  • .NET Regular Expressions - Shorter match

    - by Xavier
    Hi Guys, I have a question regarding .NET regular expressions and how it defines matches. I am writing: var regex = new Regex("<tr><td>1</td><td>(.+)</td><td>(.+)</td>"); if (regex.IsMatch(str)) { var groups = regex.Match(str).Groups; var matches = new List<string>(); for (int i = 1; i < groups.Count; i++) matches.Add(groups[i].Value); return matches; } What I want is get the content of the two following tags. Instead it returns: [0]: Cell 1</td><td>Cell 2</td>... [1]: Last row of the table Why is the first match taking </td> and the rest of the string instead of stopping at </td>?

  • why selenium.isConfirmationPresent() returns true after using chooseCancelOnNextConfirmation

    - by padmakumar
    I am having a code like the following selenium.chooseCancelOnNextConfirmation(); selenium.click("deleteRequest");// confirm dialog will be displayed on clicking the button System.out.println("is confirmation present "+selenium.isConfirmationPresent()); Eventhough i am using selenium.chooseCancelOnNextConfirmation(), please let me know why selenium.isConfirmationPresent() returns true. But selenium.isConfirmationPresent() returns false after selenium.getConfirmation(); Is it mandatory to use selenium.getConfirmation(), as i am not able to do further processing. It says com.thoughtworks.selenium.SeleniumException: ERROR: There was an unexpected Confirmation! [Are you sure to delete selected request(s)?] com.thoughtworks.selenium.HttpCommandProcessor.throwAssertionFailureExceptionOrError(HttpCommandProcessor.java:97) at com.thoughtworks.selenium.HttpCommandProcessor.doCommand(HttpCommandProcessor.java:9

  • User interface for addition/deletion of items to a list?

    - by agentcris
    I have a ban list that I'm building as part of an application that displays articles. This ban list will contain keywords, which if found in an article, would lead to the article disabled(the article will not be displayed on the front-end) I'm having a tough time visualizing the UI. I could always display a textarea and ask the user to enter keywords comma separated and when they want to delete again the textarea will be presented and they can edit the entered keywords. But I find my idea very unfriendly to the user. My question is how do I program the UI so that its easy to add new keywords. I also would like to be adviced on a nifty way showing the existing keywords and also deleting them. This ban list will be part of the admin panel/backend and will be accessible only to the site administrator.

  • Text in gtk.ComboBox without active item

    - by Yotam
    The following PyGTk code, gives a combo-box without an active item. This serves a case where we do not want to have a default, and force the user to select. Still, is there a way to have the empty combo-bar show something like: "Select an item..." without adding a dummy item? import gtk import sys say = sys.stdout.write def cb_changed(w): say("Active index=%d\n" % w.get_active()) topwin = gtk.Window() topwin.set_title("No Default") topwin.set_size_request(0x100, 0x20) topwin.connect('delete-event', gtk.main_quit) vbox = gtk.VBox() ls = gtk.ListStore(str, str) combo = gtk.ComboBox(ls) cell = gtk.CellRendererText() combo.pack_start(cell) combo.add_attribute(cell, 'text', 0) combo.connect('changed', cb_changed) ls.clear() map(lambda i: ls.append(["Item-%d" % i, "Id%d" % i]), range(3)) vbox.pack_start(combo, padding=2) topwin.add(vbox) topwin.show_all() gtk.main() say("%s Exiting\n" % sys.argv[0]) sys.exit(0)

  • More HTTP verbs with AS3?

    - by tedw4rd
    I'm developing a social game in Flash with a team of developers. Our server-side guy has developed a really slick RESTful API for the Flash client to talk to. A lot of the client-server interactions involve adding and removing objects from a persistent world, so the API makes extensive use of the PUT and DELETE verbs. The problem is, the URLRequest object in AS3 only supports the GET and POST verbs. We're on a strict schedule, and we'd really rather not have to rewrite the whole API to just use GET and POST. Has anyone come up with a good way to get Flash to send other verbs?

  • Heap Error in C++

    - by BobAlmond
    Dear all, I'm a beginner programmer in C++. Recently, I'm working on image processing thing using C++. but I have some problem that I want to ask.

Is there anything wrong with that code, I mean, can I allocate memory and release it in the same loop? Thanks in advance...

  • I need a very simple PHP database front-end admin panel; a simple records editor for a specified tab

    - by Lansen Q
    Hi there, I am looking to add some dynamics to our corporate website. This is a secondary role so I'd rather not be spending a ton of time on it. At this point, all I need is a simple PHP script where a non-technical user can pull up and manage the records in a MySQL table. There's only one table of data to be managed; it's just that it will be accessed and updated quite frequently. I recall that Grails' default scaffolding feature has precisely this: list of entries with the ability to add, edit and delete, with no nonsense. What would be the best tool to use for this? I would rather not be writing it from scratch, as this will take me quite some time. It seems like the kind of thing that ought to exist somewhere. Thanks!

  • Returning objects with dynamic memory

    - by Caulibrot
    I'm having trouble figuring out a way to return an object (declared locally within the function) which has dynamic memory attached to it. The problem is the destructor, which runs and deletes the dynamic memory when the object goes out of scope, i.e. when I return it and want to use the data in the memory that has been deleted! I'm doing this for an overloaded addition operator. I'm trying to do something like: MyObj operator+( const MyObj& x, const MyObj& y ) { MyObj z; // code to add x and y and store in dynamic memory of z return z; } My destructor is simply: MyObj::~MyObj() { delete [] ptr; } Any suggestions would be much appreciated!

  • Rails creating and updating 2 model records simultaneously

    - by LearnRails
    I have 2 tables product and history product table id name type price location 1 abc electronics $200 aisle1 history table id product_id status 1 1 price changed from $200 to $180 Whenever the product price or location is updated by a user by hitting the update button, 1) the changes should be automatically be reflected in the history status column without the user having to enter that manually. if the price is updated from 200 to 180 then a new history row will be created with new id and the status column will say ' price changed from $200 to $180' if the location is updated from aisle1 to aisle 2 then status displays ' loc changed from ailse1 to aisle 2' I tried to @product = Product.new(params[:product]) @history= History.new(params[:history]) if @product.save @history.new(attributes) == I am not sure of whether this approach is correct I would really appreciate if someone could tell me how the history can be automatically updated in this case.

    - by Dodi300

  • .BAT Switches Parsing

    - by giiYanJ
    Erm.. I'm working with a switches parsing in BAT files, which goes like this: <commands> -a -b -x -y -z -u abc ...... The user may input a lot of switch, or none. So I used looped shift to make parsing infinite switches possible: :loop IF "%1"=="-a" ... SHIFT GOTO loop But when the script ends, I always get cmd executing the switches and showing up error like '-n' is not recognized as an internal... So, someone got any idea? Thanks a lot... P/S: Make solution sticks with BAT script if possible as using other language may cause dependencies problem as this script is aimed on ANY computer with Windows. Finally, thanks again =) EDIT: Tried shf301 suggestion, i found out that I used DEL %0 to delete itself but it seems the %0 is shifted into the arguments because of the SHIFT command.

  • SqlAlchemy hangs after adding record in MS SQL

    - by Patrick
    I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?

  • Singelton restricted to instance of dll

    - by codeySmurf
    If I create a singleton class in the context of a dll, the singleton class is instantiated once and used by all instances of the dll. I am using a dll as a plug-in for an application. Now the following thing came to my mind: If I use a singleton Class, it will be shared across multiple instances of the plug-in. However, this makes it difficult to manage the lifetime of the singleton class efficiently. The only way I could think of would be to use a reference count and to make the singleton delete its self when the reference count is 0. Does anyone have any better ideas on that? Is there any good way to restrict the singleton object to one instance of the dll? Language is c++

  • Dump Hibernate activity to sql script file

    - by zeven
    Hi, I'm trying to log hibernate activity (only dml operations) to an sql script file. My goal is to have a way to reconstruct the database from a given starting point to the current state by executing the generated script. I can get the sql queries from log4j logs but they have more information than the raw sql queries and i would need to parse them and extract only the helpful statements. So i'm looking for a programatic way, maybe by listening the persist/merge/delete operations and accessing the hibernate-generated sql statements. I don't like to reinvent the wheel so, if anybody know a way for doing this i would appreciate it very much. Thanks in advance

  • C++: Question about freeing memory

    - by Martijn Courteaux
    On Learn C++, they wrote this to free memory: int *pnValue = new int; // dynamically allocate an integer *pnValue = 7; // assign 7 to this integer delete pnValue; pnValue = 0; My question is: "Is the last statement needed to free the memory correctly, completly?" I thought that the pointer *pnValue was still on the stack and new doesn't make any sense to the pointer. And if it is on the stack it will be cleaned up when the application leaves the scope (where the pointer is declared in), isn't it?

  • Change find() type of contained model or array transformation

    - by Ramon Marco Navarro
    I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

  • How to remove strings of certain lengths

    - by Macosx Iam
    So I have this array, and I want to delete strings that are 2 or 4 characters in length (strings that contain 2 or 4 characters). I am doing this method, and it doesn't work, even though logically, it SHOULD work. public static void main(String[] args) { ArrayList<String> list = new ArrayList<String>(); list.add("This"); list.add("is"); list.add("a"); list.add("test"); for (int i=0; i<list.size(); i++) { if(list.get(i).length()==2 || list.get(i).length()==4) { list.remove(i); } } } I'd like to stick to this method of doing it. Can you please give me some suggestions as to how to correct this code? The output of this code when I run it is: [is, a] Even though I want the output to be [a] because "is" is 2 characters long.

  • Am I underestimating MySQL ?

    - by user281434
    Hi I'm about to implement a feature on my website that recommends content to users based on the content they already have in their library (a la Last.fm). A single table holds all the records of the content they have added, so a row might look something like: -------------------- | userid | content | -------------------- | 28 | a | -------------------- When I want to recommend some content for a user, I use a query to get all the user id's that have content a added in their library. Then, out of those user id's, I make another query that finds the next most common content among those users (fx. 'b'), and show that to the user. My problem is when I'm thinking about the big picture here. Say that eventually my site will hold something like 500.000 rows in the table, will this make the MySQL response very slow or am I underestimating MySQL here?

  • How to handle un-assigned records

    - by Mico
    I have this PHP page where the user can select and un-select items. The interface looks like this: Now I'm using these code, when the user hit the save changes button: foreach( $value as $al_id ){ //al_id is actually location id //check if a record exists //if location were assigned and leave it as is $assigned_count = $this->AssignedLoc->checkIfAssigned( $tab_user_id, $al_id ); if( $assigned_count == 0 ){ //else if not, insert this new record $this->insertAssigned( $tab_user_id, $company_id, $al_id ); } } Now my question is, how do I delete the un assigned locations? For example in the screenshot above, there are 4 assigned locations, if I'm gonna remove (or unassign) "Mercury Morong" and "GP Hagonoy" from the assigned locations, only two must remain. What are the possible solutions using PHP? Thanks for any help!

  • Flash CS4/AS3 Writing local file from local game without save dialog prompt?

    - by dragonridingsorceress
    I'm writing a game to be run locally, on the user's computer. NOT over the internet. I want to have a file that will hold the usernames and avatar indices (they're in an array). I want to know if there's a way to write to files through Flash with AS3. I'm using CS4. I'd also like to know if you can delete files through Flash, though that's just optional. Thanks in advance for any help you can give.

  • Implement abstract class as a local class? pros and cons

    - by sinec
    Hi, for some reason I'm thinking on implementing interface within a some function(method) as local class. Consider following: class A{ public: virtual void MethodToOverride() = 0; }; A * GetPtrToAImplementation(){ class B : public A { public: B(){} ~B(){} void MethodToOverride() { //do something } }; return static_cast<A *>(new B()); } int _tmain(int argc, _TCHAR* argv[]) { A * aInst = GetPtrToAImplementation(); aInst->MethodToOverride(); delete aInst; return 0; } the reason why I'm doing this are: I'm lazy to implement class (B) in separate files MethodToOverride just delegates call to other class Class B shouldn't be visible to other users no need to worry about deleting aInst since smart pointers are used in real implementation So my question is if I'm doing this right? Thanks in advance!
