    #include <windows.h>

    Hi,
    Where is windows.h?! QT could not find it?...

    Should be part of the windows compiler. What are you using?

        You're in a severe mess if your MSVC doesn't have/find windows.h!

          Working example compiled with MSVC: http://rextester.com/HCD11597

          #include <iostream>
          #include <windows.h>
          #include <psapi.h>
          double getUsedMemoryMB()
          {
              PROCESS_MEMORY_COUNTERS pmc;
              GetProcessMemoryInfo(GetCurrentProcess(), &pmc, sizeof(pmc));
              return static_cast<double>(pmc.WorkingSetSize) / static_cast<double>(1024 * 1024);
          }
          int main()
          {
              std::cout << getUsedMemoryMB();
          }

                Hi,
                Finally I got it... Calital letter problem. It must be:

                #include "Windows.h"
                #include "Psapi.h"

                Is returning number STACK or HEAP?... And what is the limit?...

                  @Mucip Windows filing system is case-insensitive, so no idea why you say you require capitals.

                    It's the sum of both

                    And what is the limit?

                    for 64bit systems the limit is just the hardware (how much RAM you have) for 32bit systems is the lower of the hardware memory and 4GB

                      Dear @VRonin
                      Well, what about the 64K STACK limit I remember from old times?...
