• Visual Studio 2008 (Pre-release) Enumerations?

  Just getting my hands on this: Is there a built-in way to specify a property type to be of an enumeration type   What I'm having to do now is use the generated byte-property as a private value field, and then creating a public property in the partial class that casts it to my enumeration. Otherwise, this is freaking cool!  Really digging this, team... you have no idea. :) Keep it up! Mike We are looking into Enumeration types currently. Our plans are not finalized yet but, yes, we also feel that it would be nice to have them. ...Show All

• Visual Studio Express Editions Package Load Failure

  I tryed several times to install and uninstall VB2005 Express but I always get the error: "Package Load Failure Package "Visual Studio XML Editor Package" has failed to load properly {GUID=a guid}. Note that during a "Repair" I got an error in Framework 2.0 installation. But then it went on. The above failure does not allow to open a project nor to create a new project Thanks for help Many thanks, however I solved the problem. It was caused by a not correct installation of Framework 2.0. Unfortunately when I tried to reinstall or repair it, I got a system error. Then I downloaded the very useful tool dotnetfix_cleanup from: http://astebner.sts.winisp.net/Tools/dotnetfx_cleanup_tool.zip I launched it, I reinst ...Show All

• SQL Server A deadlock when selecting from a view with replicated tables.

  I moved this from another forum because it seems more related to replication the longer I look into it! The following code often dies on a deadlock. I have also seen "Spid x blocked by Spid x", where x is the spid of this connection. The view selects from several tables and some other views as well, and many of the underlying tables are being updated by replication. I have seen cases where the replication Insert proc participated in the deadlock, and the table being inserted into is joined twice in the view, suggesting that somehow this causes the deadlock or makes a deadlock more likely SELECT * INTO dbo.tbl_stg_LoansMarketingFirstBorrower FROM view_loans_marketing_first_borrower OPTION (MAXDOP 1) I do not under ...Show All
