Tried that.. I VPN in on my phone, run the Android app in VS2017, the app starts on my phone, and Environment.UserDomainName always returns "localhost".
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

|
|
That's pretty much what the Remarks section in the MSDN page says will happen. When I run it on my PC it returns my PC name.
|
|
|
|
|
What I'm trying to accomplish is to determine if the app is being run on our network. The users will VPN in, then run the app. I need to check that their connected before continuing to let app load.
I've also tried "Dns.GetHostAddresses("www.the_domain.com").FirstOrDefault()". This returns a 192.168.... address.
Any idea how to check if the user is VPN's in from an Android app?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

As far as I am aware, this will always return the address related to the system on which the app is running. It's a while since I did this for real.

hi kevin,
you can use IP api to get the isp name,
if the user is connected to VPN then ip will match with the ISP
e.g. https://ipinfo.io/

Can someone help how I can also copy user's desktop folder's subfolders and their files with the code below this text?
For moment I can only copy files from \" + computer + "\c$\Users\Desktop folder but not the subfolders and their files.
string[] dirs = Directory.GetDirectories("\\\\" + computer + "\\c$\\Users\\");
foreach (string item in dirs)
{
FileInfo f = new FileInfo(item);
user2 = "\\\\" + computer + "\\c$\\Users\\"+ f.Name + "\\Desktop";
if (Directory.Exists(user2))
{
user = "C:\\Backup\\" + computer + "\\" + f.Name + "\\Desktop";
Directory.CreateDirectory(user);
DirectoryInfo folder = new DirectoryInfo(user2);
FileInfo[] files = folder.GetFiles();
foreach (FileInfo file in files)
{
string temppath = Path.Combine(user, file.Name);
file.CopyTo(temppath, true);
}
}

What exactly is happening, and why not just use "C:\Users\ ..."?

Hi,
what you need is a recursive method (say DeepCopyDir()) that copies an entire folder by:
(1) copying its files, using Directory.GetFiles and File.Copy for each of them;
(2) copying its subfolders, using Directory.GetDirectories and DeepCopyDir for each of them.

Hi all, first of all I'm a novice when it comes to parsing Json  , I'm attempting ( with some success ) to get information from the OED API, this is my first attempt
using System;
using System.IO;
using System.Net;
using System.Text;
using Newtonsoft.Json.Linq;
namespace OxfordDictionary
{
class Program
{
static HttpWebRequest req = null;
static string PrimeUrl = "https://od-api.oxforddictionaries.com:443/api/v1/entries/en/";
static string uri = PrimeUrl + "crossword";
static string theJson = "";
static HttpWebResponse HWR_Response = null;
static Stream respStream = null;
static StreamReader sr = null;
static void Main(string[] args)
{
req = (HttpWebRequest)HttpWebRequest.Create(uri);
req.Headers.Add("app_id", "my id");
req.Headers.Add("app_key", "app key");
req.Method = WebRequestMethods.Http.Get;
req.Accept = "application/json";
HWR_Response = (HttpWebResponse)req.GetResponse();
respStream = HWR_Response.GetResponseStream();
sr = new StreamReader(respStream, Encoding.UTF8);
theJson = @sr.ReadToEnd();
sr.Close();
var results = JObject.Parse(theJson)["results"];
string value = "";
string name = "";
string output = "";
foreach (JObject o in results.Children<JObject>())
{
foreach (JProperty p in o.Properties())
{
name = p.Name;
foreach (var v in p.Values())
{
value = v.ToString();
output += value;
}
}
}
Console.WriteLine(output);
Console.ReadKey();
}
}
}
which returns
crossword{

the bit I'm interested in is
"definitions": [
"a puzzle consisting of a grid of squares and blanks into which words crossing vertically and horizontally are written according to clues"
I've tried googling but can't find anything to help me, so my question is ? how can I parse definitions[0] ?

The first thing to note is that there are three problems with the JSON data:
1) Remove the introductory "crossword"
2) Remove the trailing "headwordcrossword"
3) Escape the double quotes in the "audiofile" href:
"audioFile": "<a href="http://audio.oxforddictionaries.com/en/mp3/crossword_gb_1_8.mp3">http://audio.oxforddictionaries.com/en/mp3/crossword_gb_1_8.mp3</a>", To:
"audioFile": "<a href=\"http://audio.oxforddictionaries.com/en/mp3/crossword_gb_1_8.mp3\">http://audio.oxforddictionaries.com/en/mp3/crossword_gb_1_8.mp3</a>",
When you do that, it'll parse fine.
There is an online JSON to C# class converter I use: json2csharp - generate c# classes from json[^] which gives me these classes:
public class GrammaticalFeature
{
public string text { get; set; }
public string type { get; set; }
}
public class Example
{
public string text { get; set; }
}
public class Sens
{
public List<string> definitions { get; set; }
public List<string> domains { get; set; }
public List<Example> examples { get; set; }
public string id { get; set; }
public List<string> short_definitions { get; set; }
}
public class VariantForm
{
public string text { get; set; }
}
public class Entry
{
public List<string> etymologies { get; set; }
public List<GrammaticalFeature> grammaticalFeatures { get; set; }
public string homographNumber { get; set; }
public List<Sens> senses { get; set; }
public List<VariantForm> variantForms { get; set; }
}
public class Pronunciation
{
public string audioFile { get; set; }
public List<string> dialects { get; set; }
public string phoneticNotation { get; set; }
public string phoneticSpelling { get; set; }
}
public class RootObject
{
public List<Entry> entries { get; set; }
public string language { get; set; }
public string lexicalCategory { get; set; }
public List<Pronunciation> pronunciations { get; set; }
public string text { get; set; }
}Add those to your app, and try Newtonsoft JSOn parser - it should be a single line of code! Json.NET - Newtonsoft[^]
Give it a try - it normally works very nicely for me!

It's probably the "audiofile" entry - it's still got spurious double quotes:
"audioFile": "<a href="http:// ... .mp3">http:// ... .mp3</a>",
^ ^They terminate the string as far as JSON is concerned an need to be escaped.
I'd suggest a simple regex?

If it helps, this works for me with your data:
string jsonText = File.ReadAllText(@"D:\Test Data\Crossword.json");
Regex regex = new Regex("(\"<a href=\"http://)(.*?)(\">)", RegexOptions.Multiline | RegexOptions.CultureInvariant | RegexOptions.Compiled);
jsonText = regex.Replace(jsonText, "\"<a href=\\\"http://$2\\\">");
RootObject ro = JsonConvert.DeserializeObject<RootObject>(jsonText);

I think you need to look closely at exactly the JSON you are processing - it may have other faults!
How different is it to the samples you have been giving?

That is what's so strange, I put the same data you used into a file and copied your code - no error but null properties

Success !!! - thanks very much - what a mess Json is when you start dealing with arrays - the code is truly horrible just to get a single value, if it wasn't for JsonConvert.DeserializeObject and the cool class generator I wouldn't bother with it - thanks once again - do I need to flag this a success ? I've never used this forum before only the Q&A <groan> where you accept the answer

You're welcome!
I quite like JSON - provided you are working with the same classes in the source and destination it works pretty seamlessly. I prefer it to XML which is pretty nasty to parse manually when it doesn't work... 
No, there is no "accept" in the forums, they are just like the Lounge!

Just remembered a not so well known trick in VS, if you create an empty file and paste special from the Edit menu ( with json or xml in the clipboard ), you have the option of pasting json or xml which creates classes for you ( like your online site does ) very useful - just sayin
