  • Get the UIWindow which is under the UIActionSheet

    - by Georgi
    I am trying to present a new UIViewController on top of the current current UIViewController. Here is the line of code that creates the desired effect: LoginViewController *loginViewController = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil]; UIViewController *rootController = [[[UIApplication sharedApplication] keyWindow] rootViewController]; [rootController presentViewController:loginViewController animated:YES completion:nil]; The problem is that I added an UIActionSheet which asks the user to confirm the desired action (which is to log out). When the user confirms the action I run the above mentioned peace of code, but the UIActionSheet is still the keyWindow. Therefore the LoginViewController is not presented on top (the rootController is null when I try to debug). My question is: Can I somehow find the UIWindow which is under the UIActionSheet and from there get the root controller,or maybe I can dismiss programmatically the UIActionSheet when the users selects the log out action and only then execute the above code? Thank you in advance!

  • Fastest way to do mass update

    - by user356004
    Let’s say you have a table with about 5 million records and a nvarchar(max) column populated with large text data. You want to set this column to NULL if SomeOtherColumn = 1 in fastest possible way. The brute force UPDATE does not work very well here because it will create large implicit transaction and take forever. Doing updates in small batches of 50K records at a time works but it’s still taking 47 hrs to complete on beefy 32 core/64GB server. Is there any way to do this update faster? Are there any magic query hints/table options that scarifies something else (like concurrency) in exchange of speed? NOTE: Creating temp table or temp column is not an option because this nvarchar(max) column involves lots of data and so consumes lots of space!

  • How to save many to many fields by using an auto complete text box

    - by iHeartDucks
    If I have two models like class Author(models.Model): name = models.CharField(max_length=100) title = models.CharField(max_length=3, choices=TITLE_CHOICES) birth_date = models.DateField(blank=True, null=True) def __unicode__(self): return self.name class Book(models.Model): name = models.CharField(max_length=100) authors = models.ManyToManyField(Author) I can render the book form using a model form like this class BookForm(ModelForm): class Meta: model = Book widgets = { 'authors' : TextInput() } The authors fields is now rendered as a text box and I want to use an auto complete (where I can enter multiple authors) text box to populate the field. I am having a hard time to understand how I can save the authors in view function? I am thinking of using a hidden field to record all the author id's but I am having a hard time figuring out how to save it on the postback.

  • How to unset delegate on UIView setAnimationDelegate: call?

    - by morticae
    I am receiving crash reports that appear to be from a UIView animation calling a delegate that has been dealloced. Thread 0 Crashed: 0 libobjc.A.dylib 0x334776f6 objc_msgSend + 18 1 UIKit 0x31c566c4 -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] 2 UIKit 0x31c565d2 -[UIViewAnimationState animationDidStop:finished:] 3 QuartzCore 0x30045a26 run_animation_callbacks I am setting the current view controller as the delegate for animations using the following pattern: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:0.5]; [UIView setAnimationDelegate:self]; ... [UIView commitAnimations]; My question is, how do I set that delegate reference to nil in my dealloc method? Is there some way to retain a reference to an animation? Or fetch animations in progress?

  • ASP.NET MVC Binding issue

    - by user295541
    Hi, I have an object with a property called "name". This object has a sub object that has a property called "name" as well. Transaction.name Transaction.TransactionItem TransactionItem.name I bind Transaction object to a partial control as usual: Html.TextBox("name", Model.name)% Model is a Transaction object. And I bind TransactionItems: < if (Model.mtTransactionItem != null) { foreach (var item in Model.mtTransactionItem) { % <%= Ajax.ActionLink(item.name, "ShowItem", new { id = item.id }, new AjaxOptions { UpdateTargetId = "dialog-form" })% And when I update the one of the transaction items through an ajax call I pass the entire transaction object to the partial view. When I debug I check the Model.name property, and it has a proper value. But on the page shows the name of TransactionItem value instead of the name of Transaction value. What do I do wrong? I have checked this problem in MVC 1.0 and MVC 2.0 framework.

  • Pass Data to Data Template Selector

    - by Michael Sync
    How do you guys pass the data (parameter) to DataTemplate Selector? The only one that I can think of is to use an attached property in DataTemplate Selector? Example: public class DisableWeekendsSelection : DataTemplateSelector { [System.Diagnostics.CodeAnalysis.SuppressMessage("Microsoft.Usage", "CA2211:NonConstantFieldsShouldNotBeVisible", Justification = "DependencyProperty")] public static readonly DependencyProperty Parameter = DependencyProperty.RegisterAttached("Parameter", typeof(ObservableCollection<Date>), typeof(DisableWeekendsSelection), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public static ObservableCollection<Date> GetParameter(DependencyObject dp) { return dp.GetValue(Parameter) as ObservableCollection<Date>; } public static void SetParameter(DependencyObject dp, ObservableCollection<Date> value) { dp.SetValue(Parameter, value); } public override DataTemplate SelectTemplate(object item, DependencyObject container) { The problem with this approach is that I'm not able to get the value of Parameter in SelectTemplate method. Any suggestion would be appreciated. Thanks in advance.

  • PopupWindow with GridView - Trouble with inflating view

    - by k_day
    I am having an issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows: LayoutInflater inflater = (LayoutInflater)this.getSystemService (Context.LAYOUT_INFLATER_SERVICE); final GridView popupview = (GridView) inflater.inflate (R.layout.gridviewpopup, null, false); popupview.setAdapter(new ImageAdapter(this)); would like this GridView to popup on a button click. Also inside of my activity's onCreate, I have: final Button addButton = (Button) findViewById(R.id.add); addButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { PopupWindow mwindow = new PopupWindow(popupview, 100, 100); mwindow.showAtLocation(findViewById(R.id.main), Gravity.CENTER, 100, 100); mwindow.setFocusable(true); } }); On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int). Can anyone please explain to me what I am doing wrong?

  • Print gif using java on a 4x6" paper

    - by Wienczny
    What is the best way in Java to print a gif given as byte[] or ByteArrayInputStream on a paper with a size of 4x6 inches? This: PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet(); aset.add(new MediaSize(4, 6, Size2DSyntax.INCH)); aset.add(new Copies(1)); PrintService[] pservices = PrintServiceLookup.lookupPrintServices(DocFlavor.INPUT_STREAM.GIF, aset); DocPrintJob printJob = pservices[0].createPrintJob(); Doc doc = new SimpleDoc(sap.getGraphicImageBytes(), DocFlavor.INPUT_STREAM.GIF, null); printJob.print(doc, aset); does not work because the MediaSize is not a PrintRequestAttribute. This should be almost the same as in Package javax.print Description

  • Add comma-separated value of grouped rows to existing query

    - by Peter Lang
    I've got a view for reports, that looks something like this: SELECT a.id, a.value1, a.value2, b.value1, /* (+50 more such columns)*/ FROM a JOIN b ON (b.id = a.b_id) JOIN c ON (c.id = b.c_id) LEFT JOIN d ON (d.id = b.d_id) LEFT JOIN e ON (e.id = d.e_id) /* (+10 more inner/left joins) */ It joins quite a few tables and returns lots of columns, but indexes are in place and performance is fine. Now I want to add another column to the result, showing comma-separated values ordered by value from table y outer joined via intersection table x if a.value3 IS NULL, else take a.value3 To comma-separate the grouped values I use Tom Kyte's stragg, could use COLLECT later. Pseudo-code for the SELECT would look like that: SELECT xx.id, COALESCE( a.value3, stragg( xx.val ) ) value3 FROM ( SELECT x.id, y.val FROM x WHERE x.a_id = a.id JOIN y ON ( y.id = x.y_id ) ORDER BY y.val ASC ) xx GROUP BY xx.id What is the best way to do it? Any tips?

  • Capture window close event

    - by -providergordienko.vladimir
    I want to capture events that close editor window (tab) in Visual Studio 2008 IDE. When I use dte2.Application.Events.get_CommandEvents(null, 0).BeforeExecute I successfully captured such events: File.Close File.CloseAllButThis File.Exit Window.CloseDocumentWindow and others. If code in window is not acceptable, I stop the event (CancelDefault = true). But if I click "X" button on the right hand side, "Save Changes"; dialog appears, tab with editor window close and I have no any captured events. In this case I can capture WindowClosing event, but can not cancel the event. Is it poosible to handle "x" button click and stop event?

  • ASP.NET MVC unit test controller with HttpContext

    - by user299592
    I am trying to write a unit test for my one controller to verify if a view was returned properly, but this controller has a basecontroller that accesses the HttpContext.Current.Session. Everytime I create a new instance of my controller is calls the basecontroller constructor and the test fails with a null pointer exception on the HttpContext.Current.Session. Here is the code: public class BaseController : Controller { protected BaseController() { ViewData["UserID"] = HttpContext.Current.Session["UserID"]; } } public class IndexController : BaseController { public ActionResult Index() { return View("Index.aspx"); } } [TestMethod] public void Retrieve_IndexTest() { // Arrange const string expectedViewName = "Index"; IndexController controller = new IndexController(); // Act var result = controller.Index() as ViewResult; // Assert Assert.IsNotNull(result, "Should have returned a ViewResult"); Assert.AreEqual(expectedViewName, result.ViewName, "View name should have been {0}", expectedViewName); } Any ideas on how to mock the Session that is accessed in the base controller so the test in the descendant controller will run?

  • ASP.NET MVC - Custom validation message for value types

    - by Giovanni Galbo
    When I use UpdateModel or TryUpdateModel, the MVC framework is smart enough to know if you are trying to pass in a null into a value type (e.g. the user forgets to fill out the required Birth Day field) . Unfortunately, I don't know how to override the default message, "A value is required." in the summary into something more meaningful ("Please enter in your Birth Day"). There has to be a way of doing this (without writing too much work-around code), but I can't find it. Any help? EDIT Also, I guess this would also be an issue for invalid conversions, e.g. BirthDay = "Hello".

  • Checking to see if a generic class is inherited from an interface

    - by SnOrfus
    I've got a class that inherits from an interface. That interface defines an event that I'd like to subscribe to in the calling code. I've tried a couple of things, but they all resolve to false (where I know it's true). How can I check to see if a class implements a specific interface. Here's what I've tried (note, the object in question is a usercontrol that implements MyInterface, stored in an array of controls, only some of which implement MyInterface - it is not null): if (this.controls[index].GetType().IsSubclassOf(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType().IsAssignableFrom(typeof(MyInterface))) ((MyInterface)this.controls[index]).Event += this.Handler; if (this.controls[index].GetType() == typeof(MyInterface)) ((MyInterface)this.controls[index]).Event += this.Handler; All to no avail.

  • TelerikProfileProvider with custom Membership Provider

    - by Larsenal
    I've setup two membership providers: my custom provider and the Sitefinity provider. My custom membership provider is set as the default. I want to use Sitefinity's Profile provider for both sets of users. However, the profile provider only seems to work for the users that I pull out of the Sitefinity membership provider. After poking around with Reflector a bit, it seems that the Telerik Profile Provider assumes that the username exists in its own DB. User userByName = this.Application.GetUserByName(userName); if (userByName != null) { // magic happens here... } All the magic only happens if it was able to retrieve the user locally. Seems to violate the principles of the providers. Shouldn't I be able to arbitrarily add properties to any user regardless of the membership provider? (I've also posted this on the Sitefinity forum, but haven't got a response yet. SO has spoiled me. I've come to expect an answer in minutes, not days.)

  • C# - setting a property by reflection with a string value

    - by David Hodgson
    Hi, I'd like to set a property of an object through reflection, with a value of type string. So, for instance, suppose I have a Ship class, with a property of Latitude, which is a double. Here's what I'd like to do: Ship ship = new Ship(); string value = "5.5"; PropertyInfo propertyInfo = ship.GetType().GetProperty("Latitude"); propertyInfo.SetValue(ship, value, null); As is, this throws an Argument exception (Object of type 'System.String' cannot be converted to type 'System.Double'). How can I convert value to the proper type, based on propertyInfo?

  • How to remove accent characters from an InputStream

    - by Samuh
    I am trying to parse a Rss2.0 feed on Android using a Pull parser. XmlPullParser parser = Xml.newPullParser(); parser.setInput(url.open(), null); The prolog of the feed XML says the encoding is "utf-8". When I open the remote stream and pass this to my Pull Parser, I get invalid token, document not well formed exceptions. When I save the XML file and open it in the browser(FireFox) the browser reports presence of Unicode 0x12 character(grave accent?) in the file and fails to render the XML. What is the best way to handle such cases assuming that I do not have any control over the XML being returned? Thanks.

  • WPF dependency property setter not firing when PropertyChanged is fired, but source value is not cha

    - by Sandor Davidhazi
    I have an int dependency property on my custom Textbox, which holds a backing value. It is bound to an int? property on the DataContext. If I raise the PropertyChanged event in my DataContext, and the source property's value is not changed (stays null), then the dependency property's setter is not fired. This is a problem, because I want to update the custom Textbox (clear the text) on PropertyChanged, even if the source property stays the same. However, I didn't find any binding option that does what I want (there is an UpdateSourceTrigger property, but I want to update the target here, not the source). Maybe there is a better way to inform the Textbox that it needs to clear its text, I'm open to any suggestions.
