1. Win32lib
Hello,
I'm usually just lurking but here's my contribution for what it's worth.
-- Software ID: win32lib
-- Version: 0.55.1 19/Dec/2000
Line 1620 contains an error which results in SIZEOF_MSG being two bytes
too few. Consequently acquire_mem(0, SIZEOF_MSG) grabs less memory than
required and calls to GetMessage write past the end of the allocated
memory with unpredictable results. If this has been fixed in a later
version of the library then "good on yer" ;)
-- Type MSG
msgHWnd = allot( Long ),
msgMessage = allot( Integer ), *** Should be allot( UInt )***
msgWParam = allot( Long ),
msgLParam = allot( Long ),
msgTime = allot( DWord ),
msgPtX = allot( Long ),
msgPtY = allot( Long ),
SIZEOF_MSG = allotted_size(),
HTH.

Thanks for this bug fix. You too Matt. There is a similar set of minor bugs
in many other structures too, in that they use Long instead of UInt and thus
return a signed 31-bit value instead of an unsigned 32-bit value.
I've fixed the fetch() and store() routines to treat UInt and Long correctly
too.

Is there a way to disable the maximize/restore button on the system menu? I
want to force my window to me maximized or minimized but it wont stay that
way unless i enable just the minimize button but then the close button is
gone and i dont see any way to enable it( i looked in win32lib and the win32
help)

include win32lib.ew

atom style
-- get the present style
style = c_func(xGetWindowLong, {getHandle( SimpleWin ), GWL_STYLE} )
-- disable MAXIMIZE button
style = and_bits(style,not_bits(WS_MAXIMIZEBOX))
-- disable MINIMIZE button
style = and_bits(style,not_bits(WS_MINIMIZEBOX))
-- This disables sizing and stops the user from sizing the window
style = and_bits(style,not_bits(WS_THICKFRAME))
-- set the new style
style = c_func(xSetWindowLong,{getHandle( SimpleWin ), GWL_STYLE, style})
WinMain( SimpleWin, Normal )
