Before you start your request (before the get) you need to assign the receive stream:
HTTPCli.RcvdStream:=TMemoryStream.Create;
Then, in the OnRequestDone, as has been explained, you have the rcvdstream to read from:
var StringList: TStrings; .... StringList:=TStringList.Create; THTTPCli(Sender).RcvdStream.Seek(0,soBeginning); StringList.LoadFromStream(THTTPCli(Sender).RcvdStream); //Use StringList... Stringlist.Free;
IMHO a slightly better solution:
HTTPCli.RcvdStream:=TStringStream.Create('');
..// OnRequestDone event StringList:=TStringList.Create; StringList.Text:=TStringStream(THTTPCli(Sender).RcvdStream).DataString; //Use StringList... Stringlist.Free;
You are getting the access violation because you didnt allocate the stream before starting the request.

I don't really know what to do with TMemoryStream... i need TStringList ...
the site isn't that big, so it should be any problem... But i still don't
know how do i convert the recived stream to TStringList... ;-(

Convert the received stream to a string list ? Arno told you: AStream.Seek(0, sofromBeginning); StringList.LoadFromStream(AStream);
But if you want to convert to a string list for analysis, it is probably
not the most efficient way
to do that. You should probably use a TMemoryStream and direction use the
data in memory :
var
P : PChar; // Will point to HTML data (or whatever data you received)
N : Integer; // Will contains the number of bytes
begin
P := PChar((THttpCli(Sender).RcvdStream as TMemoryStream).Memory);
N := THttpCli(Sender).RcvdStream.Size;
// Now you can use P and N to analyse the document received. Very
fast.
// Don't forget to free the stream when processing is done or you'll have
a memory leak.
