Enhancements To Class Diagram?
Jan 28, 2009I have built a class diagram for a proram i am building in vb, and i need some help to enhance it.The program description:"Modeling Car Parking System Modeling Car Parking System (MCPS) is the software that manages a parking for cars. The dedicated employees in that parking will use this system to control the parking. This software will facilitate the work in the parking and covers most activities performed, such as booking, cashing, and organizing. In the following, we will provide a comprehensive description of the parking (the scope of the system) followed by a description of the system with the functions that will be performed.
The Parking (The scope of the system)The parking consists of two floors, with a capacity of three hundred car places, and opens 24 hours all the week�s days. It has two main control stations; one is located at the entrance gate, and managed by an employee whose main functions are entering data to the system, then providing a receipt to the driver, and the other is located at the exit gate (cashier station), managed by an employee whose main functions are checking the receipt, entering data to the system, cashing, and providing an invoice.
The parking has three barriers, two main barriers are placed at the entrance and exit gates, and the third one is located at the second floor�s gate. They are controlled by using a remote control.When a driver wants to park his car, he has to drive it to the entrance where an employee (receptionist) will enter the car plate number to the system, then prints out a receipt to the driver. This receipt will contain information such as, the car plate number and the entry time. After that, the receptionist will open the barrier to allow the car enters the parking.
Inside the parking, the second floor will be kept empty (closed by the barrier) until the first floor will be full. When the first floor becomes full, the employee will open the barrier to allow the cars to park in the second floor. A driver can park his car in any vacant place in the available floor.When a driver wants to leave the parking, he drives his car to the exit gate and presents the receipt to the employee in the cashier station, who in turn, will check if the number recorded in this receipt (at the entrance) is similar to the real plate number of the car. After that, the employee will enter that number to the system, take the money, provide an invoice to the driver, and finally, open the barrier to allow the car leaves the parking.The list price in the parking, declares that parking a car for an hour costs 3850 LBP, and each extra parking hour will cost 3000 LBP.
Description of the System :The system will operate 24 hours, and will perform the tasks related to the work in the parking. The following scenario will explain what we mean by �will perform the tasks� in the parking.
At the entrance gate, the employee will enter the car plate number to the system as a (driver ID), and select the available floor which is in service from a menu. The system, in its turn, will store these data and additional data such as the time entered, and then issues a receipt including information such as driver ID, entry time, date, and the available floor reference.
At the exit gate, the employee will enter the car plate number (driver ID) to the system which will generate the data related to it, and prints out an invoice including the current time, date, total parking time, and the total amount of money (parking fee); since the parking fee and the duration will automatically be calculated and displayed by the system.
In addition to the tasks which the system will achieve at the entrance and exit gates, it also will provide statistical information such as the total count of cars that exist in the parking at any time, and the number of the vacant or busy parking lots (car places) in each available floor. Also, the simulation which will be part of the system will play a role in managing the parking since it will show an up to date comprehensive scheme of the parking.
The graphical simulation of the car movement flow When a car will enter the parking, and after an employee has implemented all the tasks associated by the entrance such as entering the car plate number, and selecting the available floor, the system will issue a receipt and automatically will lead the user (employee) to the simulation part. The simulation part is a form that contains cars and parking lots as graphical components, when a user click such a button �Drive-in a car� a car will move to occupy an available empty parking lot.
When a car will exit the parking, and after an employee has implemented all the tasks associated by the exit gate such as entering the car plate number, the system will issue a receipt and automatically will lead the user (an employee) again to the simulation part. When a user clicks such a button �Drive-out a car�, the car will leave to parking lot was occupied.

Use A New Class Rather Than Add To An Existing Class?
Feb 27, 2009I have a class called Player in the business layer of my web application.Player class has fields PlayerID, CategoryID and CountryIDA function in Player Class calls a function in PlayerDB Class in the Data Access Layer which in turn calls a stored proc which returns data for PlayerID, CategoryID (foreign key to Category table) and CountryID(foreign key to Country table) from the Player table.I now have a situation where I want to add Country Name and Country Image (url path) to the above call, returning the new fields from the Country table for each CountryID.My question is, do I add the country name and country image as additional fields to the Player class or do I have new classes called Country(BLL) and CountryDB(DAL) and a new stored proc?

View 4 RepliesOpen An Existing VB Class File?
Jun 30, 2011I want to open an existing VB class file, add a few properties and close it again.
Simple enough, I thought: Take the CodeDom, a VBCodeProvider, parse the code (using the Parse-method), then identify the location where I want my stuff added (doubtless using some nifty LINQ expressions), add a bit of code and then have it generated and here we go.
Now I see that Microsoft apparently added the Parse method only for the fun of it but never implemented it.
What's the story here? Can I only generate code from scratch? Is it not possible to load existing code?
How To Compile Single Class Into Existing Project

As you can see it have a different signature from the public method so I think it would be nice to have my method overloading the existing method

C# - Rewriting Existing Functionality In The .NET Base Class Library
Apr 14, 2009Relating to another question I asked yesterday with regards to logging I was introduced to TraceListeners which I'd never come across before and sorely wish I had. I can't count the amount of times I've written loggers needlessly to do this and nobody had ever pointed this out or asked my why I didn't use the built in tools. This leads me to wonder what other features I've overlooked and written into my applications needlessly because of features of .NET that I'm unaware of.
Does anyone else have features of .NET that would've completely changed the way they wrote applications or components of their applications had they only known that .NET already had a built in means of supporting it?
It would be handy if other developers posted scenarios where they frequently come across components or blocks of code that are completely needless in hindsight had the original developer only known of a built in .NET component - such as the TraceListeners that I previously noted.
This doesn't necessarily include newly added features of 3.5 per se, but could if pertinent to the scenario.
Edit - As per previous comments, I'm not really interested in the "Hidden Features" of the language which I agree have been documented before - I'm looking for often overlooked framework components that through my own (or the original developer's) ignorance have written/rewritten their own components/classes/methods needlessly.

VB Class (class File - Not School Class)
Aug 9, 2011so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.

Create A New Class That Inherits From The Base Form Class And Define A New() Method With Parameters?
Oct 1, 2008I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

.NET Multithreading / Calling Invoke On A UI Control From A Class In A Separate Class File?
May 13, 2011Example:
Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Imports System.Threading
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.
