Get FQDN using C# bypassing alias in hosts file

In a domain environment i have several clients which reference a server via an alias in the local hosts file. I need to obtain the real hostname of the server. When using Net.Dns.GetHostEntry or Net.Dns.Resolve only the alias name from the hosts file is returned.
var addr = System.Net.Dns.GetHostAddresses("FileServer")[0]; // assume at least one entry
var fqdn = System.Net.Dns.GetHostEntry(addr).HostName;
The reverse lookup using NSLOOKUP works as expected. Is it possible to force the Dns methods to ignore the hosts file?

You can do this calling NSLOOKUP on C#
Here is a method for c#.
/// <summary>
/// Get HostName from IPv4
/// </summary>
/// <param name="ipv4"></param>
/// <returns></returns>
public static string NslookupIP(string ipv4, string dnsServerIpv4)
{
if (IPAddress.TryParse(ipv4, out IPAddress ipaddress))
{
if (ipaddress.AddressFamily != AddressFamily.InterNetwork)
{
throw new Exception("ipv4 is no a valid IPv4");
}
}
else
{
throw new Exception("ipv4 is no a valid IPv4");
}
Process pProcess = new Process();
pProcess.StartInfo.FileName = "nslookup";
pProcess.StartInfo.Arguments = $"{ipv4}";
pProcess.StartInfo.UseShellExecute = false;
pProcess.StartInfo.RedirectStandardOutput = true;
pProcess.StartInfo.CreateNoWindow = true;
pProcess.Start();
string cmdOutput = pProcess.StandardOutput.ReadToEnd();
string pattern = #"^Name:\s*(?<host>(.*))$";
foreach (Match m in Regex.Matches(cmdOutput, pattern, RegexOptions.IgnoreCase | RegexOptions.Multiline))
{
return m.Groups["host"].Value;
}
return "";
}

C# Dynamic Assembly with assembly information

In my code, I create a DLL dynamically. The following code is what I use to create my DLL:
/// <summary>
/// See CodeDom example hon how its used
/// </summary>
/// <param name="source_code"></param>
/// <param name="assemblies"></param>
/// <param name="generate_executable"></param>
/// <param name="compiler_options"></param>
/// <param name="output"></param>
/// <returns></returns>
public static Tuple<Assembly, string> CompileSource(string source_code, List<string> assemblies, bool generate_executable = false, string compiler_options = "/optimize", string output_assembly = "")
{
CompilerParameters compilerParams = null;
CSharpCodeProvider provider = null;
CompilerResults result = null;
string errors = string.Empty;
try
{
provider = new CSharpCodeProvider();
compilerParams = new CompilerParameters();
foreach (var entry in assemblies)
{
compilerParams.ReferencedAssemblies.Add(entry);
}
if (output_assembly != string.Empty)
compilerParams.OutputAssembly = output_assembly;
compilerParams.GenerateExecutable = generate_executable;
compilerParams.GenerateInMemory = false;
compilerParams.IncludeDebugInformation = true;
compilerParams.CompilerOptions = compiler_options;
result = provider.CompileAssemblyFromSource(compilerParams, source_code);
foreach (CompilerError error in result.Errors)
{
errors += String.Format("{0}({1},{2}: error {3}: {4}", error.FileName, error.Line, error.Column, error.ErrorNumber, error.ErrorText);
}
}
catch (Exception err)
{
}
return Tuple.Create(result.CompiledAssembly, errors);
}
What I would like to do is add Assembly Information like the company, product, title, etc.
Looking at this site and site to add it but I'm not sure how to do it.
The CompilerParameters doesn't seem to give an option to add these attributes.
Anyone have a suggestion if it can be done on how to add this information?
Thanks

Windows Azure Pack Authentication Using Node.js

According to your WCF code, seems that this sample used the windows authentication. If you wanna use node.js to achieve to this result, you maybe need to use the passport.js(https://github.com/auth0/passport-windowsauth) implement the windows authentication.
Also, you can use other idp to authentication your application. Please refer to the official document :https://msdn.microsoft.com/en-us/library/dn508295.aspx

I can able to get the proper OCR output using newly trained tessedata (version 3.02) through command prompt but I want same output in C# code with DLL ref.I have tried with tessnet2_32.dll reference but It is throwing exception so How to use or access the tesseract 3.02 version trained tessedata using DLL reference through C# code?

To access or use tesseract 3.02 trained data we have to create separate wrapper class like below.
using System;
using System.IO;
using System.Diagnostics;
using System.Drawing;

outpath = System.Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\out.txt";

string ret = "";

string content = r.ReadToEnd();
ret = content;
}
File.Delete(outpath);
return ret;
}
public string OCRFromBitmap(Bitmap bmp,string lang,bool noLine)
{
bmp.Save(tmppath, System.Drawing.Imaging.ImageFormat.Tiff);
string ret = analyze(tmppath,lang,noLine);
File.Delete(tmppath);

Retrieve Access Information Google gdata-api C#

I am attempting to retrieve the most recent date that my users have logged into any Google app service such as Gmail (or had this done for them via mobile device/imap/pop etc). I am an administrator of the domain on Google apps for Education and using the C# gdata-api.
I would like to recycle student usernames if they have been gone for longer than a year without signing into their gmail apps and require the last accessed date to accomplish this.
Please let me know if this is possible
Thank you.

I used the gmail reporting API. I forget where I got this from but I stole it from somewhere. If you know where, please put a comment link.
