Can't Find The SQL Server Data Provider?
May 22, 2011
I'm trying to port an ASP.NET 4.0 data-driven app to a VB Express 2010 Windows Forms desktop app. The ASP.NET 4.0 app uses a SQL Server 2008 Express database and works fine. I can change/add/delete data in the db with the web app, and I can use SQL Server Management Studio to modify the database, but when I try to establish a connection to the same database with the "Add new connection" wizard in VB Express 2010, it tells me that it cannot find the SQL Server Data Provider .The SQL Server provider MUST be installed because otherwise the web app wouldn't work, right ?

I am trying to use a COM dll referenced from a vb.net project. Everything works fine when I reference the interop inside the IDE but when I publish the file in bin folder on my server I get:
Retrieving the COM class factory for component with CLSID {A440BD76-CFE1-4D46-AB1F-15F238437A3D} failed due to the following error: 80040154.
I can't register the original dll with regsvr as the server is with a hosting provider and I thought the point of interops was to be able to use old COM dlls without having to register them

if anyone had managed to configure BDP as a datasource inside Visual Studio 2008 ? I have added references etc and can query the database at runtime but I seem unable to configure it so I can add it at design time to be able to use LINQ etc, if someone has managed to do this can you let me know how as having to manually check tables etc outside of visual studio is time consuming.

I am attempting to import data in a batch from an Excel Worksheet to a Sql Server database. Everything works except for the one date field in the spreadsheet. The date returned is off by four years from the value in the spreadsheet. Example: The Excel sheet has a date 10/24/2010 14:18, but when I look at the column in my query, the date is 10/23/2006 2:18. This pattern, 4 years and 1 day earlier, is repeated for every row in the worksheet.
The Excel column comes to me as a custom type, formatted m/d/yyyy h:mm. I receive this from an outside vendor and having them change the column is not going to be my simplest solution.
For what it's worth, the relevent part of the query is:
Select [Date Created] From MyWorksheet

I have the below mentioned code in a seperate class file for establishing connection and carry out DB transactions. I have an issue where multiple connections being opened which sometime exceed the connection pool. When I stepped through the code I found that there are codes which call ConnectDB() in a loop without calling DisconnectDB(). But I expected that the condition OraConn.State = ConnectionState.Closed should handle the situation. Somehow the condition is always satisfied hence openning another set of connection. Can you suggest where am I going wrong and also what best practice can be adopted here?
[Code]...
The connection is again opened in function updData(). While I understand that it has to be closed correctly but keeping tab on every developer is not possible. Hence I want to control it directly from the connection class by using the same connection but the condition If OraConn.State = ConnectionState.
UPDATE I have put the code in UpdateDB under a Using block and removed call to ConnectDB and DisconnectDB from function like InsertData(...). It seems that the issue has been resolved. But I would like to know in case of exception will the connection remain open? and also OraConn is a public variable defined outside Using block so will it be disposed of by the GC?

I'm need of some way of finding the UNC Path of a share via a script or command line or even a custom created program. I'm trying to automate deletion of users and the setup is a bit complicated.
Home folders are set up like this:
We create a folder on a Disk on a fileserver.When this folder is created, a share is automatically created on a lower levelThen the DFS Links are set up towards the newly created share.
Now, when deleting a user, I could just delete the DFS Folder, meaning that the target folder is the one being deleted. But since it's a share, that cannot happen.

I have two databases, one on my local work computer and other on a server. Both have been created with Microsoft SQL Server 2008. I can access both of them with connection strings that contains names of the servers and some other information. However the names contain only the ip-number of the server. And I need the full name of the server and the instance created, separated with "" character. I can see them in my SQL management studio but I need to get them from VB-code.I created SqlConnection-class but it finds only the ip-addressed name. SqlSourceDataEnumerator won't do good because it finds all unnecessary server names that I don't need. How can I find the real name of the server that is specified in the connection string?
