Could I get a Function Address in a Remote Process

Could I get a Function Address in a Remote Process? And how could I do?

[Dave Kreskowiak]

You don't. The address would be meaningless on any machine other than the one the function is actually running on. So the question because, why would you even need it?

Now I have to use a API to do something. It need a address of function, which in the third process.

Which won't do you any good because an address cannot be called on a remote machine. You can only give an API function an address on the LOCAL machine to call. You cannot give it an address on a remote machine. There's simply no way to represent that. Now, you have to have a proxy running on the machines. On the local machine, the address you give the API function will be a delegate on the local machine in a proxy. This proxy marshals the call to a remote component that calls the real method on the remote. The API function won't know anything about the remote machine.

No! It means both of the two process are run in the local machine which i say

It STILL won't do you any good because each process runs in it's own address space! Think of it this way. Each process thinks it's the only one running under Windows and has access to up to 2 GB's of RAM. The address you get for the function doesn't apply because it sits in a different address space.
