Description & Usage

LockWorkStation locks the computer, preventing anybody from entering input until either the user who locked it or an administrator enters his or her password. This function does the same thing as though the user had pressed Ctrl+Alt+Del and selected "Lock Workstation."

If successful, the function returns a non-zero value. If an error occured, the function returns zero (use GetLastError to get the error code).

Visual Basic-Specific Issues

None.

Parameters

None.

Example

Lock the workstation when the user clicks the command button named cmdLock. Obviously, to use this example, you must place a command button named cmdLock on a form window.
