问题 It seems that my problem may be the same as an unanswered related question (OpenGL with GLUT on windows 7, fullscreen mode not showing the message box). Since I switched to Win7 as a development environment, and a possible target platform for my applications, I noticed a regression in their behaviour. Whenever I have a fullscreen window containing a fullscreen OpenGL context, the applications have problems displaying modal dialog boxes (such as message boxes, file open dialog, etc.) The

问题 I am developing a paint like application. I want to change cursor at some instance. So, how can I use the custom cursor in metro app ? I have found this Window.Current.CoreWindow.PointerCursor = new Windows.UI.Core.CoreCursor(Windows.UI.Core.CoreCursorType.Custom, uint id); In above method, there is one enum for "Custom" cursor and the second argument is for resource ID. So how can I get that ? 回答1: The basic route to doing this: Create your custom cursor and package it in a .res using a C++

问题 Currently I am developing application for the Windows Store which does real time-image processing using Direct2D. It must support various sizes of images. The first problem I have faced is how to handle the situations when the image is larger than the maximum supported texture size. After some research and documentation reading I found the VirtualSurfaceImageSource as a solution. The idea was to load the image as IWICBitmap then to create render target with CreateWICBitmapRenderTarget (which

问题 I have a page with a vertical set of textboxes. If one of them is focused, all of them should be visible, even if the onscreen keyboard is displayed. There are just enough of them that all of them fit in the available space above the keyboard. When the bottom textbox is focused, the page gets automatically scrolled up so that all of them are visible, but if the top textbox is focused, the onscreen keyboard covers the bottom one. This is a simplified example of my page: <Grid Background="

问题 I want to play sound from a mp3 file in windows 8 metro-style app. I tried two approaches to do so: Method1: This is using the code provided by https://stackoverflow.com/a/10961201/147530. It works. Method 2: Here I just new a MediaElement and set its Source property like so: var x = new MediaElement { Source = new Uri("ms-appx:/Assets/MyMp3File.mp3") }; When I do x.Play() nothing happens however. There are no exceptions thrown. Question: How can I make method 2 work? EDIT: Wanted to update

问题 I have a web application. I my JavaScript, I am identifying devices by user agent string as follows: _android = navigator.userAgent.toLowerCase().indexOf("android"); _iOS = navigator.platform.indexOf("iPhone"); My task is to identify if device is win8 tablet or not?

问题 I am developing a Windows 8 Metro app, and we intend to deploy it to only a few tablets within our company. It's not meant for the Windows Store. We need the app to access some directories on the company's network share, but forcing the user to use a FilePicker isn't what we want. Our first attempt was to use await StorageFolder.GetFolderFromPathAsync("J:\\"); . This didn't work, and produced the following exception: An unhandled exception of type 'System.UnauthorizedAccessException' occurred

问题 How do you disable the selection single item from a GridView? I have a GridView with it's ItemsSource bound to an IEnumerable<SampleDataItem>. I'd like to be able to programmatically not allow the selection of some items in the list while allowing selection of the others. 回答1: While I haven't done this, you should be able to use an ItemContainerStyleSelector on the GridView, the method gives you the container (GridViewItem) and the item you're binding to. From there you can set the IsEnabled
