• sIFR multiple calls don't work :(

  - by roxane

  Hello ! I'm trying to use sIFR on my menu and on my headers... but only one call works... the others that I put after never appear :(... Can somebody help me ? Note : I'm using the r436 and below is my code ... var segoe = { src: 'pathto/segoe.swf', ratios: [7, 1.58, 8, 1.49, 10, 1.5, 11, 1.45, 16, 1.46, 21, 1.44, 22, 1.41, 27, 1.42, 30, 1.41, 32, 1.4, 35, 1.41, 36, 1.4, 38, 1.39, 41, 1.4, 58, 1.39, 65, 1.38, 66, 1.39, 102, 1.38, 104, 1.37, 106, 1.38, 107, 1.37, 108, 1.38, 109, 1.37, 110, 1.38, 112, 1.37, 114, 1.38, 120, 1.37, 121, 1.38, 1.37] }; sIFR.activate(segoe); sIFR.replace(segoe, { selector: '#header ul li a span.title', css: ['.sIFR-root { text-align: center; font-size:13px; letter-spacing:2; font-weight: bold; text-transform:uppercase; cursor: pointer; color:#FFFFFF; background-color:#0C2C39; margin:0 3px; }'], wmode: 'transparent' }); sIFR.replace(segoe, { selector: 'h1', css: ['.sIFR-root { text-align: center; font-size:13px; letter-spacing:2; font-weight: bold; text-transform:uppercase; cursor: pointer; color:#000; background-color:#fff; margin:0 3px; }'] });

• Is there command-line tool to extract typedef, structure, enumeration, variable, function from a C or C++ file?

  - by FooF

  I am desiring a command-line tool to extract a definition or declaration (typedef, structure, enumeration, variable, or function) from a C or C++ source file. Also a way to replace an existing definition/declaration would be handy (after transforming the extracted definition by a user-submitted script). Is there such generic tool available, or is some resonably close approximation of such a tool? Scriptability and ability to hook-up with user created scripts or programs is of importance here, although I am academically curious of GUI programs too. Open source solutions for Unix/Linux camp are preferred (although I am curious of Windows and OS X tools too). Primary language interests are C and C++ but more generic solution would be even better (I think we do not need super accurate parsing capabilities for finding, extracting and replacing a definition in a program source file). Sample Use Cases (extra - for the curious mind): Given deeply nested structs and variable (array) initializations of these types, suppose there is a need to change a struct definition by adding or reordering fields or rewriting the variable/array definitions in more readable format without introducing errors resulting from manual labor. This would work by extracting the old initializations, then using a script/program to write the new initializations to replace the old ones. For implementing a code browsing tool - extract a definition. Decorative code generation (e.g. logging function entries / returns). Scripted code structuring (e.g. extract this and that thing and put in different place without change - version control commit comment could document the command to perform this operation to make it evident and verifiable that nothing changed). Note about tags: More accurate tag than code-generation would be code-transformation but it does not exist.

• How to use the values from session variables in jsp pages that got saved using @Scope("session") in the mvc controllers

  - by droidsites

  Doing a web site using spring mvc. I added a SignupController to handle all the sign up related requests. Once user signup I am adding that to a session using @Scope("session"). Below is the SignupController code, SignupController.java @Controller @Scope("session") public class SignupController { @Autowired SignupServiceInter signUpService; private static final Logger logger = Logger.getLogger(SignupController.class); private String sessionUser; @RequestMapping("/SignupService") public ModelAndView signUp(@RequestParam("userid") String userId, @RequestParam("password") String password,@RequestParam("mailid") String emailId){ logger.debug(" userId:"+userId+"::Password::"+password+"::"); String signupResult; try { signUpService.registerUser(userId, password,emailId); sessionUser = userId; //adding the sign up user to the session return new ModelAndView("userHomePage","loginResult","Success"); //Navigate to user Home page if everything goes right } catch (UserExistsException e) { signupResult = e.toString(); return new ModelAndView("signUp","loginResult", signupResult); //Navigate to signUp page back if user does not exist } } } I am using "sessionUser" variable to store the signed up User Id. My understanding is that when I use @Scope("session") for the controller all the instance variables will added to HttpSession. So by that understanding I tried to access this "SessionUser" in userHomePage.jsp as, userHomepage.jsp Welcome to <%=session.getAttribute("sessionUser")%> But it throws null. So my question is how to use the values from session variables in jsp pages that got saved using @Scope("session") in the mvc controllers. Note: My work around is that pass that signed User Id to jsp page through ModelAndView, but it seems passing the value like these among the pages takes me back to managing state among pages using QueryStrings days.

• Is there a Java data structure that is effectively an ArrayList with double indicies and built-in in

  - by Bob Cross

  I am looking for a pre-built Java data structure with the following characteristics: It should look something like an ArrayList but should allow indexing via double-precision rather than integers. Note that this means that it's likely that you'll see indicies that don't line up with the original data points (i.e., asking for the value that corresponds to key "1.5"). As a consequence, the value returned will likely be interpolated. For example, if the key is 1.5, the value returned could be the average of the value at key 1.0 and the value at key 2.0. The keys will be sorted but the values are not ensured to be monotonically increasing. In fact, there's no assurance that the first derivative of the values will be continuous (making it a poor fit for certain types of splines). Freely available code only, please. For clarity, I know how to write such a thing. In fact, we already have an implementation of this and some related data structures in legacy code that I want to replace due to some performance and coding issues. What I'm trying to avoid is spending a lot of time rolling my own solution when there might already be such a thing in the JDK, Apache Commons or another standard library. Frankly, that's exactly the approach that got this legacy code into the situation that it's in right now.... Is there such a thing out there in a freely available library?

• What's a good way to format AJAX responses? Or, using Django templating with AJAX

  - by synic

  In some of the code I'm working on, the author max AJAX calls to a Django view that returns JSON. Once the JSON is retrieved, it'll be injected into the page with a function that looks like this (note, this is a simplification, but I'm sure you know what I'm getting at here): function build_event_listing(events) { var html = ''; for(int i = 0; i < events.length; i++) { event = events[i]; html += "<h2>" + event.title + "</h2>\n"; html += "<p>" + event.description + "</p>"; html += "Click <a href='/event/view/" + event.id + "'>here<a> for more info."; } events_div.html(html); } I really don't like this approach. To change the look of each event listing, the designer would have to modify that ugly JS. I'd much rather make use of Django's templating system, but I'm wondering how I can do this? I had the idea of writing the view like this: def view_listings(req): events = models.Event.objects.all() html = [] for event in events: html.append( render_to_string('event/single_event.html', { 'event': event, }, context_instance=RequestContext(req)) return HttpResponse(''.join(html), mimetype='text/html') ... but it just seems like there should be a better way. Any ideas?

• How do I manipulate the format on a DataGridView that is bound to a Data Source?

  - by Jack Johnstone

  I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the DateTime format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d) which is in string format. I´ve created an algorithm for the transformation between values (date to weekday), but can I populate the affected cells with yyww,d (string) instead of mm/dd/yyyy (DateTime)? This is what I´ve been testing out, without success (and note, it´s on the last line the problem becomes obvious, as the cell value won´t accept a string on runtime - it still wants to be a DateTime...) private void DataGridViewQueryFindRequests_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { string weekAndDay = ""; DataGridViewCell cell = DataGridViewQueryFindRequests.Rows[e.RowIndex].Cells[e.ColumnIndex]; if (cell.ColumnIndex == 13 && cell.Value == null) mEmptyRow = true; if ((cell.ColumnIndex == 14 || cell.ColumnIndex == 15) && !mEmptyRow) { weekAndDay = ClassWeeksAndDates.dateToWeekNumber(Convert.ToDateTime(cell.Value)); cell.ValueType = typeof(string); cell.Value = weekAndDay; } }

• std::map keys in C++

  - by Soumava

  I have a requirement to create two different maps in C++. The Key is of type CHAR * and the Value is a pointer to a struct. I am filling 2 maps with these pairs, in separate iterations. After creating both maps I need find all such instances in which the value of the string referenced by the CHAR * are same. For this i am using the following code : typedef struct _STRUCTTYPE { .. } STRUCTTYPE, *PSTRUCTTYPE; typedef pair {CHAR *,PSTRUCTTYPE} kvpair; .. CHAR *xyz; PSTRUCTTYPE abc; after filling the information; Map.insert (kvpair(xyz,abc)); the above is repeated x times for the first map, and y times for the second map. after both are filled out; std::map {CHAR *, PSTRUCTTYPE} :: iterator Iter,findIter; for (Iter=iteratedMap-begin();Iter!=iteratedMap-end();mapIterator++) { char *key = Iter-first; printf("%s\n",key); findIter=otherMap-find(key); //printf("%u",findIter-second); if (findIter!=otherMap-end()) { printf("Match!\n"); } } The above code does not show any match, although the list of keys in both maps show obvious matches. My understanding is that the equals operator for CHAR * just equates the memory address of the pointers. My question is, what should i do to alter the equals operator for this type of key or could I use a different datatype for the string? *note : {} has been used instead of angle brackets as the content inside angle brackets was not showing up in the post.

• C++ Vector of vectors is messing with me

  - by xbonez

  If I put this code in a .cpp file and run it, it runs just fine: #include <iostream> #include <vector> #include <string> using namespace std; typedef vector<int> row; typedef vector<row> myMatrix; void main() { //cout << endl << "test" << endl; myMatrix mat(2,2); mat[0][1] = 2; cout << endl << mat[0][1] << endl; } But, if I make a .h and a .cpp file with the .h file like this, it gives me boatloads of errors. #ifndef _grid_ #define _grid_ #include<iostream> #include<vector> #include<string> using namespace std; typedef vector<int> row; typedef vector<row> myMatrix; class grid { public: grid(); ~grid(); int getElement(unsigned int ri, unsigned int ci); bool setElement(unsigned int ri, unsigned int ci, unsigned int value); private: myMatrix sudoku_(9,9); }; #endif These are some of the errors I get: warning C4091: 'typedef ' : ignored on left of 'int' when no variable is declared error C4430: missing type specifier - int assumed.

• Calculating percent "x/y * 100" always results in 0?

  - by Patrick Beninga

  In my assignment i have to make a simple version of Craps, for some reason the percentage assignments always produce 0 even when both variables are non 0, here is the code. import java.util.Random; Header, note the variables public class Craps { private int die1, die2,myRoll ,myBet,point,myWins,myLosses; private double winPercent,lossPercent; private Random r = new Random(); Just rolls two dies and produces their some. public int roll(){ die1 = r.nextInt(6)+1; die2 = r.nextInt(6)+1; return(die1 + die2); } The Play method, this just loops through the game. public void play(){ myRoll = roll(); point = 0; if(myRoll == 2 ||myRoll == 3 || myRoll == 12){ System.out.println("You lose!"); myLosses++; }else if(myRoll == 7 || myRoll == 11){ System.out.println("You win!"); myWins++; }else{ point = myRoll; do { myRoll = roll(); }while(myRoll != 7 && myRoll != point); if(myRoll == point){ System.out.println("You win!"); myWins++; }else{ System.out.println("You lose!"); myLosses++; } } } This is where the bug is, this is the tester method. public void tester(int howMany){ int i = 0; while(i < howMany){ play(); i++; } bug is right here in these assignments statements winPercent = myWins/i * 100; lossPercent = myLosses/i* 100; System.out.println("program ran "+i+" times "+winPercent+"% wins "+ lossPercent+"% losses with "+myWins+" wins and "+myLosses+" losses"); } }

• Spring MVC - Set an actionURL parameter with Javascript

  - by jeffl8n

  Is it possible to dynamically set a Spring MVC portlet:actionURL portlet:param using javascript? I have tried with the following code, but the id value always comes across as null to the controller. I have verified that setting the portlet:param manually passes the value correctly: <portlet:param name="id" value="2" /> I have also verified the value in the javascript is being set correctly and is not null. (Note: I've changed the variable names, etc. from the original code to simplify it and obfuscate it since it is my employer's code.) JSP: <portlet:actionURL var="modifyURL"> <portlet:param name="do" value="modify" /> <portlet:param name="id" value="${model.id}" /> </portlet:actionURL> ... <form:form action="${modifyURL}" id="modifyForm" modelAttribute="model"> <form:hidden path="id" id="id" /> </form:form> Javascript called when the update URL is clicked: function update() { document.forms[0]["id"].value = selectedId; document.forms[0].submit(); } Controller: @RequestMapping(params = {"do=modify"}) public void modify(@ModelAttribute("model") Model model, @RequestParam(value = "id", required=true) Long id, ActionRequest request, ActionResponse response, SessionStatus sessionStatus, ModelMap modelMap) { ....

• Div's are not filtered as :hidden when display:none; is appended as style

  - by CodeMonkey

  Hey folks I have some simple HTML: <div id="selectorContainer"> <div id="chainedSelector" style="display: none;"><% Html.RenderPartial("ProjectSuggest/ChainedProjectSelector"); %></div> <div id="suggestSelector"><% Html.RenderPartial("ProjectSuggest/SuggestControl", new SuggestModeDTO{RegistrationMode = Model.RegistrationMode}); %></div> </div> which is two containers for controls. I have jQuery code to toggle between displaying these, but I need to store as a cookie which one was used last time the user was logged in (i.e. which one was visible). The storing of the cookie is not the problem. The problem is that I for some reason am not able to detect which one is the hidden one, using .is(":hidden"), and not able to detect which one is visible using .is(":visible") When I use those two selectors, I always get both. "true" and "true" for both, eventhough one has display: none; and the other doesn't. Please note that they are NOT placed inside a hidden container which otherwise would hide both, so there are not any hidden ancestor containers. Can anyone maybe explain why this could happen? jQuery code containing source for getting the Id's and for getting the selected one (which currently is broken): getChainedSelectorId: function() { return "#chainedSelector"; }, getSuggestSelectorId: function() { return "#suggestSelector"; }, getSelectedSelector: function() { alert($(this.getChainedSelectorId()).is(":hidden")); alert($(this.getSuggestSelectorId()).is(":hidden")); var selected = ($(this.getChainedSelectorId()).is(":visible") ? this.getChainedSelectorId() : this.getSuggestSelectorId()); alert(selected); return selected; }, Thanks in advance.

• casting char[][] to char** causes segfault?

  - by Earlz

  Ok my C is a bit rusty but I figured I'd make my next(small) project in C so I could polish back up on it and less than 20 lines in I already have a seg fault. This is my complete code: #define ROWS 4 #define COLS 4 char main_map[ROWS][COLS+1]={ "a.bb", "a.c.", "adc.", ".dc."}; void print_map(char** map){ int i; for(i=0;i<ROWS;i++){ puts(map[i]); //segfault here } } int main(){ print_map(main_map); //if I comment out this line it will work. puts(main_map[3]); return 0; } I am completely confused as to how this is causing a segfault. What is happening when casting from [][] to **!? That is the only warning I get. rushhour.c:23:3: warning: passing argument 1 of ‘print_map’ from incompatible pointer type rushhour.c:13:7: note: expected ‘char **’ but argument is of type ‘char (*)[5]’ Are [][] and ** really not compatible pointer types? They seem like they are just syntax to me.

• Windows service: Listening on socket while running as LocalSystem

  - by Socob

  I'm writing a small server-like program in C for Windows (using MinGW/GCC, testing on Windows 7) which is eventually supposed to run as a service with the LocalSystem account. I am creating a socket, and using Windows Sockets bind(), listen() and accept() to listen for incoming connections. If I run the application from the command line (i.e. not as a service, but as a normal user), I have no problems connecting to it from external IPs. However, if I run the program as a service with the LocalSystem account, I can only connect to the service from my own PC, either with 127.0.0.1 or my local address, 192.168.1.80 (I'm behind a router in a small local network). Neither external IPs nor other PCs in the same local network, using my local address, can connect now, even though there were no problems without running as a service. Now, I've heard that networking is handled differently or even not accessible (?) when running as LocalSystem or LocalService or that services cannot access both the desktop and the network (note: my service is not interactive) at the same time due to security considerations. Essentially, I need to find out what's going wrong/how to listen for connections in a service. Is running as NetworkService the same as running as LocalSystem, but with network access? Surely there must be servers that can run as background services, so how do they do it?

• Image not rendering in dompdf

  - by Venkat

  I am using codeIgniter and dompdf for my application for generating pdfs. The below code is the code which i am using to display an image. <div class=\"block_head\"> <h2>Image display</h2>"; $image_location = "/images/xxx.png"; $html .="<img src=\"".$image_location."\" width=\"200\" height=\"200\" /> </div>"; I tested and debugged all ways whether i am doing something wrong. Like this first i checked whether the path is wrong. This is path on the server. It's correct. I tested by echoing $html also it's showing perfectly path. When i clicked on that path image is displaying. But when i am trying to render it in pdf it's not displaying. Note: PDF is generating perfectly without image.

• How to set background color of tableView

  - by Praveen

  Hi Folks, I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller. My nib file structure is FileOwner View UITableView (Note: i set the TableView to groupedTable section) First attempt, I created the UIView in the code viewDidLoad UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease; [view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place [self.tableView sendSubViewToBack:view]; It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview. Second attempt, I created the imageView View ImageView UITableView and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work. I googled but did not the peaceful answer.

• Howto display or view encrypted data in encrypted form?

  - by Brian Gianforcaro

  In the Wikipedia Article on Block Cipher Modes they have a neat little diagram of an unencrypted image, the same image encrypted using ECB mode and another version of the same image encrypted using another method. At university I have developed my own implementation of DES (you can find it here) and we must demo our implementation in a presentation. I would like to display a similar example as shown above using our implementation. However most image files have header blocks associated with them, which when encrypting the file with our implementation, also get encrypted. So when you go to open them in an image viewer, they are assumed to be corrupted and can't be viewed. I was wondering if anybody new of a simple header-less image format which we could use to display these? Or if anyone had any idea's as to how the original creator of the images above achieved the above result? Any help would be appreciated, Thanks Note: I realise rolling your own cryptography library is stupid, and DES is considered broken, and ECB mode is very flawed for any useful cryptography, this was purely an academic exercise for school. So please, no lectures, I know the drill.

• Unknown reason for code executing the way it does in python

  - by Jasper

  Hi I am a beginner programmer, using python on Mac. I created a function as a part of a game which receives the player's input for the main character's name. The code is: import time def newGameStep2(): print ' ****************************************** ' print '\nStep2\t\t\t\tCharacter Name' print '\nChoose a name for your character. This cannot\n be changed during the game. Note that there\n are limitations upon the name.' print '\nLimitations:\n\tYou cannot use:\n\tCommander\n\tLieutenant\n\tMajor\n\t\tas these are reserved.\n All unusual capitalisations will be removed.\n There is a two-word-limit on names.' newStep2Choice = raw_input('>>>') newStep2Choice = newStep2Choice.lower() if 'commander' in newStep2Choice or 'lieutenant' in newStep2Choice or 'major' in newStep2Choice: print 'You cannot use the terms \'commander\', \'lieutenant\' or \'major\' in the name.

However, when it returned the output of the function, it returns 'major a'. I went through this with a debugger, yet I still can't seem to find where the problem occurred. Thanks for any help, Jasper

• Configuring visual subversion to exclude

  - by douglasrahn

  I have been searching for any documentation on how to exclude files for visual svn but have not found any. All the documentation I find seems to not match my file structure or I am missing some files/directories referenced. For example the only file I find with configuration items in it seems to be completely commented out and missing the miscellaneous section as well as any auto properties enable - etc... Ultimately I need to exclude some files so that my development can continue without SVN errors. I am constantly receiving errors for pbuser and other project files and would like to make sure this is not causing some of my other headaches. Here is information I would love to use but cant as it doesnt match: How to “fix” Subversion in XCode 3 Posted on December 10, 2008 by Rodney Aiglstorfer in Xcode If you don’t take the necessary steps to prepare for subversion, you will run into problems using it in XCode. This is because XCode produces files that “confuse” Subversion because it either thinks they are text files when they are really binary files or the reverse. To overcome these limitations, you need to make some simple changes to the subversion configuration file in your user home directory. Here are some steps you can follow to ensure that you will be able to use Subversion within XCode without any issues. Step 1. Open the subversion configuration file ~/.subversion/config NOTE: If the “.subversion” directory doesn’t exist yet then run this command which fails but will create the necessary files to get you started: svn status Step 2. Enable “global-ignores” and add new things to ignore Find the line that contains the text “global-ignores” and append the following text: build *~.nib *.so *.pbxuser *.mode* *.perspective* What I am looking for really is how to exclude the files I know I need to for Visual subversion - it shouldnt be different really from regular svn as it claims to use the same product just places a gui on it.

• Managing server instance identity on EC2

  - by kikibobo

  I recently brought up a cluster on EC2, and I felt like I had to invent a lot of things. I'm wondering what kinds of tools, patterns, ideas are out there for how to deal with this. Some context: I had 3 different kinds of servers, so first I created AMIs for each of them. The first AMI had zookeeper, so step one in deploying the system was to get the zookeeper server running. My script then made a note of the mapping between EC2's completely arbitrary and unpredictable hostnames, and the zookeeper server. Then as I brought up new instances of the other 2 kinds of servers, the first thing I would do is ssh to the new server, and add the zookeeper server to its /etc/hosts file. Then as the server software on each instance starts up, it can find zookeeper. Obviously this is a problem that lots of people have to solve, and it probably works a little bit differently in different clouds. Are there products that address this concept? I was pretty surprised that EC2 didn't provide some kind of way to tie your own name to its name. Thanks for any ideas.

• CSS - background-size: cover; not working in Firefox

  - by Jayant Bhawal

  body{ background-image: url("./content/site_data/bg.jpg"); background-size: cover; background-repeat: no-repeat; font-family: 'Lobster', cursive; } Check: http://demo.jayantbhawal.in on firefox browsers, NOT in widescreen mode. The code works on Chrome(Android + PC) and even the stock Android browser, but NOT Firefox(Android + PC). Is there any good alternative to it? Why is it not working anyways? Googled this issue a lot of times, but no one else seems to have this problem. Is it just me? In any case, how do I fix it? There are quite some questions on SO about it too, but none of them provide a legitimate solution, so can someone just tell me if they have background-size: cover; issues on firefox too? So basically tell me 3 things: 1. Why is it happening? 2. What is a good alternative to it? 3. Is this happening to you too? On Firefox browsers of course. Chrome Version 35.0.1916.114 m Firefox Version 29.0.1 Note: I may already be trying to fix it so at times you may see a totally weird page. Wait a bit and reload.

• Framework or CMS for php web development?

  - by rocknroll

  Hi all, I am a C++,Unix developer who has never dabbled in web development apart from creating simple HTML pages. I am going to change that and develop a website at a personal level soon. I am going to use php,mysql on a linux machine. In this regard I am browsing through relevant literature. The language isn't a problem but reading about CMS's and frameworks is confusing. And since I am new to web development, the number of CMS's and Frameworks are overwhelming. ? My question is do I need to have knowledge of one or more CMS' and/or Frameworks like Drupal,Joomla,Zend,Wordpress etc. If yes which is the best open source CMS' and/or Framework suggested for a newbie. ?? If the answer to the above question is yes, does the choice changes if one delves into the realms of commercial web development? Note:- I will be developing on a Linux machine, using open source tools. Thanks in advance

• How do I select column(s) by their "numeric" position in a table?

  - by DulcimerDude

  I am trying to select columns by their "x" position in the table. DBI my $example = $hookup->prepare(qq{SELECT This,That,Condition,"I also want COLUMN-10" FROM tbl LIMIT ? ?}); ###column_number=10 ordinal_position?? $example->execute('2','10') or die "Did not execute"; Is this possible or do I need to run another single select to just that column? One problem I encountered was with a col named "Condition". For some reason, when I tried to select Condition the execute would die. I never attempted but, What if the column name was SELECT? Another note is the table is 75 cols wide and I only need 50 of them. The Col names are pretty verbose so, I would like to just call them by their "position". This would also allow the col names to be changed in the future without having to change the select statement. I am quite the newbie so please explain any answers down to my level. Thanks for any assistance..

• How to align all fields as label width grows

  - by TheCloudlessSky

  I have a form where the labels are on the left and the fields on the right. This layout works great when the labels have small amounts of text. I can easily set a min-width on the labels to ensure they all have the same distance to the fields. In the first picture below, this works as expected. A problem arises when the label's text becomes too long, it'll either overflow to the next line or push the field on the same line over to the left (as seen in picture 2). This doesn't push the other labels so it is left with a "jagged" look. Ideally, it should like to style it as picture 3 with something like the following markup: <fieldset> <label>Name</label><input type="text" /><br /> <label>Username</label><input type="text" /> </fieldset> I created a jsFiddle to show the issue. Of course, the easy cross-browser way to solve this would be to use tables. That just creates tag-hell for something that should be so simple. Note: this does not need to support IE6.

• Mercurial: Class library that will exist for both .NET 3.5 and 4.0?

  - by Lasse V. Karlsen

  I have a rather big class library written in .NET 3.5 that I'd like to upgrade to make available for .NET 4.0 as well. In that process, I will rip out a lot of old junk, and rewrite some code to better take advantage of the new classes and support in .NET 4.0 (like TPL.) The class libraries will thus diverge, but still be similar enough that some bug-fixes can be done to both in the same manner. How should I best organize this class library in Mercurial? I'm using Kiln (fogbugz) if that matters. I'm thinking: Named branches in one repository, can then transplant any bugfixes from one to the other Unnamed branches in one repository, can also transplant, but I think this will look messy Separate repositories, will have to reimplement the bugfixes (or use a non-mercurial-integraded compare tool to help me) What would you do? (any other alternatives that I haven't though of is welcome as well.) Note that the class libraries will diverge pretty heavily in areas, I have some remnants of old collection-type code that does something similar to Linq that I will remove, and some code that uses it that I will rewrite to use the Linq-methods instead. As such, just copying the project files and using #if NET40..#endif sections is not going to work out. Also, the 3.5 version of the class library will not be getting many new features, mostly just critical bug-fixes, so keeping both versions equally "alive" isn't really necessary. Thus, separate copies of all the files are good enough.

• One-to-many Associations Empty Columns Issue (Ext on Rails)

  - by Joe

  I'm playing with rewriting part of a web application in Rails + Ext. However, I'm having trouble getting an associated models' name to display in the grid view. I've been able to successfully convert several models and arrange the views nicely using tabs and Ext's layout helpers. However, I'm in the middle of setting up an association -- I've followed along with Jon Barket's tutorial on how to do this using Ext -- and I've made all the Rails and JS changes suggested (with appropriate name changes for my models,) the result being that the combo box is now being correctly populated with the names of the associated models, and changes are actually written correctly to database, BUT the data doesn't show up in the column, it's just empty. However, the correct data is there in the 'detail' view. Really just wondering if anyone else ran into this, or had any thoughts on what could be happening. Definitely willing to post code if requested; just note that (AFAIK) my changes follow the tutorial pretty closely. Thanks in advance! UPDATE: Alright, slight progress - kind of. I can get the associated model id # displaying properly -- just by modifying the column model slightly. But I can't get the virtual attribute displayed in the main table (in Jon's example it's country_name.) It still goes blank when I change the data source for that column from dataIndex: 'model[associated_model_id]' to dataIndex: 'virtual_attributes[associated_model_name]' ANOTHER UPDATE: Bump. Has NOBODY here tried integrating Ext with Rails?
