Some times this process exits because of exception. p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardError = true; p.StartInfo.FileName = "Write500Lines.exe"; p.Start(); // Do not wait for the child process to exit before // reading to the end of its redirected error stream. Here is some code you could use: ProcessStartInfo startInfo = new ProcessStartInfo(cmd, args); startInfo.UseShellExecute = false; startInfo.RedirectStandardError = true; Process someProcess = Process.Start(startInfo); string errors = someProcess.StandardError.ReadToEnd(); Note that if the For details about security demands, see Link Demands.ExamplesThe following code example demonstrates how to use the ProcessStartInfo class to start Internet Explorer, providing the destination URLs as ProcessStartInfo arguments. http://stackoverflow.com/questions/5005874/how-to-get-the-error-message-with-c-sharp

Standard Error Has Not Been Redirected

in that case your only option is to check for any error event the application might leave (could be a log file, Windows Event Log, message on stdout or stderr, etc.) When the caller reads from the redirected stream of a child process, it is dependent on the child. Otherwise, reading from the StandardError stream throws an exception.The redirected StandardError stream can be read synchronously or asynchronously.

  2. The caller waits for the read operation until the child writes to the stream or closes the stream.
  3. So after waiting for 5 seconds we check to see if the process is still running, if so we just go and kill it. # Start the process $process.Start() | Out-Null

To use this overload of Process.Start() (which is the only non static overload of the method) you need to create an instance of the Process class using a ProcessStartInfo object.

An example of this is below: ProcessStartInfo processStartInfo = new ProcessStartInfo("EXCEL.EXE"); Process process = new Process(); process.StartInfo = processStartInfo; if (!process.Start()) { // That didn't work } Though, given that this ProcessStartInfo myProcessStartInfo = new ProcessStartInfo(); try { myProcessStartInfo.UseShellExecute = false; myProcessStartInfo.RedirectStandardError = true; TestProcess.StartInfo = myProcessStartInfo; TestProcess = Process.Start( MyProcess , " -file "+ cfrmTRSobj.GetTRSFullFileName() ); SetProcID( TestProcess ); TestProcess.WaitForExit(); StreamReader How much interest did Sauron have in Erebor?
