  • C# Attribute XmlIgnore and XamlWriter class - XmlIgnore not working

    - by Horst Walter
    I have a class, containing a property Brush MyBrush marked as [XmlIgnore]. Nevertheless it is serialized in the stream causing trouble when trying to read via XamlReader. I did some tests, e.g. when changing the visibility (to internal) of the Property it is gone in the stream. Unfortunately I cannot do this in my particular scenario. Did anybody have the same issue and? Do you see any way to work around this? Remark: C# 4.0 as far I can tell This is a method from my Unit Test where I do test the XamlSerialization: // buffer to a StringBuilder StringBuilder sb = new StringBuilder(); XmlWriter writer = XmlWriter.Create(sb, settings); XamlDesignerSerializationManager manager = new XamlDesignerSerializationManager(writer) {XamlWriterMode = XamlWriterMode.Expression}; XamlWriter.Save(testObject, manager); xml = sb.ToString(); Assert.IsTrue(!String.IsNullOrEmpty(xml) && !String.IsNullOrEmpty(xml), "Xaml Serialization failed for " + testObject.GetType() + " no xml string available"); xml = sb.ToString(); MemoryStream ms = xml.StringToStream(); object root = XamlReader.Load(ms); Assert.IsTrue(root != null, "After reading from MemoryStream no result for Xaml Serialization"); In one of my classes I use the Property Brush. In the above code this Unit Tests fails because of a Brush object not serializable is the value. When I remove the Setter (as below, the Unit Test passes. Using the XmlWriter (basically same test as above) it works. In the StringBuffer sb I can see that Property Brush is serialized when the Setter is there and not when removed (most likely another check ignoring the Property because of no setter). Other Properties with [XmlIgnore] are ignored as intended. [XmlIgnore] public Brush MyBrush { get { ..... } // removed because of problem with Serialization // set { ... } }

  • Python script shows different pythonpath

    - by Bird Jaguar IV
    Attempting to run runsnake gives ImportError: No module named wx Opening an ipython or python session seems to work fine: >>> import wx >>> import sys >>> print [p for p in sys.path if 'wx' in p] ['/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages', '/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages/wx-2.9.4-osx_cocoa', '/usr/local/lib/wxPython-2.9.4.0/lib/python2.7/site-packages/wx-2.9.1-osx_cocoa/tools'] as does putting that code in a script and calling python script.py. But putting that code at the beginning of runsnake.py prints an empty list (printing the whole sys.path prints a path quite different from my $PYTHONPATH). Why would it be different, and how to I get it to recognize wxPython?

  • Why am I getting a ParseException when using SimpleDateFormat to format a date and then parse it?

    - by Greg
    I have been debugging some existing code for which unit tests are failing on my system, but not on colleagues' systems. The root cause is that SimpleDateFormat is throwing ParseExceptions when parsing dates that should be parseable. I created a unit test that demonstrates the code that is failing on my system: import java.text.DateFormat; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.Date; import java.util.TimeZone; import junit.framework.TestCase; public class FormatsTest extends TestCase { public void testParse() throws ParseException { DateFormat formatter = new SimpleDateFormat("yyyyMMddHHmmss.SSS Z"); formatter.setTimeZone(TimeZone.getDefault()); formatter.setLenient(false); formatter.parse(formatter.format(new Date())); } } This test throws a ParseException on my system, but runs successfully on other systems. java.text.ParseException: Unparseable date: "20100603100243.118 -0600" at java.text.DateFormat.parse(DateFormat.java:352) at FormatsTest.testParse(FormatsTest.java:16) I have found that I can setLenient(true) and the test will succeed. The setLenient(false) is what is used in the production code that this test mimics, so I don't want to change it.

  • Is it right that Strophe.addHandler reads only first node from response?

    - by markcial
    I'm starting to learn strophe library usage and when i use addHandler to parse response it seems to read only first node of xml response so when i receive a xml like that : <body xmlns='http://jabber.org/protocol/httpbind'> <presence xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='avaliable' id='5593:sendIQ'> <status/> </presence> <presence xmlns='jabber:client' from='test@localhost' to='test2@localhost' xml:lang='en'> <status /> </presence> <iq xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='result'> <query xmlns='jabber:iq:roster'> <item subscription='both' name='test' jid='test@localhost'> <group>test group</group> </item> </query> </iq> </body> With the handler testHandler used like that : connection.addHandler(testHandler,null,"presence"); function testHandler(stanza){ console.log(stanza); } It only logs : <presence xmlns='jabber:client' from='test2@localhost' to='test2@localhost' type='avaliable' id='5593:sendIQ'> <status/> </presence> What i am missing? is it a right behaviour? Should i add more handlers to get the other stanzas? Thanks for advance

  • SQL Server Collation / ADO.NET DataTable.Locale with different languages

    - by Turro
    Hi all, we have WinForms app which stores data in SQL Server (2000, we are working on porting it in 2008) through ADO.NET (1.1, working on porting to 4.0). Everything works fine if I read data previsouly written in Western-European locale (E.g.: "test", "test ù"), but now we have to be able to mix Western and non-Western alphabets as well (E.g.: "test - ???" - these are just random arabic chars). On the SQL Server side, database has been set with the Latin1_General collation, the field is a nvarchar(80). If I run a SQL SELECT statement (E.g.: "SELECT * FROM MyTable WHERE field = 'test - ???'", don't mind about the "*" or the actual names) from Query Analyzer, I get no results; the same happens if I pass the Sql statement to an ADO.NET DataAdapter to fill a DataTable. My guess is that it has something to do with collation, but I don't know how to correct this: do I have to change to collation (SQL Server) to a different one? Or do I have to set the locale on the DataAdaoter/DataTable (ADO.NET)? Thanks in advance to anyone who will help

  • Loading Views dynamically

    - by Dann
    Case 1: I have created View-based sample application and tried execute below code. When I press on "Job List" button it should load another view having "Back Btn" on it. In test function, if I use [self.navigationController pushViewController:jbc animated:YES]; nothing gets loaded, but if I use [self presentModalViewController:jbc animated:YES]; it loads another view haveing "Back Btn" on it. Case 2: I did create another Navigation Based Applicaton and used [self.navigationController pushViewController:jbc animated:YES]; it worked as I wanted. Can someone please explain why it was not working in Case 1. Does it has something to do with type of project that is selected? @interface MWViewController : UIViewController { } -(void) test; @end @interface JobViewCtrl : UIViewController { } @end @implementation MWViewController (void)viewDidLoad { UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Job List!" forState:UIControlStateNormal]; [btn addTarget:self action:@selector(test) forControlEvents:UIControlEventTouchUpInside]; [self.view addSubview:btn]; [super viewDidLoad]; } -(void) test { JobViewCtrl* jbc = [[JobViewCtrl alloc] init]; [self.navigationController pushViewController:jbc animated:YES]; //[self presentModalViewController:jbc animated:YES]; [jbc release]; } (void)dealloc { [super dealloc]; } @end @implementation JobViewCtrl -(void) loadView { self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; self.view.backgroundColor = [UIColor grayColor]; UIButton* btn = [UIButton buttonWithType:UIButtonTypeRoundedRect]; btn.frame = CGRectMake(80, 170, 150, 35); [btn setTitle:@"Back Btn!" forState:UIControlStateNormal]; [self.view addSubview:btn]; } @end

  • SQLAlchemy declarative syntax with autoload in Pylons

    - by Juliusz Gonera
    I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_init_.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get: sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table's MetaData. Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData with an engine via metadata.bind=<someengine> The problem here is that I don't know where to get the engine from (to use it in autoload_with) at the stage of importing the model (it's available in init_model()). I tried adding meta.Base.metadata.bind(engine) to environment.py but it doesn't work. Anyone has found some elegant solution?

  • Syntax error results in blank page

    - by Philipp
    I am new to wicket and trying to get some things working. One thing that annoys me a lot is that I get a blank (0 chars of text) page whenever there is a syntax error on a page. Striped down example: Test.html header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest" id="message">MSG</span> footer stuff: /body ... /html Test.java public class Test extends WebPage { public Test() { add(new Label("msgTest", "Hello, World!")); } } This will output the page as expected. Now, lets introduce an error: header stuff: doctype ... html ... head ... body ... <span wicket:id="msgTest2" id="message">MSG</span> footer stuff: /body ... /html I changed the label-id to something different then what the source-file expects. If I run this code I get the already mentioned blank page. However, for every request to a page with such a syntax error I get an error report in the log-file of around 1000+ lines. This error-report is basically just wicket-generated html of a page which describes the error. This makes me wonder why wicket isn't displaying the error-stuff instead of the blank page. I'm not very experienced with wicket but to me it somehow looks like wicket is having trouble rendering its own error-page code. It would be nice to know how one goes about finding syntax-errors with wicket. Reading through a 1000+ line error-report for a small error like a misplaced character seems a bit tedious. Thanks in advance for guiding me into the right direction :) PS: wicket-version: 1.4.9 stage: development

  • In .NET, how do I prevent, or handle, tampering with form data of disabled fields before submission?

    - by David
    Hi, If a disabled drop-down list is dynamically rendered to the page, it is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute. This code: protected override void OnLoad(EventArgs e) { var ddlTest = new DropDownList() {ID="ddlTest", Enabled = false}; ddlTest.Items.AddRange(new [] { new ListItem("Please select", ""), new ListItem("test 1", "1"), new ListItem("test 2", "2") }); Controls.Add(ddlTest); } results in this HTML being rendered: <select disabled="disabled" id="Properties_ddlTest" name="Properties$ddlTest"> <option value="" selected="selected">Please select</option> <option value="1">test 1</option> <option value="2">test 2</option> </select> The problem occurs when I use Firebug to remove the "disabled" attribute, and to change the selected option. On submission of the form, and re-creation of the field, the newly generated control has the correct value by the end of OnLoad, but by OnPreRender, it has assumed the identity of the submitted control and has been given the submitted form value. .NET seems to have no way of detecting the fact that the field was originally created in a disabled state and that the submitted value was faked. This is understandable, as there could be legitimate, client-side functionality that would allow the disabled attribute to be removed. Is there some way, other than a brute force approach, of detecting that this field's value should not have been changed? I see the brute force approach as being something crap, like saving the correct value somewhere while still in OnLoad, and restoring the value in the OnPreRender. As some fields have dependencies on others, that would be unacceptable to me.

  • Usage of Assert.Inconclusive

    - by Johannes Rudolph
    Hi, Im wondering how someone should use Assert.Inconclusive(). I'm using it if my Unit test would be about to fail for a reason other than what it is for. E.g. i have a method on a class that calculates the sum of an array of ints. On the same class there is also a method to calculate the average of the element. It is implemented by calling sum and dividing it by the length of the array. Writing a Unit test for Sum() is simple. However, when i write a test for Average() and Sum() fails, Average() is likely to fail also. The failure of Average is not explicit about the reason it failed, it failed for a reason other than what it should test for. That's why i would check if Sum() returns the correct result, otherwise i Assert.Inconclusive(). Is this to be considered good practice? What is Assert.Inconclusive intended for? Or should i rather solve the previous example by means of an Isolation Framework?

  • ObjC internals. Why my duck typing attempt failed?

    - by Piotr Czapla
    I've tried to use id to create duck typing in objective-c. The concept looks fine in theory but failed in practice. I was unable to use any parameters in my methods. The methods were called but parameters were wrong. I was getting BAD_ACESS for objects and random values for primitives. I've attached a simple example below. The question: Does any one knows why the methods parameters are wrong? What is happening under the hood of the objective-c? Note: I'm interest in the details. I know how to make the example below work. An example: I've created a simple class Test that is passed to an other class using property id test. @implementation Test - (void) aSampleMethodWithFloat:(float) f andInt: (int) i { NSLog(@"Parameters: %f, %i\n", f, i); } @end Then in the class the following loop is executed: for (float f=0.0f; f < 100.0f ; f += 0.3f) { [self.test aSampleMethodWithOneFloatParameter: f]; // warning: no method found. } Here is the output that I'm getting. As you can see the method was called but the parameters were wrong. Parameters: 0.000000, 0 Parameters: -0.000000, 1069128089 Parameters: -0.000000, 1070176665 Parameters: 2.000000, 1070805811 Parameters: -0.000000, 1071225241 Parameters: 0.000000, 1071644672 Parameters: 2.000000, 1071854387 Parameters: 36893488147419103232.000000, 1072064102 Parameters: -0.000000, 1072273817 Parameters: -36893488147419103232.000000, 1072483532

  • Python module seeing a full list as empty in another module

    - by Nick
    I'm working on a pygame project and have the main engine layed out. The problem is I hit a bug that I just can not seem to figure out. What happens is one module can't read a variable from another module. It's not that the variable can't be read, it just sees an empty list instead of what it really is. Instead of posting the entire source code I reproduced the bug in two small snippets that hopefully a skillful python-ist can interpret in his\her head. Code: main.py (This is the file that gets run) import screen screens = [] #A stack for all the game screens def current_screen(): #return a reference to the current screen return screens[-1] def play(): print'play called' current_screen().update() if __name__=='__main__': screens.append(screen.Screen()) play() screen.py import main class Screen: def __init__(self): print'screen made' def update(self): print main.screens #Should have a reference to itself in there Thanks!

  • Strange behavior with Javascript's __defineSetter__

    - by Shea Barton
    I have a large project in which I need to intercept assignments to things like element.src, element.href, element.style, etc. I figured out to do this with defineSetter, but it is behaving very strangely (using Chrome 8.0.552.231) An example: var attribs = ["href", "src", "background", "action", "onblur", "style", "onchange", "onclick", "ondblclick", "onerror", "onfocus", "onkeydown", "onkeypress", "onkeyup", "onmousedown", "onmousemove", "onmouseover", "onmouseup", "onresize", "onselect", "onunload"]; for(a = 0; a < attribs.length; a++) { var attrib_name = attribs[a]; var func = new Function("attrib_value", "this.setAttribute(\"" + attrib_name + "\", attrib_value.toUpperCase());"); HTMLElement.prototype.__defineSetter__(attrib_name, func); } What this code should do is whenever common element attribute in attribs is assigned, it uses setAttribute() to set a uppercased version of that attribute. For some very strange reason, the setter works for only ~1/3 of the assignments. For example with element.src = "test" the new src is "TEST", like it should be however with element.href = "test" the new href is "test", not uppercase then even when I try element.__lookupSetter__("href"), it returns the proper, uppercasing setter the strangest thing is different variables are intercepted properly between Chrome and Firefox help!!

  • What's the best way to access Neo4j from Django?

    - by abdel
    it seems that i found something that let me confused; i've found two Neo4j to download to python, the first one is: http://pypi.python.org/pypi/neo4j-embedded and the second one is: https://svn.neo4j.org/components/neo4j.py/trunk/ what's the difference between the two? the first one seems to be big (size), so does this mean that if i use it i'll not need the neo4j community release (milestone)? when i've installed the first one, and tried to test a django example, it seems that the directory named "model" https://svn.neo4j.org/components/neo4j.py/trunk/src/main/python/neo4j/model/ is missing? so what's the difference, and who will be better to use with Django? and what about that one? http://pypi.python.org/pypi/neo4django/

  • 'int' object is not callable

    - by Oscar Reyes
    I'm trying to define a simply Fraction class And I'm getting this error: python fraction.py Traceback (most recent call last): File "fraction.py", line 20, in <module> f.numerator(2) TypeError: 'int' object is not callable The code follows: class Fraction(object): def __init__( self, n=0, d=0 ): self.numerator = n self.denominator = d def get_numerator(self): return self.numerator def get_denominator(self): return self.denominator def numerator(self, n): self.numerator = n def denominator( self, d ): self.denominator = d def prints( self ): print "%d/%d" %(self.numerator, self.denominator) if __name__ == "__main__": f = Fraction() f.numerator(2) f.denominator(5) f.prints() I thought it was because I had numerator(self) and numerator(self, n) but now I know Python doesn't have method overloading ( function overloading ) so I renamed to get_numerator but that's not the problems. What could it be?
