  • jQuery datepicker validation message issue

    - by Abhishek
    Hi, I'm using the jquery datepicker plugin at http://plugins.jquery.com/project/datepick with the datepicker validation plugin. <script id="frmValidation" type="text/javascript"> $(document).ready(function(){ var validator = $("#frmTest").validate({ rules:{ fname: "required", dobPicker: "required" }, messages:{ fname: "Please enter a name", dobPicker: "Select a date" }, }); $('#dobPicker').datepick(); $.datepick.setDefaults({showOn: 'both', dateFormat: 'dd-mm-yy', yearRange:'1900:2010'}); }); </script> And the body of the document is as follows : <form id="frmTest" action="" method="post"> <div id="error-list"></div> <div class="form-row"> <span class="label"><label for="fname">Name</label></span> <input type="text" name="fname" /> </div> <div class="form-row"> <span class="label"><label for="dobPicker">DOB</label></span> <input type="text" id="dobPicker" name="dobPicker" style="margin-left: 4px;"/> </div> <div class="form-row"> <input type="submit" name="submit" value="submit"/> </div> </form> The form validates the first time but the error message for the datepicker does not disappear immediately a date is selected.. however it goes away if the date is selected the second time. Any help to make it go the first time a date is selected will be appreciated

  • Memory leak when using Workflow 4.0 SqlWorkflowInstanceStore and PersistableIdleAction.Unload

    - by Rohland
    Hi, This particular problem is driving me nuts. I wonder if anyone has experienced a similar problem. If I load up a workflow then unload it and perform a memory snapshot then the result is predictable - my workflow is no longer in memory. However, if I load up a workflow and set the PersistableIdle action to PersistableIdleAction.Unload and let the workflow idle the workflow remains in memory even though the Unload action fires. I used ANTS Memory Profiler to debug this issue. This is the object retention graph outputted showing that an internal object is hanging onto my workflow instance. Can anyone else verify this problem? My code amounts to the following: Create SqlWorkflowInstanceStore and setup lock owner handle -- At this point I take a memory snapshot Create an instance of Workflow1 Set the PersistableIdle action Apply the instancestore to Workflow1 Setup action event handlers for Idle, Unload, UnhandledException etc. Persist the workflow instance Run the workflow instance Wait for instance to idle (caused by Delay activity) Ensure the Unload action is fired -- At this point I take a second memory snapshot From the above image, it is clear that the only object referencing Workflow1 is some internal event handlers result which I have no ability to dispose of. Any clues?

  • Android: Dialog themed activity not visible

    - by Vincent
    I have an activity which, when started, needs to check if the user is authenticated. If not, I need to display an interface to authenticate. I do this with another activity, which has a dialog theme, and I start it in onResume() with flags NO_HISTORY and EXCLUDE_FROM_RECENTS. Everything works fine when starting the application for the first time. But I have a feature that resets login after some time, if the user is not in an activity. When I test this, I start the applicatio, enter the password, then move back to home. Then when I enter the application again, the background darkens as if the dialog would show, but it doesn't. At this point, if I press the back button, the darkening from the background activity disappears for a second, then the dialog finally appears. I used logcat to investigate the case, and the activity lifecycle functions get called properly: //For the first start: onCreate background activity onStart background activity onResume background activity onPause background activity onCreate dialog onStart dialog onResume dialog //Enter password onPause dialog onResume background activity onStop dialog onDestroy dialog //navigating to homescreen onPause background activity onStop background activity //starting again onRestart background activity onStart background activity onResume background activity onPause background activity onCreate dialog onStart dialog onResume dialog //no dialog shown, only darkened background activity recieving no input //pressing back button onPause dialog onResume background activity onPause background activity onCreate NEW dialog onStart NEW dialog onResume NEW dialog onStop OLD dialog onDestroy OLD dialog //now the dialog is properly shown //entering password onPause NEW dialog onResume background activity onStop NEW dialog onDestroy NEW dialog Using the SINGLE_TOP flag makes no change. However, if I remove the dialog theme from the dialog activity, it IS shown after the restart. So far I didn't want to use a Dialog instead of an Activity, because I consider them problematic sometimes and less encapsulated and this part has to be quite secure. You may be able to convince me though.. Thank you in advance!

  • WPF Toolkit Charting and IndependentValueBinding, IndependentValuePath

    - by Joel Barsotti
    So I'm having a problem with the charting engine from the WPF toolkit. We haven't moved our data to a proper object model, so the ItemSource is backed with a DataView. First attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValueBinding="{Binding Path=TargetSeries_X}" DependentValueBinding="{Binding Path=TargetSeries_X}" /> This crashes because, I believe, it thinks the bindings are the values to plot or some sort of mismatch. Second attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="{Binding Path=TargetSeries_X}" DependentValuePath="{Binding Path=TargetSeries_X}" /> This crashes during the init step becaue the Path properties aren't backed with dependency properties and therefore cannot be bound. Third attempt <chartingToolkit:ScatterSeries x:Name="TargetSeries" DataPointStyle="{StaticResource TargetStyle}" ItemsSource="{Binding Path=TargetSeriesData}" IndependentValuePath="targetFooXColumnName" DependentValuePath="targetFooYColumnName" /> Now this works! But I wanted to use the binding so I can switch from using the targetFooXColumnName to the targetFooBarXColumnName. So this solution will cause a whole lot of hacky looking code to switch the Path's manually. Anyway to fix this? Can I use some sort of convertor to get the Binding properties to correctly pull the data from the columns in the DataView? Thanks, Joel

  • Median Filter a bi-level image with JAI

    - by Mark
    I'd like to apply a Median Filter to a bi-level image and output a bi-level image. The JAI median filter seems to output an RGB image, which I'm having trouble downconverting back to bi-level. Currently I can't even get the image back into gray color-space, my code looks like this: BufferedImage src; // contains a bi-level image ParameterBlock pb = new ParameterBlock(); pb.addSource(src); pb.add(MedianFilterDescriptor.MEDIAN_MASK_SQUARE); pb.add(3); RenderedOp result = JAI.create("MedianFilter", pb); ParameterBlock pb2 = new ParameterBlock(); pb2.addSource(result); pb2.add(new double[][]{{0.33, 0.34, 0.33, 0}}); RenderedOp grayResult = JAI.create("BandCombine", pb2); BufferedImage foo = grayResult.getAsBufferedImage(); This code hangs on the grayResult line and appears not to return. I assume that I'll eventually need to call the "Binarize" operation in JAI. Edit: Actually, the code appears to be stalling once I call getAsBufferedImage(), but returns nearly instantly when the second operation ("BandCombine") is removed. Is there a better way to keep the Median Filtering in the source color domain? If not, how do I downconvert back to binary?

  • Is VB Really Case Insensitive?

    - by Otaku
    I'm not trying to start an argument here, but for whatever reason it's typically stated that VB is case insensitive and C languages aren't (and somehow that is a good thing). But here's my question: Where exactly is VB case insensitive? When I type... Dim ss As String Dim SS As String ...into the VS2008 IDE the second one has a warning of "Local variable 'SS' is already declared in the current block". In VBA VBE, it doesn't immediately kick an error, but rather just auto-corrects the case. Am I missing something here with this argument that VB is not case sensitive? (Also, if you know or care to answer, why would that be a bad thing?) EDIT: Why am I even asking this question? I've used VB in many of it's dialects for years now, sometimes as a hobbyist, sometimes for small business-related programs in a workgroup. As of the last 6 months I've been working on a big project, much bigger than I anticipated. Much of the sample source code out there is in C#. I don't have any burning desire to learn C#, but if there are things I'm missing out on that C# offers that VB doesn't (an opposite would be VB.NET offers XML Literals), then I'd like to know more about that feature. So in this case, it's often argued that C languages are case sensitive and that's good and VB is case insensitive and that is bad. I'd like to know A) how exactly is VB case insensitive because every single example in the code editor becomes case sensititive (meaning case gets corrected) whether I want it or not and B) is this compelling enough for me to consider moving to C# if VB.NET case is somehow limiting what I could do with code?

  • Excel export displaying '#####...'

    - by Cypher
    I'm trying to export an Excel database into .txt (Tab Delimited), but some of my cells are quite large. When I export into a txt some of the cells are exported as '#######....' which is surprisingly useless. Has this happened to anyone else? Do you know an easy fix?

  • Javadoc through Ant task with {@inheritDoc} from J2SE classes

    - by miorel
    I generate documentation for a project using an Ant task. In several places, I wanted to inherit documentation from the standard classes, so I used {@inheritDoc} which allowed me to see the Javadoc in Eclipse, but it wouldn't show up in the HTML files. The problem was that I hadn't included the unzipped src.zip (J2SE source) in the sourcepath. Having fixed that, I now get several hundred warnings about the use of Sun proprietary API in files like lib/jdk-src/java/lang/Class.java. Is there any way to suppress these warnings? It's hard to find relevant problems in this mess. A possible solution I thought of was to run the Javadoc task once without including the J2SE source in the sourcepath, which will reveal any real issues. Then I can run Javadoc a second time with the J2SE source included, discarding the output altogether, which will produce documentation with properly-working {@inheritDoc}s. I'm not entirely sure about the best way to accomplish this in Ant, not to mention that running Javadoc twice would be a dirty fix. Any suggestions?

  • jQuery draggable + droppable: how to snap dropped element to dropped-on element

    - by 10goto10
    I have my screen divided into two DIVs. In the left DIV I have a few 50x50 pixel DIVs, in the right DIV I have an empty grid made of 80x80 LIs. The DIVs on the left are draggable, and once dropped on a LI, they should snap to center of that LI. Sounds simple, right? I just don't know how to get this done. I tried by manipulating the dropped DIV's top and left CSS properties to match those of the LI they're dropped into, but the left and top properties are relative to the left DIV. How can I best have the dropped element snap to the center of the element it's dropped into? That's gotta be simple, right? Edit: I'm using jQuery UI 1.7.2 with jQuery 1.3.2. Edit 2: For whoever else has this problem, this is how I fixed it: I used Keith's solution of removing the dragged element and placing it inside the dropped-on element in the drop callback of the droppable plugin: function gallerySnap(droppedOn, droppedElement) { $(droppedOn).html('<div class="drop_styles">'+$(droppedElement).html()+'</div>' ); $(droppedElement).remove(); } I don't the dropped element to be draggable again, but if you do, just bind draggable to it again. For me this method also solved the problem I had when positioning the dropped elements (which would be relative to the left DIV) and scrolling inside the second DIV. (Elements would remain fixed on page, now they scroll along). I did play with the snap options to make it look good while dragging, so thanks to karim79 for that suggestion. I probably won't win any Awesome Code prizes with this, so if you see room for improvement, please share!

  • Oracle command hangs when using view for "WHERE x IN..." subquery

    - by Calvin Fisher
    I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?

  • In Reporting Services how to filter drop down parameter list in based on other selected parameter?

    - by Lee Englestone
    Question In a Reporting Services Report, How do I filter a second drop down list of cars to only show cars whose ManufacturerId is equal the selected Manufacturer (from the first drop down list)? Report Datasets I have 2 datasets. Dataset 1. A list of Manufacturers. From a stored procedure Report_Manufacturers_P Dataset 2. A list of Cars, including a column called Manufacturers id. From a stored procedure Report_Cars_P Report Parameters On the Report I have 2 Parameters. Parameter 1. ManufacturerId. Set from A drop down list of Manufacturers (DataSet 1). Parameter 2. CarId. Set from A drop down list of Cars (DataSet 2). I've tried.. Creating another sproc called Report_Manufacturer_Cars_P that takes the ManufacturerId as an integer and returns a list of cars made by that manufacturer. Any Ideas. As selecting a Manufacturer doesn't seem to want to kick off anything that filters the Car list? Thanks in advance, -- Lee

  • FileDialog DoubleClick Behavior

    - by Shaun Hamman
    While developing a WinForms application, I came across what I believe is a bug in the OpenFileDialog and SaveFileDialog controls. A Google search turned up a single other person who noticed the same issue, but neither a solution nor a workaround was provided. You can view this thread at: http://bytes.com/topic/visual-basic-net/answers/389470-open-file-dialog-picturebox-click-event. I have a custom control on my form that handles the MouseDown event. If I doubleclick a file in a FileDialog control while the mouse is over this control (with the dialog between them, obviously), the MouseDown event gets triggered. I don't think this is an issue with my control, because the person I mentioned before noticed this happening with a PictureBox control. It would seem that even though the mouse button was pressed down (for the second click to open the file) while on the dialog box, the event passed through to the form and my control when the dialog closed. I have tried disabling my control while the dialog box is active, but that didn't stop it from capturing the event. I assume this is because the event is passed down after the dialog closes, so my control would be re-enabled. Does anyone know of a way to prevent that click from reaching the form and, in turn, my control? Also, can anyone confirm if this really is a bug in the FileDialog controls, or if I just have some setting configured incorrectly?

  • Pass WPF UserControl reference to another UserControl

    - by Rob Bell
    I've created two UserControls, a ValidationManager and a ValidationOutput. On a given form there is one ValidationManager and several ValidationOutput controls, one for each control that is validated. The ValidationManager is given a list of validation errors when the form is submitted, I want each ValidationOutput control to look at this list and see if there are any errors relevant to them. The code looks a bit like this: <r:ValidationManager x:Name="myValidationManager" /> ... <TextBox Name="SomeField" /> <r:ValidationOutput FieldName="SomeField" /> I need to pass a reference to the ValidationManager to each of the ValidationOutput controls. I've added a ValidationManager property to the ValidationOutput UserControl but don't know how to pass the reference to the control. I've tried the following but am just clutching at straws: <r:ValidationOutput ValidationManager="myValidationManager" /> ...and... <r:ValidationOutput ValidationManager="{Binding myValidationManager}" /> The first results in an error "Property 'ValidationManager' was not found or is not serializable for type 'ValidationOutput'" and the second "A 'Binding' cannot be set on the 'ValidationManager' property of type 'ValidationControl'. A 'Binding' can only be set on a DependencyProperty of a DependencyObject."

  • Please help with my JSP Internationalization problem

    - by wokena
    I have problem with I18N in JSP, specifically, with forms. When I enter some Czech characters (e.g., "ešcržýá...") into my page one form, into the field "fieldOne", and then show text from that field on page two, instead of Czech characters I see this as "čč". (Note, the second page gets the Czech characters with "request.getProperty("fieldOne")") Here is the source code: Page one: <%@page contentType="text/html"%> <%@page pageEncoding="UTF-8"%> <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %> <html> <head></head> <body> <form action="druha.jsp" method="post"> <input type="textarea" name="fieldOne"> <input type="submit"> </form> </body> </html> Page two: <%@page contentType="text/html" pageEncoding="UTF-8"%> <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic" %> <html> <head></head> <body> <h1>The text: </h1> <%=request.getProperty("fieldOne")%> </body> </html> Thanks for help...

  • Javascript menu that hovers over initial element

    - by TenJack
    I'm trying to build a javascript menu using prototype that when you mouseover an element, that element is hidden and a bigger element is shown in its place that closes onmouseout. This is what I have so far to give you an idea, but it doesn't work and is buggy. I'm not sure what the best general approach is: EDIT: using the prototype refactor from remi bourgarel: function socialMenuInit(){ var social_menu = $('sociable_menu'); social_menu.hide(); var share_words = $('share_words'); Event.observe(share_words,"mouseover",function(){ share_words.hide(); social_menu.show(); }); Event.observe(social_menu,"mouseout",function(){ social_menu.hide(); share_words.show(); }); } EDIT: The main problem now is that the second bigger menu(social_menu) that is shown on top of the smaller mouseover triggering element(share_words) only closes when you mouseout the smaller trigger element even though this element is hidden. EDIT: This is the html and css I am using: <div id="share_words">share</div> <div id="sociable_menu"></div> #share_words{ display: none; border: 1px solid white; position: absolute; right: 320px; top:0px; padding: 4px; background-image: url('/images/icons/group.png'); background-repeat: no-repeat; background-position:7px 6px; text-indent:26px; color: white; z-index: 15; } #sociable_menu{ border: 1px solid black; padding: 5px; position: absolute; right: 275px; top: -10px; z-index: 20; } Thanks for any help.

  • Hadoop safemode recovery - taking lot of time

The first message is thrown in task trackers log because, job tracker is not started. job tracker didn't start because of hdfs safemode recovery. The second message is thrown during the recovery process. Is there something I am doing wrong? How much time does normal hdfs safemode recovery takes? Will there be any speedup, by not starting task trackers till job tracker is started? Are there any known hadoop problems on amazon cluster? Thanks for your help. Regards Bala Mudiam

  • Polynomial operations using operator overloading

    - by Vlad
    I'm trying to use operator overloading to define the basic operations (+,-,*,/) for my polynomial class but when i run the program it crashes and my computer frozes. Update3 Ok i successfully done the first two operations(+,-). Now at multiplication, after multiplying each term of the first polynomial with each of the second i want to sort the poly list descending and then if there are more than one term with the same power to merge them in only one term, but for some reason it doesn't compile because of the sort function which doesn't work. Here's what I got: polinom operator*(const polinom& P) const { polinom Result; constIter i, j, lastItem = Result.poly.end(); Iter it1, it2; int nr_matches; for (i = poly.begin() ; i != poly.end(); i++) { for (j = P.poly.begin(); j != P.poly.end(); j++) Result.insert(i->coef * j->coef, i->pow + j->pow); } sort(Result.poly.begin(), Result.poly.end(), SortDescending()); lastItem--; while (true) { nr_matches = 0; for (it1 = Result.poly.begin(); it < lastItem; it1++) { for (it2 = it1 + 1;; it2 <= lastItem; it2++){ if (it2->pow == it1->pow) { it1->coef += it2->coef; nr_matches++; } } Result.poly.erase(it1 + 1, it1 + (nr_matches + 1)); } return Result; } Also here's SortDescending: struct SortDescending { bool operator()(const term& t1, const term& t2) { return t2.pow < t1.pow; } }; What did i do wrong? Thanks!

  • How can I test blades in MVC Turbine with Rhino Mocks?

    - by Brandon Linton
    I'm trying to set up blade unit tests in an MVC Turbine-derived site. The problem is that I can't seem to mock the IServiceLocator interface without hitting the following exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module module) at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock() at System.Reflection.Emit.TypeBuilder.CreateType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.InterfaceProxyWithTargetGenerator.GenerateCode(Type proxyTargetType, Type[] interfaces, ProxyGenerationOptions options) at Castle.DynamicProxy.DefaultProxyBuilder.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, IInterceptor[] interceptors) at Rhino.Mocks.MockRepository.MockInterface(CreateMockState mockStateFactory, Type type, Type[] extras) at Rhino.Mocks.MockRepository.CreateMockObject(Type type, CreateMockState factory, Type[] extras, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.Stub(Type type, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.<>c__DisplayClass1`1.<GenerateStub>b__0(MockRepository repo) at Rhino.Mocks.MockRepository.CreateMockInReplay<T>(Func`2 createMock) at Rhino.Mocks.MockRepository.GenerateStub<T>(Object[] argumentsForConstructor) at XXX.BladeTest.SetUp() Everything I search for regarding this error leads me to 32-bit vs. 64-bit DLL compilation issues, but MVC Turbine uses the service locator facade everywhere and we haven't had any other issues, just with using Rhino Mocks to attempt mocking it. It blows up on the second line of this NUnit set up method: IRotorContext _context; IServiceLocator _locator; [SetUp] public void SetUp() { _context = MockRepository.GenerateStub<IRotorContext>(); _locator = MockRepository.GenerateStub<IServiceLocator>(); _context.Expect(x => x.ServiceLocator).Return(_locator); } Just a quick aside; I've tried implementing a fake implementing IServiceLocator, thinking that I could just keep track of calls to the type registration methods. This won't work in our setup, because we extend the service locator's interface in such a way that if the type isn't Unity-based, the registration logic is not invoked.

  • Accurate least-squares fit algorithm needed

    - by ggkmath
    I've experimented with the two ways of implementing a least-squares fit (LSF) algorithm shown here. The first code is simply the textbook approach, as described by Wolfram's page on LSF. The second code re-arranges the equation to minimize machine errors. Both codes produce similar results for my data. I compared these results with Matlab's p=polyfit(x,y,1) function, using correlation coefficients to measure the "goodness" of fit and compare each of the 3 routines. I observed that while all 3 methods produced good results, at least for my data, Matlab's routine had the best fit (the other 2 routines had similar results to each other). Matlab's p=polyfit(x,y,1) function uses a Vandermonde matrix, V (n x 2 matrix) and QR factorization to solve the least-squares problem. In Matlab code, it looks like: V = [x1,1; x2,1; x3,1; ... xn,1] % this line is pseudo-code [Q,R] = qr(V,0); p = R\(Q'*y); % performs same as p = V\y I'm not a mathematician, so I don't understand why it would be more accurate. Although the difference is slight, in my case I need to obtain the slope from the LSF and multiply it by a large number, so any improvement in accuracy shows up in my results. For reasons I can't get into, I cannot use Matlab's routine in my work. So, I'm wondering if anyone has a more accurate equation-based approach recommendation I could use that is an improvement over the above two approaches, in terms of rounding errors/machine accuracy/etc. Any comments appreciated! thanks in advance.

    My script dynamically creates a <ul> width left-floating <li>s inside: it's a paginator. Afterwards, the script measures width of all <li>s and summs them up. The problem is that after the nodes are injected into the document — the browser refreshed DOM and applies CSS styles which takes a while. It has a negative effect on my script: when these operations are not complete before I measure the width — my script gets a wrong value. If I perform the measure in a second — everything is ok. The thing I'm looking for is a way to detect the moment when the <ul> is fully drawn, styles applied and the width has stabilizes. Or at least a way to detect every dimensions changes. If there's a way to detect width stabilization — I would do the measuring right after it to get the correct values. P.S. Why I need this. My paginator's left-floating <li> items tend to move to the next line when the <ul> tries to become wider than the page itself. Even though most of <li>s are invisible because of parent <div>'s width restriction: div { width: 500px; overflow: hidden; } div ul { width: 100%; white-space: nowrap; } div ul li { display: block; float: left; } they still go down unless I specify the actual summed width of the <ul> with the script.

  • ubuntu: sem_timedwait not waking (C)

    - by gillez
    I have 3 processes which need to be synchronized. Process one does something then wakes process two and sleeps, which does something then wakes process three and sleeps, which does something and wakes process one and sleeps. The whole loop is timed to run around 25hz (caused by an external sync into process one before it triggers process two in my "real" application). I use sem_post to trigger (wake) each process, and sem_timedwait() to wait for the trigger. This all works successfully for several hours. However at some random time (usually after somewhere between two and four hours), one of the processes starts timing out in sem_timedwait(), even though I am sure the semaphore is being triggered with sem_post(). To prove this I even use sem_getvalue() immediately after the timeout, and the value is 1, so the timedwait should have been triggered. Please see following code: #include <stdio.h> #include <time.h> #include <string.h> #include <errno.h> #include <semaphore.h> sem_t trigger_sem1, trigger_sem2, trigger_sem3; // The main thread process. Called three times with a different num arg - 1, 2 or 3. void *thread(void *arg) { int num = (int) arg; sem_t *wait, *trigger; int val, retval; struct timespec ts; struct timeval tv; switch (num) { case 1: wait = &trigger_sem1; trigger = &trigger_sem2; break; case 2: wait = &trigger_sem2; trigger = &trigger_sem3; break; case 3: wait = &trigger_sem3; trigger = &trigger_sem1; break; } while (1) { // The first thread delays by 40ms to time the whole loop. // This is an external sync in the real app. if (num == 1) usleep(40000); // print sem value before we wait. If this is 1, sem_timedwait() will // return immediately, otherwise it will block until sem_post() is called on this sem. sem_getvalue(wait, &val); printf("sem%d wait sync sem%d. val before %d\n", num, num, val); // get current time and add half a second for timeout. gettimeofday(&tv, NULL); ts.tv_sec = tv.tv_sec; ts.tv_nsec = (tv.tv_usec + 500000); // add half a second if (ts.tv_nsec > 1000000) { ts.tv_sec++; ts.tv_nsec -= 1000000; } ts.tv_nsec *= 1000; /* convert to nanosecs */ retval = sem_timedwait(wait, &ts); if (retval == -1) { // timed out. Print value of sem now. This should be 0, otherwise sem_timedwait // would have woken before timeout (unless the sem_post happened between the // timeout and this call to sem_getvalue). sem_getvalue(wait, &val); printf("!!!!!! sem%d sem_timedwait failed: %s, val now %d\n", num, strerror(errno), val); } else printf("sem%d wakeup.\n", num); // get value of semaphore to trigger. If it's 1, don't post as it has already been // triggered and sem_timedwait on this sem *should* not block. sem_getvalue(trigger, &val); if (val <= 0) { printf("sem%d send sync sem%d. val before %d\n", num, (num == 3 ? 1 : num+1), val); sem_post(trigger); } else printf("!! sem%d not sending sync, val %d\n", num, val); } } int main(int argc, char *argv[]) { pthread_t t1, t2, t3; // create semaphores. val of sem1 is 1 to trigger straight away and start the whole ball rolling. if (sem_init(&trigger_sem1, 0, 1) == -1) perror("Error creating trigger_listman semaphore"); if (sem_init(&trigger_sem2, 0, 0) == -1) perror("Error creating trigger_comms semaphore"); if (sem_init(&trigger_sem3, 0, 0) == -1) perror("Error creating trigger_vws semaphore"); pthread_create(&t1, NULL, thread, (void *) 1); pthread_create(&t2, NULL, thread, (void *) 2); pthread_create(&t3, NULL, thread, (void *) 3); pthread_join(t1, NULL); pthread_join(t2, NULL); pthread_join(t3, NULL); } The following output is printed when the program is running correctly (at the start and for a random but long time after). The value of sem1 is always 1 before thread1 waits as it sleeps for 40ms, by which time sem3 has triggered it, so it wakes straight away. The other two threads wait until the semaphore is received from the previous thread. [...] sem1 wait sync sem1. val before 1 sem1 wakeup. sem1 send sync sem2. val before 0 sem2 wakeup. sem2 send sync sem3. val before 0 sem2 wait sync sem2. val before 0 sem3 wakeup. sem3 send sync sem1. val before 0 sem3 wait sync sem3. val before 0 sem1 wait sync sem1. val before 1 sem1 wakeup. sem1 send sync sem2. val before 0 [...] However, after a few hours, one of the threads begins to timeout. I can see from the output that the semaphore is being triggered, and when I print the value after the timeout is is 1. So sem_timedwait should have woken up well before the timeout. I would never expect the value of the semaphore to be 1 after the timeout, save for the very rare occasion (almost certainly never but it's possible) when the trigger happens after the timeout but before I call sem_getvalue. Also, once it begins to fail, every sem_timedwait() on that semaphore also fails in the same way. See the following output, which I've line-numbered: 01 sem3 wait sync sem3. val before 0 02 sem1 wakeup. 03 sem1 send sync sem2. val before 0 04 sem2 wakeup. 05 sem2 send sync sem3. val before 0 06 sem2 wait sync sem2. val before 0 07 sem1 wait sync sem1. val before 0 08 !!!!!! sem3 sem_timedwait failed: Connection timed out, val now 1 09 sem3 send sync sem1. val before 0 10 sem3 wait sync sem3. val before 1 11 sem3 wakeup. 12 !! sem3 not sending sync, val 1 13 sem3 wait sync sem3. val before 0 14 sem1 wakeup. [...] On line 1, thread 3 (which I have confusingly called sem1 in the printf) waits for sem3 to be triggered. On line 5, sem2 calls sem_post for sem3. However, line 8 shows sem3 timing out, but the value of the semaphore is 1. thread3 then triggers sem1 and waits again (10). However, because the value is already 1, it wakes straight away. It doesn't send sem1 again as this has all happened before control is given to thread1, however it then waits again (val is now 0) and sem1 wakes up. This now repeats for ever, sem3 always timing out and showing that the value is 1. So, my question is why does sem3 timeout, even though the semaphore has been triggered and the value is clearly 1? I would never expect to see line 08 in the output. If it times out (because, say thread 2 has crashed or is taking too long), the value should be 0. And why does it work fine for 3 or 4 hours first before getting into this state? This is using Ubuntu 9.4 with kernel 2.6.28. The same procedure has been working properly on Redhat and Fedora. But I'm now trying to port to ubuntu! Thanks for any advice, Giles

  • JSF ui:repeat and f:ajax giving wrong value for h:inputText after rerender.

    - by Andrew
    I have a list of questions and I can display them ok using a ui:repeat, but after clicking the Edit button the rerendered inputText is given the wrong question.id. For some reason, if you click Edit on the first item, the inputText value assigned is that of the second item in the list, even though other outputs (other than the h:inputText element) are correct. <h:form id="questionnaireForm"> <ui:repeat value="#{ProjectManager.currentProject.preQuestions}" var="question" varStatus="current" id="preQuestionsRepeat"> <div> <ui:fragment rendered="#{!question.editing}"> <f:ajax render="@form"> <p>#{question.id} #{question.questionText}</p> <h:inputText value="#{question.id}"/> <h:commandLink styleClass="link" action="#{question.setEditing}" value="Edit"> </h:commandLink> </f:ajax> </ui:fragment> </div> <div> <ui:fragment rendered="#{question.editing}"> <f:ajax render="@form"> <p>#{question.id} #{question.questionText}</p> <h:inputText value="#{question.id}"/> </f:ajax> </ui:fragment> </div> </ui:repeat> </h:form> Obviously I don't really want to edit the id. I just want the correct question.something to show up in my inputText :-) Perhaps I'm not using correctly? It seems fine according to my reading so far. Many thanks for your assistance.

  • Blackberry stopwatch implementation

    - by Michaela
    I'm trying to write a blackberry app that is basically a stopwatch, and displays lap times. First, I'm not sure I'm implementing the stopwatch functionality in the most optimal way. I have a LabelField (_myLabel) that displays the 'clock' - starting at 00:00. Then you hit the start button and every second the _myLabel field gets updated with how many seconds have past since the last update (should only ever increment by 1, but sometimes there is a delay and it will skip a number). I just can't think of a different way to do it - and I am new to GUI development and threads so I guess that's why. EDIT: Here is what calls the stopwatch: _timer = new Timer(); _timer.schedule(new MyTimerTask(), 250, 250); And here is the TimerTask: class MyTimerTask extends TimerTask { long currentTime; long startTime = System.currentTimeMillis(); public void run() { synchronized (Application.getEventLock()) { currentTime = System.currentTimeMillis(); long diff = currentTime - startTime; long min = diff / 60000; long sec = (diff % 60000) / 1000; String minStr = new Long(min).toString(); String secStr = new Long(sec).toString(); if (min < 10) minStr = "0" + minStr; if (sec < 10) secStr = "0" + secStr; _myLabel.setText(minStr + ":" + secStr); timerDisplay.deleteAll(); timerDisplay.add(_timerLabel); } } } Anyway when you stop the stopwatch it updates a historical table of lap time data. When this list gets long, the timer starts to degrade. If you try to scroll, then it gets really bad. Is there a better way to implement my stopwatch?

  • Boost in Visual Studio 2010, IntelliSense error

    - by Peretz
    Hello, I would like to see if you could orient me. It happens that I compiled and referenced the boost libraries in order to use them with Visual Studio 2010. When building my test project I get these two IntelliSense errors 1 IntelliSense: #error directive: "Macro BOOST_LIB_NAME not set (internal error)" c:\boost_1_43_0\boost\config\auto_link.hpp 2 IntelliSense: #error directive: "some required macros where not defined (internal logic error)." c:\boost_1_43_0\boost\config\auto_link.hpp Checking the auto_link.hpp header file the first error is in this line #ifndef BOOST_LIB_NAME # error "Macro BOOST_LIB_NAME not set (internal error)" #endif Tracing the definition of BOOST_LIB_NAME, it seems that is defined in config.hpp by boost_regex, which code I am including below #if !defined(BOOST_REGEX_NO_LIB) && !defined(BOOST_REGEX_SOURCE) && !defined(BOOST_ALL_NO_LIB) && defined(__cplusplus) # define BOOST_LIB_NAME boost_regex # if defined(BOOST_REGEX_DYN_LINK) || defined(BOOST_ALL_DYN_LINK) # define BOOST_DYN_LINK ... more code and strangely when I point to BOOST_LIB_NAME it defines BOOST_LIB_NAME and the IntelliSense errors disappear. My program builds and executes fine using the Boost:Regex library -- with or without the Intellisense errors; however, I do not understand why these IntelliSense errors appear in the first place, and second why pointing the macro in the config.hpp defines BOOST_LIB_NAME. Any guidance will be greatly appreciated. Thanks, Jaime
