• What's the fastest way to strip and replace a document of high unicode characters using Python?

  - by Rhubarb

  I am looking to replace from a large document all high unicode characters, such as accented Es, left and right quotes, etc., with "normal" counterparts in the low range, such as a regular 'E', and straight quotes. I need to perform this on a very large document rather often. I see an example of this in what I think might be perl here: http://www.designmeme.com/mtplugins/lowdown.txt Is there a fast way of doing this in Python without using s.replace(...).replace(...).replace(...)...? I've tried this on just a few characters to replace and the document stripping became really slow.

• IWebBrowser2: how to force links to open in new window?

  - by Rob McAfee

  The MSDN documentation on WebBrowser Customization explains how to prevent new windows from being opened and how to cancel navigation. In my case, my application is hosting an IWebBrowser2 but I don't want the user to navigate to new pages within my app. Instead, I'd like to open all links in a new IE window. The desired behavior is: user clicks a link, and a new window opens with that URL. A similar question was asked and answered here and rather than pollute that answered post, it was suggested I open a new discussion. The members on the related post suggested I should be able to do this by trapping DISPID_BEFORENAVIGATE2, setting the cancel flag, and writing code to open a new window, but I've found out that the browser control gets lots of BeforeNavigate2 events that seem to be initiated by scripts on the main page. For example, amazon.com fires BeforeNavigate2 events like crazy, and they are not a result of link invocation. Replies appreciated!

• Reading from the HTML DOM returns UTF-8 characters

  - by teehoo

  I have a contenteditable div where I'm reading individual characters and sending them off to a server (for more background this is similar to Google Wave where typing a character automatically sends it) I was using a plain old html textfield before and everything worked fine until I "upgraded" to a contenteditable div. My problem is that now the characters are in UTF-8 format, which is causing some weird problems on the server that I would rather not debug. It would be much easier to force everything to be ASCII on the client side. Is there any way to do this? I tried putting in a meta tag stating the html file is charset=ISO-8859-1, but it doesnt seem to work. Reading from the div tag still returns UTF-8 codes. (One example is when I press space I get the pair 0xC2 0xA0 which corresponds to a "non-breaking white space"

• Ruby on Rails: How best to escape a string in a model?

  - by williamjones

  I want my application to sanitize html on input rather than on display, so that the fields saved into the database are sanitized. I've been doing this with strip_tags, and it was working great. However, this has the downside that it means the user can't input anything that's bracketed with < and . How can I tell Rails in the model to securely escape tags before saving them to the database? I'd like to not have to call h on the sanitized fields again before using them in the views.

• Linux based MS Office thumbnail generation

  - by El Yobo

  I've been taken on board to work on a PHP based web application. One part of the application generates thumbnail images for MS Office documents on demand, and it uses MS Office + the VeryPDF docprint utility to do this. Because of this one requirement, the system is running on Windows Server 2003 + IIS. I would prefer to have the system running on a Linux server, rather than MS, as I have far more experience in administering Linux systems than Windows and we have no other in-house technical staff. Does anyone know a way to handle the document conversion using native Linux software? I would love something PHP native, but am willing to look outside that if necessary. Thanks for your suggestions.

• Check if there are any repeated elements in an array recursively

  - by devoured elysium

  I have to find recursively if there is any repeated element in an integer array v. The method must have the following signature: boolean hasRepeatedElements(int[] v) I can't see any way of doing that recursively without having to define another method or at least another overload to this method (one that takes for example the element to go after or something). At first I thought about checking for the current v if there is some element equal to the first element, then creating a new array with L-1 elements etc but that seems rather inefficient. Is it the only way? Am I missing here something?

• Javascript Grid that can handle sections in a table

  - by user335410

  I am making an ASP.NET MVC application that lets a user design a questionnaire that other users can fill out. Now, questionnaires, rather than just having a list of questions, often have sections or subsections that could have headings and not the other columns that an ordinary row (a question) would have. I want a JS Grid that can handle sections and subsections elegantly. I tried using JQGrid, but there the options I have are limited to a "Grid as Subgrid" structure. The appearance becomes quite complex and unlike a questionnaire. Is there a Javascript Grid or a JQuery plugin that can handle this? I can write my own HTML table as long as the JS app will format the table and will add some user-friendliness to the table.

• Flex HDividedBox prevent dragging

  - by Jeremy Mitchell

  I'd love to be able to prevent dragging of a HDividedBox's divider based on a condition. for example: <mx:HDividedBox id="hd1" liveDragging="true" dividerDrag="dividerDragHandler(event)"> <Canvas id="c1"/> <Canvas id="c2"/> </HDividedBox> private function dividerDragHandler(event:DividerEvent):void { if (_something 10) { event.preventDefault(); } } Any ideas how I can do something like that? And I'd rather not mess with the widths of the child canvases. Thanks.

• Regexp look-behind to match internet speeds

  - by Sandman

  So the user may search for "10 mbit" after which I want to capture the "10" so I can use it in a speed-search rather than a string-search. This isn't a problem, the below regexp does this fine: if (preg_match("/(\d+)\smbit/", $string)){ ... } But, the user may search for something like "10/10 mbit" or "10-100 mbit". I don't want to match those with the above regexp - they should be handled in another fashion. So I would like a regexp that matches "10 mbit" if the number is all-numeric as a whole word (i.e. contained by whitespace, newline or lineend/linestart) Using lookbehind, I did this: if (preg_match("#(?<!/)(\d+)\s+mbit#i", $string)){ Just to catch those that doesn't have "/" before them, but this matched true for this string: "10/10 mbit" so I'm obviously doing something wrong here, but what?

• Making a jQuery plugin work on all objects

  - by Jon Winstanley

  I am using the jQuery physics plugin for a pet project I am working on. The plugin enables the moving of DOM objects in realistic ways using velocity, gravity, wind etc. However I want to use the plugin to calculate where objects are to be placed inside a canvas element, not DOM objects. How do I change the plugin script functions to work on any object with 'top' and 'left' properties rather than only working with DOM objects: Currently the script functions look like this: jQuery.fn.funname = function() { return this; };

• .NET Conditional Callback on a type.

  - by Mahesh

  I have a stock price which changes by nature all the time. And, there will be many users who wants to buy that stock. Let's say that the stock price is started at 10 and let's say, 30 people bid for 10.98, 20 people bid for 7.45, 100 people bid for 8.99. During the day, the stock price can touch any of these values, and if that happens, I want to execute all the orders for users who quoted that price. Technically, I am storing in a List. Whenever the price changes, I am checking against all the values in the list and executing those that satisfy the quoted price. Class Bids { string stockname; double quote; } Is there any better alternative way to callback the satisfied items in the list rather than checking all the items whenever there is a change?? If storing in a list is not right way of doing it, let me know the best way.

• Explain DLL Dependencies to a lay person

  - by wheaties

  This follows from a previous posting I made about lack of a clean test machine for software installations. I'm doing a bad job of explaining how DLL dependencies work and how some machines might not have the right libraries at the time of installation. The problem is that it's being viewed as a defect with the build process. I'm trying to educate the higher ups that it's not the build process per se but rather the installation process which is to blame. Here's a quote from my boss relating subcontractor work to our work to put it into perspective: I'm not a software person. All I see is that when they hand something to us it just works but when we hand something to the client there's all sorts of problems. There must be something wrong with how you're building the code. It's very easy to see how someone who is smart (scarily smart) could come to the wrong conclusion. So how would you explain the whole DLL dependency issue?

• Verifying serialisation streams when used for messaging

  - by Nick

  I want to add distributed messaging to some applications. One target would be embedded and the other applications would be running on Windows. I'm thinking of having a connection manager, to which all of the applications would connect and communicate. I only need some simple kind of RPC mechanism. I've looked at Google Protocol Buffers, but I don't really like the idea of code generation. I'd rather use serialisation and somehow verify the format of the serialised stream. I.e. Perhaps send metadata about what the stream would contain so that each endpoint can verify it is reading the correct version. Does anyone know of any examples of this? Perhaps the message format could be read from a file which all the applications read to verify the stream format?

• JavaScript array to PHP array then process in PHP and return

  Example: javascript: var mycourses=new Array(); mycourses[0]="History"; mycourses[1]="Math"; mycourses[1][0]="Introduction to math"; mycourses[1][1]="Math 2"; mycourses[1][2]="Math 3"; PHP will then run these values through functions (please note values are mostly not strings as in the example above but rather numbers), the functions will return some text which will than be displayed in a form How should I go about doing this? p.s.: I found some similar stuff, but nothing quite like this... as far as I see I will have to use JSON (is there a way to code it from JS automatically - saw this for strings) and AJAX

• How Do I Pass The Value (Not The Reference) of a JS Variable to a Function?

  - by ryan

  Here is a simplified version of something I'm trying to run: for (var i = 0; i < results.length; i++) { marker = results[i]; google.maps.event.addListener(marker, 'click', function() { change_selection(i); }); } but I'm finding that every listener uses the value of results.length (the value when the for loop terminates). How can I add listeners such that each uses the value of i at the time I add it, rather than the reference to i?

• swing: event listener support class

  - by Jason S

  Is there any preexisting class that helps support add/remove EventListener operations? (kind of like PropertyChangeSupport) I'm trying to partition my code into a model and view in Java. I have some data that arrives erratically, and would like the model to support some kind of EventListener so that a view can subscribe to changes in the model. The data is numerous + complicated enough that I don't want to have to do the whole fine-grained Javabeans property change support; rather I would just like to allow notification that the model has changed in a coarse way. how can I best do this?

• C# convert integer to hex and back again

  - by codette

  How can I convert the following? 2934 (integer) to B76 (hex) Let me explain what I am trying to do. I have User IDs in my database that are stored as integers. Rather than having users reference their IDs I want to let them use the hex value. The main reason is because it's shorter. So not only do I need to go from integer to hex but I also need to go from hex to integer. Is there an easy way to do this in C#?

• Is this __import__ functionality correct?

  - by Jason Baker

  I have a package named jiva_tasks, which I'm trying to import via celery (using the CELERY_IMPORTS attribute of celeryconfig. The import statement that celery is using is this: __import__(module, [], [], ['']) Oddly enough, when this syntax is used, the module gets imported twice, once as jiva_tasks and another time as jiva_tasks. (with a period at the end). Now, chances are good that celery should be passing in globals rather than an empty list, but this seems broken to me. It seems odd that even if given the wrong arguments, __import__ would import something that isn't a valid python module name. I know that the way to fix this is to pass in globals, but I want to understand why I'm getting this result. Is this a bug, or is there something I don't understand about how __import__ is working? Update: It also seems to be working fine if I use importlib.

• Float over two elements

  - by eWolf

  My problem is rather complex to explain, so I'll show you an example: http://ewolf.bplaced.de/misc/float.htm I want to have a floated element (the blue box) to be be placed over two other elements (red and green) and I want the whole thing to be fixed-width and centered (done by the box with the black border) while the background of the red and green box should fill the whole width. I'm actually not quite sure if the way I've done it now is XHTML/CSS valid, but it works - at least in Firefox. In IE6, the green box expands to fit the whole blue box - how can I fix this in IE6 or find another solution to show it correctly in all browsers?

• Eliminating static properties - What patterns do I have at my disposal?

  - by Jamie Dixon

  I currently have a type that I inject into my controllers that's used for getting and setting session data. I use this so that I can obtain relevant session information as _sessionData.Username rather than using Session["username"]. I'd like to use this session information across all of my views and would previously have done this by making the SessionData members static instead of injecting the SessionData class into my controller. I want to avoid using static members as well as having to pass the object to the view in each controller. What patterns best suit this type of scenario? What do you do to solve this same problem?

• RAII: Initializing data member in const method

  - by Thomas Matthews

  In RAII, resources are not initialized until they are accessed. However, many access methods are declared constant. I need to call a mutable (non-const) function to initialize a data member. Example: Loading from a data base struct MyClass { int get_value(void) const; private: void load_from_database(void); // Loads the data member from database. int m_value; }; int MyClass :: get_value(void) const { static bool value_initialized(false); if (!value_initialized) { // The compiler complains about this call because // the method is non-const and called from a const // method. load_from_database(); } return m_value; } My primitive solution is to declare the data member as mutable. I would rather not do this, because it suggests that other methods can change the member. How would I cast the load_from_database() statement to get rid of the compiler errors?
