As some of you know, there is a COM reference library called 'YahooMessengerLib'. What I have done with it until now was:
- Login with user and password
- Logout
YM must be started for use to use this library.

YahooMessengerLib has a lot of interfaces but I don't know if we can use them. It would be a great deal to be able to get a little more deep in this SO your help will be appreciated by many coders trying to figure this out in C#.

So... what is your question?

My question is:
How can I program things like: send a message, set my status, avatar, address book, image, etc... ? not just log in and log out.

So... what is your question?

Well what do you have to say now, Messanger API are not used by all users and there is not a lot of experts on this issue, a little google and hard work will get you there, u can't expect us to do your homework right?

C# DOES NOT HAVE TO BE managed code.

C# DOES NOT HAVE TO BE managed code.

Yea and ddanbe is right C# does not have to be managed code, there is a lot of forums about this issue too on google.

Sorry but is that API for Yahoo! Messenger? or MSN?

Baby, I just have to google what i seek: Yahoo! Messenger API and NOT web service API and a million ohter things I can google. So please read better: that does not include YM API. However thanks for your interest and google-ing :). I appreciate it! really

Please read that page. Does not include Y! Messenger. Those are some WEB services API's. Thanks for your replies! :) sorry i posted twice

Yea so why in the head of the page its written:

This site is your source for information about using the .NET Framework with Yahoo! Web Services and APIs. Here you'll find:

Now you dont know how to read also?

Let's not turn this into a flame war :/
OBVIOUSLY google has the resources you're looking for...
