CMemoryState funzt net...

Hallo,

was mache ich hier falsch, da ich Fehlermeldungen zu dem CMemorySate bekomme?
Fehlermeldung:
-----------------------------------------------------
Kompilierung läuft...

error C2079: 'msOld' verwendet undefiniertes struct 'CMemoryState'
error C2228: Der linke Teil von '.Checkpoint' muss eine Klasse/Struktur/Union sein
error C2228: Der linke Teil von '.DumpAllObjectsSince' muss eine Klasse/Struktur/Union sein
Fehler beim Ausführen von cl.exe.

socksell.cpp - 3 Fehler, 0 Warnung(en)

Danke für Tips.............

CMemoryState msOld;
msOld.Checkpoint();

File *mCFile;
mCFile = new File();

MApp *CApp;
CApp = new MApp();

mSocket *pSocket;
pSocket = new mSocket();

CISess *CISession;
CISession = new CISess();

ASocket *AsySocket;
AsySocket = new ASocket();

msOld.DumpAllObjectsSince();

As with other diagnostics, the CMemoryState diagnostics are only available in debug versions of your program. A debug version must have the _DEBUG constant defined.

und

Note Declarations of objects of type CMemoryState and calls to member functions should be bracketed by #if defined(_DEBUG)/#endif directives. This causes memory diagnostics to be included only in debugging builds of your program.

Thank you for your swiftly reply.........;)
