Re: Running PSexec within C# - C# Discussion Boards

26-Nov-10 3:15

Hi C# Guru's,

i have recently written a command line C# app that uses psexec to run Netstat on remote machines and sends the results to a text file, it works ok...ish.

firstly, even though i have set the process to psi.UseShellExecute = false and psi.CreateNoWindow = true it still pops up a command window - any idea how i stop this?

secondly, even though it sends most of the output to the text file it cuts it off short, i have used the below code TNA.
while(p.StandardOutput.EndOfStream == false)
{
sw.Write(p.StandardOutput.ReadToEnd());
p.WaitForExit();
sw.Flush();
}

the bottom part of the output file looks like:
TCP 172.17.134.138:80 172.17.134.133:51076 TIME_WAIT 0
TCP 172.17.134.138:80 172.17.134.133:52450 TIME_WAIT 0
TCP 172.17.134.138:80 1

any ideas on how to get the full output?

Many Thanks,

Phil

Hi,

your code looks only so so, with a loop, several ReadToEnd and a flush.

assuming you save all incoming text to a file, there is no need to catch it while the netstat app is still running, so simplify your code to first wait for netstat to exit, then wait 500 msec to make sure everything has settled, then just once read all its output; assuming you close the output stream (or use a using statement) there is no need to flush either.

p.WaitForExit();
Thread.Sleep(500);
string s=p.StandardOutput.ReadToEnd();
File.WriteAllText(filepath, s);

Hi Luc,

thanks for your speedy reply.... it still doesn't work! Frown | :(

i still get the same result, it cuts of some of the output.

when i run psexec manually it does give some output and then pauses for the server to reply with more data. i think this is the point where it cuts out.

i'm open for any more suggestions! Smile | :)

many thanks,

Phil

Luc Pattyn30-Nov-10 3:34

is it repeatable, i.e. does it always produce the exact same output?
if so, can you show the output?
could it be that the target app launches yet another app, whose output is exactly what gets lost?

Hi All,

Is there any way to know what is my public IP??
example say my public IP is 202.214.215.12

How would I know my IP??

Please dont say ipconfig.

Thanks,
Sunil G.

Yes, there is a way, you could ask your NAT device what its (and therefore also your) public IP address is.

Hi,

you could use UPnP of your router Wink | ;-)

MonoTorrent can do it (UPnP and NAT-PMP), Windows has stuff for this build-in as well but it's not very reliable (IIRC it depends on a service which can be disabled), and you could read my article (it's a little old though)

Try a Google search, there are quite a few sites that can find this information for you. I think one of them may even be called "whatsmyip.com".

Just say 'NO' to evaluated arguments for diadic functions! Ash

IMO the only reliable way is by asking the external world. Here[^] is one of many sites that may help.

I wrote a command line tool in C# (code included) that will use a service on my server to pull external IP.

My router registers at dyndns.org, so I can query the IP address for my dyndns name.

Hi , have a good day ,

I have an Indicator Weight connect to COM port on My Pc ,

When I press the "Print Button" on the Indicator it sent weight to the Com Port ,

And I receive the data by this events :

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
     TxtOutPut.Text = serialPort1.ReadExisting();
}

So far so good ,

The Only problem I had is that When I press The "Print Button" on the indicator "
The DataReceived Firing 5 times , Before all the data sent , For Example :
The indicator Show The Weight on it's screen Like "US,NT 4.590 KG"

so When I press "Print Button" On the Indicator its Sent :

1) US,NT --- DataReceived Firing ,
2) Space --- DataReceived Firing ,
3) 4.590 --- DataReceived Firing ,
4) Space --- DataReceived Firing ,
5) "\r\n" --- DataReceived Firing ,

I think It's Must Sent the Weight as a whole , ( as Other Indicators Works ! )

Any Suggest Would be Appreciated !

I know nothing , I know nothing ...

Hi,

you should use the "ReadLine" method instead since it reads the response until it receives a "NewLine" (\n).

Try:

private void serialPort1_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
   TxtOutPut.Text = serialPort1.ReadLine();
}
