password should not be username

Hi,

Use this function to validate that the password should not be username.

Public Function PassLikUsername(ByVal uName as String, ByVal pWord as String) as Boolean

Dim retVal as Boolean =  False



If uName = pWord then

    retVal = True

End If

Return retVal

End Function

Usage:

If PassLikUsername(strUsername, strPass) then

     Msgbox("Cannot use password as username !!")

End if

Hope this Helps.

Hi,
Why dont you use Compare Validator or javascript to check username and password in front end only.

Thanks,
Sanjay

@Naraayanan:
if I enter
User Name: test
Password: Test
ur code will not catch the difference.
Solution:
Convert both the "User Name" and "Password" fields' text value into lower case or uppercase then compare.

Hi,

You can use comapare validator or compare textboxes value by C#
i.e
if(txt_UserName.Text==txt_Password.Text)
{
Response.Write("UserName and password can't be same);
}
else
{
Response.Write("Ok");
}

I think the best way is to use compare validator for both text boxes..

I think its easy to edit the Java Script at client side and bypass the validation.
again CompareValidator can't catch if the text case changed for e.g,
User Name: test ; Password: Test
Use the below code snippet on the button click event,
if (txtUSerName.Text.ToUpper() == txtPassword.Text.ToUpper())
lblError.Text = "ERROR:Username & Password can't be identical";
else
lblError.Text = "Logged in successfully";

Enter "test" (same value) in both User Name and Password field, CompareValidator won't stop
CompareValidator is not the solution in this case.
We use CompareValidator to check Password and Repeat Password field.
