  • Composite operations in Android Canvas

    - by kayahr
    I'm just starting with Android development and I'm coming from JavaScript/HTML world so I'm currently investigating the possibilities of the Android SDK. The HTML 5 canvas supports composite operations (See here). Is this possible in an Android Canvas? I scanned the API of the Canvas class but couldn't find anything useful. I need at least the composite operation "source-in" or (if this isn't possible) "source-atop".

  • How can i trace changes made to the DOM by JavaScript?

    - by Denis Hoctor
    I have a large website in development with a large amount of JS in different files. I have come across an issue where something is removing a class from the DOM. I can see it when I view source but not in Firebug. Normally I would place some alerts/console.log calls with the hasClass value but because I have no idea where to start I wanted to know if I can trace the change back when it occurs somehow? Denis

  • Java REPL shell

    - by Don
    Hi, I'm looking for a REPL shell that I can use to test out snippets of Java code. Either a desktop app, or a web app (like the Groovy web console). Ideally, commonly used Java packages like: java.io.* java.util.* should be automatically imported, so that I can copy and paste code from a class without having to add a bunch of imports. Does such a thing exist? Thanks, Donal

  • Create an Xml file from an object

    - by remi bourgarel
    I work as a web developer with a web designer and we usually do like this : - I create the system , I generate some Xml files - the designer display the xml files with xslt Nothing new. My problem is that I use Xml Serialization to create my xml files, but I never use Deserialization. So I'd like to know if there is a way to avoid fix like these : empty setter for my property empty parameter-less constructor implement IXmlSerializable and throw "notimplementedexception" on deserialization do a copy of the class with public fields

  • Hosting Microsoft Office application inside Silverlight 4?

    - by Ivan Zlatanov
    I know that Silverlight 4 has the support for COM interop via the AutomationFactory class. dynamic excel = AutomationFactory.CreateObject( "Excel.Application" ); excel.Visible = true; Easy. But this creates a separate process for the COM object. What I am missing here is if I am actually able to actually host the office document inside my silverlight application - in a ContentPresenter for example? Thanks in advance.

  • Can't override a global WPF style that is set by TargetType on a single specific control

    - by Matt H.
    I have a style applied to all my textboxes, defined in a resource dictionary.. <Style TargetType="TextBlock"> <Setter Property="TextBlock.FontSize" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontSize, Mode=OneWay}" /> <Setter Property="TextBlock.TextWrapping" Value="Wrap" /> <Setter Property="TextBlock.VerticalAlignment" Value="Center"/> <Setter Property="Background" Value="Transparent"/> <Setter Property="TextBox.FontFamily" Value="{Binding Source={StaticResource ApplicationUserSettings}, Path=fontName, Mode=OneWay}"/> </Style>\ The fontsize and fontstyle properties are bound to a special user settings class that implements iNotifyPropertyChanged, which allows changes to font size and fontfamily to immediately propogate throughout my application. However, in a UserControl I've created (Ironically, the screen that allows the user to customize their font settings), I want the font size and fontfamily to remain static. No matter what I try, my global font settings override what I set in my user control: <UserControl x:Class="ctlUserSettings" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:R2D2" Height="400" Width="600"> <Grid> <Grid.Resources> <Style x:Key="tbxStyle" TargetType="TextBox"> <Style.Setters> <Setter Property="FontSize" Value="14"/> <Setter Property="FontFamily" Value="Tahoma"/> </Style.Setters> </Style> ... etc... <StackPanel Margin="139,122.943,41,0" Orientation="Horizontal" Height="33" VerticalAlignment="Top"> <TextBox Style="{x:Null}" FontSize="13" FontFamily="Tahoma" HorizontalAlignment="Left" MaxWidth="500" MinWidth="350" Name="txtReaderPath" Height="Auto" VerticalAlignment="Top" /> <TextBox Style="{x:tbxStyle}" Margin="15,0,0,0" HorizontalAlignment="Left" Name="txtPath" Width="43" Height="23" VerticalAlignment="Top">(some text)</Button> </StackPanel> I've tried setting Style to {x:Null}, setting custom font sizes inline, and setting a style in the resources of this control. None take precedence over the styles in my resource dictionary. As you can see, I show a sprinkling of all the things I've tried in the XAML sample above... What am I missing?

  • Heterogeneous NSTreeController

    - by andyvn22
    I have an NSTreeController (supplying content to an NSOutlineView). I'd like the top-level objects to be of one class, and all other objects (so, children at any level) to be of another. What's the best way to go about this? I'll need to somehow change the behavior of at least add, addChild, insert, and insertChild, I suppose. I was hoping, though, to find a simple way to account for this in only one location, rather than changing four separate methods.

  • XML deserializer (Iserialzable)

    - by user311130
    Hey everybody, I have a class in c# that implements Iserialzable. I'm using a XMLSerializer that produces a XML from instance of that class. I get the following XML: <?xml version="1.0"?> <Configuration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <SessionConfiguration> <RemoteMachineName>HV-BENDA</RemoteMachineName> </SessionConfiguration> <SessionsCredentialsList> <CredentialsItem> <User>test0</User> <Password>Pa$$word1</Password> </CredentialsItem> <CredentialsItem> <User>test1</User> <Password>Pa$$word1</Password> </CredentialsItem> <CredentialsItem> <User>test2</User> <Password>Pa$$word1</Password> </CredentialsItem> <CredentialsItem> <User>test3</User> <Password>Pa$$word1</Password> </CredentialsItem> <CredentialsItem> <User>test4</User> <Password>Pa$$word1</Password> </CredentialsItem> </SessionsCredentialsList> <TIME_OUT /> <LOCAL_USERS_NUM>5</LOCAL_USERS_NUM> </Configuration> At some later point in the code I use a XMLSerializer again to deserial that XML document. and I get the following error: {"There is an error in XML document (1, 1)."} Inner exception: {"Data at the root level is invalid. Line 1, position 1."} Do someone knows wat could be the problem? All the best
