Keyboardbuffer clear

[Marc Vanzegbroeck]

Hi,

Probably this is aswer bevore, but I can't find it in the forum.
I have an application with a barcodescanner. It is a barcodescanner connected via USB that is simulating the keyboard

If the barcode is not found, It play an errorsound, and show a message.
The problem is that sometimes the code read by the barcodescanner is so long, that it enter the OK-button of the message, so it is not shown...
I want to clear the keyboard-buffer before showing the alert-box.

Thanks

#pragma BEGINDUMP

#include "windows.h"
#include "hbapi.h"

HB_FUNC( CLEARKEYBOARDBUFFER )
{
MSG stMsg = { 0 };

HWND hWnd = ( HWND ) hb_parnl( 1 );

while( PeekMessage( &stMsg, hWnd, WM_KEYFIRST, WM_KEYLAST, PM_REMOVE ) );

hb_ret();
}

#pragma ENDDUMP

Have you tried calling SysRefresh() ?

[Marc Vanzegbroeck]

Sorry for the very late response

The function CLEARKEYBOARDBUFFER() is working very nice

SysRefresh() is not working

Thank you
