• Visual Studio Express Editions VB2005 hangs up on every action

  Hello again. I restored a backup of winxp a week ago (because windows took 5 minutes to startup, currently its under 30seconds) OK, I had to install most applications again (such as games etc.) And vb, too. I installed correctly, everything looked good. Till i started vb. I created a "New Project" and wanted to open the "Form1.vb", but what happened Right, an error message appeared with the following content...

• .NET Development NegotiateStream Class and SOAP Web Services?

  Hi, I just heard about the NegotiateStream Class and I’m wondering if I can use it to protect traffic on the wire between my client (.net winforms app) and server (.net web service) Right now I’m using SSL, leveraging the built in support that IIS offers, but since my app only runs on the intranet I’m wondering if NegotiateStream would make more sense. SSL works fine when you get it set up, but there is quite a bit of overhead when my customers first deploy (e.g. issuing certs, configuring IIS, making sure that clients trust the right CA etc.). Thanks. Yes Negotiate Stream encryts the data ...Show All

• Visual Studio Team System How to set permissions to a field in a workitem.

• SQL Server Execution Plan Object Notation

  Is there a way to remove the database name and ".dbo" from the object name in the execution plan I almost never do a cross database join, and all tables are owned by dbo. Since there is limited room, I'd much rather see the full table name and index being used. Also, does anyone know why the lines (representing the flow of data) don't represent the actual size of data moving around I'd think that actual rows returned x estimated row size would determine the thickness of the line, but there doesn't appear to be and rhyme or reason to the line thickness. It's too bad, since I used to use this information in SQL 2000 all the time. ...Show All

• Visual Studio 2008 (Pre-release) Passthrough of ASP.NET identity to WCF service layer.

  I have a WCF service hosted in IIS, and an ASP.NET application that consumes it. I need to provide user-based security at both the application and service level, and so I'm trying to propogate the ASP.NET user through to the WCF service. I need to be able to do this for both Windows and Web-Forms authenticated users, but I figured Windows would be the easier win to start with. My binding is currently wsHttpBinding, and I've tried both Transport and Message security using Windows credentials. I've also tried using [OperationBehavior(Impersonation=ImpersonationOption.Required)] on my service to no avail. All I ever see is my IIS user bei ...Show All

• Visual Studio Remote Web Access over http in VSS 2005

  I am currently evaluating VSS 2005 beta and have been advised by MicroSoft Customer Services that the 'remote web access over http' feature is available in VSS 2005 as a standalone product and it is not necessary to have Visual Studio installed.  However, I am unable to determine how to connect remotely. I have installed VSS 2005 Beta on a server and created a SourceSafe Database on the same server, which I can obviously easily open.  If I am working in the office on another machine, I can easily connect to the VSS database on the server, by specifying the path, as with VSS 6.0.  However ...Show All
