Controlling the Monitor or Graphic Cards...

[Ali Rizwan]

Hi all,
I don know how windows turn monitor or harddisk off??? I want to add same feature in my app so that my app can be a power saving app for laptops. I want to use different poweschemes as we do in Explorer.

Bytheway is this controlled by the explorere or by any service???
I think it is controlled by explorer... Plz correct me if i m wrong. Other wise i dont need to add this feature.....

Thanx

i am also confused, u can try by this code

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Any) As Long
Const SC_MONITORPOWER = &HF170&
Const MON_OFF = 2&
Const WM_SYSCOMMAND = &H112

Private Sub Form_Load() 
SendMessage Me.hWnd, WM_SYSCOMMAND, SC_MONITORPOWER, MON_OFF
End Sub
