  • XmlSerializer construction with same named extra types

    - by NoizWaves
    Hey, I am hitting trouble constructing an XmlSerializer where the extra types contains types with the same Name (but unique Fullname). Below is an example that illustrated my scenario. Type definitions in external assembly I cannot manipulate: public static class Wheel { public enum Status { Stopped, Spinning } } public static class Engine { public enum Status { Idle, Full } } Class I have written and have control over: public class Car { public Wheel.Status WheelStatus; public Engine.Status EngineStatus; public static string Serialize(Car car) { var xs = new XmlSerializer(typeof(Car), new[] {typeof(Wheel.Status),typeof(Engine.Status)}); var output = new StringBuilder(); using (var sw = new StringWriter(output)) xs.Serialize(sw, car); return output.ToString(); } } The XmlSerializer constructor throws a System.InvalidOperationException with Message "There was an error reflecting type 'Engine.Status'" This exception has an InnerException of type System.InvalidOperationException and with Message "Types 'Wheel.Status' and 'Engine.Status' both use the XML type name, 'Status', from namespace ''. Use XML attributes to specify a unique XML name and/or namespace for the type." Given that I am unable to alter the enum types, how can I construct an XmlSerializer that will serialize Car successfully?

  • MemoryStream instance timing help

    - by rod
    Hi All, Is it ok to instance a MemoryStream at the top of my method, do a bunch of stuff to it, and then use it? For instance: public static byte[] TestCode() { MemoryStream m = new MemoryStream(); ... ... whole bunch of stuff in between ... ... //finally using(m) { return m.ToArray(); } } Updated code public static byte[] GetSamplePDF() { using (MemoryStream m = new MemoryStream()) { Document document = new Document(); PdfWriter.GetInstance(document, m); document.Open(); PopulateTheDocument(document); document.Close(); return m.ToArray(); } } private static void PopulateTheDocument(Document document) { Table aTable = new Table(2, 2); aTable.AddCell("0.0"); aTable.AddCell("0.1"); aTable.AddCell("1.0"); aTable.AddCell("1.1"); document.Add(aTable); for (int i = 0; i < 20; i++) { document.Add(new Phrase("Hello World, Hello Sun, Hello Moon, Hello Stars, Hello Sea, Hello Land, Hello People. ")); } } My point was to try to reuse building the byte code. In other words, build up any kind of document and then send it to TestCode() method.

  • How detect length of a numpy array with only one element?

    - by mishaF
    I am reading in a file using numpy.genfromtxt which brings in columns of both strings and numeric values. One thing I need to do is detect the length of the input. This is all fine provided there are more than one value read into each array. But...if there is only one element in the resulting array, the logic fails. I can recreate an example here: import numpy as np a = np.array(2.3) len(a) returns an error saying: TypeError: len() of unsized object however, If a has 2 or more elements, len() behaves as one would expect. import numpy as np a = np.array([2.3,3.6]) len(a) returns 2 My concern here is, if I use some strange exception handling, I can't distinguish between a being empty and a having length = 1.

  • How to refresh database data only in SQL Server

    - by MaxGeek
    So I want to copy just the data from a Prod database (SQL 2005) down to my local machine (SQL 2005 & SQL 2008 Management Studio installed). The problem is I'm running into foreign key constraints that are causing the task/scripts to fail. I can get by these errors if I import certain tables first, but is there an easier way to do this all at once? I'm not a DBA so I don't have access to the database back up. I've tried the SQL Import/Export data Wizard and Publishing Wizard, but it also gets the PK error.

  • can i add textfields in the code other than in the init?

    - by themanepalli
    Im a 15 year old noob to java. I am trying to make a basic program trader that asks for the stock price, the stock name, the stock market value and the type of order. Based on the type of order, i want a new textfield to appear. do i have to add the textfield in the init first or can i do it in the action performed. I googled someother ones but they are a little too complicated for me. heres my code. import java.awt.*; import java.applet.*; // import an extra class for the ActionListener import java.awt.event.*; public class mathFair extends Applet implements ActionListener { TextField stockPrice2; TextField stockName2; TextField orderType2; TextField marketValue2; TextField buyOrder2; TextField sellOrder2; TextField limitOrder2; TextField stopLossOrder2; Label stockPrice1; Label stockName1; Label orderType1; Label marketValue1; Label buyOrder1; Label sellOrder1; Label limitOrder1; Label stopLossOrder1; Button calculate; public void init() { stockPrice1 = new Label ("Enter Stock Price:"); stockName1 = new Label ("Enter Name of Stock: "); orderType1 = new Label ("Enter Type of Order: 1 for Buy, 2 for Sell, 3 for Stop Loss, 4 for Limit"); marketValue1= new Label("Enter The Current Price Of The Market"); stopLossOrder1 = new Label ("Enter The Lowest Price The Stock Can Go"); limitOrder1 = new Label ("Enter The Highest Price The Stock Can Go"); stockPrice2 = new TextField (35); stockName2 = new TextField (35); orderType2 = new TextField (35); marketValue2= new TextField(35); calculate= new Button("Start The Simulation"); add (stockPrice1); add (stockPrice2); add (stockName1); add (stockName2); add (marketValue1); ; add(marketValue2); add (orderType1); add (orderType2); add(calculate); ; calculate.addActionListener(this); } public void actionPerformed (ActionEvent e) { String stock= stockPrice2.getText(); int stockPrice= Integer.parseInt(stock); stockPrice2.setText(stockPrice +""); String marketV= marketValue2.getText(); int marketValue= Integer.parseInt(marketV); marketValue2.setText(marketValue+""); String orderT= orderType2.getText(); int orderType= Integer.parseInt(orderT); orderType2.setText(orderType+""); if((e.getSource()==calculate)&& (orderType==1)) { buyOrder2= new TextField(35); buyOrder1 = new Label("Enter Price You Would Like To Buy At"); add(buyOrder2); add(buyOrder1); } else if((e.getSource()==calculate)&& (orderType==2)) { sellOrder2= new TextField(35); sellOrder1 = new Label("Enter Price You Would Like To Sell At"); add(sellOrder2); add(sellOrder1); } else if((e.getSource()==calculate)&& (orderType==3)) { stopLossOrder2= new TextField(35); stopLossOrder1=new Label("Enter The Lowest Price The Stock Can Go"); add(stopLossOrder2); add(stopLossOrder1); } else if((e.getSource()==calculate)&& (orderType==4)) { limitOrder2=new TextField(35); limitOrder1= new Label("Enter the Highest Price The Stock Can Go"); add(limitOrder2); add(limitOrder1);; } } }

  • @property, ok in this situation?

    - by fuzzygoat
    I am still finding my feet with objective-c and was wondering if its acceptable to use @property on the two objects below. #import <UIKit/UIKit.h> #import <MapKit/MapKit.h> @interface MapViewController : UIViewController <MKMapViewDelegate, CLLocationManagerDelegate> { CLLocationManager *locationManager; IBOutlet MKMapView *googleMapView; } @property(nonatomic, retain) CLLocationManager *locationManager; @property(nonatomic, retain) MKMapView *googleMapView; @end One of my reasons for using them is so that I can use the setters in my viewDidUnload, I seem to be using @property a lot and was just wondering if the use in this situation is acceptable? -(void)viewDidUnload { [self setLocationManager:nil]; [self setGoogleMapView:nil]; [super viewDidUnload]; } much appreciated Gary

  • Killing a subprocess including its children from python

    - by user316664
    Hi, I'm using the subprocess module on python 2.5 to spawn a java program (the selenium server, to be precise) as follows: import os import subprocess display = 0 log_file_path = "/tmp/selenium_log.txt" selenium_port = 4455 selenium_folder_path = "/wherever/selenium/lies" env = os.environ env["DISPLAY"] = ":%d.0" % display command = ["java", "-server", "-jar", 'selenium-server.jar', "-port %d" % selenium_port] log = open(log_file_path, 'a') comm = ' '.join(command) selenium_server_process = subprocess.Popen(comm, cwd=selenium_folder_path, stdout=log, stderr=log, env=env, shell=True) This process is supposed to get killed once the automated tests are finished. I'm using os.kill to do this: os.killpg(selenium_server_process.pid, signal.SIGTERM) selenium_server_process.wait() This does not work. The reason is that the shell subprocess spawns another processfor the java program, and the pid of that process is unknown to my python code. I've tried killing the process group with os.killpg, but that kills also the python process which runs this code in the first place. Setting shell to false, thus avoiding the java program to run inside a shell environment, is also out of the question, due to other reasons. Does anyone have an idea how I can kill the shell and any other processes generated by it? Cheers, Ulas

  • deleting unaccessed files using python

    - by damon
    My django app parses some files uploaded by the user.It is possible that the file uploaded by the user may remain in the server for a long time ,without it being parsed by the app.This can increase in size if a lot of users upload a lot of files. I need to delete those files not recently parsed by the app -say not accessed for last 24 hours.I tried like this import os import time dirname = MEDIA_ROOT+my_folder filenames = os.listdir(dirname) filenames = [os.path.join(dirname,filename) for filename in filenames] for filename in filenames: last_access = os.stat(filename).st_atime #secs since epoch rtime = time.asctime(time.localtime(last_access)) print filename+'----'+rtime This shows the last accessed times for each file..But I am not sure how I can test if the file access time was within the last 24 hours..Can somebody help me out?

  • Please explain class methods

    I'm finding it difficult to understand when it is necessary to create class methods. From what I've read, they are important for creating new objects, but I do not see how.

  • mutliprocessing.Pool.add_sync() eating up memory

    - by Austin
    I want to use multithreading to make my script faster... I'm still new to this. The Python doc assumes you already understand threading and what-not. So... I have code that looks like this from itertools import izip from multiprocessing import Pool p = Pool() for i, j in izip(hugeseta, hugesetb): p.apply_async(number_crunching, (i, j)) Which gives me great speed! However, hugeseta and hugesetb are really huge. Pool keeps all of the _i_s and _j_s in memory after they've finished their job (basically, print output to stdout). Is there any to del i, and j after they complete?

  • How can i initialise a server on startup?

    - by djerry
    Hey all, I need to make some connections on startup of a server. I'm using the wcf technology for this client-server application. The problem is that the constructor of the server isn't called at any time, so for the moment, i initialize the connections when the first client makes a connection. But this generates problems in a further part. This is my server setup: private static ServiceHost _svc; static void Main(string[] args) { NetTcpBinding binding = new NetTcpBinding(SecurityMode.Message); Uri address = new Uri("net.tcp://localhost:8000"); _svc = new ServiceHost(typeof(MonitoringSystemService), address); publishMetaData(_svc, "http://localhost:8001"); _svc.AddServiceEndpoint(typeof(IMonitoringSystemService), binding, "Monitoring Server"); _svc.Open(); Console.WriteLine("Listener service gestart op net.tcp://localhost:8000/Monitoring"); Console.ReadLine(); } private static void publishMetaData(ServiceHost svc, string sEndpointAddress) { ServiceMetadataBehavior smb = svc.Description.Behaviors.Find<ServiceMetadataBehavior>(); if (smb != null) { smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); } else { smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; smb.HttpGetUrl = new Uri(sEndpointAddress); svc.Description.Behaviors.Add(smb); } } How can i start the server without waiting for a client to logon so i can initialize it. Thanks in advance.

  • python - selenium script syntax error

    Okay, I used selenium to test some automation, which I got to work. I did an export of the script for python. When I tried to run the python script it generated, it gave me a "SyntaxError: invalid syntax" error message. Here's the python script in question: from selenium import selenium import unittest, time, re class WakeupCall(unittest.TestCase): def setUp(self): self.verificationErrors = [] self.selenium = selenium("localhost", 4444, "*chrome", "http://the.web.site") self.selenium.start() def test_wakeup_call(self): sel = self.selenium sel.open("/index.php#deposit") sel.wait_for_page_to_load("30000") sel.click("link=History") sel.wait_for_page_to_load("30000") try: self.failUnless(sel.is_text_present("key phrase number 1.")) except AssertionError, e: self.verificationErrors.append(str(e)) The last line is what generated the "SyntaxError: invalid syntax" error message. A "^" was under the comma. The rest of the script goes as follows: def tearDown(self): self.selenium.stop() self.assertEqual([], self.verificationErrors) if name == "main": unittest.main()

  • Getting the type of an array of T, without specifying T - Type.GetType("T[]")

    - by Merlyn Morgan-Graham
    I am trying to create a type that refers to an array of a generic type, without specifying the generic type. That is, I would like to do the equivalent of Type.GetType("T[]"). I already know how to do this with a non-array type. E.g. Type.GetType("System.Collections.Generic.IEnumerable`1") // or typeof(IEnumerable<>) Here's some sample code that reproduces the problem. using System; using System.Collections.Generic; public class Program { public static void SomeFunc<T>(IEnumerable<T> collection) { } public static void SomeArrayFunc<T>(T[] collection) { } static void Main(string[] args) { Action<Type> printType = t => Console.WriteLine(t != null ? t.ToString() : "(null)"); Action<string> printFirstParameterType = methodName => printType( typeof(Program).GetMethod(methodName).GetParameters()[0].ParameterType ); printFirstParameterType("SomeFunc"); printFirstParameterType("SomeArrayFunc"); var iEnumerableT = Type.GetType("System.Collections.Generic.IEnumerable`1"); printType(iEnumerableT); var iEnumerableTFromTypeof = typeof(IEnumerable<>); printType(iEnumerableTFromTypeof); var arrayOfT = Type.GetType("T[]"); printType(arrayOfT); // Prints "(null)" // ... not even sure where to start for typeof(T[]) } } The output is: System.Collections.Generic.IEnumerable`1[T] T[] System.Collections.Generic.IEnumerable`1[T] System.Collections.Generic.IEnumerable`1[T] (null) I'd like to correct that last "(null)". This will be used to get an overload of a function via reflections by specifying the method signature: var someMethod = someType.GetMethod("MethodName", new[] { typeOfArrayOfT }); // ... call someMethod.MakeGenericMethod some time later I've already gotten my code mostly working by filtering the result of GetMethods(), so this is more of an exercise in knowledge and understanding.

  • How do I use python wx:Config to access the Windows registry?

    - by GreenAsJade
    I've read http://wxpython.org/docs/api/wx.ConfigBase-class.html I've done some basic things like the appended. What I can see is that Config.Create() returns me some sort of configuration object, which has information about python in it. But clearly that's not what I'm looking for: I seem to be missing the magic to say "give me a Config that is the Windows Registry"... Thanks! GaJ import wx from wx import Config app=wx.App(False) config=Config.Create() config.HasGroup("HKEY_CURRENT_USER") False config.GetFirstEntry() (0, u'', -1) config.GetFirstGroup() (1, u'PythonCore', 1) config.GetNextGroup(1) (0, u'', -1) config.GetNumberOfGroups() 1 config.GetPath() u'' config.HasEntry("PythonCore") False config.GetFirstGroup() (1, u'PythonCore', 1)

  • The HTTP verb POST used to access path '[my path]' is not allowed.

    - by Jed
    I am receiving an error that states: "The HTTP verb POST used to access path '[my path]' is not allowed.". The error is being caused by the fact that I am implementing an HTML form element that uses the POST method and does not explicitly define an .aspx page in its ACTION parameter. For example: <form action="" method="post"> <input type="submit" /> </form> The HTML above is on a file at "/foo/default.aspx". Now, if the user points the URL to the root directory "foo" without specifying the aspx file (i.e. "http://localhost/foo") and then submits the form, the error "The HTTP verb POST used to access path '/foo' is not allowed." will be thrown. However, if the user goes to "http://localhost/foo/default.aspx" and then submits the form, all goes well (even if the ACTION parameter is left empty). Note: If I explicitly add the name of the .aspx (default.aspx) page to the ACTION parameter, no errors are thrown. So the example below works fine regardless if the user defines the name of the file in the URL or not. <form action="default.aspx" method="post"> <input type="submit" /> </form> I was curious as to why the error was being thrown, so I read a Microsoft KB that states This problem occurs because a client makes an HTTP request by sending the POST method to a static HTML page. Static HTML pages do not support the POST method. I suppose the core of the explanation makes sense, however in my case, my form is not being sent to a static html page - it's being sent to the same page that the html form lives on (default.aspx)... this is implicit to an ACTION param that is left empty. Is it possible to configure IIS (or otherwise) that will allow us to do form POSTing and keep the ACTION param empty?

  • How to determine on which file system a file was created in Java

    - by rafrafUk
    Hi Everyone! I get files in different formats coming from different systems that I need to import into our database. Part of the import process it to check the line length to make sure the format is correct. We seem to be having issues with files coming from UNIX systems where one character is added. I suspect this is due to the return carriage being encoded differently on UNIX and windows platform. Is there a way to detect on which file system a file was created, other than checking the last character on the line? Or maybe a way of reading the files as text and not binary which I suspect is the issue? Thanks Guys !

  • How do I pull `static final` constants from a Java class into a Clojure namespace?

    - by Joe Holloway
    I am trying to wrap a Java library with a Clojure binding. One particular class in the Java library defines a bunch of static final constants, for example: class Foo { public static final int BAR = 0; public static final int SOME_CONSTANT = 1; ... } I had a thought that I might be able to inspect the class and pull these constants into my Clojure namespace without explicitly def-ing each one. For example, instead of explicitly wiring it up like this: (def *foo-bar* Foo/BAR) (def *foo-some-constant* Foo/SOME_CONSTANT) I'd be able to inspect the Foo class and dynamically wire up *foo-bar* and *foo-some-constant* in my Clojure namespace when the module is loaded. I see two reasons for doing this: A) Automatically pull in new constants as they are added to the Foo class. In other words, I wouldn't have to modify my Clojure wrapper in the case that the Java interface added a new constant. B) I can guarantee the constants follow a more Clojure-esque naming convention I'm not really sold on doing this, but it seems like a good question to ask to expand my knowledge of Clojure/Java interop. Thanks

  • ValueError: setting an array element with a sequence.

    - by MedicalMath
    This code: import numpy as p def firstfunction(): UnFilteredDuringExSummaryOfMeansArray = [] MeanOutputHeader=['TestID','ConditionName','FilterType','RRMean','HRMean','dZdtMaxVoltageMean','BZMean','ZXMean' ,'LVETMean','Z0Mean','StrokeVolumeMean','CardiacOutputMean','VelocityIndexMean'] dataMatrix = BeatByBeatMatrixOfMatrices[column] roughTrimmedMatrix = p.array(dataMatrix[1:,1:17]) trimmedMatrix = p.array(roughTrimmedMatrix,dtype=p.float64) myMeans = p.mean(trimmedMatrix,axis=0,dtype=p.float64) conditionMeansArray = [TestID,testCondition,'UnfilteredBefore',myMeans[3], myMeans[4], myMeans[6], myMeans[9] , myMeans[10], myMeans[11], myMeans[12], myMeans[13], myMeans[14], myMeans[15]] UnFilteredDuringExSummaryOfMeansArray.append(conditionMeansArray) secondfunction(UnFilteredDuringExSummaryOfMeansArray) return def secondfunction(UnFilteredDuringExSummaryOfMeansArray): RRDuringArray = p.array(UnFilteredDuringExSummaryOfMeansArray,dtype=p.float64)[1:,3] return firstfunction() Throws this error message: File "mypath\mypythonscript.py", line 3484, in secondfunction RRDuringArray = p.array(UnFilteredDuringExSummaryOfMeansArray,dtype=p.float64)[1:,3] ValueError: setting an array element with a sequence. However, this code works: import numpy as p a=range(24) b = p.reshape(a,(6,4)) c=p.array(b,dtype=p.float64)[:,2] I re-arranged the code a bit to put it into a cogent posting, but it should more or less have the same result. Can anyone show me what to do to fix the problem in the broken code above so that it stops throwing an error message?
