Following my previous thread about SubClassing, I have another question:

Since Subclassing using SetWindowLong API is limited to windows in your own thread, I tried to think about ways to Subclass other windows:

When I SetWindowLong with the new address of the proccess, I assume what it does is change the value of the address in the memory.
Is it possible to Subclass othwer windows using CopyMemory in any way?

I'd appreciate any reply.

Thanks.
