WinStationShadow API Function

[Remko]

Olli,

I made a type in the mail I sent you, what I meant to say is:
I misinterpreted WinStationShadowStop, I was thinkin way too complicated. We don't need to watch for session state change event and call WinStationShadowStop manually. When you press the hotkey it's done for you. So this function is only there if you want to stop remote control programmatically (why would one want to do that, the app that started is invisible?).
When I pass a PWideChar as second parameter for WinStationShadow nothing happens (no remote control), when I pass ULONG 0 it works.
If you look at the documentation from Citrix's Shadow API (actually windows terminal server API's are based on the winframe API's):

BOOL WINAPI WFShadowSessionW(
IN LPWSTR pServerName,
IN ULONG SessionID,
IN ULONG HotKey,
IN ULONG HKModifier,
);

There Servername is passed instead of a handle, so I tried passing ServerName as the second parameter. Nothing happens.

When I look at the Shadow.exe commandline utility, this is the syntax:
SHADOW {sessionname | sessionid} [/SERVER:servername] [/V]

sessionname Identifies the session with name sessionname.
sessionid Identifies the session with ID sessionid.
/SERVER:servername The server containing the session (default is current).
/V Display information about actions being performed.

So perhaps the string could be sessionname? That would make sense, either supply sessionname or sessionid. The other thing is that parameter 1 from WinStationOpenServerW seems to be equal to our parameter 2.
