  • Searching within an array of strings...

    - by SoLoGHoST
    Ok, I'm feeling retarded here, I have a string like so: $string = 'function module_testing{'; or it could be like this: $string = 'function module_testing'; And than I have an array of strings like so: $string_array = array('module_testing', 'another_function', 'and_another_function'); Now, is there some sort of preg_match that I can do to test if any of the $string_array values are found within the $string string at any given position? So in this situation, there would be a match. Or is there a better way to do this? I can't use in_array since it's not an exact match, and I'd rather not do a foreach loop on it if I can help it, since it's already in a while loop. Thanks :)

  • Convert Military time to string representation

    - by RRUZ
    I have an column declarated as int (called HourMil) wich store the time in military format. i need convert this values to an formated string (HH:MM) example HourMil = 710 -> must be 07:10 HourMil = 1305 -> must be 13:05 Actually i am using this code (and works ok) for convert the column HourMil to the string representation. SELECT SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),1,2)+':'+SUBSTRING(LEFT('0',4-LEN(CAST(HourMil AS VARCHAR)))+CAST(HourMil AS VARCHAR),3,2) FROM MYTABLE but I think this code can be improved.

  • JQuery selector value escaping

    - by user53794
    I have a dropdown list that contains a series of options: <select id=SomeDropdown> <option value="a'b]&lt;p>">a'b]&lt;p></option> <option value="easy">easy</option> <select> Notice that the option value/text contains some nasty stuff: single quotes closing square bracket escaped html I need to remove the a'b]<p option but I'm having no luck writing the selector. Neither: $("#SomeDropdown >option[value='a''b]&lt;p>']"); or $("#SomeDropdown >option[value='a\'b]&lt;p>']"); are returning the option. What is the correct way to escape values when using the "value=" selector?

  • How to use intent between tabs in java/Android?

    - by Praveen Chandrasekaran
    I would need to know how to handle the intent between tabs. For example, I have a tab activity with two tabs. First on content is a text view. another one is a map view. When i click that text view it redirects to the tab2. it can be easily achieved by setCurrentTab(1) or setCurrentTabByTag("tab2") methods. But i want to pass lat and long values to that Map Activity to drop pin. What is the better way to use intents or getter/setter in java? What do you prefer? if your answer is "Intents". How?

  • Can't read output of httpservice

    - by tag
    I have an HTTPservice that uses id="myhttp" url="site.com/script.php" method="POST" resultFormat="xml" script.php returns $output = '' . $worked . ''; echo $output; Problem is when I try to read worked, it tells me the variable worked is not there event.result.worked myhttp.lastResult.worked The only thing that works is using toString() myhttp.lastResult.toString() or event.result.toString() What am I doing wrong? I plan to add other variables to the output time, so need to access each time and worked separately. I may also need to return multiple responses each with their own worked and time values. How do I do that. I was thinking to not use XML. Is there a more lightweight option. Flex shows I have the following options: array e4x flashvars object text xml

  • convert std object class to comma seperated string

    I have an std class object from twitter and i would like to take the ids array values and put them in a php variable $ids where $ids = (15761916,30144785,382747195,19399719).

  • Exponential volume control with a specified midpoint

    - by Lars
    I have a slider that returns values from 0 to 100. I am using this to control the gain of an oscillator. When the slider is at 0, I would like the gain to be 0.0 When the slider is at 50, I would like the gain to be 0.1 When the slider is at 100, I would like the gain to be 0.5 So I need to find an equation to get a smooth curve which passes through all of these points. I've got the following equation which gives an exponential curve and gets the start and end points correct, but I don't know how to force the curve through the middle point. Can anyone help? function logSlider(position){ var minP = 0; var maxP = 100; var minV = Math.log(0.0001); var maxV = Math.log(0.5); var scale = (maxV - minV) / (maxP - minP); return Math.exp(minV + scale*(position-minP)); }

  • There has to be an easier way.. pulling data from mysql

    - by Daniel Hunter
    I need to pull 3 values from a table and assign each one to a variable each value is based on to columns, a type and an id $ht_live_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='L'"); $ht_live_result = mysql_fetch_array($ht_live_query); $htCODE_Live = $ht_live_result['htcode']; You can see that I am assigning the desired value to the variable $htL $ht_General_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='G'"); $ht_General_result = mysql_fetch_array($ht_General_query); $htCODE_General = $ht_General_result['htcode']; $ht_Reward_query = mysql_query("SELECT htcode FROM coupon WHERE pid='$pid' AND type='R'"); $ht_Reward_result = mysql_fetch_array($ht_Reward_query); $htCODE_Reward = $ht_Reward_result ['htcode']; I know I am doing this the hard way but can not figure out how to do the foreach or while loop to attain the desired results.

  • mysql - check if data exists across multiple tables

    - by Dd Daym
    I am currently running this query inside MySQL to check if the specified values exists within the table associated with them. SELECT COUNT(artist.artist_id), COUNT(album.album_id), COUNT(tracks.track_id) FROM artist, album, tracks WHERE artist.artist_id = 320295 OR album.album_id = 1234 OR tracks.track_id = 809 The result I get from running this query is all 1, meaning that all the statements after the WHERE clause is true. To further check the query's reliability, I changed the tracks.track_ = 809 to 802, which I know does not match. However the results displayed are still all 1, meaning that they were all successfully matched even when I purposefully inserted a value which would not have matched. How do I get it to show 1 for a match and 0 for no matches within the same query? EDIT: I have inserted an image of the query running

  • How to Create an Array from a Single Variable and Form Multiple Foreach Loops?

    - by matphoto
    I'm fairly proficient in HTML/CSS, but very new when it comes to the likes of PHP and Javascript. I've jumped headfirst into coding Wordpress shortcodes (basically php functions), and so far, through trial and error and seemingly endless browser refreshes, I've been able to figure everything out. I just hit a huge wall though, hence why I'm here. Basically, I'm trying to give an attribute a list of values like: attr="23, 95, 136, ect" The function then needs to take that attribute variable and create an array with it: $arr = array($attr); To me that seems as if it would work, but the array takes the whole list as one value instead. After doing that I want to create a foreach loop that parses each number from the list, possibly through yet another foreach loop if possible, and returns a section of code for each one, and I'm not quite sure how to pull that off either. Any feedback would be greatly appreciated.

  • Why can I create a table with PRIMARY KEY on a nullable column?

    - by AlexKuznetsov
    The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

  • Performance considerations of a large hard-coded array in the .cs file

    - by terence
    I'm writing some code where performance is important. In one part of it, I have to compare a large set of pre-computed data against dynamic values. Currently, I'm storing that pre-computed data in a giant array in the .cs file: Data[] data = { /* my data set */ }; The data set is about 90kb, or roughly 13k elements. I was wondering if there's any downside to doing this, as opposed to loading it in from an external file? I'm not entirely sure how C# works internally, so I just wanted to be aware of any performance issues I might encounter with this method.

  • converting ID to column name and also replacing NULL with last known value.

  • Zend Database Adapter - Complex MySQL Query

    - by Sonny
    I have defined a function in my Navigation model that executes a query, and I was wondering if there's a more "Zendy" way of generating/executing the query. The query I'm using was proposed by Bill Karwin on another thread here for setting arbitrary record order. I tried using a prepared statement, but the values in the SIGN() function got quoted. I'm using the PDO adapter for MySQL. /** * */ public function setPosition($parentId, $oldPosition, $newPosition) { $parentId = intval($parentId); $oldPosition = intval($oldPosition); $newPosition = intval($newPosition); $this->getAdapter()->query(" UPDATE `navigation` SET `position` = CASE `position` WHEN $oldPosition THEN $newPosition ELSE `position` + SIGN($oldPosition - $newPosition) END WHERE `parent_id` = $parentId AND `position` BETWEEN LEAST($oldPosition, $newPosition) AND GREATEST($oldPosition, $newPosition) "); return $this; }

  • Query multiple currencies

    - by TiuTalk
    I need store multiple currencies on my database... Here's the problem: Example Tables: [ Products ] id (INT, PK) name (VARCHAR) price (DECIMAL) currency (INT, FK) [ Currencies ] id (INT, PK) name (VARCHAR) conversion (DECIMAL) # To U$ I'll store the product price with the currency selected by the user... Later I need to search the products using a price interval like "Search products with price from U$ 50 to U$ 100" and I need the system convert these values "on the fly" to run the SQL Query and filter the products. And I really don't know how to make this query... :/

  • Query filter design for string field

    - by Midhat
    A field in my table can have arbitrary strings. On the UI, there is a drop down having options like All, Value1, Value2 And the results were filtered by the selected option value. So far this is easy and adding new filters to the UI is not a problem. Needs no changes in my stored procedure. Now I want to have an "Others" option here as well, which will return rows not having the column value as Value1 or Value2. Apparently this will require a "not in" operator in my query, and will make maintenance difficult, as the list of values is likely to change Any suggestions, design tips?

  • What Can A 'TreeDict' (Or Treemap) Be Used For In Practice?

    - by Seun Osewa
    I'm developing a 'TreeDict' class in Python. This is a basically a dict that allows you to retrieve its key-value pairs in sorted order, just like the Treemap collection class in Java. I've implemented some functionality based on the way unique indexes in relational databases can be used, e.g. functions to let you retrieve values corresponding to a range of keys, keys greater than, less than or equal to a particular value in sorted order, strings or tuples that have a specific prefix in sorted order, etc. Unfortunately, I can't think of any real life problem that will require a class like this. I suspect that the reason we don't have sorted dicts in Python is that in practice they aren't required often enough to be worth it, but I want to be proved wrong. Can you think of any specific applications of a 'TreeDict'? Any real life problem that would be best solved by this data structure? I just want to know for sure whether this is worth it.

  • Reduce the number of queries in EF

    - by Gio2k
    I have the following Model: Entities: Product (Contains basic data for products: price, etc) Attribute (Contains data for all possible optional attributes) ProductAttribute (Contains data for optional attributes of a product, eg. Color, Model, Size). ProductAttribute is essentially a many to many relationship with payload (ProductId, AttributeID, Value) And this piece of code: private static void ListAttributes(Product p) { p.ProductAttributes.Load(); foreach (var att in p.ProductAttributes) { att.Attribute.load(); Console.WriteLine("\tAttribute Name:{0} - Value {1}", att.Attribute.Name, att.AttributeValue); } } This piece of code will fire a query for each time the att.Attribute.Load() method is called in the foreach loop, only so i can get display the name of the attribute. I would like to fetch the Attribute.Name together with the query that fetches all attribute values, i.e. join ProductAttribute and Attribute. Is there any way to achieve this within my method?

  • How to configure .NET test assembly to use website web.config?

    - by Morten Christiansen
    I've run into a problem setting up Selenium tests for an ASP.NET MVC project in cases where I need the settings provided in the web.config of the site under test. The problem is that I want to create a dummy user before running the test and this causes an error saying that the password-answer supplied is invalid. This is due to the test assembly not using the web.config, instead using default values for membership configuration. I've tried to copy the relevant section (membership configuration) into the app.config of the assembly without luck, but I admit I'm just grasping at straws here.

  • PHP 2d array question

    - by Neral
    Hello, So i have a 2 dimensional array that is used over several pages (session) $_SESSION ["Table"][$_SESSION ["count"]] [0] = $filename; $_SESSION ["Table"][$_SESSION ["count"]] [1] = $size; $_SESSION ["Table"][$_SESSION ["count"]] [2] = $floor; $_SESSION ["Table"][$_SESSION ["count"]] [3] = $phone; $_SESSION ["Table"][$_SESSION ["count"]] [4] = $network; $_SESSION ["Table"][$_SESSION ["count"]] [5] = $totalprice; This is used with a form so i can give in multiple input wich gets stored. But my question is how exactly can i calculate the AVERAGE of $total price of all given in results? Meaning for example i have 5 rows so this would mean 5 total prices. How exactly can i acces this value and count everything up / 5? This will happen in a other page so i would like to use sessions for this. /5 simply by count($_Session["table"]) , but really not sure about the other values. Kind Regards.

  • class method as hash value

    I have this working code: class Server def handle(&block) @block = block end def do @block.call end end class Client def initialize @server = Server.new @server.handle { action } end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server My Server will handle more then one action so I want to change code such way: class Server def handle(options) @block = options[:on_filter] end def do @block.call end end class Client def initialize @server = Server.new my_hash = { :on_filter => action } @server.handle(my_hash) end def action puts "some" end def call_server @server.do end end client = Client.new client.call_server It is incorrect code because action() method calls on create my_hash, but if I try to modify code to: my_hash = { :on_filter => { action } } i get error message. Is it possible to create hash with methods as hash values ?

  • PHP/Codeigniter processing a list with javascript

    - by user270797
    I have a list of items that the user can select. I want it to be more user friendly than standard checkboxes so I have seperate div's each with a unique id. When user clicks an item, I use javascript to display a tick on top of that item and change the style to show that it is highlighted. Im trying to work out how I can pass the list of id's when the form is submitted. Remember, if the user unticks an item, it should be removed from the list, I was thinking of using comma seperated values in a hidden text field but couldnt work out how to remove items from the start of the list if they were deselected
