GridView - Check Each Row And Do Ping To IP Then Write Result
Jul 14, 2009I have a gridview with two cells cell(0) is a IP-number and cell(1) is a resultTxt. I have X number of rows. I want a solution that check each row and do a ping to the ip and write result to result. I want to do the ping in a new thread and i want to be able to do more then one at the time. So I want a loop that keeps checking the ones that are not online until they goes online. It's the thread-part I have questions about, looping gridview and doing a ping I can manage, but it I don't do it in a thread the interface freezes.

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.

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.

View 3 RepliesEnd Result Of Combobox Selection Keep Showing Same Multiple End Result When There Is Only One Entry?
Dec 10, 2010I am currently having a headache on how to solve this problem that i am facing. here is the situation: I have a combobox and a list box on the main form. The combobox will get the data from the ms access database. In the database, i have the details of a person's IC, Name and DOB say for eg on one entry I have D215311523C,SHAWN,13/04/1987 So now, my combobox on form load will show the list of dates in the database to allow the user to search base on the date itself by clicking on the selected date. So when the user clicks on the particular date say 13/04/1987, people in the database whose birthday is 13/04/1987 will be shown on the listbox.Meaning to say if i have 3 entries whose dates are the same 13/04/1987, 3 entries will appear. If there is only two entry, then two results will be shown. But now, when i do a single click on the date, one result will be shown. That is correct. But the problem is when i click on the same date again, three of the same results will be shown on the list box. that is it will display : 13/04/1987 13/04/1987 13/04/1987 which is not the case. Then it will show more duplicates of the same results if i click more times on the same date which should not be the case.

VS 2008 - Respond To PING Request Disconnected From Irc Server With "Excess Flood"
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

Limit Result Being Put Into DataSet And Get Next Result From Database
Apr 16, 2010I just read about DataSet in VB.NET, it uses disconnected concept. My question is: if my apps has "List All" button that query data from 1 table in the database, and that table has "very very very" many rows, so my DataSet will be filled with those data and eat up memory. Can I limit the data that being put to the DataSet from that query? But I want to be able to retrieve the next data from the same query if the user want to see it?
For example:
I have 1000 rows in my database, and i query all of them. But I just want 200 rows being inserted to my DataSet, but if the user want to see rows number 201 and so on, I want to be able to retrieve the next 200 rows, and so on. So it just like cutting those data into a group of 200 rows. Can I do this with the concept of "disconnected" of the DataSet?
