Question

我正在使用各种选项在visual basic 2015中制作电子邮件登录程序，其中一个是显示密码的选项，可能是一个复选框。它只是一个简单的标准Windows窗体应用程序，我比较新。

Private Sub CheckBox1_CheckedChanged(sender As Object, e As EventArgs) Handles CheckBox1.CheckedChanged

'Display plain text if and only if check box is checked.

TextBox1.UseSystemPasswordChar = Not CheckBox1.Checked

End Sub

Answer 1

将UseSystemPasswordChar的{{1}}属性设置为TextBox以屏蔽密码。

True

Answer 2

Private Sub txtPassword_MouseHover(sender As Object, e As EventArgs) Handles txtPassword.MouseHover
    txtPassword.PasswordChar = ""
End Sub

Private Sub txtPassword_MouseLeave(sender As Object, e As EventArgs) Handles txtPassword.MouseLeave
    txtPassword.PasswordChar = "*"
End Sub

Answer 3

您必须进行一些更改。将您的密码文本框UseSystemPasswordChar更改为false，将PasswordChar更改为Char(0)。像这样：

If chkViewPassword.Checked Then txbPwd.PasswordChar = Convert.ToChar(0) Else txbPwd.PasswordChar = Convert.ToChar("*")
    txbSMTPPwd.UseSystemPasswordChar = Not chkViewPassword.Checked

如何在vb.net中获得“显示密码”效果？
