I am developing a game engine using DX11. I am following a tutorial at http://www.rastertek.com/. I have done tutorial 2. The problem is that, when I try to change the color values, the window remains black. The relevant code is:

Each time I change the parameters in theBeginScene() call, no matter what those are (i tried values ranging from 1.0f to 256.0f on the red), the window is always black and there isn't the windows top three buttons (close, minimize, expand). What am I doing wrong? Any help appreciated.
I am following the same tutorials,
It's floating point value between 0 and 1.
so in your case for red color it's
bool Graphics::Render()
{
m_D3D->BeginScene(1.0f, 0.0f, 0.0f, 1.0f);
m_D3D->EndScene();
return true;
}
Don't forget to set opacity to 1.0 the last value.
Good luck for the next ones.

Suddenly, the final result represents the image with nonuniform "lightened" stripes.
link to image http://savepic.org/7623429.jpg:
I've tried to change viewpoint parameters, that led to change the number of visible stripes and their shade, but I can't understand the cause of appearance of different blue/orange shades (in code their colors are uniform). Also, if I generate texture that is evenly filled with one color, i.e:
for( UINT row = 0; row < desc.Height; row++ )
{
UINT rowStart = row * mappedTex.RowPitch;
for( UINT col = 0; col < desc.Width; col++ )
{
UINT colStart = col * 4;
pTexels[rowStart + colStart + 0] = xxx; // Exact color has no reason
pTexels[rowStart + colStart + 1] = yyy;
pTexels[rowStart + colStart + 2] = zzz;
pTexels[rowStart + colStart + 3] = ttt;
}
}
there is no effect of nonuniform shade of the final displayed texture.
I have a function GetCamImage that returns the image from camera as:
unsigned char* p = GetCamImage(...);
I need to create ID3D11Texture2D from this data. How can I do it in DirectX 11?
Thanks
It depends on what the format of the actual content in that p is, as well as the width, height, and stride. Assuming the image is an RGBA 32-bit format with simple byte pitch alignment and sized as w by h, then it would be something simple like:
D3D11_SUBRESOURCE_DATA initData = {0};
initData.pSysMem = (const void*)p;
initData.SysMemPitch = w * 4;
initData.SysMemSlicePitch = h * w * 4;
D3D11_TEXTURE2D_DESC desc;
desc.Width = w;
desc.Height = h;
desc.MipLevels = 1;
desc.ArraySize = 1;
desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
desc.SampleDesc.Count = 1;
desc.SampleDesc.Quality = 0;
desc.Usage = D3D11_USAGE_DEFAULT;
desc.BindFlags = D3D11_BIND_SHADER_RESOURCE;
desc.CPUAccessFlags = 0;
ID3D11Texture2D* tex = nullptr;
HRESULT hr = d3dDevice->CreateTexture2D( &desc, &initData, &tex );
if (FAILED(hr))
...
When creating a rasterizer I set the rasterizer description like so:
rasterDesc.AntialiasedLineEnable = false;
rasterDesc.CullMode = D3D11_CULL_BACK;
rasterDesc.DepthBias = 0;
rasterDesc.DepthBiasClamp = 0.0f;
rasterDesc.DepthClipEnable = true;
rasterDesc.FillMode = D3D11_FILL_SOLID;
rasterDesc.FrontCounterClockwise = true;
rasterDesc.MultisampleEnable = false;
rasterDesc.ScissorEnable = false;
rasterDesc.SlopeScaledDepthBias = 0.0f;
This works fine. But as I change FrontCounterClockwise to false. Nothing is rendered (I guess everything is culled). Do I missunderstand the purpose of FrontCounterClockwise? Because I was expecting, that it would take colockwise faces as front faces instead of counter clockwise ones. What am I doing wrong?

The first thing to clarify is a back face in Direct3D is not the face behind you, the word "back" here does not mean the orientation in normal word, it means the vertex order, all faces except the front faces were treated as back faces.
regarding your question, you said the code below works fine.
rasterDesc.CullMode = D3D11_CULL_BACK;
rasterDesc.FrontCounterClockwise = true;
what do you mean by "fine" here? every face was fine or just some of them are fine? if every face was fine, that means
You tell D3D to cull the back face
You define your vertex in counter-clockwise for every face
so you see every faces rendered well since they were treated as front face by you settings, then you change FrontCounterClockwise to false as below.
rasterDesc.FrontCounterClockwise = false
that means, you tell d3d the faces which defined in counter-clockwise is back face, so D3D culls all of the faces, thus nothing was rendered.
NOTE:
in Direct3D 10/11, a front face was determined not only by vertex order, it also depends on the value of FrontCounterClockwise. , this is different with Direct3D 9 which determined only by vertex order.
So in Direct3D 10/11 if
FrontCounterClockwise = true
Faces were treated as front face if it's vertex order is
counter-clockwise
Faces were treated as back face if it's vertex
order is clockwise
FrontCounterClockwise = fase
Faces were treated as front face if it's vertex order is clockwise
Faces were treated as back face if it's vertex order is counter-clockwise
The name "FrontCounterClockwise" could confuse someone, we can separated the words as below
FrontCounterClockwise = true, means front face as vertex in counter-clockwise
is true.
FrontCounterClockwise = false, means front face as vertex in
counter-clockwise is false, to put it another way, front face as vertex in
clockwise is true.
I cannot get my program to correctly choose which models to place in front. I have followed the MSDN code exactly. My code appears to correctly draw all polygons in a particular call of DrawIndexed, but each subsequent call seems to cause models to be drawn in the order they are drawn, not based on whether they are closer to the screen.

I have tried searching extensively, and have followed every tutorial I could find. Nothing fixes it.
In the case of the spheres, depth appears to be correct if viewing from one side, but not the other.
Any help would be appreciated. Thanks.
From OP comment:
The problem ended up being much simpler. I did not set the minimum and
max depth for the viewport object. It worked once I did so.
I had the same problem, it works now:
D3D11_VIEWPORT screenViewport;
/* ... */
screenViewport.MinDepth = 0;
screenViewport.MaxDepth = 1;
/* ... */
context->RSSetViewports(1, &screenViewport);
There are three key steps to Z-Buffering.
Setting the Appropriate Presentation Parameters
Turning On Z-Buffering
Clearing the Z-Buffer
1) Setting the Appropriate Presentation Parameters
D3DPRESENT_PARAMETERS d3dpp;
//...
d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;
EnableAutoDepthStencil
In truth, z-buffering can be complex. Setting this value to TRUE tells Direct3D to automatically create the z-buffer and set it up in a way used most often. There are, of course, uses for the complex method, but we'll stick to simple for now. We'll cover ways the complex method can be useful later in the tutorial.
AutoDepthStencilFormat
This is the format for each pixel in the z-buffer. We don't use the regular pixel format defined in the Presentation Parameters. Instead, we use a special format for z-buffers. This format is D3DFMT_D16. This means that each pixel is 16-bit. There are other formats, but we will not need them for the extent of this tutorial.
2) Turning On Z-Buffering
// d3ddev is your Direct3D device - a variable of type LPDIRECT3DDEVICE9
d3ddev->SetRenderState(D3DRS_ZENABLE, TRUE);
3) Clearing the Z-Buffer
d3ddev->Clear(0, NULL, D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB(0, 0, 0), 1.0f, 0);
By the way this works in DirectX 9.0c. Im not sure if it is compatible with DirectX 11.
Had a similar problem in DirectX10, seems it was initialisation code, I am not sure about the CreateDevice and SwapChain against UNKNOWN driver type, as I have not used that before.
There are a few differences I can see, the Stencil buffer does not specify the operations to perform depth stencil tests against. (Unless this has been specified in the HLSL which is not visible here)
eg:
// Stencil test parameters
dsDesc.StencilEnable = true;
dsDesc.StencilReadMask = 0xFF;
dsDesc.StencilWriteMask = 0xFF;
// Stencil operations if pixel is front-facing
dsDesc.FrontFace.StencilFailOp = D3D10_STENCIL_OP_KEEP;
dsDesc.FrontFace.StencilDepthFailOp = D3D10_STENCIL_OP_INCR;
dsDesc.FrontFace.StencilPassOp = D3D10_STENCIL_OP_KEEP;
dsDesc.FrontFace.StencilFunc = D3D10_COMPARISON_ALWAYS;
// Stencil operations if pixel is back-facing
dsDesc.BackFace.StencilFailOp = D3D10_STENCIL_OP_KEEP;
dsDesc.BackFace.StencilDepthFailOp = D3D10_STENCIL_OP_DECR;
dsDesc.BackFace.StencilPassOp = D3D10_STENCIL_OP_KEEP;
dsDesc.BackFace.StencilFunc = D3D10_COMPARISON_ALWAYS;
In any event, here is a working DirectX10 example, I am pretty sure you can adapt it quickly for DirectX11.
