Direct3D - D3DERR_DEVICENOTRESET ???

Kuldren

Ich hab folgenden Code um zu testen ob ich in meinem Programm alles darstellen kann:

bool CDirect3D::check_device(){

switch(m_lpD3DDevice->TestCooperativeLevel())
 {
 case D3DERR_DEVICELOST: return false;
 case D3DERR_DEVICENOTRESET:
  {
  if(FAILED(m_lpD3DDevice->Reset(&PParams)))
   {
   MessageBox(NULL,"Reset failed!","CheckDevice()",MB_OK);
   return false;
   }

  CreateFont();

  return true;
  }
 default: return true;
 }
}

Allerdings lässt sich das Device einfach nicht reseten...
Es erscheint nur andauernd die MessageBox "Reset failed"...

Kennt ihr vielleicht einen Grund dafür warum es sich nicht reseten lässt?[cpp]

Aus der Dokumentation:

If the device can be restored, the application prepares the device by destroying all video-memory resources and any swap chains. Then, the application calls the Reset method. Reset is the only method that has an effect when a device is lost, and is the only method by which an application can change the device from a lost to an operational state. Reset will fail unless the application releases all resources that are allocated in D3DPOOL_DEFAULT, including those created by the CreateRenderTarget and CreateDepthStencilSurface methods.
