 You need to get some beginner level book.

Gosh - you're as bad as the first guy. His code is irrelevant. He doesn't have SQL Server installed.

Well, here's some info that would have been useful hours ago. Why mention SQL Server at all, if you're not using it ?
What is the connection string you're using ? Can you open the DB using Access on this machine ?

You will need to post the connection string you are using so that we can see if the problem lies there...

To a new (VB.NET 2005) version of my application WDS I would like to add a "direct recording to MP3" feature.
WDS is about talking digital books, please see www.wds-books.com for the old VB6 version.
I looked at several commercial controls (Active Audio Record, Alvas Audio a.o.), but these seem to heavy and I fear distribution problems (dll's, regsrvr).
All I need is a simple micro to mp3-file recording feature, no choice of device or quality is necessary. Just something like:
RecordStart(filename), RecordPause(), RecordResume() and RecordStop().
Has somebody developed anything similar, or give me some hints on where to find info?
Thanks in advance for your kind reaction.

There's no mp3 encoding built into .NET, so you need an extra component to do the encoding for you. Then, if you want to do it yourself, you will need to use DirectX to do it.

Thank you Christian for your quick reply. Vielen Dank.
Extra control: I looked at three of these. Example programs do not work, or work on Vista, crash with XP. I lost lots of time in the past using controls of small firms.
I hoped to get a more detailed reaction from someone experienced in this respect, e.g. from Qualtar, who published an article on a somewhat similar LAME encoder subject.
I would like to address Qualtar directly, however, I have the impression that this is not possible(I know very little about forums).
I do not like at all your attempt to be funny at the end of your reply.
Kind regards,
Fred

For performance fill the listview, when form_load i fill first 20 records. When user click scroll down add to 21 record. Every click add to next record. How can i do this with DataReader. And how can i hand event to scroll click. Please help me. My code below;
User Control ;
Dim x As Integer
Dim dbConn As New SqlConnection("server=" + _ServerName + ";database=" + _DatabaseName + ";uid=" + _UserName + ";pwd=" + _PassWord)
Dim strQuery As String = "SELECT * FROM ListeKontrol"
dbConn.Open()
Dim myCommand As New SqlCommand(strQuery, dbConn)
Dim myReader As SqlDataReader = myCommand.ExecuteReader()
While myReader.Read And x < 20
MyBase.Items.Add("")
MyBase.Items(x).SubItems(0).Text = x.ToString
MyBase.Items(x).SubItems.Add("ListeAck")
MyBase.Items(x).SubItems.Add("Alan1")
MyBase.Items(x).SubItems.Add("Alan2")
x = x + 1
End While

This is the wrong way to go about it. If you have 500 thousand records, you need to think about it a little more than this. Your best bet is to write a stored proc that takes a page number and a number of records per page, and request the page you need every time. A dataset that you bind to makes more sense than using a loop and a datareader.

Thanks my friend, but i don't understand clearly. How get page number or some range of records with stored proc. Can I get some row index with sql.

Yes, you can get a row index, if you have an identity column and you don't delete records, you can use that.

I'm not sure what you need here, except to suggest you look into for loops. You really should buy a beginners book and work through it, the concetp of a loop is pretty starting level.

What you want to do is nasty, you should put the keys where people can find them, but I get why you'd want to hide stuff, for security, etc. Get rid of the Application. stuff and use the raw APIs that allow you to access the registry where-ever you like. There's tons of articles here and on google.
