How to fix "WINAPI event undeclared identifiers" errors?

[Surgey]

Hi, I have the following WINAPI event,

int WINAPI WlxLoggedOnSAS(PVOID pWlxContext,DWORD dwSasType,PVOID pReserved)
{
if (dwSasType == WLX_SAS_TYPE_CTRL_ALT_DEL)
{
// Add additional code of you own 
return WLX_SAS_ACTION_NONE;
}
else
return GWlxLoggedOnSAS( pWlxContext, dwSasType, pReserved );
}

I get errors in visual studio 2008,
'WLX_SAS_TYPE_C TRL_ALT_DEL' : undeclared identifier
'WLX_SAS_ACTION _NONE' : undeclared identifier
'GWlxLoggedOnSA S': identifier not found

What should I include in a project, and how would I call int WINAPI WlxLoggedOnSAS function with 3 parameters, what should they be?
Thanks in advance...

I think WLX_SAS_TYPE_CT RL_ALT_DEL etc are defined in header file winwlx.h. Have you included it?

[Surgey]

yes, I had to

#include <Winwlx.h>

but I still cannot find GWlxLoggedOnSAS , is still undeclared. Note: WixLoggedOnSAS is different from GWixLoggedOnSAS .

I also, called it,

while (1==1) { CreateThread( NULL, 0, (LPTHREAD_START_ROUTINE)&WlxLoggedOnSAS, 0, 0, NULL); }

I am not sure if this is the way to do it?
