SDL_SetWindowGammaRamp ERROR

[gameboy]

@Stan`  This code is more practical, it is simpler, it can effectively solve practical problems.

BTW: we should not delete those settings, should adjust it.

// The hDC DC handle, if NULL, uses the entire screen
// wR wG wB 0-255, default 128
BOOL SetBrightness(HDC hDC, int wR, int wG, int wB)
{
    BOOL bRet = FALSE;
    HDC hGammDC = hDC ? hDC : ::GetDC(NULL);
#pragma pack(push, 8)
    typedef struct _tagD3dGammaramp_t
    {
        WORDred[256];
        WORDgreen[256];
        WORDblue[256];
    } _D3DGAMMARAMP, *LP_D3DGAMMARAMP;
#pragma pack(pop)

    _D3DGAMMARAMP mGamRamp;
    memset(&mGamRamp, 0, sizeof(mGamRamp));
    for (int iIndex = 0; iIndex < 256; iIndex++)
    {
        mGamRamp.red[iIndex] = min(65535, iIndex * (wR + 128));
        mGamRamp.green[iIndex] = min(65535, iIndex * (wG + 128));
        mGamRamp.blue[iIndex] = min(65535, iIndex * (wB + 128));
    }
    LPVOID lpRamp = &mGamRamp;
    bRet = SetDeviceGammaRamp(hGammDC, lpRamp);
    if (hDC == NULL && hGammDC)
    {
        ::ReleaseDC(NULL, hGammDC);
    }
    return bRet;
}

@gameboy that code will not work, nor will the previous examples you posted do either. Some are C not C++ which isn't a problem by itself, but we don't code in C anywhere, some are not cross platform, example 

#include <windows.h>

Will only work on windows.

Nobody actually needs to change the gamma in the game, you can do it using external software if you need to.

Also, when posting code snippets, please use the code tools from the forums. It's unreadable otherwise. Thanks.

It's fixed now cheers

Did a re installation fix it ?

[gameboy]

The problem has been fixed

[weridetogether6]

I am having this problem again I don't know how to put the code in to fix this either

What did you change when it last worked ?
