I am tired of googling about how to use user.config instead of app.config in a managed C++ application. All I found was about C# and I can't figurate out how to translate to C++ (Properties namespace does not exist)
Anybody can put me in the way to learn about that? I need to know how to create, read and write a user.config file.
Thank you
Follow this steps and it will work like desired:
1 - Add a reference to System.Configuration
2 - Add New Item > Visual C++ > Utility > Configuration file
3 - Open app.config and add your settings for example:
<configuration>
<appSettings>
<add key="greeting" value="Hallo world!" />
</appSettings>
</configuration>
4 - Copy the app.config to the output folder in the post build event: goto Project Properties > Configuration Properties > Build Events > Post-Build Events > Command Line and add this:
copy app.config "$(TargetPath).config"
5 - Read your settings:
String^ greeting = ConfigurationManager::AppSettings["greeting"];
Console::WriteLine(greeting);
Here's an AppConfigDemo project in C++/CLI.

We have a very strange problem with our VSTO Add-In.
In our Add-In there are label controls that read label text values from an app.config file and display text from the configuration file to the user:
<!-- app.config -->
<configuration>
<configSections>
...
</configSections>
<!-- start applicationSettings -->
<applicationSettings>
<OurVSTOAddIn.MySettings>
<setting name="ackMsg" serializeAs="String">
<value>Some text here that we want to display and change</value>
</setting>
...
<OurVSTOAddIn.MySettings>
</applicationSettings>
</configuration>
'vb.net code
objCheckDialog.lblAttachmentsMsg.Text = My.Settings("attachmentsAckMsg").ToString()
objCheckDialog.lblAttachmentsMsg.Visible = True
We recently updated the app.config file to replace English display information with Kanjii for our end-users in Japan.
When we rebuilt the MSI and installed on our test machine, the add-in isn't displaying Kanjii (although it display correctly in development).
Now we're wondering if the configuration file in the installation directory is being read at all or if the information is cached or the add-in is reading from another file somewhere.
What's even more strange is that we've changed other values in our app.config file that are being used in code logic, and these seem to load properly.
We're currently using Procmon in an effort to find out how the config file is loaded, however, while filtering on the following:
Process Name contains Outlook
Path Contains "OurOutlookPlugInName"
This produces over 400 results but we don't see any file handling for our config file unless I debug the code in Visual Studio.
On our installation machine, we also removed the configuration file from the installation directory thinking this might be a clue as to whether the Add-In is reading the configuration file from the installation directory, but it had no effect, and the Add-In loaded normally displaying English instead of Kanjii again.
All of the configuration settins are at the Application Level.
Is there a way for us to tell where our Add-In is loading our configuration file from?
Have we done something incorrect in our MSI build that would prevent the updated configuration file from loading?
UPDATE:
I opened the dll file in the C:\Program Files (x86)\OurVSTOAddIn installation directory using Telerik JustDecompile to see if the configuration settings were written somewhere in the dll and I can see that under OurVSTOAddIn->My Settings there are definitely DefaultSettingValues there, as shown below:
This would make sense since these are Application Scoped Settings and this would prevent a user from changing config settings.
But I'm thinking if we use Application Scoped variables, each time we'll need to rebuild the msi for release, which doesn't make sense to me since the reason we want to use configuration settings for the project is to not need to rebuild for configuration changes.
I can't get MS Build to output a transformed Web.Config file. I've setup the build project using NuGet package restore as described in the NuGet docs. Every part of the build works (package restore, CI, web deploy packages) except for the transform. I have tried the base setup and a custom project file as well as lot of other options and I haven't gotten anywhere.
I've done config transform setups before without issue. I have Slow Cheetah installed and can preview my current transform and see that it works. When I run the build locally via MSBuild.exe, the transform actually happens:
TransformWebConfigCore:
Transforming Source File: G:\MyProject\Web.config
Applying Transform File: G:\MyProject\Web.Debug.config
Output File: obj\Debug\TransformWebConfig\transformed\Web.config
Transformation succeeded
(If I look at the -v output I can see the individual transform run)
Then Web Deploy parameterizes my web.config:
Transformed Web.config using G:\MyProject\Web.Debug.config into obj\Debug\TransformWebConfig\transformed\Web.config.
PipelineTransformPhase:
Publish Pipeline Transform Phase
PreAutoParameterizationWebConfigConnectionStrings:
Creating directory "G:\MyProject\obj\Debug\CSAutoParameterize\transformed\Views\".
Copying obj\Debug\TransformWebConfig\transformed\Web.config to obj\Debug\CSAutoParameterize\original\Web.config.
AutoParameterizationWebConfigConnectionStringsCore:
Transforming Source File: G:\MyProject\Views\Web.config
Applying Transform File: <?xml version="1.0"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<connectionStrings>
<add
connectionString="{% token='$(ReplacableToken_#(parameter)_#(tokennumber))' xpathlocator='name' parameter='$(name)-Web.config Connection String' description='$(name) Connection String used in web.config by the application to access the database.' defaultValue='$(connectionString)' tags='SqlConnectionString' %}"
xdt:Transform="SetTokenizedAttributes(connectionString)" xdt:SupressWarnings="True" />
</connectionStrings>
</configuration>
No element in the source document matches '/configuration/connectionStrings'
Not executing SetTokenizedAttributes (transform line 6, 15)
Output File: obj\Debug\CSAutoParameterize\transformed\Views\Web.config
Transformation succeeded
PostAutoParameterizationWebConfigConnectionStrings:
Auto ConnectionString Transformed obj\Debug\TransformWebConfig\transformed\Web.config into obj\Debug\CSAutoParameterize\transformed\Web.config.
The parameterized file is then moved into the package and the transformed file is deleted.
Copying obj\Debug\CSAutoParameterize\transformed\Web.config to obj\Debug\Package\PackageTmp\Web.config.
Deleting file "obj\Debug\CSAutoParameterize\transformed\Web.config".
So I have a transformed web.config file that doesn't end up in my build output. Why does the transform happen but not get copied to the output directory or the web deploy package?
I had the same issue here. This is caused by the Web Deploy Pattern. It uses the "project name".SetParameters.xml in the Web_Package to replace values on Deploy.
Since you want to use SlowCheetah you need to circumvent this.
You can accomplish this by replacing the connectionstrings setting in your web.config by:
<connectionStrings configSource="connectionStrings.config">
</connectionStrings>
Of course you will need the connectionStrings.config file. You van create this manually and put in the originasl connectionStrings section.
The node should be the only node in the file.
Now you can add SlowCheetah Transform on your connectionStrings.config file.
I have written a NUnit tests for a .NET application. When I run the NUnit, it does not read the connection string values from the configuration file. I tried many solutions with out success, like
Adding <assembly name>.dll.config file in the path where NUnit loads the DLL file.
Adding the configuration settings in NUnit.exe.config/NUnit.gui.config
I wasn't able to read the configuration setting even when run in VSNunit. Is there a solution?
I've assumed
Assembly being tested: SomeNameSpace.MyClassLib
NUnit assembly with unit tests: SomeNameSpace.MyClassLib.Test
Try this:
Make sure that you have also copied your app.config to your NUnit Test DLL class library (i.e. project SomeNameSpace.MyClassLib.Test) as well.
Build your NUnit Project (e.g. to SomeNameSpace.MyClassLib/bin/debug) and make sure that following are in the bin\debug (or release) directory
the assembly to be tested,
the NUnit test DLL and
the configuration (SomeNameSpace.MyClassLib.Test.config)
any other assemblies needed by your DLL file being tested.
Edit your NUnit Project in the XML view of the NUnit GUI Project editor (menu Project → Edit, or just edit it in Notepad), and make sure that the test assembly (MyClassLib.Test.dll) and the configuration file names are relative to your appbase
For example,
<NUnitProject>
<Settings activeconfig="Debug" processModel="Default"
domainUsage="Default"
appbase="C:\Temp\MyProject\MyClassLib.Test" />
<Config name="Debug" binpathtype="Auto"
configfile="bin\Debug\MyClassLib.Test.dll.config">
<assembly path="bin\Debug\MyClassLib.Test.dll" />
</Config>
<Config name="Release" binpathtype="Auto" />
</NUnitProject>
Add an app.config file to the test project and add your configurations in there.
You then have to tell NUnit what configuration to use as by default it will not pick up the app.config file.
More information on how to set this up with screenshot.
I was stuck on a similar issue for a while. We also need to look at how you are loading the assemblies, based on that the naming of configuration file changes (unless you are using an explicit configuration file from settings). As mentioned here:
http://www.nunit.org/index.php?p=configFiles&r=2.2.10
If a single assembly is being loaded, then the configuration file is given the name of the assembly file with the config extension. For example, the configuration file used to run nunit.tests.dll must be named nunit.tests.dll.config and located in the same directory as the DLL file.
If an NUnit project is being loaded, the configuration file uses the name of the project file with the extension changed to configuration. For example, the project AllTests.nunit would require a configuration file named AllTests.config, located in the same directory as AllTests.nunit. The same rule is followed when loading Visual Studio projects or solutions.
In several projects’ App.config file, there is a line
<add key="url" value="http://www.example.com/"/>
Upon each build, I want to have a task to verify that the "url" key does not have the text "http://localhost". Is there a way to do this?
I'm assuming you have a team, and some of your team members inadvertently checkin those configs, changing that value to localhost.
If this is the case, why not have transform files for each environment, where your debug configuration can set the key to localhost, and your production/test/stage/qa/whatever configuration can set it to example.com or something else.
You might not have been aware that msbuild can transform your config files. Essentially you have your main config file, and then a config file containing just the things changed, for each environment. Upon doing a build, msbuild will modify the main one with whatever the changes are in the other "transform" files.
App.Config Transformation for projects which are not Web Projects in Visual Studio 2010?
Your transform file would look like:
<?xml version="1.0"?>
<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<appSettings>
<add key="url" value="http://www.example.com/" xdt:Locator="Match(key)" xdt:Transform="SetAttributes"/>
</appSettings>
</configuration>

They can easily be used on web.configs, as well as app.configs, with a little tweaking to your project file.
An alternative solution would be to integrate unit tests as part of your build, and have the test verify the key in your web.config.
Go to your builds:
Right click on your build and click on edit build definition:
Choose process:
Now we can set fail on build here:
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?
Dim SharedDrive As String = ConfigurationManager.AppSettings("scriptsfolder")
<configuration>
<appSettings>
<add key="scriptsfolder" value="C:\BadTempScripts"/>
</appSettings>
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".
A library runs in the context of an application, not by itself.
You need to put the configuration in the .config file of the application that will use the library.
So, if your library is lib.dll and the application is myApp.exe, you should use a .config file myApp.exe.config.
As an alternative for using a .config file, consider passing in the configuration as a dependency to your library types.
You have a specific bug in your code, in that you are trying to call a key Scripts where your configuration has a key scriptsfolder.
I had the same problem, and, as Oded tell us, a library run in the context of an application, however I was unable to solve the problem. In the end I used this code:
Dim config As Configuration = ConfigurationManager.OpenExeConfiguration(Application.ExecutablePath);
Dim k as KeyValueConfigurationElement = config.AppSettings.Settings
("SVCInstalled")
If k <> Nothing Then
If k.Value <> Nothing Then
' Process your data next
