I am working with PHP and FPDF to generate a PDF invoice. The designers have created a couple of very helpful documents, there are three total. The first is a mockup of the invoice. The second shows fonts, font sizes, and font colors. The last document show the positioning of all elements on the invoice. My only problem, is that the document was made with pixels at a resolution of 300 DPI rather than in millimeters. Anyone that is familiar with FPDF will know that PDF’s created with FPDF can not be generated with pixels in mind. PDF documents in FPDF can only use point (pt), millimeteres (mm), centimeters (cm), or inches (in). Read the rest of this entry »

Rounding to the nearest half dollor (or quarter dollar)

June 18th, 2008

One of my recent projects required that I round the price I was calculating to the nearest half dollar. This started out at a pain. Rounding to the floor, or to the ceiling, or normal rounding is quite easy. But I have never had to round to the nearest half dollar.

C# Image Server Client (Using XML for the application protocol)

June 5th, 2008

Our assignment in class this week was to create a network based client that would connect to the teachers Image Server and make requests via XML for information such as getting a category list, getting and image list, and ultimately, getting the image itself. There were a few different things that needed to be handled to make this work properly. Granted, this isn’t the best code in the word, since the summer semester is so short, but it does work. For it to run properly, you have to be connected to the VPN at UVU. Read the rest of this entry »

C# Database Connection Example Program

May 29th, 2008

We were given a programming assignment in my network programming class that is defined as below. This is my solution to the assignment. I know it isn’t the best code in the world, but it works and will hopefully help someone else who is in need of knowing how to connect to a MSQL database using C#.

Write a program that will connect to the Image Database, list the categories from the category table then when the user selects a category in the list, show the name of all images in that category in another list box. To access the database, you will need to be logged into CSEVPN. Read the rest of this entry »

May 21st, 2008

In my network programming class CS3670 at UVU (UVSC) we had an assignment to write a multicast chat program that would allow everyone in the class talk in the same chat window. This was used to show that we were able to use the multicast addresses and to also demonstrate our use of the UDP client libraries. Here is my solution: Read the rest of this entry »
