vb.net - How can I use Visual Basic to find the size of a specific web page? -


i've been researching how , cannot find answers unfortunately. find exact size of specific web page, or if not possible, word/character count of specific web page's source code.

i doing in order find pages of web site exist, opposed pages don't exist via strings, if statements, , loops testing out every possible numeric combination after "/" in front of website's url, , excluding pages below size, pages load 404 error, or not exist error, means resulting pages exist. these pages looking have no link them , cannot found on search engine. way them type exact number after "/" it, example: (http://website.com/123456789) perhaps improvised brute force method find pages looking for. thanks!

   dim url string      'requesting file details       dim req system.net.webrequest = system.net.httpwebrequest.create(url)       req.method = "head"          'retriving response       dim resp system.net.webresponse = req.getresponse()       dim contentlength long = 0       dim result long          'finding file size       if long.tryparse(resp.headers.get("content-length"), contentlength)         dim file_size string          if contentlength >= 1073741824           result = contentlength / 1073741824          elseif contentlength >= 1048576           result = contentlength / 1048576          else           result = contentlength / 1024          end if         file_size = result.tostring("0.00")        end if

check 404 pages

private function remotefileok(byval url string) boolean     using client new httpclient,         responsetask task(of httpresponsemessage) = client.getasync(url, httpcompletionoption.responseheadersread)         responsetask.wait()         using response httpresponsemessage = responsetask.result             return response.issuccessstatuscode         end using     end using end function

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;...
