No, the transparency only affects painting, not event propagation.  In 
that respect it will behave exactly the same way as if it were fully opaque.

However you might try giving the transparent window the FLOAT_ON_PARENT 
style and then Raise() the parent window and see if it will then get the 
keyboard focus like you want.  Mouse events will still be a problem however.
