• using html text in as3

  - by vincent

  Hello, i'm having a bit of a question, I have some newspost from my database. But there are tags in it and some tags aswell. My questiion is how i should go about it to get the newspost showing as it should be. The images should get shown instead of the tags etc. I know i'll have to work with a loader to use the images but how would as3 recognize them? Is there anyway i could use htmltext or something so as3 knows automaticly where the imagetags are? Also, if i add the image would it be possible to wrap the text around it? So i dont have an empty space next to the image?

• Web Application - Authentication / Login Framework

  - by user456563

  This is a very simple, probably a most asked question and frequently developed as part of any web application. Say I'm planning to build a web application and some of the functional requirements include (apart from the usual hard hitting security reqs), - Need to have users sign up for a new account profile - Authenticate user using the native app authentication / Facebook or Google or Yahoo or OpenId login - Allow lost password retrieval - Session handling needs Is there an out of the box frameworks (Drupal, Liferay??) that I can use to wrap my application which can be a bunch of JSP's or HTML's with JS? I know I'm asking a very simple and maybe a naive question. But this is a topic every web developer guru will go thru. Any help, advise and pointers much appreciated.

• How To Alter This Code So That It Only Redirects If There Is No Mouse Movement

  - by user1426261

  I have the following java script which redirects the user to another website (google in this case). <script type="text/JavaScript"> window.setTimeout("location=('http://www.google.com');",5000); </script> However, although i want the website to redirect to another website, i dont want it to redirect for no reason. My aim is for the website to redirect automatically on the condition that the cursor hasnt been moved for a little while. is this possible?

• MySQL: How to consume/discard the result of a query?

  - by GetFree

  I have a stored procedure which executes an optimize table statement for every table in a DB. Those optimize table statements are prepared statements of course (they have to be built at runtime) and I need to call that procedure from PHP using ext/mysql API. Unfortunately, ext/mysql does't support doing such thing because optimize table returns a result set and in order to handle that, the new mysql protocol is required, which is supported by the "new" ext/mysqli API. Well... there are several things I dont have control over, so it's not in my posibilities to upgrade to ext/mysqli any time soon, nor can I implement the procedure as PHP code rather than sql code. So I thought if it would be possible somehow to consume/discard the result of optimize table inside the stored procedure so that ext/mysql doesn't complain about it. One thing to consider is that since the optimize table statements are prepared statements, you can't use a cursor over them.

• How can I tell if an ADODB::_RecordsetPtr has already been created?

  - by scottm

  I am trying to write a class that uses ADO to retrieve SQL records. The intent is for the class to maintain one private recordset an other methods move forward, retrieve fields, etc. This is a basic example of my class: class SqlADO { private: ADODB::_RecordsetPtr m_recordset; public: void Open(); //open the connection void Execute(const char* sql); // creates or replaces current recordset void Next(); //moves recordset cursor forward void Field(const char* fieldName); //retrieves field name from current record of the recordset }; My Questions: In the Execute method, how can I check to see that the recordset instance has been created (or do I need to) so that I can close it first? Do you know of any good ADO COM Interop references?

• WPF: Bind DataGrid to List<String>

  - by Sam

  Funny, how sometimes the simple things bite me in the behind. I can bind a DataGrid nicely to a Collection of some arbitrary class, using a DataGridTextColumn like this: <DataGridTextColumn Header="Name" Binding="{Binding Name}"/> Now I want to bind a DataGrid to a simple Collection. So since there is no property "Name" or something like that to bind to, how do I write the binding: <DataGridTextColumn Header="Name" Binding="{Binding ???}"/> String has no Property "Value" or something like that. And if I just write {Binding } I'll end up with a one-way-binding, unable to write changes back to the Collection. Thinking about it, I think it is not possible to bind to a collection, so I do need to wrap my string into a class? Or is there a way?

• Can a function defined in a bookmarklet be called from a page-level script?

  - by Soviut

  I have a bookmarklet that needs to open a new window/tab. In order to avoid the popup blocker, I need to call the window.open() method directly in the bookmarklet ie: at the browser-level. However, I want to keep the bookmarklet updatable by loading external Javascript files. To do this, the bookmarklet needs to append script nodes to the DOM. If i were to put window.open() code in one of these externally loaded scripts, the popup blocker would block it since its page-level. What I want to know is if I can create a wrapper function around window.open() in my bookmarklet, then call it from the externally loaded script? What is the scope and what are the permissions on a wrap such as this?

• Using Linq, how to separate a list in to grouped objects by name?

  - by Dr. Zim

  I have a table where a record looks like this varchar(255) Name varchar(255) Text varchar(255) Value Name is the DDL name, Text is what is displayed, and Value is returned upon selection. There are between one and twenty options for each Name. Without iterating though each option like a cursor, is there any way to pull out a list of objects, one for each unique DDL Name, using Linq and C#? A sample of the data: Beds '4 (10)' 4 Beds '5 (1)' 5 Beds '7 (1)' 7 Baths 'NA (13)' NULL Baths '0 (1)' 0 Baths '1 (13)' 1 I was thinking about doing an outer select to get the unique Names, then an inner select to get the list of options for it, then return the set as a List of a set of Lists.

• Mimic Sublime Text multiselect in Notepad++ using autohotkey

  - by capnhud

  In sublime text 2 you can multi select(cursor) lines by holding ctrl+alt+arrow key (up/down). In notepad++ you can accomplish the same thing by holding ctrl and clicking the additional lines(areas) you would like to edit. I figured I could use a autohotkey script to accomplish the same functionality. So I tried #IfWinActive, ahk_class Notepad++ ^!Down::^Click but each time that I try to load the script I get Error at Line 2 Line Text: ^Click Error: This line does not contain a recognized action the program will exit then I tried #IfWinActive, ahk_class Notepad++ ^!Down::send ^Click but that shows up as ETXClick in notepad++ What more do I need to get this script to work only for Notepad++

• jQuery.Form wont submit

  - by kim

  Im´trying to submit a form without refreshing the page, but I´m having a problem. When I click submit the page refreshes and anothing gets posted. Here is the code, what am I doing wrong? (I´m a newbie) jQuery 1.4.2 and the jQuery Form Plugin 2.43 is present. tnx $(document).ready(function() { var options = { target: '#output2', url: https://graph.facebook.com/<%=fbUid%>/feed, type: post, clearForm: true // clear all form fields after successful submit //dataType: null // 'xml', 'script', or 'json' (expected server response type) //resetForm: true // reset the form after successful submit // $.ajax options can be used here too, for example: //timeout: 3000 }; // bind to the form's submit event $('#fbPostStatus').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); });

• Anonymous iterator blocks in Clojure?

  - by Checkers

  I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of anonymous iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

• JQuery - How to convert html with br's in it to html with p's in it?

  - by Spines

  On the my page I have html like this: hi<br>bye<br>sigh<br>hello <em>tie</em><br>lie with jquery, how can I convert it to html like this (basically using p's instead of br's): <p>hi</p><p>bye</p><p>sigh</p><p>hello <em>tie</em></p><p>lie</p> My first attempt at doing this was this code: $(container).contents().filter(function() { var val = this.nodeValue; return this.nodeType == TEXT_NODE && $.trim(val).length > 0; }) .wrap('<p></p>') .end() .filter('br') .remove(); This worked for the most part, except that it would put hello and <em>tie</em> in separate p elements. Does anyone know how I can do this properly?

• Scrolling through list element causes text elements to scroll as well

  - by DMK

  I'm using a list element with variableRowHeight and word-wrap set to true like in the example below: http://blog.flexexamples.com/2007/10/27/creating-multi-line-list-rows-with-variable-row-heights/ When I scroll through the list with a mouse scrollwheel the text in the listItems also scroll. I know that this is to do with the height of the textField... but I am unsure how to best resolve this issue. Any thoughts are appreciated! The issue that I am experiencing also occurs in the example above.

• How do would you use jQuery's .each() to apply the same script to each element with the same class?

  - by derekmx271

  I have a with multiple cart items listed. I have a "x-men logo" looking remove button that I want to fade-in next to the item when the customer hovers over a cart item. I had no issue getting this to work when there is only one item in the list. However, when there are multiple items in the cart, the jQuery operates funky. It still does the fade in, but only when I hover over the last item in the cart, and of course all of the "remove X" images become visible. Argh... So i searched around and think the .each() is my savior. I have been trying to get it to work, with no luck. My script just breaks when I attempt to implement it. Anyone have any pointers on this *.each() thing and how to implement it into my script?* I have tried putting a cartItem.each(function(){ around the mouseEnter/mouseLeave events (and used some $(this) selectors to make it "make sense") and that didn't do anything. Tried some other things as well with no luck... Here is the HTML (Sorry, there's a lot): <ul id="head-cart-items"> <!-- Item #1 --> <li> <!-- Item #1 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=AFE&amp;f=Air_Intakes_Magnum_FORCE_Stage-1_PRO_5R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/AFE/Intakes/Air_Intakes/Magnum_FORCE_Stage-1_PRO_5R/19029">AFE Magnum FORCE Stage-1 PRO 5R Air Intakes</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$195.00</span> <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> <!-- Item #2 --> <li> <!-- Item #2 Wrap --> <div class="head-cart-item"> <div class="head-cart-img" style='background-image:url("/viewimageresize.asp?mh=50&amp;mw=50&amp;p=Exedy&amp;f=Clutch_Kits_Carbon-R")'> </div> <div class="head-cart-desc"> <h3> <a href="/partdetails/Exedy/Clutch/Clutch_Kits/Carbon-R/19684">Exedy Carbon-R Clutch Kits</a> </h3> <span class="head-cart-qty">Qty: 1</span> <span class="head-cart-price">$2,880.00</span> <!-- Here is my other Remove-X... --> <a class="remove-x" href='/cart//7806888'> <img src="/images/misc/remove-x.png"> </a> </div> </div> </li> </ul> And here is the jQuery... $(document).ready(function(){ var removeX = $(".remove-x"); var cartItem = $(".head-cart-item"); // Start with an invisible X removeX.fadeTo(0,0); // When hovering over Cart Item cartItem.mouseenter(function(){ // Fade the X to 100% removeX.fadeTo("normal",1); // On mouseout, fade it back to 0% $(this).mouseleave(function(){ removeX.fadeTo("fast",0); }); }); }); If you didn't see it, here is the "X" I am trying to fade... <!-- Here is my Remove-X... --> <a class="remove-x" href='/cart//7806887'> <img src="/images/misc/remove-x.png"> </a> Thanks for the help in advance.

• hierarchical data from self referencing table in tree form

  - by Beta033

  It looks like this has been asked and answered in all the simple cases, excluding the one that I'm having trouble with. I've tried using a recursive CTE to generate this; however maybe a cursor would be better? Or maybe a set of recursive functions will do the trick? Can this be done in a cte? consider the following table PrimaryKey ParentKey 1 NULL 2 1 3 6 4 7 5 2 6 1 7 NULL should yield PK 1 -2 --5 -6 --3 7 -4 where the number of - marks equal the depth, my primary difficulty is the ordering.

• Java: Executing a Java application in a separate process

  - by _ande_turner_

  Can a Java application be loaded in a separate process using its name, as opposed to its location, in a platform independent manner? I know you can execute a program via ... Process process = Runtime.getRuntime().exec( COMMAND ); ... the main issue of this method is that such calls are then platform specific. Ideally, I'd wrap a method into something as simple as... EXECUTE.application( CLASS_TO_BE_EXECUTED ); ... and pass in the fully qualified name of an application class as CLASS_TO_BE_EXECUTED.

• How do I use a contact's photo in a table view cell?

  - by Andy

  I've got an app that has a table view that displays contact information in each row. I'd like to use the contact's stored image (if there is one available) as the image on the left-hand side of the cell. I've found some sketchy sample code in Apple's documentation, but the address book references some kind of weird data type (CFDataRef) that doesn't appear to correspond to the data types referenced in the table view programming guide (mainly UIImage). This seems like a pretty basic task, but I can't seem to wrap my head around it. Thanks in advance for any help you can offer.

• Regular Expression; Find whether a line contains any word with more than X characters.

  - by Simpsoid

  Hi, I am trying to use a Validator on a ASP.NET site and need to find whether the Street Address textbox contains a valid entry. Entries with words that are longer than X characters (in this case 25, with no punctuation or spaces) will cause the HTML on a printed A4 page to not wrap properly and therefore not to confrom to certain sizes correctly pushing the margins off. For a street address I want to match that something like "201 Long Road" is valid but "235 ReallyLongAndNarrowWindingRoadBesideTheRiver Street" is invalid. Using a Microsoft .Net Regular Expression Validator I need to know what the RegEx pattern might be. I think if it does find a match the Validator will fire correctly however if there is no match the Validator won't fire and the Update button (in this case) won't fire. Since Street addresses can contain Capital Letters and numbers etc. it will need to accomodate for that and also Spaces, Commas, Semi-Colons and Colons and Hyphens are valid characters too. Any help would be greatly appreciated as I am really stuck with this problem. Thanks, David

• In OCaml, how can I create an out_channel which writes to a string/buffer instead of a file on disk

  - by Tianyi Cui

  I have a function of type in_channel -> out_channel -> unit which will output something to an out_channel. Now I'd like to get its output as a string. Creating temporary files to write and read it back seems ugly, so how can I do that? Is there any other methods to create out_channel besides Pervasives.open_out family? Actually, this function implemented a repl. What I really need is to test it programmatically, so I'd like to first wrap it to a function of type string -> string. For creating the in_channel, it seems I can use Scanf.Scanning.from_string, but I don't know how to create the out_channel parameter.

• How to use AutoLayout to position UIButtons in horizontal lines?

  - by thomers

  I need to create a couple of UIButtons programmatically in my app (iOS 6.0 and above). Each button should have the optimal width to display button label text (of various lenghts). I want to display the buttons in a "wrap around" style: Starting from the left edge, each button should be positioned next to each other horizontally (in a defined order), and if a button does not fit in the current "line", it should start a new line on the left edge below the previous line. I could manually calculate the frame of each button in my code, but should I use AutoLayout (with programmatically creates NSLayoutConstraints) instead? How exactly would I need to set it up?

• How to go through every record in sqllite db?

  Hi guys. I think it's kinda easy one but still I'm new to android programming so please have patience. I want to know how can I get the number of records (rows) in a specific table in my db. I need this so I can create a loop to go through every record and add each one of it to the specific Array and display it later on. This is the source: db.openDataBase(); // open connection with db Cursor c = db.getTitle(5); // loop here through db, right now I'm fetching only one record startManagingCursor(c); //adding areas to the list here Area o1 = new Area(); o1.setOrderName(c.getString(1) + c.getString(2)); m_areas.add(o1); db.close(); Does anyone can help me with this please? Thx in advance!

• Best practices: displaying text that was input via multi-line text box

  - by chris

  I have a multi-line text box. When users simply type away, the text box wraps the text, and it's saved as a single line. It's also possible that users may enter line breaks, for example when entering a "bulleted" lists like: Here are some suggestions: - fix this - remove that - and another thing Now, the problem occurs when I try to display the value of this field. In order to preserve the formatting, I currently wrap the presentation in <pre> - this works to preserve user-supplied breaks, but when there's a lot of text saved as a single line, it displays the whole text block as single line, resulting in horizontal scrolling being needed to see everything. Is there a graceful way to handle both of these cases?

• Why does decorating a class break the descriptor protocol, thus preventing staticmethod objects from behaving as expected?

  - by Robru

  I need a little bit of help understanding the subtleties of the descriptor protocol in Python, as it relates specifically to the behavior of staticmethod objects. I'll start with a trivial example, and then iteratively expand it, examining it's behavior at each step: class Stub: @staticmethod def do_things(): """Call this like Stub.do_things(), with no arguments or instance.""" print "Doing things!" At this point, this behaves as expected, but what's going on here is a bit subtle: When you call Stub.do_things(), you are not invoking do_things directly. Instead, Stub.do_things refers to a staticmethod instance, which has wrapped the function we want up inside it's own descriptor protocol such that you are actually invoking staticmethod.__get__, which first returns the function that we want, and then gets called afterwards. >>> Stub <class __main__.Stub at 0x...> >>> Stub.do_things <function do_things at 0x...> >>> Stub.__dict__['do_things'] <staticmethod object at 0x...> >>> Stub.do_things() Doing things! So far so good. Next, I need to wrap the class in a decorator that will be used to customize class instantiation -- the decorator will determine whether to allow new instantiations or provide cached instances: def deco(cls): def factory(*args, **kwargs): # pretend there is some logic here determining # whether to make a new instance or not return cls(*args, **kwargs) return factory @deco class Stub: @staticmethod def do_things(): """Call this like Stub.do_things(), with no arguments or instance.""" print "Doing things!" Now, naturally this part as-is would be expected to break staticmethods, because the class is now hidden behind it's decorator, ie, Stub not a class at all, but an instance of factory that is able to produce instances of Stub when you call it. Indeed: >>> Stub <function factory at 0x...> >>> Stub.do_things Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'function' object has no attribute 'do_things' >>> Stub() <__main__.Stub instance at 0x...> >>> Stub().do_things <function do_things at 0x...> >>> Stub().do_things() Doing things! So far I understand what's happening here. My goal is to restore the ability for staticmethods to function as you would expect them to, even though the class is wrapped. As luck would have it, the Python stdlib includes something called functools, which provides some tools just for this purpose, ie, making functions behave more like other functions that they wrap. So I change my decorator to look like this: def deco(cls): @functools.wraps(cls) def factory(*args, **kwargs): # pretend there is some logic here determining # whether to make a new instance or not return cls(*args, **kwargs) return factory Now, things start to get interesting: >>> Stub <function Stub at 0x...> >>> Stub.do_things <staticmethod object at 0x...> >>> Stub.do_things() Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'staticmethod' object is not callable >>> Stub() <__main__.Stub instance at 0x...> >>> Stub().do_things <function do_things at 0x...> >>> Stub().do_things() Doing things! Wait.... what? functools copies the staticmethod over to the wrapping function, but it's not callable? Why not? What did I miss here? I was playing around with this for a bit and I actually came up with my own reimplementation of staticmethod that allows it to function in this situation, but I don't really understand why it was necessary or if this is even the best solution to this problem. Here's the complete example: class staticmethod(object): """Make @staticmethods play nice with decorated classes.""" def __init__(self, func): self.func = func def __call__(self, *args, **kwargs): """Provide the expected behavior inside decorated classes.""" return self.func(*args, **kwargs) def __get__(self, obj, objtype=None): """Re-implement the standard behavior for undecorated classes.""" return self.func def deco(cls): @functools.wraps(cls) def factory(*args, **kwargs): # pretend there is some logic here determining # whether to make a new instance or not return cls(*args, **kwargs) return factory @deco class Stub: @staticmethod def do_things(): """Call this like Stub.do_things(), with no arguments or instance.""" print "Doing things!" Indeed it works exactly as expected: >>> Stub <function Stub at 0x...> >>> Stub.do_things <__main__.staticmethod object at 0x...> >>> Stub.do_things() Doing things! >>> Stub() <__main__.Stub instance at 0x...> >>> Stub().do_things <function do_things at 0x...> >>> Stub().do_things() Doing things! What approach would you take to make a staticmethod behave as expected inside a decorated class? Is this the best way? Why doesn't the builtin staticmethod implement __call__ on it's own in order for this to just work without any fuss? Thanks.

• Creating a Dynamic calendar in Silverlight

  - by Tom

  I am attempting to create a long range calendar that dynamically loads (and unloads) event data as the user scrolls left or right through time. I'm really struggling to figure out how to lay the basic framework of the UI out and how to dynamically build the interface as the user scrolls by clicking and dragging the mouse in the view area. See the image below for a basic diagram of the intent. Each slice would have potentially multiple rectangles in it for events that occurred on that day (slice). I would like each slice to be a canvas to allow me to position those rectangles appropriately. There are a few problems that I am not yet sure how to tackle but this is the first big one that I've been mulling over for a while and can't quite wrap my head around: I know how to dynamically create controls but how would I go about adding things to one end of the scrollable content while removing things from the other depending on the way the user is scrolling? Any guidance in the right direction would be much appreciated! Thanks.
