I had to re-read your post carefully. What I believe you would have to do is to read the HLSL Binary like you do with binary files. then use the function D3DX10CompileFromMemory - there's possibly some interesting tutorials. I'll need to convert my shaders into binary to protect my game so modders won't get funny with it. If you're looking into how you would actually read a whole binary file - you would have to get the full size of the file and create a pointer with that size.

char *data;
unsigned long fileSz; 

std::ifstream input("myshaderbinary.hlsl", std::ios_base::binary);
if(input) { //-- make sure it's opened first.
        input.seekg(0, std::ios_base::end);
        fileSz = input.tellg(); //-- Get the file size.
        input.seekg(0,std::ios_base::beg); //-- rewind to beginning of file.

        if(fileSz > 0)  {  //-- just making sure there's over zero.
        data = new char[fileSz]; //-- Allocate enough storage to stuff the data.
        input.read(data, 0, sizeof(char) * fileSz);
         }
}

//-- Now we can continue to use D3DX10CompileFromMemoryA function. 

The D3DX10CompileFromMemoryA reads ascii such as char or const char. it won't read const wchar_t * or wchar_t* or LPCWSTR which is shortened for const wchar_t*. The D3DX10CompileFromMemory will read the LPCWSTR, wchar_t * and const wchar_t*.

I'm sure there's some examples are here or on google but because I haven't read any shader files in binary yet - I believe this is the approach you'll have to take. Anyone that would like to point out a more effective way then you'll most likely benefit from them. I'm not too sure yet. Just remembered how I loaded my video textures with D3DX11LoadShaderResourceFromMemoryA bit.

the input.read is incorrect. it should be input.read(data, sizeof(char) * fileSz);
