• Have a link that is imported in xml, clickable to execute a function

  - by Benjamin Sterling

  Ok, here's the question, I have an xml doc that is being import into an AS3 file and then with .htmlText, appending it to a movie clip. An example of what this looks like is: <abstract><![CDATA[<p><strong>AEO Times Square</strong> Store Wins Prestigious SEGD Merit Award for Dynamic Environments <a href='event:OpenArticle1'>View Article</a></p>]]></abstract> What I'd like to have happen is when I click that view article link that I can call a function passing in "OpenArticle1". Thanks in advance.

• Mysql SET NAMES UTF8 - how to get rid of?

  - by Nir

  In a very busy PHP script we have a call at the beginning to "Set names utf8" which is setting the character set in which mysql should interpret and send the data back from the server to the client. http://dev.mysql.com/doc/refman/5.0/en/charset-applications.html I want to get rid of it so I set default-character-set=utf8 In our server ini file. (see link above) The setting seems to be working since the relevant server parameters are : 'character_set_client', 'utf8' 'character_set_connection', 'utf8' 'character_set_database', 'latin1' 'character_set_filesystem', 'binary' 'character_set_results', 'utf8' 'character_set_server', 'latin1' 'character_set_system', 'utf8' But after this change and commenting out set names utf8 call still the data starts to come out garbled. Please advise....

• Masking to Transparent returns empty image

  - by Tibi

  Hi there, I'm trying to put white color in my images to transparent with the following code. Problem is that "CGImageRef maskedTransparent" is blank. I don't understand because the code I'm using is nearly a copy paste from the doc ... Any idea ? (UIImage*) maskImage:(UIImage *)image withMask:(UIImage *)maskImage { CGImageRef maskRef = maskImage.CGImage; CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef), CGImageGetHeight(maskRef), CGImageGetBitsPerComponent(maskRef), CGImageGetBitsPerPixel(maskRef), CGImageGetBytesPerRow(maskRef), CGImageGetDataProvider(maskRef), NULL, false); CGImageRef masked = CGImageCreateWithMask([image CGImage], mask); //Array defining min & max RGB values to be transformed to transparent colors. float maskingMinMax[6] = {255, 255, 255, 255, 255, 255}; //masking image to remove range in maskinLinMax CGImageRef maskedTransparent = CGImageCreateWithMaskingColors(masked, maskingMinMax); return [UIImage imageWithCGImage:maskedTransparent]; }

• Relative XPath selection using XmlNode (c#)

  - by maxp

  Say i have the following xml file: <a> <b> <c></c> </b> <b> <c></c> </b> </a> var nodes = doc.SelectNodes("/a/b"); will select the two b nodes. I then loop these two nodes suchas: foreach (XmlNode node in nodes) { } However, when i call node.SelectNodes("/a/b/c"); It still returns both values and not just the descendants. Is it possible to select nodes only descening from the current node?

• NSFetchedResultsController doesn't fetch up the child-parent moc chain?

  - by Kronusdark

  I cannot find any clarification on this, so it may be a bug. Problem is, I have a series of parent-child Managed Object Context's. When I save on a child context the changes get pushed up to the parent, and I can fetch using a plain old NSFetchRequest. However, if I rely on an NSFetchedResultsController to pull these changes into a sibling context to the first, they do not see them. calling -(void)performFetch: error; doesn't seem to pull the changes either. After a restart of the app, all new data is available. My hypothesis is that NSFetchedResultsController only fetches from its current context and will not follow the chain to the persistent store. Can someone please set me straight here? Am I going to have to use notifications to monitor changes on other contexts? and finally, is this mentioned somewhere in the doc's? I cannot find it for the life of me.

• iOS Facebook Access Token To Get User Wall Feed (status)

  - by Felix

  [DISCLAIMER : None of the access token or ID below here are real] I've done research for three solid days and no result on how to get user wall feed(post). I have used https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials and get the access token which is something like this access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN and then https://graph.facebook.com/100005939123542/feed?access_token=454345994651138|bAMGfuW-ueNXGCahley7ga125HN It gives me general information such as user's likes, name, id, current city... but NOT user's wall posts. I've learned that there are three types of access token, which is App Token, User Token, and Page Token. In order to get user/feed by using graphAPI, I need to request to get User Token, but there's NO information in the lousy Facebook Doc! (Which frustrated me the most!) In order to generate the user access token, we need to set some permission, generate the access token, and GET the user's wall feed, which is in JSON format. My question is : How do I get the User Access Token in order to get user wall post in iOS Xcode?

• Out-Of-Memory while doing Core Data migration

  - by Kamchatka

  Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?

• jQuery: Self Executing Plugin?

  - by GnrlBzik

  I am working on expansion of my jQuery plug-in authoring knowledge, just playing around with my own ideas for learning benefits. So i was wondering how you guys tackle the need of plugin executing without any user specific input. So I have a need for plug-in that executes right away after document is ready, without any user's specific input just as long as doc is loaded, so the only way I see how to execute plug-in on it's own is to attach handler to ready listener that executes my function which I extended the jQuery with. And because this needs to be self enclosed, part of the code, I attach handler to event listener within the function. So how else could one tackle this? Any take at this is appreciated. Thank you in advance everyone.

• Adding custom/new properties to any file regardless of type and extension e.g. setting 'Author' on a

  - by Vaibhav Garg

  I want the ability add properties and tags to a file (specifically ebook files and ebook related properties in Windows 7 but interested to go so for as many OSes as possible) For e.g. Example.txt or Example.doc or Example.epub should all store and carry properties like 'Author', 'Publication date', 'Tags' etc.. the properties should be stored with the file itself. Such that if it is transferred to another system it retains the properties (even if i need to install 'my app' to support this function on the other machine) How do I make this possible using .net (preferred) and what file system concepts should I learn to understand the underlying concepts and limitations to be able to implement this feature? Any application that already does this? Thank you

• MySQL indexes: how do they work?

  - by bob-the-destroyer

  I'm a complete newbie with MySQL indexes. I have several MyISAM tables on MySQL 5.0x having utf8 charsets and collations with 100k+ records each. The primary keys are generally integer. Many columns on each table may have duplicate values. I need to quickly count, sum, average, or otherwise perform custom calculations on any number of fields in each table or joined on any number of others. I found this page giving an overview of MySQL index usage: http://dev.mysql.com/doc/refman/5.0/en/mysql-indexes.html, but I'm still not sure I'm using indexes right. Just when I think I've made the perfect index out of a collection of fields I want to calculate against, I get the "index must be under 1000 bytes" error. Can anyone explain how to most efficiently create and use indexes to speed up queries? Caveat: upgrading Mysql is not possible in this case. Using Navicat Light for db administration, but this app isn't required.

• jQuery compatible JavaScript documentation generator

  - by clyfe

  I need to choose a documentation generator (similar to jdoc in java or rdoc in ruby) for my javascript project that (built with jquery, underscore and backbone) Candidates: jsdoc toolkit pdoc natural docs docco YUI doc doctool http://jquery.bassistance.de/docTool/docTool.html other ? Requirements should work with jquery, underscore and backbone. that means object-literal methods etc I really like pdoc but its too centered around prototype, poorly documented, and I don't want to make extra files (sections?) to make it work (not sure about this) docco is nice but I want structured output (as in menu + class/func structure like jdoc) must be command line/makefile compatible (not web pastie) Tips, tricks, tutorials, success stories, advice greatly welcomed. Why Doesn't jQuery use JSDoc?

• What does ER_WARN_FIELD_RESOLVED mean?

  - by VolkerK

  When SHOW WARNINGS after a EXPLAIN EXTENDED shows a Note 1276 Field or reference 'test.foo.bar' of SELECT #2 was resolved in SELECT #1 what exactly does that mean and what impact does it have? In my case it prevents mysql from using what seems to be a perfectly good index. But it's not about fixing that specific query (as it is an irrelevant test). I found http://dev.mysql.com/doc/refman/5.0/en/error-messages-server.html butError: 1276 SQLSTATE: HY000 (ER_WARN_FIELD_RESOLVED) Message: Field or reference '%s%s%s%s%s' of SELECT #%d was resolved in SELECT #%d isn't much of an explaination.

• Is it good to continue as MFC developer or good to know .NET as well?

  - by AKN

  Normally people say MFC is little clumsy. It makes UI developement slightly difficult to maintain since it has lot of auto generated code. It has good architecture (doc/view) but is not transparent like Win32 programming to understand how window program works in the background. So with this situation, is it good to extend the exposure on MFC programming or better to switch to .NET since for faster UI design with ease in maintenance. How globally companies are looking into MFC as a technology for UI developments. Are they comfortable in supporting their developers to continue with MFC or looking for changing their development technology.

• Qt4.6: QTextDocument <HR> tag prints only very thin, almost invisible hair lines

  - by hurikhan77

  When printing a QTextDocument with doc->print() I almost cannot see the horizontal rules inserted by <hr>. When printing to PDF these are clearly visible. But when printed to a printer these lines are very very thin lines, almost invisible on the paper. How do I fix this? I currently helped myself by inserting an <img> with a black pixel but this is very cumbersome as I have to exactly figure out the proper pixel width by trial and error.

• Tomcat 6 configuration example for Ubuntu Linux?

  - by intargc

  I'm very new to Tomcat and I'm having some issues figuring out how to set it up. I set it up on Ubuntu Linux and started reading and trying to follow the information given on the apache website here: http://tomcat.apache.org/tomcat-6.0-doc/deployer-howto.html Apparently I'm missing something. I have a WAR named MyWebapp.war and it's in a directory /home/mywebapp. In /etc/tomcat6/Catalina/localhost/MyWebapp.xml, I have the following line: <Context path="/MyWebapp" docBase="/home/mywebapp" antiResourceLocking="false" /> Everything else is the default configuration that came with tomcat6 via the Ubuntu package. When I restart Tomcat and try to go to http://localhost:8080/MyWebapp, I get a 404. The WAR file isn't unpacked and nothing seems to be working. I'm going to be deploying two Grails applications on this server with Tomcat. Is there a more straight forward way to do this?

• Is there an IDE that provides code completion for Python

  - by Justin Walgran

  I am quite fond of the Intellisense code completion baked into Microsoft Visual Studio. I find that I only type 2 to 4 characters of any given keyword which drasticaly speeds up my coding. Now that I have been spending time writing some Python code I find myself reaching for ctrl+space. Are there any IDEs that support code completion in Python? I do my python development on a Mac so an OS x tool would be preferable. It seems like the doc string property of Python methods is a perfect match for inline API discovery.

• Avoiding string copying in Lua

  - by Matt Sheppard

  Say I have a C program which wants to call a very simple Lua function with two strings (let's say two comma separated lists, returning true if the lists intersect at all, false if not). The obvious way to do this is to push them onto the stack with lua_pushstring, which works fine, however, from the doc it looks like lua_pushstring but makes a copy of the string for Lua to work with. That means that to cross over to the Lua function is going to require two string copies which I could avoid by rewriting the Lua function in C. Is there any way to arrange things so that the existing C strings could be reused on the Lua side for the sake of performance (or would the strcpy cost pale into insignificance anyway)? From my investigation so far (my first couple of hours looking seriously at Lua), lite userdata seems like the sort of thing I want, but in the form of a string.

• How do I set the dataProvider for an <s:List> component to be an XML file?

  - by Matt Calthrop

  I've got the latest Beta of Adobe Flash Builder 4. I want to use a <s:List> component, and specify the dataProvider as being an XML file. However, after loads of research (including looking at doc links off labs.adobe.com), I still can't figure out how to do it. The XML file will look something like this: <?xml version="1.0" encoding="ISO-8859-1"?> <imageList> <image location="path/to/file1.jpg" /> <image location="path/to/file2.jpg" /> <image location="path/to/file3.jpg" /> </imageList>

• Documenting a policy based design

  - by academicRobot

  I'm re-working some prototype code into a policy based design in C++, and I'm wondering what the best practice is for documenting the design. My current plan is to document: Policy hierarchy Overview of each policy Description of each type/value/function in each policy I was thinking of putting this into a doxygen module, but this looks like it will be a bit awkward since formatting will have to be done by hand without code to base the doc on (that is, documenting the policies rather than the implementation of the policies). So my questions are: Are there other aspects of the design that should be documented? Are there any tricks to doing this efficiently in doxygen? Is there a tool other than doxygen thats better suited to this? What are some examples of well documented policy based design? This is my first serious attempt at policy based design. I think I have a working grasp of the principles, but whatever naivety I expose in this question is fair game for an answer too.

• Android MapView with High Res tiles?

  - by Nemi

  I have created a simple map app that shows the local garage sales in my town. It was simple enough to create and I parse out the Google Maps (html) xml doc that the local paper uses on their google maps mashup on their website. I have noticed that the Map Tiles used in the MapView class are not as high-res as the tiles used in the real Android Google Maps app (I have a Droid). I have searched the docs and google, but I cannot find any info on this. Actually, I can't even find anyone mentioning this, which surprises me and makes me think I am missing something simple. Is this a case of Google making the APIs available, but at a lower quality, or am I missing some setting that enables higher quality map tiles?

• Facebook API returning wrong unread thread count

  - by houbysoft

  I'm trying to query the thread FQL table to get all unread messages, and also the count of unread items in the thread. This is how I query the table: SELECT thread_id,updated_time,snippet,snippet_author,unread FROM thread WHERE folder_id=0 AND unread!=0 From reading the doc to which I linked above, it seems to me that unread should include the count of unread messages in the thread. However, I just tested the above call and Facebook gives me back a value of unread=1, despite the thread in question having 4 unread items. This is how the thread looks on facebook.com (notice the (4), showing that unread should be 4): This is what the API returns to me, which is wrong (notice the "unread":1): { "data":[ { "name":"messages", "fql_result_set":[ { "thread_id":"BLAH BLAH BLAH", "updated_time":1333317140, "snippet":"BLAH BLAH BLAH", "snippet_author":BLAH, "unread":1 } ] } ] } Am I doing something wrong, or is this a bug?

• Grails multi column indexes

  Can someone explain how to define multi column indexes in Grails? The documentation is at best sparse. This for example does not seem to work at all: http://grails.org/GORM+Index+definitions I've had some luck with this, but the results seems random at best. Definitions that works in one domain class does not when applied to another (with different names of course). http://www.grails.org/doc/1.1/guide/single.html#5.5.2.6%20Database%20Indices Some working examples and explanations would be highly appreciated!
