How to Know If I am in a Terminal Service (TS) Session?

Question

Is there any windows API function to check if I am in a terminal service session?

Answer 1

Use

GetSystemMetrics(SM_REMOTECONTROL))

To determine if the calling session is being remotely controlled

and

GetSystemMetrics(SM_REMOTESESSION))

to determine if the calling session is associated with a remote session on a terminal server
