DataContext.Log and Windows Phone

  Among the many features that are compatible between Linq To SQL on desktop Windows and on Windows Phone is the support for capturing all of the generated SQL as it is being sent to the database. This can be a great way to both gain an understanding of how L2S works, as well as…

This is the team responsible for delivering: The overall application model for windows phone (how are they installed, secured and activated) Runtime integration (hosting of Silverlight Mobile and XNA applications within NetCF) Phone specific frameworks (ex:…

RS PowerShell Gems – The WMI Provider

For IT administration of a Report Server instance, you will occasionally need to use WMI.  We try to ease this to some extent by exposing a command line tool rsconfig.exe as well as the RS Configuration Tool UI. That said, sometimes you just need to talk to WMI directly – and for that PowerShell is…

RunningJobContext.IsClientConnected

I’ve seen a few people get confused over what this error message in the Reporting Services log file indicates. This message is generated when the Reporting Services web server detects that an HTTP request has experienced a remote disconnect.  In practice, this means that we queried the property HttpResponse.IsClientConnected and it returned false. So how…

Hiding parameter area when viewing reports

When rendering reports, oftentimes the application would like to minimize as much of the non-report area of the viewer control as possible.  This is easily accomplished when rendering the report through the built-in report viewer control hosted in the ReportServer web site (http://servername/reportserver).  There are two parameters which control the rendering of the viewer control…

Hiding Rendering Extensions

Avoid using HttpContext in your reports

On one of our internal mailing lists, someone was asking trying to retrieve some HTTP Headers that their internal application was submitting to the Report Server within the report.  Someone else responded with a code snippet containing the custom code that you can put into an RDL expression to do just that.  This is a…

Scaling out the Viewer Control and rsExecutionNotFound

One of the criteria that the report server uses to match the provided SessionID with a stored report is that the SessionID has to be provided by the same user that initially created the session.  Usually, this is the case.  Someone browses the report in IE, they click around to paginate or expand toggles, and…

Scaling Up: SSRS 2008 vs. SSRS 2005 (spoiler: 2008 wins)

The SQL Customer Advisory Team just released a Technical Note comparing SQL Server Reporting Services 2008 vs. 2005 from a scale-up perspective.  Its good to see that a lot of the work that we did over this release focusing on performance and scalability (across the board, from the core server/processing infrastructure to specific rendering extensions) has…
