Issue in Batch execution at Server side

Question

Hi,

I have a requirement to execute a batch at server side. This batch creates some files in the server. When ever I am running the following code, I am not getting any output of created files and more over command window is not opened in server .

System.Diagnostics.Process myprocess = new System.Diagnostics.Process(); // Declare New Process

System.Diagnostics.ProcessStartInfo lObjProcInfo = new System.Diagnostics.ProcessStartInfo();

lObjProcInfo.UseShellExecute = false;

lObjProcInfo.RedirectStandardOutput = true;

lObjProcInfo.CreateNoWindow = true;

lObjProcInfo.RedirectStandardInput = true;

lObjProcInfo.WindowStyle = ProcessWindowStyle.Normal;

lObjProcInfo.CreateNoWindow = true;

lObjProcInfo.FileName = lStrBatchPath;

myprocess = System.Diagnostics.Process.Start(lObjProcInfo);

Please help out.

Thanks

Hi I tried to log output of the batch file run. noticed that after running batch file it directly eneterd into myprocess_Exited event with out any myprocess_OutputDataReceived or myprocess_ErrorDataReceived. It seems when running batch actually batch is not been executed...but batch is running on server properly on manual execution any help over here plzz.... revised code... System.Diagnostics. lObjProcInfo.UseShellExecute = lObjProcInfo.CreateNoWindow = lObjProcInfo.RedirectStandardOutput = lObjProcInfo.RedirectStandardInput = lObjProcInfo.RedirectStandardError = lObjProcInfo.WindowStyle = lObjProcInfo.FileName = lStrBatchPath; System.Diagnostics. ProcessStartInfo lObjProcInfo = new System.Diagnostics. ProcessStartInfo (); false ; true ; true ; true ; true ; ProcessWindowStyle .Normal; Process myprocess = new System.Diagnostics. Process (); // Declare New Process myprocess.EnableRaisingEvents = myprocess.OutputDataReceived += myprocess.ErrorDataReceived += myprocess.Exited += myprocess.StartInfo = lObjProcInfo; myprocess.Start(); myprocess.BeginOutputReadLine(); myprocess.BeginErrorReadLine(); myprocess.WaitForExit(); true ; new System.Diagnostics. DataReceivedEventHandler (myprocess_OutputDataReceived); new DataReceivedEventHandler (myprocess_ErrorDataReceived); new EventHandler (myprocess_Exited); -------------------------------------------- public { void myprocess_OutputDataReceived( object sender DataReceivedEventArgs e) try { } { } } { clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .INFORMATION e.Data); catch ( Exception ex) clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .ERROR ex.Message.ToString()); public void myprocess_Exited( object sender EventArgs e) try { } { } } { clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .INFORMATION Exited (Event) - Batch execution completed ); catch ( Exception ex) clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .ERROR ex.Message.ToString()); public void myprocess_ErrorDataReceived( object sender DataReceivedEventArgs e) try { } { } } clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .ERROR e.Data); catch ( Exception ex) clsAppLogger .mFnLogError( clsAppLogger . enumLoggerType .ERROR ex.Message.ToString());

Have you tested the program? You need to test it to ensure that the code will work. You also need to put in some diagnostic code that puts error information someplace so you can daignose the problem. For testing purposes take out (comment out) the lines (there are two of them) that set CreateNoWindow to true so you can see the window to determine if there is an error shown. Your code sets RedirectStandardOutput and RedirectStandardInput to true. Ensure that you have code to write the input and read the output.
