• .NET Development SerializationException on Sending Data Back to Serviced Component Via Remoting

  I've developed a distributed app in C#. The various components of the application are as follows: A SQL Server database. Data Access Layer - Hosted in COM+ as Library application. Business Logic Layer - Hosted in COM+ as Server application. User Interface (Windows-based). Types - Exposes various typed DataSet objects used by DAL, BLL, and UI. ServerHost - A Console app that exposes the BLL objects via remoting. The application is hosted on a machine running Windows XP SP2. The DAL and BLL are both hosted in COM+ on the same server that hosts the SQL Server database. Both of these projects and the UI project reference the Types library that, among other things, has strongly typed DataSet objects that are used by the ...Show All

• SQL Server SQL Server performance problems

  Hi, I am running SQL Server 2005 SP1 on Windows Server 2003 SP1 on an Intel Xeon 3GHz CPU, with 2GB of RAM, and a 100GB hard disk. The database engine, analysis services, and reporting services are all on the same server. I now have a number of databases and cubes on the server, and am starting to run into performance problems. When a spreadsheet tries to query the database engine the same time that an Analysis Services cube is being processed or an SSIS package is updating some database tables, the query will often timeout. I realise that the best solution is probably to place Analysis Services on its own server, although the extra cost means that this is not a possibile solution. Are there any recommendations for improving the p ...Show All

• SQL Server Loading excel file(.xls) into sqlserver (ASP.net web application)(ASP.net framework 1.0)

  I am using framework 1.0 to do the above tasks. Since there is no fileupload function in .net 1.0, i will be using the html control tools (file field) to do the upload option. i have totally no idea of how to start coding it...can anyone guide me through the steps thanks Although your solution has 3 layers, I don't think it truly fits the definition of a 3-tier design (take a look at the defn at http://en.wikipedia.org/wiki/Three-tier_%28computing%29 ) because your layers are tightly coupled to implementation details of the other layers (e.g. your web app processing has detailed knowledge of how the presentation layer stores information in the Excel spreadsheet).

• Software Development for Windows Vista What happened to the HelpDeskSupport sample app in .NET RC1 and WinWF CTP5?

  Dear all, The HelpDeskSupport sample was in the SDK up until Beta 2.2, but it seems to have vanished. It looks like it exists on the web, but the links to the source code from the documentation are broken. I used it to obtain classes for "simple" communication between asp.net and a state machine workflow. This seemed to work ok, so I didn't look into it to any degree, but under RC1, using manual scheduling, it crashes because the communication interface uses a class global static to keep track of the DataPipeList and this does not persist across re-starts. The idea of a class that abstracts to data pipes with defined message formats is a good one, although the implementation of it here is a bit clumsy. Is there a samp ...Show All

• SQL Server ifilters and sql express

  Hi there, does anyone know if sql server 2005 express support ifilters I've installed the adobe pdf ifilter but i still can't perform full text search in pdf document. Cheers, Sylvain Hi Sylvain, SQL Express should support iFilters. It's been suggested that your issue may be related to some new security lock down we've done in SQL 2005. You would need to change a couple settings for FTS to get this to work, but changing these settings opens your machine to a bit more risk. Exec Sp_fulltext_service 'verify_signature', 0 Exec Sp_fulltext_service 'load_os_resources', 1 Then re-crawl your index It's also been mentioned that iFilters are 32-bit only. If this doesn't resolve your i ...Show All
