How to capture the screen in a Metro C# app

阅读更多关于 How to capture the screen in a Metro C# app

问题 Anyone got a snip for grabbing a screenshot of your metro app using C#? Or C++? Or VB? Thanks... 回答1: No, there is no way for a Metro style app to do this. By design they cannot directly interact with other apps outside of themselves, including capturing screenshots which may include other apps. There also isn't a way for a Metro style app to render Xaml elements to a bitmap so you can't readily implement this for your own app. --Rob More details are found here : MSDN Forum I haven't test

How does the WinRT Chrome app print without triggering the OS's “Print” dialog?

阅读更多关于 How does the WinRT Chrome app print without triggering the OS's “Print” dialog?

问题 How does the WinRT Chrome app print without triggering the OS's "Print" dialog? From what I've seen elsewhere, every WinRT app must go through the Windows Print dialog to print. But when you print a page from the Chrome Metro app, you get the Chrome Print dialog, and the Windows Print dialog is not triggered. 回答1: I don't think you can. The one browser app that enjoys the privilege of being your WinRT browser also enjoys special privileges not granted to other WinRT apps. For example, you can

Surface SDK only for surface

阅读更多关于 Surface SDK only for surface

This might be a stupid question, but I couldn't find the answer anywhere. Does the Microsoft Surface SDK 2.0 only work with Microsoft Surface products, or can I use it with other touchscreens? I really just like the way the SurfaceTextBox control works (popping up a onscreen keyboard when clicked) and was wondering if I could use it in a program I'm making (which uses a Elo touchscreen monitor, not multi-touch). Edit Thanks for the responses. I downloaded and installed the SDK 2.0 and tried to run the sample apps that are included. They don't seem to respond to my finger touches but do work if

Metro App, Query Current Apps in Windows Store

阅读更多关于 Metro App, Query Current Apps in Windows Store

问题 How does one query data such as App Icons, Reviews, Stars, Price, etc. from Windows Store in another App? For instance, picture an app called "best drawing tools" with comparisons of 5 popular drawing tool apps, then links to Window Store (Or even better direct install links). The premise of the app "Great Windows Apps" (http://www.greatwindowsapps.com) seems to be the basic functionality I am trying to imitate. I also found MetroStore Scanner http://metrostore.preweb.sk which appears to

问题 When I try to run .NET 3.5 applications on Windows 8.1 which has not .NET 3.5 Framework, Windows will show the "An app on your PC needs the following Windows feature. .NET Framework 3.5 (includes .NET 2.0 and .NET 3.0)" dialog automatically.
