I would like to use Key_Down or a similar method to allow a user to popup a msn popup displaying an rss fee, this is what i have so far:

if(KEY_DOWN(VK_F12)
    {
        DisplayToast("Key Press", "Test";
        strcpy(sResult, "");
        return TRUE;
    }

    return FALSE;
}

any ideas on how i can fix this?

i think i have got some success using getkeystate

are you missing a closing parenthesis?

btw, don't use key_down for that (or getkeystate and checking for a key that is down, which is infact just what key_down does)! use key_up, or even better key_pressed...  by using key_down you will open constantly new toasts as long as the user is holding down the button....
