POCalling executable using Process crashes intermittently
text
Body
copied!<p>I am calling an executable in C#. When the executable runs, it writes out to the console so the C# code is getting the console output and writing it to a text file. When the crash happens a couple of things occur.</p> <p>1) The output of the text file is not completely written out. 2) The executable process seems to run completely through because it generates a report just like a successful run.</p> <p>I suspect that the reason for this crash is because of how I'm writing the file out.</p> <p>Update: - As far as the crash, a dialog comes up saying that the "Manager has encountered a problem and needs to close. We are sorry for the inconvenience." Then it has an OK button. When you click OK, there is a dialog that I have setup that asks if I want to start the manager again.</p> <ul> <li>The manager application that is calling the executable is single threaded. The executable may run multi-threaded.</li> </ul> <p>Here is a small snippet of the call:</p> <pre><code> // Set up process to redirect standard output and standard error to // a file. process.StartInfo.UseShellExecute = false; process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; FileInfo ofi = new FileInfo(outputPath); FileStream ofs = ofi.OpenWrite(); StreamWriter sw = new StreamWriter(ofs); WriteToTextWriterEventHandler wtsweh = new WriteToTextWriterEventHandler(sw); DataReceivedEventHandler handler = wtsweh.HandleDataReceived; process.OutputDataReceived += handler; process.ErrorDataReceived += handler; // statusAcceptor.ReportStatus("Running process."); process.Start(); process.BeginOutputReadLine(); process.BeginErrorReadLine(); statusAcceptor.ReportStatus("Waiting for process to complete."); process.WaitForExit(); int processExitCode = process.ExitCode; process.Close(); sw.Close(); // private class WriteToTextWriterEventHandler { private TextWriter tw; public WriteToTextWriterEventHandler(TextWriter tw) { this.tw = tw; } public void HandleDataReceived(object sendingProcess, DataReceivedEventArgs outLine) { // Collect the sort command output. if (!String.IsNullOrEmpty(outLine.Data)) { tw.Write(Environment.NewLine + outLine.Data); } } } </code></pre>
