• How can you stream results as json string downloads?

  - by midas06

  I'm interested in presenting results faster in my mobile app. Is it possible to stream results out as the string downloads? I'm thinking about implementing an IObservable to push out the results as they are downloaded, but I don't know what algorithm to use to properly piece together the data which could be incomplete at any given point. Hope that was clear enough. CLARIFICATION: Guess it wasn't clear enough. My issue is the string downloaded is quite long. It can often take 15-20 seconds or more to download. I want to reflect changes faster to my user, so I would like to use reactive extensions to pump out entities as soon as a complete one is received. My issue is I dont know how to build the parser that can pick out complete entities from an incomplete response string.

• 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>

• .htaccess cross browser

  - by lordsharp

  Hi, Im trying to load a custom error document for a 404 error using a .htaccess file on a linux server, the page gets the current page URL then redirects to another site (which is retrieved from a db) based on an id it retrieved from the URL. The current error documents are stored here: /error_docs/ - i dont have permission to upload anything other than the HTML files that are already in there /HTTPDocs/301redir.php is the site root where the .htaccess file is. i have used the following to load the 301redir.php page as the error doc, which works in FF but no other browsers. ErrorDocument 404 /310redir.php using .htaccess is my only real option for changing this, is there a way to get around this issue and make it work across all browsers?

  - by Nick Gorbikoff

  Hello. How would I get last 12 digits of a string using mysql? Let's say I have a varchar field with a tracking number, that may be anywhere from 5 to 20 varchars long. But I only need to select last 12 digits or less if there are less. so in a field = 12345678123456789012 I would only need to get what's in brackets field = 12345678[123456789012] I saw a few examples using mid, etc, but they dont' produce the desired result or I can't find an example that makes sense :-( Thank you.

• benefit os having a factory for object creation?

  - by ajsie

  im trying to understand the factory design pattern. i dont understand why it's good to have a middleman between the client and the product (object that the client wants). example with no factory: $mac = new Mac(); example with a factory: $appleStore = new AppleStore(); $mac = $appleStore->getProduct('mac'); how does the factory pattern decouple the client from the product? could someone give an example of a future code change that will impact on example 1 negative, but positive in example 2 so i understand the importance of decoupling? thanks

• SQL SELECT INSERTed data from Table

  - by Noam Smadja

  its in ASP Classic. MS-Access DB. i do: INSERT INTO Orders (userId) VALUES (123)" what i want to retrieve is orderNumber from that row. its an auto-increment number. so i did: SELECT orderNumber FROM Orders WHERE userId=123 but since it is on the same page, the SELECT returns: Either BOF or EOF is True, or the current record has been deleted.

• Using Wordpress as a CMS to a site AND blog (two completely different layouts for each). Duplicate i

  - by Somebody still uses you MS-DOS

  I'm going to create a website using Wordpress static pages feature. It's going to have a menu for all the created pages. A blog is going to be created as well. This blog has a completely different layout/menu from the main site, but within the same domain: "http://www.domain.com" is the website url, and "http://www.domain.com/blog/" is the blog url. I was thinking of installing two different Wordpress instances: /var/www/public_html/ and /var/www/public_html/blog/. Although it's a simple solution, users are going to be duplicated: if you change password in one system, you need to change in the other. So, I would like to know from you which other approaches are possible: create a "dynamic" theme (call a theme when in root domain, another whern /blog - dont even know if this is possible), or for example a plugin to syncronize users from both instances? Does Wordpress MU solve this problem for me? Thanks!

• How can I get a nstableview to send an action when the user double-clicks an editable cell

  - by overcyn

  I am trying to emulate the behavior found in finder and itunes. Single click on a selected object edits it. Double click opens the object. I have set the doubleAction of the tableView but like it says in the documentation. "If the double-clicked cell is editable, this message isn’t sent and the cell is edited instead." I dont want this. Is there a way i can get that message sent even if the cell is editable? I really have no idea how to begin implementing this. Any general pointers would be appreciated.

• CakePHP delete() function is not working

  - by Logic Artist

  Hello, Im just cracking open cakePHP (v1.3.2). I set it up on my local wamp server, seems to work fine except the delete() function doesn't work. I'm following their blog tutorial exactly, its as simple as it can be so I don't understand why its not working. Heres the function in my PostsController class: function delete($id = NULL) { $this->Post->delete($id); $this->Session->setFlash('The post with id: '.$id.' has been deleted.'); $this->redirect(array('action'=>'index')); } The "Delete" link's url looks like http://localhost/posts/delete/id:1 (where the id number matches the particular post, obviously). It redirects and sets the flash message, however there is no number where $id should be in the message, and the post isn't deleted. It seems the proper id is passed through the url, but I don't think it is getting into the function. I dont get it. Any ideas???

• How to call javascript function when url variable is sent

  - by mattlarkin

  Hello, heres basically what I need to get done. I have a jsp page which allows me to add/modify/delete an item. The items are stored in a database which I have controller classes to access(dont worry bout that part) When an item gets selected and deleted the id of the item gets sent to the controller to be processed. The item will not always be deleted if their is a foreign key constraint so I send either a delete=true or delete=false through url back to the jsp page. I would like to have it so a javascript function gets called displaying an alert saying the item was deleted or the item was not deleted. can someone please tell me the best way to do this? thank you

• Communication between .net winform and webform

  - by Pablo

  Hi, I need to make a webform communicate with a winform and back to the webform. The reason for this is it exists a webform software already made, and now it's needed the behavior of a .net component only available for winforms. We've tried going with Process.Start and shell.execute but with this approach the software hangs or it takes too long to respond. The webform also needs to be called from client pcs in the network, I think this adds another problem due to the non possibility of calling the execution of a file from a webform remotelly, but I dont know much about this technical issue we've read some articles about embedding a winform in a webform, sending data from a winform to a webform, etc. and we would like to know what's the recommend approach (if there is any) for handdling a situation like this.

• How to implement message passing in GNUradio?

  - by xuandl

  I need to implement message passing, my idea is to make some sort of message source (I inherit from public gr_sync_block) that works as a controller for another block (it has to send a message each 6 minutes). I read that is necessary to inherit from gnuradio::block -and by the way, installing grextras is mandatory-. In the .h file I added the #include and inherited from block"class JDFM_API jdfm_control : public gr_sync_block, public gnuradio::block". I know that I have redefine some things like the gnuradio::block constructor but I dont know what msg_signature is, I also don't get the relation between block's parameters and work parameter, the last thing that I am not sure is if I still can use gnuradio-companion if I create a block like this. I haven't been able to find a simple example of messages implementation. If anyone can guide me or show me an example, it would be awesome. Thanks in advance.

• The best practice to setup hierarchy data

  - by eski

  I'm trying to figure out the best practice to setup hierarchy data that i take from a database into some contoller that would show the hierachy. Basicly this would look like a normal tree but when you press the items that are under "chapters" you get a link to another page. I have these tables and this is the way they are connected Period Courses Subjects Chapters I select Period from a DropDownBox and then i want all the courses in that period to line up. Under each course would be the subject and under them are the chapers, typical hierarchy. The tables are linked together with refrences to each other in linear way. I have tried to use treeview to show this, but dont understand how to do it. I though i could use <ul><il> tags and do it at runtime. Reapeter or datalist, possible ? Is it better to do this with databinding in XAML or in code ?

• JPA @version - can it be used to calcualate version of a table entry

  - by OpenSource

  Hi, Please consider the following table (created using a corresponding entity) request ------- id requestor type version items 1 a t1 1 5 2 a t1 2 3 3 b t1 1 2 4 a t2 1 4 5 a t1 3 9 The above is what I want to achieve. The version field is a calculated field others are user provided. Basically the request's version needs to be calculated based on the combination of requestor and the type. The first occurance with a given combination will have a version 1 then version 2 and so on. I tried various things using @version on a different entity with just the three columns and joining the two entities using ManytoOne etc but I'm not able to get to the desired outcome. I dont want to confuse you with the things I tried. Since the objective is simple there should be an easier way I suppose? Can you please help? - any help greatly appreciated! thanks in advance
