Examples of GetDC()

com.sun.jna.examples.win32.User32.GetDC()
com.sun.jna.platform.win32.User32.GetDC()
This function retrieves a handle to a display device context (DC) for the client area of the specified window. The display device context can be used in subsequent graphics display interface (GDI) functions to draw in the client area of the window. @param hWnd Handle to the window whose device context is to be retrieved. If this value is NULL, GetDC retrieves the device context for the entire screen. @return The handle the device context for the specified window's clientarea indicates success. NULL indicates failure. To get extended error information, call GetLastError.
