Auto Screen Capture

Auto Screen Capture is a demonstrative application built to showcase the use of several methods from which the USER32.DLL can capture computer screens.
USER32.DLL is implemented in Windows to allow the creation and operation of interface elements. It uses the RECT and POINT structures, as well as functions such as WindowFromPoint(), GetCursorPos(), GetWindowRect(), GetClientRect(), DrawFocuRect(), InflateRect(), GetDesktopWindow(), GetForegroundWindow(), GetWindowDC(), ReleaseDC() and SetCapture().
The example at hand enables you to capture multiple screens at a user specified interval. You can set the capture time in milliseconds and can also choose the number of frames you want to capture. Moreover, the application can be set to record screens until the computer is restarted. It’s also possible to start capturing images when a certain key is pressed.
The application displays the captured computer screens in a small preview section. A list of all the recorded images is also available, making it easy for you to scroll through them. In case you want to see them all, one by one, the application example is fitted with buttons that allow you to navigate back and forward, one frame at a time but you can also have it play a slideshow from them.
