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 .

C#
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
Sreenath

It seems to be a permission issue. The default account under which ASP.NET application runs has very limited permissions due to security reasons and that account probably do not have permission to start a command prompt.

You will either have to assign required rights to that account or start the process using an account which has required permissions. Process.Start()[^] has an overload for that.

I would suggest Google for ASP.NET worker process permissions to know more about it.

Hope this helps!

Hi, I am running this application on IIS 5 and impersonated with Admin credentials.

Can you check the event log if there is anything relevant logged?

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

lObjProcInfo.UseShellExecute = false;
lObjProcInfo.CreateNoWindow = true;

lObjProcInfo.RedirectStandardOutput = true;
lObjProcInfo.RedirectStandardInput = true;
lObjProcInfo.RedirectStandardError = true;

lObjProcInfo.WindowStyle = ProcessWindowStyle.Normal;

lObjProcInfo.FileName = lStrBatchPath;

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

myprocess.EnableRaisingEvents = true;

myprocess.OutputDataReceived += new System.Diagnostics.DataReceivedEventHandler(myprocess_OutputDataReceived);
myprocess.ErrorDataReceived += new DataReceivedEventHandler(myprocess_ErrorDataReceived);
myprocess.Exited += new EventHandler(myprocess_Exited);

myprocess.StartInfo = lObjProcInfo;

myprocess.Start();

myprocess.BeginOutputReadLine();
myprocess.BeginErrorReadLine();

myprocess.WaitForExit();



C#
-------------------------------------

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());
            }

        }
