• NHibernate Many-to-many with a boolean flag on the association table

  - by Nigel

  Hi I am doing some work on an application that uses an existing schema that cannot be altered. Whilst writing my NHibernate mappings I encountered a strange many-to-many relationship. The relationship is defined in the standard way as in this question with the addition of a boolean flag on the association table that signifies if the relationship is legal. This seems somewhat redundant but as I say, cannot be changed. Is it possible to define this relationship in Nhibernate without resorting to using a third class to represent the association? Perhaps by applying a filter? Many thanks.

• How to break whenever any line of code executes

  - by Aequitarum Custos

  I have a very strange bug, which I believe is caused by some code we have executing, but I'm not sure where. We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing. Is there a way to set visual studio to break whenever anything executes? For those curious about the problem, every now and then, we have a few Rich Text Boxes that refuse to lose focus. You can't click out of it or tab out of it. We have no On Validation or On Text Changed events attached to the control, and believe it's an event attached somewhere else to something we just aren't noticing.

• Cannot debug tests using Resharper

  - by Mike

  Hi, I'm not able to debug my tests using Resharper-Debug option in my project. I have seen this issue raised by lots of people, but has't come across a solid suggestion which solves my issue. The strange thing is that, if I create a sample project and write a simple unit test, I'm able to debug it without any issues.However when I try to do this in my current project, it simply throws a dialog box saying "Cannot Launch Debugger".I have checked this with my peers, and they does't face this issue :( Also I don't have any issues while running the test. It's an XP machine and following is the version of resharper: JetBrains ReSharper 5.1 C# Edition Build 5.1.1753.4 on 2010-10-15T15:51:30 Licensed to: XXXXXXX Plugins: none. Visual Studio 9.0.21022.8.

• bash find xargs grep only single occurence

  - by keftebub

  hi. maybe it's a bit strange - and maybe there are other tools to do this but, well.. i am using the following classic bash command to find all files which contain some string: find . -type f | xargs grep "something" i have a great number of files, on multiple depths. first occurence of "something" is enough for me, but find continues searching, and takes a long time to complete the rest of the files. what i would like to do is something like a "feedback" from grep back to find so that find could stop searching for more files. is such a thing possible? thank you

• Can't find Peopleware anywhere?

  - by ooo

  Many folks say that Peopleware is one of the best books for software professionals and managers, as I see a lot of people recommending it in the "have to read list." The strange thing is that I can't find a bookstore anywhere that actually has it. I found it on Amazon, but Borders, Barnes & Nobles, etc. don't have it and keep telling me it's out of print. Can anyone shed some light on whats going on here? Amazon doesn't stock it, it says its available from a few 3rd party sellers, but I tried two of them and both of them eventually refunded me and cancelled the order after stalling for a month.

• Using jQuery in WordPress plugin admin page?

  - by Volmar

  I have a strange problem that probably have a really simple explanation that i've just havn't found. I'm making a WordPress plugin and i want to use jQuery in my settings-page for the plugin. My JS functions look like this: jQuery(document).ready(function() { alert('load test'); //ADMIN FUNCTION $('#mrc_imp_img').click(function(){ alert("test"); }); //FRONT END FUNCTION $("ul.mrc li").hover(function() { $(this).find('p').fadeIn(); } , function() { $(this).find('p').fadeOut(); }); }); The "load test"-alert is being loaded when the document is ready so jquery is properly loaded. The front end function is being used on pages and that's working fine to. the problem is the admin function, it's not working at all. is there a speial way i have to write a .click()-function to get it to work on my settings-page for the wordpress plugin?

• iPhone + OpenGL + Touches: FPS drop

  - by Anton

  Hey there, Recently I ran into a very strange issue: touching the screen of the iPhone and moving a finger around can eat up to 50% of my FPS. Yeah, I checked my code for possible bottlenecks – not the issue. The last resort I tried before writing this post – commenting out all the touch processing code and looking at FPS then. Results are: no touches – 58-60. Touching and moving the finger – 35-40 FPS instantly. The rendering is done in a separate thread, so that no main runloop events shall collide with it. However, it's very crushial for me (and the game I develop) to resolve this issue, because such FPS drop is really noticeable. Thank you for your help in advance. UPDATE: seems that setting rendering thread's priority to higher value helps a bit...

• Why does Java return a date in GMT-4.5 when choosing Co-ordinated Universal Time time zone in Window

  - by Simon Nickerson

  We have seen a strange issue on some Windows XP machines involving the "Co-ordinated Universal Time" time zone. Not all Windows XP machines seem to have it, but on those that do, the following simple Java program public class TimeTest { public static void main(String[] args) { System.out.println(java.util.TimeZone.getDefault()); System.out.println(new java.util.Date()); } } on JDK 1.6.0_06 prints: sun.util.calendar.ZoneInfo[id="America/Caracas",offset=-16200000,dstSavings=0,useDaylight=false,transitions=5,lastRule=null] Fri Nov 13 05:34:14 VET 2009 (i.e. 4 and a half hours behind GMT). I should add that I am based in London, and have never been to South America. :-) My questions are: Where does Java get this time zone from? I thought Co-ordinated Universal Time was supposed to be the new name for GMT. Why do some Windows machines have this time zone but not others?

  - by Willy

  Hi all, I try to create a WebSphere queue manager in production env. Before this I manage to create the queue manager in the development env with no problem. I'm using this script to create the queue manager: crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm But it give no response (no error or success message). When I try to start the queue manager (strmqm test1.qm) it give "AMQ8118: WebSphere MQ queue manager does not exist." Then I notice lots of strange thing that supposed not happen: I can run the "crtmqm -u SYSTEM.DEAD.LETTER.QUEUE test1.qm" several times without any error I can just type crtmqm and got no response I can type crtmqm -y (which is not possible since there is no -y argument) and still no response Can anyone tell me what is wrong?

• Losing scope for DataContex using LINQToSQL intermediately

  - by greektreat

  I am having a weird Situation with my DataConext. All My code is in C# I have a DLL project for my data access layer and business Layer which and Winforms project for my UI layer. My Data access Layer's Namespace is xxx.Data this is where have my xxx.dbml I also have xxx.Data.BusinessObjects name space of course for my business object in that project In my UI Layer I have these namespaces xxxApp(for Forms), xxxApp.Controls (For Controls) I have lost scope of the DataContext, it was accessible now when I do a Rebuild Solution I sometimes get compile errors saying for example: Error 34 'xxx.Data.xxxDataContext' does not contain a definition for 'SubmitChanges' and no extension method 'SubmitChanges' accepting a first argument of type 'xxx.Data.xxxDataContext' could be found (are you missing a using directive or an assembly reference?) Also intelisense doesn't recognize the methods and table classes from my xxxDataContext anymore I can access all object fine when I am in the DLL project but now in the Winforms project this is very strange. If anyone can help me out I would be extremely grateful!

• getElementsByTagName() equivalent for textNodes

  - by levik

  Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it's a little strange that I can get all the <input>s with a single built-in call, but not all textNodes.

• jQuery get request against Sinatra does not get text

  - by jerhinesmith

  I have a very simple sinatra site that I'm trying to access via ajax through jQuery. To keep things incredibly simple, this code snippet: get '/behavior_count' do "60" end which returns "60" in the browser, shows up as an empty string when attempting to access the site via $.get in jQuery. The strange part is in Firebug, while the Response is empty, the HTTP header correctly describes Content-Length as 2, and I can see the request show up on the server. Is there something specific to Sinatra that isn't returning my data, or am I not using jQuery correctly? If it helps, I also tried this code: get '/behavior_count' do content_type 'text/plain', :charset => 'utf-8' "60" end and my jQuery looks like $.get('http://mysite:4567/behavior_count'); // Ignore the response, but // watch the request in firebug Any ideas?

• UITextField showing trash instead of characters

  - by krasnyk

  There's quite a strange thing happening to text fields in application I'm developing (see image below).  [1]: http://img7.imageshack.us/img7/1449/zrzutekranu20100506godz.png At some point in the application I'm using    - (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [[(TextFieldView*)[self view] usernameTextField] becomeFirstResponder];    } Which results in the above image. If it's called in viewDidAppear - everything is fine. The funny thing about this error is that it breaks ALL text fields throught the application. Has anyone ever encountered such an error? Might it be related to openGL use?

• QTMovieView always remains at top

  - by Pickasaby

  I have made an applications which contains a main canvas view. In which i add some subview (NSView) of different kind. Means say subView1 is a container for PDFView, subView 2 is a container for a WebView and subView 3 is a container for QTMovieView. I can select and drag these views on main canvas view. The strange thing that happens is, when ever i drag a subview 1 or 2 and it intersects subview 3, sunbview 3 never allows any other view to come on top of it, coz it contains a 'QTMovieView' . I tried replacing QTMovieView with QTMovieLayer, and then attach a QTMovie with QTMovieLayer, still the problem prevails. Is there any way so that my QTMovieView/QTMovieLayer acts in a normal manner as does other NSView do.

• Apache HTTPClient returns an empty page

  - by mariosangiorgio

  Hi, I am using the Apache HTTPClient for Java and I'm facing a really strange issue. Sometimes when I try to get a dynamically generated page it returns its actual content, but other times (with another parameter) all I get is a short sequence of \t,\r and \n. How could I track what's going on on the different cases in order to find where is the bug? My usage of the library is pretty straightforward, all I do is this few calls on an initialized HTTPClient object: String content = "/pageIwant.jsp?parameter=10101010"; HttpGet request = new HttpGet(content); HttpResponse response = client.execute(targetHost, request); HttpEntity entity = response.getEntity(); String page = EntityUtils.toString(entity);

• sqrt(int_value + 0.0) ? The point?

  - by Earlz

  Hello, while doing some homework in my very strange C++ book, which I've been told before to throw away, had a very peculiar code segment. I know homework stuff always throws in extra "mystery" to try to confuse you like indenting 2 lines after a single-statement for-loop. But this one I'm confused on because it seems to serve some real-purpose. basically it is like this: int counter=10; ... if(pow(floor(sqrt(counter+0.0)),2) == counter) ... I'm interested in this part especially: sqrt(counter+0.0) Is there some purpose to the +0.0? Is this the poormans way of doing a static cast to a double? Does this avoid some compiler warning on some compiler I do not use? The entire program printed the exact same thing and compiled without warnings on g++ whenever I left out the +0.0 part. Maybe I'm not using a weird enough compiler?

• Methods in the namespace System.Security.Cryptography take 2 minutes to perform when service is hosted in IIS

  - by Asaf Saf

  I built an ASP.NET web-service that uses the System.Security.Cryptography namespace when it handles its requests. When I hosted the service in ASP.NET Development Server, everything worked fine. Then I moved the service into IIS, still using localhost addresses, and surprisingly, each time the service calls a method from the specified namespace, it takes 2 minutes to complete! If a single request requires the service to call 3 methods of the specified namespace, then the request takes total of 6 minutes to complete! The traces show that the request has been received on time, and they show an interval of around 2 minutes upon each call to the specified namespace. Did anyone see this strange behavior elsewhere? Any speculation would be appreciated!

• JSF Rendering Issue (Page getting cached)

  - by Shamik

  I am facing a strange issue with JSF. I have developed one controller and bind it to request scope. I need to access one jsf page like http://localhost:8080/selectRule.jsf?type=A and on the same IE session I want to issue another request like http://localhost:8080/selectRule.jsf?type=B as we can see, only the type is changing here. This is why I have a ruleController bound to request scope, so that every request, creates the controller and pulls out the data depending upon type. I have a private HtmlSelectOneMenu choices item in the page. What I see is, somehow only once in the session the getChoices() is getting called. This is what I see For each url, one new ruleController object is getting created. Only first time getChoices() are called. In the subsequent time, if I change the URL in the web browser, the getChoices() method are not getting called though a new controller is getting created. Note: I am using JSF 1.1

• Arguments to convince to switch from CVS to SVN

  - by ereOn

  Hi, The UNIX department of my company currently uses CVS as source-version control system. They use it in a very strange way: different repositories for development/testing/production code (for the same project), no one tags anything, weird directory architecture, and so on. The system has been set for ages but now, I have an opportunity to organize a meeting where I have to suggest changes. I'd like to make them change from CVS to SVN (Mercurial or Git might be even better, however I can't really recommand using a system I don't know well, and switching to SVN will already be a great step forward). I don't have much experience with CVS so I can't compare them efficiently: I just know it doesn't support atomic operations and that it is deprecated. What killer arguments would you use to convince my collegues to do the switch ? Thank you very much.

• Xcode automatically converts the object to NSArray

  - by Farrukh Javeid

  I have been working on an app and during the development, I am facing a very strange problem. I have a NSMutableArray tempSortedArray, which is full of objects of Store types. All the objects are valid as I can see them in my GUI, the problem arises when I iterate through the array, at index 90, which can be generally anyone, the XCode converts the Store object to NSMutableArray object. Any idea, why this is happening. This is the code to check out what I am doing: NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"cashBack" ascending:NO]; NSArray *sortDescriptors = [NSArray arrayWithObject:sortDescriptor]; NSArray *sortedArray = [storesArray sortedArrayUsingDescriptors:sortDescriptors]; for (int i = 0; i < [tempSortedArray count]; i++) { Store *currentStore = [tempSortedArray objectAtIndex:i]; NSLog(@"store class: %@", [currentStore.class description]); if (currentStore.cashBackTypeString != (id)[NSNull null]) { //do whatever is required to do here }

• Irregular layout ItemsControl

  - by firoso

  I have a strange layout for an ItemsControl. I have a 4x6 grid with the following pattern: 1 2 3 4 13 14 15 16 5 6 7 8 17 18 19 20 9 10 11 12 21 22 23 24 Is there an easy way to do this? should I be using 6 Items Controls and take "sections" of my list? is there a good way to do this? What about notification? It's important to note that I may, or may not, have all 24 entries present, but the layout needs to be maintained (think of it like filled slots on a bingo card or something)
