C# - Dynamically Call Web Service?
Dec 28, 2009
I need to dynamically call web service! For this I made simple web service Service1.asmx
Then I created the proxy class for the Service1 Web Service, I use the WSDL.exe utility and following command at the command prompt: wsdl /language:VB /out:myclass.vb http://localhost:3245/Service1.asmx?WSDL
This command create class myclass.vb. That class I include in my Windows Application project, but when I do this I get lot of errors.
This is the how created class look like:
Imports System
Imports System.ComponentModel
Imports System.Diagnostics
Imports System.Web.Services
[Code]....

I inherited a working WCF Web Service with one major flaw - the WCF Service consumes memory and does not release unless the service is restarted. After a half a day of requests hitting the web service, the memory on the server hosting the service climbs to close to 2 gig and is dead in the water.
I'd like to be able to release memory after the web service has received its response but cannot figure out how (WCF is still new to me). [code]...

I have a very simple web service that adds two integers
<WebMethod()> _
Public Function AddNumbers(ByVal a As Integer, ByVal b As Integer) As Integer
Return a + b
End Function
Is there a way to dynamically invoke this service without having to add a web reference from VS? Is it possible to maybe pass the parameters through the URL [URL]

I'm having one basic aspx script that needs to load some "plugins". Every plugin has its own settings and it should perform different logics. What i'd do in php is create a class for each plugin, load that class, pass the settings file to it and call some method on that class that would give me some output. But is it even possible in vb.net? I'd need to have multiple files with multiple classes, load those files, depending on the plugin name and call some method on them to parse that plugin's settings.

I've created a dialog which I'd like to popup from any function or sub in any class or form that I have in a project. It would nice to have it work exactly like a messagebox except it's got a progressbar and a cancel button on it. It's job is to display the progress of other functions so it should just stay open until I close it or the user selects cancel.Now I've found many of the basic examples on the net and have got the dialog working exactly as they have shown it. The trouble is that the examples are using a counter or thread.sleep which simply adds +1 in the DoWork sub. In other words, it validates that a worker thread can update a progressbar but it's a closed loop that only exists in the dialog's class.The examples don't show how to call an unkown function in another class dynamically, they're simply a hard coded 1+1 in DoWork. To me it's not a real world example because it doesn't show how to plug into the dialog or get a communication stream from other classes and functions that are running and wanting to increment the progressbar.[code]

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'm working in VB.Net and I'm trying to make a piece of code more generic.In fact, there's a big Select Case statement that build a ProxyServer based on a value passed in parameter (a string).
Select Case _strNteraHL7
Case Constantes.NomPRPMIN306010
strUrl = ObtenirUrl("ProviderDetailsQuery", _strVersion, _strEnvir, True, _blnSimulCAIS, _blnSimulPDS, _blnSimulPDSSIIR, _blnSimulPDSInteg)
[code]....
or something similar, so I can remove all those big switch cases, that repeat the same thing 30 times.objWsHL7 being an object or type "object" at compiling.Again, in another switch case statement,
objMsgHL7Out = _objWsHL7.ProviderDetailsQuery(_objMsgIn)
objMsgHL7Out is a System.ServiceModel.Channels.Message
_objMsgIn is a System.ServiceModel.Channels.Message
_objWsHL7 is an Object

I have a asp.net web application with jquery controls. I have a datagrid that will display data from a database table and created a WCF Service to access the db and return the data. I want to be able to call the WCF service from this application which is on a different server and have the xml data returned, converted to json format to be used in the datagrid which is a jquery widget. I have tested the web service and it works fine. Should I call the web service from the javascript function within the xml or create a .net method behind that calls the service and then does the conversion? From these how would I get started?

Is there a way to identify the source of a WCF call ?I'm trying to find a realiable .Net property that will let the service know the address (URI) of the calling Web Service.Especially in the case where two Web Services are hosted on the same machine.

I have kind of a big quesstion...ok here goes...Usually if i understand it well...web services work in a way that i write a method to get some data from the database and then some other user/client adds a reference and calls my service and gets the data...now in my case i have to get the data and actually post it to the user/client in xml(in soap maybe) i guess....so here is what i do...
[Serializable]
public class MyClass
{ [SoapAttribute]
[code]....
So basically....I serialize it to xml(and soap) and convert it to string and then upload this string to the web service url...I just want to know if what i am doing is right?...i want to basically get the data convert it to soap xml and then send it over to the user's web service url...

I'm using ASMX web services in VB.Net in VS 2005. I am calling a function method on the web service that returns a true or false value. This works fine if I call the the web method synchronously, but if I want to call the method asynchronously, the function returns to a sub and there is no return value; therefore, I can't tell whether the result of call is true or false. Is there a way to make an asynchronous call and still get the true or false result (perhaps using the userState Object)?
For Example:
Dim MyResult as Boolean = MyService.GetResult(10)
Dim MyResult as Boolean = MyServer.GetResultAsync(10)
This doesn't work the compiler complains: "Expression Does Not Produce a Value"

I used the same lines of codes to call a SQL server store procedure to export sql data to an XML file:
1. If I call the stored procedure from a window form application, it works and generates the file at the designated location.
2. If I call the stored procedure from a window service application with a setup project, and the install process run well, and I started the service, and checked the event log, it showed the service start successfully, BUT it FAILED to generate the file at the destination folder. I also run everything as administrator, but it still failed to generate the file. It made me wonder if a window service can call a stored procedure. Because, again, mine ran fine with the window form appl, but window service, I would like to have your sample codes. I have googled around for 3 days now, but could not find the answer. I use vs 2008, sql server 2008, and Windows 7

I'm building a web service client using vb .net. The web service is secured with ssl, basic authentication and also requires client certificates. So I created a web reference in Visual Studio and provided the credentials:
Dim cred As New System.Net.NetworkCredential("usr", "passwd")
Dim proxy As New SimpleFromLocal.simple
proxy.Credentials = cred
Console.WriteLine(proxy.helloWorld())
This works as expected, as long as I turn off mutual authentication on the server side.I added a client certificate like this:
Dim cert As X509Certificate = X509Certificate.CreateFromCertFile(certFile)proxy.ClientCertificates.Add(cert)
The certificate is loaded, but the web service call fails. I could post the exception, but it is in german, which is an issue on its own. It basically says: Authentication failed, because the remote site closed the connection.I tried debugging the ssl handshake on the server side and it looks like the client certificate is not transmitted.So what am I missing here? Is it required to install the client certificate on the local machine?Edit: The error thrown:

I have a WCF self-hosted as a Windows Service.When I start the service (under the NETWORK_SERVICE account), I can consume the service from my ASP.NET application on a different server.However, the business rules have changed. Now I need to run the service under my own account. I am able to stop the service, and start it again under my account. No problem there.Until I try to consume the service from my ASP.NET application on the other service. I get:
A call to SSPI failed, see inner exception
