All dimensions retrieved by GetSystemMetrics are in pixels.
The SM_REMOTESESSION system metric is used in a Terminal Services environment. If the calling process is associated with a Terminal Services client session, the return value is nonzero.
The SM_REMOTECONTROL is used in a Terminal Services environment. Its value is nonzero if the current session is remotely controlled; otherwise, 0.

System Metrics Foundation Class included in VFP8 and 9 installations provides access to system metric information as mousewheel present, number of mouse buttons, and number of monitors are provided with the class, but any valid system metric can be queried.

Allegedly, both GetSystemMetrics(SM_CXSIZE) and GetTitleBarInfo return wrong values for Vista Aero. For the latter, sending the WM_GETTITLEBARINFOEX suggested to be a replacement.
