on the active x

[moussathiandoum]

I want to passs parameters to an active x( for example a char []) and the active x will return
something ( for example a char[])
how to do this if it is posible)

Yes, it is possible. ActiveX components often use public Properties for the exchange of data, but there are other ways. It's a big subject area and there are many different types of ActiveX components, so without any details, I can only refer you to the comprehensive MSDN documentation on it.
