How to know fast if another computer is accesible in AS3 (Adobe Air)

Cannot get data using LINQ in MVC
c#,asp.net-mvc,linq,asp.net-mvc-4
Ensure term matches the case of the data. As all the data is loaded (.ToList() in the DAL), the .Where clause uses .Net comparison rather than SQL comparison: var vehicle = _service.GetAll().Where(c => c.Name.StartsWith(term, StringComparison.OrdinalIgnoreCase)... If, in the future, you want to change this to Contains, you can add an...

Why mozilla changes the characters when i use the .net mvc statement redirect?
c#,asp.net-mvc-4,redirect,mozilla
%E2%80%8B is a URL-encoded, UTF-8 encoded ZERO-WIDTH SPACE character. You likely have one hiding in your application setting file for the ProActiveOffice-URL value. It was maybe pasted in that way, if you copied the URL from somewhere.
Strings vs binary for storing variables inside the file format
Speaking as someone who's had to do exactly what you're talking about a number of time, rr got it basically right, but I would change the emphasis a little. For file versioning, text is basically the winner. Since you're using an hdf5 library, I assume both serializing and parsing are...

Why is my linked list only printing last entry?
The problem is the way you are treating the result of strtok: you are setting its value right into the node, instead of copying it. Make a copy of name when adding a node: void push(node ** head, int uid ,char* uname) { node * new_node; new_node = malloc(sizeof(node)); new_node->uid...

Python3 create files from dictionary
Remove the if not len(key) != len(aDict) and the break. What you probably wanted to do is stopping the loop after iterating all the keys. However key is one of 'OG_1', 'OG_2', 'OG_XX', it's not a counter or something like that. Replace open("key", "w") with open(key + ".txt", "w")....

Reading a text file with Tabs
There's no tab entity defined in ISO-8859-1 HTML, so I think you can replace tab characters with some characters: if (File.Exists(path)) { using (TextReader tr = new StreamReader(path)) { while (tr.Peek() != -1) { var htmlLine = tr.ReadLine().Replace("\t", " ") + "<br/>"; Response.Write(htmlLine); } } } ...

Saying there are 0 arguments when I have 2? Trying to open a CSV file to write into
I believe the problem is with Dir.foreach, not CSV.open. You need to supply a directory to foreach as an argument. That's why you are getting the missing argument error. Try: Dir.foreach('/path/to_my/directory') do |current_file| I think the open that is referenced in the error message is when Dir is trying to...
