Question

我写了一个代码试图通过c ++中的winAPI激活windows的高性能电源计划。它似乎适用于所有电源计划（在我的终端，他们被称为平衡，节电和戴尔），除了我感兴趣的高性能计划！我希望代码能够完成所有的电源计划，当找到高性能时，只需将其设置为然后退出。如果有人可以帮助我，我会把我的代码放在下面。提前谢谢！

#include <windows.h>
#include <powrprof.h>
#include <iostream>
#include "stdio.h"
#include <ntstatus.h>
#include <string>
#pragma comment(lib, "powrprof.lib")

using namespace std;


int main(int argc, char **argv) {


//////////////////  SET ACTIVE HIGH PERFORMANCE PLAN  ///////////////////


//Variables
UCHAR displayBuffer[64] = " ";
DWORD displayBufferSize = sizeof(displayBuffer);
GUID buffer;
DWORD bufferSize = sizeof(buffer);

//Go throught the machine's power plans and activate the high performance one
for(int index = 0; ; index++)
{

    if (ERROR_SUCCESS == PowerEnumerate(NULL,NULL,&GUID_VIDEO_SUBGROUP,ACCESS_SCHEME,index,(UCHAR*)&buffer,&bufferSize) )
    {
        if (ERROR_SUCCESS == PowerReadFriendlyName(NULL,&buffer,&NO_SUBGROUP_GUID,NULL,displayBuffer,&displayBufferSize) )
        {
            wprintf(L"%s\n", (wchar_t*)displayBuffer);


            if( 0 == wcscmp ( (wchar_t*)displayBuffer, L"High Performance" ) )
            {
                cout << "High Performance Plan Found!\n";
                if (ERROR_SUCCESS == PowerSetActiveScheme(NULL,&buffer) )
                {
                cout << "* Setting Active High Performance Power Plan *";
                //std::cin.get(); //pause
                break;
                }

            }
        }

    }
    else break;
}


return 0;

}

这可以更轻松一点：

PowerSetActiveScheme(0, &GUID_MIN_POWER_SAVINGS);
