Jaybee V.

c# developer (as stated). Currently working for a company where I write Math education software. (Gr 1 - 7, South African syllabus.) Based on Windows Forms. I use a 3 tier(Model, Presenter, View) structure. I've put in a registration mechanism that does not allow you to use the same registration on another computer.... nor allow you to copy over the registration information to another computer. I've also put the registration security into the controls(That holds the different types of exercises), so it can not be used by another developer; passing it as his own. The software, generates the questions and displays them at random. The questions are not pulled of a list. So there really is no saying WHEN you will receive a particular question again. (This excludes Data Handling and Word sums.) The software is also written in 2 languages, Afrikaans and English. I am the only developer in the company. I've joined freelancer for extra income.
