Access An Appsettings Key Value In .net 2.0 Web Application?
Jun 17, 2011
I've trying to access an appsettings key value in my vb.net 2.0 web application.I've put the key in the app.config file:
<appSettings>
<add key="DownloadURL" value="http://<myURL>/" />
</appSettings>
I've followed the instructions here, and it says that I need to access this key like so:
URL = System.Configuration.ConfigurationSettings.AppSettings("DownloadURL")
But I get the following message:
Public Shared Readonly property
AppSettings() As
'System.Collections.Specialized.NameValueCollection'
[code]....
I tried to replace the old method with the new one, but it does not exist.Strange, since I've done a similar thing with a web app and it did exist there.

I am trying to access appSettings using the following syntax and I have used it before in my many website projects but not in a class library project. In this class library project I cannot even access the AppSettings Keys. Is there any way I could access the AppSettings Key from my class? Is the class library project's app.config or project structure behave in a different way?
[Code]...
I have already added Project Reference to System.Configuration and imported in my class. When I run my code it says, "Object not set to an instance of any object".

There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

What is the purpose of the <Clear > XML element within the <AppSettings> tag in an application's config file?I see it removes previously added settings (see code below), but why would you want to do that? [code]I also understand that when manipulating app settings in code you could clear existing keys, but why have the <clear> XML element?Also, out of habit really, i've been putting the <clear> element before any <add> elements. Do i need to do this, should i not be doing this?

I've been linking to an external config file using <appSettings file="blah"> since VS 2003. I just created my first 2010 project, and I get no data from my file, nor any error. [edit]This functionality works as expected when I point to 3.5 framework.Another note, if I copy the other config to the debug directory and reference it by file name it works. When I use the UNC path it doesn't. The UNC path has worked for many of my past projects. Maybe it's a 4.0 security setting somewhere?

I have built a functionality where I want to back up the database - [Access]. Currently, its working but the user has to specify the file. I used a FileOpenDialog Box to get the file, saved it in a textbox and copied it to another directory. That works good. What I want now is the user doesnt have to know the lcoation of the Database. So, I just want to copy the Database File using the Configuration.Appsettings. He can specify the directory the file needs to be copied to. The Access DB is referenced as follows:
<connectionStrings>
<add name="TestCMS.My.MySettings.CMSConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|CMS.mdb"
providerName="System.Data.OleDb" />
</connectionStrings>

I'm using VS 2010, and I did a project using VB and a database in Access. The problem is that when I try to put that "application" on other computers, sometimes, is not working. I thought it can be because on these computers they don't have access, but on one computer, is running another app which is using Access and there is no Access installed. How can I check if my application requires Access to be installed or not?
Here is a example of how I did the connection:
Public AccessOLEDBConnString= "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & myfullpath & ";Jet OLEDB:Database Password=password"
Function getConnection() As OleDb.OleDbConnection
[CODE]...
And when I want to have access at the data I'm doing like this:
dim conn as Oledb.OledbConnection
dim sql as string
dim ds as Dataset
[CODE]...

My boss gave me an MS Access application that was developed by our former colleague. He wants me to convert that application to VB.Net Windows form application. I went through the MS Access Application. It contains tables, queries, forms, reports and macros. I could not find the programming (Where is the code written in MS Access?). My boss wants the windows application to be same as the MS Access Application (both in design and logic). I don't how will i develop the windows form. How can I achieve this?

I need to be able to interact with an application's GUI within another application. Basically, I would like to run an application and have it's GUI appear in a MDI-style Form in my application. Is such a thing possible? The reason I need to do this is because I need to access an application remotely without having to use Remote Desktop or similar tool. Any questions on this, feel free to post.

I'm currently trying to convince management of the need to port one of our applications to .NET. The application has grown to be a bit of a monster in Access (backend in SQL), with 700 linked tables, 650 forms/subforms, 130 modules and 850 queries.
I pretty much know all the major benefits of doing this, but now need to look at how this can be achieved technically, so I can put a project plan together.So, my plan was to convert the queries into stored procedures and/or views on the backend and re-write the forms in WPF or WinForms.
Now, the code is where I come unstuck. Is it possible to packaged up the code behind and modules into dlls and consume them whilst it is slowly ported to VB/C#?
What we can't be left with is half an application in VB/C# and half in Access, it must 'appear' to all be one application, even half way through the migration.EDIT: Just some more info about what we do and why we're looking at moving away from Access.We are essentially an ISV and the Access application is our main product. This application has been developed over a period of 15 years, by many, many developers on an ad hoc basis. There is no documentation for this application.
We also have problems with getting branching in SCC to work properly, so we've currently got 4 or 5 code bases for the half a dozen clients we have. On top of that, all the testing we do is completely manual, which you can imagine is very labour intensive, and only scratches the surface of what really needs to be tested.We're currently looking to expand, and have a number of sales leads that are in the final stages. I'm worried that with these new sales, we're going to be swamped with support and testing, and that this application is going to become even more entangled an buggy.
I'll also add to this the fact that we're just about to enter the spec phase of a brand new product, which is almost certainly going to be built in .NET. If we were to rewrite the Access application in .NET, then the people we use for that can go straight on to this new development. If we were to stay in Access, then we'd have to get some new Access people in, whom would have to be retrained once we start the new development.
So essentially it has come down to two choices, major refactoring work in Access to try and 'organise' the code a bit better, and those of you who have suggested culling parts are most probably right; I'm sure there are parts that are no longer used. However, I fear that if we stay in Access we still won't be able to build in effective testing and we still won't have proper SCC branching, which will lead to support continuing to be a nightmare, and any future developments on this product makings things worse. Either way there is a lot of work that we're about to embark on, which is either going to be done in Acces, or .NET.

I have a web service that I will need to add as a web service reference in my vb.net application which is a plug-in to Outlook. I initially tried adding the reference by right clicking on the Project and selecting "Add Service Reference". In the box that pops up, I type the web service url in the address field and the namespace name and click ok.

I have an application which is grouped in a MainApplication and serveral Modules (DLL's) The Main Application is basicly a Form with a NavigationBar on the Left Side (like in Outlook 2003) and an MDI-Parent. There is also a Simple Login Routine on this Form. I store the UserName after Loggingn to a Property. The DLL's holds functionallity and Forms for various Sections for example there is a Employee.dll which holds functions and a form to show all Employees.
On Loading of the Main Application I loop trough all dll's in a "Module"-Folder and extract NavigationItems from them which I add to the MainForms NavigationPanel. I don't have a reference to the Modules because I want to make it as flexible as possible so that it is possible to delete a Dll form the Module directory in order to remove the functionality from the MainApplication. The Modules could work also without the MainApplication if they are Complied as an exe insted of DLL of course. This works fine so far.
