Hello all,
I was asked to make some changes in a code that was written and worked fine.
basically the code creates a script for each machine and a main script to run all the scripts on each machine using Psexec. The main script i need to run using Process.Start(<script name>) and have all the output and error messages written to a log
file, and i need to do this async (using backgroundworker) so the UI will not freeze.
for some reason when I run the main script from DOS everything is OK but when using C# code it doesn't work and doesn't give me any logs.
I should state that i'm running on clustered servers if it makes any difference. The code I use:
BackgroundWorker worker = new BackgroundWorker();
void RunProcessAsync()
{
ProcessStartInfo psi = new ProcessStartInfo(c_MainScriptName)
{
psi.RedirectStandardError = true,
psi.RedirectStandardInput = true,
psi.RedirectStandardOutput = true,
psi.UseShellExecute = false,
psi.CreateNoWindow = true
};
Process p = Process.Start(psi);
if (p != null)
{
p.OutputDataReceived += new DataReceivedEventHandler(p_OutputDataReceived);
p.ErrorDataReceived += new DataReceivedEventHandler(p_ErrorDataReceived);
p.BeginErrorReadLine();
p.BeginOutputReadLine();
worker.RunWorkerCompleted += ProcessedFinished;
worker.DoWork += WaitForProcess;
}
}
void ProcessedFinished(object sender, RunWorkerCompletedEventArgs e)
{
Process p = e.Result;
p.CancelErrorRead();
p.CancelOutputRead();
worker.RunWorkerCompleted -= ProcessedFinished;
worker.DoWork -= WaitForProcess;
}
void WaitForProcess(object sender, DoWorkEventArgs e)
{
Process p = e.Argument;
p.WaitForExit();
e.Result = p;
}
(sorry it's so long)
As i said the script (that has in it a call to psexec) fails using these code but works using DOS, also it doesn't write all the log files but only a bit, usually states exit code 1.
anyone has any idea what to do so this will work?
thanks
