How to use a secondary video adapter in Direct3D?

Question

C++ / C#

Hello!
I can not figure out how to specify a secondary adapter (second video card) in Direct3D (Version 9)?
It seems that if we specify D3DADAPTER_DEFAULT, then it points to the primary video adapter,
but how to point to the secondary one?
I have a laptop, the first graphics card is Intel HD Graphics and the second is AMD Radeon, and when I start my application, only the first one works.

d3d9->CreateDevice(
               D3DADAPTER_DEFAULT,  // <-??????
  deviceType,       
    hwnd,               
    vp,                 
      &d3dpp,            
      device);

Answer 1

In 9k, apparently using https://msdn.microsoft.com/en-us/library/windows/d...
where Adapter handles to sort through until it starts to swear.
At 11, they somehow made it easier.

Answer 2

#define D3DADAPTER_DEFAULT 0
Secondary respectively 1
IDirect3D::GetAdapterCount gives you an interval of 0 to N-1 number of video cards. But in general they write that the second video card is not always detected (for example, intel integrated video cards)
