• Edit and create nodes in a view?

  - by tputkonen

  We are storing people's class attendance information to Drupal. We would like to show this in a grid/chart, where the first column of each row shows person's name, and rest of the columns (ca. 20) either a checkbox or "X" if the user attended a class, or otherwise an non-checked box or empty column: (dates here) Jack X XXX X X Jill XX XXX XX It should also be possible to edit the attendance information on the grid. Each attendance information is a node of its own. This functionality can probably mostly be achieved using views and editablefields, but there is one problem: if a person has not attended a specific class he/she will not have at all an attendace node for that day. What would be the easiest way to create an attendace node in those cases, so that it would be possible for the end user to edit the grid by just clicking on the checkbox or typing an 'X'?

• How to search on a array and display the items on tableview using a searchbar?

  - by skiria

  Hi, I would like to search on a arrays hierachy and display the results on a tableview. The tableview is empty when we run the app and the, when we search it, the data is written. What's the best way to do this? I read tutorials wich explains how it search on a tableview, but i want to search in all of arrays hierachy. I have 3 classes class video //iVars to allocate the video metadata NSInteger videoID; NSString *nameVideo; NSString *nameCategory; NSString *nameTopic; NSString *user; NSString *date; NSString *description; NSString *urlThumbnail; NSString *urlVideo; class Topic NSInteger TopicId; NSString nameTopic; NSMutableArray videos; class Category NSInteger CategoryId; NSString nameCategory NSMutableArray topics AppDelegate NSMutableArray categories

• avmutablecomposition insertEmptyTimeRange

  - by smartfaceweb

  I have created an avmutablecomposition and tried to use insertEmptyTimeRange to generate 1 minute of silence. This doesn't appear to be working. I have also tried creating an avmutablecompositiontrack using addMutableTrackWithMediaType:preferredTrackID: and then insertEmptyTimeRange on the track and still no success. To give some background on my app, I allow users to add audio samples a timeline and then playback or export and this is working really well using the av classes. The problem is that I need to make sure that the audio is exactly 1 min (for example). Regardless of the info about my specific app above, is it possible to insert an empty time range into a comp or comptrack?

• Jenkins Build fails when artifacts are not there

  - by leifg

  I use Jenkins to run some integration tests on a web appilcation (using cucumber, capybara and selenium) Everytime a test fails, a screenshot, the HTML source and a video of the process is saved. the path structure looks like this: results/output/<test_name>/<files> I use the archive artifacts feature of Jenkins to provide the files (pattern: results/output/*/*). It works great. However as soon as a build succeeds, there are no screenshots/videos etc... and the build fails because Jenkins cannot find the files for the pattern. Is there a way to tell Jenkins to succeed without having the files present? I don't want to do a dirty hack which involves creating an empty folder structure like result/output/success/hooray.txt.

• Codeigniter Form Validation - how to unset form values after success?

  - by BrynJ

  I realise this request goes against the example provided in the CI documentation (which advises a separate 'success' page view), but I would like to reutilise a given form view after a form has been successfully submitted - displaying a success message then displaying a blank form. I've tried a few ways unsuccessfully to clear the validation set values (unsetting $_POST, setting rules / fields to an empty array and rerunning validatio). I could redirect to the same page, but then I'd have to set a session variable to display a success message - which is a messy approach. Any ideas how to achieve the above?

• Visual Studio 2008, MSBuild: "replacement" projects

  - by liori

  Hello, My solution has a library project which needs a special environment to be built (lots of external libraries and tools)... but it is not vital to our application. We'd like to avoid installing these tools when not necessary (most of our developers work on other parts of code). We have created another project which has the same API, but has an empty implementation and is compilable without those external tools. I'd like to be able to easily switch between those projects and still get all the references in other projects correct. I don't know VS/MSBuild very well, but willing to learn whatever is necessary. Is it possible? I am looking for ideas... We're using Subversion, and solutions involving some hacks inside VCS are also welcome.

• ASP.NET MVC - How do I implement validation when using Data Repositories? (Visual Basic)

  - by rockinthesixstring

  I've built a UserRepository interface to communicate with my LINQ to SQL Data layer, but I'm trying to figure out how to implement validation. Here is what my AddUser subroutine looks like Public Sub AddUser(ByVal about As String, ByVal birthdate As DateTime, ByVal openid As String, ByVal regionid As Integer, ByVal website As String) Implements IUserRepository.AddUser Dim user = New User user.About = about user.BirthDate = birthdate user.LastSeen = DateTime.Now user.MemberSince = DateTime.Now user.OpenID = openid user.RegionID = regionid user.UserName = String.Empty user.WebSite = website dc.Users.InsertOnSubmit(user) dc.SubmitChanges() End Sub And then my controller will simply call AddUser(...) But I haven't the foggiest idea on how to implement both client side and server side validation on this. (I think I would prefer to use jQuery AJAX and do all of the validation on the server, but I'm totally open to opinions)

• Adding a searchbar to display array items on a tableview?

  - by skiria

  I want to build an app that shows a empty tableview. Then users can write a text on a searchbar and when they click on Search button the tableview will be written with array items founded. I've see this tutorial: link text, but I only need to search when user click SearchButton. How can I do this? What methods do i have to use? I've tried with this method, but it doesn't works. - (void) searchBarSearchButtonClicked:(UISearchBar *)theSearchBar { NSInteger nVideos = [appDelegate.allVideos count]; NSLog(@"number of videos: %i", nVideos);

• Control webcam from C#

  - by Moulde

  Hi I have a Creative Life CAM Optia AF webcam, the software included in the package is able to control the camera in different ways, like set autofocus to auto or manual, and a bunch of gamma and brightness settings. I'm capturing the feed with the AForge Computer vision library, and it's working great. But i would like to be able to set the manual focus from inside my application. Ive been searching for a tutorial, but come up empty handed. Can i somehow either disassemble the included software, or is there some way to fetch the traffic / instructions being sent to the device? Thanks in advance.

• Link redirects to "show" action instead of the indicated in routes.rb

  - by Brian Roisentul

  I'm working with Ruby on rails 2.3.4 and I'd like to have a link that executes an action when clicked. The relevant part of the routes.rb file looks like this: map.search_filter_relevance "/anuncios/buscar", :controller => 'announcements', :action => 'search_filter_relevance' My view(it's the model's index page) looks like this: <%= link_to 'M&Aacute;S RELEVANTES', search_filter_relevance_path %> And my controller looks like this: def search_filter_relevance raise params.inspect unless params[:announcements].nil? or params[:announcements].empty? @announcements = params[:announcements].order_by_featured end end The problem is that when I click the link I get an error due to some null value in the Show action! I'm not accessing that action at all...why is executing it?

• concatenating results from SQL query and NULL columns

  - by Curtis

  I need to concatenate several columns of a table into a single value, then show that value in an asp dropdownlist. The SQL code I'm issuing is as follows: SELECT UserID, CustomerNum, UserName + ' - ' + UserAddress + ',' + UserCity + ' ' + UserState AS UserInfo FROM Users WHERE (CustomerNum = @CustomerNum) ORDER BY UserName I then set 'UserInfo' as the text field in the dropdownlist. This generally works, except occasionally one of the columns in the database is null (for example, UserState). When that happens, the entire concatenation is null, and I get an empty entry in the dropdownlist. Is there something in SQLServer that will allow me to ignore those NULL results, or will I have to code something up in the DataBind event? Thanks

• LinkButton child controls render

  - by Alex

  Hi. I want to have a LinkButton that adds 'span' tag around the text. protected override void Render(HtmlTextWriter writer) { Text = String.Concat("<span>", Text, "</span>"); base.Render(writer); } It's works perfectly, but only if I add text like this: <cc:TestLinkButton ID="TestLinkButton" runat="server" Text="SomeText"> </cc:TestLinkButton> If I want to add some image I will write something like this: <cc:TestLinkButton ID="LinkButton1" runat="server"> <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/icon_holiday.png" BorderWidth="0" /> SomeText </cc:TestLinkButton> In this case Text property will be empty, because actualy "SomeText" is child control property. So question is is how to add tag around child controls.

• mootools 1.1.1 scrollto element with class name ... anything like jquery?

  - by dtour

  I get the impression mootools will do this, but in a roundabout way. I am working with livevalidation script. What I want to achieve is when the from runs and errors are generated then the page will scroll to the first error found. This will be outputted as: <span class=" LV_validation_message LV_invalid">Can't be empty!</span> with jquery I could do the following: $.scrollTo($('span.LV_invalid:1')); I get the feeling in mootools I have to first find the position of the first span with class LV_invalid then pass this to the scrollTo function or is there a much simpler solution?

• Hashbytes comparison in stored proceduring not matching record

  - by Michael Itzoe

  The password field in my user table (SQL Server 2008) is encrypted using HASHBYTES on insertion. I have a stored procedure with parameters for the username and plain-text password which does a SELECT using that username and the password sent through HASHBYTES, then returns the user record if it finds a match. The SP is always returning an empty recordset, but if I copy and paste just the SELECT from the SP to a new query window, it returns the matched record. There're no other statements in the SP. I'm missing something here; what is it?

• How do I clear a WebView's content before loading a page?

  - by Mark

  I have an embedded WebView in my Cocoa application in which I load an external web page. Each time the user clicks on a button, the view opens and shows the page. The problem is that the second time the user opens the WebView, the previous page is still visible. Instead I'd like to show a blank/empty page (together with a progress indicator). How can I clear a WebView before loading a new page? The closest solution I could find was to call this: [webView stringByEvaluatingJavaScriptFromString:@"document.open();document.close()"]; Is there a better way to do this? Thanks!

• Check if key exists in $_SESSION by building index string

  - by Kim

  I need to check if a key exists and return its value if it does. Key can be an array with subkeys or endkey with a value. $_SESSION['mainKey']['testkey'] = 'value'; var_dump(doesKeyExist('testkey')); function doesKeyExist($where) { $parts = explode('/',$where); $str = ''; for($i = 0,$len = count($parts);$i<$len;$i++) { $str .= '[\''. $parts[$i] .'\']'; } $keycheck = '$_SESSION[\'mainKey\']' . $str; if (isset(${$keycheck})) { return ${$keycheck}; } // isset($keycheck) = true, as its non-empty. actual content is not checked // isset(${$keycheck}) = false, but should be true. ${$var} forces a evaluate content // isset($_SESSION['mainKey']['testkey']) = true } What am I doing wrong ? Using PHP 5.3.3.

• How can I run a function anytime anything is animated with jQuery?

  - by WillyCornbread

  Hi - I have some jQuery animations in my code to slide divs up and down in response to some mouse clicks and other logic. This is all working just peachy, however in IE 6 some of the smaller icon images on the page don't slide along with the rest of the div for some strange reason. They kind of stay put then flicker into the new position and I've chalked this up to an IE6 'feature'. Considering that I have to support IE6, I wanted to just hide the icons anytime an animation started, and show them again when the queue was empty. I couldn't find a reference to any kind of events or hooks into the queue itself and I'd rather not add the hide code, then the show code to every animation as a callback. Thanks if you can help- b

• Pattern or recommneded refactoring for method

  - by iKode

  I've written a method that looks like this: public TimeSlotList processTimeSlots (DateTime startDT, DateTime endDT, string bookingType, IList<Booking> normalBookings, GCalBookings GCalBookings, List<DateTime> otherApiBookings) { { ..... common process code ...... while (utcTimeSlotStart < endDT) { if (bookingType == "x") { //process normal bookings using IList<Booking> normalBookings } else if (bookingType == "y") { //process google call bookings using GCalBookings GCalBookings } else if (bookingType == "z" { //process other apibookings using List<DateTime> otherApiBookings } } } So I'm calling this from 3 different places, each time passing a different booking type, and each case passing the bookings I'm interested in processing, as well as 2 empty objects that aren't used for this booking type. I'm not able to get bookings all into the same datatype, which would make this easier and each booking type needs to be processed differently, so I'm not sure how I can improve this. Any ideas?

The span_col attribute in the first 'BANNER_TEXT' sequence indicates which elements by position in the 2nd sequence are related. An example: 'Years in Practice' would be the first key and the attribute SPAN_COL=3 for that element indicates it would contain '< 11 years', '11-20 years', '21-30 years' (the first grouping of string.empty = Total would be skipped).

• Expiring an IE session using WatiN

  - by Steve Wilkes

  I'm trying to write an acceptance test using WatiN which checks that a user is redirected to the login page if they navigate to a page after their session times out. I'm using WatiN's IE class for the browser, and trying the following: // 1. Login // 2. Do this: Browser.ClearCookies(); Browser.ClearCache(); // 3. Navigate to a different page But the user is always still logged in. Other info: I'm running the test through the NUnit GUI running as an administrator It's an ASP.NET MVC 3 site, using forms authentication and in-process session state I'm using IE9. If I manually clear all cookies in Chrome, the user is logged out If I manually clear all cookies in IE the user stays logged in If I call Browser.Eval("alert(document.cookie)"); in IE it alerts an empty string Given the above, I'm assuming this is a quirk with IE; any ideas how I can work around it?
