  • Non laggy movement in Flex or WPF

    - by PaN1C_Showt1Me
    I'm trying to learn something about 2D games programming. For this purpose I've downloaded many samples developed in: Flex and Microsoft WPF. I've noticed that all the animations / moving objects are kind of non-smooth. I've seen a Flex example with double buffering which solved the image flickering, but it was laggy too. WPF example too. Just to mentioned, all examples were drawing on Canvas. I'm just curious, is it possible to have a wonderful non-laggy movement on the GUI in Flash or WPF ? (e.g. like a real game, coded in C++)

  • How to make WPF app work as a child process in Citrix

    - by RichardOD
    I am working on a 3rd party application that allows plugins to be written in .NET 1.1. I have decided I would like to write my plugin in a seperate process that is called from the .NET 1.1 application (achieved using Process.Start). This is fine- I create a new process that is a WPF app. When I launch this through MSTSC everything works as expected, however when I run the app through Citrix, the WPF child app fails to render correctly, and the mouse position starts going crazy- the child process window is basically not usable. Is there a way to avoid this happening? If I create a seperate WPF application and deploy this through Citrix everything works fine. If I create a child Windows forms app in .NET 3.5, that also works fine.

  • WPF: Hidden parent and visible child

    - by oakskc
    As of last night, I decided to start learning about WPF and have been reading through a number of online tutorials and books. This is a huge shift. One feature that has fascinated me is the implicit property value inheritance. I know in the WinForms world, if a control is not visible then neither are any of the child controls. Same seems to be true in the WPF world, as expected. I wondered if explicitly setting the child control's Visibility property would allow for an invisible parent and visible child and it did not. Is this something that would be possible in WPF? Can you have a container control that is hidden with visible children? This is more an exercise of curiosity than anything. I'm still trying to wrap my head around a lot of what I've been reading.

  • What are the advantages of combination WPF + XNA?

    - by MartyIX
    Hi, I'm porting my application from Winforms+XNA to WPF (+ XNA?) and I would like to know if the combination WPF + XNA makes sense or not. If it brings some advantages or if it is rather a bad choice. A few points about my game: It's a desk game with simple 2D animations (movement) Main window contains panels like available games/players etc. + console. I would like to add some fancy scenes to my program (at end of game, ...) http://www.codeproject.com/KB/WPF/XnaInWPF.aspx is the code I would like my program base on. So the appearance is quite similar to a chess program. Thank you for suggestions!

  • Pin WPF window on the desktop in Windows 7

    - by Dennis1001
    I want to pin a WPF window on the desktop (it should be a desktop gadget). I know you can do this by setting the parent handle of the WPF window to the handle of the "progman" window. But this does not prevent the hiding of the WPF window when "Windows + D" is pressed. There must be another way do to this. The new desktop gadgets in Windows 7 are not hidden when "Windows + D" is pressed. How did the MS developers achieve this?

  • Would you go by WPF or WinForms? [on hold]

    - by Lorem Ipsum
    Consider the following project facts/requirements: Desktop app with try icon and notification system Forms over data Quick response needed Internal app in big corporation planned to be hosted on Windows Vista, later maybe Windows 8.x Operating system slowed down by many group policies (frequently changing GPO) No special graphic requirements So, would you go by WPF or WinForms? Edit: Please bear in mind the facts/requirements I mentioned above. The application will run on corporate machines which are very slow and without really good graphical acceleration. The crucial is to have really quick response and start time.

  • In WPF, should I base my converters on types or use-cases?

    - by user1013159
    I'm looking for some advice on how to write my WPF value converters. The way I'm currently writing them, they are very specific, like (bool?,bool) = Brush, i.e. I'm writing each converter for a specific use case, in this case, the Brush is bound to an indicator showing equality information between the bool? and the bool. This obviously makes re-use very hard and I end up with a quite large list of converters. Should I strive to write my converters in a more general way? Can I?

  • using one data template in another data template in WPF

    - by Sowmya

Could anyone please suggest if would this be a right approach, if so how can I acheive that? Thanks in advance, Sowmya

  • Get the 'actual font' being used for a WPF element

    - by mackenir
    WPF lets you specify the FontFamily of TextBlocks, Buttons, etc. Is there a way to discover what font WPF decided to use for a given element? For example, if you leave the FontFamily unspecified, styles notwithstanding, an element will take on the Font Family 'GlobalUserInterface'. In this case, can I determine programmatically what font is actually being used to render an element's text?

  • How to hide close button in wpf window?

    - by Michael Hedgpeth
    I'm writing a modal dialog in wpf. How do I set a wpf window to not have a close button? I'd still like for its WindowState to have a normal title bar. I found ResizeMode, WindowState, and WindowStyle, but none of those properties allow me to hide the close button but show the title bar, as in modal dialogs.
