  • C++ Direct 2D How To Resize ID2D1Bitmap

    - by Nkosi Dean
    I'm making myself a simple GUI library for a game I'm making and each control needs to have a Bitmap to draw to when the control needs redrawing. When it does not need to be redrawn, it will have an already made bitmap ready to display to the screen. Since controls can be resized, this Bitmap also needs to be resized so the control can be fully drawn into it properly. How can I achieve this since it does not appear to be a Resize method to resize a bitmap, unlike an ID2D1HwndRenderTarget, which can be resized?

  • WPF binding Ancestor

    - by JerryVienna
    Hi Experts, I have problems with bindings. I want to use a UserControl (Intellibox from codeplex) but I only get error messages in the output window. Basically I have window grid ... stuff ... usercontrol (self written) ... stuff ... usercontrol (IntelliBox) In the Output window I get following stuff: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'RelativeSource FindAncestor, AncestorType='System.Windows.Controls.UserControl', AncestorLevel='1''. BindingExpression:Path=ShowResults; DataItem=null; target element is 'Popup' (Name='IntelliboxPopup1'); target property is 'IsOpen' (type 'Boolean') The binding in the IntelliBox control is defined as follows: {Binding Path=ShowResults, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}} I guess there is a problem, cause the nesting withing usercontrols - how to I get this error fixed? Thanks!

  • ListView items not clickable with HorizontalScrollView inside

    - by Felix
    I have quite a complicated ListView. Each item looks something like this: > LinearLayout (vertical) > LinearLayout (horizontal) > include (horizontal LinearLayout with two TextViews) > include (ditto) > include (ditto) > TextView > HorizontalScrollView (this guy is my problem) > LinearLayout (horizontal) In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good. My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call). How can I make my list items clickable again?

  • Silverlight 4 MediaElement play sound

    - by NealWalters
    I converted a local sound file to a resource, which built this in my XAML: <UserControl.Resources> <my:Uri x:Key="SoundFiles">file:///c:/Audio/HebrewDemo/Shalom.wav</my:Uri> </UserControl.Resources> I did this by pasting a local disk mp3 filename into source, then clicked on the "dot" by source and chose "Extract Value to Resource". When I run, it tells me that "Uri" is not valid, and sure enough, in the Intellisense, I see other elements that start with "uri" but not just URI by itself. In the real world I want to specify a dynamic mp3 file name. For example, I might have a database of foreign language words used for flashcards, I want to play a sound file on a URL. But I thought I would try to walk before running...

  • How to convert Silverlight XAML to Resource dictionary in Silverlight 2

    - by Vecdid
    I am looking for the quickest and easiest way to combine two silverlight projects. Once has controls all in Silverlight XAML the other is template driven and uses a template based on a Silverlight resource dictionary. I am looking for some advice and resources on the best and quickest way to do this. One project is based on this: Silverlight Image Slider http://www.silverlightshow.net/items/Image-slider-control-in-Silverlight-1.1.aspx the other project is based on this: Open Video Player http://www.openvideoplayer.com/ I need to move the slider into the player, but the player uses a template and I just don't get how to merge the two as I do not understand resource dictionaries as they are applied to the player. We have completely gutted and made each proiject do what we want, but heck if I can figure out how to combine them.

  • WPF Datagrid -DataGridTemplateColumn tab focus issue

    I am using Microsoft WPF datagrid. I have noticed a strange behavior with WPF datagrid DataGridTemplateColumn. When you use the templateColumn in the grid and the template column contains some controls when you tab from the previous column the focus is not automatically given to the first element declared in the template column. The foucs is initally set on the border of the template column and when we tab of once agin the focus goes to the first column. Any workaround for this issue. How can i set the focus to go the first element in the template column of the datagrid when i tab off.

  • MPMoviePlayerController fullscreen quirk in iPad

    - by hgpc
    I want to show a MPMoviePlayerController in a view controller and let the user toggle full screen with the default controls, like the YouTube app. I'm using the following code in a bare-bones example: - (void)viewDidLoad { [super viewDidLoad]; self.player = [[MPMoviePlayerController alloc] init]; self.player.contentURL = theURL; self.player.view.frame = self.viewForMovie.bounds; self.player.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; [self.viewForMovie addSubview:player.view]; [self.player play]; } This works well until the user makes the video full screen, rotates the device and taps on the screen. The status bar is shown in the wrong position, as shown in the screenshot below. http://yfrog.com/5fimg0006ryp I'm working with the template Tab Bar Application for iPad. I've only added the viewDidLoad above, the view variables and an UIView in the XIB to show the movie player. What am I doing wrong?

  • DataTrigger to make WPF Button inactive until TextBox has value

    - by JohnB
    I want the Button control's property to be IsEnabled="False" until a value is entered into a TextBox in the Window. Code so far: <Button Content="Click Me" Name="ClickMe" VerticalAlignment="Top" Click="ClickMe_Click"> <Button.Style> <Style> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=textBox, Path=Length}" <!-- or even: Binding="{Binding Path=textBox.Length}" --> Value="0"> <Setter Property="Button.IsEnabled" Value="false" /> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Also, is it possible to have this Button control's IsEnabled property be based on 3 different TextBox controls all having values?

  • iPad/iPhone duplicate view and resize?

    - by MidnightLightning
    I'm working on an app that is similar to a Presentation application (Keynote/Powerpoint) for the iPad, that will use the VGA adapter to present on screen. However, if the presenter is using the external display for the presentation, I'm wondering if it's possible to have a miniature version of what's on the external display show up on the main iPad display (along with the presentation controls, which will take up most of the screen). In other words, I'm looking for a way with the iPhone SDK to "bake" the contents of a View (which will contain various Images and Labels in various locations) to an image (or some other static storage), resize it, and re-display it in another view. It would need to be smaller (since I don't want the 1024x768 external display to completely overlay the iPad's main display, only a corner of it), and either live-updating (literally an instance of the other View, just scaled), or be able to be refreshed, such that when updating the external display, the "picture in picture" version of itself would be updated too.

  • WPF MVVM: TextBox and default Button binding does update too late

    - by Sam
    I've got a simple WPF dialog with these two controls: <TextBox Text="{Binding MyText}"/> <Button Command="{Binding MyCommand}" IsDefault="True"/> Now, when I enter some text in the TextBox and click the button using the mouse, everything works like expected: the TextBox will set MyText and MyCommand is called. But when I enter some text and hit enter to "click" the default button, it does not work. Since on hitting enter the focus does not leave the TextBox, the binding will not be refresh MyText. So when MyCommand is called (which works), MyText will contain old data. How do I fix this in MVVM? In classic code-behind I probably just would call "MyButton.Focus()" in the MyCommand handler, but in MVVM the MyCommand handler does know nothing about the button. So what now`?

  • How can I set initial values when using Silverlight DataForm and .Net RIA Services DomainDataSource?

    - by TheDuke
    I'm experimenting with .Net RIA and Silverlight, I have a few of related entities; Client, Project and Job, a Client has many Projects, and a Project has many Jobs. In the Silverlight app, I'm uisng a DomainDataSource, and DataForm controls to perform the CRUD operations. When a Client is selected a list of projects appears, at which point the user can add a new project for that client. I'd like to be able to fill in the value for client automatically, but there doesn't seem to be any way to do that, while there is an AddingNewItem event on the DataForm control, it seems to fire before the DataForm has an instance of the new object and I'm not sure trawling through the ChangeSet from the DomainDataSource SubmittingChanges event is the best way to do this. I would of thought this would of been an obvious feature... anyone know the best way to achieve this functionality?

  • To get the parent node of a treeview in the TreeViewDragDropTarget in Silverlight

    - by Ramya
    Hi, I have created a TreeViewDragDropTarget like this, <controlsToolKit:TreeViewDragDropTarget msWindows:DragDrop.AllowDrop="False" ItemDroppedOnTarget="TreeViewDragDropTarget_ItemDroppedOnTarget" ItemDragCompleted="TreeViewDragDropTarget_ItemDragCompleted" AllowedSourceEffects="Copy"> <controlsToolKit:TreeViewDragDropTarget.Resources> <common:HierarchicalDataTemplate x:Key="hierarchicalTemplate" ItemsSource="{Binding ChildNode}"> <TextBlock Text="{Binding MainText, Mode=TwoWay}" TextWrapping="Wrap"/> </common:HierarchicalDataTemplate> </controlsToolKit:TreeViewDragDropTarget.Resources> <controls:TreeView x:Name="MainTreeView" BorderThickness="1" ItemTemplate="{StaticResource hierarchicalTemplate}" Background="Transparent" Cursor="Hand" BorderBrush="{x:Null}" VerticalAlignment="Top"/> </controlsToolKit:TreeViewDragDropTarget> All I am doing is dropping some text into the nodes of the treeview. I want to find the parent node of the drop target. How do I do it?

  • Enhance Localization performances? (ComponentResourceManager.ApplyResources)

    - by Srodriguez
    Dear all, After experiencing some performances issues on my client side, we decided to give a try to some of the performance profilers to try to find the bottleneck or identify the guilty parts of the code. Of course, as many performance investigations, the problems comes from various things, but something I find out is that the ComponentResourceManager.ApplyResources of my user controls takes way too much time in the construction of my forms: more than 24% of the construction time is spent in the ApplyResources inside the InitializeComponent(). This seems rather a lot for only "finding a resource string and putting it in it's container". What is exactly done in the ComponentResourceManager.ApplyResources ? I guess more than searching the string, if not it wouldn't take that long. Is there a way to enhance the performances of the localization? Our software is localized in several languages, so we do need to keep this multi-lingual feature. Any recommendations regarding this issue? Thanks! PS: We are coding in C#, .NET 3.5 SP1.

  • UserControl Focus Issue - Focus() sometimes returns false

    - by Craigger
    I have a user control that behaves similar to a tab control. The tab headers are UserControls that override Paint events to make them look custom. In order to leverage the Validating events on various controls on our tab pages, when the user clicks on the tab headers, we set the Focus to the TabHeader user control. I've noticed that Control.Focus() returns false sometimes but the documentation does not say why Control.Focus() will ever return false other than that the control can't receive focus. But I don't know why. Here's what i see. If my TabHeader UserControl does not contain any subcontrols, and I call myControl.Focus() from the MouseClick event, focus returns true. If my TabHeader UserControl contains a subcontrol, and I call myControl.Focus() from the MouseClick event, focus returns false. If my TabHeader UserControl contains a subcontrol, and I call myControl.subControl.Focus() from the myControl.MouseClick event, focus returns true. Can someone explain this?

  • What is the difference between NavigationService.Navigate() method and PhoneApplicationFrame.Source

    - by afriza
    Taken from Exercise 1: Creating Windows Phone Applications with Microsoft Visual Studio 2010 Express for Windows Phone Task 3: Step 9 // navigate this.NavigationService.Navigate(new Uri("/PuzzlePage.xaml", UriKind.Relative)); Note: The PhoneApplicationPage class provides methods and properties to navigate to pages through its NavigationService property. You can call the Navigate method of the NavigationService and pass the URI for the page as a parameter. You can also use the GoBack and GoForward methods to navigate backward or forward in the navigation history. The hardware back button also provides backward navigation within an application. The event handler shown above uses the NavigationService to go to the PuzzlePage.xaml page. Task 4: Step 3 (RootVisual as Microsoft.Phone.Controls.PhoneApplicationFrame).Source = new Uri("/ErrorPage.xaml", UriKind.Relative); Note: ... Whenever you set the Source property to a value that is different from the displayed content, the frame navigates to the new content. ... What are the differences and similarities of both techniques?

  • JSF 2 equivalent of tomahawk subform

    - by digitaljoel
    I have an existing JSF 1.2 app that was a portlet running on glassfish v2. I'm converting it to a webapp running on glassfish v3. The app uses tomahawk subforms in several areas. Tomahawk has not been update for JSF 2, which is what ships with glassfish v3. We would like to update our app to JSF 2. Is there a JSF 2 equivalent to tomahawk's subform? I know one option would be to change all of the subforms to be ajax enabled and use the execute attribute to specify which controls take part in the form submission, but would like to make this as straight across as I can without modifying existing functionality if I can. So, lacking a tomahawk subform substitute, is there any way to specify partial form submission for non ajax events?

  • WPF DataGrid RowDataBound?

    - by SiN
    Ok this is driving me mad, I feel like a total Newbie. I'm using WPF's DataGrid control from Dynamic Data Display with .NET 3.5. Link on Codeplex here I want an equivalent to the classic GridView's RowDataBound event, and I can't find any. I tried working with LoadingRow, but it fires every time I scroll. I'm trying to change the background color of certain cells in my grid based on a database values. I'm new to WPF. Should I be using the XAML binding?

  • ItemsControl.ItemsSource MVVM performance

    - by bitbonk
    I have an (non-virtualized) ItemsControl that binds its ItemsSource to a ObeservableCollection of ViewModel instances. Now once the large amount Model instances is loaded all the ViewModel complemnents needs to be added to that ObservableCollection. How can I add a large amount of ViewModels without making the UI Thread hang? I suppose the UI Thread hangs because each time a new item is added the ItemsControl needs to update itself and does layout etc. over and over again. Should I suspend the binding add all items and then resume? If so, how? Should I override the ObservableCollection to implement an AddRange so only 1 CollectionChanged Event is fired for adding multiple items? Or alternatively just replace the whole collection? Or is it better to add each items separately and call Dispatcher.Invoke for each item separately? So I would unblock frequently. How do you handle large dynamic lists that can not be virtualized?

  • 'Please wait' screen between pages in C# ASP.NET. Best practice?

    - by Glinkot
    Hi, I have a gridview with some imagebuttons, each of which kicks off a report page for that item. The report take 10-15 seconds to run, so I'd like a popup 'Generating report, please wait' type thing. I can think of a few ways but would like the opinion of those more experienced than I. The options I was considering: a) link my imagebutton to an intermediate page that says 'please wait', and then refer it onto the report page from there. Seems a bit clunky b) Investigate using jquery or similar. I have telerik controls, they have a few things but it isn't clear if any are suitable. c) Define some kind of CSS layer with a please wait warning on it, and make it visible as part of the button's onclick event d) Look into jquery or similar Any thoughts? Thanks!

  • Segmented Control to change views

    - by Goods
    I have created an up/down arrow segmented control button on the right side of the navigation bar in my detail view. In a table based application, how can I use these up/down arrows to move through cells in the parent table? The apple "NavBar" sample code has an example of this but the controls are not functional. The iBird program has this functionality as well and it is very nice. Download the "iBird 15" program for free. Any thoughts? Thanks!

  • How can I extend DynamicQuery.cs to implement a .Single method?

    I need to write some dynamic queries for a project I'm working on. I'm finding out that a significant amount of time is being spent by my program on the Count and First methods, so I started to change to .Single, only to find out that there is no such method. The code below was my first attempt at creating one (mostly copied from the Where method), but it's not working. Help? public static object Single(this IQueryable source, string predicate, params object[] values) { if (source == null) throw new ArgumentNullException("source"); if (predicate == null) throw new ArgumentNullException("predicate"); LambdaExpression lambda = DynamicExpression.ParseLambda(source.ElementType, typeof(bool), predicate, values); return source.Provider.CreateQuery( Expression.Call( typeof(Queryable), "Single", new Type[] { source.ElementType }, source.Expression, Expression.Quote(lambda))); }

  • Choosing Between Prism and Caliburn

    - by Innogetics
    I have been using Prism 2.0 for a personal project for a few months now. I have recently heard of Caliburn and am wondering if there are compelling reasons for me to consider that instead. I like Prism's dynamic module loading capability. I intend to build modules for my application and would like to be able to deploy them in a modular manner. Is that also possible with Caliburn? What are the advantages of Caliburn over Prism? (I read that Prism will also have a new version by September 2010 that will leverage .Net 4.0. and am keeping my application flexible to be updated by then as well.)
