Simple question on PostThreadMessage

[cyberninja]

I have 2 questions:
1. Does PostThreadMessage() work crossing process boundary?
2. How to get a Window Handler (HWND) from a function who may not know the information about the caller process or window?

Thanks

Yes PostThreadMessage works across processes.
However it seems that WM_COPYDATA does nto work in this case.

It states explicitly:do not call the PostMessage functionI think it can be assumed that in this context the PostThreadMessage function is the same as the PostMessage function. It's in the documentaion.
