GET_PASSWORD

Syntax:

GET_PASSWORD(N mapnr, N fieldnr)
Return Value:

C password
Description:

GET_PASSWORD prompts the user for a password in the standard DP4 password format. The password is typed into a hidden field and it is not possible to move past the field

 

There are two points to note when using get_password():

 
  1. Take care when including get_password() in an expression:
    if ask_password then get_password(100, 1) else " "
    The password will always be requested, even when ask_password is FALSE
  2. If you use get_password() in an interactive database procedure, you are recommended to use the following formula:
    if false then $ else get_password(100,1)
    This formula prevents the password function form being called more than once. You may need to do this where database access causes a pre display. The above formula references the field itself, and so is not evaluated in a pre display

 

The GET_PASSWORD function uses the specified map and field for data entry. The returned value is the entered password or NULL if the user pressed <Escape>
Example:

get_password(100,1)
{pops up map mapnr, and returns the password entered in field fieldnr}
