So basicaly when you click a record, if the grade is 5 i want the radiobutton5 to be selected. And if i click radiobutton6 it should update the field to 6.

I am using VB 2008 express and SQL Server 2008 express on a test basis and I used to connect VB express to a SQL database (created in SQL Server 2008 Express management studio) file and it work perfectly until my hard drive packed up and I had to get a new one, so I had to reinstall both of these again and copied my old databases from a backup I had. Now when I try to connect to the database file it cannot connect. Network related error or the instance name is incorrect. When I look at the advanced options in the connect dialog it shows my instance as .SQLExpress and my correct instance name is .SQL2008Express. I clicked OK on the connect dialog and manually changed my connection string to the correct instance and that worked but whenever I run the application in debug mode it give me the same error as above.

View 1 RepliesI added a new database using SQL Server Management studio express 2008. I can connect to that database using Web Developer and Visual Studio just fine. But when I try to connect from VB Express 2008 I get an error message "file in use by another program". VB only prompts me for the name of the database, but Web Developer and Visual Studio prompts me for both server instance and database name. I'm sure this is just something simple I'm missing.

Basically, it doesn't work and I don't get it. I've been trying to figure this out for a few days now and I can't see what I've done wrong. As you can see I'm trying to manually update a field in my database with the value of (originalvalue)+1 when the user clicks the buttonfield of the corresponding row.
I guess what I'm asking is if anyone can point out any mistakes, please do, or if there's a better way to do this (without having to go through all the DAL/BLL BS)

So, what I'm trying to do is to connect to a remote database using the MySQL connector. Dim c As New MySqlConnection c.ConnectionString = "Server=" & URL & ";Database=" & "" & ";Uid=root" & ";password =" & "" c.Open()I know the connection string is correct. I can access the phpMyAdmin through a web-browser just fine. For some reason however trying to open the connection throws an exception 'Unable to connect to any of the specified MySQL hosts'. I tried disabling the VS debugging process, as I thought maybe it's blocking my MySQL access for some reason, but no.

I'm building an application that is intended to function off and online using the new Local Database Cache functionality included with Visual Studio 2008. My issue however does not pertain to that directly, as I have a pretty good understanding of how to use it and how it functions. My issue is with getting an understanding on how to directly write to a SQL database.
Most of the tutorials, videos and education available when it comes to databinding makes the assumption that I need my application to pull data and edit it, but in my case all I really need (in fact intentionally all I want) is for the application on Submit to write data that it pulls from the form as a new record in a SQL table.
Here is what the program looks like now.
Public Class StatCom
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
At the moment the program simply does a status check for connectivity and wether it can ping the server (in this case the SQL server) for the purpose of displaying a online or offline status in the form.
I follow it up by making the status checks.
Finally I declare all the various fields I want to capture and write to the database.
What I want to do now is have a SUBMIT button that on click takes all the data in the form and writes a new record to the database I have already setup and have data connection to.
I know that the code has to be written using the .recordset functionality, but I haven't found any could tutorials on the subject that have turned on the light upstairs.
I have been learning about working with databases and VB. I have coded the connection string for a MS Access database to my VB project but i cannot establish a connection with my sql mdf database.
