  • How to measure Silverlight control load time with Google Analytics

    - by ddehghan
    Hi everyone I have a simple silverlight page for for finding available domain names. I use Google Analytics for monitoring the traffic. I would really like to find out how long it take for users to download and render the Silverlight control. Once the java script on a page is loaded there should be a way to start a timer and then stop the timer once the Silverlight control is loaded. Key points I would like to measure are: Time it takes to download the silverlight control Time it takes to initialize the control Thanks

  • Mutable objects and hashCode

    - by robert
    Have the following class: public class Member { private int x; private long y; private double d; public Member(int x, long y, double d) { this.x = x; this.y = y; this.d = d; } @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + x; result = (int) (prime * result + y); result = (int) (prime * result + Double.doubleToLongBits(d)); return result; } @Override public boolean equals(Object obj) { if (this == obj) { return true; } if (obj instanceof Member) { Member other = (Member) obj; return other.x == x && other.y == y && Double.compare(d, other.d) == 0; } return false; } public static void main(String[] args) { Set<Member> test = new HashSet<Member>(); Member b = new Member(1, 2, 3); test.add(b); System.out.println(b.hashCode()); b.x = 0; System.out.println(b.hashCode()); Member first = test.iterator().next(); System.out.println(test.contains(first)); System.out.println(b.equals(first)); System.out.println(test.add(first)); } } It produces the following results: 30814 29853 false true true Because the hashCode depends of the state of the object it can no longer by retrieved properly, so the check for containment fails. The HashSet in no longer working properly. A solution would be to make Member immutable, but is that the only solution? Should all classes added to HashSets be immutable? Is there any other way to handle the situation? Regards.

  • C# 'could not found' existing method

    - by shybovycha
    Greetings! I've been fooling around (a bit) with C# and its assemblies. And so i've found such an interesting feature as dynamic loading assemblies and invoking its class members. A bit of google and here i am, writing some kind of 'assembly explorer'. (i've used some portions of code from here, here and here and none of 'em gave any of expected results). But i've found a small bug: when i tried to invoke class method from assembly i've loaded, application raised MissingMethod exception. I'm sure DLL i'm loading contains class and method i'm tryin' to invoke (my app ensures me as well as RedGate's .NET Reflector): The main application code seems to be okay and i start thinking if i was wrong with my DLL... Ah, and i've put both of projects into one solution, but i don't think it may cause any troubles. And yes, DLL project has 'class library' target while the main application one has 'console applcation' target. So, the question is: what's wrong with 'em? Here are some source code: DLL source: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ClassLibrary1 { public class Class1 { public void Main() { System.Console.WriteLine("Hello, World!"); } } } Main application source: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { Assembly asm = Assembly.LoadFrom(@"a\long\long\path\ClassLibrary1.dll"); try { foreach (Type t in asm.GetTypes()) { if (t.IsClass == true && t.FullName.EndsWith(".Class1")) { object obj = Activator.CreateInstance(t); object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, obj, null); // Exception is risen from here } } } catch (Exception e) { System.Console.WriteLine("Error: {0}", e.Message); } System.Console.ReadKey(); } } } UPD: worked for one case - when DLL method takes no arguments: DLL class (also works if method is not static): public class Class1 { public static void Main() { System.Console.WriteLine("Hello, World!"); } } Method invoke code: object res = t.InvokeMember("Main", BindingFlags.Default | BindingFlags.InvokeMethod, null, null, null);

  • Very difficult question !

    - by cibercitizen1
    I'm absolutely impressed by how fast the questions are answered. Some guys seems to be spending all day long waiting for questions: congratulations ! Your help is very appreciated, really. but ... I guess you don't work, don't have friends, or family, even you don't sleep at all? Do you? Or how do you manage to be so fast?

  • c++ multithread array

    - by user1731972
    i'm doing something for fun, trying to learn multithreading Problems passing array by reference to threads but Arno pointed out that my threading via process.h wasn't going to be multi-threaded. What I'm hoping to do is something where I have an array of 100 (or 10,000, doesn't really matter I don't think), and split up the assignment of values to each thread. Example, 4 threads = 250 values per thread to be assigned. Then I can use this filled array for further calculations. Here's some code I was working on (which doesn't work) #include <process.h> #include <windows.h> #include <iostream> #include <fstream> #include <time.h> //#include <thread> using namespace std; void myThread (void *dummy ); CRITICAL_SECTION cs1,cs2; // global int main() { ofstream myfile; myfile.open ("coinToss.csv"); int rNum; long numRuns; long count = 0; int divisor = 1; float holder = 0; int counter = 0; float percent = 0.0; HANDLE hThread[1000]; int array[10000]; srand ( time(NULL) ); printf ("Runs (use multiple of 10)? "); cin >> numRuns; for (int i = 0; i < numRuns; i++) { //_beginthread( myThread, 0, (void *) (array1) ); //??? //hThread[i * 2] = _beginthread( myThread, 0, (void *) (array1) ); hThread[i*2] = _beginthread( myThread, 0, (void *) (array) ); } //WaitForMultipleObjects(numRuns * 2, hThread, TRUE, INFINITE); WaitForMultipleObjects(numRuns, hThread, TRUE, INFINITE); } void myThread (void *param ) { //thanks goes to stockoverflow //http://stackoverflow.com/questions/12801862/problems-passing-array-by-reference-to-threads int *i = (int *)param; for (int x = 0; x < 1000000; x++) { //param[x] = rand() % 2 + 1; i[x] = rand() % 2 + 1; } } Can anyone explain why it isn't working?

  • How can I control my winmo phone?

    - by Christian W
    I have been trying to find a way to control my winmo phone from my pc. (HTC S740) What I want is to be able to call a number from an application, answer the phone from an application and hangup the phone from an application. It should also be able to track how long the ongoing call has been. Any libraries out there that lets me make such an application with C#? (The phone is connected to the pc via usb in Windows 7.)

  • Why this query is so slow?

    - by Silver Light
    This query appears in mysql slow query log: it takes 11 seconds. INSERT INTO record_visits ( record_id, visit_day ) VALUES ( '567', NOW() ); The table has 501043 records and it's structure looks like this: CREATE TABLE IF NOT EXISTS `record_visits` ( `id` int(11) NOT NULL AUTO_INCREMENT, `record_id` int(11) DEFAULT NULL, `visit_day` date DEFAULT NULL, `visit_cnt` bigint(20) DEFAULT '1', PRIMARY KEY (`id`), UNIQUE KEY `record_id_visit_day` (`record_id`,`visit_day`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 ; What could be wrong? Why this INSERT takes so long?

  • memset for initialization in C++

    memset is sometimes used to initialize data in a constructor like the example below. Does it work in general ? Is it a good idea in general? class A { public: A(); private: int a; float f; char str[35]; long *lp; }; A::A() { memset(this, 0, sizeof(*this)); }

  • JList with JScrollPane and prototype cell value wraps element names (replaces with dots instead of s

    - by Tom
    I've got a Jlist inside a JScrollPane and I've set a prototype value so that it doesn't have to calculate the width for big lists, but just uses this default width. Now, the problem is that the Jlist is for some reason replacing the end of an element with dots (...) so that a horizontal scrollbar will never be shown. How do I disable with "wrapping"? So that long elements are not being replaced with dots if they are wider than the Jlist's width? I've reproduced the issue in a small example application. Please run it if you don't understand what I mean: import javax.swing.*; import java.awt.*; public class Test { //window private static final int windowWidth = 450; private static final int windowHeight = 500; //components private JFrame frame; private JList classesList; private DefaultListModel classesListModel; public Test() { load(); } private void load() { //create window frame = new JFrame("Test"); frame.setSize(windowWidth, windowHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setUndecorated(true); frame.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG); //classes list classesListModel = new DefaultListModel(); classesList = new JList(classesListModel); classesList.setPrototypeCellValue("prototype value"); classesList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); classesList.setVisibleRowCount(20); JScrollPane scrollClasses = new JScrollPane(classesList, JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED, JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED); for (int i = 0; i < 200; i++) { classesListModel.addElement("this is a long string, does not fit in width"); } //panel JPanel drawingArea = new JPanel(); drawingArea.setBackground(Color.white); drawingArea.add(scrollClasses); frame.add(drawingArea); //set visible frame.setVisible(true); } } Even if you force horizontal scrollbar, you still won't be able to scroll because the element is actually not wider than the width because of the dot (...) wrapping. Thanks in advance.

  • Get color output in bash

    - by Werner
    Hi, when compiling some projects on linux terminal, I get usually a long output consisting of a lot of information. Usually this information is MONOCHROME. I wonder if bash can be modified somehow, so in all outputs or in some specific outputs (like from Makefile, etc) I can get different colors dependeing on, for instance: make[1]: Leaving directory or g++ -DHAVE_CONFIG_H -I. etc. Thanks

  • SVG Scaling Text to fit container

    This is likely a very simple question, but how do I get text in SVG to stretch to fit its container? I don't care if it looks ugly from being stretched too long or high, but it needs to fits its container and be as big as possible. Thanks

  • Scrum meeting - dealing with the last question

    - by Wizzard
    In the 5/15 minute scrum meeting the 3 questions are asked. For the last question "what impediments are getting in your way" If a dev has problems - the xyz is going to have problems, this is likely going to draw the meeting out past 15 mins and could go into a hour long discussion. Is it the scrum masters job to help this user, is there something to stop this from going on more than 15 mins. Thoughts?

  • is there a proper way to handle multiple errors/exceptions?

    - by toPeerOrNotToPeer
    in OO programming, is there some conceptual pattern, ideas, about handling multiple errors? for example, i have a method that performs some checks and should return an error message for each error found ['name is too short', 'name contains invalid unicode sequences', 'name is too long'] now, should i use an array of exceptions (not thrown exceptions)? or something like this is better: class MyExceptionList extends Exception{ public Void addException(Exception e){} public Array getExceptions(){} } any theory behind this argument will be appreciated! (this isn't a request about a specific programming language, but a pure theoretical one) thank you in advance

  • Download a file using cocoa

    Hi All, I want to download a file to the downloads folder. I searched google for this and found the NSURLDownload class. I've read the page in the dev center and created this code (with some copy and pasting) this code: @implementation Downloader @synthesize downloadResponse; - (void)startDownloadingURL:(NSString*)downloadUrl destenation:(NSString*)destenation { // create the request NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:downloadUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create the connection with the request // and start loading the data NSURLDownload *theDownload=[[NSURLDownload alloc] initWithRequest:theRequest delegate:self]; if (!theDownload) { NSLog(@"Download could not be made..."); } } - (void)download:(NSURLDownload *)download decideDestinationWithSuggestedFilename:(NSString *)filename { NSString *destinationFilename; NSString *homeDirectory=NSHomeDirectory(); destinationFilename=[[homeDirectory stringByAppendingPathComponent:@"Desktop"] stringByAppendingPathComponent:filename]; [download setDestination:destinationFilename allowOverwrite:NO]; } - (void)download:(NSURLDownload *)download didFailWithError:(NSError *)error { // release the connection [download release]; // inform the user NSLog(@"Download failed!

  • Looking for early paper about compiling object-oriented code

    - by Robert Kosara
    I remember reading a paper a long time ago that talked about object-oriented programming. I believe that this was from the early 1980s or perhaps even before then. This was at the time when object-oriented programming was still done through pre-processors, and one thing that stuck with me is this: it argued that you could write code in either procedural or object-oriented fashion, and after preprocessing/compiling, you would end up with the exact same machine code. Does anybody know which paper I'm talking about?

  • UIWebView doesn't scroll to the bottom of the webpage loaded/created

    - by tom
    I have a UIWebView inside a normal UIViewController. The content of the UIWebView is programming/dynamically created in my program, and it could be very long (multiple table rows). Somehow, after loading, the page won't scroll more then one and half screen of content when swipe on the screen. Because of that I can only see the beginning few rows of data, but not the many others after them. Why is that?
