VS 2008 - WinXP Ping Successful But Not Win7
Jan 19, 2012I have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.

VS 2008 ASYNC Ping - Writing To TextFile?
Dec 6, 2009I was trying to edit to get the reults output to a text file. I needed to do this for a few hundred IP addresses, and found kleinma's code. It works great as is, but since the number of IP addresses to ping is so large, I lose some of the info from the console session. I tried to make changes to write the information into a text file, but it doesn't output the results. I am relatively new to VB.NET, so I was wondering if you could please point out the flaw(s) in the edited code. I was trying to use the My.Computer.FileSystem.WriteAllText(File, lineContent, True) method to do this. This does export the IP address list just fine, but the results of the async ping to not get output.

View 1 RepliesVS 2008 Developing A Network / Server Ping Status App
Jan 3, 2010I work as an IT Administrator and manage a few Servers, Routers, VPN Connections over a number if locations. What I am wanting to do is create a vb.net app that will go out and ping say every 2-5mins each of the servers, routers, that are listed and then shows beside the Hostname a Green Circle which means online and if its a Red Circle its offline, and the screen refreshes if their is a problem or a device / service comes back online.
Then if its offline email a particular email address showing the hostname of either the server or router and which location saying its offline. If possible to make it easier to change the devices to show possible have a txt file or something like that with the Hostname, IP Address, Location.

Jul 13, 2009I found an example of a simple irc client, but I'm really confused about how it sends data back to the irc server. In the example, this is the code used to respond to the server's PING request. it lies in the onDataArrival event of a sockets client:[Code]
However with this simplified code, as soon as it tries to respond to the PING request it is disconnected from the irc server with the reason "Excess Flood". So I was hoping someone could explain to me the difference between the pretty complicated method and my simplified one which doesn't work.
VS 2008 - Threaded Ping - Click Another Site While Its Still Pinging Them It Doesn't Wait Before It Switches Site
Feb 9, 2010Ive got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with

Ping Using VB - Performance ?
Jul 20, 2009I have this code to ping a list of over 400 switches , the program works fine but for some reason the first time i ping all the switches alot of the attempts time-out(even tho they shouldnt) which makes the program alot slower , if i click ping again less of the attempts time-out(and as a result the program runs faster) and if i click it a third time i usually get a completely accurate result with all the switches pinging back "success" (except for a few which i know for a fact are down anyway) any ideas why this is ?

View 1 RepliesGet All Servers From AD And Ping Check?
Feb 1, 2012A little background, the client that I am working with has an enterprise AD that is a mess. They have no containers for servers or any organization what-so-ever. They also shutdown servers and did not remove them properly from AD. So I needed to come up with a program that would find all the windows server, identify them by OS, and then check to see if they would actually respond to a ping. (I am aware that this is not a perfect method if they are refusing ICMP's but its good enough for my purposes). The completion of the program will display all the information and then allow the user to save the excel workbook in a location that they choose.

View 17 RepliesHow To Ping Proxies ? Ie In IP:PORT Format
Dec 26, 2010Well I decided to try make a proxy checker, like Charion or Elite proxy checker. These programs accept large lists of proxies in the IP:PORT format, ping them tell you the response time see the screenshot of Elite Proxy Checker, im trying to make a simplified version of this program. [URL]I investigated and made my checker using Ping.SendAsync(ip, timeout, ip) method. It was only afterwards that I discovered that you can only Ping IP's using this method, not the ports as well. Ive spent a few hours trying to find the correct class/methods in order to be able to ping ports, reading different forum posts from experts they say its impossible to ping ports only IPS, can only use sockets to try open a connection with the port.
