Customize Content Of XML Files (Not Network/Internet Related)
Jun 12, 2009
Developing an installer for an application, that runs based on parameters set in an XML file.
The initial install of the XML is in a template style (generic time for running app, generic settings), but via the Forms, I want to be able to have the user modify some of those parameters -say choosing time for the app to run- and then have the form write (Replace really) that data in the XML file.
Looking for some ideas as to how to approach this, as soon as I can catch on I will be able to do the rest on my own.

There's a PHP link www.domain.com/a2.php which when on a form submission shows the values again to confirm , So here we'll be hitting the submit button two times.Now the problem here is , I sent the first POST request to the server and submit the form successfully and then i captured the POST request which is sent second time where it says to confirm your form , There i found some new things in the POST header , ID and A which i can't find in the source page because The source of the new CONFIRM values page is same like the previous one and the link is also the same , I tried inspecting the element using the Google Chrome option , I found the desired lines which i wanted to get using the HTTPREQUEST method.

I've been looking for a way to do this for like two days now, and no luck.
What I want to do is get into the temporary internet files, find a certain file....
(^^^ I can do that just fine (using specialfolders, etc) ^^^)
and get the internet address associated with it.
See the attachment if you don't get my meaning.

I am working on a project using VS2010 SQL2008 and I saw an ODD behaviour , First let me tell you that the app runs without any problem in my developing pc (Windows Xp sp3 32bit)But when I was trying the application in another pc (Windows 7 32bit)I got this exception: A network-related or instance-specific error occured while establishing a connection to SQL server.The server was not found or was not accessible.Verfiy that the instance name is correct and that SQl server is configured to allow remote connections.
Now what is weird in this exception; Is when the application reaches the DataAdpater.Fill(dataset) line I got this exception but when the app reaches the DataAdpter.Insert(....) It runs without any problem .
And what is more weird is that I noticed that the dataset that is used in the previous insert procedure can later be filled with dataAdapter.Fill(...) procedure which it was giving me an exception before .
I tried these things as a solution:
1)Checked SQlBrowser running..
2)No aliases to Sql server at all to remove...
3)remote area connection--OK
4)TCP and UDP port 1433,1434 exception in firewall
5)Unistalled my only antivirus Norton
6)Added Tcp/IP ports in Sql protocols
7)My connection String is : onnectionString="Data Source=ALISQLEXPRESS;Initial Catalog=PALMSDATABASE;Integrated Security=True"
8)Also tried using Sql Server authentication (user Id and password)
what is the difference between fill and insert? My app. runs smoothly on the original pc ,What should I do?

Error message receiving A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) The project is written in VB.Net 2008. Production server uses SQL 2008, Dev Server uses SQL 2000. The application has been built and published.
Prod Connection String: strCN = "server=SGMAGNCPQ03.;Initial Catalog=APO_Tax;Integrated Security=True"
Dev Connection String: strCN = "server=S04423711940995.;Initial Catalog=APO_Tax;Integrated Security=True"
The Problem: When I change the connect string from dev back to prod and try to run my app, I get the above error message. If I reboot everything works fine but if I switch the connect string from prod to dev and try to go back to prod, I'm back to the same problem.

This is the work of one responder for the most part, and is not indicative of the quality of most of the posts.But you can judge that for yourself.
If you are writing a program that is used to monitor the status of your network, then this thread may not be of interest.
If you are an application programmer that uses network resources to accomplish your goal, i.e. you are using SMTP, FTP, HTTP, NNTP, NTP etc., and you think that you need to check for a connection first, then read on.Follow up to this.Before getting all geeky let's take a little detour...
Five days a week I get up, eat breakfast, check my email, forums, etc., take a shower, get dressed, and then drive to school.Many of you probably have a similar routine.What is interesting about that is not what we do, but what we dont do,because of our expectations and experience.Here is what I dont do.
I dont stick my finger in the electrical socket to see if there is electricity for the coffee maker and toaster.I dont fire up the command prompt and ping some host on the internet to see if I have connectivity.I dont check the battery, tires, water level, clutch fluid level, washer fluid level, etc.,before I drive off.
All of that is based on expectation and experience.So why would you write an application that pings the internet before it did something (SMTP, FTP, HTTP, NNTP, NTP etc)???? Is your experience or expectation that the network will be down?To illustrate and hopefully convince you that, like Oblio, it is pointless, create a new form with three buttons. In the following examples I use a WebRequest / WebResponse as my 'Something'.Here is what some think is a good approach, the classic ping-then-do, what I think you shouldn't do.[code]....What is wrong with this code is that all of the network IO is being done without a Try / Catch block.

Using the code below i will get all network interfaces wich are enabled and functional on the machine.
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
For i As Integer = 0 To netIntrfc.Length - 1
If netIntrfc(i).OperationalStatus = OperationalStatus.Up Then
[code]....
But my problem is how to get the default one, the one(ethernet adapter) through wich user is connected to internet?I need to change some settings of default(through wich user is connected to internet) adapter. settings i change through registry so i could sample add same settings for each network interface but that could cause problems and makes no point then?
EDITED:for now i have done like code below, so if this can help someone other...
Dim u As UdpClient = New UdpClient(System.Net.Dns.GetHostName, 1)
Dim localAddr As IPAddress = CType(u.Client.LocalEndPoint, IPEndPoint).Address
Private netIntrfc As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
[code]....

what methods use to update the main exe and related files in the app dir?
im using a seperate exe which runs with admin priviledge which downloads and replaces files as necessary.
my app downloads a text file and checks the version in that. if newer than settings.version then it runs the updator.exe and then closes.
the file downloaded also contains links to all new updates. the updator reads from this file then downloads as neccessary. then deletes the file and closes

I've been working on my game for a while, in a non-online multi-player state it is complete. My goal is to add LAN or Internet Play support.My game is coded in Microsoft Visual Basic 2010 Express, It relies heavily on timers.Currently you play against the AI, and there is a Local multiplayer mode, using mice, controllers or the keyboard.At the moment, it is a two player, (Or 1 player against the AI) game, from my understanding the standard Client-to-Server option wouldn't very efficent, the best choice would be a peer-to-peer system.That being said, a lot of the stuff could be done client side, like for instance, the particle engine and Dynamic Rendering.[code]

i want to specify a folder and then have all files from "Temporary Internet Files" copied in to the specified location. I have specified both locations, and yet it fails. I think this could be caused by the fac that the "Temporary Internet Files" is located within a hidden file/s How should i go about copying the directory?

I'm trying to setup sort of a LAN keep-alive proxy...Ex.: My Xbox 360 is connected strait to my computer via an ethernet cable. My computer is connected to the internet via a Wi-Fi adapter. Everything works fine and I can access the internet on the Xbox and computer.
Issue: Every time I start my Xbox I have to set up a "Home or Small Office Network" via the control panel to access the internet. What I would like to do is implement a proxy that when I shutdown the Xbox the LAN doesn't give the "Network Cable Unplugged" notification. I wasn't sure if there was a way to make the connection stay open for so long after it should say unplugged. Such as if I need to restart the system and don't want to have to re-setup the network on the computer.
This is my code to retrieve the network info:
Imports System.Net
Imports System.Net.NetworkInformation
Module Module1

I need to create an application (or find one application) that copies files from a computer to another, across the internet to create automatic backups. The target computer is a company server to which i have phisical access. The "source" computer(s) (several computers in several clients, that we - company, have also phisical acess). Solutions like teamviewer, PcAnywhere,... just don't fit because we already use them but they don't allow to create automatic backups. how can i copy files across the internet, using VB .NET, from one computer to another?

I am trying to make file transfer program in vb.net 2008 for big files eg. 10 GB.i was able to code simple socket program to transfer files with small size by using Sockets but if the file is large then "File.ReadAllBytes(ComboBox1.Text)" command will not work cause it use lot of memory & if the file is really big i.e. 10 GB it give not enough memory error, so i made a loop that sends data in small amounts, but this give me a larger file size with repeated data at end of the file.
