View 6 Repliesi 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:

View 1 Replieswe have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.

I am trying connect to a SQL Server database i have created using Visual Basic.Both reside on my local machine (PAUL-PC).Here is what i have done so far but i am missing something (or more worryingly i have got it completely wrong).[code]So i have an MDI form and i want to make a connection to SQL Server when that form loads.I do not want to use a DSN if possible so am trying to use Oledb. Not sure also of the DataAdaptor declaration as in previous versions i used many years ago it was recordset.I would like to use a trusted connection to connect.
View 5 RepliesWe have developed a VB 2008 app that uses SQL Server 2005 Express to store data collected by this app. This app has been designed to allow multiple connections to the one centralized database.
I have ran a few tests, and confirmed that if one computer running our app is accessing a database residing on a different computer,and the network connection between two computers has been severed, it would take approximately 3.5 minutes before I would get a connection timed out exception error from within my code.
I have deliberately set the ConnectTimeout property in the SQL connection string to be 15 seconds. But some how, SQL database engine still retries until approx. 3.5 minutes later.
My thinking is that I have a subroutine that would attempt to open a database once a minute.If the open attempt is not successful, and resulted in an exception, then I would popup a message to notify the user that the connection is not available.
Doing it this way, I have confirmed that it would take about 1.5 minutes for it to re-establish the connection, once the actual network connection has been restored.
To make the long story short, I would like to find a way to shorten the detection for a broken connection, and let the user know sooner, rather than locking up the app during the 3.5 minutes period has elapsed, and at the mercy of the SQL database engine to timeout. And why would it take 3.5 minutes to timeout the connection attempt when I had explicitly use 15 seconds in my connection string?

View 9 RepliesI've been doing a self studies on visual basic and I thought I've learned a lot but still I realized that I still have something more to learn. I want to learn the basic fundamentals on SQL for its database operations such as adding,editing, and deleting records. I would say I'm new to SQL because as far as I've used VB, I've been using LINQ(Language Integrated Queries) for database operation. I've been doing a lot of research online on how to start and connect to SQL but I find hard to make it on my own cause all I've got is an error during runtime.

Would like to know if it is possible to access a Primavera 6.2.1 database (.mdf) from VB 2008 Express. Would like to take advantage of the existing database, if possible.

View 16 RepliesI have a problem using my database in which I have a table with product names, codes, prices and information. I use the below method to get connected to my database and tables.
Dim dtCOP As New AmetailorDataSet.COPDataTable
Dim adapterCOP As New AmetailorDataSetTableAdapters.COPTableAdapter
adapterCOP.Fill(dtCOP)
But in one row, I have product descriptions so there should be sentences. I set the type of this row is Text in the database. When I use single numbers in the table, there is no problem. But if I write sentences (that is a must because it is product description) or even a single word, I get the below error on adapterCOP.Fill(dtCOP):
"Input string was not in a correct format.Couldn't store <(the written text in description)> in Description Column. Expected type is Decimal."
There is a richtextbox in my form that should show the product description when the product code is selected from a listbox available in my form.
