  • Trouble using xib files in libraries

    - by flohei
    Hi there, I'm having some trouble working with libraries and included xib files. Let me explain my situation first. I've got a project that's running pretty good. Now I need a part of my project as a library for another customer who want's to use some of the functionality in his app. I've created a library with help of that highly recommended article. My customer should be able to initialize a main view controller like this: LibraryMainViewController *lmvc = [[LibraryMainViewController alloc] initWithNibName:@"LibraryMainViewController.xib" bundle:foo]; That for sure leads to an error when I try to present that view controller modally. I'm not sure what bundle I have to use here. I tried something like [NSBundle bundleForClass:[SomeClassInTheLibrary class]]; but that didn't solve the problem. I would be glad if someone could tell me how to actually use a xib file in that kind of situation. Thanks –f

  • Setting a form field's value during validation

    - by LaundroMat
    I read about this issue already, but I'm having trouble understanding why I can't change the value of a form's field during validation. I have a form where a user can enter a decimal value. This value has to be higher than the initial value of the item the user is changing. During clean(), the value that was entered is checked against the item's previous value. I would like to be able to re-set the form field's value to the item's initial value when a user enters a lower value. Is this possible from within the clean() method, or am I forced to do this in the view? Somehow, it doesn't feel right to do this in the view... (To make matters more complicated, the form's fields are built up dynamically, meaning I have to override the form's clean() method instead of using the clean_() method).

  • exporting html table multi line columns to excel multi line cells

    - by Passat
    I have a html table in a view MVC4 that I am sending to excel as output. Inside the view page I have some columns that have multiple lines that are built with forloops within the HTML. What's the best way to add the or \r\n so that excel renders it correctly? I have a table and inside I build each row looping thru a recordset. In each row I also loop thru different recordsets to populate columns within each row so that some of the columns may contain more than one value and they should show in different lines in the table that will export to excel.

  • why does the gingerbread emulator orientation gets stuck in apps?

    - by tabjsina
    At first I thought this was a problem with my app, but it seems to be happening in any app (though interestingly, not the home screen) in the gingerbread emulator. To replicate my issue, open eclipse and fire up the android emulator for gingerbread (I'm using the "Google APIs - API Level 9" as my target) So the procedure to duplicate once the emulator loads is press LCtrl-F11 to shift orientation to landscape, then again to switch to portrait Result: In the homescreen: The view rotates to landscape, and then back to portrait, as expected In any app (i've tried browser, calculator, maps, and the app i'm currently working on): the view rotates to landscape, and then nothing, it stays in landscape even the emulator is displaying the phone in landscape mode (see below) http://i54.tinypic.com/2ake06v.jpg Has anyone else had this issue, or have I installed the emulator in some incorrect way - this hasn't been an issue with any of the previous emulators

  • SQL Analysis Services - Dimension attributes with a "many" cardinality

    - by MonkeyBrother
    I am creating a cube with the following tables: Customer CustomerID, Name Customer Rep CustomerID, RepID Rep RepID, Name The important thing here is that there is a many to many relationship between Reps and Customers. I want to be able to ask the question "How much sales for customers working with rep 'A'?" In the data source view i set up the relationships between both customerid columns and both repid columns. I set up the rep attribute in the dimension builder and when I try to build the cube I get this error: Errors in the high-level relationship engine. the 'Rep' table that is required for a join cannot be reached based on the relationships in the data source view.

  • MVC partial page update

    - by GB
    Hello, I have an MVC project where I have a form with fields a user can enter and save. On that same page I have a table which shows a brief listing of information that the user just saved. The problem I am having is trying to update only the table after a save and not an entire page refresh. Is this possible in jquery or MVC? If so does anyone have an example. Here is what the action in the controller looks like: public ActionResult RefreshList() { string _employeeID = Request.QueryString["empIDSearch"]; this.ViewData["coursehistorylist"] = _service.ListCoursesByEmpID(_employeeID); return View("CourseHistoryList"); } The function in the view: (and this is where I'm confused on how to update only the table) $.ajax({ url: "/Home/RefreshList", type: "POST", success: function(result) { alert("got here"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.status + " " + thrownError + " " + ajaxOptions); } }); Thanks.

  • How can I see included JavaScript sources?

    - by Toddintr
    I am trying to script a web page using GreaseMonkey. (I am using Firebug for help in development.) The page has a small amount of JavaScript code, but that code pulls in other JS files from the site. Are the entire collection of JS files stored somewhere on the client side (i.e. on the filesystem somewhere) so that I can view them? Or better yet, is there a way I can view them in Firebug? I am a little overwhelmed by Firebug but will be able to follow instructions. Many thanks. (My first ever question on SO!) -Todd

  • touchesEnded:withEvent: from UIScrollView First Responder

    - by Matthew Mitchell
    I've made a UIScrollView the first responder. I need to maintain touch events to a touchesEnded:withEvent: method on a view behind it. I've tried using the nextResponder method and that failed. I've tried forwarding touchesEnded:withEvent to the view behind it and that fails. How do I get this to work? The UIScrollView wont work unless it is the first responder or gets events some other way. Thank you for any help. Shame Apple's documentation and APIs are terrible in areas.

  • How to draw or put a text on empty an UITableViewController ?

    - by elementsense
    Hi I have a app that starts with a empty UITableViewController, which is pretty .. well, emtpy. Now I was wondering if I could hint the user by painting something else on the view, like pointing an arrow to the plus button and say something like "press here to add something new" I'll guess I have to do this in the viewDidLoad method, where I also init my NSFetchedResultsController, so I actually know if there are any objects in my list. I never put controls on the screen by code so I am not sure where to start and where to put em on. will that be the [self view] ? Thanks

  • how to call context menu

    - by gdonald
    I open my context menu like this: private OnClickListener optionsClickListener = new OnClickListener() { public void onClick( View v ) { registerForContextMenu( v ); openContextMenu( v ); } }; How can I call registerForContextMenu( v ); openContextMenu( v ); from inside my regular menu handler here: public boolean onOptionsItemSelected( MenuItem item ) { switch( item.getItemId() ) { case OPTIONS: registerForContextMenu( v ); openContextMenu( v ); return true; where I have no View to pass?

  • VS2010 - shortcuts for web controls and HTML snippets

    - by p.campbell
    Consider the feature in Visual Studio 2010 for snippets in the HTML Source view of a web page. type a control name in plaintext with no markup or brackets! ... e.g. hyperlink. Then hit Tab Your web control has been auto-completed for you. It's up to you to fill in the other details that you need. This works for form as well: <form action="default.aspx" method="post"> </form> This looks like a real time saver. This is supported in WebForms and ASP.NET MVC projects. What other snippets are available in Visual Studio 2010 in the Source view of a page?

  • Change UIView alpha value

    - by Ask
    I'm trying to create an UIView and change its alpha property to simulate backlight change. Here is my code if (TransparentView == nil) { TransparentView = [[UIView alloc] initWithFrame:self.view.bounds]; TransparentView.backgroundColor = [UIColor whiteColor]; self.view = TransparentView; } start=start+appDelegate.OnOffTime; TransparentView.alpha = 0.2; float step = 1.0 / ( appDelegate.OnOffTime * 100); for (float f = 0; f < 1; f=f+step) { TransparentView.alpha = (CGFloat)(1 - f); [NSThread sleepForTimeInterval:0.01]; } Both TransparentView.alpha = 0.2 and TransparentView.alpha = (CGFloat)(1 - f) do change TransparentView.alpha, but only TransparentView.alpha = 0.2 changes real device "brightness'. What am I doing wrong?

  • In ASP.NET MVC, how does response.redirect work?

    - by Swoop
    I have used response.redirect in classic ASP and ASP.NET webforms. However, with MVC 2.0, I am running into something peculiar. I have a private method in a controller class that is used by multiple controller methods to help load and validate some information. This private method is setup to redirect if a problem is discovered to a generic error message page. The big problem I am noticing is that the calling controller class and page view attempt to complete rendering and loading before the redirect actually takes place. This is annoying in development because the View throws exceptions that I need to ignore before my generic error page finally loads. As mentioned above, I am used to the older model of response.redirect which prevented subsequent code on a page from being executed as the new page would then load. Any help or advice on redirects in MVC would be greatly appreciated.

  • Getting a random element in Django

    - by Sarah
    I just finished the Django tutorial and started work on my own project, however, I seem to have missed something completely. I wanted to get a random slogan from this model: from django.db import models class Slogan(models.Model): slogan = models.CharField(max_length=200) And return it in this view: from django.http import HttpResponse from swarm.sloganrotator.models import Slogan def index(request): return HttpResponse(Slogan.objects.order_by('?')[:1]) However, the view just returns 'Slogan object'. Then I thought, maybe I can access the slogan string itself by simply appending .slogan to the slice, but that gives me an error indicating that the object I have is actually a QuerySet and has no attribute slogan. I've obviously misunderstood something about Django here, but it just doesn't fall into place for me. Any help?

  • How can keep track of the index path of a button in a tableview cell?

    - by Jake
    I have a table view where each cell has a button accessory view. The table is managed by a fatchedresults controller and is frequently reordered. I want to be able to press a button and be able to obtain the index path of the pressed button's tableviewcell. I've been trying to get this working for days by storing the row of the button in it's tag, but when the table get's reordered the row becomes incorrect and I keep failing at reordering the tags correctly when a change is made. Any new ideas on how to keep track of the button's cell's index path? Thanks so much for any help.

  • Delete/move a UITableView row that's attached to a web service.

    - by Kevin L.
    Deleting or moving rows for a UITableView that is backed with local data (e.g., NSArray) is easy and instantaneous: Remove the value from the array. Call deleteRowsAtIndexPaths:withRowAnimation:. Profit! But my table view communicates with a web service, which means once the "Delete" button on that row gets tapped, I have to forward a request on to the server (via ASIHTTPRequest, of course), get the response, and then tell the table view to run its little delete-row animation, all with a few seconds of latency in between. From a high-level, what's the best way to do that? Throw some callback selector into ASIHTTPRequest's userInfo dictionary? KVO? Bonus points for some nice UI touch, like some kind of spinner on the soon-to-be-deleted cell.

  • How to specify ingredients in Schema.org (other than recipes or drugs)?

    - by guillem
    I'd like to use Schema.org for a series of product specs pages. The products are cosmetics (shampoos, creams, etc.) and ideally an INCI declaration will be included for every product. I'd like to use Schema.org in the declaration, but I cannot find a suitable category in Schema.org. Ingredients is meant for cooking recipes, and ActiveIngredient for (medical) drugs and dietary supplements. Did I overlook some part of the tree? Any ideas for a workaround? Or am I trying to do something out of scope?

  • How do I change text color on the selected row inside a ListView/GridView? (using Expression Dark th

    - by Thiado de Arruda
    I'm using theExpression Dark WPF Theme(http://wpfthemes.codeplex.com/) with a ListView(view property set to a GridView) to display some user data like the following : <ListView Grid.Row="1" ItemsSource="{Binding RegisteredUsers}" SelectedItem="{Binding SelectedUser}" > <ListView.View> <GridView> <GridViewColumn Header="Login" DisplayMemberBinding="{Binding Login}" Width="60"/> <GridViewColumn Header="Full Name" DisplayMemberBinding="{Binding FullName}" Width="180"/> <GridViewColumn Header="Last logon" DisplayMemberBinding="{Binding LastLogon}" Width="120"/> <GridViewColumn Header="Photo" Width="50"> <GridViewColumn.CellTemplate> <DataTemplate> <Image Source="{Binding Photo}" Width="30" Height="35"/> </DataTemplate> </GridViewColumn.CellTemplate> </GridViewColumn> </GridView> </ListView.View> </ListView> The rows have white text with a dark background and white background when selected, however the text color doesnt change when selected and it makes very difficult to read, I would like the text to have a dark color when the row is selected. I have searched for a way to style the text color but with no success, here is the control template for the ListViewItem : <Border SnapsToDevicePixels="true" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" CornerRadius="2" x:Name="border"> <Grid Margin="2,0,2,0"> <Rectangle x:Name="Background" IsHitTestVisible="False" Opacity="0.25" Fill="{StaticResource NormalBrush}" RadiusX="1" RadiusY="1"/> <Rectangle x:Name="HoverRectangle" IsHitTestVisible="False" Opacity="0" Fill="{StaticResource NormalBrush}" RadiusX="1" RadiusY="1"/> <Rectangle x:Name="SelectedRectangle" IsHitTestVisible="False" Opacity="0" Fill="{StaticResource SelectedBackgroundBrush}" RadiusX="1" RadiusY="1"/> <GridViewRowPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" Margin="0,2,0,2" VerticalAlignment="Stretch" /> </Grid> </Border> The trigger that changes the background color simply applies an animation to change the 'SelectedRectangle' opacity, but I cant change the text color on the same trigger(I tried using a setter for the foreground color on the ListViewItem, but with no success). Does someone have a clue on that?
