  • How to iterate with Selenium RC over XPath results directly?

    - by Gj
    I'm currently resorting to first doing a get_xpath_count, and then creating a loop incrementing an index variable, which in turn I inject back into the original xpath to select the nth result... very awkward no doubt. Is there some simple, direct, elegant way to iterate directly over the xpath results? Thanks!

  • Issue building C++ DLL with Visual Studio 2010

    - by Jon Tackabury
    I have a very simple DLL written in unmanaged C++ that I access from my application. I recently switch to Visual Studio 2010, and the DLL went from 55k down to 35k with no code changes, and now it will no longer load in Windows 2000. I didn't change any code or compiler settings. I have my defines setup for 0x0500, which should include Windows 2000 support. Has anyone else run into this, or have any ideas of what I can do?

  • java web application best practices

    - by Bruce
    Hi all I'm trying to figure out the optimum way to develop and release a fairly simple web application, and I'm running into several problems. I'll outline the decisions I've made, because somewhere I've clearly gone off the rails.. Hugely grateful for any help! I have what I think is a fairly simple web application. It contains a couple of jsps that reference a couple of java beans, and the usual static html, js, css and images. Decision 1) I wanted to have a clear and clean release procedure, such that I could develop on my local machine and then release reliably to a production machine. I therefore made the decision to package the application into a war file (including all the static resources), to minimize the separate bits and pieces I would need to release. So far so good? Decision 2) I wanted things on my local machine to be as similar as possible to the production environment. So in my html, for example, I may have a reference to a static file such as http://static.foo.com/file . To keep this code working seamlessly on dev and prod, I decided to put static.foo.com in my /etc/hosts when developing locally, so that all the urls work correctly without changing anything. Decision 3) I decided to use eclipse and maven to give me a best practice environment for administering and building my project. So I have a nice tight set up now, except that: Every time I want to change anything in development, like one line in an html file, I have to rebuild the entire project and then wait for tomcat to load the war before I can see if it's what I wanted. So my questions are: 1) Is there a way to connect up eclipse and tomcat so that I don't have to rebuild the war each time? ie tomcat is looking straight at my actual workspace to serve up the static files? 2)I think I'm maybe making things harder by using /etc/hosts to reflect production urls - is there a better way that doesn't involve manually changing over urls (relative urls are fine of course, but where you have many subdomains, say one for static files and one for dynamic, you have to write out the full path, surely?) 3) Is this really best practice?? How do people set things up so that they balance the requirement for an automated, all-encompassing build process on the one hand, and the speed and flexibility to be able to develop javascript and html and css quickly, as quickly as if one just pointed apache at the directory and developed live? What do people find works? Many thanks!

  • WPF - Two way binding use a user control...binding to object, not an element!

    - by Scott
    I created an object with a simple property with a default value. I then created a user control that has a text box in it. I set the datacontext of the user control to the object. The text box correctly shows the properties default value but I can't seem to update the property value when the user changes the text box value. I created a simple project to illustrate my code. Thanks for the help!! public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); } private string _titleValue; public string TitleValue { get { return _titleValue; } set { _titleValue = value; textBox1.Text = _titleValue; } } public static readonly DependencyProperty TitleValueProperty = DependencyProperty.Register( "TitleValue", typeof(string), typeof(UserControl1), new FrameworkPropertyMetadata(new PropertyChangedCallback(titleUpdated)) ); //Don't think I should need to do this!!! private static void titleUpdated(DependencyObject d, DependencyPropertyChangedEventArgs e) { ((UserControl1)d).TitleValue = (string)e.NewValue; } } <UserControl x:Class="WpfApplication1.UserControl1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300"> <Grid> <TextBox Height="23" HorizontalAlignment="Left" Margin="94,97,0,0" Name="textBox1" VerticalAlignment="Top" Width="120" Text="{Binding Path=TitleValue, Mode=TwoWay}"/> </Grid> </UserControl> public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); var dummy = new DummyObject("This is my title."); userControl11.DataContext = dummy; } private void button1_Click(object sender, RoutedEventArgs e) { MessageBox.Show("The value is: " + ((DummyObject)userControl11.DataContext).Title); } } <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:WpfApplication1"> <Grid> <my:UserControl1 HorizontalAlignment="Left" Margin="95,44,0,0" x:Name="userControl11" VerticalAlignment="Top" Height="191" Width="293" TitleValue="{Binding Path=Title, Mode=TwoWay}"/> <Button Content="Check Value" Height="23" HorizontalAlignment="Left" Margin="20,12,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" /> </Grid> </Window>

  • Design patterns and interview question

    - by user160758
    When I was learning to code, I read up on the design patterns like a good boy. Long after this, I started to actually understand them. Design discussions such as those on this site constantly try to make the rules more and more general, which is good. But there is a line, over which it becomes over-analysis starts to feed off itself and as such I think begins to obfuscate the original point - for example the "What's Alternative to Singleton" post and the links contained therein. http://stackoverflow.com/questions/1300655/whats-alternative-to-singleton I say this having been asked in both interviews I’ve had over the last 2 weeks what a singleton is and what criticisms I have of it. I have used it a few times for items such as user data (simple key-value eg. last file opened by this user) and logging (very common i'm sure). I've never ever used it just to have what is essentially global application data, as this is clearly stupid. In the first interview, I reply that I have no criticisms of it. He seemed disappointed by this but as the job wasn’t really for me, I forgot about it. In the next one, I was asked again and, as I wanted this job, I thought about it on the spot and made some objections, similar to those contained in the post linked to above (I suggested use of a factory or dependency injection instead). He seemed happy with this. But my problem is that I have used the singleton without ever using it in this kind of stupid way, which I had to describe on the spot. Using it for global data and the like isn’t something I did then realised was stupid, or read was stupid so didn’t do, it was just something I knew was stupid from the start. Essentially I’m supposed to be able to think of ways of how to misuse a pattern in the interview? Which class of programmers can best answer this question? The best ones? The medium ones? I'm not sure.... And these were both bright guys. I read more than enough to get better at my job but had never actually bothered to seek out criticisms of the most simple of the design patterns like this one. Do people think such questions are valid and that I ought to know the objections off by heart? Or that it is reasonable to be able to work out what other people who are missing the point would do on the fly? Or do you think I’m at least partially right that the question is too unsubtle and that the questions ought to be better thought out in order to make sure only good candidates can answer. PS. Please don’t think I’m saying that I’m just so clever that I know everything automatically - I’ve learnt the hard way like everyone else. But avoiding global data is hardly revolutionary.

  • Create and display indoor map on Android

    - by Lorenzo Barbagli
    I'm developing an Android application and I would like to display an internal (indoor) map of some buildings, but I don't know where to begin: I want to create a custom kml file (how it's possible to create it? with which tool?) and display it in a fragment. I already have it working with external maps (simple GoogleMap in MapFragment), so it would be super to have the kml file placed 'over' the GoogleMap, like real indoor maps. Thanks

  • Saving data in custom class via AppDelegate

    - by redspike
    I can't seem to save data to a custom instance object in my AppDelegate. My custom class is very simple and is as follows: Person.h ... @interface Person : NSObject { int _age; } - (void) setAge: (int) age; - (int) age; @end Person.m #import "Person.h" @implementation Person - (void) setAge:(int) age { _age = age; } - (int) age { return _age; } @end I then create an instance of Person in the AppDelegate class: AppDelegate.h @class Person; @interface AccuTaxAppDelegate : NSObject <UIApplicationDelegate> { ... Person *person; } ... @property (nonatomic, retain) Person *person; @end AppDelegate.m ... #import "Person.h" @implementation AccuTaxAppDelegate ... @synthesize person; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } - (void)applicationWillTerminate:(UIApplication *)application { // Save data if appropriate } #pragma mark - #pragma mark Memory management - (void)dealloc { [navigationController release]; [window release]; [person release]; [super dealloc]; } @end Finally, in my ViewController code I grab a handle on AppDelegate and then grab the person instance, but when I try to save the age it doesn't seem to work: MyViewController ... - (void)textFieldDidEndEditing:(UITextField *)textField { NSString *textAge = [textField text]; int age = [textAge intValue]; NSLog(@"Age from text field::%i", age); AppDelegate *appDelegate = (AppDelegate *)[UIApplication sharedApplication].delegate; Person *myPerson = (Person *)[appDelegate person]; NSLog(@"Age before setting: %i", [myPerson age]); [myPerson setAge:age]; NSLog(@"Age after setting: %i", [myPerson age]); [textAge release]; } ... The output of the above NSLogs are: [Session started at 2010-05-04 18:29:22 +0100.] 2010-05-04 18:29:28.260 AccuTax[16235:207] Age in text field:25 2010-05-04 18:29:28.262 AccuTax[16235:207] Age before setting: 0 2010-05-04 18:29:28.263 AccuTax[16235:207] Age after setting: 0 Any ideas why 'age' isn't being stored? I'm relatively new to Obj-C so please forgive me if I'm missing something very simple!

  • Need ad-hoc reporting component

    - by Nelson
    We need some simple ad-hoc reporting solution for our ASP.NET web-site. Just an ability to build a query with user friendly interface, then show the result of this query in some table and maybe export it to Excel or print. The solution must be quite easy for end users (our site visitors) who know nothing about databases, SQL and other tech stuff.

  • How to add a MIME handler to Firefox and Internet Explorer from an installer

    - by JustSmith
    I'm looking to create an installer that will add a handler for a MIME type in Firefox and Explorer. The installer I will be using will be either INNO (a.k.a Oh Nooo!) or NSIS. How do Mozilla and Microsoft recommend adding a handler. So far all I have been able to find for Firefox is how to Add/Remove/Augment manually which no matter how simple is something I would like to hide from the user.

  • How to package Qt Framework on Mac OS X?

    - by Chris Kaminski
    I'm developing an application for the Mac, and I'm wicked new at this - what would be the best way to distribute the Qt Framework so that I'm not impacting an already existing framework, and so that my App.app picks up the libraries. I'm also using boost, so I'm curious how a simple bundle works with libraries.

  • Ruby: Parse, replace, and evaluate a string formula

    - by Swartz
    I'm creating a simple Ruby on Rails survey application for a friend's psychological survey project. So we have surveys, each survey has a bunch of questions, and each question has one of the options participants can choose from. Nothing exciting. One of the interesting aspects is that each answer option has a score value associated with it. And so for each survey a total score needs to be calculated based on these values. Now my idea is instead of hard-coding calculations is to allow user add a formula by which the total survey score will be calculated. Example formulas: "Q1 + Q2 + Q3" "(Q1 + Q2 + Q3) / 3" "(10 - Q1) + Q2 + (Q3 * 2)" So just basic math (with some extra parenthesis for clarity). The idea is to keep the formulas very simple such that anyone with basic math can enter them without resolving to some fancy syntax. My idea is to take any given formula and replace placeholders such as Q1, Q2, etc with the score values based on what the participant chooses. And then eval() the newly formed string. Something like this: f = "(Q1 + Q2 + Q3) / 2" # some crazy formula for this survey values = {:Q1 => 1, :Q2 => 2, :Q3 => 2} # values for substitution result = f.gsub(/(Q\d+)/) {|m| values[$1.to_sym] } # string to be eval()-ed eval(result) So my questions are: Is there a better way to do this? I'm open to any suggestions. How to handle formulas where not all placeholders were successfully replaced (e.g. one question wasn't answered)? Ex: {:Q3 = 2} wasn't in values hash? My idea is to rescue eval()... any thoughts? How to get proper result? Should be 2.5, but due to integer arithmetic, it will truncate to 2. I can't expect people who provide the correct formula (e.g. / 2.0 ) to understand this nuance. I do not expect this, but how to best protect eval() from abuse (e.g. bad formula, manipulated values coming in)? Thank you!

  • Equivalent to GetTickCount() on Linux

    - by Matt Joiner
    I'm looking for an equivalent to GetTickCount() on Linux. Presently I am using Python's time.time() which presumably calls through to gettimeofday(). My concern is that the time returned (the unix epoch), may change erratically if the clock is messed with, such as by NTP. A simple process or system wall time, that only increases positively at a constant rate would suffice. Does any such time function in C or Python exist?

  • Dynamically refresh JTextArea as processing occurs?

    - by digiarnie
    I am trying to create a very simple Swing UI that logs information onto the screen via a JTextArea as processing occurs in the background. When the user clicks a button, I want each call to: textArea.append(someString + "\n"); to immediately show up in the UI. At the moment, the JTextArea does not show all log information until the processing has completed after clicking the button. How can I get it to refresh dynamically?

  • Find last match with python regular expression

    I wanto to match the last occurence of a simple pattern in a string, e.g. list = re.findall(r"\w+ AAAA \w+", "foo bar AAAA foo2 AAAA bar2) print "last match: ", list[len(list)-1] however, if the string is very long, a huge list of matches is generated. Is there a more direct way to match the second occurence of "AAAA" or should I use this workaround?

  • How do I get the CPU speed and total physical ram in C#?

    - by edude05
    I need a simple way of checking how much ram and fast the CPU of the host PC is. I tried WMI however the code I'm using private long getCPU() { ManagementClass mObject = new ManagementClass("Win32_Processor"); mObject.Get(); return (long)mObject.Properties["MaxClockSpeed"].Value; } Throws a null reference exception. Furthermore, WMI queries are a bit slow and I need to make a few to get all the specs. Is there a better way?

  • Are there algorithms for increasing resolution of an image?

    - by David
    Are there any algorithms or tools that can increase the resolution of an image - besides just a simple zoom that makes each individual pixel in the image a little larger? I realize that such an algorithm would have to invent pixels that don't really exist in the original image, but I figured there might be some algorithm that could intelligently figure out what pixels to add to the image to increase its resolution.

  • Javascript Mp3 Player, NONE FLASH

    - by Yo Momma
    I currently have a simple flash Mp3 player on my site which works lovely. The issue is, most cell phones do not support flash and a large portion of my visitors come through via a mobile device. The alternative to this is to replace the flash player with a javascript player. I found a JQuery one but it only works on HTML5 compatible browsers. Does anyone know of a good alternative that would work on mobile devices as well as most desktop web browsers?
