  • unicode data with custom font doesn't work properly in ipad

    - by David Ohanyan
    I am using custom font for label and string which I am getting from unicode characters. And the font is not changing. here is the snippet of my code: NSString* str = @"\u05D0\u05D1\u05D2"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; But when I write for example : NSString* str = @"label"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; The font effect is evident. Can someone explain what's here wrong?

  • optimal memory layout for read-only/write memory segments.

    - by aaa
    hello. Suppose I have two memory segments (equal size each, approximately 1kb in size) , one is read-only (after initialization), and other is read/write. what is the best layout in memory for such segments in terms of memory performance? one allocation, contiguous segments or two allocations (in general not contiguous). my primary architecture is linux Intel 64-bit. my feeling is former (cache friendlier) case is better. is there circumstances, where second layout is preferred? Thanks

  • Saving a screenshot of a window using C#, WPF, and DWM

    - by Evan
    This is a follow up question to this question The solution to the above uses DWM to display a thumbnail of an active window. If I understand correctly, it works by letting you specify the window handle of the application you want to view and then having you provide a window handle and a location on that window where windows should draw the contents of the target Window. Is there a way to render the window screen shot directly to BitmapImage or Image instead of directly drawing it somewhere in your window? (Basically to just grab a screen shot of the window - even if it's covered by another window - with out using an updating thumbnail.) Thanks for you help!

  • ScrollTo - toggle between min-height/fixed height

    - by Skoder
    Hi everyone, I'm trying to use the ScrollTo plugin, but I can't seem to get it working properly. I tried to view the source at the site I linked to but I'm trying to achieve something slightly different. I would like the window pane to change size according to the content (so the height would increase for longer text and would decrease for shorter text). However, when I supply a min-height (as opposed to a fixed height), the pane automatically changes to the maximum height when the page is loaded. So if I have something set to margin-top:1000px;, the pane will be 1000px in size regardless of what tab is currently displaying. The fix would be to use height instead, but that would mean that the window won't expand in height and the user would have to scroll. I got my code from viewing the source on the ScrollTo page, but I also tried this tutorial code. Thanks for any help

  • use jquery to toggle disabled state with a radio button

    - by hbowman
    I want to toggle two radio buttons and select fields based on which radio button is selected. I have the jQuery working, but want to know if there is a way to make it more efficient. Seems like quite a few lines for the simple goal I am trying to achieve. Here are the requirements: when the page loads, #aircraftType should be checked and #aircraftModelSelect should be grayed out (right now, the "checked" is being ignored by Firefox). If the user clicks either #aircraftType or #aircraftModel, the opposite select field should become disabled (if #aircraftModel is checked, #aircraftTypeSelect should be disabled, and vise versa). Any help on optimizing this code is appreciated. Code is up on jsfiddle too: http://jsfiddle.net/JuRKn/ $("#aircraftType").attr("checked"); $("#aircraftModel").removeAttr("checked"); $("#aircraftModelSelect").attr("disabled","disabled").addClass("disabled"); $("#aircraftType").click(function(){ $("#aircraftModelSelect").attr("disabled","disabled").addClass("disabled"); $("#aircraftTypeSelect").removeAttr("disabled").removeClass("disabled"); }); $("#aircraftModel").click(function(){ $("#aircraftTypeSelect").attr("disabled","disabled").addClass("disabled"); $("#aircraftModelSelect").removeAttr("disabled").removeClass("disabled"); }); HTML <div class="aircraftType"> <input type="radio" id="aircraftType" name="aircraft" checked /> <label for="aircraftType">Aircraft Type</label> <select size="6" multiple="multiple" id="aircraftTypeSelect" name="aircraftType"> <option value="">Light Jet</option> <option value="">Mid-Size Jet</option> <option value="">Super-Mid Jet</option> <option value="">Heavy Jet</option> <option value="">Turbo-Prop</option> </select> </div> <div class="aircraftModel"> <input type="radio" id="aircraftModel" name="aircraft" /> <label for="aircraftModel">Aircraft Model</label> <select size="6" multiple="multiple" id="aircraftModelSelect" name="aircraftModel"> <option value="">Astra SP</option> <option value="">Beechjet 400</option> <option value="">Beechjet 400A</option> <option value="">Challenger 300</option> <option value="">Challenger 600</option> <option value="">Challenger 603</option> <option value="">Challenger 604</option> <option value="">Challenger 605</option> <option value="">Citation Bravo</option> </select> </div>

  • C++ Template Classes Circular Dependency Problem

    - by TomWij
    We have two classes: template<typename T, typename Size, typename Stack, typename Sparse> class Matrix and template<typename T, typename Size> class Iterator Matrix should be able to return begin and end iterators and Iterator will keep a referrence to the Matrix to access the elements via it's interface. We don't want Iterator to depend on the internal storage of the Matrix to prevent coupling. How can we solve this cyclic dependency problem? (The internal Storage class has the same template parameters as the Matrix class and the same access procedures as the Matrix itself)

  • UINavigationController (drawRect:)

    - by ludo
    Hi, I created an application with a TabBarController, 4 TabBarItems and every TabBarItem have is own NavigationController file (everything created in IB). I'm using the drawRect function to design my navigationBar: @implementation UINavigationBar (customImage) -(void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed:@"MyImage.png"]; [image drawInRect:CGRectMake(0,0, self.frame.size.width,self.frame.size.height)]; } @end The problem is that the NavigationBar change for every ViewController inside my app, what I want is only draw the NavigationBar for one TabBarItem only and use the default navigationBar for other controller. How to do that? Thanks,

  • Understanding the workings of equals and hashCode in a HashMap

    - by andandandand
    I have this test code: import java.util.*; class MapEQ { public static void main(String[] args) { Map<ToDos, String> m = new HashMap<ToDos, String>(); ToDos t1 = new ToDos("Monday"); ToDos t2 = new ToDos("Monday"); ToDos t3 = new ToDos("Tuesday"); m.put(t1, "doLaundry"); m.put(t2, "payBills"); m.put(t3, "cleanAttic"); System.out.println(m.size()); } } class ToDos{ String day; ToDos(String d) { day = d; } public boolean equals(Object o) { return ((ToDos)o).day == this.day; } // public int hashCode() { return 9; } } When // public int hashCode() { return 9; } is uncommented m.size() returns 2, when it's left commented it returns three. Why?

  • can these be made unambiguous

    - by R Samuel Klatchko
    I'm trying to create a set of overloaded templates for arrays/pointers where one template will be used when the compiler knows the size of the array and the other template will be used when it doesn't: template <typename T, size_t SZ> void moo(T (&arr)[SZ]) { ... } template <typename T> void moo(T *ptr) { ... } The problem is that when the compiler knows the size of the array, the overloads are ambiguous and the compile fails. Is there some way to resolve the ambiguity (perhaps via SFINAE) or is this just not possible.

  • Why don't my scrollbars work properly when programmatically hiding rows in silverlight Datagrid?

    - by Luke Vilnis
    I have a Silverlight datagrid with custom code that allows for +/- buttons on the lefthand side and can display a table with a tree structure. The +/- buttons are bound to a IsExpanded property on my ViewModelRows, as I call them. The visibility of rows is bound to an IsVisible property on the ViewModelRows which is determined based on whether or not all of the parent rows are expanded. Straightforward enough. This code works fine in that if I scroll up and down the grid with PageUp/PageDown or the arrow keys, all the right rows are hidden and everything has the right structure and I can play with the +/- buttons to my hearts content. However, the vertical scroll bar on the right hand side, although it starts off the correct size and it scrolls through the rows smoothly, when I collapse rows and then re-expand them, doesn't go back to its correct size. The scrollbar can still usually be moved around to scroll through the whole collection, but because it is too big, once the bar moves to the bottom, there are still more rows to go through and it sort of jerkily shoots all the way down to the bottom or sometimes fails to scroll at all. This is pretty hard to describe so I included a screenshot with the black lines drawn on to show the difference in scrollbar length even though the two grids have the same number of rows expanded. I think this might be a bug related to the way the Datagrid does virtualization of rows. It seems to me like it isn't properly keeping track of how tall each row is supposed to be when expansion states change. Is there a way to programmatically "poke" (read hack) it to recalculate its scrollbar size on LoadingRow or something ugly like that? I'd include a code sample but there's 2 c# files and 1 xaml file so I wanted to see if anyone else has heard of this sort of issue before I try to make it reproducible in a self-contained way. Once again, scrolling with the arrow keys works fine so I'm pretty sure the underlying logic and binding is working, there's just some issue with the row height not being calculated properly. Since I'm a new user, it won't let me use image tags so here's the link to a picture of the problem: http://img210.imageshack.us/img210/8760/messedupscrollbars.png

  • "The usage of semaphores is subtly wrong"

    - by Hoonose
    This past semester I was taking an OS practicum in C, in which the first project involved making a threads package, then writing a multiple producer-consumer program to demonstrate the functionality. However, after getting grading feedback, I lost points for "The usage of semaphores is subtly wrong" and "The program assumes preemption (e.g. uses yield to change control)" (We started with a non-preemptive threads package then added preemption later. Note that the comment and example contradict each other. I believe it doesn't assume either, and would work in both environments). This has been bugging me for a long time - the course staff was kind of overwhelmed, so I couldn't ask them what's wrong with this over the semester. I've spent a long time thinking about this and I can't see the issues. If anyone could take a look and point out the error, or reassure me that there actually isn't a problem, I'd really appreciate it. I believe the syntax should be pretty standard in terms of the thread package functions (minithreads and semaphores), but let me know if anything is confusing. #include <stdio.h> #include <stdlib.h> #include "minithread.h" #include "synch.h" #define BUFFER_SIZE 16 #define MAXCOUNT 100 int buffer[BUFFER_SIZE]; int size, head, tail; int count = 1; int out = 0; int toadd = 0; int toremove = 0; semaphore_t empty; semaphore_t full; semaphore_t count_lock; // Semaphore to keep a lock on the // global variables for maintaining the counts /* Method to handle the working of a student * The ID of a student is the corresponding minithread_id */ int student(int total_burgers) { int n, i; semaphore_P(count_lock); while ((out+toremove) < arg) { n = genintrand(BUFFER_SIZE); n = (n <= total_burgers - (out + toremove)) ? n : total_burgers - (out + toremove); printf("Student %d wants to get %d burgers ...\n", minithread_id(), n); toremove += n; semaphore_V(count_lock); for (i=0; i<n; i++) { semaphore_P(empty); out = buffer[tail]; printf("Student %d is taking burger %d.\n", minithread_id(), out); tail = (tail + 1) % BUFFER_SIZE; size--; toremove--; semaphore_V(full); } semaphore_P(count_lock); } semaphore_V(count_lock); printf("Student %d is done.\n", minithread_id()); return 0; } /* Method to handle the working of a cook * The ID of a cook is the corresponding minithread_id */ int cook(int total_burgers) { int n, i; printf("Creating Cook %d\n",minithread_id()); semaphore_P(count_lock); while ((count+toadd) <= arg) { n = genintrand(BUFFER_SIZE); n = (n <= total_burgers - (count + toadd) + 1) ? n : total_burgers - (count + toadd) + 1; printf("Cook %d wants to put %d burgers into the burger stack ...\n", minithread_id(),n); toadd += n; semaphore_V(count_lock); for (i=0; i<n; i++) { semaphore_P(full); printf("Cook %d is putting burger %d into the burger stack.\n", minithread_id(), count); buffer[head] = count++; head = (head + 1) % BUFFER_SIZE; size++; toadd--; semaphore_V(empty); } semaphore_P(count_lock); } semaphore_V(count_lock); printf("Cook %d is done.\n", minithread_id()); return 0; } /* Method to create our multiple producers and consumers * and start their respective threads by fork */ void starter(int* c){ int i; for (i=0;i<c[2];i++){ minithread_fork(cook, c[0]); } for (i=0;i<c[1];i++){ minithread_fork(student, c[0]); } } /* The arguments are passed as command line parameters * argv[1] is the no of students * argv[2] is the no of cooks */ void main(int argc, char *argv[]) { int pass_args[3]; pass_args[0] = MAXCOUNT; pass_args[1] = atoi(argv[1]); pass_args[2] = atoi(argv[2]); size = head = tail = 0; empty = semaphore_create(); semaphore_initialize(empty, 0); full = semaphore_create(); semaphore_initialize(full, BUFFER_SIZE); count_lock = semaphore_create(); semaphore_initialize(count_lock, 1); minithread_system_initialize(starter, pass_args); }

  • Configuring the expiry time for the messages destined to the "Expired message address" in Hornetq

    - by Rohit
    I have configured a message expiry destination in Hornetq as below <address-setting match="#"> <dead-letter-address>jms.queue.error</dead-letter-address> <expiry-address>jms.queue.error</expiry-address> <max-delivery-attempts>3</max-delivery-attempts> <redelivery-delay>2000</redelivery-delay> <max-size-bytes>10485760</max-size-bytes> <message-counter-history-day-limit>10</message-counter-history-day-limit> <address-full-policy>BLOCK</address-full-policy> <redistribution-delay>60000</redistribution-delay> </address-setting> And the messages do get redirected to the expiry address once the expiration time is exceeded. These messages live indefinitely on the expiry address, Is there a way to provide a expiry time for these messages so they live only limited time on the expiry address?

  • Why is my asp.net mvc form POSTing instead of GETting?

    - by quakkels
    My code is straightforward enough: <% using(Html.BeginForm(FormMethod.Get)) %> <% { %> Search for in Screen Name and Email: <%: Html.TextBox("keyword", Request.QueryString["keyword"]) %> <button type=submit>Search</button> <% } %> The issue I'm running into is that when I submit this form, the values are not added to the querystring. Instead, it appears that the form is submitting by a post request. When I look at the generated HTML, I have this: <form action="/find/AdminMember/MemberList" method="post"> Search for in Screen Name and Email: <input id="keyword" name="keyword" type="text" value="" /> <button type=submit>Search</button> </form> Does anyone know why? This seems pretty simple and straighforward to me.

  • Hibernate Lazy init exception in spring scheduled job

    - by Noam Nevo
    I have a spring scheduled job (@Scheduled) that sends emails from my system according to a list of recipients in the DB. This method is annotated with the @Scheduled annotation and it invokes a method from another interface, the method in the interface is annotated with the @Transactional annotation. Now, when i invoke the scheduled method manually, it works perfectly. But when the method is invoked by spring scheduler i get the LazyInitFailed exception in the method implementing the said interface. What am I doing wrong? code: The scheduled method: @Component public class ScheduledReportsSender { public static final int MAX_RETIRES = 3; public static final long HALF_HOUR = 1000 * 60 * 30; @Autowired IScheduledReportDAO scheduledReportDAO; @Autowired IDataService dataService; @Autowired IErrorService errorService; @Scheduled(cron = "0 0 3 ? * *") // every day at 2:10AM public void runDailyReports() { // get all daily reports List<ScheduledReport> scheduledReports = scheduledReportDAO.getDaily(); sendScheduledReports(scheduledReports); } private void sendScheduledReports(List<ScheduledReport> scheduledReports) { if(scheduledReports.size()<1) { return; } //check if data flow ended its process by checking the report_last_updated table in dwh int reportTimeId = scheduledReportDAO.getReportTimeId(); String todayTimeId = DateUtils.getTimeid(DateUtils.getTodayDate()); int yesterdayTimeId = Integer.parseInt(DateUtils.addDaysSafe(todayTimeId, -1)); int counter = 0; //wait for time id to update from the daily flow while (reportTimeId != yesterdayTimeId && counter < MAX_RETIRES) { errorService.logException("Daily report sender, data not ready. Will try again in one hour.", null, null, null); try { Thread.sleep(HALF_HOUR); } catch (InterruptedException ignore) {} reportTimeId = scheduledReportDAO.getReportTimeId(); counter++; } if (counter == MAX_RETIRES) { MarketplaceServiceException mse = new MarketplaceServiceException(); mse.setMessage("Data flow not done for today, reports are not sent."); throw mse; } // get updated timeid updateTimeId(); for (ScheduledReport scheduledReport : scheduledReports) { dataService.generateScheduledReport(scheduledReport); } } } The Invoked interface: public interface IDataService { @Transactional public void generateScheduledReport(ScheduledReport scheduledReport); } The implementation (up to the line of the exception): @Service public class DataService implements IDataService {

  • Drawing a bitmap in a canvas after calling setBitmap doesn't work

    - by kodbar_k
    I'm drawing a bitmap in a canvas and i want to have the result in a new bitmap, but i still have a black screen as result. This is my code, part of the onDraw(Canvas canvas) method : if (bitmapTemplate == null) { canvasBis = new Canvas(); bitmapTemplate = Bitmap.createBitmap(canvas.getWidth()+30,canvas.getHeight(),Bitmap.Config.ARGB_8888); drawZones(canvasBis,bitmapTemplate); } bitmapRes = Bitmap.createBitmap(canvas.getWidth()+30,canvas.getHeight(),Bitmap.Config.ARGB_8888); canvas.setBitmap(bitmapRes); canvas.drawBitmap(bitmapTemplate, matrix, null); My goal is to have a new bitmap (bitmapRes) by applying a matrix on an existing bitmap (bitmapTemplate). With this code i alway have a black screen, but when i remove the line canvas.setBitmap(bitmapRes) i have a result but not in a new bitmap. any ideas please ? Maybe transparency ? Thanks in advance. drawZones draws some zones in bitmapTemplate.

    Hello, In my website, there are 2 steps : I get values from another domain with AJAX, it's numbers 100% working Then, i want to display those numbers in stars with this plugin (http://stackoverflow.com/questions/1987524/turn-a-number-into-star-rating-display-using-jquery-and-css) The error : the stars plugin does not work for the value i recieve from my ajax request, but it's working for my values for my domain which are not JS manipulated you can see a demo here http://www.esl.eu/fr/test/test_atome/?killcache=true PS: the data in ajax are provided in JSON-P so i wrote a parser which look like this: jQuery.ajax({ type: "get", dataType: "jsonp", url: "http://www.foo.com/", data: {demandeur: "monkey" }, cache: true, success: function(data, textStatus, XMLHttpRequest){ var obj = null, length = data.length; for (var i = 0; i < length; i++) { widget = "<p>AVERAGES<p>"; widget += "<p><span class='stars'>"; widget += data[i].services; widget += "</span></p>"; widget += "<p><span class='stars'>"; widget += data[i].qualite; widget += "</span></p>"; jQuery('#gotserv').html(widget); } } }); }); Then i have the star plugin after this function : $.fn.stars = function() { $(this).each(function() { // Get the value var val = parseFloat($(this).html()); // Make sure that the value is in 0 - 5 range val = val 5 ? 5 : (val < 0 ? 0 : val); // Calculate physical size var size = 16 * val; // Create stars holder var stars = $(''); // Adjust yellow stars' width stars.find('span').width(size); // Replace the numerical value with stars $(this).replaceWith(stars); }); I hope you understand, i don't know if i'm clear Thank you

  • How to save file and read

    - by Jessy
    Hello everyone, I create a program that place random image in grid layout format. The size of the grid layout is 6 x 6 = 36. Only 10 were filled with images (each image was different) and the rest were empty. freeimagehosting.net/uploads/bfb7e85f63.jpg How can I save it to a file and read it again, so it will display the same images with same placement on the grid? Here is the code that I used to save the images: //image file String []arrPic = {"pic1.jpg","pic2.jpg","pic3.jpg","pic4.jpg","pic5.jpg","pic6.jpg","pic7.jpg","pic8.jpg","pic9.jpg","pic10.jpg",,"pic11.jpg","pic12.jpg","pic13.jpg"}; ArrayList<String> pictures = new ArrayList<String>(Arrays.asList(arrPic)); ArrayList<String> file = new ArrayList<String>(); JPanel pDraw = new JPanel(new GridLayout(6,6,2,2)); ... //fill all grids with empty label for (int i =0; i<(6*6); i++){ JLabel lbl = new JLabel(""); pDraw.add(lbl); } ... //Choose random box to be filled with images for(int i=0; i<10; i++){ Boolean number = true; while(number){ int n = rand.nextInt(35); if(!(arraylist.contains(n))) number = false; arraylist.add(n); } //fill the grids with images for(int i=0; i<arraylist.size(); i++){ //select random image from arraylist int index = rand.nextInt (pictures.size()); String fileName = (String) pictures.get(index ); //find the image file icon = createImageIcon(fileName); //save the file in a new file file.add(fileName); //rescaled the image int x = rand.nextInt(50)+50; int y = rand.nextInt(50)+50; Image image = icon.getImage().getScaledInstance(x,y,Image.SCALE_SMOOTH); icon.setImage(image); //remove empty label and replace it with an image int one = (Integer) arraylist.get(i); pDraw.remove(one); final JLabel label; pDraw.add(label,one); }

  • Which Python XML library should I use?

    - by PulpFiction
    Hello. I am going to handle XML files for a project. I had earlier decided to use lxml but after reading the requirements, I think ElemenTree would be better for my purpose. The XML files that have to be processed are: Small in size. Typically < 10 KB. No namespaces. Simple XML structure. Given the small XML size, memory is not an issue. My only concern is fast parsing. What should I go with? Mostly I have seen people recommend lxml, but given my parsing requirements, do I really stand to benefit from it or would ElementTree serve my purpose better?

  • How to write stored procedures to separate files with mysqldump?

    - by Jader Dias
    The mysqldump option --tab=path writes the creation script of each table in a separate file. But I can't find the stored procedures, except in the screen dump. I need to have the stored procedures also in separate files. The current solution I am working on is to split the screen dump programatically. Is there a easier way? The code I am using so far is: mysqldump -p$PASSWORD --routines --skip-dump-date --no-create-info --no-data --skip-opt $DATABASE > $BACKUP_PATH/$DATABASE.sql mysqldump -p$PASSWORD --tab=$BACKUP_PATH --skip-dump-date --no-data --skip-opt $DATABASE

  • Iphone UIView implementation

    - by Joo Park
    How does one code this scenerio in iphone sdk? In an expense app, when you want to add an expense, this view comes up. After selecting "Clothing," another view slides up with a UIPickerView control that has a "done" button which will dismiss the UIPickerView. Below is a screen shot after hitting "Clothing." I'm trying to figure out how one would slide up the UIPickerView half way up the screen with a "done" button on top of the "New Expense" view? thank you in advance!

  • Memory footprint of a parsed XML file in Classic ASP?

    - by Pete Duncanson
    Anyone know of a way to find out the amount of memory/size of a XMLDocument once it has parsed a XML file? I've been doing "beer mat" calculations so far but have been asked to come up with some more legit numbers through monitoring some how. I need to create about 1500 XML files (via FreeThreadedXMl-DOM object), which verge between 3-9K in size and store them in Application vars but our SysAdmin is worried about us gobbling up too much memory. Other than the crude method of booting up a fresh IIS instance and then loading everything in and monitoring before and after memory usage in Task Manager I can't think of a way of doing it with a bit more accuracy.

  • Ouput all the page's media queries in a list

    - by alecrust
    Using JavaScript, what would be the best way to output a list containing all media queries that are being applied to the current page. I assume this would need to filtering to find embedded media queries i.e. <link rel="stylesheet" media="only screen and (min-width: 30em)" href="/css/30em.css"> as well as media queries located in CSS files, i.e. @media only screen and (min-width: 320px) {} An example output of what I'm looking for: <p>There are 3 media queries loaded on this page</p> <ol> <li>30em</li> <li>40em</li> <li>960px</li> </ol>

  • taskbar-free window manager

    - by 7vies
    I'm looking for a window manager that is not based on the "standard" taskbar (which I find a poor idea and I'm completely tired of). I'm aware of tiling window managers and improvements in last versions of operating systems, but I can't find what I need. I suppose that any window takes the whole screen (or can be tiled), and I imagine switching between windows like that: on a hotkey or mouse hot zone the screen becomes a task switcher where tasks are organized in a somewhat convenient manner. Well, it's a bit like a taskbar with autohide, but I think there could be some more convenient ideas than simply stacking icons and descriptions... It is also supposed to be lightweight enough, for example to run on a netbook. Any suggestions?

  • Grails validateable not work for non-persistent domain class

    - by Hoàng Long
    I followed the instruction here: http://www.grails.org/doc/latest/guide/7.%20Validation.html and added into config.groovy: grails.validateable.classes = [liningtest.Warm'] Then added in src/groovy/Warm.groovy (it's a non-persistent domain class): package liningtest import org.codehaus.groovy.grails.validation.Validateable class Warm { String name; int happyCite; Warm(String n, int h) { this.name = n; this.happyCite = h; } static constraints = { name(size: 1..50) happyCite(min: 100) } } But it just doesn't work (both "blank false" & "size: 0..25") for the "hasErrors" function. It always returns false, even when the name is 25. Is this a Grails bug, if yes, is there any work-around? I'm using Grails 1.3.3 UPDATE: I have updated the simplified code. And now I know that constraint "size" can't be used with "blank", but still does not work. My test class in test/unit/liningtest/WarmTests.groovy package liningtest import grails.test.* class WarmTests extends GrailsUnitTestCase { protected void setUp() { super.setUp() } protected void tearDown() { super.tearDown() } void testSomething() { def w = new Warm('Hihi', 3) assert (w.happyCite == 3) assert (w.hasErrors() == true) } } And the error I got: <?xml version="1.0" encoding="UTF-8" ?> <testsuite errors="1" failures="0" hostname="evolus-50b0002c" name="liningtest.WarmTests" tests="1" time="0.062" timestamp="2010-12-16T04:07:47"> <properties /> <testcase classname="liningtest.WarmTests" name="testSomething" time="0.062"> <error message="No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode()" type="groovy.lang.MissingMethodException">groovy.lang.MissingMethodException: No signature of method: liningtest.Warm.hasErrors() is applicable for argument types: () values: [] Possible solutions: hashCode() at liningtest.WarmTests.testSomething(WarmTests.groovy:18) </error> </testcase> <system-out><![CDATA[--Output from testSomething-- ]]></system-out> <system-err><![CDATA[--Output from testSomething-- ]]></system-err> </testsuite> UPDATE 2: When I don't use Unit test, but try to call hasErrors in the controller, it runs but return false value. (hasErrors return false with Warm('Hihi', 3) ). Does anyone has a clue?

  • Looking for help with a design for a simple C# calendar app.

    - by Vladislav
    As a personal project, I'm putting together a C# WPF calendar. I'm stuck on coding the calendar screen - specifically, the 5x7 grid of days. I've first tried to code it using elements like Panels, Labels, and Buttons. I've decided that was too cumbersome. I've then decided to use GDI to draw the calendar myself. I now have a wonderful layout - but I'm not sure how to handle interactive regions of the calendar. (Say, Previous/Next month, clicking on any particular day...) After rendering the calendar screen, should I be creating button objects for all those tasks, and assigning onClick handlers to them? Or is there an alternative solution? Thanks in advance. -Vladislav
