• Visual Studio Team System TeamFoundationServer.EnsureAuthenticated() appears to hang in ASP.NET app

  I have the following code in the code-behind C# file of an ASP.NET application: TeamFoundationServer tfs = TeamFoundationServerFactory.GetServer(m_strTeamSystemServer, new UICredentialsProvider(); tfs.EnsureAuthenticated(); Works fine when in my development environment inside the Visual Studio solution. Well, the connection to tfs works anyway. I don't get prompted for credentials. The problem is when I copy the website to my deployment environment. When tfs.EnsureAuthenticated(); is called, the site just "hangs". It sits there in a loading state (this code is called in my Page_Load) forever, or at least until I got tired of waiting (5 minutes or so). Any ideas what could be the problem here Why don't I get a crede ...Show All

• Software Development for Windows Vista Where should I store Global Application data on Vista?

  I have some files which should be accessible for all users for read and write. Where should put this type of files on Vista In XP I would put it into Program Files\[MyApp] folder, but in Vista you need to have Administrator rights to write into Program Files. I thought about putting files into All Users folder, but not all users can write there. If you are using Windows Installer (which it seems you are), it's trivial to set permissions on your AppData directory by using the LockPermissions table. That avoids you having to write any ACL code at all and is the recommended way of doing things. ...Show All

• SQL Server Currency Variables?

  Starting in my control flow, I execute a data flow that populates a recordset via SQL 2005 Stored Proc. One of the columns in source table is a currency type. Back to the control flow, I have a for each container that includes an execute sql task that updates or inserts records into another table. I get precision or data type issues since I can not assign the package variable to a currency data type. The only way I can get this to work is if I convert the currency column in my data flow to a string and then cast the variable in my update/insert sql task. Any suggestions Thanks....Gary One suggestion would be to map the currency type in the recordset to a variable of type Object in the ForEach contai ...Show All

  I wat to take my program to a different computer so i put it on a USB key and took it to the computer then when i go to run it, something happened and errors come up and the program doesn't work. How to i pack it up so i can take it to a different computer and edit the code Instead of just copying the files - Do a click once deployment to CD. This will create a proper deployment setup which you can then run on other machines - one of the requirements in the deployment will be .NET 2.0 Framework so if its not on the machines it will install it.

• Visual Studio 2008 (Pre-release) Deserializing A SAML Token Received From An STS?

  Having received an RST message, an STS serializes a SAML token into the body of the RSTR message returned to the client. In that the RST and RSTR support was pulled from WCF, it would appear that the SAML token need be deserialized on the client side for caching and reuse. Documentation concerning the SamlSerializer, SecurityTokenResolver, WSSecurityTokenSerializer and SecurityContextSecurityTokenResolver classes is sparse, however, and attempts to do so consistenty result in: "The SecurityKeyIdentifier that was found in the SamlSubject cannot be resolved to a SecurityToken. The SecurityTokenResolver must contain a SecurityToken that the SecurityKeyIdentifier resolves to." Little seems to have been written concerning th ...Show All

• Visual Studio 2008 (Pre-release) Duplex messaging to COM client

  We have a service that uses duplex messaging to provide a callback to the client, which is currently a VB program. However, we are unable to get the callback to the client as there seems to be no way to pass the clients InstanceContext to the service in the GetObject argument that's used get the proxy for the service in the VB code, e.g. Dim searching As SearchingServiceProxy Set searching = GetObject("service:address=net.tcp://localhost:8000/SearchingService, binding=netTcpBinding") searching.StartSearch "SomeSearchString" The call to the service works fine, however the callback doesn't seem to be received by the client as the callback method is never run.
