• .NET Development Read Records synronous (with Blocking)

  Hi! Is there any way to create an SqlDataReader which returns the Rows as they are added. It shall block until new Rows are added. Like: cmd.CommandText = "SELECT * FROM xyz WHERE Timestamp > LastTimestamp"; using(SqlDataReader r = cmd.ExecuteReader( )) { while(r.Read){ Console.WriteLine("New Row!"); } } I would like to implement a kind of Event-Notification without polling. Maybe I need a part of the logic running on the Server. This would be no problem. There must be a way to do this. The "sp_trace_getdata" System Stored Procedure works this way. And it can be used without anything unusual in ADO.Net. Any Ideas GP ...Show All

• Visual Studio 2008 (Pre-release) Security Authentication Approach

  Hi, Is it possible to do an authentication in a security session (tcp) and leave it after authenticated, but continue connected without any security I want only to secure the 'username' and 'password' and no more, so I need only to create a secure session, authenticate and leave it...but continue using the same connection ( PerSession ) without security. Many web site does it for user authentication. Regards, Alexnaldo Santos Alexnaldo, The basic authentication mode (except message anonymous client) is Message Security with Username Client. So, it is defined on binding object that is part of ServiceEndpoint of the Host. Finally, while the host is open, you can’t change the binding properties ...Show All

• Software Development for Windows Vista Information card "reset"

  I'm preparing to enable pluralsight.com to accept InfoCards, and as I do, some practical issues are coming to the surface. Here's the first :) For the multitude of websites who will accept self-issued cards, we need to consider up front what's going to happen when one of our users' machines gets trashed and they lose those their self-issued card. Even if you're a website whose security bar is so low that you can simply email the user her password, that's not going to work with an information card! Regardless of the secondary authn mechanism you're considering (if any), I'm curious to know how you're thinking of exposing this "information card reset" feature to the user. It might be a good idea to have a relatively standard way of ...Show All

• Visual Studio Tools for Office Reading an Excel range into Object(,) - 1 based?

  Hi, I've been using something I learned (probably here), but don't really understand what's going on. I read ranges into a variable with the following: Dim mValues As Object (,) = _ CType (Globals.Sheet1.Range(Cell(r1, c1), Cell(r2,c2)).Value, Object (,)) Where I use "Cell" to save typing: Private Shared Function Cell( ByVal Row As Integer , ByVal Column As Integer ) _ As Excel.Range Return CType (Globals.sheet1.Cells.Item(Row, Column), Excel.Range) End Function This works tremendously faster than reading in values cell by cell. When I do this, however, mValues becomes a 1-based array. First, I don't understand what's going on that would make that happen. Second, I didn't think you c ...Show All

• SQL Server Intellisense..when?

  This is one of the top requested feature for next version (or SP) of SQL Server. ( http://connect.microsoft.com/SQLServer/feedback  ) There si some third parity tools but light years away from Visual Studio intellisense. I have only one simple question based on this answer This is a very popular feature request. We will be working with teams across Microsoft to determine how best to do this. The intellisense offered by 3rd party ISVs is not perfect from what I've seen. This is something we're considering for a future release. Thanks for the feedback! Paul A.

• Smart Device Development How to find LPWSTR device name?

  I'm trying to programmatically turn on/off my wifi device and am following the example posted in the opennetcf forums: http://www.opennetcf.org/forums/topic.asp TOPIC_ID=4266 But the question I have is about the first argument when calling DevicePowerNotify, which is how to find out what my wifi device's name is The example above doesn't work, but if I change the name to "BKL1:" then I can control the backlight, so I think I just need to know the name of the device to get this to work. Apologies if this is a really basic question, I've looked online but haven't seen a good answer; I probably don't know enough to ask the question! Thanks! -Dana Had the same problem.

• SQL Server SQL 2000 Enterprise Linking of servers not pulling data.

  I know this is an easy one for most of you but this is new territory for me. I am trying to link a production application database to an existing SMS database. Both of these databases are SQL 2000. I have sa access to both of them. I have an accreditation application that deals with internal processes within our active directory network. We are using SMS database collections to provide the discovery for reporting of this application database and I want to compare the collection to the existing data between the 2 databases. For simplicity I will define them both. Application Database we will call “A-Database” SMS Database we will call “B-Database” I have gone into the A-Database and gone to linked Serve ...Show All
