• Suitable companion monitors for HP LP3065 30" primary monitor

  - by Bittercoder

  I have an HP LP3065 30" monitor - now I want to add a couple of companion screens to either side of it - I've heard to people suggesting 21" monitors in portrait mode - but it seems difficult to find a suitable panel these day, as 22" wide-screen monitors have become common, and I can't seem to find anything with a suitable 1600 pixel width. Can anyone recommend a suitable monitor, and suggest what criteria are best for picking a suitable monitor - what's important to consider - I'm thinking things like: Exact resolution match? Viewing angle? Small/thin bezel?

• How to clear the entire second level cache in NHibernate

  - by Bittercoder

  I wish to clear the entire second level cache in NHibernate via code. Is there a way to do this which is independent of the cache provider being used? (we have customers using both memcache and syscache within the same application). We wish to clear the entire cache because changes external the database would have occurred (which we have no guarantees re: which tables/entities were affected).

• How do you stop a user-instance of Sql Server? (Sql Express user instance database files locked, eve

  - by Bittercoder

  When using SQL Server Express 2005's User Instance feature with a connection string like this: <add name="Default" connectionString="Data Source=.\SQLExpress; AttachDbFilename=C:\My App\Data\MyApp.mdf; Initial Catalog=MyApp; User Instance=True; MultipleActiveResultSets=true; Trusted_Connection=Yes;" /> We find that we can't copy the database files MyApp.mdf and MyApp_Log.ldf (because they're locked) even after stopping the SqlExpress service, and have to resort to setting the SqlExpress service from automatic to manual startup mode, and then restarting the machine, before we can then copy the files. It was my understanding that stopping the SqlExpress service should stop all the user instances as well, which should release the locks on those files. But this does not seem to be the case - could anyone shed some light on how to stop a user instance, such that it's database files are no longer locked? Update OK, I stopped being lazy and fired up Process Explorer. Lock was held by sqlserver.exe - but there are two instances of sql server: sqlserver.exe PID: 4680 User Name: DefaultAppPool sqlserver.exe PID: 4644 User Name: NETWORK SERVICE The file is open by the sqlserver.exe instance with the PID: 4680 Stopping the "SQL Server (SQLEXPRESS)" service, killed off the process with PID: 4644, but left PID: 4680 alone. Seeing as the owner of the remaining process was DefaultAppPool, next thing I tried was stopping IIS (this database is being used from an ASP.Net application). Unfortunately this didn't kill the process off either. Manually killing off the remaining sql server process does remove the open file handle on the database files, allowing them to be copied/moved. Unfortunately I wish to copy/restore those files in some pre/post install tasks of a WiX installer - as such I was hoping there might be a way to achieve this by stopping a windows service, rather then having to shell out to kill all instances of sqlserver.exe as that poses some problems: Killing all the sqlserver.exe instances may have undesirable consequencies for users with other Sql Server instances on their machines. I can't restart those instances easily. Introduces additional complexities into the installer. Does anyone have any further thoughts on how to shutdown instances of sql server associated with a specific user instance?

• Count number of queries executed by NHibernate in a unit test

  - by Bittercoder

  In some unit/integration tests of the code we wish to check that correct usage of the second level cache is being employed by our code. Based on the code presented by Ayende here: http://ayende.com/Blog/archive/2006/09/07/MeasuringNHibernatesQueriesPerPage.aspx I wrote a simple class for doing just that: public class QueryCounter : IDisposable { CountToContextItemsAppender _appender; public int QueryCount { get { return _appender.Count; } } public void Dispose() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; logger.RemoveAppender(_appender); } public static QueryCounter Start() { var logger = (Logger) LogManager.GetLogger("NHibernate.SQL").Logger; lock (logger) { foreach (IAppender existingAppender in logger.Appenders) { if (existingAppender is CountToContextItemsAppender) { var countAppender = (CountToContextItemsAppender) existingAppender; countAppender.Reset(); return new QueryCounter {_appender = (CountToContextItemsAppender) existingAppender}; } } var newAppender = new CountToContextItemsAppender(); logger.AddAppender(newAppender); logger.Level = Level.Debug; logger.Additivity = false; return new QueryCounter {_appender = newAppender}; } } public class CountToContextItemsAppender : IAppender { int _count; public int Count { get { return _count; } } public void Close() { } public void DoAppend(LoggingEvent loggingEvent) { if (string.Empty.Equals(loggingEvent.MessageObject)) return; _count++; } public string Name { get; set; } public void Reset() { _count = 0; } } } With intended usage: using (var counter = QueryCounter.Start()) { // ... do something Assert.Equal(1, counter.QueryCount); // check the query count matches our expectations } But it always returns 0 for Query count. No sql statements are being logged. However if I make use of Nhibernate Profiler and invoke this in my test case: NHibernateProfiler.Intialize() Where NHProf uses a similar approach to capture logging output from NHibernate for analysis via log4net etc. then my QueryCounter starts working. It looks like I'm missing something in my code to get log4net configured correctly for logging nhibernate sql ... does anyone have any pointers on what else I need to do to get sql logging output from Nhibernate?
