问题 I made a very small application that captures the screen inside games using SlimDX.

This may cause application crashes, corruption and data loss. When passing delegates to unmanaged code, they must be

问题 This question already has answers here : Screen Capture in android (4 answers) Closed 4 years ago . How can I programmatically perform a screen capture on an Android phone? 回答1: You cannot do this from an android app except on a rooted phone, as you don't have permission to access the framebuffer device.

To test this, I created a series of scheduled tasks to launch the app, take a screenshot, and then close the app. These tasks are all run through .bat files. Everything works fine except for the screenshots. When run as a scheduled task, the .jpg from the screen capture always shows a black box. If I execute the .bat file normally, the screenshot looks fine. I am using nircmd to

问题 I am using VSTS 2008 + .Net 3.5 + C# + Microsoft Expression 3 SDK. I want to capture screen and output a wmv file. I tried hard but can not found C# samples from Google. Any reference samples? 回答1: Wrong kind of tool, Expression Encoder is a transcoder. It requires a video format as input and encodes it to a different output format.
