writer api

Hello

I'm new in Zoho.

I want to call web methods in xml-rcp context in vs 2005. Now I use GET method to create user ticket, I know how to get the list of documents (also GET). But if I want to open a document in writer.zoho contex to edit it, I have to sent an xml in post method.

If somebody know how to do it, I'll be grateful for help. Some code samples are desirable:)

thanks in advance
