The coding are part of the coding in the client program. I have try to restart and shutdown but seems like nothing is happening. I used this
Private Sub tutup_Click() 'To shutdown the computer
sckControlPanel.SendData "Shutdown#"
End Sub
Private Sub restart_Click() 'To restart the computer
sckControlPanel.SendData "Reboot#"
End Sub
I have put in the command to force the window to restart,shutdown but nothing seems to be happening.Also how do i unlock a computer? One more things how do we disable Alt+Crl+Del. The above coding is not that good. Please advise.
