06/07/07 - Desativar teclas especiais
Olá,
Neste exemplo que fiz associado a dll que é encontrada no endereço:
http://www.codeproject.com/win32/AntonioWinLock.asp
...é possível fazer o seguinte em FWH:
- Ativa/Desativar alt+tab
- Ativa/Desativar alt+esc
- Ativa/Desativar ctrl+alt+del
- Mostrar/Esconder a barra de tarefas
- Mostrar/Esconder o desktop
- Mostrar/Esconder o Start Button
- Mostrar/Esconder o System Clock
- Rodar um processo em outro desktop
Espero que gostem :-)
Abraços,
Rossine.
