Hello I am trying to catch messages from database and transfer to caller but when I used Clients.Caller method then it pass me error like
Using a Hub instance not created by the HubPipeline is unsupported
If I am using
var context = GlobalHost.ConnectionManager.GetHubContext<ChatHub>();
context.Clients.All.receiver(respose);
then it replying nothing. So please help me to solve out this question.
and I am using below code:
public async Task GetAllMessages(int roomid, int fromuserId, int touserId, int index, int pageSize, int broadcastid = 0)
{
ResponseModel respose = new ResponseModel();
try
{
var model = new MessageDetailModel
{
Index = index,
PageSize = pageSize,
FromUserId = fromuserId,
ToUserId = touserId,
ChatRoomId = roomid,
BroadCastId = broadcastid
};
MesaageModel totalmessages = new MesaageModel();
List<RecentMessage> messages = new List<RecentMessage>();
var usermessages = await _userService.GetAllMessages(model);
messages.AddRange(usermessages);
foreach (var message in messages)
{
model.BroadCastMessageId = model.BroadCastId == 0 ? 0 : message.BroadCastMessageId;
model.ChatRoomMessageId = model.BroadCastId == 0 ? message.ChatRoomMessageId : 0;
List<UserDetail> userofseenby = new List<UserDetail>();
var users = await _userService.GetMessageSeenBy(model);
userofseenby.AddRange(users);
message.SeenBy = userofseenby;
}
//totalmessages.Messages.AddRange(messages);
totalmessages.Messages = messages;
totalmessages.UnseenMessageCount = await _userService.GetUnSeenCount(messages.FirstOrDefault().ChatRoomId, fromuserId);
if (messages.FirstOrDefault().IsBroadCast == true)
totalmessages.Users = (List<UserDetail>)await _userService.GetUsersByBroadCastId(messages.FirstOrDefault().BroadCastId);
else if (messages.FirstOrDefault().IsGroup == true)
totalmessages.Users = (List<UserDetail>)await _userService.GetUsersByChatRoomId((int)messages.FirstOrDefault().ChatRoomId);
respose = ResponseHelper.SuccessResponse("onAllMessagesReceived", totalmessages);
Clients.Caller.receiver(respose); // Error catch here
}
catch (Exception ex)
{
respose.ActionCommand = "onAllMessagesReceived";
respose = ResponseHelper.ErrorResponse(respose.ActionCommand, ex.ToString());
Clients.Caller.receiver(respose);
}
}
And Constructors of class is below :
public ChatHub()
{
_userService = new UserBusinessLogic();
_chatterService = new ChatterBusinessLogic();
}
public ChatHub(IChatterBusinessLogic chatterService, IUserBusinessLogic userService)
{
_chatterService = chatterService;
_userService = userService;
}
And Controller constructor are like this :
public ChatterController()
{
_userService = new UserBusinessLogic();
_chatterService = new ChatterBusinessLogic();
}
public ChatterController(IChatterBusinessLogic chatterService, IUserBusinessLogic userService)
{
_chatterService = chatterService;
_userService = userService;
}

There are only 3 situations for result.
1- Paid
2- waiting for payment
3- blocked
(Think like this is a bank program)
So when I run the code, always says true. Never false. I want it work normally. Need help.

So that's the whole code for odemeKd.
We have one more big code but there is no definition in the other one.
So i hope you can find the answer of this code.
Thank you so much.
How do I solve this terminating with kafka? I have the following error: https://i.stack.imgur.com/bY2j3.png

I'm having trouble converting a Query Expression found here: http://www.oak3.org/crm/workflow-activity-checking-duplicate-instances/
into a linq query. To put it simply, the goal is if two workflows get triggered at the same time, only let one go through sorted by most recent. Currently my linq version will sometimes cancel a workflow even if it is the only one running. I know I need to utilize the input parameter somehow (to tell it what workflow to compare to), and I'm sure there could be more issues. Any help is greatly appreciated.
[Input("Current workflow")]
[ReferenceTarget("workflow")]
public InArgument<EntityReference> workflowReferenceInput { get; set; }
[Output("Is first workflow")]

{
ITracingService tracer = executionContext.GetExtension<ITracingService>();
IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
try
{
Entity entity = (Entity)context.InputParameters["Target"];
isFirstWorkflow.Set(executionContext, false);
var wfReference = workflowReferenceInput.Get(executionContext);
var wfEntity = service.Retrieve("workflow", wfReference.Id, new ColumnSet ( "name" ));
ConditionExpression ce1 = new ConditionExpression();
ce1.AttributeName = "statuscode";
ce1.Operator = ConditionOperator.In;
ce1.Values.Add(0);
ce1.Values.Add(10);

LinkToEntityName = Quote.EntityLogicalName,
LinkFromAttributeName = "regardingobjectid",

};
link.LinkCriteria.AddCondition("quoteid", ConditionOperator.Equal, context.PrimaryEntityId.ToString());
DataCollection<Entity> result = service.RetrieveMultiple(qe).Entities;
var list = result.ToList().OrderBy(c => c.Id);
for (var i = 0; i < list.Count(); i++)
{
var item = list.ElementAt(i);
if(item.Id == context.OperationId && i == 0)
{
isFirstWorkflow.Set(executionContext, true);
}
}
}
catch (Exception e)
{
throw new InvalidPluginExecutionException(e.Message);
}
}
into this:
public class WorkflowChecker: CodeActivity
{
[Input("Current workflow")]
[ReferenceTarget("workflow")]
public InArgument<EntityReference> workflowReferenceInput { get; set; }
[Output("Is first workflow")] public OutArgument<Boolean> isFirstWorkflow { get; set; }
protected override void Execute(CodeActivityContext executionContext)
{
IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
try
{
var ok = WorkflowChecker(context.PrimaryEntityId, context.OperationId);
isFirstWorkflow.Set(executionContext, ok);
}
catch (Exception e)
{
throw new InvalidPluginExecutionException(e.Message);
}
}
}
which calls:
public static bool WorkflowChecker(Guid workflowContextId,
Guid asyncOperationId)
{
var someReturnValue = false;
var listOfWorkflowIds = new List<Guid>();
try
{
var query = from async in AsyncOperationSet
join b in BSet on async.RegardingObjectId.Id equals b.Id
where b.Id.Equals(workflowContextId)
&& (async.StateCode.Equals(0)
|| async.StateCode.Equals(1)
|| async.StateCode.Equals(2))
select new {async.AsyncOperationId};
foreach (var x in query)
{
if (x.AsyncOperationId != Guid.Empty)
{
listOfWorkflowIds.Add(x.AsyncOperationId.Value);
}
}
listOfWorkflowIds.Sort();
if (listOfWorkflowIds.First() == asyncOperationId)
{
someReturnValue = true;
}
}
catch (Exception e)
{
Console.WriteLine("Error in Workflow Checker: " + e);
}
return someReturnValue;
}
I've added the following lines to the workflow library then passed the parameter into the call to compare by name and so far it appears to be working successfully:
var wfReference = workflowReferenceInput.Get(executionContext);
var wfEntity = service.Retrieve("workflow", wfReference.Id, new ColumnSet("name"));
var test = wfEntity["name"];
I used to work with browser-based applications. for example Angular simple repository.
function getSomeData(params) {
...
return $http({
url: conf.urlDev + 'some/rest-url',
method: "GET",
params: params,
cache: true
}).then(getDataComplete);
function getDataComplete(response) {
return response.data;
}
}
How it will look the same in c# (XAMARIN for example)?

};
return error;
}
}
in my service:
public async Task<IList<News>> GetAllNewsByParams(DateTime from,
string orderBy = "-published",
DateTime to = new DateTime(),
int page = 1, int category = 0)
{
_client.Path = _config.NewsPath;
var dict = new Dictionary<string, object> {

{"page", page.ToString()}
};
if (category != 0)
{
dict.Add("category", category.ToString());
}
var res = await _client.getList<News>(dict);
return res.Value;
}
and im ny viewmodel
foreach (var item in await _newsService.GetAllNewsByParams(
_To,
_OrderBy,
_From, _Page,
selectedTag == null ? _SeletedNewsTagId : selectedTag.Id))
{
NewsList.Add(item);
}
Is his query executed synchronously ?
How do I make it an asynchronous?
First of all I would really encourage you to use RestSharp, it really simplifies making HTTP requests and deserialise them. Add a RestSharp nuget package to your project. Here is how your code will look like using RestSharp.
public class BaseClient
{
protected IRestClient _client = null;
protected string _urlObj;
protected string _basePath;
public BaseClient()
{
_client = new RestClient();
}
public async Task<Result<IList<T>>> GetList<T>(string path, Dictionary<string, object> parametrs = null)
{
var request = new RestRequest(path, Method.GET);
if (parametrs != null)
{
foreach (var keyValue in parametrs)
{
request.AddQueryParameter(keyValue.Key, keyValue.Value);
}
}
var response = await _client.Execute<List<T>>(request);
if (response.IsSuccess)
{
return new Result<IList<T>>()
{
Success = true,
Value = response.Data
};
}
else
{
var error = new Result<IList<T>>()
{
Error = response.StatusCode.ToString(),
Message = response.StatusDescription,
Success = false
};
return error;
}
}
}
In your service
public async Task<IList<News>> GetAllNewsByParams(DateTime from,
string orderBy = "-published",
DateTime to = new DateTime(),
int page = 1, int category = 0)
{
var dict = new Dictionary<string, object> {
{"from", from.ToString("s")},
{"order_by", orderBy.ToString()},
{"to", to.ToString("s")},
{"page", page.ToString()}
};
if (category != 0)
{
dict.Add("category", category.ToString());
}
var res = await _client.GetList<News>(_config.NewsPath, dict);
return res.Value;
}
And in your viewmodel
var news = await _newsService.GetAllNewsByParams(
_To,
_OrderBy,
_From, _Page,
selectedTag == null ? _SeletedNewsTagId : selectedTag.Id);
foreach (var item in news)
{
NewsList.Add(item);
}
This will be 100% asynchronous.
I'm looking for a way to send Sms throught MbnApi using :
http://msdn.microsoft.com/en-us/library/windows/desktop/dd323167(v=vs.85).aspx
IMbnSms interface. But it's not working at all.
I could not have a sample project to see how to do it. I'm coding on C# .Net
