• Datagridview DateTime Format not using System Region settings

  - by Nick

  I've got a datagridview that is hooked up to a bindingsource on my main form. One of the columns and datamembers in the bindingsource is a DateTime object. When the datagridview shows this item it doesn't use Window's default region settings for displaying datetime. The weird thing is, I can access this same DateTime object and print it to a text box, or even pass it off to another form with another datagridview and binding source and it actually shows up properly in that table. So then, why does the datagridview on my main form not use the regional date/time settings when converting the DateTime object to a string? I've checked that there was no special formatting applied to the datagridview and so I'm running out of ideas to check. Do you guys know if there is any super secret way to get a datagridview to follow system regional format rules or not? Also, since I highly doubt that I did something different with this datagridview vs the others in my application, the next potential area for issue could be on application load: Perhaps since this comes up when the application loads, it's not getting the same cultureUI settings as the other datagridviews? Any Help?

• Why is an Add method required for { } initialization?

  - by Dan Tao

  To use initialization syntax like this: var contacts = new ContactList { { "Dan", "[email protected]" }, { "Eric", "[email protected]" } }; ...my understanding is that my ContactList type would need to define an Add method that takes two string parameters: public void Add(string name, string email); What's a bit confusing to me about this is that the { } initializer syntax seems most useful when creating read-only or fixed-size collections. After all it is meant to mimic the initialization syntax for an array, right? (OK, so arrays are not read-only; but they are fixed size.) And naturally it can only be used when the collection's contents are known (at least the number of elements) at compile-time. So it would almost seem that the main requirement for using this collection initializer syntax (having an Add method and therefore a mutable collection) is at odds with the typical case in which it would be most useful. I'm sure I haven't put as much thought into this matter as the C# design team; it just seems that there could have been different rules for this syntax that would have meshed better with its typical usage scenarios. Am I way off base here? Is the desire to use the { } syntax to initialize fixed-size collections not as common as I think? What other factors might have influenced the formulation of the requirements for this syntax that I'm simply not thinking of?

• How to elegantly handle ReturnUrl when using UrlRewrite in ASP.NET 2.0 WebForms

  - by Brian Kim

  I have a folder with multiple .aspx pages that I want to restrict access to. I have added web.config to that folder with <deny users="?"/>. The problem is that ReturnUrl is auto-generated with physical path to the .aspx file while I'm using UrlRewrite. Is there a way to manipulate ReturnUrl without doing manual authentication check and redirection? Is there a way to set ReturnUrl from code-behind or from web.config? EDIT: The application is using ASP.NET 2.0 WebForms. I cannot use 3.5 routing. EDIT 2: It seems like 401 status code is never captured. It returns 302 for protected page and redirects to login page with ReturnUrl. It does not return 401 for protected page. Hmm... Interesting... Ref: http://msdn.microsoft.com/en-us/library/aa480476.aspx This makes things harder... I might have to write reverse rewrite mapping rules to regex match ReturnUrl and replace it if it doesn't return 401... If it does return 401 I can either set RawUrl to Response.RedirectLocation or replace ReturnUrl with RawUrl. Anyone else have any other ideas?

• Why This Maintainability Index Increase?

  - by Timothy

  I would be appreciative if someone could explain to me the difference between the following two pieces of code in terms of Visual Studio's Code Metrics rules. Why does the Maintainability Index increase slightly if I don't encapsulate everything within using ( )? Sample 1 (MI score of 71) public static String Sha1(String plainText) { using (SHA1Managed sha1 = new SHA1Managed()) { Byte[] text = Encoding.Unicode.GetBytes(plainText); Byte[] hashBytes = sha1.ComputeHash(text); return Convert.ToBase64String(hashBytes); } } Sample 2 (MI score of 73) public static String Sha1(String plainText) { Byte[] text, hashBytes; using (SHA1Managed sha1 = new SHA1Managed()) { text = Encoding.Unicode.GetBytes(plainText); hashBytes = sha1.ComputeHash(text); } return Convert.ToBase64String(hashBytes); } I understand metrics are meaningless outside of a broader context and understanding, and programmers should exercise discretion. While I could boost the score up to 76 with return Convert.ToBase64String(sha1.ComputeHash(Encoding.Unicode.GetBytes(plainText))), I shouldn't. I would clearly be just playing with numbers and it isn't truly any more readable or maintainable at that point. I am curious though as to what the logic might be behind the increase in this case. It's obviously not line-count.

• Flex: embedded fonts not being applied correctly in Label and DataGrid

  - by lje

  Folks, I am observing a problem with how an embedded font is applied to certain Flex components, namely mx:Label and mx:DataGrid. I have a CSS that declares three variations on an embedded font as follows: @font-face { src:url("buttons.swf"); font-family: "Arial"; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-weight: bold; } @font-face { src:url("buttons.swf"); font-family: "Arial"; font-style: italic; } And in the style declaration for Label and DataGrid, I have: Label { fontFamily: "Arial"; fontSize: 11; fontFamily: LucidaSans; } and DataGrid { fontFamily: "Arial"; height: 16; } (I've snipped some stuff from both style rules, so if you think there's something that may be causing a conflict I can certainly post the entire definition. It's mostly color, line and padding stuff for the DataGrid.) The problem that is for both Label and cells in the DataGrid the text is being rendered as sort of a times new roman font. The headers in the DataGrid are fine, just the text in the cells is wonky. All other components use the correct font as defined in the CSS/SWF. Any ideas why this is happening?

• errors when using c++ bison ---- in the file position.hh

  - by Eric

  firstly I'm not good at English so forgive me. I compile my program with the bison generated files in visual studio and get these errors: ...\position.hh(83): error C2589: '(' : illegal token on right side of '::' ...\position.hh(83): error C2059: syntax error : '::' ...\position.hh(83): error C2589: '(' : illegal token on right side of '::' ...\position.hh(83): error C2059: syntax error : '::' and the corresponding code is: inline void columns (int count = 1) { column = std::max (1u, column + count); } I think the problem is with std::max. If I change std::max to equivalent code then there is problem anymore, but is there a better solution instead of changing the generated code? here is the *.yy file I wrote. // // bison.yy // %skeleton "lalr1.cc" %require "2.4.2" %defines %define parser_class_name "cmd_parser" %locations %debug %error-verbose %code requires { class ParserDriver; } %parse-param { ParserDriver& driver } %lex-param { ParserDriver& driver } %union { struct ast *a; double d; struct symbol *s; struct symlist *sl; int fn; } %code { #include "helper_func.h" #include "ParserDriver.h" std::string error_msg = ""; } %token <d> NUMBER %token <s> NAME %token <fn> FUNC %token EOL %token IF THEN ELSE WHILE DO LET %token SYM_TABLE_OVERFLOW %token UNKNOWN_CHARACTER %nonassoc <fn> CMP %right '=' %left '+' '-' %left '*' '/' %nonassoc '|' UMINUS %type <a> exp stmt list explist %type <sl> symlist %{ extern int yylex(yy::cmd_parser::semantic_type *yylval, yy::cmd_parser::location_type* yylloc); %} %start calclist %% ... grammar rules ...

• Using htaccess rewrite/redirect so single PHP file can display data according to GET/POST variables

  - by revive

  Hey gang, Bear with me as I try to learn more about .htaccess redirect rules - I'm a UI guy by profession and I'm doing my best to enhance my coding skills languages other than HTML/CSS/PHP, etc So, what I have is an index.php file that contains a menu - pretty simple. If Javascript is enabled on the users computer then forms are shown below the menu using simple jQuery goodies, with each link having a 'return false;' applied. What I am trying to do is make the page accessible with JS turned off, so instead of redirecting the user to a different page, I would like to use POST or GET variables from each link, to show the various forms.. within the same index.php file - but have the URL reflect the menu choice Here is an example using menu items named - Home, About, Form1 and Form2: With JS on, clicking on of the above example buttons simply slides the form or containing the data down onto the page. With JS off, if the user clicks the 'About' link, I would like to rewrite the URL to be http://domain.com/about - but keep the user on the index.php page (since it is the only page) and be able to use POST or GET variable to show the using PHP. So, accessing http://domain.com/index.php?page=about would show http://domain.com/about in the URL but pass the GET variable 'page' to the index.php file. Hope that makes sense.. and I'm sure there are many ways to accomplish this, so if you have ideas of how to improve on it, by all means, I'd love to hear it ! Thanks again Revive

• Need some advice on Core Data modeling strategy

  - by Andy

  I'm working on an iPhone app and need a little advice on modeling the Core Data schema. My idea is a utility that allows the user to speed-dial their contacts using user-created rules based on the time of day. In other words, I would tell the app that my wife is commuting from 6am to 7am, at work from 7am to 4pm, commuting from 4pm to 5pm, and home from 5pm to 6am, Monday through Friday. Then, when I tap her name in my app, it would select the number to dial based on the current day and time. I have the user interface nearly complete (thanks in no small part to help I've received here), but now I've got some questions regarding the persistent store. The user can select start- and stop-times in 5-minute increments. This means there are 2,016 possible "time slots" in week (7 days * 24 hours * 12 5-minute intervals per hour). I see a few options for setting this up. Option #1: One array of time slots, with 2,016 entries. Each entry would be a dictionary containing a contact identifier and an associated phone number to dial. I think this means I'd need a "Contact" entity to store the contact information, and a "TimeSlot" entity for each of the 2,016 possible time slots. Option #2: Each Contact has its own array of time slots, each with 2,016 entries. Each array entry would simply be a string indicating which phone number to dial. Option #3: Each Contact has a dictionary of time slots. An entry would only be added to the dictionary for time slots with an active rule. If a search for, say, time slot 1,299 (Friday 12:15pm) didn't find a key @"1299" in the dictionary, then a default number would be dialed instead. I'm not sure any of these is the "right" way or the "best" way. I'm not even sure I need to use Core Data to manage it; maybe just saving arrays would be simpler. Any input you can offer would be appreciated.

• How do I correctly use Unity to pass a ConnectionString to my repository classes?

  - by GenericTypeTea

  I've literally just started using the Unity Application Blocks Dependency Injection library from Microsoft, and I've come unstuck. This is my IoC class that'll handle the instantiation of my concrete classes to their interface types (so I don't have to keep called Resolve on the IoC container each time I want a repository in my controller): public class IoC { public static void Intialise(UnityConfigurationSection section, string connectionString) { _connectionString = connectionString; _container = new UnityContainer(); section.Configure(_container); } private static IUnityContainer _container; private static string _connectionString; public static IMovementRepository MovementRepository { get { return _container.Resolve<IMovementRepository>(); } } } So, the idea is that from my Controller, I can just do the following: _repository = IoC.MovementRepository; I am currently getting the error: Exception is: InvalidOperationException - The type String cannot be constructed. You must configure the container to supply this value. Now, I'm assuming this is because my mapped concrete implementation requires a single string parameter for its constructor. The concrete class is as follows: public sealed class MovementRepository : Repository, IMovementRepository { public MovementRepository(string connectionString) : base(connectionString) { } } Which inherits from: public abstract class Repository { public Repository(string connectionString) { _connectionString = connectionString; } public virtual string ConnectionString { get { return _connectionString; } } private readonly string _connectionString; } Now, am I doing this the correct way? Should I not have a constructor in my concrete implementation of a loosely coupled type? I.e. should I remove the constructor and just make the ConnectionString property a Get/Set so I can do the following: public static IMovementRepository MovementRepository { get { return _container.Resolve<IMovementRepository>( new ParameterOverrides { { "ConnectionString", _connectionString } }.OnType<IMovementRepository>() ); } } So, I basically wish to know how to get my connection string to my concrete type in the correct way that matches the IoC rules and keeps my Controller and concrete repositories loosely coupled so I can easily change the DataSource at a later date.

• Simple CalendarStore query puts application into infinite loop!?

  - by Frank R.

  Hi, I've been looking at adding iCal support to my new application and everything seemed just fine and worked on my Mac OS X 10.6 Snow Leopard development machine without a hitch. Now it looks like depending on what is in your calendar the very simple query below: - (NSArray*) fetchCalendarEventsForNext50Minutes { NSLog(@"fetchCalendarEventsForNext50Minutes"); NSTimeInterval start = [NSDate timeIntervalSinceReferenceDate]; NSDate* startDate = [[NSDate alloc] init]; NSDate* endDate = [startDate addTimeInterval: 50.0 * 60.0]; NSPredicate *eventsForTheNext50Minutes = [CalCalendarStore eventPredicateWithStartDate:startDate endDate:endDate calendars:[[CalCalendarStore defaultCalendarStore] calendars]]; // Fetch all events for this year NSArray *events = [[CalCalendarStore defaultCalendarStore] eventsWithPredicate: eventsForTheNext50Minutes]; NSLog( @"fetch took: %f seconds", [NSDate timeIntervalSinceReferenceDate] - start ); return events; } produces a beachball thrash even with quite limited events in the calendar store. Am I missing something crucial here? The code snippet is pretty much exactly from the documentation at: // Create a predicate to fetch all events for this year NSInteger year = [[NSCalendarDate date] yearOfCommonEra]; NSDate *startDate = [[NSCalendarDate dateWithYear:year month:1 day:1 hour:0 minute:0 second:0 timeZone:nil] retain]; NSDate *endDate = [[NSCalendarDate dateWithYear:year month:12 day:31 hour:23 minute:59 second:59 timeZone:nil] retain]; NSPredicate *eventsForThisYear = [CalCalendarStore eventPredicateWithStartDate:startDate endDate:endDate calendars:[[CalCalendarStore defaultCalendarStore] calendars]]; // Fetch all events for this year NSArray *events = [[CalCalendarStore defaultCalendarStore] eventsWithPredicate:eventsForThisYear]; It looks like it has something to do with the recurrence rules, but as far as I can see there are no other ways of fetching events from the calendar store anyway. Has anybody else come across this? Best regards, Frank

• Makefile trickery using VPATH and include.

  - by roe

  Hi, I'm playing around with make files and the VPATH variable. Basically, I'm grabbing source files from a few different places (specified by the VPATH), and compile them into the current directory using simply a list of .o-files that I want. So far so good, now I'm generating dependency information into a file called '.depend' and including that. Gnumake will attempt to use the rules defined so far to create the included file if it doesn't exist, so that's ok. Basically, my makefile looks like this. VPATH=A/source:B/source:C/source objects=first.o second.o third.o executable: $(objects) .depend: $(objects:.o=.c) $(CC) -MM $^ > $@ include .depend Now for the real question, can I suppress the generation of the .depend file in any way? I'm currently working in a clearcase environment - sloooow, so I'd prefer to have it a bit more under control when to update the dependency information. It's more or less an academic exercise as I could just wrap the thing in a script which is touching the .depend file before executing make (thus making it more recent than any source file), but it'd interesting to know if I can somehow suppress it using 'pure' make. I cannot remove the dependency to the source files (i.e. using simply .depend:), as I'm depending on the $^ variable to do the VPATH resolution for me. If there'd be any way to only update dependencies as a result of updated #include directives, that'd be even better of course.. But I'm not holding my breath for that one.. :)

• rails HABTM versus view (formtastic)

  - by VP

  I have two models: The model NetworkObject try to describe "hosts". I want to have a rule with source and destination, so i'm trying to use both objects from the same class since it dont makes sense to create two different classes. class NetworkObject < ActiveRecord::Base attr_accessible :ip, :netmask, :name has_many :statements has_many :rules, :through =>:statements end class Rule < ActiveRecord::Base attr_accessible :active, :destination_ids, :source_ids has_many :statements has_many :sources, :through=> :statements, :source=> :network_object has_many :destinations, :through => :statements, :source=> :network_object end To build the HABTM i did choose the Model JOIN. so in this case i created a model named Statement with: class Statement < ActiveRecord::Base attr_accessible :source_id, :rule_id, :destination_id belongs_to :network_object, :foreign_key => :source_id belongs_to :network_object, :foreign_key => :destination_id belongs_to :rule end The problem is: is right to add two belongs_to to the same class using different foreign_keys? I tried all combinations like: belongs_to :sources, :class_name => :network_object, :foreign_key => :source_id but no success.. anything that i am doing wrong?

• jQuery Validation error...

  - by Povylas

  Hi, I have been struggling with this jQuery Validation Plugin. Here is the code: <script type="text/javascript"> $(function() { var validator = $('#signup').validate({ errorElement: 'span', rules: { username: { required: true, minlenght: 6 //remote: "check-username.php" }, password: { required: true, minlength: 5 }, confirm_password: { required: true, minlength: 5, equalTo: "#password" }, email: { required: true, email: true }, agree: "required" }, messages: { username: { required: "Please enter a username", minlength: "Your username must consist of at least 6 characters" //remote: "Somenoe have already chosen nick like this." }, password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long" }, confirm_password: { required: "Please provide a password", minlength: "Your password must be at least 5 characters long", equalTo: "Please enter the same password as above" }, email: "Please enter a valid email address", agree: "Please accept our policy" } }); var root = $("#wizard").scrollable({size: 1, clickable: false}); // some variables that we need var api = root.scrollable(); $("#data").click(function() { validator.form(); }); // validation logic is done inside the onBeforeSeek callback api.onBeforeSeek(function(event, i) { if($("#signup").valid() == false){ return false; }else{ return true; } $("#status li").removeClass("active").eq(i).addClass("active"); }); //if tab is pressed on the next button seek to next page root.find("button.next").keydown(function(e) { if (e.keyCode == 9) { // seeks to next tab by executing our validation routine api.next(); e.preventDefault(); } }); $('button.fin').click(function(){ parent.$.fn.fancybox.close() }); }); </script> And here is the error: $.validator.methods[method] is undefined http://www.vvv.vhost.lt/js/jquery-validate/jquery.validate.min.js Line 15 I am completely confused... Maybe some kind of handler is needed? I would be grateful for any kind of answer.

• Python minidom and UTF-8 encoded XML with hash references

  - by Jakob Simon-Gaarde

  Hi I am experiencing some difficulty in my home project where I need to parse a SOAP request. The SOAP is generated with gSOAP and involves string parameters with special characters like the danish letters "æøå". gSOAP builds SOAP requests with UTF-8 encoding by default, but instead of sending the special chatacters in raw format (ie. bytes C3A6 for the special character "æ") it sends what I think is called character hash references (ie. &#195;&#166;). I don't completely understand why gSOAP does it this way as I can see that it has marked the incomming payload as being UTF-8 encoded anyway (Content-Type: text/xml; charset=utf-8), but this is besides the question (I think). Anyway I guess gSOAP probably is obeying transport rules, or what? When I parse the request from gSOAP in python with xml.dom.minidom.parseString() I get element values as unicode objects which is fine, but the character hash references are not decoded as UTF-8 character codes. It unescapes the character hash references, but does not decode the string afterwards. In the end I have a unicode string object with UTF-8 encoding: So if the string "æble" is contained in the XML, it comes like this in the request: "&#195;&#166;ble" After parsing the XML the unicode string in the DOM Text Node's data member looks like this: u'\xc3\xa6ble' I would expect it to look like this: u'\xe6ble' What am I doing wrong? Should I unescape the SOAP XML before parsing it, or is it somewhere else I should be looking for the solution, maybe gSOAP? Thanks in advance. Best regards Jakob Simon-Gaarde

• Javascript/PHP and timezones

  - by James

  Hi, I'd like to be able to guess the user's timezone offset and whether or not daylight savings is being applied. Currently, the most definitive code that I've found for this is here: http://www.michaelapproved.com/articles/daylight-saving-time-dst-detect/ So this gives me the offset along with the DST indicator. Now, I want to use these in my PHP scripts in order to ouput the local date/time for the user....but what's best for this? I figure I have 2 options: a) Pick a random timezone which has the same offset and DST setting from the output of timezone_abbreviations_list(). Then call date_timezone_set() with this in order to apply the correct treatment to the time. b) Continue treating the date as UTC but just do some timestamp addition to add the appropriate number of hours on. My feeling is that option B is the best way. The reason for this is that with A, I could be using a timezone which although correct in terms of offset/dst, may have some obscur rules in place behind the scene that could give surprising results (I don't know of any but nonetheless I don't think I can rule it out). I'd then re-check the timezone using Javascript at the start of each session in order to capture when either the user's timezone changes (very unlikely) or they pass in to the DST period. Sorry for the brain dump - I'm really just after some sort of reassurance that the approaches above are valid. Thanks, James.

• jQuery validate plugin against custom jQueryUI datePickers

  - by Enrique

  I have some datePickers I've customized these so they show only month and year This is the code to create them jQuery("input[name*='fechauso']").each(function() { jQuery(this).datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, dateFormat: 'MM yy', constrainInput: true, showOn: 'button', buttonText: 'Seleccionar...', onClose: function(dateText, inst) { var month = jQuery("#ui-datepicker-div .ui-datepicker-month :selected").val(); var year = jQuery("#ui-datepicker-div .ui-datepicker-year :selected").val(); jQuery(this).datepicker('setDate', new Date(year, month, 1)); } }); }); Now I've added a custom validator method (using plugin) to check this: If user didn't select a date using the button, field is empty, so the custom validator method should fire. This doesn't happen. Here is the custom validate method jQuery.validator.addMethod("isEmpty", function(value, element) { return (value == ''); }, "Must select a date with the button besides control"); jQuery("#ct_2_fechauso").rules("add", { required: "#campotilde_psico:checked", isEmpty: true }); The problem is that even if I select a date, it always ask me to select a date again. datePicker fields should be readonly

• Generate number sequences with LINQ

  - by tanascius

  I try to write a LINQ statement which returns me all possible combinations of numbers (I need this for a test and I was inspired by this article of Eric Lippert). The method's prototype I call looks like: IEnumerable<Collection<int>> AllSequences( int start, int end, int size ); The rules are: all returned collections have a length of size number values within a collection have to increase every number between start and end should be used So calling the AllSequences( 1, 5, 3 ) should result in 10 collections, each of size 3: 1 2 3 1 2 4 1 2 5 1 3 4 1 3 5 1 4 5 2 3 4 2 3 5 2 4 5 3 4 5 Now, somehow I'd really like to see a pure LINQ solution. I am able to write a non LINQ solution on my own, so please put no effort into a solution without LINQ. My tries so far ended at a point where I have to join a number with the result of a recursive call of my method - something like: return from i in Enumerable.Range( start, end - size + 1 ) select BuildCollection(i, AllSequences( i, end, size -1)); But I can't manage it to implement BuildCollection() on a LINQ base - or even skip this method call. Can you help me here?

• Code Golf: Shortest Turing-complete interpreter.

  - by ilya n.

  I've just tried to create the smallest possible language interpreter. Would you like to join and try? Rules of the game: You should specify a programming language you're interpreting. If it's a language you invented, it should come with a list of commands in the comments. Your code should start with example program and data assigned to your code and data variables. Your code should end with output of your result. It's preferable that there are debug statements at every intermediate step. Your code should be runnable as written. You can assume that data are 0 and 1s (int, string or boolean, your choice) and output is a single bit. The language should be Turing-complete in the sense that for any algorithm written on a standard model, such as Turing machine, Markov chains, or similar of your choice, it's reasonably obvious (or explained) how to write a program that after being executred by your interpreter performs the algorithm. The length of the code is defined as the length of the code after removal of input part, output part, debug statements and non-necessary whitespaces. Please add the resulting code and its length to the post. You can't use functions that make compiler execute code for you, such as eval(), exec() or similar.

• Building an *efficient* if/then interface for non-technical users to build flow-control in PHP

  - by Brendan

  I am currently building an internal tool to be used by our management to control the flow of traffic. I have built an if/then interface allowing the user to set conditions for certain outcomes, however it is inefficient to use the switch statement to control the flow. How can I improve the efficiency of my code? Example of code: if($previous['route_id'] == $condition['route_id'] && $failed == 0) //if we have not moved on to a new set of rules and we haven't failed yet { switch($condition['type']) { case 0 : $type = $user['hour']; break; case 1 : $type = $user['location']['region_abv']; break; case 2 : $type = $user['referrer_domain']; break; case 3 : $type = $user['affiliate']; break; case 4 : $type = $user['location']['country_code']; break; case 5 : $type = $user['location']['city']; break; } $type = strtolower($type); $condition['value'] = strtolower($condition['value']); switch($condition['operator']) { case 0 : if($type == $condition['value']); else $failed = '1'; break; case 1 : if($type != $condition['value']); else $failed = '1'; break; case 2 : if($type > $condition['value']); else $failed = '1'; break; case 3 : if($type >= $condition['value']); else $failed = '1'; break; case 4 : if($type < $condition['value']); else $failed = '1'; break; case 5 : if($type <= $condition['value']); else $failed = '1'; break; } }

  hi, I am building a DMS for our intranet and use a taxonomy hierarchy because we need access control that way. All company locations manage (upload,edit) their own documents but should be able to access all. This is inherited to the child terms and works fine. Additionally we want simple 3-step workflow (draft,published,archived). So i introduced roles for editor, publisher and docadmin and set permissions for the transitions. Also triggers to effectivly (un)publish documents. But (of course) a user of role publisher can do the transition for ALL documents. But we want publisher for each company location (top taxonomy level, see above). Could this be achieved? Do i have to set it up by myself (i guess "rules" is appropriate to do this) or is there another module helping. role inheritance was a guess, but that is only about roles (naturally). "module grants" i use and checked first option. That way my thoughts are going. I hope you get my idea resp. problem. drupal 6.16 current edit: I reread the docs and found ie. http://drupal.org/node/408018 Revisioning for categorized content. Will reread that.

• Is it possible to implement an infinite IEnumerable without using yield with only C# code?

  - by sinelaw

  Edit: Apparently off topic...moving to Programmers.StackExchange.com. This isn't a practical problem, it's more of a riddle. Problem I'm curious to know if there's a way to implement something equivalent to the following, but without using yield: IEnumerable<T> Infinite<T>() { while (true) { yield return default(T); } } Rules You can't use the yield keyword Use only C# itself directly - no IL code, no constructing dynamic assemblies etc. You can only use the basic .NET lib (only mscorlib.dll, System.Core.dll? not sure what else to include). However if you find a solution with some of the other .NET assemblies (WPF?!), I'm also interested. Don't implement IEnumerable or IEnumerator. Notes The closest I've come yet: IEnumerable<int> infinite = null; infinite = new int[1].SelectMany(x => new int[1].Concat(infinite)); This is "correct" but hits a StackOverflowException after 14399 iterations through the enumerable (not quite infinite). I'm thinking there might be no way to do this due to the CLR's lack of tail recursion optimization. A proof would be nice :)

• Syncing two separate structures to the same master data

  - by Mike Burton

  I've got multiple structures to maintain in my application. All link to the same records, and one of them could be considered the "master" in that it reflects actual relationships held in files on disk. The other structures are used to "call out" elements of the main design for purchase and work orders. I'm struggling to come up with a pattern that deals appropriately with changes to the master data. As an example, the following trees might refer to the same data: A |_ B |_ C |_ D |_ E |_ B |_ C |_ D A |_ B E C |_ D A |_ B C D E These secondary structures follow internal rules, but their overall structure is usually user-determined. In all cases (including the master), any element can be used in multiple locations and in multiple trees. When I add a child to any element in the tree, I want to either automatically build the secondary structure for each instance of the "master" element or at least advertise the situation to the user and allow them to manually generate the data required for the secondary trees. Is there any pattern which might apply to this situation? I've been treating it as a view problem, but it turns out to be more complicated than that when you look at the initial generation of the data.

• jQuery working in everything but IE7. (checked my commas)

  - by deadlyhifi

  The following code works in IE8, FF, Safari, Chrome etc. (not bothering with IE6 for this one), but doesn't work in IE7. I've been through the code with a fine tooth-comb. Checked the commas, messed around with ; but it's not going anywhere. I'm using the jQuery Validate and Uploadify scripts. Can anyone see the problem here? Thanks. <script type="text/javascript"> jQuery(document).ready(function($) { $("#validateform").validate({ errorClass: 'invalid', rules: { bike_url: { required: true, url: true } } }) $("#uploadify").uploadify({ 'uploader' : '<?php echo $url . '/wp-content/plugins/biketest/includes/uploadify/uploadify.swf'; ?>', 'script' : '<?php echo $url . '/wp-content/plugins/biketest/class/class.uploadify.php'; ?>', 'folder' : '<?php echo $url . '/wp-content/plugins/biketest/uploads'; ?>', 'cancelImg' : '<?php echo $url . '/wp-content/plugins/biketest/includes/uploadify/cancel.png'; ?>', 'auto' : true, 'fileDesc' : '.jpg or .png files only please.', 'fileExt' : '*.jpg;*.jpeg;*.png;', 'sizeLimit' : '2097152', 'buttonText': 'Choose Image', 'scriptData': { 'random': '<?php $rand = rand(0, 999999); echo $rand ?>' }, 'onComplete': function(event, queueID, fileObj, response, data) { var image = '<?php echo $rand; ?>-' + ((fileObj.name).toLowerCase()).replace(' ', ''); setTimeout(function(){ $(".uploaded").attr('src', '<?php echo $url; ?>/wp-content/plugins/biketest/uploads/s-' + image); }, 500); $("[name=bike_img]").val(image); } }) }); </script>

• Apache mod_rewrite RewriteCond to by-pass static resources not working

  - by d11wtq

  I can't for the life of me fathom out why this RewriteCond is causing every request to be sent to my FastCGI application when it should in fact be letting Apache serve up the static resources. I've added a hello.txt file to my DocumentRoot to demonstrate. The text file: ls /Sites/CioccolataTest.webapp/Contents/Resources/static hello.txt` The VirtualHost and it's rewrite rules: AppClass /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest -port 5065 FastCgiExternalServer /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi -host 127.0.0.1:5065 <VirtualHost *:80> ServerName cioccolata-test.webdev DocumentRoot /Sites/CioccolataTest.webapp/Contents/Resources/static RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest.fcgi/$1 [QSA,L] </VirtualHost> Even with the -f, Apache is directing requests for this text file (i.e. access http://cioccolata-test.webdev/hello.txt returns my app, not the text file). As a proof of concept I changed the RewriteCond to: RewriteCond %{REQUEST_URI} !^/hello.txt That made it serve the text file correctly and allowed every other request to hit the FastCGI application. Why doesn't my original version work? I need to tell apache to serve every file in the DocumentRoot as a static resource, but if the file doesn't exist it should rewrite the request to my FastCGI application. NOTE: The running FastCGI application is at /Sites/CioccolataTest.webapp/Contents/MacOS/CioccolataTest (without the .fcgi prefix)... the .fcgi prefix is only being used to tell the fastcgi module to direct the request to the app.
