Hi all,
My question is on Username/password authentication
for Web Service on Page 643 ( Beginning ASP.NET 1.1 with VB.NET 2003
). When I try to enter the password ,the whole text appears in the textbox. For example, if the password is "hai" then "hai" appears in the textbox instead of "***". How can I solve this problem
Please help me.

Thank you

Change the "Textmode" property of password control to password.

Hi Prakash,

I know what u mean. I thought changing the "TextMode " property to "password" is to ".aspx" files. Web services are are ".amsx" files.
I may be wrong.
For example, in Java one can easily use the password mask technoliogy, setEchoChar('*'):
      TextField password = new TextField()
                 password.setEchoChar('*')

I am just wondering if there is this type of technology in VB.
The code is wriiten below, How can U fix the problem? Please help

A standard Web application usually uses Forms security. There is a login page that a user can go to, and once they have enetered a ISERID and Password, they are allowed access to the site. There is no user interface with Web Services, so that option is not available to me either.
