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? I tried loading up the .asmx page in IE on that server where the file is being hosted and it just asked me to save the file-would never open it to view as a page. That is the error i get when i try to load the .asmx file from my server.
View 1 RepliesI'm writing an asmx web service in visual basic, and I would like to put in my web service an enum that should be available to the web service's callers through the wsdl. But how could that be done? I'm writing my enum in the web service class, but it's not being published in the wsdl. I've already done this kind of thing successfully using C#, but I cannot understand how this is done in VB.

We're in a strange situation with a legacy winforms VB.NET 1.1 application using ASMX web services. Trying to send a user Token from a WindowsIdentity object as a parameter to a WebMethod. I will be adding a 'HACK: comment. System.Security.Principal.WindowsIdentity.GetCurrent().Token
The token is of type IntPtr, the first problem is the WSDL being generated doesn't support IntPtr with the error of 'unsupported type'I'm aware this is a big WTF question and sounds insecure, so any simple helpful alternatives are welcome but there are a lot of constraints on how we can change this system, including complications with the hosting environment. So I would just like to get our piece of data over to the web service to save a lot of other headaches.

I have created and deployed a windows service application and I added this line of code "System.Diagnostics.Debugger.Launch()" in the beginning of OnStart method in order to be able to debug the service but when I start the service the nothing is happened. I think the OnStart method have never fired otherwise the visual studio will popup once the debugger.launch line is executed even I tried to write some text to the event viewer to make sure but nothing gets written to the events viewer after I started the service. I included also the debugging symbol in my windows service setup project but I end up with the same result.Why it's not working? How can I make sure that the OnStart method gets fired or not?
View 2 Repliesi am building a WCF Service Library that has to check our CRM database. Unfortunately when i try to debug the service with the WCF Test Client i receive a "Failed to invoke the service" error. I have stripped down the service slowly adding things back in to help figure out what is causing the error. I found out that it is cause when i call a new instance of my CRM service object. Is there something that i need to do in order to fix this error and be able to step through the service to debug it??

View 1 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

View 1 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.
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.

We 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

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.

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.
It looks like they are converted to regular date types in the generated proxy object.I'd like to optionally pass null values for these dates.Other than switching to WCF (no time to learn it right now), what is the best way to handle this situation. It looks like I also cannot pass NULLABLE date types.
