• Using WPF class in a web application, problem with hosting permission

  - by tanathos

  I'm developing a DLL that uses WPF classes to make image manipulation. It works fine in my local environment, but when I try to use it in an hosted web site I retrieve this error: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed. exactly when I try to call the EndInit() of a BitmapImage object: BitmapImage originalImage = new BitmapImage(); originalImage.BeginInit(); originalImage.CacheOption = BitmapCacheOption.OnLoad; originalImage.UriSource = new Uri(physical_imagepath); originalImage.EndInit(); Any suggestion?

• get url:xml why external url does not work

  - by Kazim Cubbali

  I am trying to grab information from an external xml with the following code. It only worked when I uploaded same file to my servers. Why cant I grab information from an external url? <script language="javascript"> // This script uses jQuery to retrieve the news XML file and display the contents $(document).ready(function(){ $.ajax({ type: "GET", url: "www.simplyprofound.com/samples/xml_jquery/sample.xml", dataType: "xml", success: function(xml) { $(xml).find('item').each(function(){ var title = $(this).find('title').text(); var source = $(this).find('source').text(); var description = $(this).find('description').text(); $('<div class="news_title"></div>').html(title).appendTo('#news_wrap'); $('<div class="news_source"></div>').html(source).appendTo('#news_wrap'); $('<div class="news_description"></div>').html(description).appendTo('#news_wrap'); }); } }); }); </script>

• Best way to store weekly event in MySQL?

  - by mazin k.

  I have a table of weekly events that run on certain days of the week (e.g. MTWTh, MWF, etc.) and run on a certain time (e.g. 8am-5pm). What's the best way to store day of week information in MySQL to make retrieving and working with the data easiest? My CakePHP app is going to need to retrieve all events happening NOW(). For time of day, I would just use TIME. For days of the week, I had considered a 7-bit bitfield, a varchar ("MTWThFr" type deal) for the days of the week, but both of those seem like clunky solutions (the varchar being clunkier). Any suggestions?

• urllib alternative for iPhone

  - by Pr301

  hi, I am trying to create an iPhone application which in some point connects to the internet, fills an on-line form, fetches the resulting website, parses it and returns a string to the user. I want all this process to happen in the background. I know how to do this kind of things with python and urllib but in objc I can't find an alternative, from on-line search I found either sites that explain how to use webkit to retrieve webpages (I suppose this is for displaying them to the user) or how to parse an existing HTML file or string. Since I want the file to be retrieved from the internet and the whole process should be running in the background, neither of these solutions covers my needs.

• dismissViewControllerAnimated completion block presenter view and modal view flow

  - by Patricia LaRue

  I did find an answer to this title and I did do a little research but I'm still not getting the flow. Here is what I want to happen: 1) click a button on the presenter view to open a modal view. 2) retrieve some value and click a button to close the modal view....sending the value to the presentor view and execute a method. I get that this works like a callback but I still can't figure out where to put the callback stuff. So, how exactly do I do this? A) In the presentViewController completion block, should I include the presenter view method to execute when modal view is completed? Or: B) In the modal view's dismissViewControllerAnimated completion block, should I include the presenter view method to execute when modal view is completed? Can somebody help me with some sample code? Or at least help me get the flow of which block to put the code in? Thank you, P

• Parsing NSXMLNode Attributes in Cocoa

  - by Jeffrey Kern

  Hello everyone, Given the following XML file: <?xml version="1.0" encoding="UTF-8"?> <application name="foo"> <movie name="tc" english="tce.swf" chinese="tcc.swf" a="1" b="10" c="20" /> <movie name="tl" english="tle.swf" chinese="tlc.swf" d="30" e="40" f="50" /> </application> How can I access the attributes ("english", "chinese", "name", "a", "b", etc.) and their associated values of the MOVIE nodes? I currently have in Cocoa the ability to traverse these nodes, but I'm at a loss at how I can access the data in the MOVIE NSXMLNodes. Is there a way I can dump all of the values from each NSXMLNode into a Hashtable and retrieve values that way? Am using NSXMLDocument and NSXMLNodes.

• How to check a complex condition in Smarty(PHP)

  - by php html

  I need to display a section or another in a smarty template. My condition is simple: if a smarty value starts with a string I should display one section, otherwise the other smarty section should be displayed. I can change only the tpl files. {php} if (substr($url,0,4) != 'http') { {/php} section 1 {php} } else { {/php} section 2 {php} } {/php} The problem is that I can not read the url varible which was previously assigned using $smarty-assign. Basically, I'm looking for the smarty function that can be used to retrieve a value, or if there is a better solution.

• Is there a secure p2p distributed database?

  - by p2pgirl

  I'm looking for a distributed hash table to store and retrieve values securely. These are my requirements: It must use an existing popular p2p network (I must guarantee my key/value will be stored and kept in multiple peers). None but myself should be able to edit or delete the key/value. Ideally an encryption key that only I have access to would be required to edit my key value. All peers would be able to read the key value (read-only access, only the key holder would be able to edit the value) Is there such p2p distributed hash table? Would the bittorrent distributed hash table meet my requirements?' Where could I find documentation?

• How do I get the border-radius from an element using jQuery?

  - by S Pangborn

  I've got a div, with the following HTML and CSS. In an attempt to make my Javascript code more robust, I'm attempting to retrieve certain CSS attributes from the selected element. I know how to use the .css() getter to get elements, but how to get the border-radius using that method? jQuery's documentation is sparse. HTML: <div id="#somediv"></div> CSS: #somediv { -moz-border-radius: 5px; -webkit-border-radius: 5px; }

• PHP/MySQL: Storing and retrieving UUIDS

  - by Greg

  I'm trying to add UUIDs to a couple of tables, but I'm not sure what the best way to store/retrieve these would be. I understand it's far more efficient to use BINARY(16) instead of VARCHAR(36). After doing a bit of research, I also found that you can convert a UUID string to binary with: UNHEX(REPLACE(UUID(),'-','')) Pardon my ignorance, but is there an easy way to this with PHP and then turn it back to a string, when needed, for readability? Also, would it make much difference if I used this as a primary key instead of auto_increment? EDIT: Found part of the answer: $bin = pack("h*", str_replace('-', '', $guid)); How would you unpack it?

• c# hierarchy collection library? - anyone know of one (e.g. GetDirectChildren, GetAllChildren, GetPa

  - by Greg

  Hi, Does anyone know of a solid C# library / approach to manage a hierarchy/web type collection? This would be a library that would basic consist of the concept of nodes & relationships, for example to model web pages/files linked under a URL, or modeling IT infrastructure. It would have key methods such as: Node.GetDirectParents() Node.GetRootParents() Node.GetDirectChildren() Node.GetAllChildren() So it's smarts would include the ability to "walk the tree" of nodes based on the relationships when someone does ask for "give me all the children under this node" for example. It ideally include a persistence layer, to save/retrieve such data to/from a databases (e.g. with a Nodes and Relationships table). Thanks

• How to specify unique container styles for heterogenous hierarchies using SL3 and TreeView control

  - by rcecil

  Hello, Just look for strategies that have been successful in rendering hierarchies that represent inheritance structures using SL3/4 TreeViews. I need to render certain nodes differently than others, depending upon what kind of container they are (a choice between things, or simply a list of related things, etc.) So far, I've been very successful with the DataTemplate route: I've been able to use a technique described in Ted Glaza's post "Easy DataTemplateSelectors in Silverlight" (you may have retrieve a Google cache of this page). SO what I'm trying to discover is something on the order of a StyleSelector, not a DataTemplateSelector. I'm considering leveraging my current implementations of Glaza's pattern of selector objects to somehow detect the node type and set the ItemContainerStyle there, but it doesn't seem clear right now. Thanks for your thoughts.

• Retrieving Spotlight query used to open document in application

  - by vicvicvic

  If you search for something that opens Preview.app (e.g. a PDF file) in Spotlight, the application not only opens the file but actually copies the Spotlight query into the application's search field (for deeper search). iPhoto and Mail.app also do this. This is a really nice feature. Unfortunately, Apple does not document how it's implemented. Opening a document from Spotlight appears to simply send application:openFile to the application delegate. Is it possible to retrieve the user's Spotlight query somehow? Or is this a hardcoded feature of Spotlight?

• Get original element using .on

  - by RGraham

  When using jQuery's event delegation, is there a way to retrieve the element on which .on was called, as well as the element on which the event was called? jQuery: $(".item").on("click","a",function() { var link = $(this); // a tag var itemDiv = // what? }); HTML: <div class="item"> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> <a href="#">Link</a> </div>

• Facebook Graph API shows different results in me/home

  - by elekatonio

  Hi, When I do a GET with my browser (already logged-in at Facebook): https://graph.facebook.com/me/home?access_token={token} the results are different than doing the same via a FB app using Facebook C# SDK. Specifically, what the API is not returning are feeds posted by other applications. Why can be this happening? Can't an application retrieve updates from other applications even if it has the read_stream permission? I even requested for additional permissions: read_stream,user_activities,friends_activities,friends_likes,user_likes,read_requests but nothing has changed. What I need is to get ALL and the same stories an user would see at his FB news feed.

• Searching algorithmics: Parsing and processing a request

  - by James P.

  Say you were to create a search engine that can accept a query statement under the form of a String. The statement can be used to retrieve different types of objects with a given set of characteristics and possibly linked to other objects. In plain english or pseudo-code using an OOP approach, how would you go about parsing and processing statements as follows to get the series of desired objects ? get fruit with colour green get variety of apples, pears from Andy get strawberry with colour "deep red" and origin not Spain get total of sales of melons between 2010-10-10 and 2010-12-30 get last deliverydate of bananas from "Pete" and state not sold Hope the question is clear. If not I'll be more than happy to reformulate. P.S: This isn't homework ;)

• What's the proper way to use sqlite at xCode?

  - by Elliot Chen

  Hi, Experts: Can you please give some suggestions on sqlite using at xcode? Within my application, I use a sqlite DB to store all local data. Two methods can be used to retrieve those data during running time. 1, Load all the data into memory at initialization stage. (More memory used, less DB open/close operation needed) 2, Read corresponding records when necessary, free the occupied memory after using. (Good habit for memory using, but much DB open/close operations needs). I prefer to use method 2, but not sure whether too many DB opening/closing operations could affect app's efficiency. Or do you think I can 'upgrade' method 2 by opening DB when app launches and closing DB when app quits? Thanks for your suggestions very much!

• How do I find iTunes library folder on Mac and Windows?

  - by Boris

  I made an application that parse the iTunes library to retrieve its content. It works fine in most cases but if a user moved his library somewhere else than the default iTunes folder (see: http://lifehacker.com/238296/ultranewb--how-to-move-your-itunes-library-to-an-external-drive), then I need a way to find this path. On Mac, I was looking into ~/Library/Preferences/com.apple.iTunes.plist. There is a setting called "alis:1:iTunes Library Location" but it contains several parameters all concatenated and converted to hexadecimal. On Windows, I found this file "C:\Documents and Settings\\Application Data\Apple Computer\iTunes\iTunesPrefs.xml" that contains a setting "iTunes Library XML Location:1" but this one is encoded. Any help would be greatly appreciated. Thanks!

• Regular expression match, extracting only wanted segments of string

  - by Ben Carey

  I am trying to extract three segments from a string. As I am not particularly good with regular expressions, I think what I have done could probably be done better... I would like to extract the bold parts of the following string: SOMETEXT: ANYTHING_HERE (Old=ANYTHING_HERE, New=ANYTHING_HERE) Some examples could be: ABC: Some_Field (Old=,New=123) ABC: Some_Field (Old=ABCde,New=1234) ABC: Some_Field (Old=Hello World,New=Bye Bye World) So the above would return the following matches: $matches[0] = 'Some_Field'; $matches[1] = ''; $matches[2] = '123'; So far I have the following code: preg_match_all('/^([a-z]*\:(\s?)+)(.+)(\s?)+\(old=(.+)\,(\s?)+new=(.+)\)/i',$string,$matches); The issue with the above is that it returns a match for each separate segment of the string. I do not know how to ensure the string is the correct format using a regular expression without catching and storing the match if that makes sense? So, my question, if not already clear, how I can retrieve just the segments that I want from the above string?

• Bash scripting - Iterating through "variable" variable names for a list of associative arrays

  - by user1550254

  I've got a variable list of associative arrays that I want to iterate through and retrieve their key/value pairs. I iterate through a single associative array by listing all its keys and getting the values, ie. for key in "${!queue1[@]}" do echo "key : $key" echo "value : ${queue1[$key]}" done The tricky part is that the names of the associative arrays are variable variables, e.g. given count = 5, the associative arrays would be named queue1, queue2, queue3, queue4, queue5. I'm trying to replace the sequence above based on a count, but so far every combination of parentheses and eval has not yielded much more then bad substitution errors. e.g below: for count in {1,2,3,4,5} do for key in "${!queue${count}[@]}" do echo "key : $key" echo "value : ${queue${count}[$key]}" done done Help would be very much appreciated!

• SQL Querying for Threaded Messages

  - by Harper

  My site has a messaging feature where one user may message another. The messages support threading - a parent message may have any number of children but only one level deep. The messages table looks like this: Messages - Id (PK, Auto-increment int) - UserId (FK, Users.Id) - FromUserId (FK, Users.Id) - ParentMessageId (FK to Messages.Id) - MessageText (varchar 200) I'd like to show messages on a page with each 'parent' message followed by a collapsed view of the children messages. Can I use the GROUP BY clause or similar construct to retrieve parent messages and children messages all in one query? Right now I am retrieving parent messages only, then looping through them and performing another query for each to get all related children messages. I'd like to get messages like this: Parent1 Child1 Child2 Child3 Parent2 Child1 Parent3 Child1 Child2

• Remote XML retrieval

  - by rrrfusco

  I'm retrieving a remote XML file with wget -O remotefile localfile with a cron tab. Every so often the local file becomes malformed probably because of double whitespace (according to firefox) between the CDATA tags. Sometimes the parser gives an error for ' > ' missing, but upon checking the xml file the ' > ' exists... The remote xml file never gives malformed errors when called in the url. EDIT It seems CDATA is not parsed by the xml parser. (w3schools) Is there a way to set wget to retain wellformed XML? If not wget, What is a good way to continously retrieve a remote XML file and keep it well formed?

• Backup Google Calendar programmatically: https://www.google.com/calendar/exporticalzip

  - by Michael

  I'm struggling with writing a python script that automatically grabs the zip fail containing all my google calendars and stores it (as a backup) on my harddisk. I'm using ClientLogin to get an authentication token (and successfully can obtain the token). Unfortunately, i'm unable to retrieve the file at https://www.google.com/calendar/exporticalzip It always asks me for the login credentials again by returning a login page as html (instead of the zip). Here's the critical code: post_data = post_data = urllib.urlencode({ 'auth': token, 'continue': zip_url}) request = urllib2.Request('https://www.google.com/calendar', post_data, header) try: f = urllib2.urlopen(request) result = f.read() except: print "Error" Anyone any ideas or done that before? Or an alternative idea how to backup all my calendars (automatically!)
