  • Simulink: type consistency errors

    - by stanigator
    Using this Simulink model file as a reference, I'm trying to figure out the two following errors: I have no idea what has gone wrong with the data type consistency/conversion problems. Do you know what the error messages mean exactly in the context of a model? It would be great to get an interpretation of the problem to solve it. Thanks in advance.

  • Disposables, Using & Try/Catch Blocks

    - by Aren B
    Having a mental block today, need a hand verifying my logic isn't fubar'ed. Traditionally I would do file i/o similar to this: FileStream fs = null; // So it's visible in the finally block try { fs = File.Open("Foo.txt", FileMode.Open); /// Do Stuff } catch(IOException) { /// Handle Stuff } finally { if (fs != null) fs.Close(); } However, this isn't very elegant. Ideally I'd like to use the using block to dispose of the filestream when I'm done, however I am unsure about the synergy between using and try/catch. This is how i'd like to implement the above: try { using(FileStream fs = File.Open("Foo.txt", FileMode.Open)) { /// Do Stuff } } catch(Exception) { /// Handle Stuff } However, I'm worried that a premature exit (via thrown exception) from within the using block may not allow the using block to complete execution and clean up it's object. Am I just paranoid, or will this actually work the way I intend it to?

  • How can I listen to multiple Serial Ports asynchronously in C#

    - by Kamiel Wanrooij
    I have an application that listens to a piece of hardware on a USB to Serial converter. My application should monitor more than one serial port at the same time. I loop the serial ports I need to listen to, and create a thread for each port. In the thread I have my data handing routine. When I assign one port, it runs flawlessly. When I listen to the other one, it also works. When I open both ports however, the second port always throws an UnauthorizedAccessException when calling serialPort.Open(). It does not matter in what order I open the ports, the second one always fails. I listen to the ports using serialPort.ReadLine() in a while loop. Can .NET open more than one port at the same time? Can I listen to both? Or should I use another (thread safe?) way to access my serial port events?

  • Saving new indicies, triangles and normals after WPF 3D transform

    - by sklitzz
    Hi, I have a 3D model which is lying flat currently, I wish for it to be rotated 90 degrees around the X axis. I have no problem doing this with the transforms. But to my knowledge all the transforms are a bunch of matrices multiplied. I would like to have the transform really alter all the coordinates of the indicies of the model. Is there a way to "save changes" after I apply a transform?

  • Django: CharField with fixed length, how?

    - by Giovanni Di Milia
    Hi everybody, I wold like to have in my model a CharField with fixed length. In other words I want that only a specified length is valid. I tried to do something like volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me an error (it seems that I can use both max_length and min_length at the same time). Is there another quick way? Thanks EDIT: Following the suggestions of some people I will be a bit more specific: My model is this: class Volume(models.Model): vid = models.AutoField(primary_key=True) jid = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal") volumenumber = models.CharField('Volume Number') date_publication = models.CharField('Date of Publication', max_length=6, blank=True) class Meta: db_table = u'volume' verbose_name = "Volume" ordering = ['jid', 'volumenumber'] unique_together = ('jid', 'volumenumber') def __unicode__(self): return (str(self.jid) + ' - ' + str(self.volumenumber)) What I want is that the volumenumber must be exactly 4 characters. I.E. if someone insert '4b' django gives an error because it expects a string of 4 characters. So I tried with volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me this error: Validating models... Unhandled exception in thread started by <function inner_run at 0x70feb0> Traceback (most recent call last): File "/Library/Python/2.5/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run self.validate(display_num_errors=True) File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/Library/Python/2.5/site-packages/django/core/management/validation.py", line 28, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 131, in get_app_errors self._populate() File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 58, in _populate self.load_app(app_name, True) File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 74, in load_app models = import_module('.models', app_name) File "/Library/Python/2.5/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 120, in <module> class Volume(models.Model): File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 123, in Volume volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) TypeError: __init__() got an unexpected keyword argument 'min_length' That obviously doesn't appear if I use only "max_length" OR "min_length". I read the documentation on the django web site and it seems that I'm right (I cannot use both together) so I'm asking if there is another way to solve the problem. Thanks again

  • Capistrano, Mercurial and branches

    - by J. Pablo Fernández
    It is my understanding that although Mercurial has support from branches, the community generally clone repos instead of creating branches. Similar to the Darcs model, unlike the Git model. I'm deploying a Ruby on Rails app with Capistrano and there I'd like to separate the production from the development branch. Should I point Capistrano to a different repo or should I use branches?

Does anyone know what I am doing wrong? Solution As pointed in the answers, the error says that the InvoiceItem class was missing a primaryKey. I tried with: @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Long id; But I was getting javax.jdo.JDOFatalUserException: Error in meta-data for InvoiceItem.id: Cannot have a java.lang.Long primary key and be a child object (owning field is Invoice.items). In persist list of objets, @aldrin pointed that For child classes the primary key has to be a com.google.appengine.api.datastore.Key value (or encoded as a string) see So, I tried with Key. It worked. @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) private Key id;

  • Are there free realtime financial data feeds since the demise of OpenQuant?

    - by Mel Cooper
    Now that the oligopole of market data providers successfully killed OpenQuant, does any alternative to proprietary and expensive subscriptions for realtime market data subsist? Ideally I would like to be able to monitor tick by tick securities from the NYSE, NASDAQ and AMEX (about 6000 symbols). Most vendors put a limit of 500 symbols watchable at the same time, this is unacceptable to me, even if one can imagine a rotation among the 500 symbols ie. making windows of 5 sec. of effective observation out of each minute for every symbol. Currently I'm doing this by a Java thread pool calling Google Finance, but this is unsatisfactory for several reasons, one being that Google doesn't return the volume traded. Any hint much appreciated, Cheers

  • 2 questions. IDO mode not caching properly / forcing buffers to named windows.

    - by user112043
    1 My ido mode does not properly cache filenames / folders. It will list files inside a folder, but from a while ago without any of the newer files showing. Any suggestions ? 2 In jde, when I have multiple windows open, compiling on one window will create a corresponding "* name of the class *" that will open on the next window in order. This is fine if I only have one window open but can I get some help writing a function that I could use to : Name a window Force all buffers of JDE compile server to only ever open in that window if it exists Force all run windows from jde in the form of * name of the class * to open in the same window if it exists. Jde automatically names the buffer " * name of the class * ", I will probably dig around the codes to find an easy fix for that... so if the code could just force all windows using a regexp containing * jde run - filename * or something along the lines would also work. Thanks for your help, first post here as well. I really would like just some ideas on what may be going wrong with 1, 2 if anyone is feeling kind.

  • How do I rename an R object?

    I'm using the quantmod package to import financial series data from Yahoo. library(quantmod) getSymbols("^GSPC") [1] "GSPC" I'd like to change the name of object "GSPC" to "SPX". I've tried the rename function in the reshape package, but it only changes the variable names. The "GSPC" object has vectors GSPC.Open, GSPC.High, etc. I'd like my renaming of "GSPC" to "SPX" to also change GSPC.Open to SPX.Open and so on.

First, when I flop the comment on these 2 lines below: # myform = GradeForm(data=request.POST, instance=mygrade) myform = GradeROForm(data=request.POST, instance=mygrade) it works like I expect, except of course that the student field is changeable. When the comments are the shown way, the "studentId" field is displayed as a number (not the name, problem 1) and when I hit submit I get an error saying that studentId needs to be a Student instance. I'm at a loss as to how to fix this. I'm not wedded to Alex Gaynor's code. ANY code will work. I'm relatively new to both Python and Django, so the hints I've seen on websites that say "making a read-only field is easy" are still beyond me. // models.py class Student(models.Model): name = models.CharField(max_length=50) parent = models.CharField(max_length=50) def __unicode__(self): return self.name class Grade(models.Model): studentId = models.ForeignKey(Student) finalGrade = models.CharField(max_length=3) # testbed.grades.readonly is alex gaynor's code from testbed.grades.readonly import ReadOnlyField class GradeROForm(ModelForm): studentId = ReadOnlyField() class Meta: model=Grade class GradeForm(ModelForm): class Meta: model=Grade // views.py def modifyGrade(request,student): student = Student.objects.get(name=student) mygrade = Grade.objects.get(studentId=student) if request.method == "POST": # myform = GradeForm(data=request.POST, instance=mygrade) myform = GradeROForm(data=request.POST, instance=mygrade) if myform.is_valid(): grade = myform.save() info = "successfully updated %s" % grade.studentId else: # myform=GradeForm(instance=mygrade) myform=GradeROForm(instance=mygrade) return render_to_response('grades/modifyGrade.html',locals()) // template <p>{{ info }}</p> <form method="POST" action=""> <table> {{ myform.as_table }} </table> <input type="submit" value="Submit"> </form> // Alex Gaynor's code from django import forms from django.utils.html import escape from django.utils.safestring import mark_safe from django.forms.util import flatatt class ReadOnlyWidget(forms.Widget): def render(self, name, value, attrs): final_attrs = self.build_attrs(attrs, name=name) if hasattr(self, 'initial'): value = self.initial return mark_safe("<span %s>%s</span>" % (flatatt(final_attrs), escape(value) or '')) def _has_changed(self, initial, data): return False class ReadOnlyField(forms.FileField): widget = ReadOnlyWidget def __init__(self, widget=None, label=None, initial=None, help_text=None): forms.Field.__init__(self, label=label, initial=initial, help_text=help_text, widget=widget) def clean(self, value, initial): self.widget.initial = initial return initial

  • ICalendar not readable by google calendar.

    - by Sagar
    Operating system : WinXP Program and version you use to access Google Calendar (FF3.5): I'm developing a script (based on an existing vCal ASP.NET class I found online) to generate an .ics file. This file works perfectly when importing to Outlook 2003. When I try to import to Google Calendar, I get the following error: Failed to import events: Unable to process your iCal/CSV file.. I don't know too much about the vCal format or syntax, but everything looks fine to me.

  • Does my fat-client application belong in the MVC pattern?

    - by boatingcow
    The web-based application I’m currently working on is growing arms and legs! It’s basically an administration system which helps users to keep track of bookings, user accounts, invoicing etc. It can also be accessed via a couple of different websites using a fairly crude API. The fat-client design loosely follows the MVC pattern (or perhaps MVP) with a php/MySQL backend, Front Controller, several dissimilar Page Controllers, a liberal smattering of object-oriented and procedural Models, a confusing bunch of Views and templates, some JavaScripts, CSS files and Flash objects. The programmer in me is a big fan of the principle of “Separation of Concerns” and on that note, I’m currently trying to figure out the best way to separate and combine the various concerns as the project grows and more people contribute to it. The problem we’re facing is that although JavaScript (or Flash with ActionScript) is normally written with the template, hence part of the View and decoupled from the Controller and Model, we find that it actually encompasses the entire MVC pattern... Swap an image with an onmouseover event - that’s Behaviour. Render a datagrid - we’re manipulating the View. Send the result of reordering a list via AJAX - now we’re in Control. Check a form field to see if an email address is in a valid format - we’re consulting the Model. Is it wise to let the database people write up the validation Model with jQuery? Can the php programmers write the necessary Control structures in JavaScript? Can the web designers really write a functional AJAX form for their View? Should there be a JavaScript overlord for every project? If the MVC pattern could be applied to the people instead of the code, we would end up with this: Model - the database boffins - “SELECT * FROM mind WHERE interested IS NULL” Control - pesky programmers - “class Something extends NothingAbstractClass{…}” View - traditionally the domain of the graphic/web designer - “” …and a new layer: Behaviour - interaction and feedback designer - “CSS3 is the new black…” So, we’re refactoring and I’d like to stick to best practice design, but I’m not sure how to proceed. I don’t want to reinvent the wheel, so would anyone have any hints or tips as to what pattern I should be looking at or any code samples from someone who’s already done the dirty work? As the programmer guy, how can I rewrite the app for backend and front end whilst keeping the two separate? And before you ask, yes I’ve looked at Zend, CodeIgnitor, Symfony, etc., and no, they don’t seem to cross the boundary between server logic and client logic!

  • Selenium RC test - IE gives 403 error on Tomcat app, Tomcat root OK

    - by Ed Daniel
    I'm new to Selenium RC, having previously used Selenium IDE and only run tests in Firefox. I'm trying to get a basic test to run using Selenium RC through Eclipse; my test works OK in Firefox, and in Safari now that I've killed the pop-up blocker, but IE8 is causing a SeleniumException to be thrown, containing an "XHR ERROR" with a 403 response: com.thoughtworks.selenium.SeleniumException: XHR ERROR: URL = http://localhost:8080/pims Response_Code = 403 Error_Message = Forbidden at com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:91) at com.thoughtworks.selenium.DefaultSelenium.open(DefaultSelenium.java:335) at org.pimslims.seleniumtest.FirstTest.testNew(FirstTest.java:32) ... I can do a similar test on http:/ /localhost:8080 (space between the slashes here because SO thinks I'm spamming) and it's fine - I can make IE open that Tomcat default page and click a link. It's only if I try to open my application at http:/ /localhost:8080/pims that I see this error - and only in IE. I can open that URL in IE by typing it into the address bar. I was convinced that there's some setting in IE that's causing this, but I've tried everything I can think of. http:/ /localhost:8080 is in my Trusted Sites, and I've turned the security for that zone down to the minimum, allowed anything that looks related to popups, etc. If I try adding http:/ /localhost:8080/pims/ to Trusted Sites, IE says it's already there. I've also messed around with proxy settings, to no avail, but may have missed something obvious. I've tried starting the test with *iexplore, *iehta, and *iexploreproxy - all behave the same. Is there something I've missed? For reference, here is my test case - this works as is, in Firefox, opening the PIMS application's index page and clicking a link: public class FirstTest extends SeleneseTestCase { @Override public void setUp() throws Exception { this.setUp("http://localhost:8080/", "*firefox"); } public void testNew() throws Exception { final Selenium s = this.selenium; s.open("/pims"); s.click("logInOutLink"); s.waitForPageToLoad("30000"); } } Any help is greatly appreciated!

  • PyQt QDataWidgetMapper submit doesn't work

    - by DSblizzard
    Here is the parts of code (Mw - main window, Ed - edit dialog, Tv - table view): Mw.mapper = QDataWidgetMapper(Mw) Mw.mapper.setSubmitPolicy(QDataWidgetMapper.ManualSubmit) Mw.mapper.setItemDelegate( QSqlRelationalDelegate(Mw.mapper) ) Mw.mapper.setModel(Table.Model) # Id - first invisible key column Mw.mapper.addMapping(Ed.leName, Name) # Name == 1 Mw.mapper.addMapping(Ed.leSize, Size) # Size == 2 Mw.mapper.toFirst() Row = Tv.currentIndex().row() Mw.mapper.setCurrentIndex(Row) Ed.setModal(1) Ed.show() Res = Mw.mapper.submit() # False Table.Model.submitAll() SQL UPDATE statement works in this case. Why problem with mapper?

  • Looking for Antlr Grammar syntaxt highlight in VS2010

    - by David Mårtensson
    I am looking for some way to edit antlr grammar files directly within VS2010 with syntax highlight. I have used antlrworks a lot but it has the drawback that I have to start antlrworks separately and then browse to the file I want to edit, do the changed and save. For minor fixes I do not need all the tools in Antlrworks but I still would like the syntax highlight. But I have not been able to get VS2010 to open antlrworks with the right file and I have found no other way to get syntax highlight directly within VS2010 editor, it just opens as plain text. I can get visual studio to open antlrworks but it will open with only the last set of files it had open, not the one I clicked on. So my question(s) are: Is there a way to get antlrworks to open with the right file when I double click in it in visual studio project explorer? Is there any other way to get correct syntax highlight for antlr grammar files within visual studio (or with another editor, preferably not one that costs money, but if there are no free ones a commercial one might be an option).

  • Accessing an object's fields without an active session

    - by Dave
    I'm using Hibernate 4.0.1.Final. Is it possible to access an object's fields if that object has been loaded via the org.hibernate.Session.load(Class clazz, Serializable id) method and there is no active session? I use this code to access an object by id … protected Object find(Class clazz, Serializable id) { Object obj = null; try { startOperation(); obj = session.load(clazz, id); tx.commit(); } catch (HibernateException e) { handleException(e); } finally { session.close(); } return obj; } but if I have that object without an active session, like with this code … final Organization foundOrg = orgDao.findById(org.getOrganizationId()); System.out.println(foundOrg.getName()); I get this error on the "System.out" line … org.hibernate.LazyInitializationException: could not initialize proxy - no Session at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:149) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:195) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:185) at org.myco.myproject.orgsclient.model.Organization_$$_javassist_0.getName(Organization_$$_javassist_0.java) at org.myco.myproject.orgsclient.dao.OrganizationDAOTest.testInsertSchool(OrganizationDAOTest.java:43) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:44) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:15) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:41) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:20) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:28) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:76) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:193) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:52) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:191) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:42) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:184) at org.junit.runners.ParentRunner.run(ParentRunner.java:236) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:50) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

  • IE8 window.opener problems

    - by fire
    Having problems with IE8... I have a button that onclick fires the showImageBrowser() function. function showImageBrowser(params) { var open = window.open('http://localhost/admin/browse?'+params,'newwin','toolbar=0,location=0,directories=0,status=1,menubar=0,scrollbars=1,resizable=1,width=950,height=500'); if (!open) { alert('Could not open the image browser, please disable your popup blocker.'); } } Now in the image browser when you click on an image it calls this function: function selectFile(url, el) { window.opener.replaceImage('Test_Image', url); window.close(); } Which is calling the replaceImage() function in the parent window, as expeted. This is the code: function replaceImage(el, url) { $('#'+el).html('<a href="'+url+'" target="_blank" class="image">'+basename(url)+'</a>'); $("input[name='"+el+"']").val(url); } Now if you click on the original showImageBrowser() button for the second time, IE will bring up the window but this time it freezes for a few seconds and then you get the alert "Could not open the image browser, please disable your popup blocker." This works fine in Firefox (obviously) but not in IE. I haven't even tried it in IE7/6 because if it doesn't work in 8 then I know I'm going to have problems. Any advice?
