• Visual Studio 2008 (Pre-release) 2 Way Binding

  I'm attempting to do a two way binding to an Listbox. Each list box item contains several items.

• Visual Studio 2008 (Pre-release) DLinq query performance

  Hi! I tried to do following : created database with table Order and insert 3000 rows in it. Then, i used sqlmetal to generate stuff. Then, i queried all orders with DLlinq and same thing with sqldataadapter. I used Sql server profiler to measure the execution time.

• Visual Studio Express Editions Empty Project Template's Missing

  I know, I know, why should I care... According to this thread http://msdn2.microsoft.com/en-us/library/b4z62wxz.aspx VB Express should have the following templates built in (just like C# Express): Class Library, Console Application, Empty Project, Movie Collection Starter Kit, Screen Saver Starter Kit and Windows Application. On my system, however, the Empty Project template does show up in the C# edition, but not in VB. Why's that Probably I won't be missing a lot (hey, after all, it is an EMPTY project template), but sometimes those little things can really bother me. Oh, by the way, can I download the missing piece somewhere - just for completeness sake. And, no, it wasn't in the setup either. Thanks! ...Show All

• SQL Server CLR Enabled

  Can anyone tell me what this means and how to fix it I created a stored procedure in VS2005 and did a build.

• Visual C# C# How do I create a pointer to an array of doubles for unmanaged code

  Hello everyone. I hope that someone out there can help me.

• Visual Studio Express Editions AutoIncrementing UniqueIdentifier column in SQL databse table giving NoNullAllowedException!

  Visual Basic 2005 Express: In my SQL database table, I have a CustomerNbr column. In Database Explorer's table definition it has "UniqueIdentifier" as it's data type, and is set as the PrimaryKey.

• Visual Studio How can I handle Build and Run events?

  Hi there, I'm developing a custom package using MPF (VSSDK Sep 2006). I need to handle some usual events in VS: 1. Build - when user presses CTRL+SHIFT+B or Build command in the menu 2. Build & Run (aka F5) - when user presses F5 or Start Debugging command in the menu I want to handle these two events and ask my external compiler to just build the project or build it and if it's ok then run the compiled result.

• Visual Studio 2008 (Pre-release) How To: Create Custom Client and Service Credentials

  I read this article on MSDN, but it doesn't describe how you consume a custom ClientCredentials on the service side. I'm fairly new to WFC and am looking to create a custom ClientCredentials class that includes additional meta information about the user that can be used to determine what authority they have to perform a particular function within the service. Maybe a custom ClientCredentials class isn't the correct way to do this but I would like to make it as easy as possible for the client side of my services to just instantiate the client proxy and have it use my custom ClientCredentials so that on the service side that meta information will be available to make certain decisions about how to process the request.
