My.Settings.MyConnectionString Works But App.config Don't?
Oct 8, 2009
I'm not a WinForms developer, but have been doing ASP.NET for quite some time.I have to write something in VB.NET that just pushes some simple data to a database.So I created the VB.NET WinForms app (Visual Studio 2005).When I run the app it works fine for using:
Dim conMyData As SqlConnection
Dim cmdInsert As SqlCommand
Dim isSaved As Boolean
[code]....
That is, if I define the connection string inside of the properties of the project. If I build my project, snatch the .exe from the bindebug folder and run it on my desktop,it works ONLY if I have the version that says My.Settings.MyConnectionString Otherwise, if I use the other version where I am pulling the connection string from my app.config file it only works if I run the project through visual studio, it will not run by just opening up the .exe on my desktop. It syas something like ConnectionString not set, or sometimes it states object not set to an instance of something... why does it work from within the project?Is it because when I build the project it cannot reference that app.config file since I've moved it to my desktop?
I have a class library (Named ADI), that needs some configuration settings from the project using it (like connectionstring, filesystem locations etc).
I want to define these settings in my Windows Forms/Web Projects App.Config or Web.Config, like other settings.
Here is part of my app.config for my windows forms application:
I have created a settings-file for my plug-in-based app. When the mainApp writes the settings to the file, the pluginApp should read the settings from the settings-file (when opening or at runtime even better), but somehow it reads the settings from the app.config-file. This means that the pluginApp never will read the settings according the values of the file.
[Code] When I run this on my visual studio 2008 dev server it runs fine and works well. When I publish to IIS I always get Http 403 Forbidden Errors when trying to access any page on the site. There is 1 folder within my site that should be login protected called 'administration'.
A Windows service written in VB.NET is using the My.Settings namespace for simplicity. There are only three settings to read, and these are read within the constructor of the ServiceLauncher.
I am attempting to install the service as such:
installutil GID.ServiceLauncher.exe
And this is successful, however the config settings it is using are not the ones within the GID.ServiceLauncher.exe.config file, instead it is using the ones baked into the app as Default Settings within Settings.Designer.vb (marked with DefaultSettingValueAttribute). [The questionable wisdom of Microsoft not allowing a developer to ignore default settings is another question entirely].
How can I further diagnose this issue, and maybe force a reload of settings? I tried calling My.Settings.Default.Reload, however this did nothing. All settings are application settings, and only differ by "value" from those in the auto generated file.
I have successfully attached the debugger using System.Diagnostics.Debugger.Launch() and true enough, the settings are still the default settings.
In anticipation of the question, the background: The reason for requiring configuration settings is because this is a very straightforward service that simply executes an exe; and this exe is in configurable location. There are other reasons also, such as I wish to have the service name configurable without recompiling.
Private Sub SaveButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles SaveButton.Click Dim Config As Configuration Dim Section As ConnectionStringsSection
However, xmlFilePath shows up as Nothing after that line of code is run.
What's the correct code to get a setting out of the web.config file in an ASP.NET application?
NOTE: Although you can add keys individually to the <appsettings> tag, I'm trying to figure out how to use it with the "Settings" tab in the project's properties.
Say I have a Class Library project with its own .dll.config, and a forms application. I want to confirm that it is impossible to reference the .dll.config file from the .exe.config file and still use My.Settings.
For example: I have SomeClassLibrary project, with SomeSetting that I can access through My.Settings.SomeSetting. I also have SomeFormsApp project. This is what I want my SomeFormsApp.exe.config to look like:
From my readings, this seems impossible. I either need to copy the content of SomeClassLibrary.dll.config into SomeFormsApp.exe.config, which is tedious and error prone when copying from multiple class libraries, or I need to use ConfigurationManager, which bypasses My.Settings and its typed, Intellisensed goodness.
(My question is similar to this one, but the code is slightly different, and the solution doesn't work for me)I'm trying to save settings changes to the app.config:
Dim config As System.Configuration.Configuration = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) config.AppSettings.Settings("HistoryRootDirectoryPath").Value = p_historySavingPath
I have been searching and posting regarding this problem and have found nothing to aid me. Discussion is either on web.config files or deal only with external files for connection strings or earlier versions of vb.net not 2008.I have already successfully put connection strings into an external config file, but trying the same approach with application settings has failed.There are two sections of the app.config involved with application settings.
1. the configuration and config sections at the top of the config. file where the section group and the section name are described.
2. the actually data for the application settings by section group section name which appears in the body of the configuraton section of the app.config.[code]
I would like to tweak some of the numbers in the app.exe.config file while the program is running. I would like my program to re-load those valued from the edited txt file.
I have tried my.settings.reset, reload, and upgrade. None of these seem to reload the values from the config file into the program
vs 2005 vb.net
How can i get my program to re-read the config file into its memory once it is up and running. say when a button is clicked?
I am writing an application that will be used to extract information from any one of three different database applications, depending on the option selected. I would also like it to be possible to run it against one of several environments (e.g. development, test or live).
I plan to hold the relevant logon details (in encrypted form, of course) in the app.config file, with the appropriate details selected depending on the environment and application. Rather than have each option hard-coded into a Select Case statement, I want to be able to nest the variables in the app.config. I had envisaged a section of the config file looking like this:
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?
Is there a simple way to read from the global application.exe.config file from a dll?urrently I am loading the file as an XmlDocument but I wonder if there is a better solution.That's what I mean:If I create a new WinForms Project I have a Settings Tab in the Project properties where I can add some simple values (And I want to access the per Application settings, not the user beased ones).From my code I can access these values with:
The Settings class is autogenerated in the file Settings.Designer.cs.Now I have the case where a dll need's to read the settings from the Main Application's config file. Is there a simple way to achive this? Currently I am reading the file as an XML Document.
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.
Is there a really simple way to save the app.config file to a location then load it again? I'm making a multiclient app. I was planning on having each user have a folder, and in that folder would be their personalized app.config file that would load when they log in. I don't really know any XML.
I am trying to create an msi install for my windows service. The reason for creating an msi is that the intended users want to be able to quickly install the service with as-little intervention as possible.
i can get the service to install as a msi but i have a variable within my code that i need the user to define when the msi is being installed. the variable i require from the user is the file path which they want the xml files my service creates to be located.
i thought i could configure the app.config application settings to contain the file path that the xml files should be written to. However i'm struggling to do this and im not to sure if its the best way to do it?
I have my setup project that contains my executable and has my textbox which will contain the one variable from the user.I have an installer class which contains my serviceinstaller and process installer. This is where im struggling to understand what i need to do next. Do i need to override the install method? The current code of my installer class was automatically generated and is as follows:
I recently changed application settings to be in an encrypted config file.The first time I run any application and try to retrieve a setting (My.settings. ...) from the config file I get an Unrecognized attribute 'configProtectionProvider'If I restart the application I don't get an error due to the fact that it doesn't re-encrypt during that run. Why when I run the application for the first time am I getting this error?
I am encrypting the config file on application startup using the following code:
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'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?
Our main application has both a asp.net and winforms component. There is a class that is used by both sides and needs info from either the web.config or app.config files. The class itself does not know if it's on the client side or on the web server (at this point). We are getting errors when it's attempting read app.config when it's on the web side. Is there a way for the class to tell if it needs to read web.config or app.config?
'insert link sheet1.Hyperlinks.Add(sheet1.Range("P1"), "http://http://www.vbforums.com", "") the code of the button (ribbon)

When I press the button, it connects to the web site. when the sheet1 is selected, it works, but when the sheet2 is selected, not works, why? the path is sheet1,What's wrong?
The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.
I have the following structure:OLD: frmMain (WinForm)uscStat (UserControl with Grid) In frmMain I'm able to make some settings and load the result of the settings via LinQ into the Grid of the uscStat.
