  • using ruby test and selenium grid how can I keep the same browser window for multiple tests?

    - by George Horlacher
    Each of my tests start a new selenium client browser and tear it down so they can run stand alone with this code: def setup if $selenium @selenium = $selenium else @selenium = Selenium::SeleniumDriver.new("#$sell_server", 4444, "#$browser", "http://#$network.#$host:2086", 10000); @selenium.start end @selenium.set_context("test_login") end def teardown @selenium.stop unless $selenium assert_equal [], @verification_errors end What I'd like is to run a suite of tests that all use the same browser and don't keep opening and closing new browsers for every test. I've tried using $selenium as a global object / browser but each test still opens up a new browser and closes it. How should this be done?

  • Swing's KeyListener and multiple keys pressed at the same time.

    - by Negai
    Hi everyone, is there any conventional way in swing of tracking down the events, when two keyboard keys are pressed at the same time? I have a couple of ideas e.g. remembering the key and event generation time so that we could in a consecutive event handler invocation check the time difference between these two events and decide, whether it's a two-button event or not. Phew. But it looks like a kludge. Thanks in advance.

  • one page has 9 urls. I am looking for 301 auto redirect syntax for multiple urls.

    - by Ali Demirtas
    Hi This is the third time I am asking this question. I am only looking for the syntax of how to solve this problem. I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engines penalize my website for this. Here are examples of a page with more than 2 urls (http://www.turkishfootballstore.com/lang-nl/product.php?id_product=515) (http://www.turkishfootballstore.com/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) (http://www.turkishfootballstore.com/lang-nl/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) you can see even the static url's have 2 one with language defined and the other without. out fo the three urls above the correct one is the one at the bottom. What can I do to solve this problem? I have no knowledge of programming. Here is the htaccess for the website. Any sample code or help is really appreciated. There is 550 pages and every page is published in 17 different languages I want to use a 301 auto redirect. What is the simplest way to do it? Please only reply if you have the coding for a auto 301 redirect!

  • Is it OK to open a DB4o file for query, insert, update multiple times?

    - by Khnle
    This is the way I am thinking of using DB4o. When I need to query, I would open the file, read and close: using (IObjectContainer db = Db4oFactory.OpenFile(Db4oFactory.NewConfiguration(), YapFileName)) { try { List<Pilot> pilots = db.Query<Pilot>().ToList<Pilot>(); } finally { try { db.Close(); } catch (Exception) { }; } } At some later time, when I need to insert, then using (IObjectContainer db = Db4oFactory.OpenFile(Db4oFactory.NewConfiguration(), YapFileName)) { try { Pilot pilot1 = new Pilot("Michael Schumacher", 100); db.Store(pilot1); } finally { try { db.Close(); } catch (Exception) { }; } } In this way, I thought I will keep the file more tidy by only having it open when needed, and have it closed most of the time. But I keep getting InvalidCastException Unable to cast object of type 'Db4objects.Db4o.Reflect.Generic.GenericObject' to type 'Pilot' What's the correct way to use DB4o?

  • How to pass multiple different records (not class due to delphi limitations) to a function?

    - by mingo
    Hi to all. I have a number of records I cannot convert to classes due to Delphi limitation (all of them uses class operators to implement comparisons). But I have to pass to store them in a class not knowing which record type I'm using. Something like this: type R1 = record begin x :Mytype; class operator Equal(a,b:R1) end; type R2 = record begin y :Mytype; class operator Equal(a,b:R2) end; type Rn = record begin z :Mytype; class operator Equal(a,b:Rn) end; type TC = class begin x : TObject; y : Mytype; function payload (n:TObject) end; function TC.payload(n:TObject) begin x := n; end; program: c : TC; x : R1; y : R2; ... c := TC.Create(): n:=TOBject(x); c.payload(n); Now, Delphi do not accept typecast from record to TObject, and I cannot make them classes due to Delphi limitation. Anyone knows a way to pass different records to a function and recognize their type when needed, as we do with class: if x is TMyClass then TMyClass(x) ... ???

  • In Rails, how can a record belong_to a single user, but also have multiple "secondary" users?

    - by Kuro
    In my app, I have a User model and a Project model. A user has_many assignments and each project belongs_to a user. But along with each project having an owner, the user who created it, I would like the owner be able to share it with others (so that the project gets shown on the other users' account along with their own). I imagine having to use has_many :through, and setting up a projects_users table with a user_id and a project_id. And I guess this would be the end result? Project.first.user # The creator of the project => #<User id: 1, name: 'andrew', etc...> Project.first.users # The users that the creator chose to share it with => [#<User id: 2 ...>, #<User id: 3 ...>] How would I go about doing this? Thanks!

  • [MFC] Creating multiple dialogs in an MFC app with no main Window, they become children of each othe

    - by John
    (title updated) Following on from this question, now I have a clearer picture what's going on... I have a MFC application with no main window, which exposes an API to create dialogs. When I call some of these methods repeatedly, the dialogs created are parented to each other instead of all being parented to the desktop... I have no idea why. But anyway even after creation, I am unable to change the parent back to NULL or CWnd::GetDesktopWindow()... if I call SetParent followed by GetParent, nothing has changed. So apart from the really weird question of why Windows is magically parenting each dialog to the last one created, is there anything I'm missing to be able to set these windows as children of the desktop? UPDATED: I have found the reason for all this, but not the solution. From my dialog constructor, we end up in: BOOL CDialog::CreateIndirect(LPCDLGTEMPLATE lpDialogTemplate, CWnd* pParentWnd, void* lpDialogInit, HINSTANCE hInst) { ASSERT(lpDialogTemplate != NULL); if (pParentWnd == NULL) pParentWnd = AfxGetMainWnd(); m_lpDialogInit = lpDialogInit; return CreateDlgIndirect(lpDialogTemplate, pParentWnd, hInst); } Note: if (pParentWnd == NULL)pParentWnd = AfxGetMainWnd(); The call-stack from my dialog constructor looks like this: mfc80d.dll!CDialog::CreateIndirect(const DLGTEMPLATE * lpDialogTemplate=0x005931a8, CWnd * pParentWnd=0x00000000, void * lpDialogInit=0x00000000, HINSTANCE__ * hInst=0x00400000) mfc80d.dll!CDialog::CreateIndirect(void * hDialogTemplate=0x005931a8, CWnd * pParentWnd=0x00000000, HINSTANCE__ * hInst=0x00400000) mfc80d.dll!CDialog::Create(const char * lpszTemplateName=0x0000009d, CWnd * pParentWnd=0x00000000) mfc80d.dll!CDialog::Create(unsigned int nIDTemplate=157, CWnd * pParentWnd=0x00000000) MyApp.exe!CMyDlg::CMyDlg(CWnd * pParent=0x00000000) Running in the debugger, if I manually change pParentWnd back to 0 in CDialog::CreateIndirect, everything works fine... but how do I stop it happening in the first place?

  • Are there solutions for streamlining the update of legacy code in multiple places?

    - by ccomet
    I'm working in some old code which was originally designed for handling two different kinds of files. I was recently tasked with adding a new kind of file to this code. Most of my problems were solved by filling out an extensive XML file with a new entry that handled everything from what lists were named to how the file is written in plural lower case. But this ended up being insufficient, as there were maybe 50 different places in 24 different code files where I had to update hardcoded switch-statements that only branched for the original two file types. Unfortunately there is no consistency in this; there are methods which operate half from the XML file, and half off of hardcode. Some of the files which look like they would operate off of the XML file don't, and some that I would expect that I'd need to update the hardcode don't need it. So the only way to find the majority of these is to run through testing the whole system when only part of it is operational, finding that one step to fix (when I'm lucky that error logging actually tells me what is going on), and then running the whole thing again. This wastes time testing the parts of the code which are already confirmed to work, time better spent testing the new parts I have to add on top of it all. It's a hassle and a half, and to my luck I can expect that I will have to add yet another new kind of file in the near future. Are there any solutions out there which can aid in this kind of endeavour? Something which I can input some parameters of current features, document what points in a whole code project actually need to be updated, and run something nice the next time I need to add a new feature to the code. It needn't even be fully automated, something that'll help me navigate straight to the specific points in everything and maybe even record what kind of parameters need to be loaded. Doubt it matters specifically, but the code is comprised of ASP.NET pages, some ASP.NET controls, hundreds of C# code files, and a handful of additional XML files. It's all currently in a couple big Visual Studio 2008 projects.

  • How do I find multiple matches with one regular expression?

    - by christian studer
    I've got the following string: response: id="1" message="whatever" attribute="none" world="hello" The order of the attributes is random. There might be any number of other attributes. Is there a way to get the id, message and world attribute in one regular expression instead of applying the following three one after another? / message="(.*?)"/ / world="(.*?)"/ / id="(.*?)"/

  • How to apply or chain multiple matching templates in XSLT?

    - by Ignatius
    I am working on a stylesheet employing many templates with match attributes: <xsl:template match="//one" priority="0.7"> <xsl:param name="input" select="."/> <xsl:value-of select="util:uppercase($input)"/> <xsl:next-match /> </xsl:template> <xsl:template match="/stuff/one"> <xsl:param name="input" select="."/> <xsl:value-of select="util:add-period($input)"/> </xsl:template> <xsl:function name="util:uppercase"> <xsl:param name="input"/> <xsl:value-of select="upper-case($input)"/> </xsl:function> <xsl:function name="util:add-period"> <xsl:param name="input"/> <xsl:value-of select="concat($input,'.')"/> </xsl:function> What I would like to do is be able to 'chain' the two functions above, so that an input of 'string' would be rendered in the output as 'STRING.' (with the period.) I would like to do this in such a way that doesn't require knowledge of other templates in any other template. So, for instance, I would like to be able to add a "util:add-colon" method without having to open up the hood and monkey with the existing templates. I was playing around with the <xsl:next-match/> instruction to accomplish this. Adding it to the first template above does of course invoke both util:uppercase and util:add-period, but the output is an aggregation of each template output (i.e. 'STRINGstring.') It seems like there should be an elegant way to chain any number of templates together using something like <xsl:next-match/>, but have the output of each template feed the input of the next one in the chain. Am I overlooking something obvious?

  • How to transfer binary data through multiple http server?

    - by solotim
    Well, the question is not intended to be that big. Let me explain the scenario: I have two http servers. server A is accessible to end user by web browser, while server B is internal server which can only be accessed by server A. If server B generate some big jpeg image in local disk, obviously we can't just delivery those path to image to server A and eventually to end user. Then, how to let end user see those image without firstly storing those image data in server A temporarily? I run PHP on server A and perl on server B, but this should not matter. I need a general pattern for implementing this.

  • Should I be concerned about performance with connections to multiple databases?

    - by Josh Ryan
    I have a PHP app that is running on an Apache server with MySQL databases. Based on the subdomain that users access, I am connecting them to a database (sub1.domain.com connects to database_sub1 and sub2.domain.com connects to database_sub2). Right now there are 10 subdomain-database combos, but that number could potentially grow to well over 100. So, is this a bad thing? Considering my situation, is myslq_pconnect a better way to go? Thanks, and please let me know if more info would be helpful. Josh

  • how to setup rails Authenticity Token to work with multiple domains?

    - by bwizzy
    I'm building an app that uses subdomains as account handles (myaccount.domain.com) and I have my sessions configured to work across the sub-domains like so: config.action_controller.session = {:domain => '.domain.com'} In addition to the subdomain a user can input a real domain name when they are creating their account. My Nginx config is setup to watch for *.com *.net etc, and this is working to serve out the pages. The problem comes when a site visitor submits a comment form on a custom domain that was input by the user. The code is throwing an "Invalid AuthenticityToken" exception. I'm 99% sure this is because the domain the user is on isn't specified as the domain in the config.action_controller.session. Thus the authenticity token isn't getting matched up because Rails can't find their session. So, the question is: Can you set config.action_controller.session to more than 1 domain, and if so can you add / remove from that value at runtime without restarting the app?

  • How do I store multiple copies of the same field in Django?

    - by Alistair
    I'm storing OLAC metadata which describes linguistic resources. Many of the elements of the metadata are repeatable -- for example, a resource can have two languages, three authors and four dates associated with it. Is there any way of storing this in one model? It seems like overkill to define a model for each repeatable metadata element -- especially since the models will only have one field: it's value.

  • How can i tell jaxb / Maven to genereate multiple schema packages?

    - by M.R.
    Example: </plugin> <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.7.1</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <schemaDirectory>src/main/resources/dir1</schemaDirectory> <schemaIncludes> <include>schema1.xsd</include> </schemaIncludes> <generatePackage>schema1.package</generatePackage> </configuration> </plugin> <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <version>0.7.1</version> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <schemaDirectory>src/main/resources/dir2</schemaDirectory> <schemaIncludes> <include>schema2.xsd</include> </schemaIncludes> <generatePackage>schema2.package</generatePackage> </configuration> </plugin> </plugins> What happened: Maven executes the the first plugin. Then deletes the target folder and creates the second package, which then is visible. I tried to set target/somedir1 for the first configuration and target/somedir2 for the second configuration. But the behavior does not not change? Any ideas? I do not want to generate the packages directly in the src/main/java folder, because these packages are genereated and should not be mixed with manual created classes.

  • How do I configure multiple Ubuntu Python installations to avoid App Engine's SSL error?

    - by Linc
    I have Karmic Koala which has Python 2.6 installed by default. However I can't run any Python App Engine projects because they require Python 2.5 and python ssl. To install ssl I installed python2.5-dev first while following some instructions I found elsewhere. sudo apt-get install libssl-dev sudo apt-get install python-setuptools sudo apt-get install python2.5-dev sudo easy_install-2.5 pyopenssl However, I am afraid this is not good for my Ubuntu installation since Ubuntu expects to see version 2.6 of Python when you type 'python' on the command line. Instead, it says '2.5.5'. I tried to revert to the original default version of Python by doing this: sudo apt-get remove python2.5-dev But that didn't seem to do anything either - when I type 'python' on the command line it still say 2.5.5. And App Engine still doesn't work after all this. I continue to get an SSL-related error whenever I try to run my Python app: AttributeError: 'module' object has no attribute 'HTTPSHandler' UPDATE: Just checked whether SSL actually installed as a result of those commands by typing this: $ python2.5 Python 2.5.5 (r255:77872, Apr 29 2010, 23:59:20) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import ssl Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: No module named ssl >>> As you can see, SSL is still not installed, which explains the continuing App Engine error. If anyone knows how I can dig myself out of this hole, I would appreciate it.

  • How can I match end-of-line multiple times in a regex without interpolation?

    - by harschware
    Hi, if I have a input with new lines in it like: [INFO] xyz [INFO] How can I pull out the xyz part? I tried a pattern like /^\[INFO\]$(.*?)$\[INFO\]/ms, but perl gives me: Use of uninitialized value $\ in regexp compilation at scripts\t.pl line 6. I've been trying things to get interpolation to stop like using qr// but alas, no love. EDIT: The key is that the end-of-line anchor is a dollar sign but at times it may be necessary to intersperse the end-of-line anchor through the pattern. If the pattern is interpolating then you might get problems such as uninitialized $\. For instance an acceptable solution here is /^\[INFO\]\s*^(.*?)\s*^\[INFO\]/ms but that does not solve the crux of the first problem. I've changed the anchors to be ^ so there is no interpolation going on, and with this input I'm free to do that. But what about when I really do want to reference EOL with $ in my pattern? How do I get the regex to compile?

  • Form (or Formset?) to handle multiple table rows in Django

    - by Ben
    Hi, I'm working on my first Django application. In short, what it needs to do is to display a list of film titles, and allow users to give a rating (out of 10) to each film. I've been able to use the {{ form }} and {{ formset }} syntax in a template to produce a form which lets you rate one film at a time, which corresponds to one row in a MySQL table, but how do I produce a form that iterates over all the movie titles in the database and produces a form that lets you rate lots of them at once? At first, I thought this was what formsets were for, but I can't see any way to automatically iterate over the contents of a database table to produce items to go in the form, if you see what I mean. Currently, my views.py has this code: def survey(request): ScoreFormSet = formset_factory(ScoreForm) if request.method == 'POST': formset = ScoreFormSet(request.POST, request.FILES) if formset.is_valid(): return HttpResponseRedirect('/') else: formset = ScoreFormSet() return render_to_response('cf/survey.html', { 'formset':formset, }) And my survey.html has this: <form action="/survey/" method="POST"> <table> {{ formset }} </table> <input type = "submit" value = "Submit"> </form> Oh, and the definition of ScoreForm and Score from models.py are: class Score(models.Model): movie = models.ForeignKey(Movie) score = models.IntegerField() user = models.ForeignKey(User) class ScoreForm(ModelForm): class Meta: model = Score So, in case the above is not clear, what I'm aiming to produce is a form which has one row per movie, and each row shows a title, and has a box to allow the user to enter their score. If anyone can point me at the right sort of approach to this, I'd be most grateful. Thanks, Ben

  • How do I define a template class and divide it into multiple files?

  • dynamic grid style form that lets you update multiple rows in a single post in asp.net mvc

    - by Charlie Bear
    I'm starting out with MVC but not sure it's the best option. I need to create a form that is based upon a collection. Eg it might look like this: product Price Item 1 [textbox] Item 2 [textbox] [submit button] where "item" is pulled from the database and textbox allows users to update the price. essentially this is a type of datagrid but i don't want webforms style update each row one at a time i need to update the entire set of text boxes in one post. Ideally I don't want a javascript based solution as it has to work without javascript. Is this possible in MVC or should I stick to webforms (where I could do this in a repeater by iterating through he repeater items on postback)

  • Who calls the Destructor of the class when operator delete is used in multiple inheritance.

    - by dicaprio-leonard
    This question may sound too silly, however , I don't find concrete answer any where else. With little knowledge on how late binding works and virtual keyword used in inheritance. As in the code sample, when in case of inheritance where a base class pointer pointing to a derived class object created on heap and delete operator is used to deallocate the memory , the destructor of the of the derived and base will be called in order only when the base destructor is declared virtual function. Now my question is : 1) When the destructor of base is not virtual, why the problem of not calling derived dtor occur only when in case of using "delete" operator , why not in the case given below: derived drvd; base *bPtr; bPtr = &drvd; //DTOR called in proper order when goes out of scope. 2) When "delete" operator is used, who is reponsible to call the destructor of the class? The operator delete will have an implementation to call the DTOR ? or complier writes some extra stuff ? If the operator has the implementation then how does it looks like , [I need sample code how this would have been implemented]. 3) If virtual keyword is used in this example, how does operator delete now know which DTOR to call? Fundamentaly i want to know who calls the dtor of the class when delete is used. Sample Code class base { public: base() { cout<<"Base CTOR called"<<endl; } virtual ~base() { cout<<"Base DTOR called"<<endl; } }; class derived:public base { public: derived() { cout<<"Derived CTOR called"<<endl; } ~derived() { cout<<"Derived DTOR called"<<endl; } }; I'm not sure if this is a duplicate, I couldn't find in search. int main() { base *bPtr = new derived(); delete bPtr;// only when you explicitly try to delete an object return 0; }
