c++ DirectX 9 Code

Hello i have the following code i have problems with:

// esp_dll.h
#include <windows.h>
#include "d3dx9.h"
#include <d3d9.h>
#pragma once
using namespace System;
namespace esp_dll {
public ref class Class1
    {
		    void SetModelColor(LPDIRECT3DDEVICE9 pDevice, float r, float g, float b, float a, float glowr, float glowg, float glowb, float glowa)
			    {
				    float lightValues[4] = {r, g, b, a};
				    float glowValues[4] = {glowr, glowg, glowb, glowa};
				    pDevice->SetPixelShaderConstantF(1, lightValues, 1);
				    pDevice->SetPixelShaderConstantF(3, glowValues, 1);
			    }
    };
}

Its not working when i try to call SetPixelShaderConstantF(pDevice, 3, {1.0f, 1.0f, 1.0f, 1.0f}, 1);
