A connection timeout can occur if the HttpClient is not able to connect to the HTTP server if, for example, the URL is not correct or the server is not available A socket timeout can occur if the HttpClient fails to receive a response within a defined time period In other words, the HttpClient was able to connect to the server, but the server failed to return a response within the allocated time limit Now that you understand the types of exceptions that might occur, how do you deal with them Fortunately, the HttpClient is a robust framework that takes most of the burden off your shoulders In fact, the only exception types that you ll have to worry about are the ones that you ll be able to manage easily. birt code 39, birt data matrix, birt barcode tool, birt pdf 417, microsoft word 2010 qr code, code 128 font word 2010 .net ean 13 reader EAN13 Barcode Control - CodeProject

In most situations, just submitting information to the server is not enough. You might want to invoke an action or an action listener on the server. That s easily done using the standard action and actionListener attributes. Notice that when using an action attribute to point to an action s server-side method, the method has to return null in order for a partial-page update to happen. Keep in mind that the response returned will be used to update the browser DOM. Navigating to a different page (view) will most likely result in completely different content being returned.

C# . NET EAN - 13 recognition reader control component is used to scan & read EAN - 13 barcode from image in C#. NET class applications. unpack_int(msg[2..3]), unpack_int(msg[4..5]) == 0 msg = msg[6..-1] instances << {:book_instance_id => instid, :library_id => libid, :lended => lended } end BookDescription.new(id.to_i, name, authors, isbn, instances) end This code isn t too clean; there s probably a DSL just waiting for you to find it in here. However, the workings of this code are procedural and simple. You first unpack the ID of the book description, then the name. You fetch the length of the array of authors and then fetch each author name. After that, you get the ISBN and then walk through the list that provides instance information about this book description. Finally, you create a new BookDescription object containing this information. The search method looks like this: def self.search(name, author) tid = @@current_trans_id += 1 Connection.send(tid.to_s, OP_SEARCH + s(name) + s(author)) msg = sleep_until(tid) Transactions.delete(tid) unpack_search_list msg end It uses the unpack_search_list method, which is much like the get_book_description method. That s because it needs to do the same thing, but repeatedly. The only difference is that this method unpacks more than one entry and returns a list of BookDescription objects: def self.unpack_search_list(msg) len = msg[0] msg = msg[1..-1] all = [] len.times do id = unpack_int(msg[0..1]) msg = msg[2..-1] nm_len = msg[0] name = msg[1..nm_len] msg = msg[(nm_len+1)..-1] authors = [] len2 = msg[0] msg = msg[1..-1] len2.times do a_len = msg[0] auth = msg[1..a_len] msg = msg[(a_len+1)..-1] authors << auth end As we said earlier, there are three types of exceptions that you can expect: transport exceptions, protocol exceptions, and timeouts The HttpClient takes care of transport exceptions by detecting transport issues and retrying requests (which works very well with this type of exception) Protocol exceptions are exceptions that can generally be. .net ean 13 reader .
