C++: check if computer is locked

Question

I\'m trying to figure out whether the computer is locked.

I\'ve looked at LockWorkStation function, but the function that I\'m hoping to find is IsWorkStation

Answer 1

From the same MSDN link you gave, the third paragraph of "Remarks" says:

This function has the same result as pressing Ctrl+Alt+Del and clicking Lock Workstation. To unlock the workstation, the user must log in. There is no function you can call to determine whether the workstation is locked. To receive notification when the user logs in, use the WTSRegisterSessionNotification function to receive WM_WTSSESSION_CHANGE messages. You can use session notifications to track the desktop state so you know whether it is possible to interact with the user.
