Como aplicar uma senha para abrir um formulário

Oi galera, tudo bem?

Estou com uma dificuldade. Como posso aplicar uma senha ao abrir um formulário no Access 2010.

Desde já agradeço pela informação.

1º crie um módulo e cole o código abaixo dentro e salve o módulo com o nome de Senha_inputboxdk

2º - Cole isso no evento ao abrir do seu formulário:

Dim UsrResposta
UsrResposta = InputBoxDK("Digete a senha", "Senha requerida")
'A mensagem acima entre os parênteses pode ser alterada
If UsrResposta = "123" Then 'este valor entre parenteses é a senha
Else
MsgBox "Senha incorreta", vbCritical, "Senha incorreta"
Cancel = -1
'aqui a mensagem de senha incorreta. Pode alterar
End If
End If

Gilberlanio, tudo bem Brother?

Fiz como você orientou mas não deu certo. As linhas do código em aberto abaixo ficaram em vermelho:

Private Declare Function SetWindowsHookEx Lib "user32" Alias "SetWindowsHookExA" ( _

Private Declare Function UnhookWindowsHookEx Lib "user32" (ByVal hHook As Long) As Long

Dá uma mensagem dizendo que o meu sistema é de 64 bits.

Como adaptar esse código para um sistema de 64 bits?
