    <p>I recently build a tiny app where I was interacting with batch files. I found this snippit of code that allowed me to do this:</p> <pre><code>Process proc = new Process { StartInfo = { RedirectStandardError = true, RedirectStandardOutput = true, UseShellExecute = false, } }; proc.Start(); string errorMessage = proc.StandardError.ReadToEnd(); proc.WaitForExit(); string outputMessage = proc.StandardOutput.ReadToEnd(); proc.WaitForExit(); </code></pre> <p>From here, just direct those strings into a usercontrol of your choice.</p> <hr> <p>EDITS </p> <blockquote> <p><strong>Note</strong>: This is not a general solution. It can lead to deadlocks. From the doc for <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.processstartinfo.redirectstandarderror.aspx" rel="nofollow noreferrer">RedirectStandardError</a>:<br> Synchronous read operations introduce a dependency between the caller reading from the StandardError stream and the child process writing to that stream. These dependencies can cause deadlock conditions. When the caller reads from the redirected stream of a child process, it is dependent on the child. The caller waits for the read operation until the child writes to the stream or closes the stream. When the child process writes enough data to fill its redirected stream, it is dependent on the parent. The child process waits for the next write operation until the parent reads from the full stream or closes the stream. The deadlock condition results when the caller and child process wait for each other to complete an operation, and neither can continue. You can avoid deadlocks by evaluating dependencies between the caller and child process. </p> </blockquote>

    1. COIn fact this will not work, because there is a race condition between stderr and stdout. Suppose the process you run writes first to stdout, then to stderr. By calling ReadToEnd() on stderr, you will wait forever. On the other hand if the process writes in the opposite order, then reading from stderr is ok. But there is no guarantee. Hence a race condition. You need to use async reads to avoid this race. See the doc on Process.Start() for more info.

    2. COI guess that's why this code led to my batch window freezing up at times. I had I feeling that something might have been out of whack. I am going to leave my answer incorrect for educational purposes.

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.
