  • How to inject param in Struts 2 Tag OGNL way

    - by Roy Chan
    Hi Guru, I want to use a property as a param of an object's method. <s:property value="orderProductId" /> returns correct value (e.g. 1) <s:iterator value="%{order.getProductById(1).activations}"> gives me correct value too. But <s:iterator value="%{order.getProductById(#orderProductId).activations}"> doesn't. Not sure why #orderProductId doesn't interpret correctly.

  • Who deleted my sql table rows?

    - by vikasde
    I have an SQL table, from which data is being deleted. Nobody knows how the data is being deleted. I added a trigger and know the time, however no jobs are running that would delete the data. I also added a trigger whenever rows are being deleted from this table. I am then inserting the deleted rows and the SYSTEM_USER to a log table, however that doesnt help much. Is there anything better I can do to know who and how the data gets deleted? Would it be possible to get the server id or something? Thanks for any advice. Sorry: I am using SQL Server 2000.

  • Android - sendOrderedBroadcast help

    - by Donal Rafferty
    I am trying to use a sendOrderedBroadcast in my Android app. I want to be able to send the Intent from one of my applications to another and I then want to get data back from the Application that recieves the Intent, in this case a boolean true or false. Here is the current code: Intent i = new Intent(); i.setAction(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT); i.putExtra("com.testnetworks.QCLEVEL", aProposedTheoreticalQoSLevel); sendOrderedBroadcast(i, null, null, null, Activity.RESULT_OK, null, null); Is this the correct way to achieve what I want? If so what do I use as the resultReceiver* parameter? (3rd parameter) And then how to I recieve data back from the Broadcast? I have done a quick google and not come up with any examples, any help or examples greatly appreciated. UPDATED CODE: sendOrderedBroadcast(i, null, domainBroadcast, null, Activity.RESULT_OK, null, null); class DomainBroadcast extends BroadcastReceiver{ @Override public void onReceive(Context arg0, Intent intent) { String action = intent.getAction(); if(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT.equals(action)){ Log.d("BROADCAST", "Returning broadcast"); Bundle b = intent.getExtras(); Log.d("BROADCAST", "Returning broadcast " + b.getInt("com.testnetworks.INT_TEST")); } } @Override public void onReceive(Context context, Intent intent) { String action = intent.getAction(); if(GlobalData.PROPOSE_IN_DOMAIN_ROAM_INTENT.equals(action)){ Bundle b = intent.getExtras(); int testQCLevel = b.getInt("com.testnetworks.QCLEVEL"); switch(testQCLevel){ case 1: Log.d("QCLevel ", "QCLevel = UNAVAILABLE"); break; case 2: Log.d("QCLevel ", "QCLevel = BELOWUSABILITY"); break; case 3: Log.d("QCLevel ", "QCLevel = VOICE"); break; } intent.putExtra("com.testnetworks.INT_TEST", 100); } So according to the Doc's I should recieve 100 back in my DomainBroadcast reciever but it always comes back as 0. Can anyone see why? *resultReceiver - Your own BroadcastReceiver to treat as the final receiver of the broadcast.

  • Android TabHost: update tabs from tab's activity

    - by joshuadlillie
    I have a TabActivity and am going to have 3 or 4 tabs. In TabA, I would like to have an ExpandableListView, which will list products. I would like TabC to act as a sort of "shopping cart", probably with a ListView of itself. So, my question is: is there a way to interact with the TabHost from the Activity? I would like to be able to click a button inside of TabA and have it update and switch to TabC. Is this possible? Can I get the Tab's activities call it's parents methods?

  • C++ fixed point library?

    - by uj2
    I am looking for a free C++ fixed point library (Mainly for use with embedded devices, not for arbitrary precision math). Basically, the requirements are: No unnecessary runtime overhead: whatever can be done at compile time, should be done at compile time. Ability to transparently switch code between fixed and floating point, with no inherent overhead. Fixed point math functions. There's no much point using fixed point if you need to cast back and forth in order to take a square root. Small footprint. Any suggestions?

  • Does the Internet make us less good programmers? [closed]

    - by stagas
    With all the information and code available nowadays on the Internet has that diminished our capability of remembering or learning stuff just because we know they're available somewhere out there, just a Google away or a StackOverflow question away? For example I find myself visiting php.net quite often to check the syntax of the same functions over and over again, not because my memory sucks, but I don't feel like keeping the information in me, since I know I'll find it again on the net. And about StackOverflow, isn't the process of figuring things out on your own supposed to improve your programming skills? If the answers are all just clicks away, do we actually learn something or just keep a pointer in our heads where to search for it again when we need it? Your thoughts are welcome. Hope it doesn't shut down as subjective or anything, the answers would be really interesting ;)

  • iPad device orientation is null?

    - by Brodie4598
    ([UIDevice currentDevice].orientation); using the above code in my app, all i get is 0 (unknown) is there something thats going wrong here? Seems pretty straightforward edit: more research led me to the problem with using device orientation early in the app, which I am doing. However when I instead use interfaceOrientation, it always returns 1 (portrait)

  • RotateFlipType wrong values when used in settings

    - by Vnuk
    I'm trying to use System.Drawing.RotateFlipType in my settings file. This screenshot summarizes my problem: Each of RotateFlipType values is doubled, and some are missing. If I try to use some of missing values (like Rotate180FlipX, through app.config) - it is simply ignored. Using VS2008 with SP1, vb.net with framework 3.5 on windows 7.

  • NHibernate: Subqueries.Exists not working

    - by cbp
    I am trying to get sql like the following using NHibernate's criteria api: SELECT * FROM Foo WHERE EXISTS (SELECT 1 FROM Bar WHERE Bar.FooId = Foo.Id AND EXISTS (SELECT 1 FROM Baz WHERE Baz.BarId = Bar.Id) So basically, Foos have many Bars and Bars have many Bazes. I want to get all Foos that have Bars with Bazes. To do this, a detached criteria seems best, like this: var subquery = DetachedCriteria.For<Bar>("bar") .SetProjection(Projections.Property("bar.Id")) .Add(Restrictions.Eq("bar.FooId","foo.Id")) // I have also tried replacing "bar.FooId" with "bar.Foo.Id" .Add(Restrictions.IsNotEmpty("bar.Bazes")); return Session.CreateCriteria<Foo>("foo") .Add(Subqueries.Exists(subquery)) .List<Foo>(); However this throws the exception: System.ArgumentException: Could not find a matching criteria info provider to: bar.FooId = foo.Id and bar.Bazes is not empty Is this a bug with NHibernate? Is there a better way to do this?

  • can I make this select follower/following script more organized? (PHP/Mysql)

    - by ggfan
    In this script, it gets the followers of a user and the people the user is following. Is there a better relationship/database structure to get a user's followers and who they are following? All I have right now is 2 columns to determine their relationship. I feel this is "too simple"? (MYSQL) USER | FRIEND avian gary cend gary gary avian mike gary (PHP) $followers = array(); $followings = array(); $view = $_SESSION['user']; //view is the person logged in $query = "SELECT * FROM friends WHERE user='$view'"; $result = $db->query($query); while($row=$result->fetch_array()) { $follower=$row['friend']; $followers[] = $follower; } print_r($followers); echo "<br/>"; $query2 = "SELECT * FROM friends WHERE friend='$view'"; $result2 = $db->query($query2); while($row2=$result2->fetch_array()) { $following=$row2['user']; $followings[] = $following; } print_r($followings); echo "<br/>"; $mutual = array_intersect($followers, $followings); print_r($mutual); **DISPLAY** Your mutual friends avian Your followers avian You are following avian cen mike (I know avian is in all 3 displays, but I want to keep it that way)

  • Pass easing function as variable in AS3

    - by Andrej
    Hi, I've been looking for some time now.. Is is possible to pass easing function as variable in AS3? eg. TweenLite.to(mcDelimiter, resizeTween, { x:(stageWidthHalf-(initStageWidthHalf-mcDelimiteri_X)), ease:Elastic.easeOut } ); TweenLite.to(mcBody, resizeTween, { x:(stageWidthHalf-(initStageWidthHalf-mcBody_X)), ease:Elastic.easeOut } ); ... now if I at some point want to change "Elastic.easeOut" to something else I would have to change it at multiple parts of the code.. Can it be done so I just pass it as a variable and then if I want to change it, do it only on one place? EDIT: ...also, can for eg. if(currentFrame == "FrameLabel") somehow be done? ..meaning, can I pass the currentFrame label name as a variable? Thanks in advance for anwsers, Andrej

  • Python, Ruby, and C#: Use cases?

    - by thaorius
    Hi everyone. For as long as I can remember, I've always had a "favorite" language, which I use for most projects, until, for some particular reason, there is no way/point on using it for project XYZ. At that point, I find myself rusty (and sometimes outdated) on other languages+libraries+toolchains. So I decided, I would just use some languages/libs/tools for some things, and some for other, effectively keeping them fresh (there would obviously be exceptions, I'm not looking for an arbitrary rule set, but some guidelines). I wanted an opinion on what would be your standard use cases (new projects) for Python, Ruby, and C# (Mono). At the moment, I have time like this:Languages: C#: Mid-Large Sized Projects (mainly server-side daemons) High Performance (I hardly ever need C's performance, but Python just doesn't cut it) Relatively Low Footprint (vs the JVM, for example) Ruby: Web Applications Python: General Use Scripts (automation, system config, etc) Small-Mid Sized Projects Prototyping Web Applications About Ruby, I have no idea what to use it for that I can't use Python for (specially considering Python is more easily found installed by default). And I like both languages (though I'm really new to Ruby), which makes things even worse. As for C#, I have not used a Windows powered computer in a few years, I don't make things for Windows computers, and I don't mind waiting for Mono to implement some new features. That being said, I haven't found many people on the internet using it for server-sided *nix programming (not web related). I would appreciate some insight on this too. Thanks for your time.
