Active window code XP_Vista (1203172)

As part of an existing project we need assistance developing a piece of native XP / Vista code to identify the (currently) active / front window and related information of an XP or Vista based computer. We require a Windows (XP / Vista) DLL or suitable equivalent that can be called by the Java utility to provide the required information (the window name, the parent application and if possible the associated file / file path or URL) in a suitable format. More details are provided in the brief (Active Window Brief [login to view URL])
