calling windows service from webservice

[=?Utf-8?B?bGVvMg==?=]

Hi All,

I have a question which might be a beginner's question.

I have a webservice whose webmethod has to call a window's service and get
back the results.
What is the best way to implement this scenario.

I am asking this as windows service is an exe and i could not figure out a
way call its methods from webservice.

Please help me with a speedy reply.

Below is the only way you're going to be able to communicate worth a .NET NT
Service application, you need to get more information about it use Google or
get a good book.

That's the only way you're going to be able to communicate with a method in
a .Net Service application.

http://msdn2.microsoft.com/en-us/lib...nd(VS.80).aspx
You want two way communications between your Web service and the NT Service
application, then either you use .Net Remoting or you set a share folder
where the NT service writes Response.txt files out that the Web service will
read. The Response.txt can be a two way communication mechanism between the
two applications, because otherwise, a NT services has no namespace of its
own to allow two way communications

In either case, you need some major changes in both applications. It's
one-way communications with the NT Service via the OnCustomCommans().

Hi Arnold,

Thanks for your prompt reply.
I tried to visit the website link provided by you but it is not
working.Please provide me with the working URL.
I was also thinking about using WCF(latest compared to remoting) but
couldn't find out about how to implement it like where to make an interface
between the two(webservice and windows service), what headers files and major
classes to use to call the windows service methods remotely from web service.
If possible, please provide me with some directions or any sample for this.
Sample based on remoting to achieve this will also be useful for me.

Regards

Since, you're already on a Web server trying to do this, I going to point
you in this direction.

http://www.lhotka.net/Default.aspx

It's got the 3 elements you're looking for to use.

1) CSLA Framework is based on a Web Service as the portal.
2) CSLA framework uses .Net Remoting
3) An application using the CSLA Framework can use .NET Remoting to send
objects between the Web Domain application and a Windows Desktop Domain
application such as a NT Service application.

You get the book and read it to understand what's happening, you download
the CSLA Framework (the source code is yours to use), you download the
source code of the Tracker project for Windows Desktop and WEB based
applications. You put it all together, and you'll see exactly what's going
on, and the lights in your mind will come on as to how you can do things.

You might not never use the CSLA Framework again, but you'll have a solid
foundation.
