Friday 31st Lecture

Take a look at code for the coffee shop example for next week - lots of new stuff in there that will be useful for the project: Message Boxes, Module-level variables, Try...Catch Blocks, With...End With Blocks etc.

24th October 2008

Today we looked at scope of variables. Read more about this subject in the textbook pages 103-106. Take a look at the coffee shop worked example at the end of chapter 4 to see a multi-procedure project using module-level variables and If statements.

We also covered the .visible and .enabled properties of objects. This will be useful to you in the project (see example in the class share folder). A key aspect of the project will be bringing all the things we have learned so far together to created a robust solution to the problem.

I forgot to mention in class that the project is worth 30% of the marks for the year. If you do well in it, not only will you have learned a lot about VB.Net, but you can pick up a significant amount of the year's marks. If you have any questions, feel free to email me at j.hayes (at) ucc.ie

Enjoy the bank holiday weekend. See you next Friday.

If Statements

Today we looked at If Statements and a Nested If Statement. For next week, write the program code for the Profit/Loss/Breakeven Example. Notes on decisions are in the class share.

Next week I will be assigning the first project for IS1809.

Decisions

Today we will look at decision structures (If statements and Select Case statements) in order to add additional functionality (branching) to our VB.Net projects.

Declaring Variables (Player Statistics Example)

Today we declared our first set of variables (relating to name, appearances, goals and goal per game ratio for a footballer).We also used the ampersand '&' for string concatenation. For next week, I would like to see your version of the project working).

Again, pay close attention to the naming of objects and variables and be careful not to confuse the name property and text property of an object - the name is how VB identifies of the object, the text is what the user sees.
