Ativando o Caps lock via código

1a. Parte:
Insira o seguinte código nas declarações gerais de um módulo .BAS

Public Const VK_CAPITAL = &H14
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
Em um form, coloque 3 command buttons (cmdToggle, cmdTurnOff, cmdTurnOff) e
uma label. Coloque o seguinte código no form:

Private Function CapsLock() As Integer
CapsLock = GetKeyState(VK_CAPITAL) And 1 = 1
End Function

Private Sub Form_Load()
If CapsLock() = 1 Then Label1 = “On” Else Label1 = “Off”
End Sub

Private Sub cmdToggle_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_CAPITAL) = IIf(kbArray.kbByte(VK_CAPITAL) = 1, 0, 1)

SetKeyboardState kbArray
Label1 = IIf(CapsLock() = 1, “On”, “Off”)
End Sub

Private Sub cmdTurnOn_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_CAPITAL) = 1
SetKeyboardState kbArray
Label1 = IIf(CapsLock() = 1, “On”, “Off”)
End Sub

Private Sub cmdTurnOff_Click()
GetKeyboardState kbArray
kbArray.kbByte(VK_CAPITAL) = 0
SetKeyboardState kbArray
Label1 = IIf(CapsLock() = 1, “On”, “Off”)
End Sub
