  • Regular Expression to get the size value of a CSS property?

    - by thiesdiggity
    I wrote a regular expression to get the size from a CSS property: /(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i but for some reason its not working as intended. For example, when I run the following: preg_match_all('/(([+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i', "border-bottom:1px solid #99999;", $matches); It outputs: 1px 99999; But I only want the 1px value returned. I understand why its returning the above but can't seem to figure out how to only return the size and not the color value. I tried using the following negative lookbehind but it's not working either: /(((?<!#\d{3}|#\d{6})[+-]?\d*\.?\d+(\s)*(px|em|ex|pt|in|pc|mm|cm)?)|thin|medium|thick)(\s|;|$)/i I want to use preg_match_all for those CSS properties that can have multiple size values (i.e. margin). Anyone have any ideas how to get this regex to return only the size values? Thanks for your help!

  • Cleaner way to store to replace a scalar hash value with an array ref?

    - by user275455
    I am building a hash where the keys, associated with scalars, are not necessarily unique. I want the desired behavior to be that if the key is unique, the value is the scalar. If the key is not unique, I want the value to be an array reference of the scalars associated witht the key. Since the hash is built up iteratively, I don't know if the key is unique ahead of time. Right now, I am doing something like this: if(!defined($hash{$key})){ $hash{$key} = $val; } elseif(ref($hash{$key}) ne 'ARRAY'){ my @a; push(@a, $hash{$key}); push(@, $val); $hash{$key} = \@a; } else{ push(@{$hash{$key}}, $val); } Is there a simpler way to do this?

  • How to merge arrays with same key and different value in PHP?

    - by Martin
    Hi guys, I have arrays similarly to these: 0 => Array ( [0] => Finance / Shopping / Food, [1] => 47 ) 1 => Array ( [0] => Finance / Shopping / Food, [1] => 25 ) 2 => Array ( [0] => Finance / Shopping / Electronic, [1] => 190 ) I need to create one array with [0] as a key and [1] as value. The tricky part is that if the [0] is same it add [1] to existing value. So the result I want is: array ([Finance / Shopping / Food]=> 72, [Finance / Shopping / Electronic] => 190); thanks

  • What is the proper way to check the previous value of a field before saving an object? (Using Django

    - by anonymous coward
    I have a Django Model with updated_by and an approved_by fields, both are ForeignKey fields to the built-in (auth) User models. I am aware that with updated_by, it's easy enough to simply over-ride the .save() method on the Model, and shove the request.user in that field before saving. However, for approved_by, this field should only ever be filled in when a related field (date_approved) is first filled in. I'm somewhat certain that I can check this logically, and fill in the field if the previous value was empty. What is the proper way to check the previous value of a field before saving an object? I do not anticipate that date_approved will ever be changed or updated, nor should there be any reason to ever update the approved_by entry. UPDATE: Regarding forms/validation, I should have mentioned that none of the fields in question are seen by or editable by users of the site. If I have misunderstood, I'm sorry, but I'm not sure how forms and validation apply to my question.

  • How do I return the numeric value from a database query in PHP?

    - by Luke
    Hello, I am looking to retreive a numerical value from the database function adminLevel() { $q = "SELECT userlevel FROM ".TBL_USERS." WHERE id = '$_SESSION[id]'"; return mysql_query($q, $this->connection); } This is the SQL. I then wrote the following php/html: <?php $q = $database->adminLevel(); if ($q > 7) { ?> <a href="newleague.php">Create a new league</a> <? } ?> The problem I have is that the userlevel returned isn't affecting the if statement. It is always displayed. How do i get it to test the value of userlevel is greater than 7? Thanks

  • Is there a way to set the value of $? in a mock in Ruby?

    - by rleber
    I am testing some scripts that interface with system commands. Their logic depends on the return code of the system commands, i.e. the value of $?. So, as a simplified example, the script might say: def foo(command) output=`#{command}` if $?==0 'succeeded' else 'failed' end end In order to be able to test these methods properly, I would like to be able to stub out the Kernel backquote call, and set $? to an arbitrary value, to see if I get appropriate behavior from the logic in the method after the backquote call. I can't figure out a way to do this. (In case it matters, I'm testing using Test::Unit and Mocha.)

  • IE7 Negative value cuts off half the element - bug?

    - by Yammi
    I've relatively positioned one of the elements with negative 'top' and 'left' values, the negative 'left' value actually takes the element outside of the 'body' width, this seems fine in all browsers apart from IE7 where it just cuts it off. establi.sh I thought it might be that weird bug where if it's outside the parent container then you have to set a z-index but that didn't work, then I thought it might be the hasLayout bug but trying to fix that didn't work. I'm not an expert on IE browsers so need some help. I'm thinking IE7 might be choking as the negative left value actually takes it outside the body? Thanks

  • How to change the value of progressbar in C#?

    - by shekhar
    Hi, I want to add an progress bar into my C# based application. I would like to know what is the good way of updating its value at particular events? My problem is, I have single function in UI which does all the processing.This function in turn calls many more functions, creates objects, updates database, etc. (basically performs all the work) and returns values in an output file. I have access to that function only. So in this how to update the progressbar's value at the end of each step? What is the best practice for this kind of situation? What is the good way to keep UI logic and business logic seperate? I want to avoid writting progressbar related code in my library code. Please suggest some solution. Thanks and Regards,

  • Does a CPU assigns a value atomically to memory?

    - by Poni
    Hi! A quick question I've been wondering about for some time; Does the CPU assign values atomically, or, is it bit by bit (say for example a 32bit integer). If it's bit by bit, could another thread accessing this exact location get a "part" of the to-be-assigned value? Think of this: I have two threads and one shared "unsigned int" variable (call it "g_uiVal"). Both threads loop. On is printing "g_uiVal" with printf("%u\n", g_uiVal). The second just increase this number. Will the printing thread ever print something that is totally not or part of "g_uiVal"'s value? In code: unsigned int g_uiVal; void thread_writer() { g_uiVal++; } void thread_reader() { while(1) printf("%u\n", g_uiVal); }

  • Is it possible to inspect the contents of a Table Value Parameter via the debugger?

    - by Stephen Edmonds
    Does anyone know if it is possible to use the Visual Studio / SQL Server Management Studio debugger to inspect the contents of a Table Value Parameter passed to a stored procedure? To give a trivial example: CREATE TYPE [dbo].[ControllerId] AS TABLE( [id] [nvarchar](max) NOT NULL ) GO CREATE PROCEDURE [dbo].[test] @controllerData [dbo].[ControllerId] READONLY AS BEGIN SELECT COUNT(*) FROM @controllerData; END DECLARE @SampleData as [dbo].[ControllerId]; INSERT INTO @SampleData ([id]) VALUES ('test'), ('test2'); exec [dbo].[test] @SampleData; Using the above with a break point on the exec statement, I am able to step into the stored procedure without any trouble. The debugger shows that the @controllerData local has a value of '(table)' but I have not found any tool that would allow me to actual view the rows that make up that table.

  • c# converting select case VBA to c# SWITCH

  • Get URL parameter function that gets value of url part or returns true if it's there but with no val

    - by LLer
    I'm using the following function to get a URL parameter. function gup(name, url) { name = name.replace(/[\[]/, '\\\[').replace(/[\]]/, '\\\]'); var results = new RegExp('[\\?&]'+name+'=?([^&#]*)').exec(url || window.location.href); return results == null ? null : results[1]; } It works only if the parameter has a value, for example. gup('a', 'http://example.com/page.php?a=1&b=2'); will return 1. But if I try gup('a', 'http://example.com/page.php?a&b=2'); It returns null. I want it to return true because parameter "a" exists in that url, even though it has no value it's still there and gup() should return true. Could I get a bit of help rewriting this? I'm not that good with regex.

  • Will Sytem.currentTimeMillis always return a value >= previous calls?

    - by 1984isnotamanual
    http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#currentTimeMillis() says: Returns the current time in milliseconds. Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds. It is not clear to me if I am guaranteed that this code will always print ever increasing (or the same) numbers. while (1) { System.out.println(System.currentTimeMillis() ); }

  • Is it a good design to return value by parameter?

    - by aztack
    bool is_something_ok(int param,SomeStruct* p) { bool is_ok = false; // check if is_ok if(is_ok) // set p to some valid value else // set p to NULL return is_ok; } this function return true and set p to a valid value if "something is ok" otherwise return false and set p to NULL Is that a good or bad design? personally, i feel uncomfortable when i use it. If there is no document and comment, i really don know how to use it. BTW:Is there some authoritative book/article about API design?

What is the difference? what is the mechanism behind of val function in jQuery? quote: $(document).ready(function() { $('#user_name').focus( function(){$(this).val('');} ); }); //error code: not working... $(document).ready(function() { $('#user_name').focus( function(){$(this)value='';} ); });
