You don't. However, win32lib already calls BeginPaint.
You just need to call getDC() and it will work:
-- onPaint_MainWin
procedure onPaint_MainWin( integer self, integer event, sequence parms )
-- hdc = w32Func( xBeginPaint, { getHandle(MainWin), ps } )
hdc = getDC( self )
if not w32Func( xBitBlt, {hdc, 0, 0, vxScreen, vyScreen, memdc, 0, 0,
SRCCOPY} ) then end if
-- w32Proc( xEndPaint, { getHandle(MainWin), ps } )
end procedure

Thats strange but seems to work....
( Im not asking why that was implemented this way)
Now on to figuring out the scrolling of my virtual window,
hopefully it will Paint properly....I'll post it so you all can add
it to the Win32lib demo's.
