  • Unable to access global variable defined in settings.php [Drupal]

    - by Senthil
    I am developing a website using Drupal 6.16. I want to define a variable in settings.php like $ge_path = 'some/path/here'; And I want to use it inside my modules. function mymodule_block(....) { global $ge_path; $fullPath = $ge_path . '/another/path'; doSomething($fullPath); } But I am getting NULL as the value of $ge_path. Why am I not able to access the global variable defines in settings.php? How can I get the proper value inside my module functions? The funny thing is, I am able to access $db_url['default'] and $db_url['mydatabase'] etc.. which are defined just two lines above $ge_path in settings.php!

  • Multiple Controls on a Page with Multiple Instances of Javascript

    - by mattdell
    I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

  • Unix tree convert to recursive php array

    - by Fordnox
    I have a response from remote server like this: /home/computer/Downloads |-- /home/computer/Downloads/Apple | `-- /home/computer/Downloads/Apple/Pad |-- /home/computer/Downloads/Empty_Folder `-- /home/computer/Downloads/Subfolder |-- /home/computer/Downloads/Subfolder/Empty `-- /home/computer/Downloads/Subfolder/SubSubFolder `-- /home/computer/Downloads/Subfolder/SubSubFolder/Test this is the output for command computer@athome:$ tree -df --noreport -L 5 /home/computer/Downloads/ I would like to parse this string to recursive php array or object, something like this. I would show only part of result to get the idea. array( 'title' => '/home/computer/Downloads', 'children' => array( 0 => array( 'title' => '/home/computer/Downloads/Apple', 'children' => array( ... ) ) ); Response from server can change according to scanned directory. Can someone help me write this function. Please note that this is response from remote server and php functions can not scan any remote dir.

  • need identical string comparison function in php and java

    - by steelbytes
    I have sorted list of strings that I move between php and java. to be able to bsearch on this data, I need the same comparison function. any idea what string compare functions I can use that will always give the same result in both? eg php's strcmp() vs java's String.compareTo() yes I know I could make my own string compare that does char by char carefully, but I was hoping there's a simple answer. PS, don't care if case sensitive or not, as long as it is consistant.

  • OpenCV to use in memory buffers or file pointers

    - by The Unknown
    The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments. For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk. Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory. I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks! My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.

  • ruby c extensions: character values over 127

    - by Adrian
    I am trying to make a C extension for Ruby that includes a method returning a string, which will sometimes have character values that need to be in an unsigned char. In http://github.com/shyouhei/ruby/blob/trunk/README.EXT, all of the functions listed for turning C strings into Ruby strings take signed chars. So I couldn't do this: unsigned char bytes[] = {0xf0, 0xf1, 0xf2}; return rb_str_new(bytes, 3); How could I make a method that returns these types of strings? In other words, how would I make a C extension with a method returning "\xff"?

  • Private JQuery instance

    - by Nir Levy
    We are writing a SaaS like solution that requires our customers to SCRIPT SRC some javascript code we are building (think Google Analytics scenario). We would like to use JQuery. However, since our customers might already have conflicting JQuery versions or other conflicting frameworks (prototype.js for one) we cannot tell them to source jquery.js. We were thinking of coping the jquery source as to create a 'private' jquery instance and simple search/replace the JQuery and $ functions with myJQuery and $J Is there any reason for this not to work? has anyone tried something like this? What can we do about plugins?

  • jQuery slide up/down on hover bug

    - by Eirik Lillebo
    Hi! I have one large div with one smaller div inside it. The smaller div is at first displayed as hidden. When the user hovers the mouse over the large container-div the smaller div is animated in with the show/hide-functions. So far everything works fine. However. The smaller div is animated in from the bottom - so if I let the cursor hover over the container at the very bottom, it's hovering over the animation of the smaller div while it's sliding in. So now the cursor is hovering over the smaller div instead of the larger div, and thus triggering the hide-function on the smaller div. This creates an infinite loop of show/hide calls as the smaller div slides in and out of where the cursor is pointing. Any ideas how to avoid this and not break the hovering on the container as the smaller div enters?

  • Declare two classes from eachother.

    - by tumba25
    I'm writing a app in NetBeans. I have two classes MyApp_View and MyApp_Functions. The MyApp_View class starts like this public class MyApp_View extends FrameView { MyApp_Functions My_functions = new MyApp_Functions(); public MyApp_View(SingleFrameApplication app) { super(app); In MyApp_Functions I have MyApp_View my_view = new MyApp_View(null); I want to access the public variables in MyApp_View from MyApp_Functions and the public methods in functions from view, but have no success with this. Is this doable? And how?

  • Error in R for missing object

    - by griffin
    I have several nested functions, some of which as called in lapply clauses. In the process, sometimes I don't set a default for a parameter and instead check if it was supplied using the missing function. I'm getting a strange error right now when I'm not passing a value for a parameter, it has no default, yet missing resolves to FALSE. And when I try to use or check the parameter in any other way (using length, exists, etc.), I get an error: Error in try(length(x)) : argument "data" is missing, with no default Has anyone experienced this failure of the missing function before?

  • How to get fopen to timeout properly

    - by beagleguy
    hey all, I have the following snippet of php code if($fp = fopen($url, 'r')) { stream_set_timeout($fp, 1); stream_set_blocking($fp, 0); } $info = stream_get_meta_data($fp); I'd like the request to timeout after 1 second... if I put a sleep(20) in my $url that I'm reading it just waits the whole 20 seconds and never times out. Is there a better way to do timeouts with fopen? If I use ini_set('default_socket_timeout',2); above that code it times out properly but $info then becomes null so ideally I'd like to use the stream functions. thanks

  • JQuery Scrollable List Dissapears if scrolled IE7

    - by namtax
    Hi there I have created a time picker using jquery, using the following code // Display Time Picker $('.time').click(function(){ $('.timePicker').remove(); var thisTime = $(this); var timePicker = '<ul class="timePicker">' timePicker += '<li>09:00</li>' timePicker += '<li>09:15</li>' timePicker += '</ul>' thisTime.after(timePicker); $('.timePicker').fadeIn() $('.timePicker li').click(function(){ term = $(this).html(); $(thisTime).val(term); $('.timePicker').remove(); }); }).blur(function(){ $('.timePicker').fadeOut(); }); This adds a dropdown scrollable list of times to any input field with the class "time". This functions as expected in all browsers apart from IE7, where if I scroll the list to choose a time lower down in the list, the list dissapears.. Hope that makes sense, any help would be much appreciated Many thanks

  • Why must "stride" in the System.Drawing.Bitmap constructor be a multiple of 4?

    - by Gorchestopher H
    I am writing an application that requires me to take a proprietary bitmap format (an MVTec Halcon HImage) and convert it into a System.Drawing.Bitmap in C#. The only proprietary functions given to me to help me do this involve me writing to file, except for the use of a "get pointer" function. This function is great, it gives me a pointer to the pixel data, the width, the height, and the type of the image. My issue is that when I create my System.Drawing.Bitmap using the constructor: new System.Drawing.Bitmap(width, height, stride, format, scan) I need to specify a "stride" that is a multiple of 4. This may be a problem as I am unsure what size bitmap my function will be hit with. Supposing I end up with a bitmap that is 111x111 pixels, I have no way to run this function other than adding a bogus column to my image or subtracting 3 columns. Is there a way I can sneak around this limitation?

  • Using free function as pseudo-constructors to exploit template parameter deduction

    - by Poita_
    Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A a, B b) { return std::pair<A, B>(a, b); } // This allows you to call make_pair(1, 2), // instead of having to type pair<int, int>(1, 2) // as you can't get type deduction from the constructor. I find myself using this quite often, so I was just wondering if many other people use it, and if there is a name for this pattern?

  • Django's manage.py shell won't indent

    - by hora
    I seem to have run into a strange bug or more likely some setting I am unfamiliar with on my system that is not allowing me to tab when I am in Django's shell (python manage.py shell is how I run it). For obvious reasons this is proving to be annoying since I can't do any loops or conditonals in the shell. If I hit tab it completes all functions that are available to me, like bash does in a terminal. I've tried just using spaces for my indents but I always get an indentation error. Does anyone know why this is happening and what I can do to get tab to work in my shell again? (It may be relevant to know that this is on a Ubuntu 9.04 system). Edit: tab works fine in the regular pythong shell, it's only in django's that it doesn't. Thanks.

  • Generate multiple graphics from within an R function

    - by William Doane
    I'd like to spawn several graphics windows from within a function in R using ggplot graphics... testf <- function(a, b) { devAskNewPage(TRUE) qplot(a, b); # grid.newpage(recording = TRUE) dev.new() qplot(a, a+a); # grid.newpage(recording = TRUE) dev.new() qplot(b, b+b); } library(ggplot2) x <- rnorm(50) y <- rnorm(50) testf(x, y) However, neither dev.new() nor grid.newpage() seems to flush the preceding plot. I know that, in R, functions normally only produce the last thing they evaluate, but I'd like to understand the process better and to learn of any possible workarounds. Thoughts?

  • How to determine position (x,y) relative to the page of every character inside spans through javascript?

    - by Fernando
    This is as simple as I can get. I will have several spans randomly positioned on the screen through something like: $(".hidden:first").css('-webkit-transform','rotate('+((0.5-Math.random())*40)+'deg)'); $(".hidden:first").animate({ left: '+=' + (((screen.width-800-224)/2) + Math.random()*800), top: '+=' + (50+Math.random()*600) } [...] and later on I would like to iterate through every char of every of those elements (that are randomly position and have random rotation), and I would need to discover the (x,y) position of every character on the screen so I can colorize it, forming certain draws according to certain functions. Is this easily achievable? I am really inexperienced at javascript. Thanks. Fernando.

  • I need a program to store the database script for oracle

    - by Hakan Kara
    We are developing a project that has 3 enviroments (development, test, production) So there are 3 databases (actually more than 3, because we have 5 customers so we have more than 10 databases) and they must be synchronised. There are 30 coders working for this project. Everone adds, deletes, and changes procedures, table columns etc. We need a program to store our database scripts like visual studio's team foundation server. See the change history of script file. Everyone must access that program and be able to put their scripts. Recover previous versions of script file. Execute these scripts over a selected database. Compare databases by procedures (not only by name, by content of procedure), functions, table columns, packages etc. I am searching a program like that. Which one do you suggest me?

  • Alternative to c++ static virtual methods

    - by Jaime Pardos
    In C++ is not possible to declare a static virtual function, neither cast a non-static function to a C style function pointer. Now, I have a plain ol' C SDK that uses function pointers heavily. I have to fill a structure with several function pointers. I was planning to use an abstract class with a bunch of static pure virtual methods, and redefine them in derived classes and fill the structure with them. It wasn't until then that I realized that static virtual are not allowed in C++. Is there any good alternative? The best I can think of is defining some pure virtual methods GetFuncA(), GetFuncB(),... and some static members FuncA()/FuncB() in each derived class, which would be returned by the GetFuncX(). Then a function in the abstract class would call those functions to get the pointers and fill the structure.

  • How do I combine an unmanaged dll and a managed assembly into one file?

    - by Lasse V. Karlsen
    SQLite from PHX Software has combined a managed assembly (System.Data.SQLite) with an unmanaged dll (the SQLite 32- or 64-bit dll) into one file, and managed to link them together. How do I do this? Do I need to embed the managed assembly into the unmanaged dll, or vice versa? ie. my questions are: In which order do I need to do this? What tools or knowledge do I need in order to do this? How (if different) do I link to the exported functions from the unmanaged dll in my managed code? The reason I ask this is that I want to build a managed zLib wrapper. I know there is managed classes in .NET but from experience they're a bit limited (and a bit boneheaded in that they don't do proper buffering), so I'd like to create my own copy, also because I want to learn how to do this. So does anyone know what I need to do and how?

  • Interpolating 1D Gaussian into 2D Gaussian

    - by Drazick
    Let's say I have a 1D Gaussian function. Its length is 600 for that matter. I want to Interpolate it into 2D Gaussian of the size 600 X 600. This is the code I wrote (OTFx is the Gaussian Function, OTF - 2d Interpolated Function): [x, y] = meshgrid([-300:299], [-300:299]); r = sqrt((x .^ 2) + (y .^ 2)); OTF = interp1([-300:299], OTFx, r(:), 'spline'); OTF = reshape(OTF, [600, 600]); The problem is I get Overshoot at the end: How can I prevent it? Is there better Interpolating algorithm for Monotonic Descending Functions?

  • In C, how do you capture a group with regex?

    - by Sylvain
    Hi, I'm trying to extract a string from another using regex. I'm using the POSIX regex functions (regcomp, regexec ...), and I fail at capturing a group ... For instance, let the pattern be something as simple as "MAIL FROM:<(.*)>" (with REG_EXTENDED cflags) I want to capture everything between '<' and '' My problem is that regmatch_t gives me the boundaries of the whole pattern (MAIL FROM:<...) instead of just what's between the parenthesis ... What am I missing ? Thanks in advance,

  • How can I fix the scroll bug when using Windows rich edit controls in wxpython?

    - by ChrisD
    When using wx.TextCtl with the wx.TE_RICH2 option in windows, I get this strange bug with the auto-scroll when using the AppendText function. It scrolls so that all the text is above the visible area, which isn't very useful behaviour. I tried just adding a call to ScrollLines(-1) after appending the text - which does scroll it to the correct position - but this can lead to the window flashing when it auto-scrolls. So I'm looking for another way to automatically scroll to the bottom. So far, my solution is to bypass the AppendText functions auto-scroll and implement my own, like this: def append_text(textctrl, text): before_number_of_lines = textctrl.GetNumberOfLines() textctrl.SetInsertionPointEnd() textctrl.WriteText(text) after_number_of_lines = textctrl.GetNumberOfLines() textctrl.ScrollLines(before_number_of_lines - after_number_of_lines + 1) Is there a better way?

  • Algorithm for Source Control System?

    - by Michael Stum
    I need to write a simple source control system and wonder what algorithm I would use for file differences? I don't want to look into existing source code due to license concerns. I need to have it licensed under MPL so I can't look at any of the existing systems like CVS or Mercurial as they are all GPL licensed. Just to give some background, I just need some really simple functions - binary files in a folder. no subfolders and every file behaves like it's own repository. No Metadata except for some permissions. Overall really simple stuff, my single concern really is how to store only the differences of a file from revision to revision without wasting too much space but also without being too inefficient (Maybe store a full version every X changes, a bit like Keyframes in Videos?)
