• Windows Forms A new way of drawing the forms and controls on screen.

  The existing releases of Microsoft Windows, and the .net controls are designed to use GDI and GDI+ for drawing them self on the computer screen. As you may know, every control or form is responsible of redrawing itself when necessary, using the existing GDI libraries. Of course there are a lot of technologies involved in the process, but I will skip th ...Show All

• SQL Server Supporting Current RDL Spec

  Does Reporting Service have the concept of supporting 2003 level RDL and 2005 level RDL separately (like Excel or Word does with their various formats ) or since most changes are merely additions does the latest version of Reporting Services just consume old RDL 2003 spec files and output only the new version of the Spec RS 2005 works with the 2005/01 RDL spec. Report Designer 2005 will load old RDL files and ask you if you want to upgrade. The upgrade will convert 2003/10 elements if necessary (e.g. Custom element). Report Server 2005 will upgrade old RDL files on-the-fly when you publish them. I.e. if ...Show All

• Visual Studio Team System Missing VCOverrides.vsprops

  I've migrated to RC from B3R - no problems. In B3R, when I created a build type, the following files would get created under source control in the TeamBuildTypes folder: TFSBuild.proj, TFSBuild.rsp, VCOverrides.vsprops, and WorkspaceMapping.xml. However when I try to create a new build type (after migrating to RC), I only get the following files: TFSBuild.proj, TFSBuild.rsp, and WorkspaceMapping.xml. VCOverrides.vsprops is missing. Is this a bug in RC or in a new change that I don't know about Another thing, I can no longer run my build types (created in B3R) because I use the VCOverrides.vsprops for those builds. When those build ...Show All

• SQL Server Introduce Domain functionality to UDDT

  As so rightly stated in http://www.microsoft.com/technet/prodtechnol/sql/70/books/inside6.mspx "Currently, UDDTs don't support the notion of subtyping or inheritance, nor do they allow a DEFAULT value or CHECK constraint to be declared as part of the UDDT itself. These powerful object-oriented concepts will likely make their way into future versions of SQL Server. These limitations not withstanding, UDDT functionality is a dynamic and often underused feature of SQL Server." There's no point bothering with using a UDDT in T-SQL if you can't apply constraints to the UDDT! 1 vote for the introduction of the mentioned features int ...Show All
