DISC 3371 MIDTERM FALL 2005 Parks

1. (40 points) The VBScript function now returns the current date and time in the form of a string in the format: mm/dd/yyyy hh:mm:ss followed by "AM" or "PM" (e.g., "11/3/2005 11:31:25 AM").

Write the VBScript code that will place a graphical presentation of the current date/time in a SPAN block when the page is loaded. This graphical representation is created by placing a sequence of gif files that represent the characters in the date/time string into the SPAN block. The 15 possible gif files that may be used are named: e0.gif, e1.gif, e2.gif, ... , e9.gif, eslash.gif, ecolon.gif, eam.gif, epm.gif and eblank.gif. The gif files are shown below:

A sample of the desired output is shown below:

The Current Date and Time is:

Assume that the BODY tag contains: onLoad="p1" and the SPAN block has: id="dt_span". Show NO HTML -- just the VBScript for p1.

2. (40 points) Write a javascript program that generates random user passwords. The password contains a mixture of upper case letters, digits and lower case letters. The number of characters of each type (upper case, lower case and digits) is to be entered by the user in text boxes as shown below.

The "upper case" letters appear first, followed by "digits", followed by "lower case" letters.

For "upper case" letters, randomly choose from the 23 character string: "ABCDEFGHJKLMNPRSTUVWXYZ" (No I, O or Q)
For "digits", randomly choose from the 8 character string: "23456789" (No 0 or 1)
For "lower case" letters, randomly choose from the 23 character string: "abcdefghjkmnpqrstuvwxyz" (No i, l, or o)

PASSWORD GENERATOR
Number of Upper Case Letters
Number of Digits
Number of Lower Case Letters
Password Generated

Assume:

the four HTML objects are contained in a form named p2form;
the desired number of "upper case" letters is entered in a textbox named nup;
the desired number of "digits" is entered in a textbox named ndig;
the desired number of "lower case" letters is entered in a textbox named nlow
the textbox for displaying the password is named pwd
the button labeled "GENERATE" has: onClick="p2()"
any character in the password may occur more than once

Do NOT edit the user's input. Show only the javascript for p2 -- Show NO HTML.
