• Is there a plugin to validate jQuery code ?

  - by aurelien

  I mean : is there a jQuery plugin which can check our code before launch it ? Example: I write this : jQuery('.myclass')css('color','red'); The plugin will show me some message like 'parse error line ...' because I forgot a dot Or : function test() { alert('test'); ... tet(); Message: The tet() function doesn't exist. So... What you do think ?

  Hello coders, I'm working on a php iban validator but i have a problem I wrote like this: function IbanValidator($value) { $iban = false; $value= strtoupper(trim($value)); # Change US text into your country code if(preg_match('/^US\d{7}0[A-Z0-9]{16}$/', $value)) { $number= substr($value,4,22).'2927'.substr($value,2,2); $number= str_replace( array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'), array(10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35), $number ); $iban = (1 == bcmod($number,97)) ? true; } return $iban; } Thanks.

• Google SpreadSheets - When using a time trigger in code, some cells getting '#N/A' value

  - by Robi

  I've created a Google spreadsheet with imported data on one cell, extracting specific string to another cell and pasting the data in a table with a trigger for every 2 hours. Now everything works perfectly when running the script manually but when logged out and waiting for the cells to fill, sometimes the pasted cell getting "#N/A" value. Here is the code I'm using: function PasteV(){ var ss = SpreadsheetApp.getActiveSpreadsheet(); var sheet = ss.getSheets()[0]; var timestamp= sheet.getRange("D1").getValue(); var sale= sheet.getRange("G1").getValue(); var rent= sheet.getRange("J1").getValue(); sheet.appendRow([timestamp, rent, sale]); } Again when running manually countless times - no problem. I'll appreciate your help. Thanks.

• A code using SharePoint classes doesn't run on systems not having SharePoint installed

  - by Manish

  I have a window application which uses SP classes to create a site. I works fine on a system having Windows Server 2003 R2 with sharepoint installed. But it doesn't work on a system having XP installed and SharePoint not installed. The fact is that both of these systems are on a intranet. So I assumed that the NON-SP system would be able to run the code and create a site on the system having SP installed if all the required parameters (like serverLocation, domain, username, password) are provided. I did copied the DLLs to these NON-SP system and referenced them to build the project: Microsoft.SharePoint.dll microsoft.sharepoint.portal.dll Microsoft.SharePoint.Publishing.dll But this too didn't worked. What am I missing? Is my assumption wrong?

• Find user defined functions and their usage in a massive code base

  - by Frenck

  Hi, I'm currently working with an massive PHP codebase, witch is completely undocumented. Here's the deal. All of the PHP code is included every page call. They build a simple include all kinda function that scan's the directory and includes all PHP files it can find. It works recursively for all the subfolders. I would like to know what functions are used in what files and from which files those functions came. I need to know this in order to switch to normale includes. Also it gives me more information about not used functions and files (since it a really old and big codebase, there is a lot of legacy in it). It there a tool or something for PHP that can check this kind of stuff in a codebase?

• Code coordinates to match compass bearings

  - by pinnacler

  Right now in Matlab (0,0) is the origin, 0 degrees / 2pi would be to the right of the cartesian plane and angles are measured counter clockwise with 90 degrees being at the top. I'm trying to write a simulator where the coordinates would match a compass bearing. 0/360 degrees or 2pi would be at the top and 90 degrees would be on the right. Any idea how to code in Matlab or c++? I'd imaging it'd be a matrix flipped about the x axis and rotated 90 degrees but I'm at a total loss. Phil

• How to make this code compile?

  - by skydoor

  // File: foo.c static int var; void foo() { var++; } // end of file foo.c // File bar.c: static int var; void bar() { var++; } // end of file bar.c // file main.c static int var; void main() { foo(); bar(); printf("%d", var); } // end of file main.c Question: Will the above program compile ? If so what will be the result ? I tested the code and found it couldn't be compiled. I try to use extern in main.c to use the function foo() and bar() but it still couldn't be compiled.

Why? How to solve?

• How to get surrounding method in Java source file for a given line number

  - by roesslerj

  I have a line number of a Java source file and want to get the sourounding method for that line number programatically. I looked into ANTLR which didn't help me much. Janino (http://www.janino.net) seems promising, I would scan and parse (and if necessary compile) the code. Then I could use JDI and ReferenceType.locationsOfLine(int lineNumber) Still I don't know how to use JDI for doing this and didn't find a tutorial that goes anywhere in this direction. Maybe there is some other way that I am completely missing.

• Telling between a "natural" HTTP 404 and a PHP Generated one

  - by JCOC611

  So I have a file that should never be accessed by a user directly, but included in another PHP file. If the file is called directly, it generates a HTTP Status 404 Not Found to trick a possible attacker that such file doesn't exist. However, if the hacker could tell that the 404 was generated by PHP or is not "natural" then the whole point of the header would be lost. So is it possible to tell whether the 404 was generated by the server naturally (because the file really doesn't exist) or by a PHP code? PS: I know this question might seem pretty weird lol

• Unit testing UDP socket handling code

  - by JustJeff

  Are there any 'good' ways to cause a thread waiting on a recvfrom() call to become unblocked and return with an error? The motivation for this is to write unit tests for a system which includes a unit that reads UDP datagrams. One of the branches handles errors on the recvfrom call itself. The code isn't required to distinguish between different types of errors, it just has to set a flag. I've thought of closing the socket from another thread, or do a shutdown on it, to cause recvfrom to return with an error, but this seems a bit heavy handed. I've seen mention elsewhere that sending an over-sized packet would do it, and so set up an experiment where a 16K buffer was sent to a recvfrom waiting for just 4K, but that didn't result in an error. The recvfrom just return 4096, to indicate it had gotten that many bytes.

• Flash: dynamically adding events code to instances possible?

  - by Kohan

  I want to make a movieclip invisible initially but i dont want to set it manually within the properties in flash because i cant then see it on the scene. I was hoping i could add some code like so: MC Frame one. this.onClipEvent(load) { this._alpha = 0; } but I cannot. How can i set the MC _alpha to 0 for all instances without adding it manually to each instance or setting it in the properties? edit: or creating a class for it just to set the alpha.

• Visual Studio: What approach do you use to 'template' plumbing for similiar projects?

  - by Sosh

  When building ASP.NET projects there is a certain amount of boilerplate, or plumbing that needs to be done, which is often identical across projects. This is especially the case with MVC and ALT.NET approaches. [I'm thinking of things such as: IoC, ORM, Solution structure (projects), Session Management, User Management, I18n etc.] I would like to know what approach you find best for 'reusing' this plumbing accross projects? Have a 'master solution' which you duplicate and rename somehow? (I'm using a this to a degree at the moment, but it's fairly messy. Would be interested how people do this 'better') Mainly rely on Shared Library projects? (I find this appropriate for some things, but too restrictive for things that have to be customised) Code generation tools, such as T4? (Similar to the approach used by SharpArchitecture - have not tried this myself) Something else? Thanks for sharing your experiences!

• An efficient code to determine if a set is a subset of another set

  - by Edward

  I am looking for an efficient way to determine if a set is a subset of another set in Matlab or Mathematica. Example: Set A = [1 2 3 4] Set B = [4 3] Set C = [3 4 1] Set D = [4 3 2 1] The output should be: Set A Sets B and C belong to set A because A contains all of their elements, therefore, they can be deleted (the order of elements in a set doesn't matter). Set D has the same elements as set A and since set A precedes set D, I would like to simply keep set A and delete set D. So there are two essential rules: 1. Delete a set if it is a subset of another set 2. Delete a set if its elements are the same as those of a preceding set My Matlab code is not very efficient at doing this - it mostly consists of nested loops. Suggestions are very welcome! Additional explanation: the issue is that with a large number of sets there will be a very large number of pairwise comparisons.

• Perform Grouping of Resultset in Code

  - by NinjaBomb

  Stackoverflowers, I have a resultset from a SQL query in the form of: Category Column2 Column3 A 2 3.50 A 3 2 B 3 2 B 1 5 ... I need to group the resultset based on the Category column and sum the values for Column2 and Column3. I have to do it in code because I cannot perform the grouping in the SQL query that gets the data due to the complexity of the query (long story). This grouped data will then be displayed in a table. I have it working for specific set of values in the Category column, but I would like a solution that would handle any possible values that appear in the Category column. I know there has to be a straightforward, efficient way to do it but I cannot wrap my head around it right now. How would you accomplish it?

• What is "src" directory created by Eclipse?

  - by Roman

  I just installed Eclipse. The Eclipse created the "workspace" folder. In this folder I created a "game" sub-folder (for my class called "game"). I have already .java files for that project (I wrote them in a text editor before I started to use Eclipse). I put all my .java file into the "game" directory. In Eclipse I created a "New Java Project" from existing code. What wanders me is that the Eclipse create a "src" sub-folder into my "game" folder. As far as I understand "src" stands for "source". But my source (.java files) is in the "game" (by the construction). Am I doing something wrong?

• Cleaning up code - flatten a nested hash structure

  - by knorv

  The following Perl sub flattens a nested hash structure: sub flatten { my $hashref = shift; my %hash; my %i = %{$hashref}; foreach my $ii (keys(%i)) { my %j = %{$i{$ii}}; foreach my $jj (keys(%j)) { my %k = %{$j{$jj}}; foreach my $kk (keys(%k)) { my $value = $k{$kk}; $hash{$kk} = $value; } } } return %hash; } While the code works it is not very readable or clean. My question is two-fold: In what ways does it not correspond to modern Perl best practices? How would you clean it up?

• Generate markdown from source code doc-comments

  - by erikkallen

  Is there any easy way to generate markdown from source code comments? I'm looking for something similar to Sandcastle, but with Markdown (or something like it) as output. The full story is that I use DokuWiki to generate documentation. It has many nice properties, including that all its data is stored in text files. So my idea is that I should somehow be able to get my API docs into the same place as the rest of my documentation. So far my best bet seems to be to write a custom documenter for NDoc3, but perhaps someone has already done something similar which would save me the trouble. I realize I might need to tweak it a little due to slight syntax differences.
