Appreciate if anyone could help me to resolve this issue.

I am using DataServiceContext to get data from SQL DB using WCF service and Connection string and StackTrace is as under as under:

i am curious to know that if i build a web service with legacy asmx technology and host that web service in a pc which is publicly accessible over internet then any mobile client can consume or call asmx based web service ?

because i know Mobile client can consume or call web site.

if the answer is no mean Mobile client can't consume or call asmx based web service then please highlight all the reasons. thanks

On aspx I have this

function ShowCurrentTime() {$.ajax({
        type: "POST",
        url: "JSFireCSharp.aspx/GetCurrentTime",
        data: '{name: "' + $("#<%=txtUserName.ClientID%>")[0].value + '" }',
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: OnSuccess,
        failure: function(response) {
            alert(response.d);
        }
    });
}

Then I have this in code behind

[System.Web.Services.WebMethod]
public static string GetCurrentTime(string name)
{
    return "Hello " + name + Environment.NewLine + "The Current Time is: "+ DateTime.Now.ToString();

(((Here I want to add a line Label1.Text = name but get error))))
}

I want to add a line Label1.Text = name but get error. It seems I am not able to gain access to Label1.
Pls help. What can I do ? Thanks
   

My RESTful API service developed by ASMX. Is there any tool or library we can use to generate API document(API help pages).  Something like this for ASP.NET Web API.

https://docs.microsoft.com/en-us/aspnet/web-api/overview/getting-started-with-aspnet-web-api/creating-api-help-pages

Hi,

We are currently testing our website in Azure.

There are two web servers with one load balancer.

We configured the website and the WCF in both server.

However, the error as the image below appears once a while.

https://ibb.co/k9YkKw

Is there anything we need to set to make it work in the load balancer environment?

It works all the time in our testing server without load balancer.

Thanks.

How to implement WCF Services with token for Authentication?

I have different types of webservices like asmx, WCF and WEB APIs. is there a way to check the status of all those services using powershell scripts and send an email 

I've seen old books about WCF that are from 2010/2011.....

I know that WCF doesnt change so fast....

So  those books still relevant? What differences should I care about ?

thx

anderson

I have a code that works great when I add web reference, and on my code behind all the properties and signatures are all exposed. I can do inserts easily as you can see below

 Dim soap As New ServiceNowRef.ServiceNow_incident
        Dim cred As New System.Net.NetworkCredential("xxx", "xxxxx")
        'Dim soapclient As New We
        Dim msg As String = String.Empty
        Dim insert As New ServiceNowRef.insert
        Dim insertResponse As New ServiceNowRef.insertResponse

        soap.Credentials = cred
        insert.u_ticketnumber1 = Request.Form("ticketnumber1")
        insert.u_ticketnumber2 = Request.Form("ticketnumber2")
        insert.u_ticketstatus = Request.Form("TicketStatus")
        insert.u_ticketstatusnotes = Request.Form("TicketStatusNotes")

        Try
            updateResponse = soap.insert(insert)
            msg = "Incident inserted"
        Catch ex As Exception
            msg = "Incident Not inserted:" & ex.ToString
        End Try

The code requirement has changed and instead of doing through webreference, I need to perform same function like INSERTing a record to an API, the URL & other references should be defined on the same page.
How do I achieve that? Is it possible without adding too much complexity. Can you show me some samples?

Thank You

I am not sure which forum to choose for this.

I have web application developed in visual studio 2015 in c#. This web application is back-end and which runs only in intranet.

We have mobile app as front-end which access some web services written in the back-end app. This front-end mobile app is available on internet. 

So are these web services can be accessible through front-end app without doing anything?

Or how can we make available web services to access through front-end mobile app over internet.

What should we do?

------------------

So far our both back-end and front-end both were on intranet or both were on internet, so was not a problem. Now it's mix of intranet and internet (back-end with web services - intranet, front-end which access web services - internet) , so not sure what we need to change so web services will be accessible over internet. 

Hi,

I have created a wcf service which is called successfuly in  my local app. I have run unit tests . But it is on  my local host and i need to host it so that it can be tested by a testing centre ...

they mention 

The textbox below needs a URI for an API you create and host. It should be your own implementation of our reference service.

the text box has        http://your-hostname/api

I assume the wcf service would be required here or is an ai required ?

I dont have an external host name , can i use github ?

thanks

please explain with example that What is throttling in WCF

I have web application with web services, .asmx page.

I have to publish web application on intranet and I have to publish web service on internet.

So I have to create separate application in IIS having web service, .asmx page only and separate web site for web application.

How to know with .asmx page what else i need to keep in that folder. For e.g. do i need to keep web.config, bin folder and what else?

I have keep same web.config, bin folder in my other web app web site folder also.

-----------------

My application and web service share common folder on server. That folder will be under application web site folder. How can I point my web service to access the same folder as my application?

I have published CMS and web service separately. But CMS and web service share common folders and files.

Folders and files are in CMS published folder. How can I enable my web service to point to those files and folders?

Hello,

we are right now trying to expose a Web Service method to another company. Their demands are that the method is OneWay and we need to have the attribute **elementFormDefault = "Unqualified" **.

We don't fully understand the way this works, we are using VS 2010 and we added a new Item called "Web Service". Then we defined our Web Method and build the solution. Everything worked well and the WSDL generated looks good. The only problem is that we always have elementFormDefault = "Qualified" no matter how we define our class.

We can make the WSDL generated to indicate that all attributes are unqualified but we always have the element for default defined as qualified...

When our client tries to use our method we receive empty information...

our class to generate the XML is this one, note that the class is a bit messy as we tried multiple solutions:

We kinda tried everyhing and we are not able to find a solution for this... everytime our method is being called we dont have nothing in the input parameters... and when the cliend send us the WSDL that they used to send to our method infact the attributes are there. This is the WSDL the client wants to send to us, so our WSDL must accept this:

Can you guys please give us some hint?

Thanks in advance,

VC

I'm trying to develop a Xamarin App (Xam 4.7.10.38 with Xam.And.SDK 8.0.2.1 using PCL approach) connected to an Dynamics 365 Finance And Operation Custom Web Service. Just to sum it up, it's a WCF Soap service that uses Azure Active Directory Client Id + Client Secret to connect to the soap service.  

I've posted the most important part of the code below for reference.  

So as instructed, I used the Silverlight SDK to create the service reference proxy class and also added the necessary framework references. Then I included this proxy class in my Android Project as wel as in a standard .Net Windows App, both using VS.Net 2017.   Everything is identical up until I call "var resultAsync = service.BeginValidateUser(validateUserRequest, null, null);"  

In my Windows App, it returns System.ServiceModel.Channels.ServiceChannel.SendAsyncResult. I do the WaitOne to conclude it and my EndValidateUser returns a correct result.

  However in my Android App, it returns System.Runtime.Remoting.Messaging.AsyncResult which is a different object with different members/methods. The Waitone still works, but when I call the EndValidateUser, I got an exception saying  "System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.\nParameter name: value\n  at (wrapper managed-to-native) System.Object:__icall_wrapper_mono_delegate_end_invoke (object,intptr)\n  at (wrapper delegate-end-invoke) <Module>:end_invoke_object__this___object[]&_IAsyncResult (object[]&,System.IAsyncResult)\n  at System.ServiceModel.MonoInternal.ClientRuntimeChannel.EndProcess (System.Reflection.MethodBase method, System.String operationName, System.Object[] parameters, System.IAsyncResult result) [0x0001f] in <475dec2c1fe44b95bbfbd21b550b63f8>:0 \n  at System.ServiceModel.ClientBase`1+ChannelBase`1[TChannel,T].EndInvoke (System.String methodName, System.Object[] args, System.IAsyncResult result) [0x00045] in <475dec2c1fe44b95bbfbd21b550b63f8>:0 \n  

Any idea's or approaches on how to solve this ?

Hi

I am providing a number of web methods via asmx web service for a mobile app. How does security work in this scenario? Does each web method call need to receive username/password to authenticate each time, or can the authentication for a client app be done only once at the start of client app session?

Thanks

Regards

Hi

icreated WCF service. My project name is SERVICE_ABC. In solution i created Service_A.svc, Service_B.svc, Service_C.svc and PersonelDTO.cs. All service using PersonelDTO.cs. Her is the code

public interface IService_A
{
[OperationContract]
void DoWork();

[OperationContract]
PersonelDTO GetMyData();
}

public interface IService_B
{
[OperationContract]
void DoWork();

[OperationContract]
PersonelDTO GetMyData();
}

public interface IService_C
{
[OperationContract]
void DoWork();

[OperationContract]
PersonelDTO GetMyData();
}

I read service WEB_ABC .net solution. In the HomeController.cs i have got Deneme() controller.  how can i use PersonelDTO  without ServiceReference_A service reference name

public string Deneme()
{
Service_AClient clientA = new Service_AClient();
Service_BClient clientB = new Service_BClient();
Service_CClient clientC = new Service_CClient();

/*Below these codes working properly
var DataA = clientA.GetMyData();
ServiceReference_B.PersonelDTO DataB = clientB.GetMyData();
ServiceReference_C.PersonelDTO DataC = clientC.GetMyData();
*/

//I want to use PersonelDTO without using ServiceReference_A service reference name
PersonelDTO DataA = clientA.GetMyData();
PersonelDTO DataB = clientB.GetMyData();
PersonelDTO DataC = clientC.GetMyData();

return "Ok";
}

Thanks. You can download project this link

I would like to implement a HTTPS connection for my rest webservice. The HTTP version works as well, but when i try to connect over HTTPS and send a XML file or something else, It already fails when establishing the connection via https. Has someone an idea what i can change to test it over https?
