I'm sure it will help you. Re: what is the correct use of connection to database OriginalGriff26-Nov-10 5:28 OriginalGriff 26-Nov-10 5:28  Absolutely: Open connection, query, close and dispose. Database connections are a scarce resource, do not hog them or you will make your DB admin very annoyed... Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Re: what is the correct use of connection to database RobCroll26-Nov-10 5:40 RobCroll 26-Nov-10 5:40  It's best to open and close connections on the fly. Under the covers, .NET manages a pool of connections so opening and closing connections is cheap and managed for free. You can take control of this pool if you want.

Re: what is the correct use of connection to database Dr.Walt Fair, PE26-Nov-10 16:30 Dr.Walt Fair, PE 26-Nov-10 16:30  My rule of thumb is to leave a connection open the shortest time possible. Open, query, update, close. CQ de W5ALT Walt Fair, Jr., P. E.

Many Thanks, Phil Re: Running PSexec within C# Luc Pattyn26-Nov-10 3:49 Luc Pattyn 26-Nov-10 3:49  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.

Re: Running PSexec within C# Philip Lane30-Nov-10 3:16 Philip Lane 30-Nov-10 3:16  Hi Luc, thanks for your speedy reply.... it still doesn't work! 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! many thanks, Phil Re: Running PSexec within C# Luc Pattyn30-Nov-10 3:34 Luc Pattyn 30-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?

Re: What is my IP?? harold aptroot26-Nov-10 2:45 harold aptroot 26-Nov-10 2:45  Yes, there is a way, you could ask your NAT device what its (and therefore also your) public IP address is.

Re: What is my IP?? monstale26-Nov-10 2:52 monstale 26-Nov-10 2:52  Hi, you could use UPnP of your router bye Re: What is my IP?? harold aptroot26-Nov-10 2:54 harold aptroot 26-Nov-10 2:54  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) Re: What is my IP?? Richard MacCutchan26-Nov-10 2:52 Richard MacCutchan 26-Nov-10 2:52  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 Re: What is my IP?? Luc Pattyn26-Nov-10 2:54 Luc Pattyn 26-Nov-10 2:54  IMO the only reliable way is by asking the external world. Here[^] is one of many sites that may help.
