I am looking for a way to intercept and modify the html stream as it is 
received but not one page its a constant stream that is received.

Some one please let me know if its possible and maybe a small sample to 
explain how to do it, even the correct event i could use would be most 
helpfull.

Thanks.

You cannot intercept the data that TCppWebBrowser receives.  You will have
to download the data yourself separately, then modify it as needed, and then
lastly load it into the TCppWebBrowser for displaying.

Would i be correct in thinking loading the html using clientsocket into a 
memo and loading the memo into tccpwebbrowser ?

You do not need to use a Memo.  Use a TMemoryStream instead.  You can use
TStreamAdapter to pass the TMemoryStream to the TCppWebBrowser's
IPersistStreamInit interface.  Search the newsgroup archives at
http://www.deja.com for examples.

And I would not suggest using TClientSocket.  HTTP is a complex protocol to
implement from scratch.  You should use an actual HTTP component, such as
the one found in Indy, ICS, Synapse, or any number of other third-party
implementation.  Or use the WinInet or WinHTTP API from Microsoft.

Would this allow me to change the html in the stream as it comes in ? this 
is why i was looking to use the memo control so i can see the stream and 
record it so i can modify the stream as required once the memo has saved the 
recorded stream..

Yes.  But you won't be able to load it into the TCppWebBrowser until you
have all of the data available.  You can't do manual real-time streaming
into TCppWebBrowser.  If you need that, then you will have to implement a
proxy server instead.

You can do the same thing with TMemoryStream, or any other kind of stream
that you want to use.
