List Available Sql Server Instances (default & Named)
Oct 6, 2008
I would like to get a list of sql server instances on a computer but need both default and named instances.In the post: [URL] the code works perfectly for finding the default instance of SQL Server but it doesn't show other running instances (named instances). On my development computer, SQL Server Express, SQL Server 2005 (both named instances) and SQL Server 2008 (default) are all running but express and 2005 don't appear in the combobox dropdown list.

I currently have a sofware with 80 customers.All share the same database structure, when data are differents.We got 5 database for each customer.Today, we have named instances, so the program is accessing to Bdd with something like :
Connect to 127.0.0.1/CUSTOMER1
select * from base1..table1
Now, we need to change, we got many instances.The idea is to have unique SQLSERVER instance, obviously i want to avoid changing the code (VB.NET).Just tried to play with schemas and users, seems to be an option, but since the schema is under the database, in can't make it works :
Connect to 127.0.0.1/GLOBAL_INSTANCE as specific user (customer1)
select * from base1..table1 -> error @ this point
When THIS works :
Connect to 127.0.0.1/GLOBAL_INSTANCE as specific user (customer1)
Use Base1
select * from base1..table1 / or select * from table1
I can easily script some user or schema creation, and change connection strings for all customers, but i can't really change All requests: huge number.

I believe one or more versions of VB.Net did away with "default instances" for Forms.
1) Was it in the 2003 or 2005 version(s)?
2) With the more recent 2008 and 2010 verions, is it possible to use a template or
change one of the files in the project so that default Form instances are not created?
I was recently looking at some of the other .Vb files in VB.Net 2008 Express Edition.
By the way, just so you know I could install a full version of Visual Studio if need be from;
2203, 2005, 2008 or 2010

I'm using Visual Studio 2008 writing a Windows Forms project and I'd like to know a way to step around 'default instances' of forms. I don't like default instances, they constantly get in my way, and working in a team it's causing some really annoying confusion about the object identity of which form is actual in focus at this moment. This means I need to go threw the entire project (big) and remove ALL references to any 'default instance' of a form. But this is difficult to do as there's no errors or anything, it basically requires me to search for every text of "MyFormType." and then checking if it's accessing a default instance and fix it like that.
It'd be nice if I could just turn it off or something so I could
1) easily find all erroneous lines of code
2) avoid the accidental use of it in the future by anyone on the team

I am trying to connect to SQL Server 2008 from my windows application using vb.net through named pipes.
I did some browsing and I found, to connect through named pipes we just have to mention "Initial Catalog =Test_DB; Data Source = np:Server_Name;integrated security=SSPI;".
But this doesn't connect to the server at all. Is this the right way to connect to sql sererver using named pipes?

The client/server communication will only take place in the same network.I can use TCP, but then I have to configure separate IP ports for every server instance. I can however simply use named pipes so I don't have to think about port numbers and simply use the name of the server instance.There will not be very frequent and/or large data client/server communication. It's some sort of a ERP application that will only communicate once per 30 seconds on average.

I am writing a VB.net client to write to and read from a named pipe in byte transmission mode.I learned from the MSDN article that CallNamedPipe() only works for message-type named pipes.
So do I have other choices, or do I have to change the pipe server code to message type.

I have an exe that runs from the server. The instances are shown on the server. So the questionis how can I get the following code to count the instances on the server.
HTML
Dim oProcess As Process
Dim nCount As Integer = 0
For Each oProcess In System.Diagnostics.Process.GetProcessesByName("MSTP")
nCount = nCount + 1
Next
(MSTP is the name of the application's exe.)

I have a .NET class, InstrumentConnector, that has an event, StatusChanged. I want to create several instances of this class (each class handles a separate file) and respond when the StatusChanged event is raised any instance. How would I do this in .NET? Do I want to create a List(Of InstrumentConnector) or a similar IEnumerable? How do I write the event handler to respond to a particular instance's StatusChanged event?
Here is the InstrumentConnector class and the module with the StatusChanged handler:
Public Class InstrumentConnector
Private _inProcessDir As String
Private _doneDir As String

I have created a simple windows forms application. I would like to be able to connect to that running application and view certain properties from a seperate windows form application. In VB6 I would have run the first application and then called GetObject to connect to the instance. Does anybody know how I could do this in .Net. I'm guessing I'd have to use reflection to get a list of applications running and then somehow connect to them but I'm not sure how to do this?

A while ago, I wrote a web-based guestbook application that wrote it's own database.
My code was very amateurish, but, as it was my very first publication, I was very happy with it. Only about a month after I'd published it did I realize I'd made a huge mistake in the code.
I've only ever connected to a specific named instance of SQL Server, and it occurred to me that, if the SQL Server instance has a different name than the one I specified, it wouldn't work.
So, since my users will probably not know what the name of the instance of SQL Server that's running is, I thought adding a field where the user can specify it would help if they do, but what if they don't? My answer was to get the local instance, regardless of name.
I tried Data Source=.local;, Data Source=.; and other variants, but nothing worked.

In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

I am not too sure about the syntax , since I am still very new to VB..
So this is what I have in a class
Code:Public Class DocumentDelivery Implements IDisposable Public Shared RenderList As New List(Of Byte()())
Public Function Initialize(ByRef env As et.User.SystemCommon.Environment, ByRef errs As et.Exec.Utilities.ErrorCollection) As Boolean
[Code]...
I didn't write the existing class, I am just making changes to it. I am not sure why there is no constructor. However, Intialize() is called every time a the class is created.Right now, I set the default capacity of the RenderList, (the class variable) to 1 in Initialize method.
Is there a way to set the capacity outside of the initialize method? what is the syntax?

Just as the title states, can anyone point me to a list of all available asp.net server controls (preferably with descriptions)? I would have thought that something like this would be readily available but I've had no luck finding this. I almost always have to dig around to find a control to solve a particular problem, a quick reference would be really handy.

I got no errors in the code now, but it doesn't seem to work. The only thing that works is when I try to list all the data.But when I try to narrow the data that is to be listed. I get no good results. Here is my code:
If ComboBox1.SelectedItem = "School" Then
Dim connectionString As String = "Data Source=SENBONZAKURASQLEXPRESS;Initial Catalog=testing;User ID=SenbonZakuraRew; Trusted_Connection=True;"
Dim selectCommand As String
[code]....
The code above is not the whole thing. I've omitted those that are not relevant. What do I do to make this work?
