问题 How do I show a image from a PNG, BITMAP, JPEG file, ect. on the screen without a window? I want the image to appear with no frame surrounding it preferably without it registering on the task bar as a window. I would like to put these images on the screen in rapid succession.

Thanks! 回答1: This will create a shaped window with transparent

问题 I am trying to implement a Splash Screen using this java and xml code. I created a separate java class from my main activity and placed the java code inside. I created an xml layout in my layout file and placed the xml code inside. However, my app appears normally without a splash screen. It never shows, but the app does not have any errors.

问题 I have designed an application using the Tkinter module from Python, on my 17" screen. Is there a way to make this app fit on lower resolution screens?

No luck however - sometimes it works, sometimes not. The broadcast is asynchronous with the

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago . I found this post that suggests to use AirServer to capture video from iPhone. Unfortunately AirServer doesn't support iPods (even though I have a 4th gen iPod running iOS 5.0). Is there a way via software or should I get my iPod to connect to a TV and record it there? I have seen that there are some good cables

问题 Is it easy to write some .Net code to record screen and audio (from computer mic), then output to an wmv file. Any reference code? BTW: I searched all codes from WME SDK, no such sample code. thanks! George 回答1: Microsoft and the content mafi^H^H^H^Hindustry are trying their best to make this impossible. You will be far better of searching for "open source screen audio capture" than browsing any officially supplied documentation/example code - I would be seriously surprised if Microsoft
