열려있는 모든 창 캡쳐 화면을 windows 7에 저장하려고합니다.모든 열린 창 스크린 샷
문제는 열린 창에 대한 스크린 샷을 얻는 대신 cmd.exe 스크린 샷을 제공한다는 것입니다. 예를 들어 google chrome screenshot 대신 black cmd.exe 스크린 샷을 보여줍니다.
이전에 Windows 10에서 동일한 코드를 시도했지만 작동하지 않는 것 같습니다.
http://www.developerfusion.com/code/4630/capture-a-screen-shot/에서 다음 코드를 사용하여 특정 창의 스크린 샷을 가져 왔습니다.
