I am developing an ecommerce app that is using the UPS shipping webservice. I have read that it is good to create a singleton so there is only one instance of a webservice at any time. My code for that is below.
Public Class Ship
Private Shared sync As New Object()
Private Shared _Service As New ShipService

How can i list all the available webservices by just providing the server name?I require that i will just specify the server name, and then a list will be populated with names of all the webservices available.
View 2 RepliesNet 3.5 has lots of enhancements on secure and transacted webservices ? Does anyone here have experience of this ? does it add overhead ? Can these webservices (in a LAN environment and assumed stateless / lightweight) be relied upon to be used in realtime (by realtime I mean response of 1 second or less ?). I realise that this cannot be guaranteed as it depends heavilly on what the service is doing and what network it is deployed upon etc etc etc, but assuming there are no issues here, what I am simply asking is, is the benefit of 'knowing' your webservice will return impaired by any overhead that prevent such a webservice from being generally reliable enough to be used in a real time application ?
View 3 RepliesI am a complete newbie when it comes to working with SOAP/Web Services and I am looking for some assitance.... the code below keeps returning the following error message: "A first chance exception of type 'System.Net.WebException' occurred in System.dll"I have utilized SOAPUI to test out the requests to the webservice and everything appears to be fine. What am I missing?
[Code]...
I'm having problems with parsing the XML results that a webservices is sending me. Mostly due to the format this result is sent in. I can succesfully send a request and I get the response back in a string. Now the (truncated) result looks like this:
- <tr>
<td field="fin.trs.line.dim2" hideforuser="false" type="String">01249</td>
<td field="fin.trs.line.openbasevaluesigned" hideforuser="false" type="Value">-100.00</td>
[Code]....
This is where my problem starts. Because I've found various pieces of code that let me take out the nodes I need. So in the above example <Office> and <code> come out perfectly. But the problem appears when reading the other lines because they start with <td SPACE field=> etc etc. When I readout those lines all I get back is TD.
I need to specifically filter the results based on those TR/TD fields. I'm using an XMLreader and xmlnodetype to filter out the results, but maybe I'm using the wrong method.
I've got the unenviable task of cleaning up a rather messy VB.Net client. The general plan is to move all calculations to WebServices, and I can see exactly how to do this, but it involves passing a large number of different variables to the WebServices. I chose to use an ArrayList as I've worked with them heavily in Java, and have had no issues passing ArrayLists between the C# (ASMX) WebService and a C# client (Windows Forms-based).

View 2 RepliesAm pretty new to web services and have been trying to implement Soap Faults. I used Apache Axis2 to generate webservice in the following manner.
[Code]
Now, I created a dynamic project using Eclipse and with the help of Axis2 plugin I created webservice for my "Webservice" class which generates wsdl file. I deployed the webcontent in the Tomcat folder and able to access the WSDL file in the .Net environment. I am able to pass array of objects (User[]) from .Net to Java and able to do my task. Now, I need to implement Soap Faults in Java which I am not sure how to implement.
I am calling Classic ASP Webservices from a .NET application. I have two instances of slow processing of the webservice and fast processing. The slow way (several seconds at the most) is where I actually read the data returned as such:
Dim oRequestAOCP As WebRequest
Dim oResponseAOCP As HttpWebResponse = Nothing
Dim dataStreamAOCP As Stream = Nothing
Dim readerAOCP As StreamReader = Nothing
[code]....
What can I do to speed things up when I need data returned?
When the web service is uploaded to the external server the desktop application has no problem finding and using the web service which access an Oracle DB to send/retrieve information. However, when I go to properties and change the 'Web Reference URL' of the Web Reference to localhost there seems to be a problem with communicating with the DB.

Is there a way in Win App to do a check whether internet is available before connecting to Webservices?

I have worked out how to pass my custom objects into ASP.Net json webservices. Works a charm. Problem I am having is passing in straight arrays of my custom objects or alternatively passing in arrays that are parameters of my custom objects. So for example...
Public Class WebService1
Inherits System.Web.Services.WebService
<WebMethod()> _
[code]....
Fails with error: The value "System.Collections.Generic.Dictionary`2[System.String,System.Object]" is not of type "WebApplication1.WebService1+Person" and cannot be used in this generic collection. Parameter name: value
So how do I explain to ASP.net that it is infact an array of Person? note: That changing the function to as List(of Person) or ArrayList does work but given that I implement my own custom collections this is not optimal for me.
UPDATE: Ok so what I have worked out so far is that this problem is definitely associated with how the JavascriptSerializer uses the SimpleTypeResolver to resolve types. Basically if I do something like this
Public Function AddPersonList(ByVal PersonList As String) As PersonList
I can recreate the error using the following code.
Dim PersonList As PersonList = jsonSerializer.Deserialize(Of PersonList)(PList)
However when I provide my own custom type resolver along the lines of
Dim jsonSerializer As New JavaScriptSerializer(New MyCustomTypeResolver)
I can successfully create an instance of my custom list.Now I have worked out how to provide my own custom convertor in the web.config file. Along the lines of this....
<system.web.extensions>
<scripting>
<webServices>
[code]....
PSS: I have tried to use the assembly fully qualified name as specified in the docs for the SimpleTypeResolver (SimpleTypeResolver MSDN) but this throws a "Operation is not valid due to the current state of the object." exception - which is an error caused when the TypeResolver cannot resolve the name?
My problem was never passing in a List(of Object) into my webservice (I simply posed the question as such to simplify it for stackoverflow). In such a case I would be willing to completely accept using a Generic List(of) but my problem was actually that one of my custom objects implemented a property with a strong typed List(of) so for example:
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS EmailAddressList}
which now needs to be changed to
Customer {CustomerID AS Guid, FirstName AS String, LastName AS String, EmailAddresses AS List(Of EmailAddress)}
This is admittedly not the end of the world and is probably better in the webservice context (as you have suggested) but definitely a detriment when it comes to internal application usage of my Collection properties. What this means is that once I have this property I either need to cast it to my CustomCollectionList every time I want to use some advanced feature or I need to implement another property which exposes the CustomCollectionList.
I have the following web-service which works perfectly as long as it is accessed from a clientside script (javascript, jquery)
<%@ WebService Language="VB" Class="WebService" %>
Imports System.Web.Script.Services
Imports System.Web.Services

2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.

I am wanting to get the users IP address (the logged in user will be running the application under there user context on there local PC), but many PC's in our environment have multiple NIC's that have been added by VMWare Workstation, I would like to exclude these type of bridged connections and only show the "primary" NIC on the PC.The following function will get the IPv4 address, however on my test PC it is returning the bridged connection and not the IP Address of the network facing NIC.
Shared Function GetIP(ByVal computerName As String) As String
'Dim ipEntry As IPHostEntry = Dns.GetHostEntry(computerName)
'Dim tmpAddr As IPAddress() = ipEntry.AddressList

My users have a mixture of DHCP and static addresses so cannot limit the NIC to either of these connection types. We tend to have a 172.16.x.x IP range, so is there a way to modify the above function so that it will only return a 172.16.x.x address?
