I wrote some quick and dirty ADO.NET code to go against an RSS feed instead of a flat XML file today.  In the process I had to figure a way to limit the number of rows returned by the function, which returns a DataTable.  The simplest method I found was this one, which uses the DataTable.Select() method.  Using this technique, you ...

I have a very large table in a SQL database that I need to clean up some old data on.  I've already copied all of the data to another table in another database with a different schema.  I have a legacy application that still uses the old data, but the data goes back for years, and now that it's in the new system, I'm willing to remove at ...

For an admin application I've been working on, we're using a third party reporting tool to serve up reports to our users over the Internet.  The reports have a nice designer that works with XSD files in Visual Studio.  Not particularly fond of XSDs as a means of data access, I thought I would limit the damage by having only one of them ...

I had a situation where I was using a DataSourceControl (actually an LLBLGenProDataSource2,which inherits from DataSourceControl) bound to a grid, and I wanted the grid to refresh its contents whenever I added or deleted an item from it.  I discovered a neat trick noted here, which is that if you touch the SelectParameters collection of the ...

Frans announced yesterday that LLBLGen 2.0 has been released!  I’ve been using LLBLGen happily for several years now.  It is a very solid ORM tool and I’m looking forward to using the new version going forward.  You can read a list of new features and enhancements here.  If you haven’t used LLBLGen before, I ...

Something I need to do from time to time is get just the date part of a datetime value in SQL.  I found a cool way to do it on SQLJunkies today. select convert(varchar,DateColumn,101) The 101 means “mm/dd/yyyy” format, but there are a bunch of other codes you can use.  108 will return just the time “hh:mm:ss” for instance. Update: 101 ...

A new site I'm using to push me updates of interesting blogs is DotNetSlackers.com.  Sign up for their mail service, and you'll get a single daily email with that day's posts arranged by keyword category.  I've been pretty lax in firing up my RSS aggregator client, so this is a good way for me to at least make sure I'm not missing ...

Julie and I were having issues with getting Sql Query Notifications to work for ASP.NET cache dependencies (for our DevConnections talks).  The trick was this: sp_dbcmptlevel yourdatabasename,90 Julie did most of the research on this one, with help from Sushil Chordia and Leonid Tsybert from Microsoft.  She has more on her blog, but ...

I found this post by Rushi Desai on Invalidating cached result sets using SQL Server Query Notification.  It's from March so it's a bit out of date, but it has some working ASP.NET sample code (well, working in Beta 2, I presume, but pretty close for RTM).

I'm working on my caching presentation for Fall ASP.NET Connections and a few user group presentations.  Those few who read my blog can enjoy some early looks at my research, which I'll detail here for my own future reference (and yours!). First of all I only recently found a great article on Query Notifications in ADO.NET 2.0 ...
