Coinspot REST API - C#

I'm trying to hit the Coinspot REST API, but I'm getting an error returned. I'm having no trouble talking to Bittrex and Independent Reserve, but Coinspot is a bit different. This is my code:
protected override RESTClient RESTClient { get; } = new RESTClient(new NewtonsoftSerializationAdapter(), new Uri("https://www.coinspot.com.au/api"));
public class postdata
{
public string nonce { get; set; }
}
public string CalculateMD5Hash(string input)
{
//step 1, calculate MD5 hash from input
MD5 md5 = MD5.Create();
var inputBytes = Encoding.ASCII.GetBytes(input);
var hash = md5.ComputeHash(inputBytes);
// step 2, convert byte array to hex string
var sb = new StringBuilder();
for (int i = 0; i < hash.Length; i++)
{
sb.Append(hash[i].ToString("X2"));
}
return sb.ToString();
}

var nonce = APIHelpers.GetNonce();
var postdata = new postdata { nonce = nonce };
var json = JsonConvert.SerializeObject(postdata);
System.Diagnostics.Debug.WriteLine(json);
var sign = APIHelpers.GetHMACSHAHash(ApiSecret, json, APIHelpers.HMACSHAType.NineBit);
//Do we do this?
//The JavaScript samples seem to hash with MD5 afterwards for double encryption?
sign = CalculateMD5Hash(sign);
RESTClient.Headers.Clear();
RESTClient.Headers.Add("sign", sign);
RESTClient.Headers.Add("key", ApiKey);
try
{
var retVal = await RESTClient.PostAsync<string, postdata>(postdata, "/my/balances");
System.Diagnostics.Debug.WriteLine(retVal);
}
catch (Exception ex)

}
throw new NotImplementedException();
}
The doco is very scant! I'm stuck.

I don't have the error handy right now, but it was a completely non-descript error with information about what went wrong. It was something like "invalid call". But, I know that it is accepted my posted data to some extent, because if I change the name of the property "nonce" to "noncey", I get a meaningful error back that says "no nonce".

Did you ever manage to get this API working. CoinSpot are not very supportive of this. I can only get 3 of the coins API working which isn't much help

I managed to get it working recently and put together a simple SDK in .NET
https://github.com/QuintinHumphreys/CoinspotAPI

tl:dr It's undocumented but you need to use port 443, I found it by digging through their node SDK.
I was having the same issue, getting the very non-descriptive {status: invalid} response, in my case using Elixir not C#. I got it to work by peeking into their node SDK - my details worked using their SDK so I knew it had to be something I wasn't doing properly (although their documentation is pretty shocking). They use port 443 and as soon as I set that it worked.
I tried 2 things, I'm 90% sure it was the port number but half way through my getting it to work I printed the sha512 sign created by their node sdk and compared it to the one I generating using Cryptex I saw that they were generating the same sha512 signature, but my one was in capital letters while the node one was in lowercase - this may or may not end up mattering but I did use String.downcase() on mine in the end.

So the issue im having is when i try to run the program i get an error at this line
sbasedrmTableAdapter.Insert(drm_key_id);
and the error i receive is:
Error CS7036 There is no argument given that corresponds to the
required formal parameter 'drm_key' of
'sbase_drm_keysTableAdapter.Insert(string, string, string, string)'
How can i solve this error

It looks like you are trying to call a method that requires 4 strings as parameters with just one parameter. Try supplying the correct parameters to the method.
Your problem looks quite similar to: OOP inheritance and default constructor

C# ConsoleRead() input not saved in variable

I am working with C# for the first time and I am facing a strange issue.
I am building my own class for a plugin, but copied parts of the code from an existing class. Basically it's
var sanInput = Console.ReadLine();
alternativeNames = sanInput.Split(',');
sanList = new List<string>(alternativeNames);
but somehow this doesn't work. The debug console says System.Console.ReadLine returned jogi,philipp string, but sanInput keeps null as its value.
Even stranger is the fact, that the next step works "a bit". string.Split returned {string[2]} string[], so it returns an array of [jogi, philipp], but still sanInput, alternativeNamesand sanList stay as null.
How is it possible, that the second line works if sanInput has no value and how can I fix this problem? When I work with the existing class with the same code everything works as expected.
//EDIT:
Looks like a quite complicated issue. Here is the complete method:
public override void HandleMenuResponse(string response, List<Target> targets)
{
if (response == "r")
{
Console.WriteLine("Which hosts do you want to configure? Enter numbers separated by a comma.");
var hostsInput = Console.ReadLine();
int[] hosts = null;
string[] alternativeNames = null;
List<string> sanList = null;
hosts = hostsInput.Split(',').Select(int.Parse).ToArray();
Console.Write("Generating certificates for ");
foreach (int entry in hosts)
{
Console.Write(targets[entry - 1].Host + ", ");
}
Console.Write("\n \n");
foreach (int entry in hosts)
{
int entry2 = entry - 1;
if (Program.Options.San)
{
Console.WriteLine("Enter all Alternative Names for " + targets[entry2].Host + " seperated by a comma:");
// Copied from http://stackoverflow.com/a/16638000
int BufferSize = 16384;
Stream inputStream = Console.OpenStandardInput(BufferSize);
Console.SetIn(new StreamReader(inputStream, Console.InputEncoding, false, BufferSize));
var sanInput = Console.ReadLine();
alternativeNames = sanInput.Split(',');
sanList = new List<string>(alternativeNames);
targets[entry2].AlternativeNames.AddRange(sanList);
}
Auto(targets[entry - 1]);
}
}
if (response == "e")
{
string[] alternativeNames = null;
List<string> sanList = new List<string>();
if (Program.Options.San)
{
Console.WriteLine("Enter all Alternative Names seperated by a comma:");
// Copied from http://stackoverflow.com/a/16638000
int BufferSize = 16384;
Stream inputStream = Console.OpenStandardInput(BufferSize);
Console.SetIn(new StreamReader(inputStream, Console.InputEncoding, false, BufferSize));
var sanInput = Console.ReadLine();
alternativeNames = sanInput.Split(',');
}
if (alternativeNames != null)
{
sanList = new List<string>(alternativeNames);
}
foreach (var entry in targets)
{
Auto(entry);
}
}
}
I know the code isn't pretty and efficient. All in all it let's the user decide if he wants to use all detected hosts (response e) or only single ones (response r). But the mentioned problem occurs only in the second if-method. If I switch them it's again the latter one. So maybe the reason lies in the main program or in this BufferSize-Stuff? I don't know.
//EDIT 2: I think I found the problem: Somehow the integer BufferSize (shortly before the Console.Read()) is set to 0, so of course without any buffer it can't read the input. So the question remains: Why?
//EDIT 3: Okay, I'm done. It looks like I can't use the same name for the variables although they are in two different if-methods. I just named them sanInput2, alternativeNames2 etc. and now everything works.

try this, all of the variables are having values(you can use var also for all the variables):
var sanInput = Console.ReadLine();
string[] alternativeNames = sanInput.Split(',');
List<string> sanList = new List<string>(alternativeNames);

The problem you mention is, that debugging code in VS do assignements in two steps. First is to execute Console.ReadLine() (therefore you see Console.Readline returned message) and AFTER that is is assigned into sanInput. Same situation is after Split. Function is called, but not assigned yet.
My recommendation: use rather the step over instead of step inside. After time, you get used to this functionality and appreciate it.

ServiceNow - Getting all records

In ServiceNow, I am able to get only a maximum of 250 records in a SOAP request. How to get all the records?
Web Reference Url = https://*****.service-now.com/rm_story.do?WSDL
Code:
var url = "https://*****.service-now.com/rm_story.do?SOAP";
var userName = *****;
var password = *****;
var proxy = new ServiceNow_rm_story
{
Url = url,
Credentials = new NetworkCredential(userName, password)
};
try
{
var objRecord = new Namespace.WebReference.getRecords
{
// filters..
};
var recordResults = proxy.getRecords(objRecord);
}
catch (Exception ex)
{
}
In recordResults, I am getting only 250 records. How to get all the records ?

Also see this stack overflow answer which provides info.
Get ServiceNow Records Powershell - More than 250
Note that returning a large number of records can affect performance of the response and it may be more efficient to process your query in batches using offsets (i.e., get 1-100, then 101-200, ...). This can be achieved by using a sort order and offset. The ServiceNow REST Table API actually returns link headers from Get requests providing you links for the first, next and last set of records making it easy to know the url to query the next batch of records.
See: http://wiki.servicenow.com/index.php?title=Table_API#Methods
and look under 'Response Header'.

Have u tried to pass/override __limit parameter?
Google / wiki / Users manual / Release notes are always helpful

In your code snippet in line where it says //filter you should define __limit (and potentially __first_row and __last_row as explained in the example bellow)
int Skip = 0;
int Take = 250;
while (true)
{
using (var soapClient = new ServiceNowLocations.ServiceNow_cmn_location())
{
var cred = new System.Net.NetworkCredential(_user, _pass);
soapClient.Credentials = cred;
soapClient.Url = _apiUrl + "cmn_location.do?SOAP";
var getParams = new ServiceNowLocations.getRecords()
{
__first_row = Skip.ToString(),
__last_row = (Skip + Take).ToString(),
__limit = Take.ToString()
};
var records = soapClient.getRecords(getParams);
if (records != null)
{
if (records.Count() == 0)
{
break;
}
Skip += records.Count();
if (records.Count() != Take)
{
// last batch or everything in first batch
break;
}
}
else
{
// service now web service endpoint not configured correctly
break;
}
}
}

I made an library that handles interacting with ServiceNow Rest API much easier

C# Inserting a new Requirement in HP Quality Center - AccessViolationException

Trying to create a prototype application that will post a new Requirement to HPQC 11.
I've managed to get a solid connection but when I attempt to add the blank requirement I get an AccessViolationException.
TDConnectionClass td = HPQC_Connect(); //Open a connection
ReqFactory myReqFactory = (ReqFactory)td.ReqFactory; //Start up the Requirments Factory.
Req myReq = (Req)myReqFactory.AddItem(DBNull.Value); //Create a new blank requirement (AccessViolationException)
myReq.Name = "New Requirement"; //Populate Name
myReq.TypeId = "1"; // Populate Type: 0=Business, 1=Folder, 2=Functional, 3=Group, 4=Testing
myReq.ParentId = 0; // Populate Parent ID
myReq.Post(); // Submit
Any ideas? I'm fairly new to C# and coding in general, so it's probably best to assume I know nothing.

After some significant working through the isse the following code works correctly:
private void HPQC_Req_Create_Click()
{
TDConnection td = null;
try
{
td = new TDConnection();
td.InitConnectionEx("server");
td.Login(HPQCUIDTextbox.Text.ToString(), HPQCPassTextbox.Text.ToString());
Console.WriteLine(HPQCPassTextbox.Text.ToString());
td.Connect("DEFAULT", "Test_Automation_Playground");
bool check = td.LoggedIn;
if (check == true)
{
Console.WriteLine("Connected.");
HPQCStatus.Text = "Connected.";
}
ReqFactory myReqFactory = (ReqFactory)td.ReqFactory;
Req myReq = (Req)myReqFactory.AddItem(-1); //Error Here
myReq.Name = "New Requirement 1";
myReq.TypeId = "1"; // 0=Business, 1=Folder, 2=Functional, 3=group, 4=testing
myReq.ParentId = 0;
myReq.Post();
Console.WriteLine("Requirement Created.");
HPQCStatus.Text = "Requirement Created.";
try
{
td.Logout();
td.Disconnect();
td = null;
}
catch
{ }
}
catch (Exception ex)
{
Console.WriteLine("[Error] " + ex);
try
{
td.Logout();
td.Disconnect();
td = null;
}
catch
{ }
}
This code requires that the Server be patched to QC 11 Patch 9 (Build 11.0.0.7274) in order to work. Previous versions cause errors, most notably the error in the question.

Requirements in ALM are hierarchical, when creating requirement you need to create it under some existing requirement.
What you want to do is get a hold of the root requirement, it's Id should be either 0 or 1, you can check it in ALM UI.
And then get an instance of ReqFactory from a property on that Root requirement.
And then add your requirement to that factory.
Also, make sure you are working on STA and not MTA thread.
