• SQL Server Stuck between "Failed to generate user instance" and "An attempt to attach...failed"

  I wrote an application using Visual Studio 2005 beta 2 which uses a SQL Express .mdf file, included in the project, for the database.  After installing Visual Studio 2005 RC and the SQL Express that comes with it (I followed all of the uninstall instructions first) I can no longer add a SQL Express database to any of my projects, nor can I open the SQL Express database in my original project.  When I try either of these tasks, I get the "Failed to generate user instance of SQL Server due to a failure in starting the process for the user instance.  The connection will be closed."  I read the thread which dealt with this er ...Show All

Cant find any help on it. Can someone enlighten me please Thanks Mike No, the solution should be and still is -- Microsoft need to fix VS 2005 Deployment projects -- when one creates a deployment project in VS 2005 based on the primary output of your project file, it should KNOW that .NET 2.0 is a prerequisite and add appropriately. In some cases the build on primary output just doesn't work correctly -- this is what Microsoft need to address to solve the p ...Show All

• .NET Development How can i get the maximum path length?

  I didn't find any enum type that gives me this platform constant. How could i get it I mean the maximum character number which i could use to identify a file path. Thx. There is no built-in const or enum that provides this information.  Currently you have to hard code it.  248 characters for the maximum path length and 260 for the maximum filename length.

• SQL Server Use View to speed up?

  In my query, there is two fields using User Defined Function(UDF).  It is the UDF calculation that slow down the query.  The query will eventually become slow when more records(say over 1000) is return. I am thinking to use View to maintain the result of the query so as to speed up the process.  Is it possible   If not, what should I do Thanks. Yes, you can simplify complex query by using UDF but that doesn't mean that you will get the best performance. Query optimizer can do a better job on objects that contain statistics like tables/views. But once you use scalar UDFs in SELECT list o ...Show All
