c++ - E_INVALIDARG in D3D11 -


i have tried figure out why keep getting e_invalidarg error when running code.

    id3d11buffer * cbperobjectbuffer; cbperobject cbperobj;  cbperobjectbuffer = 0;  d3d11_buffer_desc cbbd; zeromemory( & cbbd, sizeof(d3d11_buffer_desc));  cbbd.usage = d3d11_usage_default; cbbd.bytewidth = sizeof(cbperobject); cbbd.bindflags = d3d11_bind_constant_buffer; cbbd.cpuaccessflags = 0; cbbd.miscflags = 0; cbbd.structurebytestride = 0;  hr = device - > createbuffer( & cbbd, null, & cbperobjectbuffer); if (hr == e_invalidarg) {   messagebox(0, l "[cbperobjectbuffer] invalid parameter passed returning function.", l "error", mb_ok);   return; } else if (hr == e_outofmemory) {   messagebox(0, l "[cbperobjectbuffer] out of memory", l "error", mb_ok);   return; } else if (failed(hr)) {   messagebox(0, l "[cbperobjectbuffer] unknown error occured", l "error", mb_ok);   return; }

i keep getting e_invalidarg error when running code. myself can't seem figure out why error. if point me in right direction i'd greatful! :)

my guess 'cbperobject' not multiple of 16 bytes. constant buffers must multiple of 16 bytes in size.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
