Lock Windows 2000 Instantly


Locking an NT workstation has never been easy. Windows 2000 has a new function, LockWorkStation, that can lock the machine instantly with a single API call:
 
Private Declare Function LockWorkStation Lib _
	"user32.dll" () As Long

Call LockWorkStation

In fact, because this function requires no parameters, you can reduce the code to a single line, as well as make it callable from 16-bit code, by invoking it through rundll32:
 
Call Shell("rundll32 user32.dll,LockWorkStation", _
	vbNormalFocus)

The workstation locks instantly when this line is executed. Here
