Windows 7 Touch Screen Input

[Meerecat]

Hello

I have a Dell Inspiron Duo. It is a nice little netbook but I find the touch screen irritating at times. I can disable it by going to Control Panel>Pen and Touch>Touch and unchecking 'Use your finger as an input device'. I would like to create a hotkey to toggle this checkbox on and off without having to open the dialogue. Can anybody point me in the right direction of where to start?

Many Thanks

Lee

There's a registry setting for that in the HKCU key, look for the "Software\Microsoft\Wisp\Touch" setting and monitor it as you turn it on and off by the GUI and see how the setting changes as you disable/enable it. Then write a regwrite to do the same thing from your script.

Found some C++ code, but dont know about the Atom business and have no Idea if it can be converted to / Accessed by Autoit3

#include <tpcshrd.h>  

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)  {   
    const DWORD_PTR dwHwndTabletProperty =  
        TABLET_DISABLE_PRESSANDHOLD | // disables press and hold (right-click) gesture  
        TABLET_DISABLE_PENTAPFEEDBACK | // disables UI feedback on pen up (waves)  
        TABLET_DISABLE_PENBARRELFEEDBACK | // disables UI feedback on pen button down  
        TABLET_DISABLE_FLICKS; // disables pen flicks (back, forward, drag down, drag up)   
    ATOM atom = GlobalAddAtom(MICROSOFT_TABLETPENSERVICE_PROPERTY);   
    SetProp(hWnd, MICROSOFT_TABLETPENSERVICE_PROPERTY, reinterpret_cast (dwHwndTabletProperty));  
    GlobalDeleteAtom(atom); 
}

Think these are constants

$TABLET_DISABLE_PRESSANDHOLD        = 0x00000001
$TABLET_DISABLE_PENTAPFEEDBACK      = 0x00000008
$TABLET_DISABLE_PENBARRELFEEDBACK   = 0x00000010
$TABLET_DISABLE_TOUCHUIFORCEON      = 0x00000100
$TABLET_DISABLE_TOUCHUIFORCEOFF     = 0x00000200
$TABLET_DISABLE_TOUCHSWITCH         = 0x00008000
$TABLET_DISABLE_FLICKS              = 0x00010000
$TABLET_ENABLE_FLICKSONCONTEXT      = 0x00020000
$TABLET_ENABLE_FLICKLEARNINGMODE    = 0x00040000
$TABLET_DISABLE_SMOOTHSCROLLING     = 0x00080000
$TABLET_DISABLE_FLICKFALLBACKKEYS   = 0x00100000
$TABLET_ENABLE_MULTITOUCHDATA       = 0x01000000

I would try disabling the device in Device Manager, if that works it can then be automated through tools like DevCon

[Meerecat]

It is listed as a USB Input Device in Device Manager. However the regwrite seems the easiest way, at least to my limited knowledge.

Thanks guys

I have found the DWORD that this setting updates in the registry. If I use the registry to change the value it doesn't work until after a reboot, however using the control panel option works immediately. Is there any way around this?

(I realise this is no longer an AutoIT issue, but hoping someone may have an idea).

Many Thanks

Well it is an autoit issue, if you are trying to do it with autoit.

There are a lot of control panel settings you can accomplish via objects and WMI, I'm not familiar with them but I know they are there.

Scriptomatit springs to mind, but unfortunately I'm quite the dunce regarding that also.

[Meerecat]

AutoIT writes the registry key correctly. It just doesn't work until after a reboot. Editing the registry key via the registry directly also doesn't work until after a reboot. However using the option within the control panel (which updates the same registry key), works without a reboot.

Confused lol

My above post still stands.

Sometimes there is more than one way to skin a cat.

Hi John, thanks for your help. I accomplished this by updating the registry key then ending and restarting explorer.exe which seems to update the system.

Thanks again
