Insira o seguinte código nas declrações gerais de um módulo .BAS

Public Const VK_NUMLOCK = &H90
Public Type KeyboardBytes
kbByte(0 To 255) As Byte
End Type

Public kbArray As KeyboardBytes

Public Declare Function GetKeyState Lib “user32” (ByVal nVirtKey
As Long) As Long

Public Declare Function GetKeyboardState Lib “user32” (kbArray As
KeyboardBytes) As Long

Public Declare Function SetKeyboardState Lib “user32” (kbArray As
KeyboardBytes) As Long

2a. Parte:
Crie um form e adicione 3 botões (cmdToggle, cmdTurnOn, cmdTurnOff) e um label.
Adicione o seguinte código no Form:

Private Sub cmdToggle_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_NUMLOCK) = IIf(kbArray.kbByte(VK_NUMLOCK) = 1, 0, 1)
SetKeyboardState kbArray
End Sub

Private Sub cmdTurnOn_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_NUMLOCK) = 1
SetKeyboardState kbArray
End Sub

Private Sub cmdTurnOff_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_NUMLOCK) = 0
SetKeyboardState kbArray
End Sub
