Connection to IIS Service

Hi All

How to develop a application in eVc 4.0 which connects to a webservice and
get the data returned by it.

There is a webservice name it 'getInfo' with parameter 'id' which returns
the information on the parameter.

how to access this service from a eVc pgm.

From my earlier posts i have understood that we can use

CHttpConnection to connect to the service and the returned data can be
parsed using MSXML.

But i don't know how to use these classes. I believe after connecting to the
server, we have to post the data (for calling the webservice).

Please help me in giving a idea how to do it. Some code snippets will be of
help.

Regards
Kiron

I am getting a error that "The server name or address could not be
resolved". How to rectify this error. Please Help
