    <p>The hack in the linked question works if it is used before the configuration system is used the first time. After that, it doesn't work any more.<br> The reason:<br> There exists a class <code>ClientConfigPaths</code> that caches the paths. So, even after changing the path with <code>SetData</code>, it is not re-read, because there already exist cached values. The solution is to remove these, too:</p> <pre><code>using System; using System.Configuration; using System.Linq; using System.Reflection; public abstract class AppConfig : IDisposable { public static AppConfig Change(string path) { return new ChangeAppConfig(path); } public abstract void Dispose(); private class ChangeAppConfig : AppConfig { private readonly string oldConfig = AppDomain.CurrentDomain.GetData("APP_CONFIG_FILE").ToString(); private bool disposedValue; public ChangeAppConfig(string path) { AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", path); ResetConfigMechanism(); } public override void Dispose() { if (!disposedValue) { AppDomain.CurrentDomain.SetData("APP_CONFIG_FILE", oldConfig); ResetConfigMechanism(); disposedValue = true; } GC.SuppressFinalize(this); } private static void ResetConfigMechanism() { typeof(ConfigurationManager) .GetField("s_initState", BindingFlags.NonPublic | BindingFlags.Static) .SetValue(null, 0); typeof(ConfigurationManager) .GetField("s_configSystem", BindingFlags.NonPublic | BindingFlags.Static) .SetValue(null, null); typeof(ConfigurationManager) .Assembly.GetTypes() .Where(x =&gt; x.FullName == "System.Configuration.ClientConfigPaths") .First() .GetField("s_current", BindingFlags.NonPublic | BindingFlags.Static) .SetValue(null, null); } } } </code></pre> <p>Usage is like this:</p> <pre><code>// the default app.config is used. using(AppConfig.Change(tempFileName)) { // the app.config in tempFileName is used } // the default app.config is used. </code></pre> <p>If you want to change the used app.config for the whole runtime of your application, simply put <code>AppConfig.Change(tempFileName)</code> without the using somewhere at the start of your application.</p>

    3. CO@Daniel That was awesome -- I worked it into an exentension method for ApplicationSettingsBase, so that I can call Settings.Default.RedirectAppConfig(path). I'd give you +2 if I could!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
