• How to email CLLocationCoordinate2D as a link

  - by lucasweb

  I am trying to emulate the Maps 'Share Location' via email functionality. I have the latitude and longitude of my location and am currently using it to display the location on a map via MKMapView. I also have functionality that composes an email from the app and I would like to include the location in it but can not figure out how to construct a link, using the longitude and latitude. I have seen other apps with apps with this functionality so I know it is possible. Any help would be much appreciated. Thanks in advance.

• Why do I get the error "X is not a member of Y" even though X is a friend of Y?

  - by user1232138

  I am trying to write a binary tree. Why does the following code report error C2039, "'<<' : is not a member of 'btree<T'" even though the << operator has been declared as a friend function in the btree class? #include<iostream> using namespace std; template<class T> class btree { public: friend ostream& operator<<(ostream &,T); }; template<class T> ostream& btree<T>::operator<<(ostream &o,T s) { o<<s.i<<'\t'<<s.n; return o; }

• Any side effect of not using USES_CONVERSION

  - by Yan Cheng CHEOK

  Recently, I have a utilities function of // T2CA #include "ATLCONV.H" std::string Utils::CString2String(const CString& cString) { #if _MSC_VER > 1200 // Convert a TCHAR string to a LPCSTR // construct a std::string using the LPCSTR input CT2CA tmp(cString); std::string strStd (tmp); #else // Deprecated in VC2008. // construct a std::string using the LPCSTR input std::string strStd (T2CA (cString)); #endif return strStd; } I do several simple test it seems work fine. However, when I google around, I see most usage of T2CA in VC6, before they call, they will invoke USES_CONVERSION; Is there any thing I had missed out? Shall I invoke my function by : #else // Deprecated in VC2008. // construct a std::string using the LPCSTR input USES_CONVERSION; std::string strStd (T2CA (cString)); #endif

• Drupal: How to render a form and table on same page

  - by Aaron

  Can someone help me render a form and table on the same page? I'm sure it's easy, but can't think of how to do it. Here's hook_menu: function ncbi_subsites_menu() { $items = array(); $items['admin/content/ncbi_subsites'] = array( 'title' => 'NCBI Subsites Module', 'description' => 'Informs Drupal about NCBI subsites as defined by the Content Inventory database', 'page callback' => 'ncbi_subsites_show_main_page', 'access arguments' => array( 'administer site configuration' ), 'type' => MENU_NORMAL_ITEM, ); return $items; } Here's the callback: function ncbi_subsites_show_main_page() { $subsites = ncbi_subsites_get_subsites_from_inventory(); // fnc returns associative array from inventory, defined in include return ncbi_subsites_make_table( $subsites ); } In the callback I call some helper functions that return a themed, paged table. What I want is a small form above the table. How would I that?

• WCF and a developer key like Google map API. What exactly am I looking for?

  - by Scott

  I want to allow access to a WCF service to only those requests that contain a developer key. This is similiar to how the Google Maps API works. Register for a developer key and include that key in your requests. Anyone can get a key. How you get a key is undecided but is being discussed. For now, we'll email you a key. The service is up and running so I will be adding this on. I just need to know what I'm looking for so I can figure out what I need to do. Makes sense, right?!?! What is this scheme called? What should I search for? Any suggested links / books / whitepapers?

• Convert a number from string to integer without using inbuilt function

  I am trying this technique but error is coming.

• Strings, regexp and files

  - by A Moose

  <?php $iprange = array( "^12\.34\.", "^12\.35\.", ); foreach($iprange as $var) { if (preg_match($var, $_SERVER['REMOTE_ADDR'])) { I'm looking to have a list that will constitute each of the values inside the array. Let's call it iprange.txt, from which I would extract the variable $iprange. I would also be updating the file with new ranges, but I also want to convert those strings to regexp if that's something that's needed in php, as it is in the above example. If you could help me with the two following issues: I understand that somehow I would be using an array include, but I'm not sure how to implement it. I would like to run a cron that would update the text file and turn it into a regexp acceptable for use in the above example, if you think regexp is a good idea and there isn't another option. I know how to apply a cron in a directadmin gui, but I don't know what the cronned file would look like.

• Override properties block when including a psake script in an other psake script

  - by DanceAlot

  I am new to psake and I have this issue: I have 2 psake scripts: (1): base_tasks.ps1: properties{ $a = "hello" $b = "hi" } task One{ Write-Host $a } (2): install.ps1 Include .\base_tasks.ps1 properties{ $a = "Goodbye" $b = "Adjeu" } task default -depends One Now, is it possible to override the properties and variables from file 1? I want to use file 1 as "base tasks" and use the tasks in the install.ps1 and override the properties. Or do I have to do that an other way? I will invoke install.ps1 and use my $a and $b from install.ps1. DanceAlot

• Can't add libraries to Eclipse Android project

  - by neuromancer

  I'm trying to get the Hackbook for Android project to work in Eclipse. One of the things I need to do is remove that invalid reference and include that project I made. I did this before, but then I started over and now it doesn't work. Here is where I add the project. If I click "Apply" and then "OK" everything seems to be fine, but it isn't, because when I go back to this screen, none of the changes I made are there. Why isn't it saving my changes? How am I supposed to do this?

• Finding relative libraries when using symlinks to ruby executables

  - by dgtized

  Imagine you have an executable foo.rb, with libraries bar.rb layed out in the following manner: <root>/bin/foo.rb <root>/lib/bar.rb In the header of foo.rb you place the following require to bring in functionality in bar.rb: require File.dirname(__FILE__)+"../lib/bar.rb" This works fine so long as all calls to foo.rb are direct. If you put as say $HOME/project, and symlink foo.rb into $HOME/usr/bin, then __FILE__ resolves to $HOME/usr/bin/foo.rb, and is thus unable to locate bar.rb in relation to the dirname for foo.rb. I realize that packaging systems such as rubygems fix this by creating a namespace to search for the library, and that it is also possible to adjust the load_path using $: to include $HOME/project/lib, but it seems as if a more simple solution should exist. Has anyone had experience with this problem and found a useful solution or recipe?

• Doesn't Spring really support Interface injection at all?

  - by mrCoder

  Hi I know that Spring doesn't supports Interface injection and I've read that many a times. But today as I came across an article about IOC by Martin Fowler (link), it seems using ApplicationContextAware in Spring is some what similar to the Interface injection. when ever Spring' context reference is required in our Spring bean, we'll implement ApplicationContextAware and will implement the setApplicationContext(ApplicationContext context) method, and we'll include the bean in the config file. Is not this the same as Interface injection, where where telling the Spring to inject (or), say, pass the reference of the context into this bean? Or I m missing something here? Thanks for any information! ManiKanta

• C++/CLI Missing MSVCR90.DLL

  - by Mitch

  I have a c++/cli dll that I load at runtime and which works great in debug mode. If I try and load the dll in release mode it fails to load stating that one or more dependencies are missing. If I run depends against it I am missing MSVCR90.DLL from MSVCM90.DLL. If I check the debug version of the dll it also has the missing dependency, but against the debug (D) version. I have made sure debug/release embed the manifest file. I read something about there being issues with the app loading the dll being build as Any CPU and the dll being built as x86, but I don't see how to set them both to x86. I am using VS2010. Anyway, I've been messing around for a while now and have no idea what is wrong. I'm sure someone out there knows what is going on. Let me know if I need to include additional info.

• server reboot has caused django project to lose directories

  - by wmfox3

  A fully functional Django project as well as a couple in development have all broken following the rebooting of the server. In addition to some pieces of the Django admin returning errors as well as missing .js and .css files, I'm getting errors like this when viewing pages that include images uploaded through the admin. Exception Type: TemplateSyntaxError Exception Value: Caught an exception while rendering: (2, 'No such file or directory') Exception Location: /usr/lib/pymodules/python2.6/django/template/debug.py in render_node, line 81 Python Executable: /usr/bin/python Python Version: 2.6.4 So did the reboot stomp on some part of my configuration/setup or did it fail to restart a critical piece?

• How will ASP.NET AJAX be licensed?

  - by hbb

  It would be very useful if somebody could indicate what the plans are for releasing and licensing the AJAX extensions. The EULA for Beta 2 states that the software may be used for development and for web site deployment only. Redistribution is explicitly forbidden. Does that imply that it is going to be released under terms different from the .NET framework and ASP.NET or is it just a precaution to prevent developers shipping the Beta? It seems too risky to include AJAX in new products before there is some indication what the model is going to be....

• Scraping non-absolute URL

  - by cooldude

  I am trying to scrape www.weather.bm. I want all 10 radar images, but I can only get one (the image updates regularly) and it's not a absolute image url. I was hoping I could use the image as a image slideshow like the link but dont know how. Also, how can I remove images/Radarlegend.png? I just need the radar images. Here is my code: include('simple_html_dom.php'); $html = file_get_html('http://www.weather.bm/radarMobile.asp'); foreach($html->find('img') as $element) echo $element->src . '<br>' My output is: <div id="main"> images/Radar/CurrentRadarAnimation_100km_sri/100km_sri-radar-2011-01-04-1556.jpg<br>images/Radarlegend.png<br></div> </div>

• beginner Linq syntax and EF4 question

  - by user564577

  Question With the following linq code snip I get a list of clients with address filtered by the specifications but the form of the entities returned is not what i had expected. The data is 1 client with 2 addresses and 1 client with 1 address. The query returns 3 rows of clients each with 1 address Client 1 = Address1 Client 1 = Address2 Client 2 = Address3 var query = from t1 in context.Clients.Where(specification.SatisfiedBy()).Include("ClientAddresses") join t2 in context.ClientAddresses.Where(spec.SatisfiedBy()) on t1.ClientKey equals t2.ClientKey select t1; My expectation was a little more like a list with only two clients in it, one client with a collection of two addresses and one client with a collection of one address. Client 1 = Address1 / Address2 Client 2 = Address3 What am I missing??? Thanks!

• Can sIFR js files be combined into 1 js file?

  - by Logan Stellway

  In the new sifr 3, the author has implemented the ability to combine the css files into 1 file. There are 4 .js files total and I was wondering if there were any ideas how to combine these files for a faster loading time on the client side and also I was wondering if there was any way to just include the sIFR css styles in an already existing css file. These modifications would greatly decrease the load/waiting time on the end user and I was wondering if there was any thought for that on upcoming builds or if there were any ideas on how to accomplish this idea.

• Django: Site-Wide URL Prefix

  - by Tom

  I've built a Django site that will live at the root when it's live. Right now it's functioning perfectly at the IP address. For testing purposes, the client has pointed a proxy url at it, but the url has /folder/path in it, so none of the URL patterns match. I put (/folder/path)? into all the url patterns so they now respond, but all of the links are broken because I'm using the {% url %} tag and while the url patterns will match the optional path, they don't include it in that tag. Clearly I can just hard-code /folder/path into all of my urls (well, into all of the url includes) until testing is complete, but is there a better way to do this?

• What's causing "NoMethodError: undefined method `include?' for nil:NilClass"

  - by NudeCanalTroll

  I have a Book model in my Rails application, with various properties (aka columns in the book db table). One of these properties is "ranking". Recently, may app has started to throw NoMethodError: undefined method 'include?' for nil:NilClass for the following code: def some_method(book, another_arg) return book.ranking unless book.ranking.blank? ... end However, it's not consistent. The vast majority of the time, accessing book.ranking works -- the error is thrown maybe 2-4% of the time. If I change the code to book[:ranking] or book['ranking'] instead of book.ranking, it works 100% of the time. Any ideas?

Is there a general solution for this kinda problem? UPDATE Some answers recommend install the VS redist,but I'm not sure whether or not it will affect my installed Visual Studio 9, can someone confirm?

• PHP Echo current filename without extension

  - by Christian Nikkanen

  I'm working on a very simple homemade CMS that simply uses a rich text editor and database to save the website contents and displays them to visitors. Heres the save.php that saves it: <?php include 'mysqlconnection.php'; mysql_query("UPDATE Content SET Content='$_POST[edit]' WHERE PageName='$_POST[PageName]'"); mysql_close($con); ?> <?php header('Location:http://xxx.com/Kayttoliittyma'); ?> It just saves it to the database. The pagename part is the part where I need to echo the filename without the extension. It would echo to the forms hidden field. But how?

• How do I stop intellij from adding specific jars to the classpath when debugging?

  - by AlecZorab

  When I debug an application in intellij, it insists on including all the jars in side my jre/lib folder and sub folders. Unfortunately, one of the libraries I use manually loads each class on the classpath at startup to reduce loading times during operation. As a result, debugging my app immediately results in the process spinning at 100% and then eventually dying. If I take the command line intellij uses and remove the jars in the lib folder from the classpath, the application executes as expected. How do I make intellij not include the jre libs?
