OK, here is my programming attempt:
Imports System.Data.SqlClient
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sqlConnection As New System.Data.SqlClient.SqlConnection("Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\patient.mdf;Integrated Security=True;User Instance=True")
Dim command As New System.Data.SqlClient.SqlCommand
command.CommandText = "ALTER TABLE Patient ADD CaseNbr Varchar(50)')"
sqlConnection.Open()
command.ExecuteNonQuery()
sqlConnection.Close()
End Sub
End Class
I got the following error when I executed:
An attempt to attach an auto-named database for file C:\Documents and Settings\Owner\My Documents\Visual Studio 2005\Projects\Add Column\Add Column\bin\Debug\patient.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

Here is another attempt:
Imports System.Data.OleDb
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim Sql As String = "ALTER TABLE Patient ADD CaseNbr Varchar(50)"
Using connection As New OleDbConnection("Data Source=.\SQLEXPRESS;Provider=SQLOLEDB;AttachDbFilename=|DataDirectory|\Patient.mdf;Integrated Security=True;User Instance=True")
Using command As New OleDbCommand(Sql, connection)
connection.Open()
command.ExecuteNonQuery()
connection.Close()
End Using
End Using
End Sub
End Class
It aborted with the following message:
No error message available, result code: DB_E_ERRORSOCCURRED(0x80040E21).

The connection string is wrong. You haven't told it what the database name is. Without that, it'll try to attach the same database file again, resulting in the error you got.
Driver={SQL Native Client};Server=.\SQLExpress;AttachDbFilename=|DataDirectory|mydbfile.mdf;Database=dbname;Trusted_Connection=Yes;

I ran the above code as a separate project.
Now, when I attempt to run my main application, it bombs out immediately with this same error!
An attempt to attach an auto-named database for file C:\Documents and Settings\Owner\My Documents\Visual Studio 2005\Projects\Add Column\Add Column\bin\Debug\patient.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

Hello,
I want to show database information in a listbox using a SELECT query.
Something like:
lstGeselecteerdeagenten.Items.AddRange(daGroepAgent.SelectCommand(SELECT * FROM daGroepAgent))
??????????
|
|
|
|
|
You're going to have to seperate this. At least until the new version of VB.NET comes out.
Create a method that queries the database for the fields you want in the ListBox and returns it in DataTable. Then bind the ListBox to the DataTable and your done. There's no reason to use the Items.Add method.

Error 1 Column, parameter, or variable #1: Cannot find data type GL_Record. Clrtest
Microsoft.SqlServer.Server.SqlProcedure()
Public Shared Sub sbSetupGLProbe(ByVal Selections As StoredProcedures.GL_Record)
On Error GoTo Err_sbSetupGLProbe
sbBuildGLQuery(Selections)
Exit_sbSetupGLProbe:
Exit Sub
Err_sbSetupGLProbe:
MsgBox(Err.Description)
Resume Exit_sbSetupGLProbe
End Sub
This code will compile and deploy when the Sql Server attribute is omitted but then t_sql cannot see it.

It's saying that the type GLRecord doesn't exist, at least not in the StoredProcedures class or namespace.
Why are you using "On Error Goto" when it's been deprecated by Try/Catch?

What attribute? Let see the definition as it's supposed to be written.

On Error is being used because this is a conversion of small modules which may be later converted to try catch

Create a user control that contains the 'graph' and the flowlayoutpanel. Then just add the user control during runtime.

Run aspnet_regiis from your .NET folder, sounds like ASP.NET in not installed. Reinstalling IIS would certainly mean you'd need to do this, before it would work again.
