VBScript Question (Didn't know where to put it)

[comfroels]

I am terrible at VBScript and am not sure of syntax here I am trying to just check if there is an active rdp session active and if there is to pop up a window saying so.

 
dim IsRemoteSession 
 
 
 bool IsRemoteSession(void)

      return GetSystemMetrics( SM_REMOTESESSION )

 if IsRemoteSession = true then
 MessageBox "RDP Session Active"
 end if

any help would be appreciated
