• SQL Server Wheres the data?

  Ok, this is driving me nuts. I create a SQL database and populate the fields. I can see the fields in the grid with the data, I tell it to update and it does, at least there is a delay while it does.  Me .AddressesBindingSource.EndEdit() Numrecords = Me .AddressesTableAdapter.Update( Me .MyFirstDatabaseDataSet.Addresses) The value of Numrecords is the correct number of new fields. But, if I exit the program and come back in, the new records, or ones I deleted are not there. I was populating the table by reading information from a folder in my program. (The above statements are in the form1.closingform event.) So, I deci ...Show All

• Visual Studio Creating a Crystal Report with VB.NET and SQL Server Express 2005

  Hi there, I haven't received any replies to a question I posted, so I'll try a different approach. Can anyone point me to any resources (tutorial, walkthrough, articles) on creating a report in Crystal Reports, using VB.NET 2005 and  SQL Server Express 2005. Specifically how to set up a connection to SQL that can change. The structure/data in the SQL views/tables won't change, but the string used to connect to SQL will. I test on my laptop. When I hook up to the network, I need to switch my connection to the network SQL Server. Thanks in advance! Amber I would refer to the following Kbase article ...Show All

• Visual Studio 2008 (Pre-release) DragDelta

  Hello, I wonder why such useful future as DragDelta event is only supported by thumbs Many other FrameworkElements would benefit from having DragDelta, as otherwise we will need to implement same DargDelta as a facade on top of DragOver... Could someone shed a light on this, please Thanks. Thumb is designed to be used in the ControlTemplate of other Controls such as Slider, ScrollBar, or the ListView headers. Many controls do not use the DragDelta event and would not benefit from having it on FrameworkElement. If you need the drag events of Thumb, you should either create a new template fo ...Show All

• .NET Development Best language for using Web Services

  We are starting our first project using Web Services and I was wondering what's  the best language to use and why Thanks Hello. Depends which language your key developer(s) masters. If you have experince in Visual Basic, I would prefer VB.NET, in any other case I would use C#. Except if you have senior C++ programmers or other diverse programmers, then I would allow any combination of VB, C++ and C# (and other languages, too). Many C programmers will be more productive with C#, I think, even if it means they need to learn something new. Entry-level programmers should in my opi ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. MDX Sample code doesn't work in my Visual Studio .NET 2005

  Recently I got a new VS 2005, and downloaded DirectX SDK February 2006. I opened the DirectX Sample Browser, all the samples can be executed just fine. However after I installed these samples, let's say, EmptyProject(managed), I can build the sample code successfully, it just didn't work.

  I want to check for what programming language the current document in Visual Studio is in. I can get the currently running DTE (or technically the EnvDTE._DTE) but then cannot the language.

• SQL Server Linked Server from SQL Server 2005 (x64) to Sybase

  Hi, We have been accessing databases on ASE 12.5 (on HPUX) from MS SQL Server 2000 (x32) successfully for years. We do this via linked servers we create on MS SQL Server. When creating the linked server, we would specify the Microsoft OLE Provider for ODBC as the provider, and the data source is the name of a DSN created with the Sybase ASE ODBC driver (4.20.00.67) that points the the HPUX box on which are the Sybase databases. We have also gotten this to work just fine on MS SQL Server 2005 (x32) Standard Edition SP1. However, we cannot seem to get this to work on MS SQL Server 2005 (x64) Enterprise Edition SP1. The Microsoft OLE D ...Show All

  I'm using the Workgroup Edition of TFS in a Single Server configuration. I have VS team Suite with Team Explorer and Team Build on my client machine.

• SQL Server Shared Datasources that use dynamic DB connection strings

  Is it possible to create a shared datasource that uses a dynamic DB connection string I can't seem to get it to work. The db connection string is as such (server and DB names changed): ="Data Source=" & IIF(Hour(TimeValue(Today)) Mod 2, "FirstServer;Initial Catalog=exampleDB", "SecondServer;Initial Catalog=exampleDB") I can see why this wouldn't work as a shared datasource if I was using a report-specific parameter, but I'm just switching the server/DB based on the time. Anything special that I need to do to get this to work That's too bad... I have ~ 50 reports that need to switch between two serv ...Show All
