C# process and net view

[Morpheus]

I would like to use the net send and net view MS-DOS commands for a project

For the net send, i'm using :

ProcessStartInfo myProcess_startinfo = new System.Diagnostics.ProcessStartInfo("C:\\WINDOWS\\system32\\net.exe","send x.x.x.x Hello World");


This one works fine but the net view command doesn't works and i don't know why :

ProcessStartInfo myProcess_startinfo = new System.Diagnostics.ProcessStartInfo("C:\\WINDOWS\\system32\\net.exe","view >> view.txt");



Any ideas ?



Thanks.

You seem to be right; I found your example didn't work (just as you said). This might be slight overkill, but I've found this to work.

I know this doesn't exactly address why your technique doesn't work, but I hope it solves your problem.

ExecuteAndWait( "net.exe", "view >> view.txt" );


private string ExecuteAndWait( string sFullApplicationPath, string arguments )
{
const int ERROR_FILE_NOT_FOUND =2;
const int ERROR_ACCESS_DENIED = 5;
string stdout = null;

Process myProcess = new Process();

try
{
myProcess.StartInfo.FileName = sFullApplicationPath;
myProcess.StartInfo.Verb = "Open";
myProcess.StartInfo.Arguments = arguments;
myProcess.StartInfo.CreateNoWindow = true;
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.RedirectStandardOutput = true;
myProcess.Start();
stdout = myProcess.StandardOutput.ReadToEnd();
myProcess.WaitForExit();
}
catch (Win32Exception e)
{
if(e.NativeErrorCode == ERROR_FILE_NOT_FOUND)
{
throw new Exception( e.Message + ". Check the path: " + myProcess.StartInfo.FileName );
}
else if (e.NativeErrorCode == ERROR_ACCESS_DENIED)
{
throw new Exception( e.Message + ". Access Denied. File " + myProcess.StartInfo.FileName + " could be in use." );
}
}

return stdout;
}

Note: you *could* use the returned string instead of view.txt, if you liked.
