WinApi: Interaction with SysListView32 under locked workstation

Asked by: EPAM_Systems

Hi Experts,

I there a way to emulate mouse events like WM_LBUTTONDBLCLK (SendMessage) or keypress (SendKey/SendInput: ENTER) to SysListView32 under locked workstation?

At the moment no mouse or keyboard events are allowed under locked workstation, but my application is interacting with another application
using winapi messages and I can't find any other way implement this.

Thank you.

I'd rather go the route to detect when the workstation i locked, suspend your interaction and resume it after the machine has been unlocked again. See http://msdn.microsoft.com/en-us/library/aa374783(VS.85).aspx ("Creating a Winlogon Notification Package") and http://msdn.microsoft.com/en-us/library/aa379380(VS.85).aspx ("Registering a Winlogon Notification Package"). All you have to do is looking out for the "Lock" and "Unlock" events.

BTW, if you have to support Vista also, these are superseded by the System Event Notification Service (SENS) - see http://msdn.microsoft.com/en-us/library/aa376860.aspx ("ISensLogon Interface") for more on that.

I don't need to detect when the workstation is locked - I need to interact with SysListView32 under locked workstation.

 

by: jkrPosted on 2009-02-12 at 18:43:20ID: 23629328

... which you cannot. Thus the suggestion to stop interacting with it until it is unlocked again.
