I actually have a menstrip with sub-menu ... File > Service >>> Products
My aim is to add a uri to products so that when on click on product the particular web service will be invoked.
My question is only How Can I add a URI with Products on click ?
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 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

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..
View 1 RepliesI'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

strUrl = ObtenirUrl("ProviderDetailsQuery", _strVersion, _strEnvir, True, _blnSimulCAIS, _blnSimulPDS, _blnSimulPDSSIIR, _blnSimulPDSInteg)

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?

View 1 RepliesI 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:

View 8 RepliesI have a Deployment project which creates an MSI setup file to install a service. (VB .NET) I have a reference to another project which is a win form application and has a setup form which takes the user name, password and some other settings information which will be used by a service. It has "Finish" and "Cancel" buttons. I am creating a new instance of this form on Sub New() of the ProjectInstaller Class, so user can input information, click Finish and installation completes. The service is then automatically started. Now, when I click Cancel on the settings form, I am not able to exit out and halt the installation process. Instead it installs the service !! How can I use the Rollback or Uninstall methods to do the task? I was trying this -
On cancel_click, set boolean var cacelStatus = True
On Sub New() method of ProjectInstaller class, I am checking - If true - uninstall, else - install
How can I achieve this?
I have a vb.net Windows application that calls a vb.net Web Service function. Both the vb.net application and Web Service have been in use for over 5 years and have worked well. The Windows App builds a text file consisting of a number of inserts into an Oracle table, followed by a call to an Oracle package. The Web Service call uploads the text file to the Web Server, loops through the statements in the text files and executes them. It then does a Select statement to put the resultant data in a string which is passed back to the calling program. We have both people on our local area network as well as external users where the call to the Web Server is over the internet.
The data string returned is the pricing for each of the lines inserted in the text file, separated by asterisks. Normal use of this call has anywhere from 1 to a few dozen lines, and the program works fine for this for both internal and external users.
Our problem right now is one external person is attempting to price a job with 491 individual line items. At first it would not price, whether the job was priced from a computer at the customers site or one of our internal people on the LAN. The problem turned out to be the timeout value was not long enough (it was set at 2 minutes, this job takes 5 minutes) so changing both the Timeout value in the Web Service call as well the httpRuntime executionTimeout value in the web.config file on the web server addressed the problem, but only for our internal users on the LAN. Our external customer wants to be able to price jobs of this size going forward, and I am at a loss as to why it errors on internet connected machines but not locally connected machines. Our customer is in New York, We are in Wisconsin, and I am able to recreate the error condition from my home computer.
The other thing is, if I create a VPN connection to our server from my computer at home, this job will price (again, it takes about 5 minutes) but if I disconnect the VPN connection, it gets an error after approximately 3 minutes, http 404: Not Found.The customer can otherwise price all of his other jobs with no problems, it's only this one, very large job that gets the error.
I already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...
View 2 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.

Now here's the odd part, only the one user is affected by this issue. Other users of the application have not reported any errors. When the user logged on to a different machine that worked for another user, they still received the error.

In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website. 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?
