• CSS backgroung color is differnt in IE vs FF

  - by Mike Ozark

  In FF it works like intended (puts light transparent ribbon on the bottom of the image for caption). But in IE it's totally black (caption does show) .caption { z-index:30; position:absolute; bottom:-35px; left:0; height:30px; padding:5px 20px 0 20px; background:#000; background:rgba(0,0,0,.5); width:300px; font-size:1.0em; line-height:1.33; color:#fff; border-top:1px solid #000; text-shadow:none; }

• How to get the set events of a control?

  - by Jack

  It's possible via C# code get an list of methods/delegates that was set to Control? let me explain better.. For example. Assuming some definitions like this: foo.Click += (a, b) => { ... } //.. foo.Click += (A,B) => { ... } And a megic method: var baa = foo.GetEvents("Click"); Returns baa[0] points to (a, b) => { ... } baa[1] points to (A,B) => { ... } My scenery: I make and add dynamically event to some controls inside a loop. I want depending to a boolean value a event of control of index one,will removed by using control.Click -= baa[1] or something like this. I hope this is clear for your. Thanks in advance.

• CodeIgniter won't run in a subdirectory

  - by Tim Piele

  I have a CodeIgniter install running in our root web directory that I copied into a subdirectory called /dev... I edited the config/config.php file to reflect the change so it is now like this: $config['base_url'] = 'http://mysite.com/dev'; $config['sbase_url'] = 'https://mysite.com/dev'; $config['default_email'] = '[email protected]'; $config['site_url'] = 'http://mysite.com/dev'; This is my .htaccess file: <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php/$1 [L] </IfModule> When I hover over any links on the site they are correct, for example the contact us page link reads www.mysite.com/dev/contact but when I click any of the links I get a 404 error... Is there something common I am missing?

• Row for each hour even if there is no record

  - by peku33

  I've got a trouble with creating mysql Query. My PHP script executes this query on each run: INSERT INTO Executes SET UserIp='%s' (%s is user IP) Executes table is: ExecuteId UNSIGNED BIGINT AI PRIMARY Date TIMESTAMP DEFAULT CURRENT_TIMESTAMP INDEX UserIp CHAR(24) ... | Some Columns I want to retrive number of Executes in each hour. The most obvious solution would be: SELECT COUNT(*) as ExecutesNum, DATE(Date) as D, HOUR(Date) as H GROUP BY D, H And it works, BUT it does not create rows for hours where there were no executes. What should I modify to get result like: 1 | 2012-09-01 | 14 **0 | 2012-09-01 | 15** 11 | 2012-09-01 | 16 1 | 2012-09-01 | 17

• MySQL pivot tables - covert rows to columns

  - by user2723490

  This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

• Creating a CD auto-start dialog

  - by emilyshaun

  For me, compact discs and these customized auto-start dialogs are somewhat outdated and waste... However, I have to create such a dialog as an index for a CD consisting of a few PDF files. Making one to work on Microsoft Windows is quite easy. As there might be users from different platforms (Unix, Apple,...), the question raises how to offer them such a (auto-starting) dialog as well. Java is of course an option, but I think it's overloaded and naturally too slow for this purpose. Now, I think of a single webpage that will appear in the local browser. Using all these web standards this could a very creative, light-weight approach working on most systems. Do you see any problems that might occur here? Probably, there is a different and more elegant solution to this issue?

• How to allow three optional parameters in the URL by .htaccess?

  - by eij

  I have http://example.com and a PHP routing class that checks if some URL exists. I want to make a new route, which is: http://example.com/foo/bar/123 but as long as I open it, the Apache redirects me to an error page. So I'm using a .htaccess. The code is: RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*) /index.php [L] and it works, as long as I use http://example.com/foo, but once I add some other parameters, it redirects me to an error. I'm guessing that the rewrite code is wrong. Is it wrong? If yes, could you suggest me the good one? If no, where the problem could be located?

• IIS, Apache, and header()

  - by MetalAdam

  I'm working on migrating a website from an external server (running Apache) to a local server (running IIS), and have come across an issue that I can't seem to resolve. The site is using a custom Joomla plugin that grabs some graphics stored in a mysql database (for e.g. http://www.norfolktourism.ca/index.php?option=com_bdirectory&task=image&cid=191). However, when I migrate the site to the local server, the images are broken. Upon further exploration, I've discovered that somehow, when ran on the local server, their seems to whitespace (as in a new line) gets processed before the header() function is processed, hence breaking the image (however, I don't get an error - just a broken image). I'm absolutely baffled as to what the issue may be, as the code works fine on the external Apache server. Would anyone have any suggestions on possible resolutions?

• Is it faster to count down that it is to count up?

  - by Bob

  Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

• Mysql with innodb and serializable transaction does not (always) lock rows

  - by Tobias G.

  Hello, I have a transaction with a SELECT and possible INSERT. For concurrency reasons, I added FOR UPDATE to the SELECT. To prevent phantom rows, I'm using the SERIALIZABLE transaction isolation level. This all works fine when there are any rows in the table, but not if the table is empty. When the table is empty, the SELECT FOR UPDATE does not do any (exclusive) locking and a concurrent thread/process can issue the same SELECT FOR UPDATE without being locked. CREATE TABLE t ( id INT NOT NULL AUTO_INCREMENT PRIMARY KEY, display_order INT ) ENGINE = InnoDB; SET TRANSACTION ISOLATION LEVEL SERIALIZABLE; START TRANSACTION; SELECT COALESCE(MAX(display_order), 0) + 1 from t FOR UPDATE; .. This concept works as expected with SQL Server, but not with MySQL. Any ideas on what I'm doing wrong? EDIT Adding an index on display_order does not change the behavior.

• How should I set up UITableViewCell subclasses with UIControls in them?

  - by GeneralMike

  I have a dynamically generated UITableView (so I have to use prototype cells, not static cells) with many cells on it. Each cell will have a UILabel on it. Additionally, each cell will also have at least one UIControl (as of right now, it could be a UITextfield or a UISegmentedControl, but I want to keep it flexible in case I add something else in the future). I'm going to need to be able to send the text in that label, and get either the text in the textfield, or the title of the selected segment index, etc. For the cells with multiple controls, I'm going to have to also let it know what control I'm interested in for that call. What would be the best way to set this up?

• how do indices in mysql tables (MyISAM) work?

  Few basic doubts I have: 1. Is primary key column automatically indexed? 2. What should be criteria to select index column? 3. When should I club multiple columns? 4. Does MyISAM or InnoDB has any affect on this? 5. Are they really required, specially in case if primary key column is automatically indexed? Thanks.

• Possible to get jquery .serializeArray() values out by key name?

  - by chobo2

  Hi I am using the jquery .serializeArray() function and I send it to the server and that works all good.However I need to update a couple things on the client side that are serialized. So instead of doing another selector on the textbox I want to just grab it out of the serialized array. I am not sure how to do this Product=Test&Qty=50 So say if I have something like this. I can I do something like this var sendFormData = form.serializeArray(); var val = sendFormData["Product"].value; but this seems not to work. I only can get it to work when I do something like this var sendFormData = form.serializeArray(); var val = sendFormData[0].value; I really don't want to do it by index since that means if the order changes the values could be all wrong. If you could do it by like keyname then that would not be a problem.

• Removing an element from an array (PHP)

  - by morpheous

  I want to remove an element from a PHP array (and shrink the array size). Just looking at the PHP docs, it seems this can be done using array_slice() and array_merge() so I am guessing (off the top of my head) that some combination of array_merge() and array_slice will work. However, array_slice() requires an index (not a key), so I'm not sure how to quickly cobble these functions together for a solution. Has anyone implemented such a function before?. I'm sure it must be only a few lines long, but I cant somehow get my head around it (its been one of those days) ... Actually, I just came up with this cheesy hack when writing up this question.... function remove_from_array(array $in, value) { return array_diff($in, (array)$value); } too ugly? or will it work (without any shocking side effects)?

• Clojure: find repetition

  - by demi

  Let we have a list of integers: 1, 2, 5, 13, 6, 5, 7 and I want to find the first number has a duplicate before it and return a vector of two indices, In my sample, it's 5 at [2, 5]. What I did so far is loop, but can I do it more elegant, short way? (defn get-cycle [xs] (loop [[x & xs_rest] xs, indices {}, i 0] (if (nil? x) [0 i] ; Sequence is over before we found a duplicate. (if-let [x_index (indices x)] [x_index i] (recur xs_rest (assoc indices x i) (inc i)))))) No need to return number itself, because I can get it by index and, second, it may be not always there.

• Programmatic gradient stops with Javascript

  - by TomcatExodus

  Working with Javascript (jQuery), given 2 color values (2033ff and 3300a0 for example) how can I determine certain gradient stops between them? Reason being is, I intend on using an array of color values: 0 => '000000' 8400 => 'f0ff00' 44000 => '2033ff' 68400 => '3300a0' There being 86400 seconds in a day, 12:00AM maps to 0, and 11:59PM maps to 86399. As time passes, the background color of a specified element changes to the appropriate color in gradient list via window.setInterval(function(e){ ... }, 1000). For example 2:32:11PM = 52331, which from the example would be somewhere between 2033ff and 3300a0. I don't need to populate the array with the values (unless that would be easier) but instead use the index and value as references.

• CakePHP ACL use case(s)

  - by Jonathan

  I have got a simple web app in development, i want to establish a couple of user groups; Admin, Doctors & Patients. Each group would have their access restricted to particular controller actions rather than individual content. So for example, Doctors can view patient records (index & view actions), but cannot delete them. Usually i would create a groups model, and assign the various users to a group. And filter in the beforeFilter() method to determine if the user has access. But if ACL can do the job, why right the code, right? Thanks

• Need to sync two lists with atrribute time, but times aren't equal

  - by virgula24

  I gonna try to describe my problem the best i can. I have two lists, one with audio frames and other with color frames (not relevant). Both of them have timestamps, they were captured at the same moment but at different instants. So, i have like this: index COLOR AUDIO 0 841 846 1 873 897 2 905 948 3 940 1000 the frames start at high numbers because they were captured and then trimmed to specific parts, but im shot, frame 0 is synced with only 5ms apart(timestamp in ms). On every case i have, the audio frames count is less than the color count. I need to make them have the same count. The stating frames may be coloraudio, color

• PHP - Get values from Array

  I am trying to get a record from a database using an sql lookup (sql1). This then returns as an array which is fine, but I need to use part of the array for my next stage. $opt=get_records_sql($sql1); //Diags for SQL content print_object($opt); $n = count($opt); if (empty($opt)) { echo 'No options selected'; } else { $optno = $opt["subjectid"]; // Diags of $optno echo '<br>$optno = '.$optno; As you can see, I tried to use this: $opt["subjectid"] as subjectid is the fieldname that I am trying to access and I was under the impression that this was correct for accessing an array, but I get the following error: Notice: Undefined index: subjectid Array contents: Array ( [1] => stdClass Object ( [uname] => JHollands06 [tutor] => M LSt [subjectid] => 1 [year] => 2010 [optid] => 1 ) )

• Why isn't INT more efficient than UNIQUEIDENTIFIER (according to the execution plan)?

  - by ck

  I have a parent table and child table where the columns that join them together are the UNIQUEIDENTIFIER type. The child table has a clustered index on the column that joins it to the parent table (its PK, which is also clustered). I have created a copy of both of these tables but changed the relationship columns to be INTs instead, have rebuilt the indexes so that they are essentially the same structure and can be queried in the same way. When I query for a known 20 records from the parent table, pulling in all the related records from the child tables, I get identical query costs across both, i.e. 50/50 cost for the batches. If this is true, then my giant project to change all of the tables like this appears to be pointless, other than speeding up inserts. Can anyone provide any light on the situation? EDIT: The question is not about which is more efficient, but why is the query execution plan showing both queries as having the same cost?
