Novice question: Can Web Service call client application?

I'm novice here and I'm sorry for stupid question. We are trying to
understand web services architecture, is it better than TIBCO.Randevouz and
does webservices fit our needs.

I understand, I can make web servce and a client applicaiton. Client will
call the service and will receive some kind of responce.

But can my client applicaiton receive EVENT from web service? Can I
"subscribe" to, let say, "Clock" web service and web service will send time
update to client? Can web service "push" data or I always have to "pull" data?

thank you.

P.S. if somebody could point me to documentation about "why web services
better than..."

Dear Dmitry,

the way we have implemented this is by using a windows service, which is
called by the webserver (over remoting):
a client subscribes to the windows service (over remoting) while a
webservice publishes on that service. The service notifies then alle
subscribed client.

Hi, I have a web service that process a client call. When a client makes a call to the web method the method needs to query some data from a client_A and return the data to the calling client_B. How should I design the way the web service will call client_A to retreive the data needed for client_B? I am using .net 1.1 and c# Thanks

We are working in C#/Winforms and are using asynchronous client-side web service calls (the Begin... and End... methods supplied by the web reference creation). Many of these calls are contained in Windows forms that the user can close before the web service call has completed.

I have a Web Service that I am reponsible for that we use for data integration purposes. Recently I have been tasked with sending some of this data to a third party. Because they need to receive the data in real time. They have requested that I subscribe to a Web Service that they have published. The only problem is that they often take longer than 30 seconds to process my data before I get a response back from them. This is taking far...

Please note this is NOT a rant or complaint! And yes, I'm over-simplifying, but intentionally. Here goes... With ASP.NET Web applications I like that I can access data from anywhere without installing anything on the client (but I hate HTML and markup in general and it's limitations, the request/response model, state management, etc). AFAIK, Smart apps or smart clients or whatever we call them are simply variations of Web applications...

I have written a simple WCF service hosted in a Windows console application and a simple WCF client console application that connects successfully to that service and retrieves data. I then ported the console application to WinForms and also got that to work properly. My next move was to host the WCF service in a Windows service application. I believe I have that working correctly, but I can't for the life of me get a client to connect...

The web service is called by a program running on pocket pc. When to call the web service, the first call is still ok, but for the second or later calls, it will throw "403 Forbidden" WebException. When to test it using the web interface on pocket IE, everything is fine. Before there was no such problem, it only happened within a week or so. I suspect it's caused by the server's firewall settings, but how come the first call is ok? This...

Hi John, Hopefully this post will find its way back to you - or perhaps be answered by someone else. As I mentioned in my last post on the earlier portion of this thread, changing the serialization settings for the build handled the initial slows we encountered when invoking the web service. Since that time, we ported the original VB.net code over to C# - this was done to make it cleaner easier to include the project in the rest of...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
