• wordpress custom function for tabs creating duplicate tabs - simple php!

  - by user269959

  //checks that we are on current page and highlights tab as active if so if(is_page($page_name)){ echo " <li><a href='$href' class='current_page_item'> $tabname</a></li>"; } else { } if(is_single() && $singlelight=="this_one") { echo " <li><a href='$href' class='current_page_item'> $tabname</a></li>"; } else { echo " <li><a href='$href' > $tabname</a></li>"; } this code works as i would expect to highlight tabs using the wordpress function is_single and is_page. the problem is it generates 2 tabs for the active one in the menu. so my menu looks like this when 'home' is active.

• Processing variable number of form fields

  - by a_m0d

  I am working on a form which displays information about orders. Each order has a unique id, but they are not necessarily sequential on the form. Also, the number of fields can vary (one field per row on the form). The input into the form will not be mapped straight into the database, but will be added to the current value in the database, and then saved. An example of the form is in the picture below - the callout on the right shows the id for each row. I know how to generate the form like this, but I can't work out how I can easily process each of these rows reliably. I also know how to give each of the fields a unique identifier, like name="row-23", but how can I translate that name so that I can update the related record in the database?

• How to interrupt a waiting C++0x thread?

  - by doublep

  I'm considering to use C++0x threads in my application instead of Boost threads. However, I'm not sure how to reimplement what I have with standard C++0x threads since they don't seem to have an interrupt() method. My current setup is: a master thread that manages work; several worker threads that carry out master's commands. Workers call wait() on at least two different condition variables. Master has a "timed out" state: in this case it tells all workers to stop and give whatever result they got by then. With Boost threads master just uses interrupt_all() on a thread group, which causes workers to stop waiting. In case they are not waiting at the moment, master also sets a bool flag which workers check periodically. However, in C++0x std::thread I don't see any replacement for interrupt(). Do I miss something? If not, how can I implement the above scheme so that workers cannot just sleep forever?

• Web based API that can tell me if a number is a landline or cell phone?

  - by MikeN

  My application sends SMS messages to people, but the numbers entered in as their cell phone are sometimes land lines (this is user error or the user not really knowing if the contact number they have is a cell phone or landline.) I found a few websites that can tell me if a number is a landline or cell phone, but they do not offer programatic API's. Is anyone aware of a way a web application can figure out if a number can receive SMS messages? I guess a test SMS message is one way, but my current SMS gateway fails hard when it gets a landline number and doesn't tell me the landline number it tried to send the SMS to. I'll follow this up with my carrier, but I would love an easy way to let the user entering phone numbers in if they are a landline or cell number. Update: There are ways to figure this out. Take a look at http://www.phonevalidator.com, they can query a phone number and figure out if it is a landline or cell phone.

• Are there any was to link my program with Wine-compiled part?

  - by seas

  I am trying to use windows dll functionality in Linux. My current solution is a compilation of a separate wine application, that uses dll and transfer requests/responses between dll and main application over IPC. This works, but is a real overhead comparing to a simple dll calls. I see that wine-compiled program usually is a bootstrapping-script and some .so, which (according to file utility) is normal linux dynamically linked library. Are there any way to link that .so directly to my application? Are there any manual?

  - by Steoates

  I've got my claims set-up with MVC3 using azure and everything is going well. What I need to do now is extend the Claims Identity that's in the current thread / http context and add my own information (DOB, Address.. that sort of stuff) so my question is - where is the best place to do this? any examples would be great.. I presume that when the user is authenticated id then have to go to the DB and pull back the relevant record for the user then add it to the custom Claims Identity object? cheers. ste.

• Fix internal links in JS

  - by FB55

  I just created a script which extracts the article out of a webpage via server-side JS. (If your interested: it's used for http://pipes.yahoo.com/fb55/expandr .) I just got a little problem with internal links. Some pages include links like: /subfolder/subpage.html What I would need to do is fixing them and setting there root, like this: protocol://secondlevel.firstlevel/subfolder/subpage.html I'm using E4X for processing the page. I don't want to show my current creepy try, it's buggy and slow. Does anybody have a solution for me?

• Get countries within range of LAT/LONG coordinates

  - by ptrn

  Trouble! I'm looking for a way to find the countries within a given range of LAT/LONG coordinates. E.g.: When viewing a place in Africa in Google Maps, I get out which countries that are in my current view. This is a bit ambitious, and I think the main problem will be dealing with accuracy of the needed polygons. The accuracy of these don't need to be all that great, the borders can probably be tens of miles off, or even more. This will be needed for the entire world.

• Python .app doesn't read .txt file like it should

  - by Bambo

  This question relates to this one: Python app which reads and writes into its current working directory as a .app/exe i got the path to the .txt file fine however now when i try to open it and read the contents it seems that it doesn't extract the data properly. Here's my code - http://pastie.org/4876896 These are the errors i'm getting: 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: for index, item in enumerate( lines ): # iterate through lines 30/09/2012 10:28:49.103 [0x0-0x4e04e].org.pythonmac.unspecified.main: TypeError: 'NoneType' object is not iterable I kind of understand what the errors mean however i'm not sure why they are being flagged up because if i run my script with it not in a .app form it doesn't get these errors and extracts the data fine.

• Consolidating values in a junction table

  - by senloe

  I have the following schema: Parcels Segments SegmentsParcels ========= ========== ================= ParcelID SegmentID ParcelID ... Name SegmentID ... id A user of the data wants to consolidate Segments.Names and gave me a list of current Segment.Names mapped to new Segment.Names (all of which currently exist). So now I have this list in a temporary table with the currentID and newID to map to. What I want to do is update the SegmentID in SegmentsParcels based on this map. I could use the statement: update SegmentParcels set segmentID = [newID] from newsegments where segmentID = currentid but this will create some duplicates I have a unique constraint on ParcelID and SegmentID in SegmentParcels. What is the best way to go about this? I considered removing the constraint and then dealing with removing the duplicates (which I did at one point and could probably do again) but I was hoping there was a simpler way.

• Actionscript NetStream.play drops port in relative URLs

  - by Steve Middleton

  Hi, the current page my flash application is running from is http://localhost:3000/. I'm trying to play a video using NetStream.play(relativeURL) by using a relative URL (e.g. "myVideo.flv"), but when I look at the actual request made by actionscript, it's dropping the port number. (e.g. http://localhost/myVideo.flv). Is there something I can do on the flash side to make this work? Is anyone else having this problem?

• PHP regex to search across multiple lines

  - by Gaz

  I'm using preg_* in PHP to search for the pattern <!-- %{data=THIS GETS MATCHED}% --> and pull out the matched text. The pattern for this is: preg_match('#<!-- %{' . $knownString . '\s*=\s*(.*?)}% -->#', ...) What I would like it to do is search across multiple lines for the string. For example: <!-- %{data= THIS GETS MATCHED AND RETURNED }% --> How can I edit my current pattern to have this search ability?

• SQL Server 2005 - Find minimum unused value within a range

  - by Geo Ego

  I have a situation similar to the following question: Insert Data Into SQL Table Where my scenario differs is that I have a non-auto-incrementing primary key field that can have a range between 1000 and 1999. We only have about a hundred values in it thus far, but the maximum value has already been taken (1999), and there are gaps in the numbering sequence. Thus, I need to find a value that is between 1000-1999 and not taken. For instance, if my current values are, for example, 1000, 1001, 1003, and 1999, I would want the query to return 1002.

• Template deduction based on return type?

  - by Marlon

  I'd like to be able to use template deduction to achieve the following: GCPtr<A> ptr1 = GC::Allocate(); GCPtr<B> ptr2 = GC::Allocate(); instead of (what I currently have): GCPtr<A> ptr1 = GC::Allocate<A>(); GCPtr<B> ptr2 = GC::Allocate<B>(); My current Allocate function looks like this: class GC { public: template <typename T> static GCPtr<T> Allocate(); }; Would this be possible to knock off the extra < A and < B? Thanks

• basic json > struct question

  - by danwoods

  I'm working with twitter's api, trying to get the json data from http://search.twitter.com/trends/current.json which looks like: {"as_of":1268069036,"trends":{"2010-03-08 17:23:56":[{"name":"Happy Women's Day","query":"\"Happy Women's Day\" OR \"Women's Day\""},{"name":"#MusicMonday","query":"#MusicMonday"},{"name":"#MM","query":"#MM"},{"name":"Oscars","query":"Oscars OR #oscars"},{"name":"#nooffense","query":"#nooffense"},{"name":"Hurt Locker","query":"\"Hurt Locker\""},{"name":"Justin Bieber","query":"\"Justin Bieber\""},{"name":"Cmon","query":"Cmon"},{"name":"My World 2","query":"\"My World 2\""},{"name":"Sandra Bullock","query":"\"Sandra Bullock\""}]}} My structs look like: type trend struct { name string query string } type trends struct { id string arr_of_trends []trend } type Trending struct { as_of string trends_obj trends } and then I parse the JSON into a variable of type Trending. I'm very new to JSON so my main concern is making sure I've have the data structure correctly setup to hold the returned json data. I'm writing this in 'Go' for a project for school. (This is not part of a particular assignment, just something I'm demo-ing for a presentation on the language)

• Find the set of largest contiguous rectangles to cover multiple areas

  - by joelpt

  I'm working on a tool called Quickfort for the game Dwarf Fortress. Quickfort turns spreadsheets in csv/xls format into a series of commands for Dwarf Fortress to carry out in order to plot a "blueprint" within the game. I am currently trying to optimally solve an area-plotting problem for the 2.0 release of this tool. Consider the following "blueprint" which defines plotting commands for a 2-dimensional grid. Each cell in the grid should either be dug out ("d"), channeled ("c"), or left unplotted ("."). Any number of distinct plotting commands might be present in actual usage. . d . d c c d d d d c c . d d d . c d d d d d c . d . d d c To minimize the number of instructions that need to be sent to Dwarf Fortress, I would like to find the set of largest contiguous rectangles that can be formed to completely cover, or "plot", all of the plottable cells. To be valid, all of a given rectangle's cells must contain the same command. This is a faster approach than Quickfort 1.0 took: plotting every cell individually as a 1x1 rectangle. This video shows the performance difference between the two versions. For the above blueprint, the solution looks like this: . 9 . 0 3 2 8 1 1 1 3 2 . 1 1 1 . 2 7 1 1 1 4 2 . 6 . 5 4 2 Each same-numbered rectangle above denotes a contiguous rectangle. The largest rectangles take precedence over smaller rectangles that could also be formed in their areas. The order of the numbering/rectangles is unimportant. My current approach is iterative. In each iteration, I build a list of the largest rectangles that could be formed from each of the grid's plottable cells by extending in all 4 directions from the cell. After sorting the list largest first, I begin with the largest rectangle found, mark its underlying cells as "plotted", and record the rectangle in a list. Before plotting each rectangle, its underlying cells are checked to ensure they are not yet plotted (overlapping a previous plot). We then start again, finding the largest remaining rectangles that can be formed and plotting them until all cells have been plotted as part of some rectangle. I consider this approach slightly more optimized than a dumb brute-force search, but I am wasting a lot of cycles (re)calculating cells' largest rectangles and checking underlying cells' states. Currently, this rectangle-discovery routine takes the lion's share of the total runtime of the tool, especially for large blueprints. I have sacrificed some accuracy for the sake of speed by only considering rectangles from cells which appear to form a rectangle's corner (determined using some neighboring-cell heuristics which aren't always correct). As a result of this 'optimization', my current code doesn't actually generate the above solution correctly, but it's close enough. More broadly, I consider the goal of largest-rectangles-first to be a "good enough" approach for this application. However I observe that if the goal is instead to find the minimum set (fewest number) of rectangles to completely cover multiple areas, the solution would look like this instead: . 3 . 5 6 8 1 3 4 5 6 8 . 3 4 5 . 8 2 3 4 5 7 8 . 3 . 5 7 8 This second goal actually represents a more optimal solution to the problem, as fewer rectangles usually means fewer commands sent to Dwarf Fortress. However, this approach strikes me as closer to NP-Hard, based on my limited math knowledge. Watch the video if you'd like to better understand the overall strategy; I have not addressed other aspects of Quickfort's process, such as finding the shortest cursor-path that plots all rectangles. Possibly there is a solution to this problem that coherently combines these multiple strategies. Help of any form would be appreciated.

• jruby/activerecord-jdbc/tomcat/DB2 ready for enterprise?

  - by arkadiy

  I am trying to introduce RoR to my company and I have two ways of doing so in my mind: (1) rails/ibm_db2/passenger/DB2 - which is my preferable way but it is not really supported by company's infrastructure. (2) jruby/activerecord-jdbc/tomcat/DB2 - probably easier way to migrate relying on current infrastructure and java libs IF I have a proof this is an enterprise ready technology. Does anyone know if there is any prof that jruby/aciverecord-jdbc-adapter/DB2/tomcat is mature enough for production? Are there any problems I should know about during Development/Deployment/Runtime? My webapp is for a company intranet, around 200~400 active users.

• Handling Timeouts In A Website SQLCommand Object and c#

  - by user341684

  I'm using visual studio 2008 and sql server 2005 and everything is working just fine under normal use. However if a user is on a page for a while several minutes with no activity then clicks a button on occassion the site throws the following exception ... Procedure or Function "sp_name" parameter '@SomeParameterName', which was not supplied I'm also encountering this error in Visual Studio while debugging the application, in otherwords run the site from visual studio then make some change to the html in VS save the changes and refresh the page. The error is not consistent nor is the time the page has to stay idle in order for it to occur.... The current sql command object timeout is 30 secs and the website timeout is 30 minutes. Has anyone else experienced this scenario and what is the fix as I would not except anything to go out of scope until the website timeout occurs ... Any insight will be appreciated.

• [Seamless Handover of WiFi] Can we program to automatically join the WiFi with the most strongest si

  - by Dobby

  Hi all, I am making a iphone program, I wish that: it can sense and display the current signals of wifi, with strength, - as I checked, this cannot be done by official SDK, but there were some private library that can handle. 2. i wish it can always automatically join the best wifi with the most highest strength ( assume that all wifi APs have no password, and all are not remembered into the used-list inside iphone), which is something like "seamless handover"... I just guess that, there should be some APIs to let the system join one designated wifi signal from the list, and wish someone could help me. I would like to appreciate a lot : ) Thanks a lot!

• Get controller method caller (3rd party webservice)

  - by bastijn

  Is it possible to retrieve the URL of a 3rd party webservice calling my controller method? Things like Request.Current.Url refer to my own URL (/someController/someAction/). The 3rd party webservice is sending HTTP POST data to my /someController/someAction and I wish to send back a HTTP POST message to the caller of the method, the 3rd party webservice, without using return Content["some response"] which will force me to exit the method. Since the answer is plain text I would like to send it using HTTP Post. What I actually try to do is respond to the calling webservice without exiting my method (return Content() will exit) so I can call other methods to process the data send to me by the webservice. I want to first tell the webservice I received their stuff and than process, in this way when a processing error occurs the webservice at least will not resend old data. Is there another way to do this than building your own HTTP post?

• Django: query spanning multiple many-to-many relationships

  - by Brant

  I've got some models set up like this: class AppGroup(models.Model): users = models.ManyToManyField(User) class Notification(models.Model): groups_to_notify = models.ManyToManyField(AppGroup) The User objects come from django's authentication system. Now, I am trying to get all the notifications pertaining to the groups that the current user is a part of. I have tried.. notifications = Notification.objects.filter(groups_to_notify=AppGroup.objects.filter(users=request.user)) But that gives an error: more than one row returned by a subquery used as an expression Which I suppose is because the groups_to_notify is checking against several groups. How can I grab all the notifications meant for the user based on the groups he is a part of?

• Django Inherited Field Access

  - by Rick

  As of the most current version, Django does not allow a subclass to have a variable with the same name as a variable in its superclass, if that variable is a Field instance. I need a subclass to modify this variable, which I call 'department'. Calling my classes super and sub, I need sub to modify the department variable it inherits from super. If I redeclare it, Django throws a field error. Of course, if I don't, department is not in scope for reassignment. If super has no department I get database errors. I get weird behaviour when I try rewriting init: def __init__(self): super(theSuperClass, self).__init__() TypeError: super(type, obj): obj must be an instance or subtype of type Anyone have any idea how to do this?

• How to regularly merge two git repositories, one with submodules into one without

  - by smoothify

  I maintain a Drupal project in a git repository containing submodules. This works well for me overall, and I like the submodule approach. However, I would like to move my site to a hosting provider that offers deployment via git push but doesn't work with submodules. I would like to keep my current repository intact, and then when I'm ready to deploy, I would like to merge the changes from my repository into the deployment repository, but any submodules need to be exported into the tree. So, it needs to be (semi) automated, so I can just run a command or two and initiate the merge, and then push to the server. Ideally it would keep track of individual commits, but I wouldn't mind if it squashed them into a single commit. How would be the most effective way to achieve this?

• Drawing rubber band line during user drag

  - by Pete W

  In my iPhone app, I would like the user to be able to "connect" two of my views by: 1) starting a drag in View A 2) as they drag towards View B, a straight line with one end in View A and the other end under at the current drag point, animates in a rubber-band fashion 3) when/if they release in View B, the line is then shown between the two views I've seen examples of dragging and dropping views, and other examples of animations, but I haven't seen one that is a simple example of this kind of user-directed animation. Any pointers towards examples or the specific docs I should be looking at would be appreciated. If this turns out to be trivial - my apologies. Although I've done quite a bit of development, I'm just getting started in the iPhone SDK and Core Graphics.
