Answer 1

First of all SetWindowLong is superseded by SetWindowLongPtr, you should use that function.

Are you trying to change the WNDPROC of your own console window or another process?

From the MSDN docs :

GWL_WNDPROC -4 Sets a new address for the window procedure. You cannot change this attribute if the window does not belong to the same process as the calling thread.
