  Hi guys: I get two frames, says A and B. Clicking a link in A will trigger page in B changing from URL_A to URL_B.

• C# asp.net MVC: When to update LastActivityDate?

  - by Oskar Kjellin

  I'm using asp.net mvc and creating a public website. I need to keep track of users that are online. I see that the standard way in asp.net of doing this is to keep track of LastActivityDate. My question is when should I update this? If I update it every time the users clicks somewhere, I will feel a performance draw back. However if I do not do that, people that only surf arround will be listed as offline. What is the best way to do this in asp.net MVC?

• How can I use form_remote_tag to update an acts_as_taggable_on field?

  - by Angela

  I have a model called Company which is acts_as_taggable_on. When I am /SHOWing a Company (e.g. company/15) I want to be able to see a form that allows me to add tags. I suppose this would be easier by just allowing at edit but sometimes I want to go back and just add tags. This is what I tried to do and I get an error: <div id = 'tags'> <strong>Tags:</strong> <% form_remote_tag(:url => {:action => 'update'}, :update => 'tags') do %> <%= text_field :company, :tag_list %> <%= submit_tag 'Save' %> <% end %> </div> Thanks!

• Should my web based app be a consumer of my api?

  - by seanbrant

  I will be developing a mobile app (iPhone) and a web based app (Django) soon. For the mobile app I will be creating a REST api (most likely using Django) to send data back and forth from phone to server. When I comes time to create the web based version does it make sense to just create it as any other client of the api. In other words both the mobile app and the web app will get there data from an external API over HTTP. Or should the web based app have direct access to the database that the api is using and just get its data that way?

• PHP multiple __autoload functions *without* the use of spl_register_autoload?

  - by Keith Palmer

  I'm an author of a growing library of PHP + QuickBooks related code. I'd like to utilize PHPs __autoload() function, however my code is a library that other people can include() into their own applications, so I can't rely on __autoload() being not already defined. Is there a way to have multiple __autoload() functions? I saw spl_autoload_register() in the PHP manual, but not all of my users have the SPL extension installed, so I can't rely on that. If there was a way to fall-back to using this and use normal require/include statements by default, I might consider that. Does anyone else have any other clever solutions to this issue? It seems like a glaring oversight to only be able to have a single __autoload() function...

• How can I use jQuery for messing with a particular div, but not in the current document - in a varia

  - by bisaram

  How can I use jQuery for messing with a particular div, but not in the current document - in a variable, that contains HTML? The point is that I want to show a preview of a page (a piece of it's content) in a modal window, when the link to this page is clicked. Well, onClick I load this whole HTML into a variable via JSON and then... how would I find a particular div I need in it? It's gonna be almost impossible to parse it with PHP before converting it into JSON and giving back to jQuery processor because of a deep hierarchy. Basically, is it even possible to do smth like $( 'div#some-id' ).blabla(); not for the current document, but for the document, stored in a variable? Thx everyone in advance.

• How to perform a cell deselection when a user returns to a table view?

  - by Panagiotis Korros

  I am using a UITableView to display a list of cells, when the user selects a cell then a new view appears by using the following code: - (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.navigationController pushViewController: detailsViewController animated: TRUE]; } By using the code above, the view is displayed correctly, but when I return back to the root table view, then the cell is still selected. I noticed, in many sdk examples, that the cell is deselected (with a nice animation) when the root view is poped pack, but I could not find the code that implemented this feature in any of the examples. I know that I can use: [tableView deselectRowAtIndexPath:indexPath animated: YES]; to implement this, but I am very curious on how these examples do it without using any code. Any ideas?

• iphone @property(retain), init(), and standards

  - by inyourcorner

  I'm new to the memory management of the iphone and had a question about standards/correctness. My header file declares: IBOutlet UITabBarController *tabBarController; @property (nonatomic, retain) UITabBarController *tabBarController; In my init() code I was doing something like the following: self.tabBarController = [[UITabBarController alloc] init]; [tabBarController release]; NSLog(@"Retain count of tbc: %d",[tabBarController retainCount]); to get the retain count back to one. Is this correct from a standardization point of view? It just looked a bit different to me, but again I'm new to this. Thanks

• In SQL how do I get the maximum value for an integer?

  - by CoffeeMonster

  Hi, I am trying to find out the maximum value for an integer (signed or unsigned) from a MySQL database. Is there a way to pull back this information from the database itself? Are there any built-in constants or functions I can use (either standard SQL or MySQL specific). At http://dev.mysql.com/doc/refman/5.0/en/numeric-types.html it lists the values - but is there a way for the database to tell me. The following gives me the MAX_BIGINT - what I'd like is the MAX_INT. SELECT CAST( 99999999999999999999999 AS SIGNED ) as max_int; # max_int | 9223372036854775807 Thanks in advance,

• Comparison tool with easy line insertion

  - by Miro Kropacek

  Back in good old days I used to use a tool for file comparison with one incredible feature -- you open file1, file2, see a difference, no magic here. But then you could insert an empty line(s) into file1 with one keyboard combo and into file2 with another keyboard combo. So you could easily adjust how are C / asm function aligned in case diff engine failed to recognize similar stuff. Of course, after the adjust (insertion / removal of one or more lines in either file) whole diff was "recalculated". I fail to find similar feature in diff, KDiff, ... I'd prefer Linux app but I'm OK with Windows app as last resort... Thanks for any hint!

• From Dictionary To File Python

  - by user3600560

  I am basically trying to write this information from my dictionary to this file. I have this dictionary named files = {} and it is for a filing system I am making. Anyhow it is always being update with new items, and I want those items to be uploaded to the file. Then if you exit the program the files are loaded back to the dictionary files = {}. Here is the code I have so far: file = {} for i in files: g = open(i, 'r') g.read(i) g.close() EDIT I want the contents of the dictionary to be written to a file. The items inside the dictionary are all stored like this: files[filename] = {filedate:filetext} where filename is the file's name, filedate is the date that the file was made on, and the filetext is the files contents.

• How to handle request/response propagation up and down a widget hierarchy in a GUI app?

  - by fig-gnuton

  Given a GUI application where widgets can be composed of other widgets: If the user triggers an event resulting in a lower level widget needing data from a model, what's the cleanest way to be able to send that request to a controller (or the datastore itself)? And subsequently get the response back to that widget? Presumably one wouldn't want the controller or datastore to be a singleton directly available to all levels of widgets, or is this an acceptable use of singleton? Or should a top level controller be injected as a dependency through a widget hierarchy, as far down as the lowest level widget that might need that controller? Or a different approach entirely?

• Drupal, template.php where do the $form names come from ?

  - by Patrick

  hi, I want to customize my Drupal back-end forms. I'm using template.php file.. i.e. $form['menu']['#collapsed'] = true; $form['author']['#collapsed'] = true; $form['buttons']['#weight'] = 100; But I was wondering from where the section names (menu, author, buttons), come from. (They are not id or classes in html code, so I guess there is an index with all names stored somewhere. Where can I get the complete list of section names ? Furthermore, I've added a taxonomy-super-select-checkboxes section by installing the module. How can I refer to this section, to make the field not collapsed. thanks

• Merging Brach into Trunk...

  - by jimbo

  Now I know this has been asked a few times, but i'm still not getting it... I use Versions which is doing a great job, I am also using beansalk and they are working nicely together. However, I have been working on a branch of the trunk (sandbox) which I now want to merge back into the trunk. Versions can't do this, so it's into Terminal. Sandbox is reversion 256 and the Trunk (because of a few other amends) is 255. Any help on this would be great, and read a few bits, but still a little lost...

• Screenflow based application in Adobe Flex/Flash

  - by iceman

  I'm searching for some code samples for my Flash application. The app is based on screen-flows , i.e each screen is defined with some visual elements with some buttons which have async events associated with them(consuming web services basically). The buttons also have functionality to go back and forth between screens and jump to any screen. I want to define all of the visual elements and the functionality of the events in a XML file. Thus the model, view and controller are all in the XML. Does any framework allow this like Pure MVC? Where can I find some examples of this kind of functionality that I want?

• reading partially from sockets

  - by nomad.alien

  I'm having a little test program that sends a lot of udp packets between client-server-client (ping/pong test). The packets are fixed size on each run(last run is max allowable size of udp packet) I'm filling the packets with random data except for the beginning of each packet that contains the packet number. So I'm only interested to see if I receive all the packets back at the client. I'm using sendto() and recvfrom() and I only read the sizeof(packet_number) (which in this case is an int). What happens to the rest of the data? Does it end up in fairyland (gets discarded)? or does the new packet that arrives gets appended to this "old" data? (using linux)

• Django: HTTPS for just login page?

  - by Mark

  I just added this SSL middleware to my site http://www.djangosnippets.org/snippets/85/ which I used to secure only my login page so that passwords aren't sent in clear-text. Of course, when the user navigates away from that page he's suddenly logged out. I understand why this happens, but is there a way to pass the cookie over to HTTP so that users can stay logged in? If not, is there an easy way I can use HTTPS for the login page (and maybe the registration page), and then have it stay on HTTPS if the user is logged in, but switch back to HTTP if the user doesn't log in? There are a lot of pages that are visible to both logged in users and not, so I can't just designate certain pages as HTTP or HTTPS.

• MySQL : Calculate business day difference between two dates column

  - by yokoyoko

  My sql query returns back two columns, first column is "date created" and second column is "date updated", first column has a prior timestamp with respect to second column. I need to add a third column which can display business day hrs (9:00am to 5:00pm) response i.e. if date created is 2012-01-01 09:00:20 and "dated updated" is 4:00pm same day then third column should display 7 hrs If date created is 2012-01-01 16:00:20 (4:00pm) and "date updated" is 10:00m on 2012:01:02 (2nd Jan) then third column should display 2 hrs. It should exclude Saturday and Sunday. Can you please suggest appropriate SQL query for this.
