Undeclared Identifier in an ATL project - what am I doing wrong?

[Alex K. Angelopoulos (MVP)]

Ok, what am I missing?

I just tried to put together my first simple ATL project. All it does is return
a property value for the current user session, indicating whether it is being
run in a Terminal Services 2000 or higher remote session . I get an undeclared
identifier error on the line

return GetSystemMetrics( SM_REMOTESESSION );

I did a very basic setup on this, only created 1 property, and SM_REMOTESESSION
is defined in "winuser.h". If it makes any difference:

(1) The ref to SM_REMOTESESSION in winuser.h is this:
#if(WINVER >= 0x0500)
#define SM_REMOTESESSION 0x1000

(2) I'm compiling on XP Pro, running VC++6 Enterprise

// CODE BELOW THIS LINE
// Data.cpp : Implementation of CData
#include "stdafx.h"
#include "Wtsc.h"
#include "Data.h"
#include "winuser.h"

/////////////////////////////////////////////////////////////////////////////
// CData

STDMETHODIMP CData::get_IsInTSSession(BOOL *pVal)
{

return GetSystemMetrics( SM_REMOTESESSION );

}
// Actual error message I get is - Data.cpp(14) : error C2065:
'SM_REMOTESESSION' : undeclared identifier

Have you actually set WINVER=0x0500 for your project?

No, I had *not*. Thanks, David.
