由 感情迁移 提交于 2019-12-06 04:37:49
I have a ordinary .net 4 WPF application which is supposed to be run on a Windows 8.1 tablet. From this application I would like to start the native Metro camera app, if it is available. I´ve tried looking for answers, but it seems to require a Windows app to start metro apps. So is it even possible? Thank you :) Have a look at this article: http://winaero.com/blog/exclusive-how-to-start-a-modern-app-from-desktop-without-going-to-the-metro-start-screen/ Basically, you need to run: explorer shell:AppsFolder\Microsoft.MoCamera_cw5n1h2txyewy!Microsoft.Camera e.g. Use: Process.Start("explorer", @

Detecting a scroll event in GridView (Windows 8)

由 孤者浪人 提交于 2019-12-06 03:25:50
How do we detect a scrolling event in GridView (like ViewChanged on ScrollViewer) on somethig like the default GridView template sample app? I'd like to replicate the effect that the netflix App does on the left red strip. I tried putting the GridView inside a scrollviewer, but I've been unsuccessful at stretching it to fill the screen for different resolutions. Update: I intend to use this with VariableGrid control that's on NuGet - though it's not an official control, it inherits GridView The best way to do this seems that you can read through the components of the control, and assign events

Is this the only reliable way to obtain the list? Does anyone know of any other ways? Thanks in advance 回答1: I wish I could comment...Is this an option?

How to append array of bytes to the existed StorageFile?

由 喜你入骨 提交于 2019-12-06 01:49:13
问题 I need to write to a file data by chunks of bytes consequentially (in my Metro app) and there is a class FileIO with methods AppendTextAsync and WriteBytesAsync but without needed AppendBytesAsync so how can I append an array of bytes to a StorageFile ? 回答1: This code seems to work for me: String s = "hello"; Byte[] bytes = Encoding.UTF8.GetBytes(s); using (Stream f = await ApplicationData.Current.LocalFolder.OpenStreamForWriteAsync ("hello.txt", CreationCollisionOption.OpenIfExists)) { f

I have calls to Grid.SetRow and Grid.SetColumn in my code which I'm trying to animate. According to the answer at http://social.msdn.microsoft.com/Forums/en-CA/wpf/thread/257779f7-b459-43fc-a4a1-f24641c50e09 , it is recommended to make use of FluidMoveBehavior, but it doesn't look like this is available for Windows 8. What are my options for animating the children of a Grid when their positions change? I'm basically looking for a way to achieve linear transition. There is a new built-in feature called Transitions that can be used, here is an intro . Try adding a RepositionThemeTransition to

How to give a “Empty ListView Message” when there is no data source

由 只愿长相守 提交于 2019-12-06 01:23:13
问题 My application have a ListView with GridLayout. I am now trying to introduce ListView groups into my application. Say, the data source would usually have Group1, Group2 and Group3. I would like to display all 3 groups all the time regardless there is element in it or not. When there is no element in a group, I want to display a "empty group" message under the group title. I think the default way that WinRT handles it is not to display the empty group and it makes a lot of sense in many
