Password mask issue

[mehm...@yahoo.com]

I am trying to create a login panel for test purposes, and it opens
whenever the Test GUI is first opened and it requests a valid username
and password entry before opening the test GUI. I am using the
pwctrl.fp and the PasswordCtrl_ConvertFromString command to mask the
password string in the password entry text box, but the password is
not getting masked with the "*" character as I was expecting. I tried
following the password example project, but with no success. I have
attached the code snippets to see if anyone can point out the error in
my ways. Thanks for any help.

I found that I had to include the "PasswordCtrl_ConvertFromString"
inside the Callback function for it to work, it doesn't work if it's
located outside of the Callback function.
