View 3 RepliesI have recently just decided to get back into learning some coding and downloaded the MS Visual Basic 2008 Express addition, and i believe this is the right forum, not vb.net.My question is how to open a connection through code to an access database.From what I remember you have to initialize the variables before the functions up top and then open the connection string somewhere. Can someone provide some basic code to open the connection between the form and the database. I am just starting out again and want to basically just populate a combo box by clicking a button, from a table in access with 5 colors.

The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well
View 8 RepliesHere is the scoop: I am trying to make a user account SQL database work with Visual Basic 2008 Express for login purposes, i.e. usernames & passwords. Plan is to host this server so people can login to use the the application and verify they have a valid account. I would like to host all the account information in SQL due to the possiblity of hundreds of users at any given time. I also need the ability to add data to the database for users registering for the first time. The SQL server will need to be able to access the SQL Server databases remote via WAN.
View 1 RepliesI am an experienced programmer but am new to VB. To start, I am trying to create a simple database program. (My ultimate goal is writing a comprehensive database program in 6-8 months)I have created the database and bound the fields to a form.
But what I want to be able to do is add a field to the database and then also bind that new field to a textbox on the form.The new field appears on the list in the Server Explorer window (on my left) but not in the data sources window (on my right.) The data sources windows has a "refresh" option but that does not help.When I manually add a textbox and try going to DataBindings in the property window the new database field is not listed.
I am writing a small VB 2008 application which connects to a SQL Server 2008 database,which is hosted with Fasthosts in the UK. The connection string I am using is;"connectionString="Data Source=xxx.xxx.xxx.xxx;Initial Catalog=xxxxxxxxxx;User ID=xxxxxxxxxxx;Password=xxxxxxxxxxxx"I can connect to the remote data using the "add data source" within Visual Studio and can preview thehosted data without anyssues however when I try to run the application I get an error stating;"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)"

View 5 RepliesI want to understand the concept of connecting to a remote PC or server. I'm working on an app that will connect to a remote server.

I'm just not sure how to connect to a machine remotely if I have valid credentials. There seems to be sever ways to accomplish this. I want the most efficient way using vb2008.
