A large project I’ve been working on as of late has many moving parts. It allowed a lot of dynamic edits that utilized AJAX for sending dynamic information to and from a database. When errors occurred it was alright for me, because I could debug them however what it came the client… Well let’s just say they were convinced that with these errors their computer was going to spontaneous combust.
I’ll admit it now that I was a little lazy when developing some of the classes. I went back and modified them so that they would implement exception handling, only I went one step further and used custom exception handling so that I could log any errors that may occur.
Within this posting, im going to create a class that will have errors, and I’ll also create a custom exception class that will catch any of these errors and log them to a file

When programming in any language I find that there are always several things that no matter how hard I try to remember will never stick. One thing as of late has been using images within objective-c and iPhone development.

Learning Objective-C coupled with the Interface Builder, I found that using a UIImageHolder, or UITextLabel, or even the UIScrollBar came more and more simple each time I used them. I had my laptop with a full battery, a fresh piece of paper to scribble on and I was ready to tackle a Navigation-based Application.
Now this wasn’t a hard feat, but it wasn’t an one easy either. I feel I have a good foot in the door with this, but far from a “pro” status.

While sitting in my Objective-C class learning about the Tab Bar Application and it’s uses our teacher brought up a point in that Apple’s pre-made Tab Bar Application, is good… but not great. The problem is that it starts you up with two views (which is good), However the first view is the main controller. The second view has it’s own controller assigned to it. After a little research and a quick modification to the Tab Bar Application I was able to create my own template that I now use for Tab Bar projects.

It’s been a short time since I’ve gotten anything written, this was due to work being busy, a few small side projects, school projects and exams, summer starting and well - a new love. This love however can be bought with money and it involves selling a bit of your soul.
After waiting a year I was finally able to get a iPhone. 3Gs at that! This quickly pulled my interest away from my every day languages and set me on a course to learn Objective-C.

I was tasked with a project at work in which I had to build a site that would be quite dynamic. The problem however was that I could not use a database to hold information. What I did (and something I would avoid if I could) was create a class that looks within a folder thats specified and builds an array off the files within the folder.

A few weeks ago I had wrote Arrays and Loops with php [Level 1]. This topic is expanding on that idea. I’ll be covering more complex array examples using 2D multidimensional arrays.

Way back when I started programming there were two things I just could not wrap my head around. Unfortunately they fell hand in hand which made doing an alternative quote tedious. Loops and arrays were nightmares. This post is outlines a few small pointers I’ve picked up along the way.

I tend to do a lot of work with database entry through PHP forums. Over time I’ve seen nemorous ways in which someone will enter their phone number.

Creating a basic Java UI can be a little overwhelming, but once you understand what’s going on there is not a lot to it. This post is about the Java User Interface and components within it. Today i’ll be covering:
- Creating a JFrame
- Adding a menu bar
- Adding mnemonics
- Adding key strokes
- Adding a popup ‘about’ window
