• jQuery - hide if previous element has a particular class

  - by Tillebeck

  Hi I would like to hide all class="csc-content" where previous sibling is a h4 class="faq". UPDATE Error: I think this is wrong... the previous sibling is not h4. But I hope you get the point that all "answer" shall be hidden if the "question" has the class "faq" /UPDATE This is the html: <div id="centerCol-1"> <div id="c65" class="csc-default normal"> <div class="csc-header csc-header-n1"><h4 class="faq">FAQ question1</h4></div> <div class="csc-content active"><p class="bodytext">Answer1</p></div> </div> <div id="c67" class="csc-default normal"> <div class="csc-header csc-header-n2"><h4 class="faq">FAQ question2</h4></div> <div class="csc-content active"><p class="bodytext">Answer2</p></div> </div> <div id="c68" class="csc-default normal"> <div class="csc-header csc-header-n3"><h4>not FAQ</h4></div> <div class="csc-content active"><p class="bodytext">Not an answer, just normal content</p></div> </div> </div> jQuery should be something like: // find all outer divs with class csc-default in the div centerCol-1 // test if they contain a header div with an h4 class faq // go to next element and hide it. Error... this should be parents next element? $("#centerCol-1 .csc-default").find("h4").is(".faq").next(".csc-content").hide(); BR. Anders

• Saving and retrieving image in SQL database from C# problem

  - by Mobin

  I used this code for inserting records in a person table in my DB System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); this.personTableAdapter1.Insert(NIC_Box.Text.Trim(), Application_Box.Text.Trim(), Name_Box.Text.Trim(), Father_Name_Box.Text.Trim(), DOB_TimePicker.Value.Date, Address_Box.Text.Trim(), City_Box.Text.Trim(), Country_Box.Text.Trim(), ms.GetBuffer()); but when i retrieve this with this code byte[] image = (byte[])Person_On_Application.Rows[0][8]; MemoryStream Stream = new MemoryStream(); Stream.Write(image, 0, image.Length); Bitmap Display_Picture = new Bitmap(Stream); Image_Box.Image = Display_Picture; it works perfectly fine but if i update this with my own generated Query like System.IO.MemoryStream ms = new System.IO.MemoryStream(); Image img = Image_Box.Image; img.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); Query = "UPDATE Person SET Person_Image ='"+ms.GetBuffer()+"' WHERE (Person_NIC = '"+NIC_Box.Text.Trim()+"')"; the next time i use the same code for retrieving the image and displaying it as used above . Program throws an exception

• DVCS with a Windows central repository

  - by Mikko Rantanen

  We are currently using VSS for version control. Quite few of our developers are interested in a distributed model (And want to get rid of VSS). Our network is full of Windows machines and while our IT department has experience maintaining Linux machines they would prefer not to. What DVCS systems can host their central repository on Windows while providing.. Push access to the repository. Basic authentication. Mostly just a way to allow or deny access to the whole repository. No need for fine grained access. Server process so users don't need write right to the repository reducing the risk of accidentally messing with it. On the client side a GUI such as Tortoise would be more or less a requirement (Sorry, Windows shell sucks. :|). Ease of installation would be a huge plus as our IT department is already quite low on resources. And using windows credentials for authentication would be an advantage but not a requirement as long as the client is able to store the credentials. I have had a (really) quick look at Git, Mercurial and Bazaar. Git seemed to use ssh or simple WebDAV for repository access, requiring write permission for the users. Mercurial had a built in http server, but this seemed to be only for pull purposes. Update: Mercurial supports push as well. Bazaar Seemed to use sftp for repository access, again requiring a write permission for the users. Are there windows server processes for any DVCS systems and has anyone managed to set one up in a Windows land? And apologies if this is a duplicate question. I couldn't find one. Update Got Mercurial working for push purposes! Detailed list what was required can be found as an answer below.

• php - replace array elements with another array's elements?

  - by Simpson88Keys

  Not sure how to go about this... But, I have two arrays, one with updated information, another with outdated information... There are a lot more elements in the second array, but I'm looking to "update" the outdated one with the updated information. Here's what the arrays look like: //Outdated Array ( [0] => Array ( [anum] => 3236468462 [cid] => 4899097762 [mid] => 1104881401 [na_title] => [na_fname] => JOHN [m_initial] => [na_lname] => DOE [na_suffix] => [na_addr1] => 1234 SAMPLE AVENUE [na_addr2] => [na_city] => NORWALK [state] => OH [zip] => [zip_plus_4] => [route] => R002 [dma_code] => 510334 ) ) //Updated Array ( [1] => Array ( [0] => YUD990 [1] => 98 [2] => 1234 Sample Avenue [3] => [4] => Norwalk [5] => OH [6] => 44857-9215 [7] => 3236468462 ) ) To clarify, I want to: (1) Match up the value for [7] from the updated array with the value for [anum] in the outdated array, and then update [na_addr1], [na_addr2], [na_city], [state], [zip], [zip_plus_4] in the outdated array with the values for [2],[3],[4],[5],[6] (I know I'll need to split the updated [6] in order to get it to map corrected to the outdated) Feel like I'm making this very confusing... sorry about that...

• Making RDoc Ruby Gem Default on Mac OS X

  - by jkale

  Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns: RDoc V1.0.1 - 20041108 I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here. Cheers! Update: Running "gem list -d --version 1.0.1 rdoc" returns: *** LOCAL GEMS *** rdoc (2.4.3) Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss Rubyforge: http://rubyforge.org/projects/rdoc Homepage: http://rdoc.rubyforge.org Installed at: /usr/local/lib/ruby/gems/1.8 RDoc is an application that produces documentation for one or more Ruby source files Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version. Update 2: I found out, using: `bash --debugger rdoc` that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH `export PATH=/usr/local/lib/ruby/gems/1.8/gems/` I now have a fresh working copy of the latest RDoc!

• EF Forced Concurrency Checks

  - by Imran

  Hi, I have an issue with EF 4.0 that I hope someone can help with. I currently have an entity that I want to update in a last in wins fashion (i.e. ignore concurrency checks and just overwrite whats in the db with what is submitted). It seems Entity Framework not only includes the primary key of the entity in the where clause of the generated sql, but also any foreign key fields. This is annoying as it means that I don't get true last in wins semantics and need to know what value the fk field had before the update or I get a concurrency exception. I am aware that this can be short circuited by including a foreign key field as well as the navigation property on the entity. I would like to avoid this if possible as it's not a very clean solution. I was just wondering if there was any other way to override this behaviour? It seems like more of a bug than a feature. I have no problem with ef doing concurrency checks if I instruct it to do so but not being able to bypass concurrency completely is a bit of a hindrance as there are many valid scenarios where this is not needed

• Generate an ID via COM interop

  - by Erik van Brakel

  At the moment, we've got an unmaintanable ball of code which offers an interface to a third party application. The third party application has a COM assembly which MUST be used to create new entries. This process involves two steps: generate a new object (basically an ID), and update that object with new field values. Because COM interop is so slow, we only use that to generate the ID (and related objects) in the database. The actual update is done using a regular SQL query. What I am trying to figure out if it's possible to use NHibernate to do some of the heavy lifting for us, without bypassing the COM assembly. Here's the code for saving something to the database as I envision it: using(var s = sessionFactory.OpenSession()) using(var t = s.BeginTransaction()) { MyEntity entity = new MyEntity(); s.Save(entity); t.Commit(); } Regular NH code I'd say. Now, this is where it gets tricky. I think I have to supply my own implementation of NHibernate.Id.IIdentifierGenerator which calls the COM assembly in the Generate method. That's not a problem. What IS a problem is that the COM assembly requires initialisation, which does take a bit of time. It also doesn't like multiple instances in the same process, for some reason. What I would like to know is if there's a way to properly access an external service in the generator code. I'm free to use any technique I want, so if it involves something like an IoC container that's no problem. The thing I am looking for is where exactly to hook-up my code so I can access the things I need in my generator, without having to resort to using singletons or other nasty stuff.

• jqueryvalidation no space customization

  - by Ken

  i have a form where the user can update his name and last name. i use jquery validation to validate the form. how can i validate if the user put spaces? here's what i have: <script> $(document).ready(function(){ $('#submit').click(function() { var valid = $("#myform").valid(); if(!valid) { return false; } $.ajax({ type: "POST", url: 'save', data: $('#myform').serialize(), dataType: 'json', cache: false, success: function(result) { // redirect to another page } }); }); }); </script> </head> <body> <form id="myform" method="post" action=""> <fieldset> <legend>update name</legend> <p> <label for="fname">Name</label> <em>*</em><input id="fname" name="fname" size="25" class="required" minlength="2" /> </p> <p> <label for="lname">Last Name</label> <em>*</em><input id="lname" name="lname" size="25" class="required" minlength="2" /> </p> <p> <input id="submit" type="submit" value="Submit"/> </p> </fieldset> </form> thanks

• PHP Post Count in Forum

  - by Chris

  I'm currently desiging a forum application, I considered using a premade but decided against it as it's useful for me to learn some of the techniques. So I've written a fairly full featured forum... great. One of the problems I want to solve is to include user data for each post, at the minute the post table includes the poster ID (obviously) and I added the poster's username at a later date so I didn't have to query the User DB for X number of posts in a thread. However, it's become apparent I now want to do this, usernames don't need to update retrospectively, however avatars, sigs, and especially post counts need to update actively, so data in some form needs keeping up to date somewhere... What would be a good way of implementing this? I obviously don't want to include any more user data on the Posts DB table than necessary, but I'm struggling to find an easy way to do this short of querying the DB for each post in a thread, which is potentially going to create a lot of traffic. How have other people solved this, I've been examining the code on some other open source apps but I can't find what I'm looking for. Is it possible to select multiple records in one query? In which case I could build an array dynamically on each page request (eg 'SQL blah blah' then a for each loop to insert the ID's). Could I join the tables each time? Do I submit a query for each post? Hmm.

• ways to avoid global temp tables in oracle

  - by Omnipresent

  We just converted our sql server stored procedures to oracle procedures. Sql Server SP's were highly dependent on session tables (INSERT INTO #table1...) these tables got converted as global temporary tables in oracle. We ended up with aroun 500 GTT's for our 400 SP's Now we are finding out that working with GTT's in oracle is considered a last option because of performance and other issues. what other alternatives are there? Collections? Cursors? Our typical use of GTT's is like so: Insert into GTT INSERT INTO some_gtt_1 (column_a, column_b, column_c) (SELECT someA, someB, someC FROM TABLE_A WHERE condition_1 = 'YN756' AND type_cd = 'P' AND TO_NUMBER(TO_CHAR(m_date, 'MM')) = '12' AND (lname LIKE (v_LnameUpper || '%') OR lname LIKE (v_searchLnameLower || '%')) AND (e_flag = 'Y' OR it_flag = 'Y' OR fit_flag = 'Y')); Update the GTT UPDATE some_gtt_1 a SET column_a = (SELECT b.data_a FROM some_table_b b WHERE a.column_b = b.data_b AND a.column_c = 'C') WHERE column_a IS NULL OR column_a = ' '; and later on get the data out of the GTT. These are just sample queries, in actuality the queries are really complext with lot of joins and subqueries. I have a three part question: Can someone show how to transform the above sample queries to collections and/or cursors? Since with GTT's you can work natively with SQL...why go away from the GTTs? are they really that bad. What should be the guidelines on When to use and When to avoid GTT's

• Re-tweets and replies with JTwitter

  - by Samuh

  I have not used Twitter enough to become familiar with its terminology or the way it works, so please help me in understanding the problem I have at hand. I am getting last 20 status updates posted by some Twitter user via RSS feed, the feed XML is parsed and the statuses are displayed in a ListView. Which means that I have the original tweet in a String variable(row of ListView). When I click a ListView item, I get the option of "Re-tweeting" and "post reply". As, I understand it, when re-tweeting I will have to just update my *status* as: RT @orig-poster <original tweet> and when posting a reply I will have to just update my status as: @orig-poster <my tweet> I skimmed through the JavaDocs of the Jwitter library(Twitter class) and found a setStatus(String) method. I dont think I will have to make use of retweet() or reply() functions of the Twitter class in JTwitter library. Is my understanding correct? Please correct me if I am wrong here or missing anything. Thanks!

• Delphi Unicode String Type Stored Directly at its Address (or "Unicode ShortString")

  - by Andreas Rejbrand

  I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer (or a single byte would be enough, actually) containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). Update: The most important reason for this is probably that it would be very problematic if sizeof(string) were variable. I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right? Update I will, among other things, need to use these strings in packed records. I also need manually to read/write these strings to files/the heap. I could live with fixed-size strings, such as <= 128 characters, and I could redesign the problem so it will work with null-terminated strings. But PChar will not work, for sizeof(PChar) = 1 - it's merely an address. The approach I eventually settled for was to use a static array of bytes. I will post my implementation as a solution later today.

• Java: Infinite loop using Scanner in.hasNextInt()

  - by Tomek

  Hi everyone, I am using the following code: while (invalidInput) { // ask the user to specify a number to update the times by System.out.print("Specify an integer between 0 and 5: "); if (in.hasNextInt()) { // get the update value updateValue = in.nextInt(); // check to see if it was within range if (updateValue >= 0 && updateValue <= 5) { invalidInput = false; } else { System.out.println("You have not entered a number between 0 and 5. Try again."); } } else { System.out.println("You have entered an invalid input. Try again."); } } However, if I enter a 'w' it will tell me "You have entered invalid input. Try Again." and then it will go into an infinite loop showing the text "Specify an integer between 0 and 5: You have entered an invalid input. Try again." Why is this happening? Isn't the program supposed to wait for the user to input and press enter each time it reaches the statement: if (in.hasNextInt()) Thanks in advance, Tomek

• How can I format the text in a databound TextBox?

• Insert a datetime value with GetDate() function to a SQL server (2005) table?

  - by David.Chu.ca

  I am working (or fixing bugs) on an application which was developed in VS 2005 C#. The application saves data to a SQL server 2005. One of insert SQL statement tries to insert a time-stamp value to a field with GetDate() TSQL function as date time value. Insert into table1 (field1, ... fieldDt) values ('value1', ... GetDate()); The reason to use GetDate() function is that the SQL server may be at a remove site, and the date time may be in a difference time zone. Therefore, GetDate() will always get a date from the server. As the function can be verified in SQL Management Studio, this is what I get: SELECT GetDate(), LEN(GetDate()); -- 2010-06-10 14:04:48.293 19 One thing I realize is that the length is not up to the milliseconds, i.e., 19 is actually for '2010-06-10 14:04:48'. Anyway, the issue I have right now is that after the insert, the fieldDt actually has a date time value up to minutes, for example, '2010-06-10 14:04:00'. I am not sure why. I don't have permission to update or change the table with a trigger to update the field. My question is that how I can use a INSERT T-SQL to add a new row with a date time value ( SQL server's local date time) with a precision up to milliseconds?

• Problem changing Java version using alternatives

  - by Brian Lewis

  I'm not quite sure how I got into this mess, but for some reason I'm not able to change the current version of Java using alternatives. I can run alternatives --config java and type my selection but when I echo the version number for either java or javac, it spits back out 1.5 every time (despite alternatives showing the current version is 1.6). The server I'm working with is running RHEL5, by the way. I have verified that the paths used in alternatives are pointing to the correct directories.

• What do I name this class whose sole purpose is to report failure?

  - by Blair Holloway

  In our system, we have a number of classes whose construction must happen asynchronously. We wrap the construction process in another class that derives from an IConstructor class: class IConstructor { public: virtual void Update() = 0; virtual Status GetStatus() = 0; virtual int GetLastError() = 0; }; There's an issue with the design of the current system - the functions that create the IConstructor-derived classes are often doing additional work which can also fail. At that point, instead of getting a constructor which can be queried for an error, a NULL pointer is returned. Restructuring the code to avoid this is possible, but time-consuming. In the meantime, I decided to create a constructor class which we create and return in case of error, instead of a NULL pointer: class FailedConstructor : public IConstructor public: virtual void Update() {} virtual Status GetStatus() { return STATUS_ERROR; } virtual int GetLastError() { return m_errorCode; } private: int m_errorCode; }; All of the above this the setup for a mundane question: what do I name the FailedConstructor class? In our current system, FailedConstructor would indicate "a class which constructs an instance of Failed", not "a class which represents a failed attempt to construct another class". I feel like it should be named for one of the design patterns, like Proxy or Adapter, but I'm not sure which.

• C# Multithreaded Domain Design

  - by Thijs Cramer

  Let's say i have a Domain Model that im trying to make compatible with multithreading. The prototype domain is a game domain that consists of Space, SpaceObject, and Location objects. A SpaceObject has the Move method and Asteroid and Ship extend this object with specific properties for the object (Ship has a name and Asteroid has a color) Let's say i want to make the Move method for each object run in a seperate thread. That would be stupid because with 10000 objects, i would have 10000 threads. What would be the best way to seperate the workload between cores/threads? I'm trying to learn the basics of concurrency, and building a small game to prototype a lot of concepts. What i've already done, is build a domain, and a threading model with a timer that launches events based on intervals. If the event occurs i want to update my entire model with the new locations of any SpaceObject. But i don't know how and when to launch new threads with workloads when the event occurs. Some people at work told me that u can't update your core domain multithreaded, because you have to synch everything. But in that case i can't run my game on a dual quadcore server, because it would only use 1 CPU for the hardest tasks. Anyone know what to do here?

  My current project uses some ListFragments to show rows of data. The rows get updated dynamically every some seconds. The amount of rows varies with every update and in every ListFragment. I would like to show the amount of rows to the user, and think that the perfect place for that would be next to the Fragment's title in the ViewPagerIndicator. I provided a sample image for better comprehension: Sadly I am pretty clueless how to achieve this. I tried the following: public class PagerAdapter extends FragmentPagerAdapter { private int numOne = 0; private int numTwo = 0; // ... @Override public CharSequence getPageTitle(int position) { switch (position) { case 0: return "List 1 (" + numOne + ")"; case 1: return "List 2 (" + numTwo + ")"; default: return ""; } public void setNumOne(int num) { this.numOne = num; } public void setNumTwo(int num) { this.numTwo = num; } } When I now call the setNumXXX() method, nothing happens, until I move between fragments, what seems to trigger the getPageTitle() to fire. My question is: How can I force an update of the title(s), everytime when the num value changes?

• CakePHP: Custom Function in bootstrap that uses $ajax->link not working

  - by nekko

  Hello I have two questions: (1) Is it best practice to create global custom functions in the bootstrap file? Is there a better place to store them? (2) I am unable use the following line of code in my custom function located in my bootstrap.php file: $url = $ajax->link ( 'Delete', array ('controller' => 'events', 'action' => 'delete', 22 ), array ('update' => 'event' ), 'Do you want to delete this event?' ); echo $url; I receive the following error: Notice (8): Undefined variable: ajax [APP\config\bootstrap.php, line 271] Code } function testAjax () { $url = $ajax->link ( 'Delete', array ('controller' => 'events', 'action' => 'delete', 22 ), array ('update' => 'event' ), 'Do you want to delete this event?' ); testAjax - APP\config\bootstrap.php, line 271 include - APP\views\event\queue.ctp, line 19 View::_render() - CORE\cake\libs\view\view.php, line 649 View::render() - CORE\cake\libs\view\view.php, line 372 Controller::render() - CORE\cake\libs\controller\controller.php, line 766 Dispatcher::_invoke() - CORE\cake\dispatcher.php, line 211 Dispatcher::dispatch() - CORE\cake\dispatcher.php, line 181 [main] - APP\webroot\index.php, line 91 However it works as intended if I place that same code in my view: <a onclick=" event.returnValue = false; return false;" id="link1656170149" href="/shout/events/delete/22">Delete</a> Please help :) Thanks in advance!!

• Prevent "hg status" from showing everything under untracked directories

  - by Wei Hu

  I find the output of hg status too verbose for untracked directories. Suppose I have an empty repository that's managed by both git and hg. So there would be two directories, .git and .hg. The output of git status is: # Untracked files: # (use "git add <file>..." to include in what will be committed) # # .hg/ The output of hg status is: ? .git/HEAD ? .git/config ? .git/description ? .git/hooks/applypatch-msg.sample ? .git/hooks/commit-msg.sample ? .git/hooks/post-commit.sample ? .git/hooks/post-receive.sample ? .git/hooks/post-update.sample ? .git/hooks/pre-applypatch.sample ? .git/hooks/pre-commit.sample ? .git/hooks/pre-rebase.sample ? .git/hooks/prepare-commit-msg.sample ? .git/hooks/update.sample ? .git/info/exclude Is there a way to reduce its output to something like the following line? ? .git/

• Setting ModerationInformation.Status from Approved back to pending removes

  - by Gavin Morgan

  Seeing if anyone else has had this problem and a resolution to it. I have a visual studio sequential workflow on a list (not a library) which does NOT use tasks, the approval process is done through the Approve/Reject OOTB buttons on the list item. The approval is a 2 stage approval, whereby if the 1st stage is completed (via clicking the Approve OOTB button), i reset the ModerationInformation.Status from Approved back to pending then send an email to the 2nd stage approver. My problem is, when i set the the ModerationInformation.Status back to Pending from Approved so there is never an approved version, the Creator loses permissions to view the item, and i get the "cannot find item" error from SharePoint for the person who created the item. The 1st and 2nd level approvers and anyone with approve rights CAN still see the item. Some more background information. the code i am using to update the moderationinformation is I get the properties from the workflow event and get a hook into the listitem properties.Item.ModerationInformation.Status = SPModerationStatusType.Pending; properties.Item.Update(); can anyone help.
