  • Problems with multi-line comments jquery

    - by c0mrade
    Hello, I'm making a image website with a bunch of images on the website, and below every image there is possibility of commenting the image and after that comments gets displayed without page loading and the comment content, the problem is when I have long comments which break the current line they don't get displayed since my comment box css overflow is hidden. Here is example : This is a comment - This is displayed properly This is a comment This is a comment This is a comment - this is not displayed properly since it break line. Here is the jQuery code for this : $.ajax({ type: "POST", url: "<?=base_url()?>imagesform/post_comment", data: datas, success: function () { $("#image-comments-" + image_id).attr("class", "comments"); $("#image-comments-" + image_id).append("<li id=\"new_append_" + image_id+ "\">" + $("#image").find(".comment").val() + "</li>").children(':last').height($('.comments li:last').height()).hide().slideDown(500, function () { var bodyHeight = $('html').height(); $('.addComment').fadeOut(300, function () { $('html').height(bodyHeight); }); }); alert($("#image").find(".comment").val()); } }); Here the $("#image").find(".comment").val() is the value of the text-area in which comment is inputted, when I alert it the whole multi line input is there put its not being appended to the li properly, that is part when I get confused, any suggestions why only part of the inputted string is appended?

  • Struts2 jQuery Plugin Autocompleter renders HTML with style attributes <== changing this?

    - by Tim
    I'm using the Struts2 jQuery plugin 2.1 and render an autocompleter in my JSP. Here's the code: <s:form id="search-form" action="search" theme="simple"> <s:url id="remoteurl" action="jsonlanguages"/> <div> <sj:autocompleter cssClass="bgstandardelement empty" id="languages" name="echo" href="%{remoteurl}" delay="50" value="Search..." /> <input type="submit" id="search-button" value="GO" /> </div> </s:form> No matter what theme I set the autocompleter-form to, the HTML rendered for the list I output is always an unordered list with a style element that I cannot override. It has the following stype-attribute: style='z-index: 1; top: 242px; left: 926px; display: none; width: 256px'; As I want another outfit for my list, this doesn't work. Putting in the following attribute has no effect: cssStyle="width:115px!important;" What can I do?

    - by Claudiu
    I want to change php variable ($start and $end called by var b1 and var b2) if the user clicks on button. Now I know that php is server side, but how can I do it? I read something about using $get but I don't know how to implement it: <?php if ( is_user_logged_in() ) { ?> <input type="submit" value="Start Chat" id="start_chat" style="position: absolute; top: 30px; left: 10px;" /> <?php } ?> <script> jQuery('#start_chat').click(function(){ $(this).data('clicked', true); }); var b1 = '<?php echo $start; ?>'; var b2 = '<?php echo $end; ?>'; if(jQuery('#start_chat').data('clicked')) { // change var b1 and b2 } else { // do not change anything } </script> <div id="eu_la"> <?php $start = strtotime('9:30'); $end = strtotime('12:30'); $timenow = date('U'); if((date('w') == 4) && ($timenow >= $start && $timenow <= $end)) { // day 2 = Tuesday include('facut_mine.php'); } else { do_shortcode('[upzslider usingphp=true]'); } ?>

  • Assigning a value to an integer in a C linked list

    - by Drunk On Java
    Hello all. I have a question regarding linked lists. I have the following structs and function for example. struct node { int value; struct node *next; }; struct entrynode { struct node *first; struct node *last; int length; }; void addnode(struct entrynode *entry) { struct node *nextnode = (struct node *)malloc(sizeof(struct node)); int temp; if(entry->first == NULL) { printf("Please enter an integer.\n"); scanf("%d", &temp); nextnode->value = temp; nextnode->next = NULL; entry->first = nextnode; entry->last = nextnode; entry->length++; } else { entry->last->next = nextnode; printf("Please enter an integer.\n"); scanf("%d", nextnode->value); nextnode->next = NULL; entry->last = nextnode; entry->length++; } } In the first part of the if statement, I store input into a temp variable and then assign that to a field in the struct. The else branch, I tried to assign it directly which did not work. How would I go about assigning it directly? Thanks for your time.

  • Pitfalls of the Architecture - Database based HTTP Request/Response Parsing

    - by Sam
    We have a current eCommerce Site that runs on ASP.NET and we hired a consultant to develop an new site bases on SOA. The new site architecture is as follows Web Application : Single Page Web Application (built on javascript/jquery templates - do not use any MVVM frameworks) that uses some javascript thrown all over the place. Service Layer : Very very light Service Layer that does not do anything other than calling a single stored procedure and pass in the entire http request. Database : The entire site content is in the database. The database does the heavy lifting of parsing the request and based on the HTTP method and some input parameter calls the appropriate Store Procedures or views and renders the result in JSON/XML. We have been told by them that this is built on latest and greatest technologies. I have a lot of concerns and of them given are the few Load on the Database SEO concerns for single page application as this is a public facing website Scalablity? Is this SOA? Cross Browser compatability (Site does not work in < IE9) Realistic implementaion of Single page application I know something is not right but I just need to validate my concerns here. Please help me.

  • replacing elements horizontally and vertically in a 2D array

    - by wello horld
    the code below ask for the user's input for the 2D array size and prints out something like this: (say an 18x6 grid) .................. .................. .................. .................. .................. .................. code starts here: #include <stdio.h> #define MAX 10 int main() { char grid[MAX][MAX]; int i,j,row,col; printf("Please enter your grid size: "); scanf("%d %d", &row, &col); for (i = 0; i < row; i++) { for (j = 0; j < col; j++) { grid[i][j] = '.'; printf("%c ", grid[i][j]); } printf("\n"); } return 0; } I now ask the user for a string, then ask them where to put it for example: Please enter grid size: 18 6 Please enter word: Hello Please enter location: 0 0 Output: Hello............. .................. .................. .................. .................. .................. Please enter location: 3 4 Output: .................. .................. .................. ..Hello........... .................. .................. program just keeps going. Any thoughts on how to modify the code for this? PS: Vertical seems way hard, but I want to start on horizontal first to have something to work on.

  • NVelocity (or Velocity) as a stand-alone formula evaluator

    - by dana
    I am using NVelocity in my application to generate html emails. My application has an event-driven model, where saving and/or updating of objects causes these emails to be sent out. Each event can trigger zero, one or multiple multiple emails. I want to be able to configure which emails get sent out at run-time without having to modify code. I was thinking I could leverage the NVelocity #if() directive to do this. Here is my idea... Step 1) Prior to email sending, the administrator must configure a formula for NVelocity to evaluate. For example: $User.FirstName == "Jack" Step 2) When an object is saved or created, build an NVelocity template in memory based on the input formula. For example: String formula = GetFormulaFromDB(); // $User.FirstName == "Jack" String templ = "#if( " + formula + ") 1 #else 0 #end"; Step 3) Execute the NVelocity engine in memory against the template. Check the results to see if we have to send the email: String result = VelocityMerge(templ); // utility function if( result.Trim() == "1" ) { SendEmail(); } I know this is not exactly what NVelocity was intended to do, but I think it just might work :) One of the benefits of doing things this way is that the same syntax can be used for the formula as is used inside the template. Does anybody have any words of caution or suggestions? Is there a way to execute the #if() directive without jumping through hoops like I have above? Is there a recommended way to validate the formula syntax ahead of time? Thanks.

  • Strange offset space between <button> as parent container and <div> as child.

    - by Maxja
    I need to decorate a standard html button. The base element I took <button> instead of <input>, cos I decided that the element must be a parent container. And there is child element <div> in it. This <div> element will be been the core element for decoration, and should occupy the entire space of the parent element - button. <button> <div>*decoration goes here*</div> </button> And within Cascading Style Sheets it might be looks like this: css button { margin: 0; border: 0; padding: 0; width: *150*px; height: *50*px; position: relative; } div { margin: 0; border: 0; padding: 0; width: 100%; height: 100%; background: *black*; position: absolute; top: 0; left: 0; } html <button type="button"> <div>*decoration goes here*</div> </button> So, Opera(10) is doing well, webkits Chrome(6) and Safari(4) is doing also well, but Internet Explorer(8) is bad - DOM Inspector shows some strange Offset space in top and left, FireFox(3) is also bad - DOM Inspector shows that <div> get some negative value in css-property right: and bottom:. Even if this property will set to zero(0) DOM-Inspector still shows same negative value. I almost broke my brain. Help me, solve this problem, please!

  • C Map String to Function

    - by Scriptonaut
    So, I'm making a Unix minishell, and have come to a roadblock. I need to be able to execute built-in functions, so I made a function: int exec_if_built_in(char **args) It takes an array of strings(the first being the command, and the rest being arguments). For non built-in commands I simply use something like execvp, however I need to find a way to map the first string to a function. I was thinking of making two arrays, one of strings, and another with their corresponding function pointers. However, since many of these functions will be different(return and accept different things), this approach won't work. I also thought of making an array of structs with a name property and a function pointer property, however once again due to the varied nature of the functions I'll be using, this won't work. So, what's the best way to execute a function based on the input of a string? How do I map a string to a certain function? I'm not very familiar with function pointers so I may be missing something. Thank you guys for the help :)

  • Javascript Regex: Testing string for intelligent query

    - by Shyam
    Hi, I have a string that holds user input. This string can contain various types of data, like: a six digit id a zipcode that contains out of 4 digits and two alphanumeric characters a name (characters only) As I am using this string to search through a database, the query type is determined on the type of search, which i want to handle serverside using JavaScript (yes, I am using JavaScript serverside). Searching on StackOverflow, brought me some interesting information, like the .test-method, which seems perfect for my needs. The test-method returns either true or false based on the evaluation on the string using a regex object. I am using this page as a reference: http://www.javascriptkit.com/jsref/regexp.shtml So I am trying to determine the zipcode, by using the following very noobish regex. var r = /[A-Za-z]{2,2}/ As far I can understand, this should limit the amount of occurrences of alphanumeric characters to a maximum of two. See beneath the output of my JavaScript console. > var r = /[A-Za-z]{2,2}/ > var x = "2233AL" > r.test(x) true > var x = "2233A" > r.test(x) false > var x = "2233ALL" > r.test(x) true /* i want this to be false */ > A little help would be really appreciated!

  • Create SQL parameters programmatically

    - by Neo
    Another annoying one for me but probably something simple. I have a number of possible where clauses for a query based on user input, my question is how can I add these programmatically? For instance: wherequery = @"WHERE fieldname = @p_FieldName AND "; if (txtValue.textLength > 0){ wherequery += "fieldname2 = @p_FieldName2 AND "; } query = @"SELECT * FROM tabe" + wherequery; sql = connection.CreateCommand(); sql.CommandText = query; How would I go about doing the parameters for that? I've tried ArrayLists, Dictionaries and a few other methods but can't find a way of doing it. Ideally I'd want to do something like this: SqlParameter[] sqlparams; wherequery = @"WHERE fieldname = @p_FieldName AND "; if (txtValue.textLength > 0){ wherequery += "fieldname2 = @p_FieldName2 AND "; sqlparams.Parameters.Add("@p_FieldName2 ", SqlDbType.VarChar).Value = txtValue.text; } query = @"SELECT * FROM tabe" + wherequery; sql = connection.CreateCommand(); sql.CommandText = query; sql.Parameters.Add(sqlparams);

  • When to define SDD(System Sequence Diagram) operations System->Actor?

    - by devoured elysium
    I am having some trouble understanding how to make System Sequence Diagrams, as I don't fully grasp why in some cases one should define operations for System - Actor and in others don't. Here is an example: Let's assume the System is a Cinema Ticket Store and the Actor is a client that wants to buy a ticket. 1) The User tells the System that wants to buy some tickets, stating his client number. 2) The System confirms that the given client number is valid. 3) The User tells the System the movie that wants to see. 4) The System shows the set of available sessions and seats for that movie. 5) The System asks the user which session/seat he wants. 6) The User tells the System the chosen session/seat. This would be converted to: a) -----> tellClientNumber(clientNumber) b) <----- validClientNumber c) -----> tellMovieToSee(movie) d) <----- showsAvailableSeatsHours e) -----> tellSystemChosenSessionSeat(session, seat) I know that when we are dealing with SDD's we are still far away from coding. But I can't help trying to imagine how it how it would have been had I to convert it right away to code: I can understand 1) and 2). It's like if it was a C#/Java method with the following signature: boolean tellClientNumber(clientNumber) so I put both on the SDD. Then, we have the pair 3) 4). I can imagine that as something as: SomeDataStructureThatHoldsAvailableSessionsSeats tellSystemMovieToSee(movie) Now, the problem: From what I've come to understand, my lecturer says that we shouldn't make an operation on the SDD for 5) as we should only show operations from the Actor to the System and when the System is either presenting us data (as in c)) or validating sent data (such as in b)). I find this odd, as if I try to imagine this like a DOS app where you have to put your input sequencially, it makes sense to make an arrow even for 5). Why is this wrong? How should I try to visualize this? Thanks

  • How to load two divs into separate targets with JQuery?

    - by Bussard
    Hi all, I'm trying to achieve two things, both of which I fail to get at. On a server are a series of notes; all contain a div (id=ajxContent). Some notes also contain an additiona div (id=ajxHead). The ajxContent itself contains links (class=clicking) to call the next installment, hence the link destination in a variable. This is my code: $(document).ready(function(){ $( 'a.clicking' ).live('click', function(e){ e.preventDefault(); var theLink = $(this).attr('href'); $('#loadText').load(theLink + '#ajxContent'); $('h1').load(theLink + '#ajxHead'); }); }) Where it fails: 1) the ajxContent gets loaded into the h1 tag as well as in its intended target. 2) when I had set up the code differently, if there was no div id=ajxHead present in a note, the load would nevertheless erase the existing value in the h1 tag. Am I on a totally wrong track here, with two load statements? Input is very welcome, thanks.

  • Is it not possible to make a C++ application "Crash Proof"?

    - by Enno Shioji
    Let's say we have an SDK in C++ that accepts some binary data (like a picture) and does something. Is it not possible to make this SDK "crash-proof"? By crash I primarily mean forceful termination by the OS upon memory access violation, due to invalid input passed by the user (like an abnormally short junk data). I have no experience with C++, but when I googled, I found several means that sounded like a solution (use a vector instead of an array, configure the compiler so that automatic bounds check is performed, etc.). When I presented this to the developer, he said it is still not possible.. Not that I don't believe him, but if so, how is language like Java handling this? I thought the JVM performs everytime a bounds check. If so, why can't one do the same thing in C++ manually? UPDATE By "Crash proof" I don't mean that the application does not terminate. I mean it should not abruptly terminate without information of what happened (I mean it will dump core etc., but is it not possible to display a message like "Argument x was not valid" etc.?)

  • Handling nulls in Datawarehouse

    - by rrydman
    I'd like to ask your input on what the best practice is for handling null or empty data values when it pertains to data warehousing and SSIS/SSAS. I have several fact and dimension tables that contain null values in different rows. Specifics: 1) What is the best way to handle null date/times values? Should I make a 'default' row in my time or date dimensions and point SSIS to the default row when there is a null found? 2) What is the best way to handle nulls/empty values inside of dimension data. Ex: I have some rows in an 'Accounts' dimensions that have empty (not NULL) values in the Account Name column. Should I convert these empty or null values inside the column to a specific default value? 3) Similar to point 1 above - What should I do if I end up with a Facttable row that has no record in one of the dimension columns? Do I need default dimension records for each dimension in case this happens? 4) Any suggestion or tips in regards to how to handle these operation in Sql server integration services (SSIS)? Best data flow configurations or best transformation objects to use would be helpful. Thanks :-)

  • How to allow devise users to edit their profil?

The update fails. How can I do this ? I'm quite lost. Thanks by advance.

  • How can I automate new system provisioning with scripts under Mac OS X 10.6?

    - by deeviate
    I've been working on this for days but simply cannot find the correct references to make it work. The idea is to have a script that will baseline newly purchased Macs that comes into the company with basic stuffs like set autologin to off, create a new admin user (for remote admins to access for support, set password to unlock screensaver and etc) . Sample list for baseline that admins have to do on each new machine: Click the Login Options button Set Automatic Login: OFF Check: Show the Restart, Sleep, and Shutdown buttons Uncheck: Show input menu in login window Uncheck: Show password hints Uncheck: Use voice over in the login window Check: Show fast user switching menu as Short Name (note: this is only part of a long list to do on each machine) I've managed to find some references to make some parts work. Like autologin can be unset with: defaults write /Library/Preferences/.GlobalPreferences com.apple.userspref.DisableAutoLogin -bool TRUE and I've kinda found ways to muscle in a new user creation (including prompts) with AppleScript and shell commands. But generally its tough finding ways to do somewhat simple things like turn on password to get out of screensaver or to allow fast user switching. References are either too limited or just no where to be seen (e.g. I can unset autologin via cli but the very next setting on the system preference "show restart, sleep and shutdown buttons" is somewhere else and I can't find any command line to make it set) Does anyone have any ideas on a list, document, reference or anything of where each setting on the system resides so that I can be pointed to make it work? or maybe sample scripts for the above example... My thanks for reading thus far—a huge thank you for whoever that has any info on the above.

  • SCons and dependencies for python function generating source

    - by elmo
    I have an input file data, a python function parse and a template. What I am trying to do is use parse function to get dictionary out of data and use that to replace fields in template. Now to make this a bit more generic (I perform the same action in few places) I have defined a custom function to do so. Below is definition of custom builder and values is a dictionary with { 'name': (data_file, parse_function) } (you don't really need to read through this, I simply put it here for completeness). def TOOL_ADD_FILL_TEMPLATE(env): def FillTemplate(env, output, template, values): out = output[0] subs = {} for name, (node, process) in values.iteritems(): def Process(env, target, source): with open( env.GetBuildPath(target[0]), 'w') as out: out.write( process( source[0] ) ) builder = env.Builder( action = Process ) subs[name] = builder( env, env.GetBuildPath(output[0])+'_'+name+'_processed.cpp', node )[0] def Fill(env, target, source): values = dict( (name, n.get_contents()) for name, n in subs.iteritems() ) contents = template[0].get_contents().format( **values ) open( env.GetBuildPath(target[0]), 'w').write( contents ) builder = env.Builder( action = Fill ) builder( env, output[0], template + subs.values() ) return output env.Append(BUILDERS = {'FillTemplate': FillTemplate}) It works fine when it comes to checking if data or template changed. If it did it rebuilds the output. It even works if I edit process function directly. However if my process function looks like this: def process( node ): return subprocess(node) and I edit subprocess the change goes unnoticed. Is there any way to get correct builds without making process functions being always invoked?

  • C++ STL question related to insert iterators and overloaded operators

    - by rshepherd
    #include <list> #include <set> #include <iterator> #include <algorithm> using namespace std; class MyContainer { public: string value; MyContainer& operator=(const string& s) { this->value = s; return *this; } }; int main() { list<string> strings; strings.push_back("0"); strings.push_back("1"); strings.push_back("2"); set<MyContainer> containers; copy(strings.begin(), strings.end(), inserter(containers, containers.end())); } The preceeding code does not compile. In standard C++ fashion the error output is verbose and difficult to understand. The key part seems to be this... /usr/include/c++/4.4/bits/stl_algobase.h:313: error: no match for ‘operator=’ in ‘__result.std::insert_iterator::operator* [with _Container = std::set, std::allocator ]() = __first.std::_List_iterator::operator* [with _Tp = std::basic_string, std::allocator ]()’ ...which I interpet to mean that the assignment operator needed is not defined. I took a look at the source code for insert_iterator and noted that it has overloaded the assignment operator. The copy algorithm must uses the insert iterators overloaded assignment operator to do its work(?). I guess that because my input iterator is on a container of strings and my output iterator is on a container of MyContainers that the overloaded insert_iterator assignment operator can no longer work. This is my best guess, but I am probably wrong. So, why exactly does this not work and how can I accomplish what I am trying to do?
