I use fw 1.1, and I'm considering an upgrade.  I'd like to replace some win32 
api code with .net equivalents where possible.  Does anyone know what 
versions of .net, if any, support the following 6 functions?

1.  play .wav file via PlaySound.  (I think fw 2.0 supports this.)

2.  screen/rectangle capture to bitmap via BitBlt, GetDesktopWindow, GetDC, 
ReleaseDC.

3.  program initiated richtextbox vertical scrolling via SendMessage, 
EM_LINESCROLL.

4.  flicker-free complex updates to a richtextbox via SendMessage, 
WM_SETREDRAW.

5.  custom richtextbox inter-line spacing via SendMessage, EM_SETPARAFORMAT, 
PARAFORMAT2.

6.  flash attention getter via FlashWindowEx, FLASHWINFO.
