Print Page - Flush buffer

Title: Flush buffer
Post by: paja on October 31, 2010, 05:10:42 PM

Hi,

How can I flush keyboard buffer before testing @CODE - FLUSHKEYS does not work. The same problem is with flush buffer for pressing buttons.
If I press button very quicky more times then I get more result - but I need to control it and get only one.

Thanks

If you want to flush GUI related messages, try the following FlushMessages function, and apply the additional condition with g_IgnoreMessages, where you want to apply the flush:

Code Select

$include "windowssdk.inc"
' helper global variable
BOOL g_IgnoreMessages


sub FlushMessages()
	MSG msg
	g_IgnoreMessages = TRUE

	while (PeekMessage(&msg, 0, 0, 0, PM_REMOVE))
		DispatchMessage(&msg)
	wend

	g_IgnoreMessages = FALSE
endsub


sub window_handler(),int
	select @MESSAGE
		case @IDCONTROL
			if (!g_IgnoreMessages)
				' TODO: handle controls
			endif
	endselect
	return 0
endsub
