I've got a code using SQLClient that loops though all users in a Users table inside each loop i want to preform another search in the UserOrders table, thus doing a count of all orders.
I get this error
HTML
There is already an open DataReader associated with this Command which must be closed first.
Here is my code
vb.net UserLists.Items.Clear()
Dim connection As New SqlClient.SqlConnection(My.Settings.ConnectString)
Dim command As New SqlClient.SqlCommand("SELECT * FROM Users ORDER BY PersonName",
[CODE]...

I have a simple Windows Service that reads from an Excel spreadsheet and imports the records into a SQL Server 2000 database table. Before it loads it checks if the file has been successfully imported before (using filename) and whether any of the records in the file have been imported before (using primary key). If these checks are ok I load the records into a datatable and then update the datatable to the database.
However, I need to do this in a transaction as I want to ignore the whole file if there is an error. The file goes to a discarded folder and the user gets an email with why the import failed. (This is likely to be because the store the record is for is not yet added to the database and the referential intergrity of the db fails). If there is no transaction the records before the failure record are imported. When the file is imported again (the store has been added to store table) the file is then rejected because duplicate records are already in the db.
Heres my code:

I want to authenticate each user every time. in vb 6.0 i used this
Private Sub cmdIngresar_Click()
Dim rs As New ADODB.Recordset
Dim strConsulta As String
[CODE]...
So, my question is how could i modify it for vb2005, because vb2005 don't use recordsets?

I've been googling for some VB.Net code to authenticate to a web server with the POST method, receive a session ID in a cookie, and then send this cookie along with all GET queries... but all I found is half-working code or C# code, ie. difficult to use for a VB.Net newbie.

I have a windows service application that is meant to interact with SQL server database (INSERT, UPDATE, ETC). The windows service application is also multi-threaded.I created an "App_Data " folder to keep my database and used app.config file for connection information, etc.
After installing and starting the service, nothing happens, the database doesnt get updated, etc.
Has anyone ever written a windows service application that interacts with a database? Kindly advice me on how to overcome this problem..

I've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop.I've ran the Open Current Database call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true.I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application.

I wrote an import procedure that extracts certain row data from Excel files. Currently, I manually create a DataTable in VB.NET, add columns and their datatypes. don't add anyconstraintsto the table, but the SQL database table where this data is going to does haveonstraintssuch as a column can't be null, check constraintsor unique constraints.Here is a simple example of my code.
Dim dt As New DataTable
With dt
.Add("Column1", Type.GetType("System.String"))

I hate to ask this question on this forum, but I'm having a lot of trouble finding it on these online tutorials. Basically, I'm learning about SQL, VB.NET, and how to glue the two together, and I've learned about using SqlCommand.executeScalar() to get the first entry in a table. But that's all it's really good for, right? Or is there something more to the story here?
Basically, I'm wanting to ask about how to pull in a FULL table from a SQL database while using VB.NET, as well as how to pry substrings and stuff from it. Again I'm having to ask this on this forum because all these online tutorials seem to ignore the subject completely.

I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields:
QuestionNumber (unique integer key)
QuestionText
QuestionType
In my SQL Server database I created a Table called "QUESTION" with the same fields.
QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

The above is more or less the complete question. I have created a table in the VB 2010 Database Explorer but I cannot for the life of me work out how I can get this copied or created into the underlying server. It is not appearing in the underyling serverand when I run the code of course I ge "invalid object <tablename>" I have data as well in the table that appears in Database Explorer. I think I have missed something fundamental in my overall conception of using VB 2010 Express with SQL Server Express in that I don't know if I have a local copy (that isn't then mirrored on the server), or what (the ____ have I got)? An article that explains the overall relation of Database Explorer to the underyling Server would be great as well

[Code] my issue is that now i need two cases, first i need a query that will return the date created and modified of the table and i also need to know if its possible to query a list of table names in the database ordered by date created but that have a certain thing in their names. for example the database contains the following tables: [Code] and what i need the query to return is the tables that contain "Data", settings and employees are for the other functions of the program. so the query should return the 4 data tables in order of date created. but i have no idea how to go about doing that in the query, does anyone know how this is done?

Is it feasible to deploy a VB.NET windows forms application with a SQL Server back end where no users have direct access to SQL Server? The idea is that there is no way someone at the client site with admin capabilities could mess up the data definition, or directly alter data. I always assumed that somebody with the client should get admin capabilities, but perhaps not.
The application will have to have the capability of creating logins, doing backups, perhaps running scripts (encrypted?) For upgrades, and whatever else a user with elevated privileges would do. I guess the application would have a hard-coded account with admin privileges for this purpose. Is this a common way to deploy an application? The application uses SQL Server Express, which is installed with the application. The database will be installed with the application.
