Load App.Config At Runtime?
Jan 17, 2012
I am creating a test project using IBM's Rational Functional Tester(RFT) tool(we are using the VB version of it and it only supports till .net 3.5).In this project I am making all database queries using the entity framework.The problem is entity framework retrieves "Metadata", "Connection String" etc from the App.Config file,and RFT won't let me add a App.Config to the project(I guess it is designed that way -- I googled adding an App.Config file to an rft project and came up with nothing), and the Entity Framework requires you to have the app.config file at the entry point.I was building the string to pass to entity framework in code, but my boss really does not like that. So looking at my options I think any of the below 2 solutions should suffice
Is their any way to load an App.Config during run-time. Is their any way to add an App.Config to an RFT project(should really be my first question).

I need to allow my end users to update configuration settings, such as the location of a data file. I am storing this in app.config - which is referenced as .exe.config in a deployed situation. The problem is in Windows 7 the user doesnt' have write access to that file. How do i allow the users to write to this file, or optionally prompt for administrator access only when writing to that file? Also open to moving the configuration to another location.

How do we overwrite config file at runtime. I have four config files for DEV, TEST, UAT, PROD. Based on user selection I need to overwrite the default config file completely with one of the selection specific config files. These config files not only have appsettings section, but also has complex cutom sections and subelements with lot of attributes. I need to overwrite and refreshsections dynamically at runtime. I know there are so many articles on editing appsettings sections. But I want to completely overwrite the entire file.

I want to load a dictionary at startup in my console app from my app.config. I know that I could use an xml library or linq to XML to load it to parse and traverse it. My question is there a BUILT IN way of doing it. Isn't there some way to add an application configuration section into the app.config and then have it loaded automagically using ConfigurationManager class in the System.Configuration namespace?

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 have some custom user controls (asp.net) that is loaded via a configuration file this works great..
Problem - Some of these user controls I made you set some parameters.
Example - oUCtrl = page.LoadControl("UserControls/" & oCtrlNode.Attributes("name").Value & ".ascx")
This loads the control.. now that node has more attributes.. example url="www.google.com" in the config file
<control name="RSSFeed" url="www.google.com"> To set the url on the control it would be oUCtrl.url = "www.google.com"
is there a way to enumerate the properties of a user control or a way to use something to eval a string like eval("oUctrl." & currentAttributeName & "=" currentAttributeValue)
Not sure the best way.. i would assume the best way would enumerate the public properties of the user control and compare against it.

I am working on an application which will be used to read/write/provide custom functionality using an mdb file. I have been able to create the program, and access my test mdb file just fine using the normal ado connection protocols. The final product will be used in an application/file format where each user will have thier own mdb file, and multiple users will be using the same application on the same computer to access their files. I need to figure out how to load the mdb file at runtime using both an open file dialog, and to be able to double-click the file in windows and have the applicaiton open and load the db that way (I know how to create file associaitons, it is just the databinding that I am having issues with- and the mdb file uses it's own filetype, so I won't step on the toes of MSACCESS).

I'm working with a 3rd party assembly to implement something in our in-house software. I can make the refence and work with the library without a problem, but when I run the program to test it i'm getting this error "Can't load file or assembly "assembly file" nor either of its dependencies. The system couldn't find the specified file" (i'm from Mexico, exception is in Spanish so i had to tanslate it, sorry for the poor translation) I have given read and write permission to the file, the folder, and for all users and still wont load it. I saw that the assembly has the PublicKeyToken=null, does that have any to do with that i cant load the assembly?

I am working on a project where I have to load assemblies (lets call them tasks) at runtime, run the task and then be able to kill off the whole assembly so that the dll can be replaced without interrupting the main application.There are many of these tasks running within the main application,some run sequentially and some run in parallel.Occasionally one or to of these tasks need to be updated and then re-added to the queue. Currently we are stopping the entire application and interrupting the other tasks at whatever stage they are at, which is not ideal.I have figured out that I will have to load each assembly into a separate AppDomain, but loading the assemblies in those domains is proving difficult, especially when I need to actually run the tasks and receive events from them.I have been looking into this problem for a couple of days and have still not managed to get a working proof-of-concept.
I have an Interface for the tasks which includes a 'run' and 'kill' method (subs) and a 'taskstep','complete' and 'killed' event.'taskstep' returns an object to be cached later, 'complete' fires when the whole task is done and 'killed' fires when it is ready to be unloaded.There should also be a timeout on the whole process of two hours and a timeout of 2 minutes on the killed event in case it gets stuck, at which point I would like to be able to unload it, forcing any threads to terminate (which is what 'kill' should do anyway).Each assembly may contain several tasks, all of which should loadable be unloadable.I have no problems loading these tasks as 'plugins' but am lost when trying to both use them and unload them. If I have to create some elaborate wrapper then so be it but is what I need even possible? I have tried inheriting from MarshalByRefObject but I do not even know the assembly fullname unless I load it first, which then locks the file. I have tried loading from a byte array of the assembly. This means that the file is not locked but a copy of it remains in the current appdomain. This will become problematic over the following months / years![code]

I apologize if this is a rudimentry question, but I have an application that makes several calls to several .dll's. I notice that the first time the function is called, it seems to take a very long time (about 10 seconds) for the functions to complete.

I have VC++ windows service running on a windows 2008 server which invokes a VB.NET exe with certain comandline parameters using CreateProcess(). VB.NET application has a form wich uses WithEvents to handle certain event. These event handlers are set in the Forms Load event. Problem here is when i debug the VB.NET application individually the application works fine, Forms Load event is getting fired. But when the exe is invoked via the windows service the form Load event does not get fired. Note the Forms Show function called and not showdialogue.
Why this was done i am not sure it was a VB 6.0 code which i have converted to VB.NET. But everything works fine when i debug the application individually on windows 2008 64 bit.

Not sure if this is the correct place for this postWhat I am trying to do is update dll's in my application.Using VB with dotnet 2 (Visual Studio 2010)The Project has a number of Dll's one of each department i.e. Sales is sales.dll... Development is development.dll etc....Each dll has classes/User controls which is used and dispose depending on the section within the application.Once work has been completed with a dll, it put in the deployment area, currently another is program launching checks the file verison and updates as required, before the main application lauches, this works. The exe hasn't needed updated for a long time as all the changes are in the dlls.
What i have been looking at is update method for the dll's dymanically, when not in use, when the dll called into use or disposed of.I have looking at LoadLibrary/FreeLibrary and application.domain. I have been reading loads and tried out some of the examples, with a modified to suit. I am just not getting it.

I am having another issue with WMP in VB.NET 2010.I wrote an app using WMP in VB.NET 2010, using .NET Framework 4.0 of course, but had to change the framework target to 3.5. After doing this, the WMP component does not work. How, if I even can, fix this problem so that the program will run on .NET Framework 3.5? The error says that it could not load AxInterop.WMPLib.dll because it was built in a runtime newer than the currently loaded one.

I'm creating an app to manage the movies I've watched and get some info about these movies and then display these info in labels.At moment I'm trying to load the "runtime" and "genre" into label3 (runtime) and label5 (genre). Once the movie name is clicked in the listbox control, these info are loaded from a website (webbrowser control) and then displayed in the labels. My question is: Is there any way to make the My.Settings save these info for EACH movie? Something like this:
Saving the info:
vb
If ListBox1.SelectedItem.ToString > 0 Then 'LOADING THE INFO CODE... 'SAVING... 'create: My.Settings.(ListBox1.SelectedItem.ToString & "1") = Label3.text 'create: My.Settings.(ListBox1.SelectedItem.ToString & "2") = Label5.textEnd If

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?
