  • How can i change background image of a button when hover or click in XAML for Windows 8?

    - by apero
    I got a question about changing the background image of a button when it's clicked. I tried searching on google but i couldn't find something that worked for me. Well here's my code <Button Grid.Column="0" Grid.Row="0" x:Name="btnHome" VerticalAlignment="Stretch" BorderBrush="{x:Null}" HorizontalAlignment="Stretch" Click="btnHome_Click" PointerEntered="btnHome_PointerEntered"> <Button.Template> <ControlTemplate TargetType="Button"> <Border x:Name="RootElement"> <VisualStateManager.VisualStateGroups> <VisualStateGroup x:Name="CommonStates"> <VisualState x:Name="MouseOver"> <Storyboard> //I want my background change here </Storyboard> </VisualState> <VisualState x:Name="Pressed"> <Storyboard> //And here </Storyboard> </VisualState> </VisualStateGroup> </VisualStateManager.VisualStateGroups> <Border.Background> <ImageBrush ImageSource="images/back_button.png"/> </Border.Background> </Border> </ControlTemplate> </Button.Template> </Button> i also tried this private void btnHome_PointerEntered(object sender, PointerRoutedEventArgs e) { BitmapImage bmp = new BitmapImage(); Uri u = new Uri("ms-appx:images/back_button_mouseover.png", UriKind.RelativeOrAbsolute); bmp.UriSource = u; ImageBrush i = new ImageBrush(); i.ImageSource = bmp; btnHome.Background = i; } But unfortunately this worked neither

  • Can you make a living as a system programmer?

    - by Helper Method
    Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?

  • how do you load files in windows phone 7?

    - by matt
    do you seriously have to make your own content pipeline project for every single type of file you want to load? Microsoft just seem to be pretending that the iphone doesn't exist (even though they are now paying devs to port between them). I'm trying to port my game from the iphone to winmo7, and I already have a nice asset pipeline set up for exporting textures in the exact format we want (16 bit fmts ect) I just want to be able to open a file and read it, just like I would on any other platform. I have tried System.IO.File.OpenText("atextfile.txt"), but it says that function is "RESTRICTED!!!!" I have tried just adding the txt file to the content project, setting its properties to "content" and "copy always" and then trying to open it doing this.Content.Load("atextfile.txt"); with and without the extension, says it can't find the file.

  • Which term to use when referring to functional data structures: persistent or immutable?

    - by Bob
    In the context of functional programming which is the correct term to use: persistent or immutable? When I Google "immutable data structures" I get a Wikipedia link to an article on "Persistent data structure" which even goes on to say: such data structures are effectively immutable Which further confuses things for me. Do functional programs rely on persistent data structures or immutable data structures? Or are they always the same thing?

  • Post bacc CS certificate of Java Certification?

    - by gwozdz
    I have a BS in biology, MS in Environmental Science, but I've been writing software in C++ and Java throughout grad school and a bit in my current job. I'd love to transition to a programming career. I've thought about getting what's called a "Post baccalaureate Certificate" or Java certification in lieu of another degree in CS. Which is more useful in terms of getting a job?

  • Windows Mobile 6.x How to explicitly lock the app in one orientation?

    - by Stuart
    I'm trying to get an app on the WinMo App Store. As part of this, Microsoft App's Store has asked that I need to support landscape as well as portrait. What they've said is OK is: If dynamic switching is implicitly allowed, the app will be tested just as if it supports both portrait and landscape even if only a portrait or landscape resolution is checked. You may explicitly lock the app in one orientation (which means portrait mode if the app does not handle landscape mode functions), provided the default OS orientation is preserved once the app exits. I'd love to do answer 2 - but I can't find any way of doing it - and they won't provide me any other clues - they suggested I ask on the forums... so here I am on Stack Overflow - far better than on the forums :) Anyone got any suggestions?

  • Virtualization of Legacy API and co-existence with more modern API?

    - by Pharaun
    I don't mean for this question to be a flame bait but I'll be using Microsoft and their win32 API as a example of a legacy API. Now what I am wondering here is Microsoft is spending a lots of their money and energy in maintaining their legacy API, including all of the "glitches/bugs/workaround" that are needed to keep the API functioning the same. Now I'm aware that in Windows 7 they are providing a way for the customer to run their application in a "Windows XP" VM which would be one such way for them to start cleaning up their win32 API because they could then push all of the application into the "Windows XP" VM. So now what I am wondering is, is it possible to virtualization a legacy API in such way that an customer/program can still access and use it, yet at the same time be able to take advantage of the newer version/API? Because as far as I understand it, if the application is ran in the "Windows XP" VM, it won't be able to access any of the newer API/feature of Windows 7.

  • How can I navigate through xaml pages with Monogame in a Windows Phone 8 project?

    - by misiMe
    I finished to develop an XNA game, then I created the Monogame project, and tested it on my device. Now I made some other pages such as an "about" page. How can I go to that page considering I have a Monogame project and just an XNA code? In particular inside my game I made a Main Menu where you can click the "about" button and know if someone has clicked: how can I link that event to the "go to about.xaml" function? Inside XNA, update method: if (about_button.IsClicked()) { // Go to about.xaml } I tried: if (about_button.IsClicked()) { ((PhoneApplicationFrame)Application.Current.RootVisual).Navigate(new Uri("/About.xaml", UriKind.Relative)); } But it throws: System.UnauthorizedAccessException

  • How can I test a windows dll to determine if it is 32bit or 64bit?

    - by morechilli
    I'd like to write a test script or program that asserts that all dlls in a given directory are of a particular build type. I would use this as a sanity check at the end of a build process on an sdk to make sure that the 64bit version hasn't somehow got some 32bit dlls in it and vice versa. Is there an easy way to look at a dll file and determine its type? The solution should work on both xp32 and xp64.

  • Lambda functions

    - by Oden
    Hey, I'm really interested in the way of using lambda functions. Does it make sense to use them in a high-level programming language? If yes, why? Is this really just a function embedded in a function (like this) or is there more behind?

  • How do I get the "bucket id" that winqual uses if I have a minidump file or exception structure? (Windows c++)

    - by Tim
    There are a few related questions on SO - but have not found the answer - I would like to generate a "signature"/bucket id to report a minidump/crash back to our issue tracking system. Since MS already does this with "bucket ids" I figured I could just re-use their bucket/signature generation. Can I get that ID from either a top level filter or the _EXCEPTION_POINTERS object I have inside the filter or the _MINIDUMP_EXCEPTION_INFORMATION structure or from the minidump itself? This is a C++ application.
