• How to get Field Labels from PIMItem - Blackberry

  - by Taha

  How can we get Field Labels from PIMItem. The following code is with PIMList String label = pimList.getAttributeLabel(blackBerryContact.getAttributes(Contact.TEL, i)); But i have PIMItem. There is a method PIMItem.getPIMList() which returns null for me in the code below. THE API at http://www.blackberry.com/developers/docs/5.0.0api/index.html says "getPIMList() Gets the PIMList associated with this item." Below is sample code that i am trying to achive - // Load the address Book and allow the user to select a contact BlackBerryContactList contactList = (BlackBerryContactList) PIM.getInstance().openPIMList(PIM.CONTACT_LIST,PIM.READ_ONLY); PIMItem userSelectedContact = contactList.choose(); // Now get the Field labels for contact numbers for userSelectedContact

• SQL Compact Edition database corruption

  - by jdv

  Hi, Our product is using MS SQL Compact Edition on a Windows machine (laptop). It's basically a metadata index for files we have on the filesystem. Recently we have seen databases getting corrupted. This happens when the machine is very busy moving files around and has to do a tiny bit of database changes at the same time. I was somewhat shocked that was at all possible. It was my expectation that the database would stay coherent whatever the circumstances. Of course we are doing something wrong. Things we have checked so far are: Use of only one db connection per thread specify the maximum size when opening the database The database is accessed only by one application, a .net based windows service. Are there other gotcha's?

• Sparse Array in C! How accomplish it? Can I alloc only parts of an array?

  - by drigoSkalWalker

  Hi guys! The first question is: "How I do a simple sparse array in C (with one dimension only)?" {with my own hands, without libraries.} And the last one: "Can I allocate only parts of an array?" like *array; then use malloc to allocate some mem for this; so, We free the index that we don't want. Can I do it? Thanks so much!

• Accessing cookies in php which are set in java web application

  - by user866937

  I am setting a cookie at the domain level on encrypted connection in Java web application running on tomcat and I would like it to be accessible in a php web application running on a same domain but different subdomain. Java web application running on https://javaapp.mycompany.com php web application running on https://phpapp.mycompany.com/subpath/index.php From java, I am setting the cookie with following parameters: Domain: .mycompany.com Send For: Encrypted connections only Expires: After 2 months Path: /subpath Name: __C Value: 1 Dumping all the cookies from my php web application running on https, I do not see any cookies getting dumped by the php web application. Whereas if I set the cookies in Java for any type of connection, only then php web application is able to see them if I run the php app on http instead of https. I believe php web app should be able to retrieve then cookies set for https only and for particular domain and all immediate sub-domains. What am I doing wrong here? Thanks in advance for the help.

• MYSQL Inserting rows that reference main rows.

  - by Andrew M

  I'm transferring my access logs into a database. I've got two tables: urlRequests id : int(10) host : varchar(100) path: varchar(300) unique index (host, path) urlAccesses id : int(10) request : int(10) <-- reference to urlRequests row ip : int(4) query : varchar(300) time : timestamp I need to insert a row into urlAccesses for every page load, but first a row in urlRequests has to exist with the requested host and path so that urlAccesses's row can reference it. I know I can do it this way: A. check if a row exists in urlRequests B. insert a row in urlRequests if it needs it C. insert a row into urlAccesses with the urlRequests's row id referenced That's three queries for every page load if the urlRequests row doesn't exist. I'm very new to MySQL, so I'm guessing that there's a way to go about this that would be faster and use less queries.

• How to change ScrollView's position after touch?

  - by Matt

  I'm trying to make a ScrollView with a list of numbers in it that the user can select from. After the user touches and scrolls, after the finger is lifted I want the scroll to "snap" to the item in the middle of the ScrollView and give me the output. My ScrollView contains a vertical linear layout with TextView objects in it. The ScrollView's vertical size is about 60sp. I think this would involve the ScrollView.onTouch with a ACTION_UP, but I don't know how to use it. Also, is there a way to get an item's index or value based on a position in the list? Thanks!

• ZF: Url View Helper Acting Strangely

  - by moteutsch

  I have the following route defined: $route = new Zend_Controller_Router_Route( 'users/:id', array( 'controller' => 'users', 'action' => 'profile', 'id' => '' ) ); When I am on the page via the shortened URL (localhost/users/someuser), the URLs defined in the layout file all link to "localhost/users". Here is the code in the layout: <li><a href="<?php echo $this->url(array('controller' => 'index'), null, true); ?>">Home</a></li> <li><a href="<?php echo $this->url(array('controller' => 'search'), null, true); ?>">Search</a></li> <!-- etc. --> How can I fix the code so that the links in the layout file point to the correct URLs?

• dynamic access magic constants in php

  - by Radu

  Hello, Is there a way to shortcut this: function a($where){ echo $where; } function b(){ a(basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__); } to something like this: define("__myLocation__", ''.basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__.''); function a($where){ echo $where; } function b(){ a(__mYLocation_); } I know that this cannot be done with constants (is just an theoretical example), but I can't find a way to shorthen my code. If a use a function to get my line it will get the line where that function is not the line from where the function was called. I usualy call a function that prints directly to the log file, but in my log I need to know from where the function was called, so i use basename(__FILE__).'::'.__FUNCTION__.'()::'.__LINE__ this will print something like: index.php::b()::6 It is a lot of code when you have over 500 functions in different files. Is there a shorten or better way to do this? Thank you.

• Jquery how to test if current hovered div is eq(x)

  - by j-man86

  Hi all! I am trying to create a jQuery hover function that will highlight a different section of the page depending on what number EQ (index position number) the div is. $('#photoContent div').hoverIntent(function () { if( $(this).filter(':lt(5)') ) { $('#photoSidebar').find('p:eq(0)').addClass('currentPhoto'); } if( $(this).filter(':gt(5)') ) { $('#photoSidebar').find('p:eq(1)').addClass('currentPhoto'); } }, function () { $('#photoSidebar').find('p').removeClass('currentPhoto'); }); The above code obviously does not work, but the concept/functionality is what I'm going for. Thanks for your help!

• Link redirects to "show" action instead of the indicated in routes.rb

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.4 and I'd like to have a link that executes an action when clicked. The relevant part of the routes.rb file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' My view(it's the model's index page) looks like this: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> And my controller looks like this: def search_filter_relevance raise params.inspect unless params[:announcements].nil? or params[:announcements].empty? @announcements = params[:announcements].order_by_featured end end The problem is that when I click the link I get an error due to some null value in the Show action! I'm not accessing that action at all...why is executing it?

• Web based interface for open SSL client certificates

  - by Felix

  Hi there! We are currently developing a apache2-based web application and want to invite some beta testers to give it a try. To be on the safe side, access should be provided by individual browser certificates (.p12) which are issued using a (fake) CA. Our users should be passing a complete register/login process and some of them will be granted administrative privileges within the application. That's why a preceding simple web-based authentication won't be sufficient. Atm, I using a serverside shellscript to generate the certificates each time. Do you know about a small, web-based tool to simplify the process of generating / revoking those certificates? Maybe an overview of the CA's index.txt plus the option to revoke a cert and a link to download them directly?

• Tag Cloud Data Backend

  - by Waldron

  I want to be able to generate tag clouds from free text that comes from any number of different sources. For clarity, I'm not talking about how to display a tag cloud once the critical tags/phrases are already discovered, I'm hoping to be able to discover the meaningful phrases themselves... preferable on a PHP/MySQL stack. If I had to do this myself, I'd start by establishing some kind of index for words/phrases that gives a "normal" frequency for any word/phrase. eg "Constantinople" occurs once in every 1,000,000 words on average (normal frequency "0.000001"). Then as I analyze a body of text, I'd find the individual words/phrases (another challenge!), find frequencies of each within the input, and measure against the expected freqeuncy. Words that have the highest ratio against expected frequency get boosted priority in the cloud. I'd like to believe someone else has already done this, WAY better than I could hope to, but I'll be damned if I can find it. Any recommendations??

• How might one detect the first run of a program?

  - by Julian H. Lam

  In my web application, users can download a .tar.gz archive containing the app files. However, because the MySQL database won't have been configured then, the user needs to run the install script located in ./install. I "catch" the user upon first run of the app by checking to see if the ./install directory exists. If so, the index.php page redirects the user to the install script. However, I was wondering if there were a more elegant way to "catch" a user upon first-run of a program. Someone on IRC suggested the web-server create a file .installed upon completion, but because the web server might not have write privileges to the web root directory, I can't rely on that. How would you go about solving this problem, or is my solution workable?

• How do I change the list using mutable lists in Racket or Scheme?

  - by exOne

  I need your help Can anyone help me? first question This procedure should modify each element which’s index in the list is even. The value of the element should be equal to the new-element. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-indices number-list 10) The new list: 1 10 8 10 43 10 78 second question This problem is the extended version of Question 1. (modify-even-odd-indices my-list new-element modification-type) This procedure should modify each element according to the modification-type. The modification-type can be even or odd. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-odd-indices number-list 10 ‘even’) The new list: 1 10 8 10 43 10 78 (modify-even-odd-indices number-list 10 ‘odd’) The new list: 10 56 10 1 10 9 10

• Fast image coordinate lookup in Numpy

  - by victor

  I've got a big numpy array full of coordinates (about 400): [[102, 234], [304, 104], .... ] And a numpy 2d array my_map of size 800x800. What's the fastest way to look up the coordinates given in that array? I tried things like paletting as described in this post: http://opencvpython.blogspot.com/2012/06/fast-array-manipulation-in-numpy.html but couldn't get it to work. I was also thinking about turning each coordinate into a linear index of the map and then piping it straight into my_map like so: my_map[linearized_coords] but I couldn't get vectorize to properly translate the coordinates into a linear fashion. Any ideas?

• A faster alternative to Pandas `isin` function

  - by user3576212

  I have a very large data frame df that looks like: ID Value1 Value2 1345 3.2 332 1355 2.2 32 2346 1.0 11 3456 8.9 322 And I have a list that contains a subset of IDs ID_list. I need to have a subset of df for the ID contained in ID_list. Currently, I am using df_sub=df[df.ID.isin(ID_list)] to do it. But it takes a lot time. IDs contained in ID_list doesn't have any pattern, so it's not within certain range. (And I need to apply the same operation to many similar dataframes. I was wondering if there is any faster way to do this. Will it help a lot if make ID as the index? Thanks!
