Feb 10, 2010i need to know what will it take for me to access, insert, update and delete data to a database on a remote SQL Server. I already made some configurations to the SQL Server 2005 that I want to access by following the steps coming from this link -> [URL]. But somehow I am still getting an error. My primary concern is "What connection string should I use on my client VB.NET application to connect to the remote SQL Server?" Since I will be connecting to the SQL Server via Internet and not by LAN, I am wondering which IP Address and Port am i going to put on the 'connection string'? How can i get my 'TRUE' Ip address? Or is there any other way to go through with this? It will be very helpful if you could share your insights and knowledge. Here's my sample connection string:

Check If Connected To Internet + Image Available?
Oct 18, 2010Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

View 9 RepliesCheck Internet / Network Connection ?
Nov 19, 2011This 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.
Get An Application To Check Internet Connectivity?
Jan 10, 2012I need my application to check for internet connectivity on my user's computer. If there is, an image is displayed and if there isn't, a different image is displayed. Here's the code I used to get this to work:
Private Sub Window_Loaded(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded
If NetworkInformation.NetworkInterface.GetIsNetworkAvailable Then
Dim bi1 As New BitmapImage
[code]....
I decided to test this on my own computer by changing my default gateway (thereby making it seem as if I lost connection). But I realized that the code still showed that I was connected. So I'm thinking that it's only checking for connectivity of the interface - which in this case, is my connection to the router (which is true, I was connected to the router).How do I check that the user's PC is actually connected to the internet? I read the article Check for Internet connectivity but it's in C# and I don't understand that.

May 27, 2008i am trying to develop a multi user application. this is the first time i am doing it. my database is sql server 2005. and using vb.net as the programming language.i have few questions,
1. my database is in one computer. this computer is not actually a database server. it is just a computer. and the database is created in local drive (e:) of the computer. when i develop the application. so, if i am writing an application for the computer where the database is created. i can give the location of the database as my connection string (is there any better way to do this. because there might be problems, if the database location is changed). how can i connect to the database from the other computers in the same network?
2. this is my second question. i have a table which stores customer details (customer id is primary key and its auto number). one customer can have many hobbies. so i took it as a separate table (customer ID as the foreign key of that table) . when i enter data, i use single form to enter the customer details and their hobbies. so when i insert the record into two tables, will the second table take the new customer ID automatically into dat tables customer ID which is a foreign key.

Connecting 2005 To An Access Database?
Dec 18, 2009I want to connect to a Access Database I've tried to do it though Data Binding and that doesn't seem to be working so I'm going to have to do this through Code... every book I have tells you how to do it with SQL Server but can't find a example for Access that doesn't involve just using the databinding tool. Writing the queries isn't a issue it's just connecting to the database and then putting that data into a couple of text boxes. Lets say the database is called TestData and the table is ClientInfo and we want to put Date, First, Last into txtBox 1, 2 and 3 respectively when the form loads.
