  • Liftweb Menu customization

    - by DataSurfer
    I want to create a menu that looks like: HOME | FOO | BAR | ABOUT | CONTACT How might I go about doing this? Here is what I have tried: <lift:Menu.builder ul:class="menu" li_item:class="current" /> and ul.menu li { display: inline; list-style-type: none; text-transform: uppercase; border-right: 1px solid white; padding-right: 5px; } li.current span { background: white; color: black; padding: 5px 5px 3px 5px; font-size: 11px; } li.current a, a:visited, a:link { color: white; padding: 5px 5px 3px 5px; font-size: 11px; } This gets close, but it doesn't look quite right. Also you end up with an extra line at the end. I want the lines to be the same height as the text. http://lh5.ggpht.com/_5DxlOp9F12k/S2aFQHfupzI/AAAAAAAAJiY/Ds0IpEyu78I/s800/menu.png

  • Determining if an unordered vector<T> has all unique elements

    - by Hooked
    Profiling my cpu-bound code has suggested I that spend a long time checking to see if a container contains completely unique elements. Assuming that I have some large container of unsorted elements (with < and = defined), I have two ideas on how this might be done: The first using a set: template <class T> bool is_unique(vector<T> X) { set<T> Y(X.begin(), X.end()); return X.size() == Y.size(); } The second looping over the elements: template <class T> bool is_unique2(vector<T> X) { typename vector<T>::iterator i,j; for(i=X.begin();i!=X.end();++i) { for(j=i+1;j!=X.end();++j) { if(*i == *j) return 0; } } return 1; } I've tested them the best I can, and from what I can gather from reading the documentation about STL, the answer is (as usual), it depends. I think that in the first case, if all the elements are unique it is very quick, but if there is a large degeneracy the operation seems to take O(N^2) time. For the nested iterator approach the opposite seems to be true, it is lighting fast if X[0]==X[1] but takes (understandably) O(N^2) time if all the elements are unique. Is there a better way to do this, perhaps a STL algorithm built for this very purpose? If not, are there any suggestions eek out a bit more efficiency?

  • How would you code an efficient Circular Buffer in Java or C#

    - by Cheeso
    I want a simple class that implements a fixed-size circular buffer. It should be efficient, easy on the eyes, generically typed. EDIT: It need not be MT-capable, for now. I can always add a lock later, it won't be high-concurrency in any case. Methods should be: .Add and I guess .List, where I retrieve all the entries. On second thought, Retrieval I think should be done via an indexer. At any moment I will want to be able to retrieve any element in the buffer by index. But keep in mind that from one moment to the next Element[n] may be different, as the Circular buffer fills up and rolls over. This isn't a stack, it's a circular buffer. Regarding "overflow": I would expect internally there would be an array holding the items, and over time the head and tail of the buffer will rotate around that fixed array. But that should be invisible from the user. There should be no externally-detectable "overflow" event or behavior. This is not a school assignment - it is most commonly going to be used for a MRU cache or a fixed-size transaction or event log.

  • Simple wxPython Frame Contents Resizing - Ratio?

    - by Wes
    I have a wxPython app with one frame and one panel. On that panel are a number of static boxes, each of which has buttons and textboxes. I have just begun reading about sizers, but they seem like they might be more than what I need, or it could that they are exactly what I need but I don't know how to use them correctly! The frame currently opens at 1920 x 1080. If the user drags the bottom right corner to resize the app, I just want everything to get smaller or larger as needed to keep the same size ratio. Is this possible? Thank you! edit: additional info: I used wxPython 2.8 and Boa to construct the GUI. I am contemplating trying another gui ide. So after reading some more about sizers, I am thinking about doing the following: add a gridsizer and basically divide my window's elements into rows and columns, then set each row and column's size as necessary until I achieve the original layout. Then I guess set the rows and columns to resize correctly? Is this a decent idea?

  • Same IL code, different output - how is it possible?

    - by Hali
    When I compile this code with mono (gmcs) and run it, it outputs -1 (both with mono and .Net framework). When I compile it with VS (csc), it outputs -1 when I run it with mono, and 0 when I run it with the .Net framework.

  • send email to list of users with different timezones?

    - by ylazez
    i use the following method to send email to list of users i want the (To) in each email to be for just the user only not all users i.e appears to the users that the email is sent to only him my guess is to loop on: message.addRecipients(Message.RecipientType.TO, address); then send the message right? , but this is a heavy process sending an email many times any ideas ? suppose that i have the timezone for each user and i want to send each user the message in his timzone, the same issue i guess setting sent date for each user in his timezone then sending the message, right ? the method is: try { Properties props = System.getProperties(); props.put("mail.smtp.host", "localhost"); // Get a mail session Session session = Session.getDefaultInstance(props, null); // Define a new mail message Message message = new MimeMessage(session); InternetAddress ia = new InternetAddress(); ia.setPersonal("MySite"); ia.setAddress(from); message.setFrom(ia); Address[] address = new Address[recievers.size()]; for (int i = 0; i < recievers.size(); i++) { address[i] = new InternetAddress(recievers.get(i)); } message.addRecipients(Message.RecipientType.TO, address); message.setSubject(subject); // Create a message part to represent the body text BodyPart messageBodyPart = new MimeBodyPart(); messageBodyPart.setContent(body, "text/html"); // use a MimeMultipart as we need to handle the file attachments Multipart multipart = new MimeMultipart(); // add the message body to the mime message multipart.addBodyPart(messageBodyPart); // Put all message parts in the message message.setContent(multipart); message.setSentDate(getCurrentDate()); // Send the message Transport.send(message); } catch (Exception ex) {}

  • Client-Side caching on IIS7 doesn't seem to work

    - by thomasbtv
    I have set content caching on a specific folder by following the local web.config method. I don't think it works, and I would like to fix this. I activate the cache using the IIS / HTTP Headers / Common headers feature. I set them to 1 day of expiration. I opened a page with Google Chrome in private navigation, and then open the Network tab in the console. The first time I load the page, everything loads from the site, obviously. If I refresh the page, I see 2 types of loading in the Network console: the files from Google and Facebook and such have a status of 200, and a size of (from cache). the files from the folder for which I set the caching have a status of 304 and their size is displayed. So, I guess the caching setting doesn't work? Or does the 304 response means that it's loaded from the cache? If they aren't, how can I make it work ? Thanks !

  • Memory Allocation increases in didSelectRowAtIndexPath

    - by mongeta
    Hello, I'm testing my App and in a very simple view, each time a tap on a UITableView row, my allocation overall bytes get higher and higher and never go downs. I don't have any special code there, so I created a new project from scratch with a very simple view, force one section and just three rows. In the didSelectRowAtIndexPath code do nothing, and fire it with instruments and memory allocation and, the memory goes up with every cell selection ... Is this normal behaviour ? thanks, regards, m.

  • Editing an UIImage

    - by wwrob
    I have an UIImage that I want to edit (say, make every second row of pixels black). Now I am aware of the functions that extract PNG or JPEG data from the image, but that's raw data and I have no idea how the png/jpeg files work. Is there a way I can extract the colour data from each pixel into an array? And then make a new UIImage using the data from the array?

  • Best way to unit test Collection?

    - by limc
    I'm just wondering how folks unit test and assert that the "expected" collection is the same/similar as the "actual" collection (order is not important). To perform this assertion, I wrote my simple assert API:- public void assertCollection(Collection<?> expectedCollection, Collection<?> actualCollection) { assertNotNull(expectedCollection); assertNotNull(actualCollection); assertEquals(expectedCollection.size(), actualCollection.size()); assertTrue(expectedCollection.containsAll(actualCollection)); assertTrue(actualCollection.containsAll(expectedCollection)); } Well, it works. It's pretty simple if I'm asserting just bunch of Integers or Strings. It can also be pretty painful if I'm trying to assert a collection of Hibernate domains, say for example. The collection.containsAll(..) relies on the equals(..) to perform the check, but I always override the equals(..) in my Hibernate domains to check only the business keys (which is the best practice stated in the Hibernate website) and not all the fields of that domain. Sure, it makes sense to check just against the business keys, but there are times I really want to make sure all the fields are correct, not just the business keys (for example, new data entry record). So, in this case, I can't mess around with the domain.equals(..) and it almost seems like I need to implement some comparators for just unit testing purposes instead of relying on collection.containsAll(..). Are there some testing libraries I could leverage here? How do you test your collection? Thanks.

  • Durandal Google Maps not showing properly

    - by user1891037
    Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code: define(['knockout', 'gmaps'], function (ko, gmaps) { return { displayName: 'Google Maps', myMap: ko.observable({ lat: ko.observable(32), lng: ko.observable(10)}), activate: function () { console.log('activate'); ko.bindingHandlers.map = { init: function (element, valueAccessor, allBindingsAccessor, viewModel) { console.log('init'); var mapObj = ko.utils.unwrapObservable(valueAccessor()); var latLng = new gmaps.LatLng( ko.utils.unwrapObservable(mapObj.lat), ko.utils.unwrapObservable(mapObj.lng)); var mapOptions = { center: latLng, zoom: 5, mapTypeId: gmaps.MapTypeId.ROADMAP}; mapObj.googleMap = new gmaps.Map(element, mapOptions); } } }, attached: function() { console.log('attached'); }, compositionComplete: function() { console.log('compositionComplete'); } }; }); And a very simple HTML code: <section> <div id="gmap-canvas" data-bind="map:myMap"></div> </section> I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa P.S. div size is defined in .CSS file. P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all. Thanks!

  • ScaleTransform transforms non-linearly

    - by Chris
    I am using scale transform to allow a user to resize a control. What happens though is that when you start to move the mouse the control jumps to a new size, and then scales oddly. The further you move your mouse from the starting location the larger the increase in size becomes. I expect its the way I calculate the scale to be applied. Here is the code: private void ResizeGrip_MouseDown(object sender, MouseButtonEventArgs e) { ResizeHandle.CaptureMouse(); //Get the initial coordinate cursor location on the window initBtmX = e.GetPosition(this).X; bottomResize = true; } private void ResizeGrip_MouseUp(object sender, MouseButtonEventArgs e) { bottomResize = false; ResizeHandle.ReleaseMouseCapture(); } private void ResizeGrip_MouseMove(object sender, MouseEventArgs e) { if( bottomResize == true) { //Get the new Y coordinate cursor location double newBtmX = e.GetPosition(this).X; //Get the smallest change between the initial and new cursor location double diffX = initBtmX - newBtmX; // Let our rectangle capture the mouse ResizeHandle.CaptureMouse(); double newWidth = e.GetPosition(this).X - diffX; double scaler = newWidth / ResizeContainer.ActualWidth; Console.WriteLine("newWidth: {0}, scalar: {1}", newWidth, scaler); if (scaler < 0.75 || scaler > 3) return; ScaleTransform scale = new ScaleTransform(scaler, scaler); ResizeContainer.LayoutTransform = scale; } }
