  • How do to check to see if the user has a Google account.

    - by skrat
    Is there any safe way to detect, on a web page, client side (JS), whether user has an Google/Yahoo/Live/? account? I know about some suspicious ways to do this by styling visited links and then sneaking on computed style attribute, but it's more of a hack, Mozilla and maybe other are planning to crack down on this, as it might be abused. But I need this to allow users more integration with their identity providers, like: Have a Google account? ~ load contacts for sharing from Google Contacts API Have an Yahoo account? ~ load contacts for sharing from Yahoo Contacts API none of the above? show no link I don't want to provide all these options to all visitors, would be nice if I can detect the account, and provide integration only in that case.

  • How can I check if a Perl array contains a particular value?

    - by Mel
    I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array. I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams. I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.

  • How can I check with a regex that a string contains only certain allowed characters?

    - by Camran
    I need a special regular expression, have no experience in them whatsoever so I am turning to you guys on this one: I need to validate a classifieds title field so it doesn't have any special characters in it, almost. Only letters and numbers should be allowed, and also the swedish three letters å, ä, ö, and also not case sensitive. Besides the above, these should also be allowed: The "&" sign. Parenthesis sign "()" Mathematical signs "-", "+", "%", "/", "*" Dollar and Euro signs One accent signed letter: "é". //Only this one is required Double quote and singel quote signs. The comma "," and point "." signs Thanks

  • How do I check if a scalar has a compiled regex in it with Perl?

    - by Robert P
    Let's say I have a subroutine/method that a user can call to test some data that (as an example) might look like this: sub test_output { my ($self, $test) = @_; my $output = $self->long_process_to_get_data(); if ($output =~ /\Q$test/) { $self->assert_something(); } else { $self->do_something_else(); } } Normally, $test is a string, which we're looking for anywhere in the output. This was an interface put together to make calling it very easy. However, we've found that sometimes, a straight string is problematic - for example, a large, possibly varying number of spaces...a pattern, if you will. Thus, I'd like to let them pass in a regex as an option. I could just do: $output =~ $test if I could assume that it's always a regex, but ah, but the backwards compatibility! If they pass in a string, it still needs to test it like a raw string. So in that case, I'll need to test to see if $test is a regex. Is there any good facility for detecting whether or not a scalar has a compiled regex in it?

  • Keep data with specific value on top when sorting a gridview

    - by aspNetAficionado
    Hi i have a gridview with information about documents: name, document type (policy, guidelines, forms, etc), category, etc. I want to sort the gridview alphabetically (name) and by document type, but always having the 'policy' above the other document types when document name is the same. How do I do that? eg If I do sort by DocumentName, DocumentType ('policy' maybe not be the first one in the list) but if I do sort by DocumentType , DocumentName (I would get for example all guidelines first in alphabetical order, then procedures, then policies, etc)

  • Best way to check for nullable bool in a condition expression (if ...)

    - by FireSnake
    I was wondering what was the most clean and understandable syntax for doing condition checks on nullable bools. Is the following good or bad coding style? Is there a way to express the condition better/more cleanly? bool? nullableBool = true; if (nullableBool ?? false) { ... } else { ... } especially the if (nullableBool ?? false) part. I don't like the if (x.HasValue && x.Value) style ... (not sure whether the question has been asked before ... couldn't find something similar with the search)

  • Mongodb update: how to check if an update succeeds or fails?

    - by zmg
    I think the title pretty much says it all. I'm working with Mongodb in PHP using the pecl driver. My updates are working great, but I'd like to build some error checking into my funciton(s). I've tried using lastError() in a pretty simple function: function system_db_update_object($query, $values, $database, $collection) { $connection = new Mongo(); $collection = $connection->$database->$collection; $connection->$database->resetError(); //Added for debugging $collection->update( $query, array('$set' => $values)); //$errorArray = $connection->$database->lastError(); var_dump($connection->$database->lastError());exit; // Var dump and /Exit/ } But pretty much regardless of what I try to update (whether it exists or not) I get these same basic results: array(4) { ["err"]=> NULL ["updatedExisting"]=> bool(true) ["n"]=> float(1) ["ok"]=> float(1) } Any help or direction would be greatly appreciated.

  • Getting a date value in a postgres table column and check if it's bigger than todays date

    - by Roland
    I have a Postgres table called clients. The name column contains certain values eg. test23233 [987665432,2014-02-18] At the end of the value is a date, I need to compare this date, and return all records where this specific date is younger than today I tried select id,name FROM clients where name ~ '(\d{4}\-\d{1,2}\-\d{1,2})'; but this isn't returning any values. How would I go about to achieve the results I want?

  • Rails: Is there a way to check for incomplete JPG file upload?

    - by user206481
    I have a Rails app that processes and serves up jpg files that were uploaded via FTP. On several occasions the FTP process was disconnected and left many incomplete .jpg files. I was surprised to see that the incomplete jpgs behave as normal jpg files in my app even tho they have incomplete image data. I have since implemented a more robust FTP process where the uploaded file is initially *.tmp and gets renamed to .jpg after an FTP success code is received. My problem is, I still have all of these incomplete jpg files on the server and can't figure out how to programmatically weed them out. I can actually display them in a view without generating any errors, but there is only a partial image there. I tried RMagick but they all successfully load (using Image.read) and report the valid x & y resolutions. I have so far not been able to determine a way to programmatically differentiate between an incomplete and complete jpg uploaded image. Any ideas?

  • jQuery: What listener do I use to check for browser auto filling the password input field?

    - by Jannis
    Hi, I have a simple problem that I cannot seem to find a solution to. Basically on this website here: http://dev.supply.net.nz/vendorapp/ (currently in development) I have some fancy label animations sliding things in and out on focus & blur. However once the user has logged in once the browser will most likely remember the password associated with the users email address/login. (Which is good and should not be disabled.) However I run into issues triggering my label slide out animation when the browser sets the value on the #password field automatically as the event for this is neither focus nor blur. Does anyone know which listener to use to run my function when the browser 'auto fills' the users password? Here is a quick screenshot of the issue:

  • Fastest algorithm to check if a number is pandigital?

    - by medopal
    Pandigital number is a number that contains the digits 1..number length. For example 123, 4312 and 967412385. I have solved many Project Euler problems, but the Pandigital problems always exceed the one minute rule. This is my pandigital function: private boolean isPandigital(int n){ Set<Character> set= new TreeSet<Character>(); String string = n+""; for (char c:string.toCharArray()){ if (c=='0') return false; set.add(c); } return set.size()==string.length(); } Create your own function and test it with this method int pans=0; for (int i=123456789;i<=123987654;i++){ if (isPandigital(i)){ pans++; } } Using this loop, you should get 720 pandigital numbers. My average time was 500 millisecond. I'm using Java, but the question is open to any language.
