  • How can I make a view get bigger again, as soon as the status bar goes back to normal height after a

    - by Thanks
    In the simulator I went to Hardware menu and activated the simulation of bigger status bar during phone call. Now, I tried to make a view in my nib that takes up the whole screen. As soon as the status bar gets smaller, I want my view to get bigger, so it uses that space up there. But regardless of any autoresizing settings, my view will keep pressed down after that status bar gets smaller. There is a empty slot left where the status bar was after hanging up the call. What's that actually supposed to be? Is my app recognizing the status bar as a view, or is the status bar indeed making my screen smaller? I mean...does it mess around with my views as if it was a view itself, or do my views not know about a status bar, but about a smaller screen size when the status bar gets bigger? How do you get your views big again when the status bar returns to normal height?

  • fastest in objC: IsEqualToString:@"" or length > 0?

    - by Cœur
    I'd like to know which one is fastest for testing a non-empty NSString for iOS 4.0+ (iPhone 3G). Note: the strings to test will be 99% of the time from 2 to 100 chars length. if ([foo length] > 0) or if ([foo isEqualToString:@""] == NO && foo != nil) I think it depends if isEqualToString: compares the length first (and in that case first way is faster) or if isEqualToString: compares first character of strings first (and in that case second way might be faster). ps: I already know isEqualToString: is faster than isEqual: which is itself faster than compare:.

  • What happens when I MPI_Send to a process that has finished?

    - by nieldw
    What happens when I MPI_Send to a process that has finished? I am learning MPI, and writing a small sugar distribution-simulation in C. When the factories stop producing, those processes end. When warehouses run empty, they end. Can I somehow tell if the shop's order to a warehouse did not succeed(because the warehouse process has ended) by looking at the return value of MPI_Send? The documentation doesn't mention a specific error code for this situation, but that no error is returned for success. Can I do: if (MPI_Send(...)) { ... /* destination has ended */ ... } And disregard the error code? Thanks

  • How do I check that an entity is unreferenced in JPA?

    - by Martin
    I have the following model @Entity class Element { @Id int id; @Version int version; @ManyToOne Type type; } @Entity class Type { @Id int id; @Version int version; @OneToMany(mappedBy="type") Collection<Element> elements; @Basic(optional=false) boolean disabled; } and would like to allow Type.disabled = true only if Type.elements is empty. Is there a way to do it atomically? I would like to prevent an insertion of an Element in a transaction while the corresponding Type is being disabled by an other transaction.

  • How to null a translation in in gettext system?

    - by Evgeny
    Suppose a simple phrase "In" in English needs to be interpreted as "" - empty string in Russian. Is is possible to specify that in the .po file? What normally happens if you set msgstr "" - you'll get the untranslated key, but I want to get nothing in that specific case. Here is a use case: I have underneath a search bar a set of buttons to select questions (for a Q&A site) from particular scopes - like so: (in English) In: [all] [unanswered] [my own] (in Russian I want) [???] [??? ???????] [???] It just sounds more natural. Yes I can leave out In for english, but I don't want to and I do not want to put button (things in [] are buttongs) html into the 'po' file. Thanks!

  • Text in gtk.ComboBox without active item

    - by Yotam
    The following PyGTk code, gives a combo-box without an active item. This serves a case where we do not want to have a default, and force the user to select. Still, is there a way to have the empty combo-bar show something like: "Select an item..." without adding a dummy item? import gtk import sys say = sys.stdout.write def cb_changed(w): say("Active index=%d\n" % w.get_active()) topwin = gtk.Window() topwin.set_title("No Default") topwin.set_size_request(0x100, 0x20) topwin.connect('delete-event', gtk.main_quit) vbox = gtk.VBox() ls = gtk.ListStore(str, str) combo = gtk.ComboBox(ls) cell = gtk.CellRendererText() combo.pack_start(cell) combo.add_attribute(cell, 'text', 0) combo.connect('changed', cb_changed) ls.clear() map(lambda i: ls.append(["Item-%d" % i, "Id%d" % i]), range(3)) vbox.pack_start(combo, padding=2) topwin.add(vbox) topwin.show_all() gtk.main() say("%s Exiting\n" % sys.argv[0]) sys.exit(0)

  • Does a native php (5+) function exist that does the following in 1 line?

    - by Vinh
    function array_value_from_key($array,$key) { return !empty($array[$key]) ? $array[$key] : null; } The reason I ask is because I have a class function that returns an array. Instead of having to do $myArray = myClass::giveMeArray(); $myValue = $myArray[$myKey]; I'd like to do something along the lines of $myValue = array_value_from_key(myClass::giveMeArray(),$myKey); When an object is returned, you can chain the object such as $myValue = myClass::giveMeObject()->aValue; Voila, nice and clean.. not being able to find what seems to be a simple and trivial function is driving me crazy... PS.. one more example of how I'd like to use such a function if(arrayKeyVal(aClass::giveMeArray(),$myKey)) { do_something(); }

  • Python lxml - returns null list

    - by Chris Finlayson
    I cannot figure out what is wrong with the XPATH when trying to extract a value from a webpage table. The method seems correct as I can extract the page title and other attributes, but I cannot extract the third value, it always returns an empty list? from lxml import html import requests test_url = 'SC312226' page = ('https://www.opencompany.co.uk/company/'+test_url) print 'Now searching URL: '+page data = requests.get(page) tree = html.fromstring(data.text) print tree.xpath('//title/text()') # Get page title print tree.xpath('//a/@href') # Get href attribute of all links print tree.xpath('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') Unless i'm missing something, it would appear the XPATH is correct: Chrome screenshot I checked Chrome console, appears ok! So i'm at a loss $x ('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') [ "£432,272" ]

  • Binding to an XElement

    - by twreid
    I need help binding to an XElement. Basically I am making a editor for certain elements in a web.config and I extract them as XElements and my View binds to a Collection of DataItems which has a property that contains my XElement. When I do Text="{Binding Path=Data, Mode=OneWay, NotifyOnSourceUpdated=True}"/> I get all the text of the Element, but If I try Text="{Binding Path=Data.Elements[], Mode=OneWay, NotifyOnSourceUpdated=True}"/> It doesn't work the TextBox is empty. I am trying to find a way to Template different sections dynamically to make them easier to edit instead of editing raw XMl.

  • WAMP & WordPress - Having issues after installing plugins

    - by user1786083
    I am using WAMP (Apache 2.2.17, PHP 5.4.3) & WordPress 3.4.2. Everything was fine until I started to add and activate plugins now I get different sort of errors on the front-end/Admin e.g. "Notice: Undefined index: plugin_version in C:\repo\wpdev\wp-content\plugins\wp-rss-multi-importer\inc\upgrade.php on line 11" And "Warning: Illegal string offset 'feedslug' in C:\repo\wpdev\wp-content\plugins\wp-rss-multi-importer\inc\rss_feed.php on line 21." IF I deactivate the plugins everything seems to be fine. I have installed WAMP & WP 2X. The plugins work fine on MediaTemple. The error messages vary depending on the plugins. Search Google and came up empty. Thanks in advance.

  • How can you check if a file exists before including/importing it in JSP?

    - by codeninja
    Assuming that requestScope.importMe is expecting a path to a jsp file <c:choose> <c:when test="${!empty requestScope.importMe && fileExists(requestScope.importMe) }"> <c:import url="${requestScope.importMe}" /> ... How can I check if the file exists before trying to include it so that an error is not thrown? I'd like to avoid using inline Java. Something using one of the JSTL tags is the preferred approach.

  • How to implement collection with covariance when delegating to another collection for storage?

    - by memelet
    I'm trying to implement a type of SortedMap with extended semantics. I'm trying to delegate to SortedMap as the storage but can't get around the variance constraints: class IntervalMap[A, +B](implicit val ordering: Ordering[A]) //extends ... { var underlying = SortedMap.empty[A, List[B]] } Here is the error I get. I understand why I get the error (I understand variance). What I don't get is how to implement this type of delegation. And yes, the covariance on B is required. error: covariant type B occurs in contravariant position in type scala.collection.immutable.SortedMap[A,List[B]] of parameter of setter underlying_=

  • Jquery .html replacer just empties my selector, what's wrong!?

    $("#autoNames").html(function (index, html) { var begin = "<script language='javascript' type='text/javascript'> var names = ["; var end = String('];' + '<' + '/' + 'script' + '>'); var result = begin.concat(jsonService, end); $("#autoNames").html(result); return false; }); I can't figure out for the life of me why this doesn't work. I've gotten the html function to work before, but for some reason this just leaves my autoNames tag empty... and i've called an alert() on the result variable and things exist in that string... any clues? Thanks

    this appears to bind, but rows in Details Grid are empty. Something is off/missing? I've also tried {Binding SubCustomers} SubCustomers is a List on parent object. I am able to bind this way to single Fields such as FirstName etc.. just not the subcollection.. <DataGrid.RowDetailsTemplate> <DataTemplate> <DataGrid AutoGenerateColumns="True" ItemsSource="{Binding Source=SubCustomers}" /> </DataTemplate> </DataGrid.RowDetailsTemplate>

  • vcxproj file won't load into solution.

    - by John C
    We've just recently switched to VS 2010 and i had a solution that was working fine. This moring when i try to load the solution i get the error: "An item with the same key has already been added." This occurs when it is trying to load one of our main projects and it is not loaded. I assumed the problem was with my solution so i created a brand new empty solution and tried to load the same vcxproj and got exactly the same error. When i revert the project file to a previous version it works, so apparently it's something in the vcxproj file. However it also appears that i'm the only one in the office that is affected. So some combination of the vcxproj file and my computer seems to be the issue. Has anyone seen anything like this before? Any ideas on a solution? Thanks

  • Rspec > testing database views

    - by Sean McCleary
    How can database views be tested in Rspec? Every scenario is wrapped in a transaction and the data does not look like it is being persisted to the database (MySQL in my case). My view returns with an empty result set because none of the records are being persisted in the transaction. I am validating that the records are not being stored by setting a debug point in my spec and checking my data with a database client while the spec is being debugged. The only way I can think to have my view work would be if I could commit the transaction before the end of the scenario and then clear the database after the scenario is complete. Does anyone know how to accomplish this or is there a better way? Thanks

  • How do you ensure a mimetype in asp.net?

    - by Sem Dendoncker
    Hello, I have the following code to export a zip file: byte[] buffer = FileUtil.FileToByteArray(zipLocation, true); // push the memory data to the client. _ctx.Response.ContentType = "application/zip"; _ctx.Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", String.Format("map{0}.zip", mapId))); _ctx.Response.BinaryWrite(buffer); This code works great. After every export I get a perfectly made zipfile. The problem however is that when I try to import it, the mimetype sometimes is "application/empty". Now I wonder how can I ensure that the mimetype is always added? Cheers, M.

  • PHP - Search array in array

    - by Anonymous2011
    I have tried googling for the past one hour straight now and tried many ways to search for an array, in an array. My objective is, to find a keyword in the URL, and the keywords are in a txt file. This is what i have so far - but doesn't work. $file = "keywords.txt"; $open = fopen($file,'r'); $data = fread($open,filesize($file)); $data = explode(" ",$data); $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $url = parse_url($url); //parse the URL into an array foreach($data as $d) { if(strstr($d,$url)) { echo "yes"; } } This works WITHOUT the text file, or array - but that's not what i want. I'd appreciate it if anyone can assist me.

  • Create multiple columns on one sheet from 1 column on another with logic

    - by user450252
    I am new to VBA and I am struggling trying to make this work. I am in need of a macro that will process each cell\column on Sheet1 and put the results on Sheet2. I'm sure this is pretty easy for those who are more advanced with VB code. It contains many columns.. Anytime we encounter a — or an empty cell, we populate the cell with -999 (see the example on Sheet2) on the first column, which contains "0-2". Then we create 2 new columns and populate them with 0 on the first column and 2 on second column (see example on Sheet2). If a value is found on only one side, we then populate both sides with the same number. As each column is being process in Sheet1 and Sheet1: A B Column1 Column2 Title Title2 0–2 0–4 3 — — 5 — — — 10–23 11—29 And the results should look like this on Sheet2 Sheet2 A B C D Column1 Column1 Column2 Column2 Title-A Title-B Title-A Title-B 0 2 0 4 3 3 -999 -999 -999 -999 5 5 -999 -999 -999 -999 —999 -999 -999 -999 10 23 11 29

  • (newbie) type signature "Maybe a" doesn't like "Just [Event]"

    - by sisif
    i'm still learning Haskell and need help with the type inference please! using packages SDL and Yampa i get the following type signature from FRP.Yampa.reactimate: (Bool -> IO (DTime, Maybe a)) and i want to use it for: myInput :: Bool -> IO (DTime, Maybe [SDL.Event]) myInput isBlocking = do event <- SDL.pollEvent return (1, Just [event]) ... reactimate myInit myInput myOutput mySF but it says Couldn't match expected type `()' against inferred type `[SDL.Event]' Expected type: IO (DTime, Maybe ()) Inferred type: IO (DTime, Maybe [SDL.Event]) In the second argument of `reactimate', namely `input' In the expression: reactimate initialize input output process i thought "Maybe a" allows me to use anything, even a SDL.Event list? why is it expecting "Maybe ()" when the type signature is actually "Maybe a"? why does it want an empty tuple, or a function taking no arguments, or what is () supposed to be?

  • object consisting of jQuery element

    - by Adam Kiss
    hello, current code I've built function to do something over collection of jQuery elements: var collection = $([]); //empty collection I add them with: collection = collection.add(e); and remove with: collection = collection.not(e); It's pretty straightforward solution, works nicely. problem Now, I would like to have an object consisting of various settings set to any jQuery element, i.e.: function addObject(e){ var o = { alpha: .6 //float base: {r: 255, g: 255, b: 255} //color object } e.data('settings', o); } But when I pass jQuery object/element to function (i.e. as e), calling e.data doesn't work, although it would be simplest and really nice solution. question If I have an "collection" of jQuery elements, what is the simplest way of storing some data for each element of set?

  • How to run a progress-bar through an insert query?

If there is an error, I got the error exception and the action will stop - the query stops and the BarcodTbl is empty. How I can see the error and allow the query to continue filling the table?

  • What should I put in the href when I prototype?

    When protyping we often do empty anchors. A very common way to do this is to do something like: <a href="#">Go here</a> But if the client clicks this link, the page will scroll to the top. But if we leave out the href attribute, the link won't behave like a link. I've see stuff like: <a href="javascript;">Go here</a> But it doesn't look right. Any other ideas?
