ADO.NET does not have recordsets. Classic ADO does. You should be using ADO.NET. This may be an incompatibility issue.

As Colin said, you should be using ADO.NET, not classic ADO. The reason your recordsets are not being disposed is that they are not managed objects, but wrappers around COM objects (whose lifetime you must manage yourself). ADO.NET is supported by the System.Data.Oledb namespace in .NET.

What do u mean by recordset here. Is it traditional recordset of ADO or u r talking abt DataReader of ADO.Net.
Plz give the details of "Data" or atleast "Data.Get_TAccount"

PASCAL? Do you mean Delphi or TurboPASCAL? In tp it is imho impossible. With Delphi Prof you can use Access-DBs with die ADO-components.

No, you can't do this. If you want to use PASCAL buy Delphi 2006 or if you prefer PASCAL for .NET u should buy VS2005 >= standard (standard, prof, team suite) and Chrome 1.5[^].

Isn't that what the query optimiser in SQL Server already does?

Could you elaborate on what you need? Mr. Mackay's advise is probably the best. Only other optimization tool that could work, according to Michael Abrash's Zen of Code Optimization, is right between your ears

No problem about opinion, which we all are entitled to as humans. However, be careful about trying to teach someone about professionalism when you wrote:

I guess if this does not say it all then I am asking the wrong people.
But since I've googled and Dave googled and no results came up that sounds like what you are looking for, then maybe you could come up with a tool that suits your requirements and share with your fellow IT professionals (whether it be by FEE or FREE).
Happy coding

After Googling for this for about 30 minutes, what you want doesn't exist.
All I found were tools that do the same thing that the Analyzer does in 2005.

Dave,
I found the same thing too. Google is often a great place to find things, if it can't be googled, then it may not exist. I often see google like the "Jedi Archives" from Star Wars where the jedi librarian tells Obi-Wan Kenobi that if it isn't in the archives, it probably doesn't exist. 5 points for your post

I have a table with two columns named IdHorse and IdRider.
How can i prevent the table of having more then one horse with the same IdHorse. Can i do that in the INSERT INTO statement ore alter the table somehow
|

The detail you supply is a little vague. Here is my understanding and assumptions:
There is a table with two columns
IdHorse
IdRider
[Assumption] There is only to be one IdHorse in the table. It identifies the horse, therefore it is the primary key.
Solution: Make IdHorse the primary key. It will enforce uniqueness.
However, from the way you described it, I have a feeling there is some missing information somewhere which would invalidate my assumption and therefore the solution.

Hello,
I am having a problem with specifying DSN in the SqlConnection object's connection string. How can I specify DSN for SqlConnection string. (Can I specify it at all?)
Thanks in advance.

Personally, I prefer to access all data through stored procedures as this adds some extra protection in my application as I can revoke the access to the tables which means that if anyone gains access they can only do what the stored procedures petmit them, rather than have unfettered access to the tables directly.
Views kind of come in the same category as they allow the actual tables to be hidden behind the façade of the view.
There are not really any advantages or disadvatages either way. It depends on how you prefer to work. If the calculation is simple enough then a view will be fine.
However, if you require to filter the rows at any point then a stored procedure may be better as you can filter early and this sometimes helps the query optimiser find a better plan.

Can someone help me with this one i have writen a function that retrieves a Id from a table but the result is not found and i get the above error.
Public Function getID(ByVal strTable As String, ByVal strValue As String) As String
Try
Dim IDConn As SqlConnection = New SqlConnection("server=localhost;uid=sa;pwd=;database=EventMngt")
Dim IDString As String = "SELECT Id FROM Boekelo_Horses WHERE Horse_Passport = '" & strValue & "'"
If strTable = "Boekelo_Riders" Then
IDString = "SELECT * FROM Boekelo_Riders WHERE Rider_FEIId = '" & strValue & "'"
End If
Dim IdCommand As New SqlCommand(IDString, IDConn)
IDConn.Open()
Dim IDReader As SqlDataReader = IdCommand.ExecuteReader()
IDReader.Read()
getID = IDReader.GetString(0)
IDConn.Close()
Catch ex As Exception
MessageLabel.Text = strValue & " is not on the DataFile, try again.<br>Error text:" & ex.Message
getID = "-error-"
End Try
End Function
If i comment out the getID = IDRea... line then the function returns no error, if in the function it produces a error. But why??

If there is no result then what can it cast to a string?
You need to check if the result is null first, then get the value (if it exists).
Use:
IDReader.IsDBNull(0) to determine if the value is null before trying to get an actual string value.
See Also: SqlDataReader.IsDBNull()[^]

I replaced some code to check on it but no result.
Dim IDReader As SqlDataReader = IdCommand.ExecuteReader()
IDReader.Read()
If Not IDReader.IsDBNull(0) Then
getID = IDReader.GetString(0)
Else
MessageLabel.Text = strValue & " is not on the DataFile."
getID = "-nodata-"
End If

O stupid me, i found the problem.
Tryed to get a Id field that is autonumbering i forgot that that colomn is not a string but a Int32 value. After changing that it works
