Currently I am making a game in C++ using DirectX9 (and starting to wish I'd started in DX11) and I am currently working on changing the game resolution. My problem is that when I reset the graphics device, my meshes no longer draw and I can't see how to resolve the issue.

Currently I am making a game in C++ using DirectX9 (and starting to wish I'd started in DX11) and I am currently working on changing the game resolution. My problem is that when I reset the graphics device, my meshes no longer draw and I can't see how to resolve the issue.

At the moment, fonts, textures and meshes are all loaded and pointers to them are stored in maps to be retrieved when needed:

typedef std::map<string, IDirect3DTexture9*> TexMap;
typedef std::map<string, ID3DXMesh*> MeshMap;
typedef std::map<string, ID3DXFont*> FontMap;
TexMap textureList;
MeshMap meshList;
FontMap fontList;

HRESULT LoadMesh( IDirect3DDevice9* pd3dDevice, LPCWSTR file, string key)
{
  //load and store a mesh from file
  ID3DXMesh* mesh;
  D3DXLoadMeshFromX(file, D3DXMESH_MANAGED, pd3dDevice, NULL, NULL, NULL, NULL, &mesh);

  if (meshList.find(key) != meshList.end())
  {
   meshList.erase(meshList.find(key));
  }
  meshList.insert(MeshMap::value_type(key, mesh));
  return S_OK;
}

The same process is used to load Meshes and Fonts:

...
D3DXCreateTextureFromFileEx(pd3dDevice, file, 512, 512, 0, 0, D3DFMT_UNKNOWN, D3DPOOL_MANAGED, D3DX_DEFAULT, D3DX_DEFAULT, 0xFF000000, NULL, NULL, &tex);
...

...
D3DXCreateFont( pd3dDevice, Height, Width, Weight, MipLevels, Italic, CharSet, OutputPrecision, Quality, PitchAndFamily, pFacename, &font );
...

I assume from the settings that both Meshes and Textures are managed and do not need to be released and re-acquired when the device is reset.

Right now, for the sake of testing I have it change the resolution on a button click:

if (input->MouseDown(0) && gui->PointIntersection(&buttonStart, input->GetMouseScreen(&d3dPresentParameters)))
{
d3dPresentParameters.BackBufferWidth = 800;
d3dPresentParameters.BackBufferHeight = 600;
assets->OnLostDevice();
graphicsDevice->Reset(&d3dPresentParameters);
assets->OnResetDevice();
assets->test(graphicsDevice);
}

The assets methods are as follows, resetting the fonts:

void OnLostDevice()
{
  FontMap::iterator it;
  for(it = fontList.begin();
		it != fontList.end();
		it++)
  {
   it->second->OnLostDevice();
  }
}
void OnResetDevice()
{
  FontMap::iterator it;
  for(it = fontList.begin();
		it != fontList.end();
		it++)
  {
   it->second->OnResetDevice();
  }
}

The test method simply re-loads the meshes. I just added this in to be sure, but it makes no difference:

void test(IDirect3DDevice9* graphicsDevice)
{
  LoadMesh(graphicsDevice, L"../Assets/Tile.x", "Game_Mesh_Tile");
  LoadMesh(graphicsDevice, L"../Assets/Wall.x", "Game_Mesh_Wall");
  LoadMesh(graphicsDevice, L"../Assets/Icon.x", "Game_Mesh_Icon");
  LoadMesh(graphicsDevice, L"../Assets/Border.x", "Game_Mesh_Border");
}

Finally, here's my initial Device creation:

d3dpp.Windowed = true;
d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.hDeviceWindow = hWindow;
d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;
d3dpp.BackBufferWidth = SCREEN_WIDTH;
d3dpp.BackBufferHeight = SCREEN_HEIGHT;
d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.AutoDepthStencilFormat = D3DFMT_D24S8;

if( SUCCEEDED(d3d->CheckDeviceMultiSampleType( D3DADAPTER_DEFAULT,
	 D3DDEVTYPE_HAL , D3DFMT_X8R8G8B8, FALSE,
	 D3DMULTISAMPLE_8_SAMPLES, NULL ) ) )
{
  d3dpp.MultiSampleType = D3DMULTISAMPLE_8_SAMPLES;
}
  // create a device class using this information and the info from the d3dpp stuct
	d3d->CreateDevice(D3DADAPTER_DEFAULT,
					  D3DDEVTYPE_HAL,
					  hWindow,
					  D3DCREATE_SOFTWARE_VERTEXPROCESSING,
					  &d3dpp,
					  &d3ddev);

So basically I am unsure what is causing my meshes to not draw. The program does not crash, I just basically say some UI textures drawn, but no 3D objects. If I remove the device reset, I am, of course, able to see them.

Any advice or suspicions are welcome.

P.S. The reloading of the meshes in test() is done before it actually assigns the meshes to objects. I also have a button-press trigger for resetting the device after the game objects are loaded and displaying and they simply disappear as soon as the button is pressed.

Also, just for the record:

HRESULT answer = graphicsDevice->TestCooperativeLevel();

answer = S_OK after the reset
