    <p>You would need something server side that the application can use to find out what the most recent version is. Personally, I would go with a web service that returns the most recent version number and a url where it can be downloaded, but this could also be done with a static page that gets parsed for this information. The application starts up, checks it's version number to the one returned from the service. If the service reports a newer version use HttpWebRequest (or other method) to download the new version. If the new version is packaged as an installer you could then execute the installer and exit the currently running instance. If you want something more silent than an installer you will need a way of updating your exe in place. This is usually done by a 2nd application (the updater) that waits for the main application to exit and moves the new version of the exe in to place, then restarts the application. One thing to keep in mind is that for this to work the user that the application is running as will need to have permission to write to the program directory.</p> <p>If this is more of a corporate environment where you want to use fileshares you could do it differently. Have the program check a well known shared directory for a text file with the most recent version and the path to the update. Parse the text file for the information the same as above, and grab the new version from the specified path using the <code>system.io</code> namespace classes. It's basically the same operation, but using file paths instead of web requests.</p>

    1. COThis is definitely a corp. environment. In VS2010 if you open the solution properties and go to Publish you can click Updates... and use that to specify where the program should check for updates. The trouble is that this method doesn't allow users to defer updates and it requires the user to open the app twice before the update is installed. In a Windows app you can use `System.Deployment.Application.ApplicationDeployment.CurrentDeployment.UpdateAsync()` to force an update and then close the app once it's done. I find it hard to believe that console apps don't have something similar.

    2. COMy understanding is that all of that relies on the ClickOnce framework which you said you wanted to avoid.

    3. COWell then clearly I have been misinformed about ClickOnce. If I am currently using it in my Windows apps then I never realized it. lol

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.
