Revision 1.7 2002/04/26 18:24:16 rainy Modified the Update method to support disabled measures. Revision 1.6 2002/03/31 09:58:54 rainy Added some comments Revision 1.5 2001/09/26 16:27:15 rainy Changed the interfaces a bit. Revision 1.4 2001/09/01 13:00:10 rainy Slight changes in the interface. The value is now measured only once if possible. Revision 1.3 2001/08/19 09:15:21 rainy Added support for value invert. Revision 1.2 2001/08/12 15:45:45 Rainy Adjusted Update()'s interface. Revision 1.1.1.1 2001/08/11 10:58:19 Rainy Added to CVS. */ #pragma warning(disable: 4996) #include "MeasureMemory.h" /* ** CMeasureMemory ** ** The constructor ** */ CMeasureMemory::CMeasureMemory(CMeterWindow* meterWindow) : CMeasure(meterWindow) { m_Total = false; } /* ** ~CMeasureMemory ** ** The destructor ** */ CMeasureMemory::~CMeasureMemory() { } /* ** Update ** ** Updates the current total memory value. ** */ bool CMeasureMemory::Update() { if (!CMeasure::PreUpdate()) return false; MEMORYSTATUSEX stat; stat.dwLength = sizeof(MEMORYSTATUSEX); GlobalMemoryStatusEx(&stat); // Doesn't measure values > 4GB.
