Hello Francois, Thanks for the quick reply.
No, I don't have any message handler of my own in my code. I create an object as the owner of an array of TWSocket objects. I assign the even handler of the TWSocket objects to a member function of that owner object and call ReceiveStr() in the OnDataAvailable handler. Any other reasons that you can think of that could cause this problem? My component verifies if a HTTP proxies supports CONNECT on port 443. I don't think HTTPCli component does what I want to do ... -- Best regards, Jack Wednesday, May 18, 2005, 3:59:06 PM, you wrote: FP> Usually, when you receive the same data twice, it is because you called the FP> message pump from one the ICS component event handler.
