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 1 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 ?

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.

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>

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.

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

I am trying to consume the webservice from the .Net environment which was build in Java environment. Currently am trying to forward the ArrayList of type object array as parameter to the WSDL file.Am experiencing the following error message : "There was an error generating the XML document"let me know the whether I need to manually convert the ArrayList to XML . May I know the best procedure to forward the ArrayList to webservice in Java ?
View 1 RepliesWebservices are the address to deliver to, SOAP is the envelope, but how does the data actually get "sent"?For example:I have a class called "GetMeAResult", which calls WebService1.GetMeResult(Param1). Another class declares an instance object of GetMeResult and then serializes it using SoapFormatter.Serialize (memorybuffer,objGetMeAResult).Now how do I send this SOAP envelope to WebService1?
View 3 RepliesII am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"
I realize the problem is the $AE$7 (the $A$3 is correct)
In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

Does link text mean I have to return a concrete implementation? Even though I am using svcutil with the /r that includes my entites(where IMyInterface is defined). I get no errors but it changes all List(of IMyInterface) to list(of Object) and I cannot deserialize it on the client
Error: list(of object) cannot be converted to list(of IMyInterface).
I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.
