On my serverside pages (intranet environment), I use the following code to find out which user is using the page:Request.ServerVariables("LOGON_USER")How do I use that command in a webservice (asmx file)? I can't use the line above as I get a message saying that Request is not declared.
View 1 RepliesWe are developing a webservice for a client. We are not supose to throw SoapExceptions, so instead, we catch every exception server side, and return a custom Exception class.
Public Class Order
...
End Class
[Code]....
The problem now is, that since my webmethod is returning the type [Object]. The wdsl that is generated does not contain the order, or the exception.
I can change the [Object] to [Order] Or [MyException], but only one of them is generated in the wsdl.
I want both the MyException type and the Order type in my wsdl, but i just cant get it working.
I use jQuery ajax calls to ASP.Net web services (ASMX files) to update the web page data.
I have the database storing code seperate from the domain object class code (in the example code below, there is an Animal class and an AnimalRepository class). I'm implememting a convention that all similar domain object repository classes will have a Store method .
I would like to create a web service that can cater for calling the Store method for any one of these repository classes. To get this to work, in the below code sample, the List(Of Animal) parameter would need to be a generic type.[code]...
I have a very simple ASMX page.[code]...
How do I add Access-Control-Allow-Origin to the response headers so that the webservice can be consumed by multiple websites using AJAX?
I have to send a request to Webservice and I have a working PHP solution, that I have to translate in VB.net

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:

<soap12:Envelope
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I've been asked to write code to track IP addresses of visitors to one of my company's online applications in .NET. This is actually the second one I've done, having done another site late last year. I noticed then, and again now, that I sometimes get the same IP address showing up for what I know is another box.....sometimes a co-worker's and sometimes a box not even in this building. The code is pretty straightforward, here's how I get the address:
Dim IPAddress As String = Request.ServerVariables("HTTP_X_FORWARDED_FOR")
If IPAddress = "" Then IPAddress = Request.ServerVariables("REMOTE_ADDR")
I log the results to a database upon users logging in. My testing this morning on my development box, of course, yielded 127.0.0.1.....fine, just what I expected. When I deployed the code on our staging server, I got my actual IP address (I've seen it enough to know it when I see it). All fine.....but then a co-worker in our QA group went in to do some testing and MY IP address was logged in the database. I know with certainty that we don't share that address.
I also recall seeing this during my first deployment, when transactions from customers in various states around the US were logged with MY IP address. I'm not seeing things... It's almost like the transaction header is being cached and subsequent calls aren't fetching the new user's info.
Branching off from this link it seems that Request.ServerVariables("SCRIPT_NAME") doesn't return anything. I've just set up a simple loop to see if anything comes out at all but with no luck.
For Each s As String In Request.ServerVariables
Label1.Text += s
Next
ServerVariables brings back a list of Strings in key->value form as defined in System.Collections.Specialized.NameValueCollection
EDIT: It seems to be a problem with getting the ServerVariables from a page using master pages. In my code behind model I'm defining the following:
Public Partial Class Test
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Response.Write(Context.Request.ServerVariables("SCRIPT_NAME"))
End Sub
End Class
This doesn't work, quite simply. If I enter the code within the Page_Load event within the .aspx page, however, by doing the following:
<% Response.Write(Context.Request.ServerVariables("SCRIPT_NAME")) %>
i am using vb.net 2008 and asp.net.now i have a form which is used to send email from my page on my website.
the code is as follow:
<%@ Page Language="VB" %>
<%@ Import Namespace="System.Net.Mail" %>
<script language="VB" runat="server">
Sub Page_Load(Source As Object, E As EventArgs)
[code].....
should i replace the "SERVER_NAME" if so what will be its value?Ip address or?what looks like the value of "SERVER_NAME" or what will be its value?
2nd question:
strReferringPage = Request.ServerVariables("HTTP_REFERER")
will i replace "HTTP_REFERER" by something or what will be its value?
How would I return a base64Binary type back from a VB.net web service request? I would like to return the base64Binary of a PDF document from the binary datatype from SQL Server 2008. Is base64Binary the same as Byte? Do I have to convert the Byte to Base64 then to String?

I want to log the "type of" request that access my simple ASMX page. How would I be able to do this?

i want to retrive value as below
string server = Request.ServerVariables("SERVER_NAME");
//Declare the form being accessed ex: Default.aspx
string url = Request.ServerVariables("URL");
// Declare the query string in the URL
string querystring = Request.ServerVariables("QUERY_STRING");
but i got a error Non-invocable member 'System.Web.HttpRequest.ServerVariables' cannot be used like a method.
Is it possible to assign a value to a ServerVariable("Something") using the code? instead of doing it via the IIS?[code]...
View 2 RepliesI have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
How can i turn on debugging when trying to add a service to my VB.net app? How can i change the settings to view it remotely?

View 2 RepliesA little while ago, I managed to get WebServices to return JSON as well as XML from the code-behind of an ASPX.
Today, I needed to migrate an existing ASMX WebService to return JSON instead of XML (which was accomplished with little fuss). My problem became evident in testing the new method.
In the code-behind for the ASMX, I created a new method to return JSON instead of XML. The method works, in that it returns the expected JSON however the new routine breaks every XML-returning method in the code-behind (they all throw "System.NotSupportedException: The type System.Collections.Hashtable is not supported because it implements IDictionary." which is unexpected because the return types are all defined as XmlDocument).
If I simply comment out the JSON-returning method, the XML-returning methods function normally. Uncommenting out the JSON-returning method breaks the XML-returning methods again.
While I cannot find any supporting documentation anywhere, this behavior leads me to believe that in ASP.Net 2.0, JSON-returning methods cannot co-exist in the same module as XML-returning methods.
This led me to try separating the methods in sub-classes like so:
<WebService(Namespace:="http://tempura.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<ScriptService()> _
[Code]....
I have the following test method:Imports System.Web
Imports System.Web.Services
Imports System.Web.Services.Protocols
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<System.Web.Script.Services.ScriptService()> _
[Code]...
Even with the ResponseFormat attribute added the response is still being returned as XML rather than JSON.

We have a set of assemblies which implement web services operations.To build the client proxies, we first build and deploy the web services (assemblies and ASMX files) on the server.Then we use wsdl.exe to point to the ASMX endpoints and generate the classes for the client proxies.I've seen that it is possible to create the proxies from wsdl files (instead of asmx endpoints) using wsdl.exe or disco.exe.Is there a tool to generate wsdl files or event better proxy classes directly from the server assemblies without the need to use a web server?
1) This is a somewhat large project that has been in development for over a couple of years now. The decision to use ASMX web services was made before the existence of WCF.
2) I already thought about writing our own proxy generator and that may be an option if we don't find a tool that does it.
3) We still want to bind to the WSDL contract. What I'm trying to avoid is having a dependency on a web server during the build process.
4) We already auto-generate the proxies in our automated build which runs in TFS Build and that has not been an issue per se. The issue, as I was told, is having to split the build in two parts: server & client. There may be alternatives to avoid the split using some fancy MSBUILD task, but my knowledge on that matter is limited.
5) I do expect the build to brake on TFS Build if the client side code and server side code don't match during compilation. That should have been addressed on the developer's machine before check-in.
6) We have strict control over the server and the client parts. This set of web services serve as a back-end to a Click Once Windows Forms application. Everything runs on an intranet. Every time the contract changes, it is done in tandem with a new version of the client application.
7) WCF is not an option in the short term for this set of web services. When I joined the project over a year ago I was given the task of creating a new set of web services for interoperability with other internal systems. Those web services were designed upfront to be easily upgradable to WCF once upper management allowed us to use WCF. I'll have to take a look into svcutil.exe, but if it does what we need, I'll have another point in trying to convince upper management to adopt WCF.
