Website update

March 4, 2014 Mr Stratton

I have updated the departmental area on the school website. This is a more static web site and as such I have put the notes here. You will also find the presentations there.

I will be posting a video on how to use Scholar to plan your revision. It will be based on this post.

Blank spaces on Blog.

March 2, 2014 Mr Stratton

If you are wondering what the blank spaces are on some of the posts you might want to switch to Internet Explorer and view the unsecured content. The are videos and flash files that are using HTTP rather than HTTPS.

Past paper check list

March 2, 2014 Mr Stratton

I have updated this and I will give you a paper copy on Tuesday. Use it with traffic light stickers/high lighters, to record your progress. The Section 2 questions have not been broken down in part or the spreadsheet would have gotten out of hand. However, feel free to create one yourself and post me a copy 🙂

I have also posted the sample question paper and the Section 1, 2 & 3 PDFs in the past papers page (at top of page). There are no marking schemes on the blog so you will need to look elsewhere for the answers.

Module Libraries

February 25, 2014 Mr Stratton

A module library contains a set of pre written and pre tested procedures that can be used by the main program to complete its tasks. This has the advantage of speeding up the development of the software.

Some companies also provide access to module libraries they maintain to allow you to work with their products. i.e. Google

Case Statement

February 25, 2014 Mr Stratton

The case statement is used to make complex selection easier. It is used with one variable i.e

Case Age
>=21: Display over 21
>=18: Display over 18
<18: Display Under 18

Macros and Scripts

February 25, 2014 Mr Stratton

A lot of people get these two terms mixed up.

A script is a piece of code that is written or edited and can be attached to a button or ran directly.
A Macro on the other hand is a sequence of steps that is recorded from the users actions.

They are very easy to mix up so read any questions carefully.

February 25, 2014 Mr Stratton

A declarative language makes use of facts and rules to solve the problem. Prolog is an example of a declarative language.

Arrays

February 25, 2014 Mr Stratton

An array is a data structure that can store a number of pieces of data of the same type. While a normal variable can only store one piece of data at a time an array can store more than one.

Array need to be setup before they are used in VB, you also need to specify the size of the array in advance. i.e. DIM LastName(10) as String would create a ten item array of type String.
