• AIX 6.1 unable to build apache module

  - by user3715581

  In Aix 6.1/ Apache version 2.2.8 packaged as part of IBM WebSphere. We should have had mod_dumpio for this version but for some reasons IBM did not include it. So we are trying to build this module(in few many ways) but none of them worked. 1) Using apxs:- Failed with the "xlc_r" not found as compile option for libtool. So based on an article online, we changed to "gcc" and we have to remove -qmaxmem and -qHALT to make it work. Result we see a .lo created but LoadModule fails(unable to find .loader section). 2) Using gcc:- Command "gcc -fpic -DSHARED_MODULE -I -c mod_dumpio.c" After running this command, we can see .o file created and then we tried to execute "ld -Bshareable -o mod_dumpio.so mod_dumpio.o" whereas AIX complaining about -Bshareable so we tried using this command "gcc -shared -I -o mod_dumpio.so mod_dumpio.o" whereas the error was "libgcc_s" not found. Then we added -static-libgcc to the above command and it was not resolving .h file functions (Unknown symbols). From IBM AIX site, libgcc_s costs around $2k. We think our second approach may work but we dont know how to instruct gcc to look for .h files while building .so from .o. Any help is appreciated.

• TabBar Support of Three20 iPhone Photo Gallery

  - by dooonot

  Hi all, I wend through this tutorial and created a photo gallery for the iPhone. Now I want to add it to my TabBar project. I already heard, that Three20 doesn't support XIB, so I changed my whole tab bar setup to programmatically. I think I am not too far from a final solution. I was able to get the photo gallery working in one tab but without functions (click on a pic -- it opens, etc). There is no navigation on top of the page that leads you to the detail image page. I faced this when I removed this from didFinishLaunchingWithOptions-method in app delegate: // Override point for customization after application launch TTNavigator* navigator = [TTNavigator navigator]; TTURLMap* map = navigator.URLMap; [map from:@"demo://album" toViewController: [AlbumController class]]; [navigator openURLAction:[TTURLAction actionWithURLPath:@"demo://album"]]; return YES; I had to remove it because otherwise the whole tab bar is not shown. The photo gallery uses the whole screen. I am not sure if it is just not shown, or not loaded. I also tried: tabbar.hidesBottomBarWhenPushed = NO; But that did not work at all. I tried to add the TTNavigator-code to loadView(), viewDidLoad() and init() in the AlbumController itself without a result. Does anyone know where I have to put this in order to get it working? Thanks guys, Cheers, dooonot

• How to animate button text? (loading type of animation) - jquery?

  - by AL

  I got something that I want to do and want to see what you guys think and how can it be implemented. I got a form in a page and the form will submit to itself to perform some process (run functions) in a class. Upon clicking the submit button, I want to animate the button text to “SUBMIT .” -> “SUBMIT ..” -> “SUBMIT …” -> “SUBMIT ….” -> “SUBMIT ….” and then back again. Sort of “animate” the button text. Once the whole process is done, the button text will goes back to be “SUBMIT” text again. Please note that I am not looking for image button solution, meaning that I do not want to implement gif animated button image. Anyone done this before or know how this can be done? I have google but seems nothing of this kind to be found. Thanks! AL

• MySQL Datefields: duplicate or calculate?

  - by Konerak

  We are using a table with a structure imposed upon us more than 10 years ago. We are allowed to add columns, but urged not to change existing columns. Certain columns are meant to represent dates, but are put in different format. Amongst others: * CHAR(6): YYMMDD * CHAR(6): DDMMYY * CHAR(8): YYYYMMDD * CHAR(8): DDMMYYYY * DATE * DATETIME Since we now would like to do some more complex queries, using advanced date functions, my manager proposed to d*uplicate those problem columns* to a proper FORMATTED_OLDCOLUMNNAME column using a DATE or DATETIME format. Is this the way to go? Couldn't we just use the STR_TO_DATE function each time we accessed the columns? To avoid every query having to copy-paste the function, I could still work with a view or a stored procedure, but duplicating data to avoid recalculation sounds wrong. Solutions I see (I guess I prefer 2.2.1) 1. Physically duplicate columns 1.1 In the same table 1.1.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.1.2 Maintained by a trigger on each modification 1.2 In a separate table 1.2.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.2.2 Maintained by a trigger on each modification 2. On-demand transformation 2.1 Each query has to perform the transformation 2.1.1 Using copy-paste in the source code 2.1.2 Using a library 2.1.3 Using a STORED PROCEDURE 2.2 A view performs the transformation 2.2.1 A separate table replacing the entire table 2.2.2 A separate table just adding the date-fields for the primary keys Am I right to say it's better to recalculate than to store? And would a view be a good solution?

• LINQ to SQL: NOTing a prebuilt expression

  - by ck

  I'm building a library of functions for one of my core L2S classes, all of which return a bool to allow checking for certain situations. Example: Expression<Func<Account, bool>> IsSomethingX = a => a.AccountSupplementary != null && a.AccountSupplementary.SomethingXFlag != null && a.AccountSupplementary.SomethingXFlag.Value; Now to query where this is not true, I CAN'T do this: var myAccounts= context.Accounts .Where(!IsSomethingX); // does not compile However, using the syntax from the PredicateBuilder class, I've come up with this: public static IQueryable<T> WhereNot<T>(this IQueryable<T> items, Expression<Func<T, bool>> expr1) { var invokedExpr = Expression.Invoke(expr1, expr1.Parameters.Cast<Expression>()); return items.Where(Expression.Lambda<Func<T, bool>> (Expression.Not(invokedExpr), expr1.Parameters)); } var myAccounts= context.Accounts .WhereNot(IsSomethingX); // does compile which actually produces the correct SQL. Does this look like a good solution, and is there anything I need to be aware of that might cause me problems in future?

• Is there a way to receive data as unsigned char over UDP on Qt?

  - by user269037

  I need to send floating point numbers using a UDP connection to a Qt application. Now in Qt the only function available is qint64 readDatagram ( char * data, qint64 maxSize, QHostAddress * address = 0, quint16 * port = 0 ) which accepts data in the form of signed character buffer. I can convert my float into a string and send it but it will obviously not be very efficient converting a 4 byte float into a much longer sized character buffer. I got hold of these 2 functions to convert a 4 byte float into an unsinged 32 bit integer to transfer over network which works fine for a simple C++ UDP program but for Qt I need to receive the data as unsigned char. Is it possible to avoid converting the floatinf point data into a string and then sending it? uint32_t htonf(float f) { uint32_t p; uint32_t sign; if (f < 0) { sign = 1; f = -f; } else { sign = 0; } p = ((((uint32_t)f)&0x7fff)<<16) | (sign<<31); // Whole part and sign. p |= (uint32_t)(((f - (int)f) * 65536.0f))&0xffff; // Fraction. return p; } float ntohf(uint32_t p) { float f = ((p>>16)&0x7fff); // Whole part. f += (p&0xffff) / 65536.0f; // Fraction. if (((p>>31)&0x1) == 0x1) { f = -f; } // Sign bit set. return f; }

• C# Timer -- measuring time slower

  - by Fassenkugel

  I'm writing a code where: I.) The user adds "events" during run-time. (To a flowlayoutpanel) These events are turning some LEDs on/off, after "x" time has elapsed and the LED-turning functions are written in a Led-function.cs class. i.e: 1) Turn left led on After 3500ms 2) Turn right led on After 4000ms II.) When the user hits start a timer starts. // Create timer. System.Timers.Timer _timer; _timer = new System.Timers.Timer(); _timer.Interval = (1); _timer.Elapsed += (sender, e) => { HandleTimerElapsed(LedObject, device, _timer); }; _timer.Start(); III.) The timer's tick event is raised every millisecond and checks if the user definied time has ellapsed. Im measuring the elapsed time with adding +1 to an integer at every tick event. (NumberOfTicks++;) //Timer Handle private void HandleTimerElapsed(Led_Functions LedObject, string device, System.Timers.Timer _timer) { NumberOfTicks++; if (NumberOfTicks >= Start_time[0]) { LedObject.LeftLED_ONnobutton(device); } } IV.) What I noticed was that when the tick was set to 1. (So the tick event is raised every millisecond) Even if I set 3000ms to the evet the LED actually flashed around 6 seconds. When the tick was set to 100. (So every 0,1s) then the flash was more accurate (3,5sec or so). Any Ideas why im having this delay in time? Or do you have any ideas how could I implement it better? Thank you!

• What are the drawbacks of this Classing format?

  - by Keysle

  This is a 3 layer example of my classing format function __(_){return _.constructor} //class var _ = ( CLASS = function(){ this.variable = 0; this.sub = new CLASS.SUBCLASS(); }).prototype; _.func = function(){ alert('lvl'+this.variable); this.sub.func(); } _.divePeak = function(){ alert('lvl'+this.variable); this.sub.variable += 5; } //sub class _ = ( __(_).SUBCLASS = function(){ this.variable = 1; this.sub = new CLASS.SUBCLASS.DEEPCLASS(); }).prototype; _.func = function(){ alert('lvl'+this.variable); this.sub.func(); } //deep class _ = ( __(_).DEEPCLASS = function(){ this.variable = 2; }).prototype; _.func = function(){ alert('lvl'+this.variable); } Before you blow a gasket, let me explain myself. The purpose behind the underscores is to accelerate the time needed to specify functions for a class and also specify sub classes of a class. To me it's easier to read. I KNOW, this does interfere with underscore.js if you intend to use it in your classes. I'm sure _.js can be easily switched over to another $ymbol though ... oh wait, But I digress. Why have classes within a class? because solar.system() and social.system() mean two totally different things but it's convenient to use the same name. Why user underscores to manage the definition of the class? because "Solar.System.prototype" took me about 2 seconds to type out and 2 typos to correct. It also keeps all function names for all classes in the same column of texts, which is nice for legibility. All I'm doing is presenting my reasoning behind this method and why I came up with it. I'm 3 days into learning OO JS and I am very willing to accept that I might have messed up.

• Jquery + Prototype Question

  I recently inherited a site which is botched in all sorts of ways. I'm more of a php guy and initially the js was working just fine.

• How do I refer to a client_deploy.wsdd file that's in WEB-INF?

  - by Paul

  A basic question, but I can't seem to find the answer. I have an Axis-generated web service that also calls another web service (for which the stubs are also generated with Axis). It's deployed in weblogic 9.2 That called web service requires authentication. I've googled for the code to set up authentication. It requires that I set up a client_deploy.wsdd file which I've done, and added it to WEB-INF. I need to specify this flle to Axis. There seem to be several ways of doing this, including System.setProperty("axis.ClientConfigFile", "client_deploy.wsdd") or EngineConfiguration config = new FileProvider("client_deploy.wsdd"); but these aren't working for me. Is the issue the path for the client_deploy.wsdd file? How do I refer to a file that's at the top level of the WEB-INF directory? Googling tells me how to access it as a stream, but I don't want that, I need to pass a file name to these functions... Please point out the obvious that I have missed

• SQL - Query range between two dates (NON-VBA)

  - by Mohgeroth

  I see various topics on this around stack overflow but none that fit the contect of MS-Access... Given a starting date and an ending date, is there a way through SQL to return records for each given month within the time frame? EG: Between #1/1/2010# and #12/31/2010# results #1/4/2010# #1/11/2010# ..... #12/27/2010# Restrictions MS-Access 2003 :No Case/Loops inside the SQL (IIF statements are good) This is a view only, NO VBA will be used since the data will not be tampered with. Disconnected recordset is my last option. I would prefer to find out theres some way to call your customized functions in the SQL to help return these values... some class stored on a global scope while you iterate through this date range maybe... Is this possible? I see many no's, but if there was a way to pass a value into a function I could find a way to make this work. Sad that I don't have a way to simulate a stored procedure without using a d/c recordset, at least that I know of... any experts out there know a way?

• Python - How to wake up a sleeping process- multiprocessing?

  - by user1162512

  I need to wake up a sleeping process ? The time (t) for which it sleeps is calculated as t = D/S . Now since s is varying, can increase or decrease, I need to increase/decrease the sleeping time as well. The speed is received over a UDP procotol. So, how do I change the sleeping time of a process, keeping in mind the following:- If as per the previous speed `S1`, the time to sleep is `(D/S1)` . Now the speed is changed, it should now sleep for the new time,ie (D/S2). Since, it has already slept for D/S1 time, now it should sleep for D/S2 - D/S1. How would I do it? As of right now, I'm just assuming that the speed will remain constant all throughout the program, hence not notifying the process. But how would I do that according to the above condition? def process2(): p = multiprocessing.current_process() time.sleep(secs1) # send some packet1 via UDP time.sleep(secs2) # send some packet2 via UDP time.sleep(secs3) # send some packet3 via UDP Also, as in threads, 1) threading.activeCount(): Returns the number of thread objects that are active. 2) threading.currentThread(): Returns the number of thread objects in the caller's thread control. 3) threading.enumerate(): Returns a list of all thread objects that are currently active. What are the similar functions for getting activecount, enumerate in multiprocessing?

• ajax on parked domain

  - by Daryl

  I'm currently writing this jquery and for some reason (I don't know why) it works on the normal domain, but on the parked domain it doesn't. Normal domain - http://www.thefinishedbox.com Parked domain - http://www.tfbox.com If you scroll down to the colony news and hit the click me link you'll see it will retrieve data via jquery ajax on the Normal domain, but on the parked domain it wont. Here is the jQuery code I have so far (its pretty standard): $(function() { $.ajaxSetup({ cache: false }); var ajax_load = "Load me plz"; // load() functions var loadUrl = "http://thefinishedbox.com/wp-content/themes/tfbox-beta/test.php"; $('.overlay').css({ opacity: '0' }); $('.toggle').click(function() { $('.overlay').css({ display: 'block' }).animate({ opacity: '1' }, 300); $(".overlay .content").html(ajax_load).load(loadUrl); return false; }); $('.close').click(function() { $('.overlay').animate({ opacity: '0' }, 300); $('.overlay').queue(function() { $(this).css({ display: 'none' }); $(this).dequeue(); }); return false; }); I'm a complete noob when it comes to ajax so any help would be massivly appreciated.

• Getting values from another winform and passing it to current!

  - by klm9971

  Hello: I have 2 windows forms. The 1st one who gets active during start of the program has a button in which another 2nd windows form appears which has text field in which user type their name and HIT okay. Now in the 1st form I have a variable name: nameproccessed which takes the name from the second form. But the problem is my button which is in the 1st form has more functions besides taking name, how can I stop the flow of the compiler to take first the name from the second form and then process the rest execution of the function??? Here is the snippet of my code: //1st form //Class1 public string _nameProcessed = ""; private void btnGetSomething_Click(object sender, EventArgs e) { showdial(); //some more functionalities in this function!!! } private void showdial() { InputName inm = new InputName(); inm.Show(); } //2nd form //Class2 public string name; private void btnEnterName_Click(object sender, EventArgs e) { name = tbxName.Text; Class1 ict = new Class1(); ict._nameProcessed = name; this.Close(); } Now I want to take the 'name' from the second form put it on the _nameprocessed in the 1st form and then execute the rest of the function. How can I do that? Any help!

• C++ creating generic template function specialisations

  - by Fire Lancer

  I know how to specialise a template function, however what I want to do here is specialise a function for all types which have a given method, eg: template<typename T> void foo(){...} template<typename T, if_exists(T::bar)>void foo(){...}//always use this one if the method T::bar exists T::bar in my classes is static and has different return types. I tried doing this by having an empty base class ("class HasBar{};") for my classes to derive from and using boost::enable_if with boost::is_base_of on my "specialised" version. However the problem then is that for classes that do have bar, the compiler cant resolve which one to use :(. template<typename T> typename boost::enable_if<boost::is_base_of(HasBar, T>, void>::type f() {...} I know that I could use boost::disable_if on the "normal" version, however I do not control the normal version (its provided by a third party library and its expected for specialisations to be made, I just don't really want to make explicit specialisations for my 20 or so classes), nor do I have that much control over the code using these functions, just the classes implementing T::bar and the function that uses it. Is there some way to tell the compiler to "always use this version if possible no matter what" without altering the other versions?

• Is there a way to deserialize an object into "$this"?

  - by Andreas Bonini

  I'm writing a class to handle a memcached object. The idea was to create abstract class Cachable and all the cachable objects (such as User, Post, etc) would be subclasses of said class. The class offers some method such as Load() which calls the abstract function LoadFromDB() if the object is not cached, functions to refresh/invalidate the cache, etc. The main problem is in Load(); I wanted to do something similar: protected function Load($id) { $this->memcacheId = $id; $this->Connect(); $cached = $this->memcache->get(get_class($this) . ':' . $id); if($cached === false) { $this->SetLoaded(LoadFromDB($id)); UpdateCache(); } else { $this = $cached; $this->SetLoaded(true); } } Unfortunately I need $this to become $cached (the cached object); is there any way to do that? Was the "every cachable object derives from the cachable class" a bad design idea?

• Selective replication with CouchDB

  - by FRotthowe

  I'm currently evaluating possible solutions to the follwing problem: A set of data entries must be synchonized between multiple clients, where each client may only view (or even know about the existence of) a subset of the data. Each client "owns" some of the elements, and the decision who else can read or modify those elements may only be made by the owner. To complicate this situation even more, each element (and each element revision) must have an unique identifier that is equal for all clients. While the latter sounds like a perfect task for CouchDB (and a document based data model would fit my needs perfectly), I'm not sure if the authentication/authorization subsystem of CouchDB can handle these requirements: While it should be possible to restict write access using validation functions, there doesn't seem to be a way to authorize read access. All solutions I've found for this problem propose to route all CouchDB requests through a proxy (or an application layer) that handles authorization. So, the question is: Is it possible to implement an authorization layer that filters requests to the database so that access is granted only to documents that the requesting client has read access to and still use the replication mechanism of CouchDB? Simplified, this would be some kind of "selective replication" where only some of the documents, and not the whole database is replicated. I would also be thankful for directions to some detailed information about how replication works. The CouchDB wiki and even the "Definite Guide" Book are not too specific about that.

• Javascript object binding problem inside of function prototype definitions

  - by Arion

  Hi all, I am trying to figure out the right place to bind a function prototype to be called later. The full code of the example can be found here: http://www.iprosites.com/jso/ My javascript example is very basic: function Obj(width, height){ this.width = width; this.height = height; } Obj.prototype.test = function(){ var xhr=init(); xhr.open('GET', '?ajax=test', true); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8'); xhr.onreadystatechange = function() { if (xhr.responseText == '403') { window.location.reload(false); } if (xhr.readyState == 4 && xhr.status == 200) { this.response = parseResponse(xhr.responseText); document.getElementById('resp').innerHTML = this.response.return_value; this.doAnotherAction(); } }; xhr.send(); } Obj.prototype.doAnotherAction = function(){ alert('Another Action Done'); } var myo = new Obj(4, 6); If you try to run myo.test() in Firebug, you will get the "this.doAnotherAction is not a function" response. The 2 support functions init() and parseResponse() can be found in the test.js link if you wish to view them, but should not be too relevant to this problem. I've affirmed that this.doAnotherAction() thinks "this" is the XMLHttpResponse object as expected from an instanceof test. Can anyone help with some insight on direction with binding? Everything I've tried seems not to work! I do use Mootools, although the library is not present in this example. Thanks in advance, Arion

• Always send certain values with an ajax request/post

  - by DZittersteyn

  I'm building a system that displays a list of user, and on selection of a user requests some form of password. These values are saved in a hidden field on the page, and need to be sent with every request as a form of authentication. (I'm aware of the MITM-vulnerability that lies herein, but it's a very low-key system, so security is not a large concern). Now I need to send these values with each and every request, to auth the currently 'logged in' user. I'd like to automate this, via ajaxSetup, however i'm running into some issues. My first try was: init_user_auth: function(){ $.ajaxSetup({ data: { 'user' : site_user.selected_user_id(), 'passcode': site_user.selected_user_pc(), 'barcode' : site_user.selected_user_bc() } }); }, However, as I should have known, this reads the values once, at the time of the call to ajaxSetup, and never rereads them. What I need is a way to actually call the functions every time an ajax-call is made. I'm currently trying to understand what is happening here: https://groups.google.com/forum/?fromgroups=#!topic/jquery-dev/OBcEfgvTJ9I, however through the flamewar and very low-level stuff going on there, I'm not exactly sure I get what is going on. Is this the way to proceed, or should I just face facts and manually add login-info to each ajax-call?

• Getting a stream back from a .Net remoting service that is accessible with IP v4 and v6

  - by jon.ediger

  My company has an existing .Net Remoting service that listens on a port, fronting interfaces used by external systems. This all works great with IP v4 based communications. However, this service now needs to support both IP v4 communications and IP v6 communications. I have found info that the system.runtime.remoting section of the app.config should include two channels as follows: <channel ref="tcp" name="tcp6" port="9000" bindTo="[::]" /> <channel ref="tcp" name="tcp4" port="9000" bindTo="0.0.0.0" /> The above config file changes to the System.Runtime.Remoting config section will get the remoting service responding to non-stream functions on both ip v4 and ip v6. The issue comes only when attempting to get a stream back, used to upload or download large files. In this case, instead of getting a usable stream back, the following ArgumentException is thrown instead: IPv4 address 0.0.0.0 and IPv6 address ::0 are unspecified addresses that cannot be used as a target address. Parameter name: hostNameOrAddress Is there a way to modify the app.config (in the system.runtime.remoting section, or another section) so that the service will return a stream mapped to a real ip so the client can actually upload/download files while maintaining the ability to use both IP v4 and IP v6?

• Should core application configuration be stored in the database, and if so what should be done to se

  - by Rl

  I'm writing an application around a lot of hierarchical data. Currently the hierarchy is fixed, but it's likely that new items will be added to the hierarchy in the future. (please let them be leaves) My current application and database design is fairly generic and nothing dealing with specific nodes in the hierarchy is hardcoded, with the exception of validation and lookup functions written to retrieve external data from each node's particular database. This pleases me from a design point of view, but I'm nervous at the realization that the entire application rests on a handful of records in the database. I'm also frustrated that I have to enforce certain aspects of data integrity with database triggers rather than by foreign key constraints (an example is where several different nodes in the hierarchy have their own proprietary IDs and I store them in a single column which, when coupled with the node ID can be used to locate the foreign data). I'm starting to wonder whether it may have been appropriate to simply hardcoded these known nodes into the system so that it would be more "type safe" and less generic. How does one know when something should be hardcoded, and when it should be a configuration item? Is it just a cost-benefit analysis of clarity/safety now vs less work later, or am I missing some metric I should be using to determine whether or not this is appropriate. The steps I'm taking to protect these valuable configurations are to add triggers that prevent updates/deletes. The database user that this application uses will only have the ability to manipulate data through stored procedures. What else can I do?

• Modal QMessageBox does not behave like native Windows dialogs

  - by Philip Daubmeier

  My application has a dialog that asks the user via a QMessageBox whether he wants to discard all changes he made or wants to keep editing. I want this dialog to be modal to the whole application. I read somewhere that this is the standard behavior for a QMessageBox, so I dont have to set it explicitly with something like: mbox.setWindowModality(Qt::ApplicationModal); I wonder why it behaves differently from other modal dialogs in the OS (Windows 7 in my case). On the one hand it functions like it should, i.e. all other input methods in the application are blocked until the user answeres the dialog. However, it doesn't 'blink'* if the user clicks any other window of the application. Is there any way to get Qt to behave like a native Windows dialog? Thanks in advance! *If you don't know what I mean with this 'blinking': Just open notepad on a Windows OS, type some text and try to close it. A dialog pops up that asks to save, discard or keep editing. Now click somewhere on the editor window - the border and titlebar of the dialog flashes/blinks a few times.

• [c++] accessing the hidden 'this' pointer

  - by Kyle

  I have a GUI architecture wherein elements fire events like so: guiManager->fireEvent(BUTTON_CLICKED, this); Every single event fired passes 'this' as the caller of the event. There is never a time I dont want to pass 'this', and further, no pointer except for 'this' should ever be passed. This brings me to a problem: How can I assert that fireEvent is never given a pointer other than 'this', and how can I simplify (and homogenize) calls to fireEvent to just: guiManager->fireEvent(BUTTON_CLICKED); At this point, I'm reminded of a fairly common compiler error when you write something like this: class A { public: void foo() {} }; class B { void oops() { const A* a = new A; a->foo(); } }; int main() { return 0; } Compiling this will give you ../src/sandbox.cpp: In member function ‘void B::oops()’: ../src/sandbox.cpp:7: error: passing ‘const A’ as ‘this’ argument of ‘void A::foo()’ discards qualifiers because member functions pass 'this' as a hidden parameter. "Aha!" I say. This (no pun intended) is exactly what I want. If I could somehow access the hidden 'this' pointer, it would solve both issues I mentioned earlier. The problem is, as far as I know you can't (can you?) and if you could, there would be outcries of "but it would break encapsulation!" Except I'm already passing 'this' every time, so what more could it break. So, is there a way to access the hidden 'this', and if not are there any idioms or alternative approaches that are more elegant than passing 'this' every time?

• Can Drupal Taxonomy module be used to categorize court records and briefs?

  - by DKinzer

  I'm currently working on project that involves moving a database of documents for court records and briefs over to a Drupal environment. One of the problems that we are faced with is how to index these documents. In our court district, records and briefs all have a docket number which is assigned to a case. The interesting thing is that when multiple cases merge the docket numbers associated to the case become synonymous: Case 1, documents have Doceket No. A Case 2, documents have Docket No. B If case Cases 1 and Case 2 merge, then Docket No. A = Docket No. B My first inclination is to create Docket Vocabulary and have the terms of this Taxonomy be the docket numbers. I am hoping to take advantage of the fact that terms can be synonymous. I understand that there are several functions in the Taxonomy module that I may be able to take advantage, of including: taxonomy_get_synonyms taxonomy_get_related But I'm having problems convincing my collegues that this is the way to go, and frankly I'm not certain it's the right solution either. If anyone has had a similar issue and can offer some guidance as to how to move forward, I would greatly appreciate it. Thanks! D I've asked a related question (which I would also need to answer in order to move forward with this solution): http://stackoverflow.com/questions/2656247/can-drupal-terms-in-different-taxonomies-be-synonymous
