How do I get a "show password" effect in vb.net?
提问by Brayden
I am making an email login program in visual basic 2015 with various options, one of them being the option to show password or not with probably a check box. It is just a simple, standard windows forms application, I am relatively new to it.
我正在使用各种选项在visual basic 2015中制作电子邮件登录程序，其中一个选项是显示密码或不显示密码的选项，可能带有复选框。它只是一个简单的标准 Windows 窗体应用程序，我对它比较陌生。

'Display plain text if and only if check box is checked.
TextBox1.UseSystemPasswordChar = Not CheckBox1.Checked

Set the UseSystemPasswordCharproperty of your TextBoxto Trueto mask the password.
设置UseSystemPasswordChar你的财产TextBox，以True掩盖密码。
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

You have to do couple of changes. Change your password textbox UseSystemPasswordCharto false and the PasswordCharto Char(0). Something like this:
你必须做一些改变。将您的密码文本框更改UseSystemPasswordChar为 false 并更改PasswordChar为Char(0)。像这样的东西：
If chkViewPassword.Checked Then txbPwd.PasswordChar = Convert.ToChar(0) Else txbPwd.PasswordChar = Convert.ToChar("*")
txbSMTPPwd.UseSystemPasswordChar = Not chkViewPassword.Checked
