  • CSS to Replace Table Layout for Forms

    - by Erick
    I've looked at other questions and am unable to find the solution to this. Consider this image: I want to wrap divs and stack them vertically. The GREEN div would be a wrapper on a line. The BLUE div would contain an html label and maybe icon for a tooltip. The ORANGE div would contain some sort of entry (input, select, textarea). Several of these would be stacked vertically to make up a form. I am doing this now, but I have to specify a height for the container div and that really needs to change depending on the content - considering any entry could land there. Images and other stuff could land here, as well. I have a width set on the BLUE div and the ORANGE is float:left. How can I get rid of the height on divs and let that be determined by content? Is there a better way? Changing all to something else would be difficult and would prefer a way to style all elements or something. The code I'm using is like: <div class=EntLine> <div class=EntLbl> <label for="Name">Name</label> </div> <div class=EntFld> <input type=text id="Name" /> </div> </div> The CSS looks like: .EntLine { height: 20px; position: relative; margin-top: 2px; text-align: left; white-space: nowrap; } .EntLbl { float: left; width: 120px; padding: 3px 0px 0px 3px; min-width: 120px; max-width: 120px; vertical-align: text-top; } .EntFld { float: left; height: 20px; padding: 0px; width: 200px; } Thanks!

  • jScrollPane jEditable DOM problems

    - by Kyle Lafkoff
    Hello world, I am having a funky problem. See (this link won't disappear): www.skitzo.org/~el/bugjeditable.png for the firebug output screenshot. Here's my code. I run getJSON() to fetch the info from the PHP which pulls from DB and I fill a div with the result. I have jScrollPane and jEditable so a user can scroll down and click to edit any of the content. It works sometimes and then it doesn't work which makes me wonder if the browser is not interpreting the code properly or if I am misunderstanding fundamental DOM concepts here.... Here is a live current version of the code: http://www.musedates.com/testing.php $().ready(function() { $('#pane1').jScrollPane(); $('#tab_journal').tabs(); $('#tab2').load("/journal_new.php"); var i=0; var row = ''; var k, v, dt; $.getJSON("/ajax.php?j=22", function(data) { row = '<p>'; while(i<data.length) { $.each(data[i], function(k, v) { if (k == 'subject') { row += '<div style="font-size:1.5em; color:#000000;"><div class="editable" style="width:705px;" id="title-'+data[i].id+'">'+v+'</div></div>posted: '+dt+'<br />'; } else if (k == 'dt') { dt = v; } else if (k == 'msg') { row += '<div class="editableMsg" style="width:705px; height:40px;" id="msg-'+data[i].id+'">'+v+'</div></p>'; } }); i++; } $('#pane1').append(row).jScrollPane({scrollbarWidth:10, scrollbarMargin:10, showArrows:true}); }); $('.editable').livequery(function () { $('.editable').editable("/savejournal.php", { submitdata : function() { }, tooltip : 'Click to edit', indicator : '<img src="/UI/images/indicator.gif">', cancel : 'Cancel', submit : 'OK' }); $('.editableMsg').editable("/savejournal.php", { submitdata : function() { }, tooltip: 'Click to edit', indicator : '<img src="/UI/images/indicator.gif">', cancel : 'Cancel', submit : 'OK', type : 'textarea' }); $(".editable,.editableMsg").mouseover(function() { $(this).css('background-color', '#FDD017'); }); $(".editable,.editableMsg").mouseout(function() { $(this).css('background-color', '#fff'); }); }); }); And then the HTML: <div id="tab_container" style="margin:0px 0px 2px 8px;"> <ul id="tab_journal"> <li><a href="#tab1"><span>View / Edit</span></a></li> <li><a href="#tab2"><span>New Entry</span></a></li> </ul> </div> <div id="tab1" style="margin:0px 0px 0px 8px;"> <div id="pane1" class="scroll-pane super-wide"></div> </div> <div id="tab2" style="margin:0px 0px 0px 8px; width:700px;"></div> Thanks world.

  • Consuming SharePoint Web Services fails when behind Proxy server

    - by Jan Petersen
    Hi All, I've seen a number of post about consuming Web Services from behind a proxy server, but none that seams to address this problem. I'm building a desktop application, using Java, JAX-WS in NetBeans. I have a working prototype, that can query the server for authentication mode, successfully authenticate and retrieve a list of web site. However, if I run the same app from a network that is behind a proxy server (the proxy does not require authentication), then I'm running into trouble. The normal -dhttp.proxyHost ... settings does not seam to help any. But I have found that by creating a ProxySelector class and setting it as default, I can regain access to the authentication web service, but I still can't retrieve the list of web sites from the SharePoint server. Anyone have any experience on how to make this work? I have put the source text java class files of a demo app up, showing the issue at the following urls (it's a bit to long even in the short demo form to post here). link text When running the code from a network behind a proxy server, I successfully retrieve the Authentication mode from the server, but the request for the Web Site list generates an exception originating at: com.sun.xml.internal.ws.transport.http.client .HttpClientTransport.readResponseCodeAndMessage(HttpClientTransport.java:201) The output from the source when no proxy is on the network is listed below: Successfully retrieved the SharePoint WebService response for Authentication SharePoint authentication method is: WINDOWS Calling Web Service to retrieve list of web site.

  • IE adding a attribute 'done[number]' ??

    - by Phil Jackson
    Hi all im struggling to find an answer to my problem here. I've made a IM application the same as facebooks but it is having problems in IE. The problem started as I kept seeing rn at the beginnning of every post made via IE. That was due to stripslashes function. But as I was investigating I noticed my tag was being added an attribut 'done'; <li><UL done67="7">rn<LI class=name>ACTwebDesigns</LI>rn<LI class=speech>hello</LI></UL></li> <li><UL done1="4">rn<LI class=name>ACTwebDesigns</LI>rn<LI class=speech>foo</LI></UL></li> <li><UL done84="10">rn<LI class=name>ACTwebDesigns</LI>rn<LI class=speech>barr</LI>rn<LI class=speech ?>foobar</LI></UL></li> <li><UL done88="14">rn<LI class=name>ACTwebDesigns</LI>rn<LI class=speech>this is a test</LI></UL></li> does anyone know of a reason why IE would add this attribute? EDIT: function checkForm() { $(".chat_input").keydown(function(e){ if ( e.keyCode == 13 ) { var data = strip_tags($(this).val()); var username = $("#users_username").val(); var box = $(this).parents('div:eq(0)'); $(this).val(""); if( box.find('.conversation_box li.' + session_number ).length == 0 ) { var conversation_list = box.find('.conversation_box').html(); var insert_data = '<li class="' + session_number + '"><ul><li class="name">' + username + '</li><li class="speech">' + data + '</li></ul></li>'; box.find('.conversation_box').html(conversation_list + insert_data); bottom(); }else{ var conversation_list = box.find('.conversation_box li.' + session_number + ' ul').html(); var insert_data = '<li class="speech"">' + data + '</li>'; box.find('.conversation_box li.' + session_number + ' ul').html(conversation_list + insert_data); bottom(); } return false; } }); } function store_chat(){ try{ var token = $("#token").val(); var openedBoxes = $("li.conversation_list"); openedBoxes.each(function(){ var boxContainer = $(this).parents('div:eq(0)'); var amount = boxContainer.find('.conversation_box li').length; var p = boxContainer.find('.open_trigger').html(); var u = $("#users_username").val(); if( amount != 0 ){ if( $(this).parents('div:eq(0)').find('.conversation_box li.' + session_number ).length != 0 ) { var session_contents = $(this).parents('div:eq(0)').find('.conversation_box li.' + session_number ).html(); alert( session_contents ); $.ajax({ type: 'POST', url: './', data: 'token=' + token + '&re=7&s=' + amount + '&sd=' + session_contents + '&u=' + u + '&p=' + p, cache: false, timeout: 5000, success: function(html){ auth(html); boxContainer.find('.conversation_box').html(html); bottom(); } }); } } }); }catch(er){} }

  • Volunteer for a potential employer?

    - by EoRaptor013
    I've been looking for work since March, and haven't had much luck. Recently, however, I interviewed with a small company near my home for a C#, .NET, SQL development position. I hit it off very well with the hiring manager during the phone screen, and even more so during the face to face. Unfortunately, I failed the practical test: wiring up a web form, creating a couple of SQL stored procedures, saving new data with validation, and creating a minimal search screen. I knew what I was doing, but I was too slow to meet their standards as all the work needed to be done within an hour. Nevertheless, I really liked the place, the environment, the people who I would have been working with, and the boss. (I gave the company an 11 on Joel's 12 point scale.) So, the obvious next step was to scrape the rust off. I've been trying to create little projects for myself, but I don't know that I've been effective in getting any faster. What with all that goes into creating a project, I'm not heads-down coding as much as I think I need. Now, with all that introduction, here's the question. I have been thinking about calling the hiring manager at that place, and asking him to let me volunteer for three or four weeks, with no strings attached. I think it would benefit me, and wouldn't cost him anything (as long as I didn't slow the existing people down!). At the end of that period, he might, or might not, be inclined to hire me, but even if not, I would have had as much as 160 hours of in the trenches development. Maybe not all shiny, but no more rust, I would think. Does this plan make any sense at all? I certainly don't want to sound desperate (although, I'm not far from being there), and I very much need the tuneup, lube, and change the oil. What's the downside, if any, to me doing this? Do any of you see red flags going up—either from the prerspective of the hiring manager, or from the perspective of a developer?

  • Modify a ListBox's item from a button in it's template?

    In my Silv erlight 3 project, I'm using a ListBox to display results of a Get() operation form a WCF WebService. The ListBox's item template is the following : <ListBox x:Name="m_listview" ItemsSource="{Binding Users, Mode=TwoWay, UpdateSourceTrigger=Default}" Foreground="{StaticResource EnergyBlue}" Background="{StaticResource EnergyBackground}" HorizontalContentAlignment="Stretch" VerticalContentAlignment="Center" Grid.ColumnSpan="3" Margin="0,0,0,2" IsSynchronizedWithCurrentItem="False"> <ListBox.ItemTemplate> <DataTemplate> <Grid MinWidth="536" MinHeight="10" d:DesignWidth="19.875" d:DesignHeight="20.75"> <Grid.ColumnDefinitions> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> <ColumnDefinition Width="0.2*"/> </Grid.ColumnDefinitions> <TextBox Text="{Binding Path=UserName, Mode=TwoWay, UpdateSourceTrigger=Default}" Grid.Column="0" Foreground="{StaticResource EnergyWhite}" Margin="2" Background="{StaticResource EnergyBackground}" BorderBrush="{StaticResource EnergyBlue}" SelectionBackground="{StaticResource EnergyBlue}" SelectionForeground="{StaticResource EnergyWhite}" MinWidth="100"/> <PasswordBox Password="{Binding Path=UserPass, Mode=TwoWay, UpdateSourceTrigger=Default}" Grid.Column="1" Foreground="{StaticResource EnergyWhite}" Margin="2" Background="{StaticResource EnergyBackground}" BorderBrush="{StaticResource EnergyBlue}" SelectionBackground="{StaticResource EnergyBlue}" SelectionForeground="{StaticResource EnergyWhite}" MinWidth="100"/> <TextBox Text="{Binding Path=UserTypeId, Mode=TwoWay, UpdateSourceTrigger=Default}" Grid.Column="2" Foreground="{StaticResource EnergyWhite}" Margin="2" Background="{StaticResource EnergyBackground}" BorderBrush="{StaticResource EnergyBlue}" SelectionBackground="{StaticResource EnergyBlue}" SelectionForeground="{StaticResource EnergyWhite}" MinWidth="100"/> <Button Style="{StaticResource EnergyGlassButton}" Grid.Column="3" MinWidth="10" MinHeight="10" Content="Update" Click="OnUpdateUser"/> <Button Style="{StaticResource EnergyGlassButton}" Grid.Column="4" MinWidth="10" MinHeight="10" Content="Remove" Click="OnRemoveUser"/> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The template contains 2 buttons.

I've tried : User target_user = m_listview.SelectedItem as User; but it turned out that the listview item wasn't selected. Can it be done without actually selecting the listview item? For instance, just click on the "remove" button and have the row disappear? Best regards

  • Connected host failed to respond (internal NAT address)

    - by MostRandom
    I'm writing my first C# web application that connects to an XML based service. It requires that I present a certificate and feed the XML stream. It seems to authenticate properly but then it gives the following error: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.1.10.4:3128 The funny thing is that I'm not on a proxy or anything like that. I'm connecting directly to the internet. At one point I we did use a proxy that with internal NAT address. So my question is: Does Visual Studio have some sort of default proxy setting that I need to change?

  • How to break a Hibernate session?

    - by Péter Török
    In the Hibernate reference, it is stated several times that All exceptions thrown by Hibernate are fatal. This means you have to roll back the database transaction and close the current Session. You aren’t allowed to continue working with a Session that threw an exception. One of our legacy apps uses a single session to update/insert many records from files into a DB table. Each recourd update/insert is done in a separate transaction, which is then duly committed (or rolled back in case an error occurred). Then for the next record a new transaction is opened etc. But the same session is used throughout the whole process, even if a HibernateException was caught in the middle. We are using Oracle 9i btw with Hibernate 3.24.sp1 on JBoss 4.2. Reading the above in the book, I realized that this design may fail. So I refactored the app to use a separate session for each record update. In a unit test with a mock session factory, I could prove that it is now requesting a new session for each record update. So far, so good. However, we found no way to reproduce the session failure while testing the whole app (would this be a stress test btw, or ...?). We thought of shutting down the listener of the DB but we realized that the app is keeping a bunch of connections open to the DB, and the listener would not affect those connections. (This is a web app, activated once every night by a scheduler, but it can also be activated via the browser.) Then we tried to kill some of those connections in the DB while the app was processing updates - this resulted in some failed updates, but then the app happily continued. Apparently Hibernate is clever enough to reopen broken connections under the hood without breaking the whole session. So this might not be a critical issue, as our app seems to be robust enough even in its original form. However, the issue keeps bugging me. I would like to know: Under what circumstances does the Hibernate session really become unusable after a HibernateException was thrown? How to reproduce this in a test? (What's the proper term for such a test?)

  • Custom Windows Forms Control not exporting functions, not showing in tools list, showing as Text

    - by flavour404
    Hi, I have written a very simple control. C# Visual Studio 2008. Its output should be, and is a dll. I have added a reference to the dll within the project that I intend to use it with. The msdn article about how to write a control states that it should appear in the 'Add reference / projects' list, which it doesn't but I simply navigated to it under the 'browse' tab, went to the /bin folder and added the reference that way. I dragged it over to my toolbox, but it shows up as a 'Text:xhair_tool' and when i try and add it to a form, it won't, so what have I done wrong? It was created as a 'Windows forms control' project. It should export the one method which is 'Target' which return an array, as shown below. using System; using System.Collections.Generic; using System.ComponentModel; using System.Drawing; using System.Data; using System.Text; using System.Windows.Forms; namespace xhair_tool { public partial class xhair : UserControl { public xhair() { InitializeComponent(); } private void xhair_Load(object sender, EventArgs e) { } protected override void OnPaint(PaintEventArgs e) { Graphics g = e.Graphics; Pen pen = new Pen(Color.Black, 1); SolidBrush redBrush = new SolidBrush(Color.Red); g.DrawLine(pen, 8, 0, 8, 7); g.DrawLine(pen, 8, 9, 8, 16); g.DrawLine(pen, 0, 8, 7, 8); g.DrawLine(pen, 9, 8, 16, 8); //ControlPaint.DrawReversibleLine(start, end, backColor) } /// <summary> /// Returns the point at the center of the crosshair /// </summary> /// <returns>int[x,y]</returns> public int[] Target { get { int[] _xy = new int[2]; _xy[0] = this.Left + 8; _xy[1] = this.Top + 8; return _xy; } } } } Thanks, R.

  • dynamically drawing polylines on googlemaps using php/mysql

    - by arc
    Hi. I am new to the googlemaps API. I have written a small app for my mobile phone that periodically updates its location to an SQL databse. I would like to display this information on a googlemap in my browser. Ideally i'd like to then poll the database periodically and if any new co-ords have arrived, add them to the line. Best way of describing it is this; http://tiny.cc/HEIa0 In a quest to get to there, i've started on the documents on google and been modifying them to try and acheive what I want.

  • Rails "NoMethodError" with sub-resources

    - by Tchock
    Hi. I'm a newbie Rails developer who is getting the following error when trying to access the 'new' action on my CityController: undefined method `cities_path' for #<#<Class:0x104608c18>:0x104606f08> Extracted source (around line #2): 1: <h1>New City</h1> 2: <%= form_for(@city) do |f| %> 3: <%= f.error_messages %> 4: 5: <div class="field"> As some background, I have a State model with many Cities. I'm getting this error after clicking on the following link coming from a State show page: <p>Add a city: <%= link_to "Add city", new_state_city_path(@state) %></p> When I run 'rake:routes' it says this is a legit route... For more background, here is the CityController 'new' action: def new @city = City.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @city } end end Here is the (complete) form in the view: <%= form_for(@city) do |f| %> <%= f.error_messages %> <div class="field"> <%= f.label :name %><br /> <%= f.text_field :name %> </div> <div class="actions"> <%= f.submit %> </div> <% end %> This initially made me think that it's a resources/routes issue since it came back with a mention of 'cities_path' (in fact, that's what another person posting to Stack Overflow had wrong (http://stackoverflow.com/questions/845315/rails-error-nomethoderror-my-first-ruby-app). However, that doesn't seem to be the case from what I can see. Here are how my resources look in my routes file: resources :states do resources :cities end I can get it working when they are not sub-resources, but I really need to keep them as sub-resources for my future plans with the app. Any help would be very much appreciated, since I've been racking my brains on this for more hours than I would care to admit... Thanks! (Not sure this matters at all, but I'm running the very latest version of Rails 3 beta2).

  • PHP script works fine until I send it a parameter from HTTPService in Flash Builder 4?

    - by ben
    I'm using a PHP script to read an RSS feed in my Flex 4 app. The script works when I put the url of the feed in the actual script, but I can't get it to work when I try to send the URL as a parameter from a HTTPService in Flex.

  • problem with jquery : minipulating val() property of element

    - by P4ul
    Hi, Please help! I have some form elements in a div on a page: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> </div> using jquery I would like to take a copy of #template, manipulate the values of the inputs and insert it after #template so the result would look something like: <div id="box"> <div id="template"> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value=""> </div> </div> <div> <label for="username">Username</label> <input type="text" class="username" name="username[]" value="paul" / > <label for="hostname">hostname</label> <input type="text" name="hostname[]" value="paul"> </div> </div> I am probably going about this the wrong way but the following test bit of javascript code run in firebug on the page does not seem to change the values of the inputs. var cp = $('#template').clone(); cp.children().children().each( function(i,d){ if( d.localName == 'INPUT' ){ $(d).val('paul'); //.css('background-color', 'red'); } }); $("#box").append(cp.html()); although if I uncomment "//.css('background-color', 'red');" the inputs will turn red.

  • XPathNavigator in Silverlight

    - by vladimir
    I have a code library that makes heavy use of XPathNavigator to parse some specific xml document. The xml document is cross-referenced, meaning that an element can reference another which has not yet been encountered during parsing: <ElementA ...> <DependentElementX id="1234"> </ElementA> <ElementX id="1234" .../> The document doesn't really look like this, but the point is that 1) there is an xml schema that enforces the overall document structure, 2) elements inside the document can reference each other using some IDs, and 3) there is quite a few such cross references between different elements in the document. The document is parsed in two phases. In the first pass I walk through the document XPathDocument doc = ...; XPathNavigator nav = doc.CreateNavigator(); nav.MoveToRoot(); nav.MoveToFirstChild()... and occasionally 'bookmark' the current position (element) in the document using XPathNavigator.Clone() method. This gives me a lightweight instance of an XPathNavigator which I can store somewhere and use later to jump back to a particular place (element) in my document. Once I have enough information collected in the first pass (for example, I have made sure there is indeed an ElementX with an id='1234'), I jump back to saved bookmarks (using those saved XPathNavigators) and complete the parsing. Well, now I'm about to use this library in Silverlight 3.0 and to my horror the XPathNavigator is not in the System.Xml assembly. Questions: 1) Am I missing something obvious (i.e. XPathNavigator does exist in some shape or form, for example in a toolkit or a freeware library)? 2) If I do have to make modifications in the code, what would be the best way to go? Ideally, I would like to make minimal changes, not to rewrite 80% of the code just to be able to use something like XLinq. To resume, in case I have to give up XPathNavigator, all I need is a way to bookmark places in my document and to get back to them so that I can continue to iterate from where I left off. Thanks in advance for any help/ideas.

  • Jqeury Validate() special function

    - by kevin
    Hi there, i'm using the Jquery validate() plugin for some forms and it goes great. The only thing is that i have an input field that requires a special validation process. Here is how it goes: The Jquery validate plugin is called in the domready for all the required fields. Here is an exemple for an input: <li> <label for="nome">Nome completo*</label> <input name="nome" type="text" id="nome" class="required"/> </li> And here is how i call my special function: <li> <span id="sprytextfield1"> <label for="cpf">CPF* (xxxxxxxxxxx)</label> <input name="cpf" type="text" id="cpf" maxlength="15" class="required" /> <span class="textfieldInvalidFormatMsg">CPF Inv&aacute;lido.</span> </span> </li> And at the bottom of the file i call the Spry function: <script type="text/javascript"> <!-- var sprytextfield1 = new Spry.Widget.ValidationTextField("sprytextfield1","cpf"); //--> </script> Of course i call the Spry css and js files in the head section as well as my special-validate.js. When i just use the Jquery validate() plugin and click on the send button, the page goes automatically back to the first mistaken input field and shows the error type (not a number, not a valid email etc.). But with this new function, this "going-back-to-the-first-mistake" feature doesnt work, of course, because the validate() function sees it all good. I already added a rule for another form (about pictures upload) and it goes like this: $("#commentForm").validate({ rules: { foto34: { required: true, accept: "jpg|png|gif" } } }); Now my question is, how can i add the special validation function as a rule of the whole validation process ? Here is the page to understand it better: link text and the special field is the first one: CPF. Hope i was clear explaining my problem. Thanks in advance. kevin

    The test case is in below. Or you can view it in jsbin: http://jsbin.com/uxagi. <!DOCTYPE html> <html> <head> <style type="text/css"> body {margin: 20px; } #main {border: 1px solid red;} img {float: left; height: 100px; padding: 0 10px 10px 0;} ul {margin: 0; padding: 0; list-style-type: none;} </style> </head> <body> <div id="main"> <ul> <li> <img src="http://upload.wikimedia.org/wikipedia/en/thumb/0/07/CranebyLinson1894.jpg/100px-CranebyLinson1894.jpg" /> <div class="content">"The Open Boat" is a short story by American author Stephen Crane. First published in 1897, it was based on Crane's experience of having survived a shipwreck off the coast of Florida earlier that year while traveling to Cuba to work as a newspaper correspondent. Crane was stranded at sea for thirty hours when his ship, the SS Commodore, sank after hitting a sandbar. He and three other men were forced to navigate their way to shore in a small boat; one of the men, an oiler named Billie Higgins, drowned. Crane subsequently adapted his report into narrative form, and the short story "The Open Boat" was published in Scribner's Magazine. The story is told from the point of view of an anonymous correspondent, Crane's fictional doppelgänger, and the action closely resembles the author's experiences after the shipwreck. A volume titled The Open Boat and Other Tales of Adventure was published in the United States in 1898. Praised for its innovation by contemporary critics, the story is considered an exemplary work of literary Naturalism. One of the most frequently discussed works in Crane's canon, it is notable for its use of imagery, irony, symbolism, and exploration of themes including survival, solidarity, and the conflict between man and nature. H. G. Wells considered "The Open Boat" to be "beyond all question, the crown of all [Crane's] work".</div> </li> </ul> </div> </body> </html> Note that in standards-compliant browsers and IE8, there is no vertical space between the red border and the text. But there is vertical space in IE7 (haven't tested in IE6).

  • function parameter used to store value

    - by user248247
    Hi, I have to define an interface. The API in my homework is stated below: int generate_codes(char * ssn, char * student_id); int denotes 0 or 1 for pass or fail. studentid is an output param should return a 6 digit id. ssn is a 9 digit input param they school program will take ssn's and use my code to generate the student id. now from an API perspective should I not be using const char * for both parameters. should the studentid not be passed in by reference? rather than by pointer? can someone tell me how i can easily use the pointer in my test app which uses my api to get the pointer such that it prints a std::string from a char *? my app code looks something like const char * ssn = "987098765" const char * studnt_id = new char [7]; int value = -1; value = generate_codes(ssn,studnt_id); std::string test(studnt_id); std::cout<<"student id= "<<test<<" Pass/fail= "<<value<<std::endl; delete [] studnt_id; return 0; I basically got an error about << not being compatible with the right hand side of the operand. When i changed the code to std::cout<<"student id= "<<test.c_str()<<" Pass/fail= "<<value<<std::endl; then it worked but i get garbage for the value. not sure how to do get the value form the pointer. THe value inside the function prints just fine. but when i try to print it outside of the function it prints garbage. Inside the above function I do set the studndt_id like so std::string str_studnt_id = studnt_id; should that make the address of the str_studnt point to the address of studnt_id and thus any changes I make to the value that its pointing to it should reflect outside the function?

  • I'm cloning a table row that contains an input that's being set to jQuery TimeEntry that errors when

    I'm adding a TimeEntry to a page where the user can add a row (clone) to a table. The row that is cloned is hidden (display:none). The user clicks a button and javascript is run to clone the row which renames all of the fields and then appends the new row to the table. <tr id="blankRowShift"> <td> <input type="text" id="timeStart" name="timeStart" /> </td> <td> <input type="text" id="timeEnd" name="timeEnd" /> </td> <td> <select id="userLevel"> <option value="0">Please Select One</option> <option value="2">Admin</option> <option value="1">Employee</option> <option value="3">Scheduler</option> </select> </td> </tr> var r = $("#tbl #blankRowShift").clone().removeAttr("id"); $("#timeStart", r).attr("name", "timeStart" + nn).attr("id", "timeStart" + nn); $("#timeEnd", r).attr("name", "timeEnd" + nn).attr("id", "timeEnd" + nn); $("#userLevel option:nth(0)", r).attr("selected", "selected"); $("#userLevel", r).attr("name", "userLevel" + nn).attr("id", "userLevel" + nn).attr("value", 0); $("#tbl").append(r); $("#timeStart" + nn).timeEntry({ show24Hours: false, showSeconds: false, timeSteps: [1, 15, 0], spinnerImage: 'includes/js/spinnerOrange.png', beforeShow: customRangeStart }); $("#timeStart" + nn).timeEntry('setTime', new Date()); $("#timeEnd" + nn).timeEntry({ show24Hours: false, showSeconds: false, timeSteps: [1, 15, 0], spinnerImage: 'includes/js/spinnerOrange.png', beforeShow: customRangeEnd }); $("#timeEnd" + nn).timeEntry('setTime', new Date()); The spinner works just fine and the times can be changed. Then when submitting the form, I validate the time. The getTime errors in jQuery with the message "elem is undefined var id = elem[ expando ];". I've placed the statement 'console.dir(input)' in the _getTimeTimeEntry: function and it returns nothing for the cloned fields. el = $("#timeStart" + i); if (el.timeEntry("getTime") == null) {
