I'm building a live search inside our web application. But now i have a problem with a Web User Control where i can`t find a solution for.
I`m creating a User Control Search which later will be used for a default live search. Now i have created the solution inside a ASPX page without a user control. This works fine. But when i replace the code into a ASCX file (User Control) the input inside the textfield could not be found. No exception but the input of the function is nothing.
how to get the controlparameter or formparamter to work inside a user control? I already have tried things like ClientID this results into a exception (control not found). The fieldname with the $ instead of the _, this results into the input is nothing.

I am trying to prevent the User from proceeding if a specific text box is empty. All of the following lines of code SEEM TO work:
If txtTitle.text = "" Then.....
If txtTitle.Text = Nothing Then.....
If txtTitle.text = Nothing Then.....
(followed by a message box advising of the need for input)
The problem is, if the User enters a space (either accidentally or intentionally) all three of the above recognize the space as a valid entry.

I have an application where I have different picture boxes which the user can drag and move.I also have different empty pictureboxes.
What I want to do:I want to let the user be able to drag a picturebox to one of the empty pictureboxes. Also, If the user drags a picturebox to an invalid place (outside the bounds of any of the empty pictureboxes), the dragged picture box should return to its previous location.
So what I currently have is the usual drag-drop code and on the MouseUp event, I run this code (currently only checking for one empty picturebox):
If Not pbEmpty1.Bounds.Contains(Me.PointToClient(pbRemote.Location)) Then
pbRemote.Location = OldLocation
End If
(pbEmpty1 = Empty picturebox, pbRemote = picturebox that is dragged)
But it doesn't work, it doesn't care if the picturebox is inside the bounds of the empty picturebox or not, it still returns to its previous location...

I have this pretty simple application, it uses a webService to transfer data to my servers DataBase. Now it is very important for me to keep this application as one single file, and not having some XML files needed for it to work, but this is the case. I think the XML file holds the information to this webService, so without it the application crashes. Is there a way to get the application to work without this XML file, or a way to put the XML inside the exe archive?
