  • How to find the only UILabel in a view and hide it?

    - by tarnfeld
    I am adding a UILabel as a subview to a UIView and sometime later I want to hide it. It is assigned to a variable but I don't think setting the variables property Hidden after it's been added to the view will work (well it doesn't seem to anyway). Is there a way to loop through the subviews in a view and then find the one that has a specific tag or is of type UILabel that I could then remove?

  • Haskell: Gluing a char and a list together?

    - by Vincent
    So I have this code here: toWords :: String - [a] toWords "" = [] toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest The "toWords" function should simply remove all spaces and return a list with all the words. But I keep getting this error: test.hs:5:18: Couldn't match expected type a' against inferred typeChar' `a' is a rigid type variable bound by the type signature for `toWords' at test.hs:1:22 In the first argument of `(:)', namely `nr1' In the expression: nr1 : toWords rest In the definition of `toWords': toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest Failed, modules loaded: none.

Usage: myapp [OPTION] [DIRECTORY] Options: -a Option A -b Option B How do I declare and access the DIRECTORY variable? Thank you.

  • What is the best file system to use for a second hard drive when dual booting between WinXP and Win7

    - by Corey
    I am dual booting for legacy reasons, and I have a 2nd internal drive that I would like to use from both XP and 7. Should I go with the standard NTFS? (will the secuirty features be an issue, with different SIDs from the different users) Should I go with FAT32? Should I try out the new exFAT? Also, I curently have two of my 3 drives as "dynamic disks" and 1 spaned volume created on them. (i did this from XP) Win7 can see them/it fine. Is this an ok thing to do?

  • How do I create a loop based off this array?

    - by dmanexe
    I'm trying to process this array, first testing for the presence of a check, then extrapolating the data from quantity to return a valid price. Here's the input for fixed amounts of items, with no variable quantity. <input type="checkbox" name="measure[<?=$item->id?>][checked]" value="<?=$item->id?>"> <input type="hidden" name="measure[<?=$item->id?>][quantity]" value="1" /> Here's the inputs for variable amounts of items. <input type="checkbox" name="measure[<?=$item->id?>][checked]" value="<?=$item->id?>"> <input class="item_mult" value="0" type="text" name="measure[<?=$item->id?>][quantity]" /> So, the resulting array is multidimensional. Here's an output: Array ( [1] => Array ( [quantity] => 1 ) [2] => Array ( [quantity] => 1 ) [3] => Array ( [quantity] => 1 ) ... [14] => Array ( [checked] => 14 [quantity] => 999 ) ) Here's the loop I'm using to take this array and process items checked off the form in the first place. I guess the question essentially boils down to how do I structure my conditional statement to incorporate the multi-dimensional array? foreach($field as $value): if ($value['checked'] == TRUE) { $query = $this->db->get_where('items', array('id' => $value['checked']))->row(); #Test to see if quantity input is present if ($value['quantity'] == TRUE) { $newprice = $value['quantity'] * $query->price; $totals[] = $newprice; } #Just return the base value if not else { $newprice = $query->price; $totals[] = $newprice; } } else { } ?> <p><?=$query->name?> - <?=money_format('%(#10n', $newprice)?></p> <? endforeach; ?>

    Hi all, I have a variable of type List<RelationHeader>. Now I want to copy all the elements in this list to a new list, but I want to actually copy all the members by value (clone them). Is there a quick command to do this, or do I need to iterate over the list and copy them one at a time?

  • Clean way to assign value unless empty

    - by atmorell
    Hello, I often need to assign a variable, if the source value is set. So far I have done it like this: filters[:red] = params[:search][:red] unless params[:search][:red].nil? This works but looks a bit clumsy. There must be a more DRY way of getting this result. Any suggestions? Best regards. Asbjørn Morell.

  • Combine several locations with regex in nginx

    - by AlexAtNet
    I dynamic number of Joomla installations in subfolders of the domain. For example: http://site/joomla_1/ http://site/joomla_2/ http://site/joomla_3/ ... Currently I have the follwing config that works: index index.php; location / { index index.php index.html index.htm; } location /joomla_1/ { try_files $uri $uri/ /joomla_1/index.php?q=$uri&$args; } location /joomla_2/ { try_files $uri $uri/ /joomla_2/index.php?q=$uri&$args; } location ~ \.php$ { fastcgi_pass unix:/var/run/php5-fpm/joomla.sock; ... } I'm trying to combine joomla_N rules in one: location ~ ^/(joomla_[^/]+)/ { try_files $uri $uri/ /$1/index.php?q=$uri&$args; } but server starts to return index.php as is (does not call the php-fpm). It looks like the nginx stops the processing of the regex rules after the first match. Is there any way to combine this rules with something like regex?

  • How to generate changelog: git log since last Hudson build?

    - by takeshin
    I'm using Phing to do post build tasks in Hudson. I want to generate changelog containing all commits since last successful Hudson build. But looks like neither Hudson nor Git plugin for Hudson does not provide %last_build_time% variable. This would be satisfying solution, (but how to get the time?): git log --pretty="%s" --since="%last_build_time%" The only way I see for now is extracting it from the job xml file, but I do not know if it is possible with Phing. How do you generate your change logs?

  • Android Assets No Value Read?

    - by BahaiResearch.com
    AssetManager assets = myContext.getAssets(); String[] files = assets.list("MyFolder"); InputStream myInput = assets.open("MyFolder/" + files[0]); int i = myInput.read(); in this case 'i' is -1 meaning nothing read. Why would nothing be there if the file is there, the variable 'files' has the file as well. Do I need to do anything to the file I put into the Assets folder in get it to be readable?

  • javascript instanceof get type from string name

    - by dcp
    Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?

  • How to set up Nginx as a caching reverse proxy?

    - by Continuation
    I heard recently that Nginx has added caching to its reverse proxy feature. I looked around but couldn't find much info about it. I want to set up Nginx as a caching reverse proxy in front of Apache/Django: to have Nginx proxy requests for some (but not all) dynamic pages to Apache, then cache the generated pages and serve subsequent requests for those pages from cache. Ideally I'd want to invalidate cache in 2 ways: Set an expiration date on the cached item To explicitly invalidate the cached item. E.g. if my Django backend has updated certain data, I'd want to tell Nginx to invalidate the cache of the affected pages Is it possible to set Nginx to do that? How?

  • Queue management in Rails

    - by Cyborgo
    Hi, I am planning to have something like this for a website that is on Ruby on Rails. User comes and enters a bunch of names in a text field, and a queue gets created from all the names. From there the website keeps asking more details for each one from the queue until the queue finishes. Is there any queue management gem available in Ruby or I have to just create an array and keep incrementing the index in session variable to emulate a queue behaviour?
