How to block all Windows Touch Events?

[TobiasSchwirten]

Hi Everyone,
the tool is really nice! Runs smooth so far.
But I have a problem as I want the bridge not to forward any of the hooked wm touch events.
It would ideal if Touch2Tuio collects all the touch events and only forwards tuio so that there are no native WinTouch events anymore (at least in the hooked window).

In TouchHook.cpp is this part:

LRESULT CALLBACK LowLevelMouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
    if (nCode < 0 ) // do not process message 
    {
        return CallNextHookEx(0, nCode, wParam, lParam);
    }

    LPMSLLHOOKSTRUCT msg = (LPMSLLHOOKSTRUCT)lParam;
    if (msg->flags & LLMHF_INJECTED) // block injected events (in most cases generated by touches)
    {
        sprintf_s(s_buf, "Blocked injected (touch) mouse event\n");
        WriteConsole(s_out, s_buf, strlen(s_buf), &s_ccount, 0);
        return 1;
    }

    // forward event
    return CallNextHookEx(0, nCode, wParam, lParam);
}

Setting the second if-routine quick and dirty to "true" makes it a little better, the native win touch does not trigger buttons anymore, but can for example select text or highlight buttons. But still something is happening and you can always see the small cross hairs.

Any Idea how to really get the native touch quiet :-)?

Thanks!

Best regards,
Tobi
