I'm trying to invoke an Oracle BPEL web service from asp.net (vb) and having trouble getting it to work. This is the portion of my code in the Page_Prerender event:

The web service doesn't launch though.
I'm not a web service expert, so seeing if anyone else may know how to get this going. I don't need to track the web service - just need to launch it.
as part of a log feature that my client asked for, I'm tring to monitor whenever the browser is closed by the user.
I have created a new web service, registered it the ScriptManager (like in this exmple [URL]
The web method is this:

I have a hardtime to consume this web service as Web Reference or Service Reference: [URL] I'm using VS2010 and when I consume it as Web Reference, I can't use its method because in the reference.cs, it has these errrors:
// CODEGEN: The operation binding 'getStationCharacteristicSummary' from namespace '[URL]was ignored. The encoding '' is not supported.
If i consume it as WCF, then each time I call the service, it complained the encoding error. May someone try to consume it and help me with this.
I'm currently working on a web site which involves a data upload process. The file is currently uploaded to the server method is called (in app_code) where ultimately a DTS package is called (via a web method) to load the data into a database and perform some validation on it.The client has specified that they don't want to have to wait for the DTS package to execute (execution time is less than 5 minutes) so it appears that I need to call the method asynchronously. The user will probably logout or close the browser window while this task is running so I believe I'm unable to run this on an asp.net thread.

On my local machine with the default ASP web server I am able to browse my web service's methods, which have with prompts and an invoke button.But when I deploy this same code to an IIS server and I browse the asmx page I just get a descritpion of the methods.
The web server is running windows 7 and IIS 6.
I am implementing web service into my web application, i added web reference to my application of required web methods from my asmx file.
i am able to create object of this weservice and able to see all the web methods available from the reference object. In debug mode(working environment), i could invoke and get result from the webmethod and working fine as expect. i created test page for testing this.
But, when i deploy same in my beta i am getting below error.(my both test page and asmx file available in my beta server where i deployed)

I've a web services wich can invoke a pc on the internet when a new event has come.
How do I write the code?
I'm working on an existing web application (web site project and some class library projects). In the web site project, the guys created many web services, that are called from the aspx pages (sometimes on client side).
I need to create a new web service, so I was suggested to put it "near" the existing web services. I'm gonna need to make an asynchronous call to my new web services.
So I created the service this way, but when I try calling a method asynchronisly, I have only the method in intellisense, I don't have the method for the asynchronous call, neither the Complete event. Why is that ?
On the other hand, I created a new project, with a web service application and a web site where I added the reference to the web service, and this way I have the asynchronous method and the complete event in intellisense.
In IIS 7.5 i configured my asp.net website for "http,net.pipe" in "Enable protocols".
Note:
net.pipe configuration is done to call another module within the website (SOA). Every thing worked fine with simple asp.net & net.pipe service invocation calling other module. But When i try to call RIA service from silverlight 4 i get the following error
The provided URI scheme 'net.pipe' is invalid; expected 'http'.
Parameter name: context.ListenUriBaseAddress
How can i configure my website to work in http & net.pipe configuration ?
I have been trying to figure this our for far too long and I cannot get my head around it. Every example I have seen seems to be far more complex that I need.
I have a web service in my project (.asmx). I want to call it very simply from a button on a webpage.

In my asp.net application, I am using wcf service to get all the business logic. I am using that service reference in my application to work with that. Now adding that service reference is giving another option Update service reference is giving Generate asynchronous operations. If I check the option and add the service will it generate asynchronous methods for my existing service. If so how do I use the metohd.
View 1 RepliesI have to call a function to run a report through a web service, then call another function to get the data but only after the 1st function has finished processing. How do I make c# wait till the first function has finished processing to run the second function?
my code looks something like:
NetworkCredential Cred = new NetworkCredential("uid", "pw");
ReportWebService reportService = new ReportWebService();
reportService.Credentials = Cred;
string s = reportService.runReportAsync("0ede9884e6394daf73fa418e9bffd4fc");
string report = reportService.getReportData(s);
This code will break because s is not set since the function (runreportasynch) has not finished running to produce s.
We have a custom Ajax checkbox control. In that control we set value (from inside the control) via a web service call (say WSCall1) to the business engine. There is also an event exposed on the OnClick of checkbox for the end user to have their custom code where the end user have their own web service call (say WSCall2). This event that end users will write is handled inside the ajax checkbox control on the "OnSuccess" of the internal web service call (i.e WSCall1) with an expectation that if WSCall1 succeeds, WSCall2 will get executed. This works fine with Firefox and Chrome but not in IE. In IE sometimes WSCall2 gets executed first and then WSCall1 -- actually there is no gurantee which web service gets called first. For WSCall1 we have used " Sys.Net.WebServiceProxy.invoke"
Is there a way we can make sure that WSCall2 gets only executed on the "OnSuccess" of WSCall1? Isn't the OnSuceess supposed to be executed when the WSCall1 thread returns?
I need help calling a web service asynchronously. Current scenario is, I have a classic ASP page which does some processing and then redirects to a ASPX page which would call the wcf service asynchronously and then redirect to another classic ASP page. Im currently using the Asynchronous method to call the service with Async="true" included in the header. Testing the ASPX page induvidually it appears that the service call is asynchronous and does not wait for the the service to process data. But when integrating it with classic ASP page i.e ASP to ASPX to ASP it appears that the process takes a while as if the service call is synchronous.
So is there a better idea to use in calling a wcf service asynchronously. The idea behind my work flow is the ASPX page would be used to call the service and then the ASPX page would redirect back to the classic ASP page is came from. Let me know if there is a work around on how to call async wcf service in aspx page. I dont need the ASPX page to wait for a result or anything it is just used to call the WCF service async
I am using a third party service for location time(zonal).If I pass latitude and longitude of the location with service URL it returns the time of that location in XML format.But the problem is some of the time this service gets too much slow so because of that my home page gets stuck because its a synchronous call of that service.here my code-
string TimeZoneUrl = "http://ws.geonames.org/timezone?";
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(TimeZoneUrl + "lat=" + latitude + "&lng=" + longitude);
XmlElement root = xmlDoc.DocumentElement;
XmlNodeList nodes = root.SelectNodes("//*");
How can I make this a asynchronous call?
Imagine a web service with a method that returns a Customer object, that takes a customer ID as a parameter, i.e.
[WebMethod]
Customer GetCustomer(string customerId)
Now imagine that you're writing an ASP.NET app and you've generated a proxy for the service with the async operations. You create an instance of the service, wire service.GetCustomerCompleted to your handler, OnGetCustomerCompleted, and call service.GetCustomerAsync("12345"). In OnGetCustomerCompleted you apply logic to detect that no customer was found and throw a custom exception, or you want to throw the exception found in e.Error, e.g.:
void OnGetCustomerCompleted(object sender, GetCustomerCompletedEventArgs e)
{
if (e.Error != null)
throw new ApplicationException("GetCustomer failed", e.Error);
if (String.IsNullOrEmpty(e.Result.FirstName) && String.IsNullOrEmpty(e.Result.LastName))
throw new CustomerNotFoundException();
}
(I've omitted the bits of code that sets up a Customer object and persists it through the calls.) You launch the call to GetCustomerAsync in Page_Load and expect to retrieve the result in a handler wired to Page.OnPreRenderComplete. My question is, how do you catch the exception in your page? I know you can catch it with Global.asax's ApplicationError, but what if you don't want to navigate away from your page?
if i have the web application with many pages like add order page, edit order page, and delete order page actually they also interact with the Sql Server 2008 and i also create web service page call Sales_Service.asmx. i know just i need to put something like query into Web Method in Sales_Service.asmx but i have a lot of queries, i don't know which query i should put into it and how the web page call the Sales_Services.asmx
View 2 RepliesA customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
View 2 RepliesI am building a page with databound list control. For each row I want to display piece of info retrieved from web service call. This could be time demanding so I want to render page first and retrieved additional info asynchronously and in parallel later on. Anyone has some tips how to make it? Just to have a more detailed picture it is a product list in e-shop which I want to render so customers can use it (go to product detail/add goods to shopping cart...) but meantime there will be a placeholder displaying info that informations are retrieving which after completion of call will be replaced by result data.
