How to know if the NT WorkStation is locked ?

I'm programming in C++.

I want to know if the NT WorkStation where my program is running is locked, so I can start a batch process.

I couldn't find any function that informs about us, so I guess that I have to query the registry or something.

Thanks.

If it is enough to know whether a screensaver is running, you could use

BOOL bRunning;
SystemParametersInfo ( SPI_GETSCREENSAVERRUNNING, 0, &bRunning, 0);

if ( bRunning) {
// is running
}

No, because we want to run the batch process when the user goes for lunch and the user MUST lock the workstation when he goes for lunch. The screen saver can run at other times.

Call OpenInputDesktop and if it returns handle to winlogon desktop than station is locked. The only problem will be is that if it's locked and screen saver is running than you get handle to screen saver desktop.

Or maybe you can open winlogon desktop and get active window from it and check what is it.
