AThread.Data... 2 different objects stored..

Hi

I'm using 2 different TObjects tocrepresent my client connections.

I have a TUser, and a TFileClient. Obviously these are stored in the thread
data.

A File transfer session will have its own connection - The problem is the
OnDisconect method. I need to free the object but I am not sure how to
determine what object it is - TUser or TFileClient.

Is there a method I am missing for doing this?

I tried: If AThread.Data = TUser... Incompatible types..

Any ideas?
