• Mocking attributes - C#

  - by bob

  I use custom Attributes in a project and I would like to integrate them in my unit-tests. Now I use Rhino Mocks to create my mocks but I don't see a way to add my attributes (and there parameters) to them. Did I miss something, or is it not possible? Other mocking framework? Or do I have to create dummy implementations with my attributes? example: I have an interface in a plugin-architecture (IPlugin) and there is an attribute to add meta info to a property. Then I look for properties with this attribute in the plugin implementation for extra processing (storing its value, mark as gui read-only...) Now when I create a mock can I add easily an attribute to a property or the object instance itself? EDIT: I found a post with the same question - link. The answer there is not 100% and it is Java... EDIT 2: It can be done... searched some more (on SO) and found 2 related questions (+ answers) here and here Now, is this already implemented in one or another mocking framework?

  I have read this. http://stackoverflow.com/questions/2048485/jquery-checkbox <input type="checkbox" name="checkGroup" id="all"> <input type="checkbox" name="checkGroup" id="one" value="1"> <input type="checkbox" name="checkGroup" id="two" value="2"> <input type="checkbox" name="checkGroup" id="three" value="3"> <input type="hidden" name="storeCheck" value=""> $(function(){ $("#all").click(function(){ $("input:checkbox[name='checkGroup']").attr("checked",$(this).attr("checked")); }); $("input:checkbox[name='checkGroup']:not('#all')").click ( function(){ var totalCheckboxes = $("input:checkbox[name='checkGroup']:not('#all')").length; var checkedCheckboxes = $("input:checkbox[name='checkGroup']:not('#all'):checked").length; if ( totalCheckboxes === checkedCheckboxes ) { $("#all").attr("checked" , true ); } else { $("#all").attr("checked" , false ); } }); }); Demo I am trying to get the value of the checkboxs are checked as an array. for example if I checked All Get value array_check = 1,2,3 and passed this array to hidden name="storeCheck" otherwise: Get value of array_check( checkboxs checked ).and passed this array to hidden name="storeCheck"

• Bored with CS. What can I study that will make an impact?

  - by Eric Martinez

  So I'm going to an average university, majoring in CS. I haven't learned a damn thing and am in my third year. I've come to be really bored with studying CS. Initially, I was kind of misinformed and thought majoring in CS would make me a good "product creator". I make my money combining programming and business/marketing. But I have always done programming for the love of the art. I find things like algorithms interesting and want to be able to use CS to solve real world problems. I like the idea of bioinformatics and other hybrid studies. I'm not good enough, yet I hope, to really make a significant effort in those areas but I aspire to be. What are some other fields, open problems, and otherwise cool stuff to apply CS knowledge to in the real world? I'm really looking for something that will motivate me and re-excite me to continue studying CS. Edit: Like someone mentioned below. I am very interesting in the idea of being able to use computer science to help answer fundamental questions of life and the universe. But I'm not sure what is possible or how to begin.

• jquery filter .not()

  - by FFish

  I have a form with image thumbnails to select with checkboxes for downloading. I want an array with the images in jQuery for an Ajax call. 2 questions: - On the top of the table there is a checkbox to toggle all checkboxes that I want to exclude from the mapping. I had a look at jQuery's .not() but I can't implement it with the :checkbox selector - is the following example code correct? $(document).ready(function() { $('#myform').submit(function() { var images = $("input:checkbox", this).map(function() { return $(this).attr("name"); }).get().join(); alert(products); // outputs: ",check1,check2,check3" return false; // cancel submit action by returning false }); }); // end doc ready HTML: <form id="myform" action="" > <input type="checkbox" id="toggleCheck" onclick="toggleSelectAll()" checked="checked" ><br /> <input type="checkbox" name="001.jpg" checked="checked" /><br /> <input type="checkbox" name="002.jpg" checked="checked" /><br /> <input type="checkbox" name="003.jpg" checked="checked" /><br /> <br /> <input type="submit" value="download" > </form>

• Create a dynamic project template in VS 2010?

  - by jonhobbs

  This might sound a bit of an odd question but I know what I want to achieve, just don't know if it's possible. Firstly, I'd like to be able to create a visual studio project that the 2 developers that work with me can use as a basis for all new websites. I want to drop all the common files that we use in there, like jQuery, CMS files etc. so that every time they start a new project they don't have to worry about all of that stuff. I guess to do this I just set up a project and "File Export Template" ? Now, here's the tricky bit... When you open up one of the default templates in VS it asks you a few questions, such as if you want to use a master page or if you want to use code behind etc. What I would like to do is set up something similar so that when you use the project template it asks you what version of jQuery you want to use so that it can import the right file, or for example it might ask you if you want to include certain user controls that the CMS contains. If you tick the box then the folder with the necessary user controls would be put in your new project for you. I know MS can do this but can a user like me include functionality like that in my own project template? Hope that makes sense.

• Find all cycles in graph, redux

  - by Shadow

  Hi, I know there are a quite some answers existing on this question. However, I found none of them really bringing it to the point. Some argue that a cycle is (almost) the same as a strongly connected components (s. http://stackoverflow.com/questions/546655/finding-all-cycles-in-graph/549402#549402) , so one could use algorithms designed for that goal. Some argue that finding a cycle can be done via DFS and checking for back-edges (s. boost graph documentation on file dependencies). I now would like to have some suggestions on whether all cycles in a graph can be detected via DFS and checking for back-edges? My opinion is that it indeed could work that way as DFS-VISIT (s. pseudocode of DFS) freshly enters each node that was not yet visited. In that sense, each vertex exhibits a potential start of a cycle. Additionally, as DFS visits each edge once, each edge leading to the starting point of a cycle is also covered. Thus, by using DFS and back-edge checking it should indeed be possible to detect all cycles in a graph. Note that, if cycles with different numbers of participant nodes exist (e.g. triangles, rectangles etc.), additional work has to be done to discriminate the acutal "shape" of each cycle.

• encodeURIComponent is really useful?

  - by Marco Demaio

  Something I still don't understand when perfoming an http-get request to the server is what the advantage is in using JS fucntion encodeURIcomponent to encode each component of the http-get. Doing some tests I saw the server (using PHP) gets the values of the http-get request properly also if I don't use encodeURIcomponent!!! Obviuosly I still need to encode at client level the special character & ? = / : otherwise an http-get value like this "peace&love=virtue" would be considered as new key value pair of the http-get request instead of a one single value. But why does encodeURIcompenent encodes also many other charcaters like 'è' for example wich is translated into %C3%A8 that must be decoded on a PHP server using the utf8_decode function. By using encodeURIcomponent all values of the http-get request are utf8 encoded, therefor when getting them in PHP I have to call each time the utf8_decode function on each $_GET value which is quite annoying. Why can't we just encode only the & ? = / : charcaters??? see also: http://stackoverflow.com/questions/2607946/js-encodeuricomponent-result-different-from-the-one-created-by-form It shows that encodeURIComponent does not even encode properly because a simple browser FORM GET encodes charactrs like '€', in different way. So I still wonder what does this encodeURIComponent is for?

• Why is MySQL with InnoDB doing a table scan when key exists and choosing to examine 70 times more ro

  - by andysk

  Hello, I'm troubleshooting a query performance problem. Here's an expected query plan from explain: mysql> explain select * from table1 where tdcol between '2010-04-13:00:00' and '2010-04-14 03:16'; +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | 1 | SIMPLE | table1 | range | tdcol | tdcol | 8 | NULL | 5437848 | Using where | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ 1 row in set (0.00 sec) That makes sense, since the index named tdcol (KEY tdcol (tdcol)) is used, and about 5M rows should be selected from this query. However, if I query for just one more minute of data, we get this query plan: mysql> explain select * from table1 where tdcol between '2010-04-13 00:00' and '2010-04-14 03:17'; +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | 1 | SIMPLE | table1 | ALL | tdcol | NULL | NULL | NULL | 381601300 | Using where | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ 1 row in set (0.00 sec) The optimizer believes that the scan will be better, but it's over 70x more rows to examine, so I have a hard time believing that the table scan is better. Also, the 'USE KEY tdcol' syntax does not change the query plan. Thanks in advance for any help, and I'm more than happy to provide more info/answer questions.

• Perl: Process Communcation

  - by Shiftbit

  Can anyone explain how I can successfully get my process communicating. I find the perldoc on IPC confusing. What I have so far is: $| = 1; $SIG{CHLD} = {wait}; my $parentPid = $$; if ($pid = fork();) ) { if ($pid == 0) { pipe($parentPid, $$); open PARENT, "<$parentPid"; while (<PARENT>) { print $_; } close PARENT; exit(); } else { pipe($parentPid, $pid); open CHILD, ">$pid"; or error("\nError opening: childPid\nRef: $!\n"); open (FH, "<list") or error("\nError opening: list\nRef: $!\n"); while(<FH>) { print CHILD, $_; } close FH or error("\nError closing: list\nRef: $!\n"); close CHILD or error("\nError closing: childPid\nRef: $!\n); } else { error("\nError forking\nRef: $!\n"); } First Question is what does Perldoc pipe mean by READHANDLE, WRITEHANDLE? Second Questions is can I implement a solution without relying on CPAN or other modules?

• Parsing multibyte string in PHP

  - by Petr Peller

  I would like to write a (HTML) parser based on state machine but I have doubts how to acctually read/use an input. I decided to load the whole input into one string and then work with it as with an array and hold its index as current parsing position. There would be no problems with single-byte encoding, but in multi-byte encoding each value does not represent a character, but a byte of a character. Example: $mb_string = 'žšcr'; //4 multi-byte characters in UTF-8 for($i=0; $i < 4; $i++) { echo $mb_string[$i], PHP_EOL; } Outputs: L ž L A This means I cannot iterate through the string in a loop to check single characters, because I never know if I am in the middle of an character or not. So the questions are: How do I multi-byte safe read a single character from a string in a performance friendly way? Is it good idea to work with the string as it was an array in this case? How would you read the input?

• How do I add IIS Virtual Directories and arbitrary files in TFS Solution

  - by chriscena

  We have a web portal product from which we customize portals from customers. We use the precompiled web app and create a virtual directory (vd) where the customization resides. In addition to this we do some changes web.config in the web app folder. We would obviously like to keep these customizations under TFS source control. When I try to add the precompiled web app (which I don't want to add to source control), a warning tells me that the vds cannot be added. If I only add the folder that is referenced to by the vd, I lose the references to assemblies in the precompiled web app. My questions are: How do I structure a solution for adding IIS (sub application level) virtual directories and still retain the references to assemblies? Is it possible to add other directories/files from the web application level (like App_Theme, web.config etc.) to the solution? Since we already use Visual Source Safe, we have established a tree structure for each customization project: Project Root | |-Custom Sql | |-Custom Portal Files (which is added as a virtual directory) | |-Other Customizations I could probably do a lot of this manually through the source control explorer, but I'd like to have everything done through a solution. I've followed the instructions using this article: http://msdn.microsoft.com/en-us/library/bb668986.aspx, but this doesn't address the exact problem that I have. Oh, and we are currently using Visual Source Safe for portal customizaton, but are eager to make the move to TFS. TIA

• Is jQuery always the answer?

  - by Kibbee

  I've come across a couple questions, such as this one, and I really have to wonder why "Use jQuery" seems to be the answer when somebody asks how to do something in JavaScript. I understand that jQuery can save you a lot of time, and can help you out a lot, especially when you are doing a lot of fancy JavaScript in your site. However, in instances like this, and in many other instances, it seems like it's just jumping around the problem instead of answering the question. I also feel like this builds too much dependency into libraries. I've seen way too many developers that simply rely too much on libraries, and if they encounter a situation where they didn't have the library, they would be completely unable to function. I feel like there are already enough developers who don't know JavaScript, without just telling everybody to not learn JavaScript, and use jQuery. So, just to reiterate the question. Do you think there's too much of a tendency to use jQuery, for small pieces of JavaScript, when most of the functionality of jQuery isn't being used. Should developers be fluent in the use of bare JavaScript so they don't get too dependent on using libraries? [Additional related conversation topic] Does the existence of jQuery give too much slack to web browser developers who write the JavaScript engines? If we just have workarounds to cover all the inconsistencies in JavaScript, what pressure is there on browser makers to ensure that their JavaScript library works as it should. I feel like this extrapolates the same problem discussed in SO Podcast #36 of "be conservative in what you send, liberal in what you accept". By being so liberal with bad JavaScript engines, and using a common library to work around the flaws, we are promoting their use, and extending the problem.

• Scala programming language for beginners, is it a legend?

  - by ali

  Hi every one, I am Ali from Saudi Arabia. undoubtedly, Scala is one of the best programming language for any programmer to learn, but there is "good" problems that is faced especially by beginners, and what seems frustrating that these problems won't solve soon, so as a beginner and on behalf of beginners let me raise these "objective" questions: 1- why scala has no effective and stable development platform, in fact, it suffers many problems with Eclipse, Netbeat, and Intellij. 2- although I have looked for a clear,easy, and understandable explanation of how to get started with Scala, but fortunately, there was no article or guide that deserves to spend the time I have spent to read it. nobody could tell you clear steps that fit you as a beginner who wants to start his"HELLO WORLD" with Scala, while all other languages have its "HELLO WORLD" guides and books. thank you for your time, be sure that you read notes below. 1- I have no experience in programming language before. 2- don't tell me "not to begin with scala", simply, because I will do. 3- OS is windows vista home premium. 4- I hate excuses, such as Scala is new language......etc

• Are AJAX sites crawlable by search engines?

  - by frankadelic

  I had always assumed that AJAX-driven content was invisible to search engines. (i.e. content inserted into the DOM via XMLHTTPRequest) For example, in this site, the main content is loaded via AJAX request by the browser: http://www.trustedsource.org/query/terra.cl ...if you view this page with Javascript disabled, the main content area is blank. However, Google cache shows the full content after the AJAX load: http://74.125.155.132/search?q=cache:JqcT6EVDHBoJ:www.trustedsource.org/query/terra.cl+http://www.trustedsource.org/query/terra.cl&cd=1&hl=en&ct=clnk&gl=us So, apparently search engines do index content loaded by AJAX. Questions: Is this a new feature in search engines? Most postings on the web indicate that you have to publish duplicate static HTML content for search engines to find them. Are there any tricks to get an AJAX-driven content to be crawled by search engines (besides creating duplicate static HTML content). Will the AJAX-driven content be indexed if it is loaded from a separate subdomain? How about a separate domain?

• Make browser to go back by reloading page 1st and then scrolling it back again too

  - by Marco Demaio

  EXPLAINING WHAT I'M TRYING TO SOLVE: I have a webpage (file_list.php) showing a list of files, and next to each file there is a button to delete it. When user press the DELETE button close to a certain file name, the browser goes to a script called delete_file.php that deletes the file and then it tells browser to go back to the file_list.php delete_file.php uses a simple header("Location: file_list.php”); to go back to file_list.php When browser goes back to file_list.php it reloads the page, but it DOES NOT scroll it back again to where the user was before. So let's say the user scrolled the files list and deleted the last file, when the browser shows again the page file_list.php it won't be scrolled to the bottom of the page again. THE WORKAROUND I CAME OUT WITH: I found a strange way to work around this, basically instead of using header("Location: file_list.php”); in delete_file.php I simply use a javascript call window.history.go(-1). This workaround works perfectly when user is in session (simply using PHP session_start function): the browser RELOADS the file_list.php page and then scrolls it also bask to where it was before. But if the user is NOT in session the browser scrolls the page but IT DOES NOT RELOAD IT before, so the user would still see the file he deleted in the file list. THE QUESTIONS Do you know how to reproduce the behavior of the browser when goes back being in session even if we are not in session? Do you know a way out of this, even another way of solving this matter? Thanks! *I know I could use AJAX to delete the file so I would not have to go every time to delete_file.php, but this is not the answer*.

• Forwarding first responder to UIScrollView unsuccessful

  - by Winston

  Hello, I am trying to create an image cropping bpx whereby the underlying image can be zoomed an scrolled while the cropping "maskview" layer stays the same and the corners can be dragged in any direction. To achieve this, the ImageView is added to a UIScrollView, and this is added to the SelectionViewController.view . I then add the cropping "maskview" layer to the SelectionViewController.view. I did this instead of adding to the scrollview so that the cropping maskview won't be expanded when the underlying image expands. @interface SelectionViewController : UIViewController <UIScrollViewDelegate> { UIImageView *photoview; // Added to self.scrollview MaskedView *maskedview; // Added to self.view UIScrollView *scrollview; // Added to self.view } The maskview has first responder status and responds accordingly. However, the only event I am interested in the maskview is if any of the corners are dragged (this works fine). The problem I want to try to solve is two-fold: If it is a pinch or zoom gesture, I am trying to forward the responder to the UIScrollview using: [self.nextResponder touchesMoved:touches withEvent:event]; The scrollview does not seem to respond. I have confirmed that the self.nextResponder after the maskedview is the SelectionViewController's view itself. From there, it doesn't seem like the UIScrollview responds. It does respond fine if I remove the cropping maskedview. If I zoom in on the underlying image and the cropping maskview rectangle is still the same, I want to now crop the actual zoomed image. Let's say for the upper left hand corner of the crop box, how can I find what the coordinates translates to in the underlying UIImageView now that the image has been zoomed? Any insight into either of these questions would be appreciated. Thank you, Winston

• What is the best way to handle autorotation with multiple subview?

  - by thangnguyen

  I am learning and programing an application. I do this project based on what I learned from the book Beginning iphone 3 development. I have two main questions here: I would like to create a multi utility application so I need multiple-view. I have a main view controller which will control switching between views. In this example I have two views A and B. I have 2 view controller A and B which will handles all of events on these 2 views. I have 2 nib files viewA.xib and viewB.xib. One of the uitility is reading PDF. So I create another class which handle the PDF file which can load a PDF page call PDFview. From Interface Builder, I selected class identity for view of the viewB.xib as PDFView class. The result is I can switching between View A and view B. View B will display the content of the PDF page. I am not sure if my solution is right or wrong but now I don't know how to handle the autorotation. The rotation will active the view controller B. But the PDFView handle how to display the PDF on the View. Could you please tell me how I should handle this in a right way? Second question: Should I create the subview automatically? In case I need to do the swipe page animation, how can I do that? I think that I need to load another subview so I can do the animation when swap view. But I think this solution will waste the resource. I can just load another page of the PDF, but in this case I don't know how to use animation? Please tell me how I should solve this? I highly appreciate your time reading and answering my question. Thang Nguyen

• c# CF Restart a thread

  - by Ed

  Hi all, Supose you have a form with a button that starts/stops a thread (NOT pausing or interrupting, I really need to stop the thread !) Check out this code: Constructor() { m_TestThread = new Thread(new ThreadStart(ButtonsThread)); m_bStopThread = false; } ButtonClick { // If the thread is not running, start it m_TestThread.Start(); // If the thread is running, stop it m_bStopThread = true; m_TestThread.Join(); } ThreadFunction() { while(!m_bStopThread) { // Do work } } 2 questions (remember CF): - How can I know if the thread is running (I cannot seem to access the m_pThreadState, and I've tried the C++ GetThreadExitCode(), it give false results) ? - Most important question : if I have stopped the thread, I cannot restart it, most probably because the m_TestThread.m_fStarted is still set (and it is private so I cannot access it) ! And thus m_TestThread.Start() generates an exception (StateException). Stopping the thread with an Abort() doesn't solve it. If I put my m_TestThread = null; it works, but then I create a memory leak. The GC doesn't clean up either, even if I wait for xx seconds. Anybody has an idea ? All help highly appreciated ! Grtz E

• Card emulation via software NFC

  - by user85030

  After reading a lot of questions, i decided to post this one. I read that stock version of android does not support API's for card emulation. Also, we cannot write custom applications to secure element embedded in nfc controllers due to keys managed by google/samsung. I need to emulate a card (mifare or desfire etc). The option i can see is doing it via software. I have a ACR122U reader and i've tested that NFC P2P mode works fine with the Nexus-S that i have. 1) I came across a site that said that nexus s's NFC controller (pn532) can emulate a mifare 4k card. If this is true, can i write/read apdu commands to this emulated card? (Probably if i use a modded rom like cyanogenmod) 2) Can i write a android application that reads apdu commands sent from the reader and generate appropriate responses (if not fully, then upto some extent only). To do so, i searched that we need to patch nexus s with cynagenmod. Has someone tried emulating card via this method? I see that this is possible since we have products from access control companies offering mobile applications via which one can open doors e.g. http://www.assaabloy.com/en/com/Products/seos-mobile-access/

• Show cue banner for wpf ComboBox with grouping

  - by Adam Duston

  I have a ComboBox in my WPF form: <ComboBox Margin="75,0,15,102" Name="videoFormatCombo" Height="23" VerticalAlignment="Bottom" DataContext="{StaticResource GroupedVideoFormats}" ItemsSource="{Binding}" ItemTemplate="{StaticResource VideoFormatTemplate}"> <ComboBox.GroupStyle> <GroupStyle HeaderTemplate="{StaticResource GroupHeader}"/> </ComboBox.GroupStyle> </ComboBox> As you might be able to guess, GroupedVideoFormats is a CollectionViewSource with grouping. I need to get a cue banner to display for this ComboBox. I've attempted the solution that is (very verbosely) outlined in this blog post, but it will not work for a ComboBox with grouped data. The two solutions outlined in superfluousprefixhttp://stackoverflow.com/questions/2548757/how-can-the-blank-space-in-a-c-combobox-be-filled-as-a-hint-for-the-user are for Windows Forms ComboBoxes only, and won't work with WPF. If it would help to see all the original source, this particular form is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/blob/master/MSWindows/Windows/FileSelect.xaml . It's an open-source project, so the entire project is on github: superfluousprefixhttp://github.com/8planes/mirovideoconverter/tree/master/MSWindows . Thank you for any advice! Adam P.S. stackoverflow wouldn't let me make more than one anchor tag in my post, hence the long urls with the superfluous prefix. Sorry!

• Absolute positioned div jumps outside containing div in IE7

  - by user367232

  Having trouble with a couple of display issues in IE7. Firstly, my large text headers display too far up in Internet Explorer (all pages) Secondly, my descriptions on my Portfolio pages end up outside their containing divs. Works great on FF/Chrome/Opera/Safari though! You'll see what I mean: http://bit.ly/a3hUD4 (I've used bitly so my dumb questions don't show up when someone googles my website). I've googled extensively. Not sure if problem number 2 is a overflow issue, or a absolute positioning bug in IE. Here's the CSS for the centre div with the jumbo-text titles .column1 { padding: 103px 10px 10px 10px; float: left; width: 500px; margin: 0; } And for the description div on the portfolio page .porttxtbox { text-align: right; background-image: url(images/porttxtBG.png); bottom: 0; position: absolute; width: 100%; padding: 0px; margin: 0px; } And it's container div .portimgbox { padding: 0px; margin: 0px; height: 250px; width: 480px; position: relative; border: 5px solid #EAEAEA; Thanks in advance!

• iPhone 4.0 on iPhone but still Ad-Hoc compile for 3.1.3?

  - by Mark

  Device: Version : 3.1 Build: 3511 Device: iPhone OS: iPhone OS 4.0 xCode 3.2.2 (Old) xCode 3.2.3 (New; For iPhone 4.0 Beta) Background: As you can see I installed 4.0 on my iPhone as I read on this forum it's really hard to near impossible to downgrade back to 3.1.3, but it's my only device I have and use for development. When I try to continue to develop and build with the old xCode it tells me that "No provisioned iPhone OS device is connected". When I select Simulator it does compile and build, however when I spread this file it does not work on the devices of my testers, they get a Signed error. When I run the new xCode, it does compile and build on the Device and when I spread this file, it does work on the devices of my testers (which are running the current official version 3.1.3). Questions: Why is there a difference between building for Simulator and Device? A simulator build never seem to work on the devices of my testers because of signing issues and the build for device does work. Currently it seems the old xCode became useless, however I read that you may not use the Beta xCode to build your application for release. So knowing the above how am I able to pull this off with my current setup due the fact the old xCode won't let me build properly.

• How do I add a header with data to a QTableWidget in Qt?

  - by San Jacinto

  Hi, I'm still learning Qt and I am indebted to the SO community for providing me with great, very timely answers to my Qt questions. Thank you. I'm quite confused on the idea of adding a header to a QTableWidget. What I'd like to do is have a table that contains information about team members. Each row for a member should contain his first and last name, each in its own cell, an email address in one cell, and office in the other cell. I'd to have a header above these columns to name them as appropriate. I'm trying to start off easy and get just the header to display "Last" (as in last name). Here is my code. int column = m_ui-teamTableWidget-columnCount(); m_ui-teamTableWidget-setColumnCount(column+1); QString* qq = new QString("Last"); m_ui-teamTableWidget-horizontalHeader()-model()-setHeaderData(0, Qt::Horizontal, QVariant(QVariant::String, &qq)); My table gets rendered corretly, but the header doesn't contain what I would expect. It contains 1 cell that contains the text "1". I am obviously doing something very silly here that is wrong, but i am lost. I keep pouring over the documentation, finding nothing. Here are the documentation links to the function calls I am making for the very last line. http://doc.trolltech.com/4.5/qtableview.html#horizontalHeader http://doc.trolltech.com/4.5/qabstractitemview.html#model http://doc.trolltech.com/4.5/qabstractitemmodel.html#setHeaderData Thanks for any and all help. Edit: HOW I SOLVED THE PROBLEM Using some help from the accepted answer, I came up with the following code: m_ui-teamTableWidget-setColumnCount(m_ui-teamTableWidget-columnCount()+1); QTableWidgetItem* qtwi = new QTableWidgetItem(QString("Last"),QTableWidgetItem::Type); m_ui-teamTableWidget-setHorizontalHeaderItem(0,qtwi);

• Setting up ehcache replication - what multicast settings do I need?

  - by Darren Greaves

  I am trying to set up ehcache replication as documented here: http://ehcache.sourceforge.net/EhcacheUserGuide.html#id.s22.2 This is on a Windows machine but will ultimately run on Solaris in production. The instructions say to set up a provider as follows: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=4446, timeToLive=32"/> And a listener like this: <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" properties="hostName=localhost, port=40001, socketTimeoutMillis=2000"/> My questions are: Are the multicast IP address and port arbitrary (I know the address has to live within a specific range but do they have to be specific numbers)? Do they need to be set up in some way by our system administrator (I am on an office network)? I want to test it locally so am running two separate tomcat instances with the above config. What do I need to change in each one? I know both the listeners can't listen on the same port - but what about the provider? Also, are the listener ports arbitrary too? I've tried setting it up as above but in my testing the caches don't appear to be replicated - the value added in one tomcat's cache is not present in the other cache. Is there anything I can do to debug this situation (other than packet sniffing)? Thanks in advance for any help, been tearing my hair out over this one!

• How to select a rectangle from List<Rectangle[]> with Linq

  - by dboarman

  I have a list of DrawObject[]. Each DrawObject has a Rectangle property. Here is my event: List<Canvas.DrawObject[]> matrix; void Control_MouseMove ( object sender, MouseEventArgs e ) { IEnumerable<Canvas.DrawObject> tile = Enumerable.Range( 0, matrix.Capacity - 1) .Where(row => Enumerable.Range(0, matrix[row].Length -1) .Where(column => this[column, row].Rectangle.Contains(e.Location))) .????; } I am not sure exactly what my final select command should be in place of the "????". Also, I was getting an error: cannot convert IEnumerable to bool. I've read several questions about performing a linq query on a list of arrays, but I can't quite get what is going wrong with this. Any help? Edit Apologies for not being clear in my intentions with the implementation. I intend to select the DrawObject that currently contains the mouse location.
