  • Selenium RC: How to click buttons that use onclick window.location?

    - by Andrew
    I have a button (outside of a form) that redirects to another page using the onclick attribute that calls window.location to redirect the user to another page. This time I can't change the HTML. I am using Safari 4 for testing. How can I click a button that uses the onclick attribute and window.location to redirect using Safari 4 and Selenium RC PHPUnit Extension? Here's my HTML: <input type="button" onclick="window.location='/registrations/new'" value="Start a new registration" id="create"> Update: Alternatively, I'm thinking about doing something where I assert that a location is specified in the window.location='', store that location, and call the open() command using that location. Not sure if this is an acceptable approach to testing this.

  • Why isn't my Ruby object deleted when the last reference goes out of scope?

    - by Andrew Clegg
    Hi gurus, I've found a weird effect when trying to track down a memory leak in a Rails app. Can anyone explain what's going on here? Save this script as a plain Ruby script (Rails not necessary): class Fnord def to_s 'fnord' end end def test f = Fnord.new end test GC.start sleep 2 ObjectSpace.each_object do |o| puts o if o.is_a? Fnord end When I run this via ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] I get the following: bash $ ruby var_test fnord Although the variable f is out of scope, there are no other references to the single Fnord object, and I've garbage collected, the object still seems to exist. Is this a nefarious memory leak of some sort, or am I completely missing something about Ruby? Further, if I change the test method to this: def test f = Fnord.new f = nil end I get no output. But surely this should not change the semantics here? Many thanks!

  • Vb6 project files and source safe

    - by Andrew
    A part of the application that I am working on is a legacy Vb6 Windows forms application. All the files in the project are under source control (VSS) except the Vb6 project file. From what I can establish from the other developers working on the project the reason for this is that the com components used in the projects have different references on each developers machine. I want to move the project files into VSS so that when files are added to the project these can be updated in the project files and other developers (and more importantly an automated build script) can get the latest project files from source safe. Does anyone know if/how I can achieve this in such a way as to not corrupt the references to other com components on different development machines?

  • Using Alias in Apache ONLY if local directory not present?

    - by Andrew E.
    Hey all, We're running a reseller web host, and aliasing a particular directory for ALL the sites within. This is all happening through WHM/Cpanel, which could possibly complicate my question. We want all hosts to run their "/concrete" directory through a shared location on the server. This is working fine by adding "Alias /concrete/ "/usr/local/share/concrete5/concrete-latest/concrete/" to the apache include editor in WHM. However, if a local concrete/ directory exists within the particular webroot of the virtual host, we'd rather use that than "/concrete" globally. It would also be nice if we could make this alias change in the context of the virtual host, within WHM (and I haven't found a great way to modify virtual host sections in WHM without hacking a file that I don't believe we're supposed to hack.) Thoughts?

  • routing in asp.net mvc.

    I have a route routes.MapRoute("BuildingProject", "BuildingProject/{action}/{id}", new { controller = "Home", action = "Index", id = "" }); i want it to behave like default route ie for url that starts with BuildingProject like http://localhost:4030/BuildingProject/DeleteAll.

  • Broadcastreceiver to obtain ServiceState information

    - by Andrew
    Hi, Does anyone know of a way to obtain the phone service state (IN_SERVICE, OUT_OF_SERVICE, EMERGENCY_ONLY, POWER_OFF) in android. I was hoping there would be a broadcastreciever to identify the changes, but I can't find anything. I know there's a listener but I'm not sure how I would use that from my app as it runs as a service using a WakefulIntentService (by thecommonsguy). With something like battery level (ie BATTERY_LOW, BATTERY_OKAY) it's quite easy, but I just can't work out a similar things for phone service changes.

  • Radio buttons being reset in FF on cache-refresh

    - by Andrew Song
    (This is technically an addendum to an earlier StackOverflow question I had posted, but my original post asked a different question which doesn't really cover this topic -- I don't want to edit my older question as I feel this is different enough to merit its own page) While browsing my website in Firefox 3.5 (and only FF3.5), I come across a page with two radio buttons that have the following HTML code: <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/> This page renders as expected, with 'check1' checked and 'check2' unchecked. When I then go to refresh the page by pressing Control + R, the two radio buttons render, but they are both unchecked even though the raw HTML code is the same (as above). If I do a cache-miss refresh (via Control + F5 or Control + Shift + R), the page returns back to the way you'd expect it. This is not a problem in any other browser I've tried except FF3.5. What is causing these radio buttons to be reset on a normal refresh? How can I avoid this?

  • .NET framework deprecated interfaces and attributes. What was your biggest refactoring due to lack o

    - by Andrew Florko
    Some .net-framework interfaces and attributes become obsolete and deprecated since new framework version appears. I am warned that such code may be removed or become unpredictable in next versions but have you ever faced the situation when you were forced to refactor code because code came uncompilable or start to behave weird? What was you biggest refactoring? Or maybe Microsoft always continued to support api's once they were published? Thank you in advance!

  • Can Win32_NetworkAdapterConfiguration.EnableStatic() be used to set more than one IP address?

    - by Andrew J. Brehm
    I ran into this problem in a Visual Basic program that uses WMI but could confirm it in PowerShell. Apparently the EnableStatic() method can only be used to set one IP address, despite taking two parameters IP address(es) and subnetmask(s) that are arrays. I.e. $a=get-wmiobject win32_networkadapterconfiguration -computername myserver This gets me an array of all network adapters on "myserver". After selecting a specific one ($a=$a[14] in this case), I can run $a.EnableStatic() which has this signature System.Management.ManagementBaseObject EnableStatic(System.String[] IPAddress, System.String[] SubnetMask) I thought this implies that I could set several IP addresses like this: $ips="192.168.1.42","192.168.1.43" $a.EnableStatic($ips,"255.255.255.0") But this call fails. However, this call works: $a.EnableStatic($ips[0],"255.255.255.0") It looks to me as if EnableStatic() really takes two strings rather than two arrays of strings as parameters. In Visual Basic it's more complicated and arrays must be passed but the method appears to take into account only the first element of each array. Am I confused again or is there some logic here?

  • Windows 8 Data Binding Bug - OnPropertyChanged Updates Wrong Object

    - by Andrew
    I'm experiencing some really weird behavior with data binding in Windows 8. I have a combobox set up like this: <ComboBox VerticalAlignment="Center" Margin="0,18,0,0" HorizontalAlignment="Right" Height="Auto" Width="138" Background="{StaticResource DarkBackgroundBrush}" BorderThickness="0" ItemsSource="{Binding CurrentForum.SortValues}" SelectedItem="{Binding CurrentForum.CurrentSort, Mode=TwoWay}"> <ComboBox.ItemTemplate> <DataTemplate> <TextBlock HorizontalAlignment="Right" Text="{Binding Converter={StaticResource SortValueConverter}}"/> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> Inside of a page with the DataContext set to a statically located ViewModel. When I change that ViewModel's CurrentForm attribute, who's property is implemented like this... public FormViewModel CurrentForm { get { return _currentForm; } set { _currentForm = value; if (!_currentForm.IsLoaded) { _currentSubreddit.Refresh.Execute(null); } RaisePropertyChanged("CurrentForm"); } } ... something really strange happens. The previous FormViewModel's CurrentSort property is changed to the new FormViewModel's current sort property. This happens as the RaisePropertyChanged event is called, through a managed-to-native transition, with native code invoking the setter of CurrentSort of the previous FormViewModel. Does that sound like a bug in Win8's data binding? Am I doing something wrong?

  • Azure Table Storage rejects an entity with a Property whose value is an Interface

    - by Andrew B Schultz
    I have a type called "Comment" that I'm saving to Azure Table Storage. Since a comment can be about any number of other types, I created an interface which all of these types implement, and then put a property of type ICommentable on the comment. So Comment has a property called About of type ICommentable. When I try to save a Comment to Azure Table Storage, if the Comment.About property has a value, I get the worthless invalid input error. However, if there is no value for Comment.About, I have no problem. Why would this be? Comment.About is not the only property that is a reference type. For example, Comment.From is a reference type, but the Comment.About is the only property of a type that is an interface. Fails: var comment = new Comment(); comment.CommentText = "It fails!"; comment.PartitionKey = "TEST"; comment.RowKey = "TEST123"; comment.About = sow1; comment.From = person1; Works: var comment = new Comment(); comment.CommentText = "It works!"; comment.PartitionKey = "TEST"; comment.RowKey = "TEST123"; //comment.About = sow1; comment.From = person1; Thanks!

  • C# StringBuilder question

    - by andrew
    in a C# file i have a class Archiver { [DllImport("Archiver.dll")] public static extern void archive(string data, StringBuilder response); } string data is an input, and StringBuilder response is where the function writes something the archive function prototype (written in C) looks like this: void archive(char * dataChr, char * outChr); and it receives a string in dataChr, and then does a strcpy(outChr,"some big text"); from C# i call it something like this: string message = "some text here"; StringBuilder response = new StringBuilder(10000); Archiver.archive(message,response); this works, but the problem, as you might see is that i give a value to the StringBuilder size, but the archive function might give back a (way) larger text than the size i've given to my StringBuilder. any way to fix this?

  • PHP5 getrusage() returning incorrect information?

    - by Andrew
    I'm trying to determine CPU usage of my PHP scripts. I just found this article which details how to find system and user CPU usage time (Section 4). However, when I tried out the examples, I received completely different results. The first example: sleep(3); $data = getrusage(); echo "User time: ". ($data['ru_utime.tv_sec'] + $data['ru_utime.tv_usec'] / 1000000); echo "System time: ". ($data['ru_stime.tv_sec'] + $data['ru_stime.tv_usec'] / 1000000); Results in: User time: 29.53 System time: 2.71 Example 2: for($i=0;$i<10000000;$i++) { } // Same echo statements Results: User time: 16.69 System time: 2.1 Example 3: $start = microtime(true); while(microtime(true) - $start < 3) { } // Same echo statements Results: User time: 34.94 System time: 3.14 Obviously, none of the information is correct except maybe the system time in the third example. So what am I doing wrong? I'd really like to be able to use this information, but it needs to be reliable. I'm using Ubuntu Server 8.04 LTS (32-bit) and this is the output of php -v: PHP 5.2.4-2ubuntu5.10 with Suhosin-Patch 0.9.6.2 (cli) (built: Jan 6 2010 22:01:14) Copyright (c) 1997-2007 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies

  • How do I tell which account is trying to access an ASP.NET web service?

    - by Andrew Lewis
    I'm getting a 401 (access denied) calling a method on an internal web service. I'm calling it from an ASP.NET page on our company intranet. I've checked all the configuration and it should be using integrated security with an account that has access to that service, but I'm trying to figure out how to confirm which account it's connecting under. Unfortunately I can't debug the code on the production network. In our dev environment everything is working fine. I know there has to be a difference in the settings, but I'm at a loss with where to start. Any recommendations?

  • How to save email as draft in Outlook 2003 programmatically?

    - by Andrew
    I am working on an VB.NET app which constructs emails programmatically. This app can be used by different people at the same time so I thought that having a "central" email mailbox would be appropriate. The users would then have "links" (not sure of the correct term) to that central mailbox through their local copy of Outlook. I want to be able to save these emails so that all users can see the generated emails in the "Drafts" folder of their Outlook so that they can check the emails first for any errors and then send it off. I was originally simply talking directly to the Outlook app on the server using Microsoft.Office.Interop but have since read that it is not recommended for use in this sort of scenario. Any ideas?

  • Intel MKL memory management and exceptions

    - by Andrew
    Hello everyone, I am trying out Intel MKL and it appears that they have their own memory management (C-style). They suggest using their MKL_malloc/MKL_free pairs for vectors and matrices and I do not know what is a good way to handle it. One of the reasons for that is that memory-alignment is recommended to be at least 16-byte and with these routines it is specified explicitly. I used to rely on auto_ptr and boost::smart_ptr a lot to forget about memory clean-ups. How can I write an exception-safe program with MKL memory management or should I just use regular auto_ptr's and not bother? Thanks in advance. EDIT http://software.intel.com/sites/products/documentation/hpc/mkl/win/index.htm this link may explain why I brought up the question UPDATE I used an idea from the answer below for allocator. This is what I have now: template <typename T, size_t TALIGN=16, size_t TBLOCK=4> class aligned_allocator : public std::allocator<T> { public: pointer allocate(size_type n, const void *hint) { pointer p = NULL; size_t count = sizeof(T) * n; size_t count_left = count % TBLOCK; if( count_left != 0 ) count += TBLOCK - count_left; if ( !hint ) p = reinterpret_cast<pointer>(MKL_malloc (count,TALIGN)); else p = reinterpret_cast<pointer>(MKL_realloc((void*)hint,count,TALIGN)); return p; } void deallocate(pointer p, size_type n){ MKL_free(p); } }; If anybody has any suggestions, feel free to make it better.

  • Is it worth investing time in learning to use emacs?

    - by Andrew
    Right up front: I do not want to start a religious war. I've used vi for as long as I can remember, and the few times I've tried to pick up emacs I've been so lost so quickly I've given up. Lots of people find emacs very powerful, however. Its programmability is somewhat legendary. I'm primarily doing Solaris+Java development, and I'd like to ask a simple question: will my productivity increase if I invest time in getting my head around emacs? Is the functionality that it offers over vim going to be paid back in productivity increases in a reasonable timeframe? Repeat: I don't want a "my editor is better than yours". I just want a yes or no answer as to whether it's worth investing the time or not. Will my productivity really increase?

  • mysql_query -- question about results "location"

    - by Andrew Heath
    Forgive me if this is a particularly stupid question! mysql_query($query) returns a boolean, but you can also assign it to a variable $results = mysql_query($query) and then use the other mysql_ functions to extract data. Out of curiosity, how does mysq_query($query) act as both a boolean and a data container at the same time? What's happening "under the hood" during these steps? (yes, I am a n00b..., please be kind!)

  • wordpress servlet mapping not working

    - by Andrew
    I have the latest wordpress running in tomcat 6.0.26 virtual host with Quercus Servlet php servlet. It works, except when I try to use perm links. A url such as /index.php/my-page-name doesn't seem to ever hit the php server. It gets a browser error that request resource is not available. It's like it isn't matching the servlet urlmapping. I'm using a standard method in the web.xml <servlet-mapping> <servlet-name>Quercus Servlet</servlet-name> <url-pattern>*.php</url-pattern> </servlet-mapping> I see nothing showing up either in the tomcat logs when I use that url above. Any ideas please?
