    <p>I'm trying to run a local process using C# to call Powerpoint and convert a .pdf to a .ppt.</p> <p>I made a standalone console app, in hopes of reproducing and isolating the problem. Unfortunately, it works for the standalone version, but not with the integrated version.</p> <p>When it doesn't work, it throws no exceptions. It just silently fails to create the .pdf file.</p> <h2>NEW:</h2> <p>I'm getting an error on the event log:</p> <pre><code>Microsoft PowerPoint PowerPoint can't do this because a dialog box is open. Please close the dialog box to continue. P1: 400205 P2: 15.0.4420.1017 </code></pre> <p>I don't see any sort of dialog box when running the console commands, the standalone console application, or running the integrated web project on my local machine.</p> <p>The /pt command is supposed to be silent, as per <a href="http://office.microsoft.com/en-us/powerpoint-help/command-line-switches-for-powerpoint-2007-and-the-powerpoint-viewer-2007-HA010153889.aspx" rel="nofollow">the official documentation</a>.</p> <p>I can set the <code>Identity</code> of the <code>ApplicationPool</code> the project is running under to the user that I log in as, and I no longer get the above error in the event log. However, I get no other errors (that I can tell are related) from the event log.</p> <p>It still doesn't work, however. Powerpoint or PDFCreator still crashes, and doesn't create the .pdf.</p> <p>I also tried to run my working console app by calling it as a <code>Process</code> from my integrated issue, and that didn't work either.</p> <h2>The working console application:</h2> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System; using System.Diagnostics; using System.Text; namespace ConsoleApplication3 { class Program { static void Main(string[] args) { var psi = new ProcessStartInfo(); psi.FileName = "\"C:\\Program Files\\Microsoft Office\\Office15\\POWERPNT.exe\""; psi.Arguments = "/pt \"PDFCreator\" \"\" \"\" dd0e03ff-f386-4e65-b89d-72c7f1ee502d.pptx"; psi.WorkingDirectory = "C:\\Temp"; psi.CreateNoWindow = true; psi.ErrorDialog = true; psi.UseShellExecute = false; psi.WindowStyle = ProcessWindowStyle.Hidden; psi.RedirectStandardOutput = true; psi.RedirectStandardInput = false; psi.RedirectStandardError = true; try { using (Process exeProcess = Process.Start(psi)) { exeProcess.PriorityClass = ProcessPriorityClass.High; var outString = new StringBuilder(100); exeProcess.OutputDataReceived += (s, e) =&gt; outString.AppendLine(e.Data); exeProcess.BeginOutputReadLine(); var errString = exeProcess.StandardError.ReadToEnd(); if (!string.IsNullOrEmpty(errString)) { Console.WriteLine("errors reported 1"); } } } catch (Exception ex) { ex.ToString(); Console.WriteLine("Errors reported 2 "); Console.WriteLine(ex.ToString()); } Console.WriteLine(psi.FileName); Console.WriteLine(psi.Arguments); Console.WriteLine(psi.WorkingDirectory); } } } </code></pre> <p>It prints</p> <pre><code>"C:\Program Files\Microsoft Office\Office15\POWERPNT.exe" /pt "PDFCreator" "" "" dd0e03ff-f386-4e65-b89d-72c7f1ee502d.pptx C:\Temp </code></pre> <h2>The not working integrated application:</h2> <pre><code>using System; using System.Diagnostics; using System.Text; namespace CT.Services.Helper { public static class ExecutableRunner { public static ExecutableResult RunExeNamed(string exeFilename, string commandLineArgs) { return RunExeNamed(exeFilename, commandLineArgs, null); } public static ExecutableResult RunExeNamed(string exeFilename, string commandLineArgs, string workingDirectory) { var result = new ExecutableResult { WasSuccessful = true }; var psi = new ProcessStartInfo(); psi.FileName = "\""+exeFilename+"\""; psi.Arguments = commandLineArgs; if(!string.IsNullOrEmpty(workingDirectory)) { psi.WorkingDirectory = workingDirectory; } psi.CreateNoWindow = false; psi.ErrorDialog = true; psi.UseShellExecute = false; psi.WindowStyle = ProcessWindowStyle.Hidden; psi.RedirectStandardOutput = true; psi.RedirectStandardInput = false; psi.RedirectStandardError = true; try { // Start the process with the info we specified. // Call WaitForExit and then the using statement will close. using (Process exeProcess = Process.Start(psi)) { exeProcess.PriorityClass = ProcessPriorityClass.High; var outString = new StringBuilder(100); // use ansynchronous reading for at least one of the streams // to avoid deadlock exeProcess.OutputDataReceived += (s, e) =&gt; outString.AppendLine(e.Data); exeProcess.BeginOutputReadLine(); // now read the StandardError stream to the end // this will cause our main thread to wait for the // stream to close (which is when ffmpeg quits) var errString = exeProcess.StandardError.ReadToEnd(); if (!string.IsNullOrEmpty(errString)) { result.WasSuccessful = false; result.ErrorMessage = errString; } } } catch (Exception ex) { result.WasSuccessful = false; result.ErrorMessage = ex.ToString(); } Debug.WriteLine(psi.FileName); Debug.WriteLine(psi.Arguments); Debug.WriteLine(psi.WorkingDirectory); return result; } } public class ExecutableResult { public bool WasSuccessful { get; set; } public string ErrorMessage { get; set; } } </code></pre> <p>}</p> <p>it prints</p> <pre><code>"C:\Program Files\Microsoft Office\Office15\POWERPNT.exe" /pt "PDFCreator" "" "" dd0e03ff-f386-4e65-b89d-72c7f1ee502d.pptx C:\Temp </code></pre> <p>I would think that one of the strings I'm using as the file path or console command would be wrong, so I had them printed to the console, but you can see that those aren't the issue.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
