C2259 : 'ID3D11ShaderResourceView' Cannot instantiate abstract class - DX11 - c++

Question

I'm trying to make a texture handler so that I can load texture file names from a text file and then load the textures and store them into a vector and get them whenever I need to draw.
Problem is, i'm getting the C2259 error which breaks before it can compile and was wondering if anyone could help me out.
TextureManager.h
class TextureManager{
private:
std::vector<ID3D11ShaderResourceView> * textures;
public:
TextureManager();
~TextureManager();
void TMLoadTexture(ID3D11Device* d);
ID3D11ShaderResourceView * TMgetTexture(int index);
};
TextureManager.cpp - TMLoadTexture / TMGetTexture
void TextureManager::TMLoadTexture(ID3D11Device* d)
{
std::vector<std::string> files;
files = readFile("textures");
D3DX11_IMAGE_LOAD_INFO loadInfo;
ZeroMemory(&loadInfo, sizeof(D3DX11_IMAGE_LOAD_INFO));
loadInfo.BindFlags = D3D11_BIND_SHADER_RESOURCE;
loadInfo.Format = DXGI_FORMAT_BC1_UNORM;
for(int i = 0; i < files.size(); i++)
{
std::wstring stemp = std::wstring(files.at(i).begin(), files.at(i).end());
LPCWSTR sw = stemp.c_str();
ID3D11ShaderResourceView* temp;
D3DX11CreateShaderResourceViewFromFile(d, sw, &loadInfo, NULL, &temp, NULL);
textures->push_back(*temp);
delete temp;
}
}
ID3D11ShaderResourceView * TextureManager::TMgetTexture(int index)
{
return &textures->at(index);
}
Thanks :)

Since ID3D11ShaderResourceView is an interface, you must use a pointer to access these kind of objects. So:
std::vector<ID3D11ShaderResourceView*> * textures;
Btw, are you sure that you want to use a vector-pointer? I see no reason why a plain vector<...> wouldn't be sufficient.
Then when loading the texture, put the pointer in the vector:
textures.push_back(temp);
And don't delete the texture you just created.
