    <p>I've tried two different methods for starting a process.</p> <p><strong>The first</strong></p> <p>The definition is defined as parameters to the Start method:</p> <p><code>System.Diagnostics.Process.Start("excel", string.Format("\"{0}\"", ExcelFileBox.Text.ToString()));</code></p> <p>My thoughts:</p> <p>This one starts just fine, but I don't know how to get feedback from it. </p> <p><strong>The second</strong> </p> <p>I started looking into <code>ProcessStartInfo</code> because I want to know if Excel started successfully or not--for instance, while it's very likely it exists on the user's machine, there's no guarantee and it would be silly for me to indicate to the user that it's started successfully when it hasn't.</p> <pre><code>System.Diagnostics.ProcessStartInfo startinfo = new System.Diagnostics.ProcessStartInfo { FileName = "excel", Arguments = string.Format("\"{0}\"", ExcelFileBox.Text.ToString()), ErrorDialog = true, UseShellExecute = false, WorkingDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) }; try { System.Diagnostics.Process.Start(startinfo); } catch (Exception err) { Console.WriteLine(err.Message); } </code></pre> <p>My thoughts:</p> <p>This gives the error: "The system cannot find the file specified", but it's unclear whether it means the Excel application or my file. In any case, while I appreciate the error message ability, I shouldn't be receiving out at the moment.</p> <p>Thought, suggestions, ideas on how to know if this happened successfully?</p> <p><strong>Solved</strong></p> <p>I put the first way of starting a process into a try-catch and it works beautifully.</p>

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.
