Program: What Time Do I Leave Friday

Aug 14th, 2006 by Brian A. Thomas

Last Update 9 September 2006.
What Time Do I Leave Friday is a program I created in C# using Visual C# 2005 Express Edition. It is the first "semi-practical" program I have made. (I say "semi-practical" as I don't have a way of using it at work, since I don't have a laptop.)

Simply stated, the program is designed for people who are mostly on Flex Time and want to find out when they should leave on their last day of the work week. The user enters the hours they worked so far, the time they came in that day, a lunch if they take one, and it will give them the time to leave.
You can get it from here.
I will post the code to it's own page to keep this page from getting too far out of hand.
Here are some screenshots:
The main screen:
Mian screen of my program, What Time Do I Leave Friday
Here the user enters the total hours they worked so far this week (using the action menu they can change the standard work week hours from 40:00), they also enter the time they got in Friday (or whatever their last day of work is) and a lunch if applicable. It will then display what time they are to leave Friday.

Here is the lunch screen:
Lunch screen of my program, What Time Do I Leave Friday
Here the user can choose to enter their lunch time (for example 0:30 for 30 minutes) or put in their time out to and in from lunch.

Here is the main screen after being used (I typically don't take a lunch, but for this example I entered one):
Main screen in use, after entering lunch and other information for my program, What Time Do I Leave Friday

Here is some of the code (I don't present the code for the designer since I figure it isn't necessary, it should be easy enough to figure it out from the screenshots, the program itself and the code below). The code is presented in alphabetical order.

Changes Log:
9 September 2006 - Minor changes to the Validator class. Semi-major change to the main window itself. The program now checks if the user entered a decimal time in one of the two main text boxes, if so, a message box comes up to be sure that is what they wanted to enter. I probably didn't handle that one the best way.

This is the Convert Time class that easily enough converts the time from one format to another for use in the program.
