asp.net mvc 4 - How to maintain the state (history) for breadcrumb -


i'm struggling trying implement breadcrumb functionality directory navigation system.

in application user can upload zip file. once can navigate content of zip file (ie navigate folders , files). implemented logic. want add breadcrumbs on top of page user can click on previous folder , go it. decided create pretty url use numbers (ids) on retrieve upload , folder (or file) database. if user navigation in upload id = 10 , in maindirectory/folder1 , folder1 has id = 100 url localhost:1234/upload/10/dir/100/maindirectory/folder1/. have both id upload , folder (or file).

when creating breadcrumb can retrieve history last part of url don't have id of folders. cannot use folder name key because not unique. thought putting ids on url become ugly, this: localhost:1234/upload/10/dir/99/100/maindirectory/folder1/. idea putting first ids , pretty path.

session came mind rejected because user can navigate in different tabs @ same time, breadcrumb history depends on current page. think information build breadcrumb needs sent on each request.

i cannot think in better design. ideas?

edit: need mirror github navigation system repositories.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
