Web Forms :: ASPX Page Calling Web Service Asynchronous

Jun 17, 2010

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

WCF / ASMX :: Calling A Web Service On A Remote Server From A ASPX Page (website Project VS2005)?

Aug 30, 2010

I am maintaining a web site project in VS2005 and have to call a new web service on a remote server. I've done add web reference, and created the .wsdl and .discomap files in the app_webReference folder. When I try to create a object representing the web service in the code ( wsnamespace.serviceName ws = new wsnamespce.serviceName(); ) the code wouldn't compile.

The web site project is already calling other web services. When I right click on the type representing the web service and "go to definition" it takes me to a proxy class (derived from of course SoapHttpClientProtocol) in the metadata. I think this is what's missing for the new web service i'm trying to call. Have I missed any steps?

I'm using this Ajax script [URL] to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link.

I've searched the web for about 10 hours now, and I still haven't found what I'm looking for.

AJAX :: Stop 2 Asynchronous Web Service Calls?

Nov 22, 2010

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?

Load XMLdocument Asynchronously Or Asynchronous 3rd Party Service Call?

Dec 21, 2010

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?
