I have a WCF Service (with installer) that I have built and installed in Windows Services. Opened up Admin Tools, Services, and started the service without a problem. So now I'm beginning a new project (a simple Windows forms app). I want to consume my new WCF, but have no idea how. I can't seem to add a reference / add a service reference to 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
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
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.
I have a VB.NET WCF service hosted as a Window Service. I was able to create an install package, install the service to my machine, and start the service manually from Services in Administrative Tools.Now when I try to reference the service in my test console application (Address: http://localhost:8080/), I get the following error:There was an error downloading 'http://localhost:8080'.` Unable to connect to the remote server No connection could be made because the target machine actively refused it 127.0.0.1:8080`

We have a web app that contains web methods. I want to invoke one of those methods from a console app. I am new at this but I wrote a console app, added a service reference and tried to code invoking it. If my web method is called "Transmit", I expected to see Transmit in the namespace I specified but instead I see "TransmitRequest", "TranmsitRequestBody", "TransmitResponse" and "TransmitResponseBody".What are these things?Have I done something wrong?How do I invoke the web method in the web app from the console app?

I have an interesting issue that a client reported It turns out that the desktop application they are using is changing the times returned by the web service to their local time so it looks like the data is off. We're in UTC-5 while they're in UTC-8 so 8:00 AM is returned to the GUI as 5:00 AM which is causing confusion. I've done this riddiculousness to get around it for now:

I have myself a self-hosted WCF server setup, which serves a clientaccesspolicy.xml and an index.htm which is just points to my xap (accessible via app.xap).
I'm currently serving them via the following code:
Public Function GetPolicy() As System.IO.Stream Implements IClientAccessPolicy.GetPolicy
WebOperationContext.Current.OutgoingResponse.ContentType = "application/xml"
Return New IO.MemoryStream(IO.File.ReadAllBytes("Server Files/ClientAccessPolicy.xml"))
End Function
Public Function GetIndex() As IO.Stream Implements ISilverlightServer.GetIndex
[Code] .....
It works, does the job I'm after. However, I don't think this streams the xap properly, and I know it's a streaming type. If this isn't streaming it properly, how should I stream it? (The endpoint that the XAP and index.htm files are coming through has a webHttpBinding binding). Is it being streamed properly? Or should I make some changes?

Wrote a 'webservice' with Netbeans wizard, runs on glassfish. I added a reference using the wsdl to my .NET client, VB if it makes any difference.The issue is a SoapHeaderException.

I've tried writing the string in a soap envelope, but still receive the same message. So passing a string is kaputt, as it should be; why would the WS know to parse a string, and simply instantiating and calling the method from the object as if it were local isn't working the way I think it does.
I am implementing a VB.NET desktop application which consumes a web service.
The web service implemented in Java and I currently using Tomcat on my localhost to host the web service.
The web service requires secure communication with the client and so I have followed instructions that outlined how to use Java's keytool.exe to create two .jks keystores (one for the client and one for the server) and then create two .cer certificates (one for the client and one for the server)
I have placed the keystores and certificates generate into the directory where the web service is expecting them (according to the instructions)
I have installed the certificates into TrustedPeople and have attempted to use the certificate by setting the ClientCredentials.ClientCertificates property like this:
myServiceProxy.ClientCredentials.ClientCertificate.SetCertificate(storeLocation.CurrentUser, StoreName.TrustedPeople, X509FindType.FindByIssuerName, "name")
I keep getting the following error message when I try to call any method:
An error was discovered processing the <wsse:Security> header
My problem is that I don't know how to use this in the VB.NET client application that is consuming the web service. I could be doing this completely wrong.
I am trying to populate a combo list box with the results of a web service. The web service returns a dataset with two columns.

I am creating an XML web service that passes an array of custom types. In my consuming code I am referencing the code as a web reference which I have given the namespace MYWS. Now in code I am trying to assign the results of my web service call to an array of my type like so..[code]When I do this the complier complains, saying: "Value of 1 dimensional array of my.namespace.MyClass cannot be converted to 1 dimensional array of my. namespace. MYWS.MyClass because my.namespace.MYSW.MyClass is not derived from my.namespace.MyClass"Now I understand the message, the thing is they are the same class. The class is declared in my calling code by the web service references a dll from that project. How do I tell the compiler that these are the same type?

Invoking my method using the built in VS web service test harness works fine. I created another project, in another solution, to test consuming the web service. I added a web reference to my project and set it so I could reference my web service by using "localWS". Then in the page load event of my consuming class I tried to instantiate an object of my web service:
Dim srv As New localWS.MyWS
But there was no "MyWS" type found. There is however a localWS.MyWSSoapClient class. When I use it I can invoke my web methods. My question is, why can't I create a straight up version of MyWS class? In the tutorials I'v read, and in the book I have, example consuming classes for .NET XML web services can instantiate objects of the web service class they are consuming. As a further test I added a new web form to my web service project and from there I was able to instantiate a MyWS class.
I am struggling to send parameters to a VB.NET WS(web service) that is hosted on Windows Azure. Getting a simple hello world (no parameters) works fine, but for some reason my parameters on the web service side are null? Web service function to be called (IService1.vb):

I did this by executing an OleDbCommand with a query and a connection string.How do I accomplish the same thing with the new "Windows Search Service" (Windows Server 2008) by using VB.NET? Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?
View 1 RepliesWhen you create a Windows Service, you create a list of the services you want to start. The default is this:
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service}
Can you have multiple instances of the same Service class (that bind to different addresses or ports), like this?
ServicesToRun = New System.ServiceProcess.ServiceBase() {New Service("Option1"), New Service("Option2")}
Or will that cause problems? Should we use two different classes instead?
We have a server with multiple services written in .Net 1.1 and 3.5 running on a Win 2003 server. Everything runs fine, but when we stop a certain service, an unrelated service stops. I have checked and neither has any dependencies. The service we stop is in 3.5, and the unrelated service that incorrectly stops is in 1.1. We get no error messages, nor event log errors, so we are baffled.Does anyone have an idea as to what may be causing this?

View 6 RepliesI've created a windows service and started a deployment project for it. I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.
I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
