Consuming Web Service From Console App?
Dec 13, 2010
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 a webservice being consumed in the WinForm application. I generated a web service wrapper and invoked a web service method asynchronously. I get following exception in my result completed event handler (the event is raised from within the web service wrapper class).
System.Reflection.TargetInvocationException: An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
---> System.Net.WebException: Unable to connect to the remote server

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.

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:
Code:
Dim intOffset As Integer = TimeZone.CurrentTimeZone.GetUtcOffset(DateTime.Now).Hours
'Substract 1 if we're in daylight savings mode

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.
System.Web.Services.Protocols.SoapHeaderException: com/mysql/jdbc/Connection
at System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(
SoapClientMessage message, WebResponse response, Stream responseStream,
Boolean asyncCall)
[code]....
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 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?

I'm currently working on a VB. Net web service calling another web service running in the mainframe. I was provided with the WSDL file and I generated a proxy class using wsdl.exe. Upon attempting to invoke the method of the mainframe web service using the proxy class, I encountered an exception saying "Conversion from SOAP failed" coming from a line of code in the generated proxy class.

I am creating a simple XML web service and have run into something I can't quite explain.My web service class has the following structure :
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
[code]....
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'm working on a project that simply changes the wallpaper periodically...it works fine...I created two seperate projects...1) a forms application 2) console application........The forms application gets the data and settings from the user....the console application reads the data and settings from text files created in the forms application and does the job of changing the wall paper...i've got mine set to change every minute...I realy want to get this finished, but am stumped by a few things....
1) how can i get my console application to run as a windows service..have tried the SC Create command..no good.
2)how can i get it so the console program runs as an icon on the system tray near the clock.
3)When i want to publish to create the setup.exe...should i somehow merge the two projects together or publish each one seperatly and use some sort of batch installer.

I have a .Net Console application which displays thousands of lines on the console each minute. I want to convert it to a Windows Service, however I still need a way of viewing these messages. There are far too many messages to write them to the event log or even a standard log file. I was wondering if there were a way to write a systray app that could simply intercept these messages from the service and display them in a console window. I have no need to save older messages, I only need to see current activity.

I have a console app that is supposed to async call a web service...i don't get any errors but the completed handler doesn't seem to complete correctly. I have a subroutine with a loop that is supposed to fire off say 6 seperate calls to another routine that calls the service. The completed event handler routine puts data into the database..If i put a thread.sleep under the call to the routine calling the web service. The completed event handler fires but only one record is put in the database instead of the hundreds expected and only that one webservice call appears to fire.I should mention that this works as expected when calling the sync method of the web service within a console app and the asyc calls work as expected from a windows forms app. I just need it to work async within a console app..

I have a console application that is ready to be used as a windows service, I have been looking around for a couple of hours and tried many of the tutorials out there but none of them worked with me.
The closest one was: [URL] but it didn't go into the process of doing it. I converted that code to VB.NET but then I don't know where to go from there. I have the Module1.vb which runs my console application all ready to be used.
show me a way to use my console application as a service, I tried using the InstallUtil feature but my app never showed under "services".

i 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.

How do I consume my WordPress blog's RSS feed to display my latest blog posts on my homepage? I ran into the following piece of code to do this:
Function GetRSSFeed(strURL as String) as DataTable
'Get the XML data
Dim reader as XmlTextReader = New XmlTextReader(strURL)
[Code]....
But it errors out at this line: 'ds.ReadXml(reader)' with the following error:
A column named 'comments' already belongs to this DataTable.
Perhaps it doesn't work since this code is from 2003? Does anyone have a working code sample?

I was thinking of adding a simple bandwidth monitor to a console application and I was wondering if it would be possible to keep a line in the console window visible at all times. I could set something up manually to pass new console output into a method that would get the contents of the console, clear the console, add the bandwidth data on the first row, then rewrite each line of previous information back to the console, etc.. but that seems like a really hacky way to go about it, and I'd be limited to the amount of rows visible at once in the console window (no scrolling).

I have two ASMX web services consumed from javascript. The first service performs a long operation and updates a database table on its progress. The second service polls that same database table in order to report the progress to the end user via a progress bar.
My problem is that the long process seems to be blocking the polling service. When I log the activity of the javascript, it seems to be requesting the long service correctly, and then starts to request the polling service once a second asynchronously (note: the long process is asynch as well). Both request types either use setInterval or setTimeout which shouldn't halt the browser. Yet when I look at the activity of the javascript, none of the responses from the polling requests return until the long process completes. So it seems the long process is blocking the polling requests until it's done.

We have a VB6 application that consumes Java webservices with soap.That works fine on XP and Win7. The login to the webservice times out.Under xp the client try to reconnect 2 times (is one call to the webservices) and then ask for new login data from user. With win7 that dont be OK.If the login is timed out, the client try to reconnect 9 times with one call. The code is the same. I trace this with wireshark.

I have a windows form application and also a exe application that both uses the same dll whic I place in the bin directory The dll is using crystal report and thus I need to reference com objects and other .net drivers. My question is following: Where should I put these references, in the class library (dll) or in the windows form / exe applications. If I put them in the dll, will they automatically be loaded when call the dll (entry point) or do I need to something else (create in installer etc)

I attempt to serialize an object, and it throws an exception as shown below. I assume it attempts to serialize also the UserControl that subsribes to an event of the class I try to serialize. This is not desired. So how do I avoid serializing events?
