I have problems finding the correct forum for this question, but hope this will get me there. I have converted a C# Windows Forms project to VB. The project connects to a java-based webservice within a local network. When running the C# project I receieve 8 rows of data which is placed in a listbox.

From a .NET application, how do I consume a Web Service developed using gSoap c/C++ library? I can create a C/C++ client using gSoap library to consume the web service. But I need to consume it from within a .NET (C#) application. I tried Adding a Web Reference but that doesn't seem to work. Would I need to work with raw Soap Packets?
View 2 RepliesHow 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)
objreqheader.id = "abcd"
Finally the below line invokes the service
objresponsehead = objProxy.myoperation(objreqheader, objrequest, objresp)
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.
I have a vb.net baseclass in a dll in my c# project. I created a derived class in c#. I fill the C# class with all its properties, including the base properties from the vb class. Now I send them through a webservice (c# ) to a jQuery client. But on the client I only see the vb properties?
public class FilmItem : ContentItem // ContentItem is from VB DLL {
public string Zender { get; set; }
public string Jaar { get; set; }
[WebMethod]
public IEnumerable GetContentItems(VBLib.GridRequest gridRequest) {
ContentCache contentCache = new ContentCache();
return contentCache.GetFilms(gridRequest); // gives back a List<FilmItem>
}
Just found out that if I remove the vb.net class, all the properties are showing fine from the C# class. Also found out that the vb.net is declared like this:
Public Class ContentItem
Inherits System.Collections.Generic.Dictionary(Of String, Object)
Implements IContentItem
Could it be the dictionary or the interface? (Which sums up the properties I was seeing).
I have written a vb.net app that runs in multiple hospital networks. THe vb client periodically contacts a off-site webservice for datatransfers.The issue I am getting at a particular hospital is that the client PC's are not on the hospital's domain. So they are sort of off the radar. They do use the hospital network for internet access. When the user opens a web browser they are asked for domain
userid and password. If not are provided then they cannot proceed. What do I need to do with my vb.net code to make the webserver calls prompt for and use the proper domain user id and password?
I have web service on server! This service is calling from the clients applications!Now how i can get user name and computer name of clients that using this service, for example if application from Clint1 calling this service i want to get computer name and user name of Clint1?
View 3 RepliesI am building a client in VB.net for calling webservices methods from a partner organisation.[URL]../system.web.services.protocols.soaphttpclientprotocol%28v=VS.71%29.aspx because I can't get it to work using the Web References feature of Visual Studio 2010 (when I try to do that it turns the methods from the WSDL into classes).I have created a proxy class and can instantiate an object of that class no problem.
However, when I try to call a method which requires arguments I get this error:
Unmarshalling Error: unexpected element (uri:"http://api.service.apimember.emailvision.com/", local:"key"). Expected elements are <{}key>,<{}login>,<{}pwd> Does anyone have any idea why this might be? (If it's helpful I can post my code and the location of the WSDL.) (P.S. I can get the whole thing to work fine in PHP using ZF Soap classes, but for various reasons I need to get it to work using .Net)
Edit to add: I have used Wireshark to examine the outgoing and incoming SOAP message to compare them with the messages being sent via SoapUI, where it all works fine.What this has shown is that my VB client is sending a message where the namespace of the web service I am trying to access is declared as an attribute of the method, and not in the soap:envelope attributes.

I'm developing a application and it contain server and client. Whenever client application or client gets any error or exception, error message should writes to error.log file placed in Server. Assume there is no shared driver or there is no any way of entering server credential user name and password. I have done a testing with listening socket and once application convert as Windows Service, it does not work anymore. But as UI it work fine.
View 8 RepliesI have a 3rd party webservice (happens to be a peoplesoft EIP service) that I'm trying to call from .net. I've tried using a service reference and the old web reference to call this service and every time I call it I get a response of "nothing" back from the service.
I've ran the service call through SoapUI and it works fine. I've captured the network traffic using Fiddler and notice that when i call the service from SoapUi or from .Net I get the same resulting xml back from the call. So that means the call is working. I've turned on tracing and logging within WCF and I'm not seeing any errors. Nor is it throwing an exception.
So my theory is that .net is having a hard time translating the xml from the service back into a .net object.
Here is a snippet of my code:

O_O How can this be returned? Is this normal? Is this possible? How can the request have originated from localhost (127.0.0.1) and at the same time from a remote IP-address? Was the server hacked?

I have a .net application that uses customerrors web.config module to display meaningful messages for errors. It works without any issues for 500 errors/exceptions caused by non-ajax and ajax components (updatepanel). However, in a scenario where updatepanel's asynchronous request times out, there is no error raised at all. I was able to see the timeout in firebug and come up with a solution that would at least display the error message as an alert and then redirect the user to the 500 error page using javascript but it's not quite doing what the rest of the application does in case of an unhandled errors like these. I basically just want everything to go through "LogEvent" mechanism so based on the severity of the error, it does the necessary work.This 500 error page doesn't have anything in the Server.GetLastError() for these timeout scenarios. Is this an expected behaviour? Can it be changed so I do have access to these timeouts in Server.GetLastError() OR maybe just run this error through "LogEvent" mechanism? Is there a better/more graceful way to handle this issue?
Below is my code to give you an idea, not exactly what I have in my application but pretty close.
Web.Config
<customErrors mode="On" defaultRedirect="~/Errors/ErrorUnknown.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="~/Errors/Error500.aspx" />

I have been reading through Atheists posts in regards to client-server and TCP client/server connection's. But how do i go about writing a program with 1 client and server where the client side creates a text file.Once the server sees there is a text file it connects and downloads it to itself or the client pushes the text file to the server.Once on the server i will read the text file and put its info into a sql db.
View 14 RepliesI have an application that takes a series of reports and sends them as attachments in an email to a specified group of email accounts.
When I run the Java version of this using apache commons and the same setting, the email is sent. However, when I run the VB.NET version of the code, it fails on my local machine and on the client machine.
I have a VB.NET web application running on a server that uses similar code. I tried that code locally and it fails. Yet, the web application is working perfectly.
Why is it that the Java application can send the email, but the .NET application cannot?[code]....

Im using the code from [URL] as a starter, most of the code is the same. the chat system works fine but on the client a added a disconnect button "clientSocket.Close()" and as soon as i click that i get errors, on the client, this is the code...

And this line...
serverStream.Read(inStream, 0, buffSize)
gives me "Unable to read data from the transport connection: A blocking operation was interrupted by a call to WSACancelBlockingCall."
Now im talking the server, after the client clicks disconnect or closes by task manager, looses connection, etc the server crashes and gives me.

this is probably easier than I think it is.I would like a client-to-client messenging system without using Winsock if possible. At the moment an IP based connection system would be okay.
View 8 RepliesCan't find any free ones so thought I would work on one on my own for the heck of the learning experience with TCP stuff.I'm about ready to start on the messaging aspect of it.The biggest thing I'm wondering about is figuring out when people are online.I'm not too sure how the whole thing works.Say I turn on my messenger. Would my messenger just send a message to all IPs on a certain port to say I'm online and then wait for a message back from the IPs that can return messages and then figure out who is online that way?

we had developed a webservice in vb.net,framework 2.0. We would need to rewrite this websevice in WCF with framework 3.5. Please provide some guidance regarding this and also there are many othersystems consuming our webservice url. Will this conversion have impact on the source system or does it involve any build activity for the source system to consume the url that will be developed with WCF method?

View 14 Repliesi have been working on a chat program Server side and client side i have most of the features i was asked to put in but then once i got most of the bugs out i noticed something the server admin could send whispers and alerts to single users but then when you try do do it on the client side it wont work so i looked through it all and found my issue the user list on the client is only a list of the names in server hash table so i was wondering how do i send the hashtable and all of its data E.G. user connection information to the client so that it can send commands to individual users like the server side can
vb
Public clients As New Hashtable()
' This subroutine checks to see if username already exists in the clients
' Hashtable. If it does, send a REFUSE message, otherwise confirm with a JOIN.

i tried to send the hashtable over the same method used to send the user names to the client but it cannot convert the hashtable to a string so that wont work so my question is How do i send the hash table to the user from the server then display the username on the client ??
I have a search engine that will use a webservice to search through my database to find 3 specific things. I don't even know if it will work like this, but I have a dropdown list on my main page to select Product, Feature, Description. From what the user selects, the webservice should then go to an if statement to use the correct SELECT statement and find results for the search.
Will someone help me figure out how to fix what I've written to make it work? Please don't be too critical, I don't have a lot of experience. I have also been researching SQL Injection because I have a lot of code that is vulnerable so keep that in mind when you look at my code.
