• Why doesn't nHibernate support LIMIT when doing "join fetch"?

  - by HeavyWave

  In nHibernate, if you do an HQL query with "join fetch" to eagerly load a child collection, nHibernate will ignore SetMaxResults and SetFirstResult and try to retrieve every single item from the database. Why? This behavior is specific to HQL, as ICriteria supports eager loading (with an outer join, though) and LIMIT. There are more details here http://www.lesnikowski.com/blog/index.php/nhibernate-ignores-setmaxresults-in-sql/ .

• How can I determine which taskbar application/windows are requesting user attention

  - by Frederic

  I'd like to know how to get a list of the windows requiring user attention from the Windows taskbar. Windows requiring attention appear with a flashing orange color within the Windows taskbar. Un-focused MSN Messenger conversation windows are a good example of this behavior: they turn orange as soon as a remote user sends an instance message. My code targets the Windows 7 platform, but working on older Windows OS would be nice too.

• Python double underscore mangling

  - by gnr

  I am a bit confused by this behavior (using python 3.2): class Bar: pass class Foo: def __init__(self): self.__cache = None bar = Bar() bar.__cache = None foo = Foo() print(vars(bar)) #returns {'__cache': None} print(vars(foo)) #returns {'_Foo__cache': None} I've read up a bit on how double-underscores cause attribute names to be "mangled", but I would have expected the same name-mangling in both cases above. The meaning of a single- and a double-underscore before an object name in Python Any ideas what's going on here?

  - by inutan

  Hello there, I have two Services called TemplateService, TemplateReportService (both defined in one WCF Service Library) to be exposed to the client application. And, I am trying to host these services under Windows Service. Can anyone please guide me if App.config in Windows Service will be same as the one in WCF Library? Here is my app.config in WCF Library: <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.web> <compilation debug="true" /> </system.web> <system.serviceModel> <services> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" ></endpoint> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateService/" /> </baseAddresses> </host> </service> <service behaviorConfiguration="ReportingComponentLibrary.TemplateServiceBehavior" name="ReportingComponentLibrary.TemplateReportService"> <endpoint address="" binding="wsHttpBinding" contract="ReportingComponentLibrary.ITemplateReportService" > <identity> <dns value="localhost" /> </identity> </endpoint> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="http://localhost:8080/ReportingComponentLibrary/TemplateReportService/" /> </baseAddresses> </host> </service> </services> <behaviors> <serviceBehaviors> <behavior name="ReportingComponentLibrary.TemplateServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> </behavior> </serviceBehaviors> </behaviors> </system.serviceModel> </configuration> So, the App.config in my Windows Service(Where I am hosting above two services) will be same as above or there are only some particular sections that I need to move.

• Is there a way I can still use app_offline.htm on my ASP.NET MVC 2 projects? If not, is there an al

  - by CitizenBane

  I loved the features of using app_offline.htm on my ASP.NET WebForm based sites. Upload the file and your app is immediately "offline". Snappy. Now that I'm using MVC 2, I noticed that this no longer works. Is there a way to get this behavior in ASP.NET MVC 2 like it did in WebForms? If not, what alternative do you prefer?

• GCC, -O2, and bitfields - is this a bug or a feature?

  - by Rooke

  Today I discovered alarming behavior when experimenting with bit fields. For the sake of discussion and simplicity, here's an example program: #include <stdio.h> struct Node { int a:16 __attribute__ ((packed)); int b:16 __attribute__ ((packed)); unsigned int c:27 __attribute__ ((packed)); unsigned int d:3 __attribute__ ((packed)); unsigned int e:2 __attribute__ ((packed)); }; int main (int argc, char *argv[]) { Node n; n.a = 12345; n.b = -23456; n.c = 0x7ffffff; n.d = 0x7; n.e = 0x3; printf("3-bit field cast to int: %d\n",(int)n.d); n.d++; printf("3-bit field cast to int: %d\n",(int)n.d); } The program is purposely causing the 3-bit bit-field to overflow. Here's the (correct) output when compiled using "g++ -O0": 3-bit field cast to int: 7 3-bit field cast to int: 0 Here's the output when compiled using "g++ -O2" (and -O3): 3-bit field cast to int: 7 3-bit field cast to int: 8 Checking the assembly of the latter example, I found this: movl $7, %esi movl $.LC1, %edi xorl %eax, %eax call printf movl $8, %esi movl $.LC1, %edi xorl %eax, %eax call printf xorl %eax, %eax addq $8, %rsp The optimizations have just inserted "8", assuming 7+1=8 when in fact the number overflows and is zero. Fortunately the code I care about doesn't overflow as far as I know, but this situation scares me - is this a known bug, a feature, or is this expected behavior? When can I expect gcc to be right about this? Edit (re: signed/unsigned) : It's being treated as unsigned because it's declared as unsigned. Declaring it as int you get the output (with O0): 3-bit field cast to int: -1 3-bit field cast to int: 0 An even funnier thing happens with -O2 in this case: 3-bit field cast to int: 7 3-bit field cast to int: 8 I admit that attribute is a fishy thing to use; in this case it's a difference in optimization settings I'm concerned about.

• Implementing a recently used or favorites dropdown in JComboBox

  - by Kevin Day

  I am looking for code that will add favorites / MRU type behavior to a JComboBox. I could code this myself, but it sure seems like someone else has probably already done it. I found the following (which looks exactly like what I want, but the source code is nowhere near complete): http://java.sys-con.com/node/36658 Any suggestions? I need to keep this relatively light, so I'd prefer to not use a component that's part of a monolithic widget library, and open source is preferred.

• iPhone MKMapView force callout bubble

  - by Mark

  Is it possible to force the call out bubble to be open all the time? I tried putting the following code in didAddAnnotionViews: for (id<MKAnnotation> currentAnnotation in mapView.annotations) { [mapView selectAnnotation:currentAnnotation animated:NO]; } Which works, however, when I single tap the MKMapView the bubble disappear. I want to avoid this behavior.

Thanks in advance.

• Java Encryption issue

  - by r1k0

  I am using PBE encryption to encrypt and decrypt some text on an Android application but I get the BadPaddingException: with the "pad block corrupted" message when I use the wrong private key to decrypt the text. My question, since I am not well versed with encryption in Java, is if this is the normal behavior of the encryption API, because I need to do some logic in the case when the wrong key is entered, but I do not know the private key, nor do I store it anywhere (storing just the encrypted and decrypted check text). Thanks, Mihai

  Hi Everyone: I am wondering if there is some way to subclass UIPasteboard in order to get the selection behavior, but not get the "Cut, Copy, and Paste" options. In addition to this, is there some notification I can subscribe to that returns the NSRange of the selected body of text once it is selected? Thanks for any help!

  I have the following xaml with all the binding removed; <StackPanel Grid.Row="2" Grid.Column="1" Orientation="Horizontal" HorizontalAlignment="Left" Height="20"> <ComboBox x:Name="ddlDay" Width="30"/> If I set the width of the combobox to 200 it works but if I set it to 50 it doesn't size past the default. I'm kinda new to xaml so is this default behavior or what do I do to make the combobox small?

• Android: new Intent() starts new instance with android:launchMode="singleTop"

  - by Stefan Klumpp

  I have Activity A with android:launchMode="singleTop" in the manifest. If I go to Activity B, C and D there I have menu shortcuts to return to my applications root activity (A). The code looks like this: Intent myIntent = new Intent(getBaseContext(), MainActivity.class); startActivity(myIntent); However, instead of returning to the already existing instance A of my MainActivity.class it creates a new instance - it goes to onCreate() instead of onNewIntent(). This is not the expected behavior, right?

  I have a DataGrid in my silverlight application and I'm wondering how to get the same behavior for the vertical scrolling as the horizontal scrolling. When I resize the browser horizontally, The app will bunch up all the controls and the horizontal scrollbar will appear, however when I resize it vertially, the controls at the bottom of the app just move out of view. Does anyone know any tricks to handle something like this?

• Why does this Grails/HQL query with a JOIN return Lists of pairs of domain classes?

  - by ?????

  I'm having trouble figuring out how to do a "join" in Groovy/Grails and the return values I get person = User.get(user.id) def latestPhotosForUser = PhotoOwner.findAll("FROM PhotoOwner AS a, PhotoStorage AS b WHERE (a.owner=:person AND a.photo = b)", [person:person], [max:3]) latestPhotosForUser isn't a list of PhotoOwners. It's a list of [PhotoOwner, PhotoStorage] pairs. Since I'm doing a PhotoOwner.findAll, I would have expected to see only PhotoOwners. Am I doing something wrong, or is this the proper behavior?

• Custom Collection Initializers

  - by Jake

  Classes that implement IEnumerable and provide a public void Add(/* args */) function can be initialized like in the following example: List<int> numbers = new List<int>{ 1, 2, 3 }; which calls the Add(int) function 3x after initializing the List<int>. Is there a way to define this behavior explicitly for my own classes? For example, could I have the initializer call a function other than the appropriate Add() overload?

• registerForRemoteNotificationTypes causes app to exit immediately

  I'm seeing behaviour on my iPhone where debug builds immediately exit after a call to [[UIApplication sharedApplication] registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeAlert]; The debugger reports it exited with the message Terminating in response to SpringBoard's termination. This behaviour doesn't happen on my ad hoc distribution builds. Can anyone explain this behavior?

• Rails OpenID Authentication Plugin No Longer Installs Rake Tasks?

  - by Rich Apodaca

  I'm following the Railscasts tutorial on using OpenID with AuthLogic. This command: $ script/plugin install git://github.com/rails/open_id_authentication.git installs the plugin, but I don't see any OpenID Rake tasks (rake -T). In particular, I can no longer run the task: $ rake open_id_authentication:db:create With previous applications, the Rake tasks were installed without a problem, so what's changed with the plugin? Which version of the plugin do I need to get the behavior I'm looking for? Using Rails 2.3.5.
