[Resolvido] InputBox com mascara de senha

Olá,

Tenho um form no access que para acessar é necessário digitar uma senha. Eu usei o seguinte código para fazer isso:

Código:

Private Sub Command25_Click()
Dim strRet As String
strRet = InputBox("Enter the password to access Updates", "Password")
If strRet = "1234" Then ' 1234 é sua senha
'Senha correta libera o formulário
DoCmd.OpenForm "Update"
Else
'Senha incorreta fecha a BD
MsgBox "Incorrect Password", vbInformation, "Click OK to continue"
End If

Porém, quando eu digito a senha, dá pra ver qual é a senha que eu estou digitando.

Tem como eu mudar isso para que os caracteres que apareçam sejam bolinhas ou astericos?

Boa tarde Camila...

Private Sub Command25_Click()
Dim strRet As String
StrRet = InputBox("Enter the password to access Updates:", "Password", "******")
If strRet = "1234" Then ' 1234 é sua senha
'Senha correta libera o formulário
DoCmd.OpenForm "Update"
Else
'Senha incorreta fecha a BD
MsgBox "Incorrect Password", vbInformation, "Click OK to continue"
End If

Eu fiz como você sugeriu, mas não deu certo.

Quando eu digito a senha continua aparecendo o número "1234".

Cole este procedimento em um módulo e o nomeei de mdlImputBox:

E no seu código:


InputBoxDK("Enter the password to access Updates", "Password", "******")


Cumprimentos.
