  • Is It Possible To Cast A Range

    - by Brad Rhoads
    I'd like to do something like this: def results = Item.findAll("from Item c, Tag b, ItemTag a where c = a.item and b = a.tag and (b.tag like :q or c.uri like :q) " + ob,[q:q]) def items = (Item) results[0..1][0] but I get Cannot cast object '[Ljava.lang.Object;@1e224a5' with class '[Ljava.lang.Object;' to class 'org.maflt.ibidem.Item' I can get what I need with this, but it doesn't seem like it's the best solution: def items = [] as Set def cnt = results.size() for (i=0;i<cnt-1;i++) { items << results[i][0] } items = items as List

  • UIButton does not respond to touch events after changing its position using setFrame

    - by Pranathi
    I have a view controller class (child) which extends from view controller class (parent). In the parent class's loadView() method I create a sub-view (named myButtonView) with two buttons (buttons are horizontally laid out in the subview) and add it to the main view. In the subclass I need to shift these two buttons up by 50pixels. So, I am shifting the buttonView by calling the setFrame method. This makes the buttons shift and render properly but they do not respond to touch events after this. Buttons work properly in the views of Parent class type. In the child class type view also, if I comment out the setFrame() call the buttons work properly. How can I shift the buttons and still make them respond to touch events? Any help is appreciated. Following is snippets of the code. In the parent class: - (void)loadView { // Some code... CGRect buttonFrameRect = CGRectMake(0,yOffset+1,screenRect.size.width,KButtonViewHeight); myButtonView = [[UIView alloc]initWithFrame:buttonFrameRect]; myButtonView.backgroundColor = [UIColor clearColor]; [self.view addSubview:myButtonView]; // some code... CGRect nxtButtonRect = CGRectMake(screenRect.size.width - 110, 5, 100, 40); myNxtButton = [UIButton buttonWithType:UIButtonTypeCustom]; [myNxtButton setTitle:@"Submit" forState:UIControlStateNormal]; myNxtButton.frame = nxtButtonRect; myNxtButton.backgroundColor = [UIColor clearColor]; [myNxtButton addTarget:self action:@selector(nextButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; [myButtonView addSubview:myNxtButton]; CGRect backButtonRect = CGRectMake(10, 5, 100, 40); myBackButton = [UIButton buttonWithType:UIButtonTypeCustom]; [myBackButton setTitle:@"Back" forState:UIControlStateNormal]; myBackButton.frame = backButtonRect; myBackButton.backgroundColor = [UIColor clearColor]; [myBackButton addTarget:self action:@selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside]; [myButtonView addSubview:myBackButton]; // Some code... } In the child class: - (void)loadView { [super loadView]; //Some code .. CGRect buttonViewRect = myButtonView.frame; buttonViewRect.origin.y = yOffset; // This is basically original yOffset + 50 [myButtonView setFrame:buttonViewRect]; yOffset += KButtonViewHeight; // Add some other view below myButtonView .. }

  • How can I find the dimensions of a matrix in Python?

    - by PBD10017
    How can I find the dimensions of a matrix in Python. Len(A) returns only one variable. Edit: Hi Thanks. close = dataobj.get_data(timestamps, symbols, closefield) Is (I assume) generating a matrix of integers (less likely strings). I need to find the size of that matrix, so I can run some tests without having to iterate through all of the elements. As far as the data type goes, I assume it's an array of arrays (or list of lists).

  • Making an efficient algorithm

    - by James P.
    Here's my recent submission for the FB programming contest (qualifying round only requires to upload program output so source code doesn't matter). The objective is to find two squares that add up to a given value. I've left it as it is as an example. It does the job but is too slow for my liking. Here's the points that are obviously eating up time: List of squares is being recalculated for each call of getNumOfDoubleSquares(). This could be precalculated or extended when needed. Both squares are being checked for when it is only necessary to check for one (complements). There might be a more efficient way than a double-nested loop to find pairs. Other suggestions? Besides this particular problem, what do you look for when optimizing an algorithm? public static int getNumOfDoubleSquares( Integer target ){ int num = 0; ArrayList<Integer> squares = new ArrayList<Integer>(); ArrayList<Integer> found = new ArrayList<Integer>(); int squareValue = 0; for( int j=0; squareValue<=target; j++ ){ squares.add(j, squareValue); squareValue = (int)Math.pow(j+1,2); } int squareSum = 0; System.out.println( "Target=" + target ); for( int i = 0; i < squares.size(); i++ ){ int square1 = squares.get(i); for( int j = 0; j < squares.size(); j++ ){ int square2 = squares.get(j); squareSum = square1 + square2; if( squareSum == target && !found.contains( square1 ) && !found.contains( square2 ) ){ found.add(square1); found.add(square2); System.out.println( "Found !" + square1 +"+"+ square2 +"="+ squareSum); num++; } } } return num; }

  • What's the actual windows media player maximum banner width?

    - by William
    When looking at the documentation for the banner tag in windows media metafiles all the documentation says there is a maximum size of 194 x 32 pixels. http://msdn.microsoft.com/en-us/library/dd562478(v=VS.85).aspx However, when experimenting with larger images they seem to be displaying correctly. Is there some real undocumented limitation here? Will it get cut off on different/older versions?

  • Analysing objects generated by a Java application in between GCs.

    - by elec
    Is there a tool which could be used to analyse the objects being created between two separate garbage collection run (= number of objects created and their type) ? Heapdumps dont really work here as they perform a GC when they're invoked (or at least that's what I observed everytime so far), and I want to see which objects are collected by the GC, not which objects are left after the GC run, if that makes sense. ...or is it possible somehow to inspect the nature and size of objects being collected by the garbage collector ?

  • Difference in displaying inner div between IE and Chrome

    - by Gaara
    I have this code that has one "outerDIV" that contains an "innerDIV". On chrome the "innerDIV" size is 491px, whereas on IE it is 425px (same as outerDIV). Hence, on Chrome I can see the first two children of "innerdiv": "My test string #1" and "test2". But for IE I can only see the first child. I am not quite sure what the "right" behavior should be, as firefox does the same as IE. However I would like to have IE do the same as Chrome. I have been experimenting with some css styles (mainly overflow and display), but still can't make it right: IE will expand its height instead of its width to make the elements fit. Can you guys help me figure out a way to change the css so that IE will wraps the div elements inline? As a restriction though, I cannot change the width on the HTML. As a benefit, I am using a css that only loads for IE to patch these kind of IE inconsistencies. The same css will NOT load for chrome, so I don't need to worry about messing with chrome when changing the IE CSS. Thanks in advance! <html> <head> <style type="text/css"> <!-- body { font-family: helvetica; } .myContainer { overflow: hidden; border: 1px solid rgba(0, 0, 0, .5); font-size: 14pt; height: 49px; line-height: 49px; overflow: hidden; display: block; } .myContainer > DIV { float: left; white-space: nowrap; display: block; } .myContainer .item:first-child { padding-left: 10px; } .myContainer .item { float: left; padding-right: 32px; } --> </style> </head> <body> <div id="outerDIV" class="myContainer" style="display: block; width: 425px;"> <div id="innerDIV"> <div class="item"> --------My test string #1-------- </div> <div class="item"> ------test2------- </div> <div class="item"> test </div> </div> </div> </body> </html>

  • Auto scrolling control (WinAPI)?

    - by user146780
    In C# (.Net) you can create a panel and set autoscroll to true. you can then add controls into it, including beyond it's size, then it will scroll. I was wondering if when using the real WinAPI in c++ (not .net) how one could acheive the same result. Must I keep track of the controls inside and move them all when I scroll or is there an easier way like in C#. Thanks

  • Better way to write an object generator for an RAII template class?

    - by Dan
    I would like to write an object generator for a templated RAII class -- basically a function template to construct an object using type deduction of parameters so the types don't have to be specified explicitly. The problem I foresee is that the helper function that takes care of type deduction for me is going to return the object by value, which will result in a premature call to the RAII destructor when the copy is made. Perhaps C++0x move semantics could help but that's not an option for me. Anyone seen this problem before and have a good solution? This is what I have: template<typename T, typename U, typename V> class FooAdder { private: typedef OtherThing<T, U, V> Thing; Thing &thing_; int a_; // many other members public: FooAdder(Thing &thing, int a); ~FooAdder(); void foo(T t, U u); void bar(V v); }; The gist is that OtherThing has a horrible interface, and FooAdder is supposed to make it easier to use. The intended use is roughly like this: FooAdder(myThing, 2) .foo(3, 4) .foo(5, 6) .bar(7) .foo(8, 9); The FooAdder constructor initializes some internal data structures. The foo and bar methods populate those data structures. The ~FooAdder dtor wraps things up and calls a method on thing_, taking care of all the nastiness. That would work fine if FooAdder wasn't a template. But since it is, I would need to put the types in, more like this: FooAdder<Abc, Def, Ghi>(myThing, 2) ... That's annoying, because the types can be inferred based on myThing. So I would prefer to create a templated object generator, similar to std::make_pair, that will do the type deduction for me. Something like this: template<typename T, typename U, typename V> FooAdder<T, U, V> AddFoo(Thing &thing, int a) { return FooAdder<T, U, V>(thing, a); } That seems problematic: because it returns by value, the stack temporary object will be destructed, which will cause the RAII dtor to run prematurely. One thought I had was to give FooAdder a copy ctor with move semantics, kinda like std::auto_ptr. But I would like to do this without dynamic memory allocation, so I thought the copy ctor could set a flag within FooAdder indicating the dtor shouldn't do the wrap-up. Like this: FooAdder(FooAdder &rhs) // Note: rhs is not const : thing_(rhs.thing_) , a_(rhs.a_) , // etc... lots of other members, annoying. , moved(false) { rhs.moved = true; } ~FooAdder() { if (!moved) { // do whatever it would have done } } Seems clunky. Anyone got a better way?

  • Random number from a range in a Bash Script

    - by Jack
    Hi, I need to generate a random port number between 2000-65000 from a shell script. The problem is $RANDOM is only a 16bit number, so im stuck! PORT=$(($RANDOM%63000+2001)) would work nicely if it wasn't for the size limitation. Does anyone have an example of how I can do this, maybe by extracting something from /dev/urandom and getting it within a range? Thanks.

  • Are fragments of hashes collision-resistent?

    - by Mark
    Let me see if someone would mind clearing up this elementary point about md5 and hashing. If you only use the first 4 bytes of an md5 hash, would that mean theoretically only 1 in 255^4 chance of collision. iow is that the intention with it (and other hash algorithms) - that you only have to use a small portion of the returned hash (say the hash is of a file of some size).
