WinRT image handling

问题 A friend and I spent the better part of last night nearly tearing our hair out trying to work with some images in a metro app. We got images into the app with the share charm, and then I wanted to do some other work with them, cropping the images and saving them back into the appdata folder. This proved extremely frustrating. My question, at the end of all this, is going to be "What's the proper way of doing this, without feeling like I'm hammering together a bunch of mismatched jigsaw puzzle

Is there a way to find the PackageFamilyName at runtime?

阅读更多关于 Is there a way to find the PackageFamilyName at runtime?

Is there a way to figure out the PackageFamilyName (as appearing in the manifest) in runtime? I looked in /Program Files/WindowsApps and could not find the relevant string there. Could not find any API that would let me do this... Any other ideas are welcome. I think what you're looking for is PackageId.FamilyName which is available through the Package.Current.Id.FamilyName property.

阅读更多关于 Color of startscreen in Windows 8 through Metro DynamicResource?

I've looked through Generic.xaml and ThemeResources.xaml in the following path: C:\Program Files (x86)\Windows Kits\8.0\Include\WinRT\Xaml\Design However, they don't seem to contain a resource key that I can use in order to retrieve the color of the current scheme selected in the Windows 8 start screen. The color I am trying to retrieve through a DynamicResource in the XAML is seen visually below, to demonstrate my point. There is no API available to use the currently selected Windows theme color. Yes, no API unluckily. What about this workaround? http://blog.quppa.net/2013/01/02/retrieving

How to remove ListView's add item animation?

阅读更多关于 How to remove ListView's add item animation?

问题 I have a ListView and I edited its ItemContainerStyle to modify some style but I don't know how to remove that annoying animation when you add an item. With an ItemsControl , when you add a new item, it appears instantly, without any animation. With ListView , the item takes a while and then, it starts an animation to show up. I just want to remove that add animation and when I click on Add item it appears instantly, no extra stuff. I think that it should belong to ItemContainerStyle but even
