Im trying to send data from a Windows Form to an aspx page and send back a response. Im running around in circles trying to make this work. The data im trying to send is 4 strings. So fare I have this in my code, using the build-in webclient in visual studio 2010, in the windows form sending to the aspx
I have to query once an hour to a remote web server to recieve data. However the remote web site does not use web services and state in thier 300+ page document that:
Although SOAP is a recognized Web Services API, the RTO web server does not offer a web services interface. That is, there is no Web Services Description Language (WSDL) file available for usage by participant web services client software.
So my question is how do send a soap request and get a response without the use of a WSDL?
How do I send/Receive SOAP messages usiung .NET I wanted to invoke a webservice, however not like the way shown in the link above.What I did was, created a service reference with the wsdl url(in a windows application with a button click event)
have created a client object
Dim objProxy As MyClient = New MyClient()
I have populated the objrequest and objreqheader using the below methods, (assigning string values and not xml)
From reference vb, this is the myoperation public function
Public Function myoperation(ByVal RequestHeader As AFA.RequestHeaderType, ByVal GetTransactionDetailsReq As AFA.GetTransactionDetailsReqType, <System.Runtime.InteropServices.OutAttribute()> ByRef GetTransactionDetailsResp As AFA.GetTransactionDetailsRespType) As AFA.ResponseHeaderType
I checked the property of objProxy, it is having basic http binding as the property. Anyone invoked the service like this? From soapui, the response is fine, after i populate the request fields.How can i enable the trace to see what is the request going and where is the problem.
Take the tripservice wsdl from this link In this wsdl, I replaced the from element with the below(added nillable as true and added min length and max length restriction).
The element from xsi:nil="true" is generated, even though i am not touching the element in my vb.net code to generate the request. The element is optional as per the wsdl(min occurs = 0). How can i send a request without the from element name, even passed in the request?
I'm building a .NET component that will call an external web service. I used the "Add Service Reference" dialog to add the web service to my component, which generates the code needed to consume the service and adds the settings to the app.config file.I'm testing the component by adding a reference to its DLL from a Console application and calling the appropriate method that creates a new instance of the web service: ... = new MyServiceSoapClient(). However, when I do this, I get the following exception:
Could not find default endpoint element that references contract 'MyServicesSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.This makes sense since the app.config isn't being brought over with the component's DLL. How can I call the web service without having to rely on the settings in the App.Config?
I have a specific problem that I have not yet found an answer to. Basically I need to pass a list of numbers into a function do some math and return them. I can pass one number at a time without a problem, however when I want to pass in an array I start to have issues. My VB.net code looks like this...
I need to query a web service that basic authentication, putting the username and password in the request header. My client is written in VB.NET Visual Basic Express Edition 2010. I've added the web service to the Service References. It has auto-generated the appropriate classes for me. [code]...
I'm currently working on a VB. Net web service calling another web service running in the mainframe. I was provided with the WSDL file and I generated a proxy class using wsdl.exe. Upon attempting to invoke the method of the mainframe web service using the proxy class, I encountered an exception saying "Conversion from SOAP failed" coming from a line of code in the generated proxy class.
This is my first time using SOAP with anything. I have an interesting situation, I have to send query's via soap to a secure server and get a response back and then import the response into a database. I have the connection to the secure server figured out and importing the returned xml figured out. I followed examples however I get nothing back in the service windows from the remote web site.
Here is my vb.net code with the soap request inside: Imports System.Net Imports System.Security.Cryptography.X509Certificates Imports System.IO Imports System Imports System.Text Imports System.Data [Code] .....
Can anyone help on how to show a message box showing that existing record has been entered in database if i tried to enter the new record. However, if the input is new record (record added), the record is saved into the database. I'm using visual basic 2008 and Microsoft access for database.
I wrote a soap service in PHP using nusoap. It works fine with the test client I wrote in PHP, however, our customer wrote his client in vb.net and it is not working. There are no errors that I see, but the service is not parsing his requests properly.
I am letting nusoap generate the WSDL, and it looks fine. If I compare a message that I send in to one of his messages, I do see a few differences in the envelope, but I'm not sure if the problem is on my end or his.
I have created a self hosted service with a proxy Service and Contracts
Namespace ECDBDatabase.Service Public Class DatabaseService <ServiceContract(Name:="DatabaseService", Namespace:="net.tcp://localhost:9010/ECDBDatabase.Service")> _ Public Interface IRPMSDatabaseService <OperationContract()> _ Function GetHandover(ByVal Username As String, ByVal Password As String) As DataSet End Interface

I'm working on a tcp/ip project for the company i working for, with another company, we are building the server side and they're building the client side. while can send thousands of tcp/ip request over the net from one computer to another and my server can handle them very easily, from some reason when the company we are work with send a single tcp/ip request to my server with their client application, my server do get the request correctly and handle it very well BUT, after one request my server takes 25% of the cpu usage, after 3-4 requests the server takes 100% of the cpu usage,
I'm building a web service to accept notifications from a company. The company informed me that the service is incorrectly structured and provided me the .asmx of a working web service. It looks like this:
Request format is unrecognized for URL unexpectedly ending Error I have 3 webservices on windows 2003 server. All worked fine before and are called from one .net application on another server. Recently I added a few new webservice calls, builded and published . All webservices works fine on development locally. On production server all stopped working.
I would like to know how to solve the problem and how to capture the failure of webservice call. The application that is calling those webservices starts new thread to process and shows user Thanks you will get an email. However webservices stopped working and it took couple days to learn that nothing is happening, after research I learned that webservices do not work anymore. Bummer, I do not know how to alert in this case.But first more important how to fix it. On development server in VS 2005 all webservices works perfect. After publishing and testing on server to Invoke a service, the Error ....unexpectedly ending.. appears. After reading many happy postings that modifying Web.config node protocols, I discovered that instead of
i hav got a problemo with my client/server application that i created in vb.net.Actually i want to add a "Refresh button" at the client side such that when it is pressed some specific lines should be executed at the server side.(e.g. when the "refresh button" is pressed at the client side, the server should evaluate some variable "data" and executes this line "winsock.sendData(data)" )
I am trying to send a POST request to add some content to an API box. The rules are that the body format should be XML(values must be XML-escaped), HTTP Method (post), requires authentication(yes), request content(content-type: "application/xml". [code] Best practice is to incrementally add and remove changes to your entry list instead of deleting/recreating the entire list each time a change is necessary.New entries are placed at the top of the queue for polling and are processed in a LIFO manner.
I have a very long running task I need to take from my website and put into a web service however every time I try call the web service I get this error message The request failed with HTTP status 401: Unauthorized.
I have two web servers with public IPs, for example Server1 with IP 220.127.116.11 and Server2 with IP 18.104.22.168. see the picture:
There is an asp.net webform at Server 1. My intention is:
For every http request to that webform in Server1, the Server1 just pass the request's information to Server2 for logic processing and subsequently Server2 sends the response back to client (i.e. normal browser)
My questions are:
What information that Server1 needs to pass to Server2, so that Server2 able to send response back to client? note that at Server2, there is a TcpListener instance. This TcpListener instance acting as receiver for that webform request information from Server1. What is the suitable object (i.e. the class in System.Net or related namespace such as System.Net.Sockets) at Server2 for sending response back to client? Suitable here means able to meet my intention.
