CompareFileTime - Application Error...The memory could not be "read". – C / C++ – Fórum – Programujte.com

Jsem biginner...
V kodu mam CompareFileTime, asi neco spatne nastavuji...
Application Error: The instruction at "0x7c810ae4" referenced memory at "0x01c76f9a". The memory could not be "read".

}

nemam moznost spustit tuto zalezitost, ale skus len tak zo srandy.

GetFileTime(

           HANDLE (File2),

           LPFILETIME (&lpCreationTime2),

           LPFILETIME (&lpLastAccessTime2),

           LPFILETIME (&lpLastWriteTime2)

           );

// to zopakovat aj pre 1

FILETIME CreationTime2, LastAccessTime2, LastWriteTime2;

GetFileTime( File2, &CreationTime2, &LastAccessTime2, &LastWriteTime2 );



CompareFileTime( &CreationTime1, &lpCreationTime2 );

To není ani přetypování, to je spíš konstruktor! Jenže u struktury? Divím se, že se to vůbec přeloží...

Jop je to konstrukcia ale c C++ sa da pretypovat dvoma sposobmi:

//klasicke pretypovanie z Cecka

int b = (int)a;



//alebo aj 

int c = int(a);
