  • wpf Image resources and visual studio 2010 resource editor

    - by Berryl
    Hello My motivation for this question is really just to specify an image to be used in a user control via a dependency property for ImageSource. I'm hitting some pain points involving the management, access, and unit testing for this. Is the resource editor a good tool to use to maintain images for the application? What is the best way to translate the Bitmap from the editor to an ImageSource? How can I grab the resource Filename from the editor? Cheers, Berryl

  • How to resize controls at runtime in java

    - by user1349213
    Is there a way to resize a control, a JTextfield for example, at runtime in java? I want my textfield to have the resize cursors (just like when you point your cursor on the corner of a window) and will be able to resize on runtime. Ive read on the internet that vb6 and C# have those capabilities, is there anything for java? A sample code or a link to a good tutorial will be very much appreciated. Thank you.

  • How to Update TreeViewItem's IsExpanded property to false in code behind?

    - by viky
    I am working with WPF TreeView control. I am creating a hierarchical data structure and assigning it to ItemsSource and it will generate TreeviewItems automatically. By default I use IsExpanded of TreeViewItem to true. But in a particular case, I want to set IsExpanded property to false. So that treeview loading doesn't take time to generate all items. How can I set that in code since I don't have reference to TreeViewItem's instance at that time?

  • Vertical scrolling in silverlight

    - by Mrt
    I have a silverlight application that is set to use 100% browser height. As I dynamically add controls to a canvas (which can be dragged around), I would like the expand the canvas vertically. Ideally show the browser scrollbar so the user can move up or down, if that can't be done, use the scrollbar control. I would also need to handle the user changing the size of the browser. Any suggestions on how to do this ? Cheers,

  • C++ MIDI file reading library

    - by Raceimaztion
    I'm trying to write some software to read a MIDI file into an internal data format and use it to control 3D simulated instruments. My biggest problem is reading the MIDI data in from a file, and I'd like to avoid writing all the import code. Does anyone know of a free (preferably Open Source), cross-platform MIDI file reading library? What features does it have? Can it import other note-based music formats?

  • Is there a good .Net CSS aggregator that combines style sheets and minifies them?

    - by vfilby
    I am looking to see if there is an open source/free project that provides a CSS manager. I am looking for this mainly for performance tweaking and hoping there is a readymade project rather than building from scratch. Features I am looking for include: Combines multiple .css files into a single css file Optionally minifies the resulting .css file Works well with .Net (a user control, custom handler, etc) Is there a project out that that handles this?

  • WPF MediaElement video playback tearing

    - by GeekyMonkey
    I'm trying to use the MediaElement control in WPF to play back video. It works great in Vista, but when I run it on an XP machine I get tearing in the display. It looks as if it's not using the vertical synch, and just updating the screen mid-draw. Anyone know how to fix this problem?

  • Tooltip steals mouse click

    - by deerchao
    I'm writing a custom TreeView from ScrollableControl. I decided to show tooltips when the mouse hovers over nodes with text too long to display. I find that when tooltips are shown, the user is not able to click the node to select it because (I think) he's clicking the tooltip window, not my control. Is there any easy solutions? As far I can see, System.Windows.Forms.TreeView don't have this problem. Thanks!

  • Disable animations when ending search in iPhone

    - by camilo
    Hi. A quicky: is there a way to dismiss the keyboard and the searchDisplayController without animation? I was able to do it when the user presses "Cancel", but when the user presses the black "window thingy" above search field (only visible while the user hasn't inserted any text), the animation always occurs, even when I change the delegate functions. Is there a way to control this, or as an alternative, to disable the user to end searching by pressing the black window? Thanks in advance.
