This uses Inheritance

Im am doing inheritance on the console line, and well all is semi ok. But what im confused on is how do this in a windows design.

I am trying to complete something, but I dont even know where to start.

I was hoping someone could help me. Here are what I need for classes. And what they have to do. of course this all posts up on a listbox.

Ive tried this with console and for the most part i got it working, but it was static info in the code, but the same setup in windows i have no clue.

The base class will be Vehicle. The Car and Truck classes will inherit from the Vehicle class. The Vehicle class will be composed of an object of the FuelTank class. The FuelTank class has 2 attribute variables: (mTankCapacity and mCurrentValue).

In addition to the FuelTank object, the attribute variables of the Vehicle class are: mVehID, mDesc, mOdometer, and mMPG. In addition to setting up properties for the variables as needed, the Vehicle class has the following methods: AddFuel() - receives the amount of fuel to be added to the tank and adds that to the tank if the tank will hold it. If it will, it returns a true; otherwise, a false. FillTank() – fills the tank and returns a string indicating the amount of gallons added to the tank.

The attribute variable of the Car class is mNumRiders. The methods of the Car class are: getMPG() – a method that calculates the current MPG. The MPG is reduced by 2% for every rider over 1. (For example if the car's mpg is 28.5 and there are 5 riders, the current mpg is 26.22). MoveForward() – receives the mileage to move forward. The method determines if there is enough fuel to make the trip. If not, it returns false. If there is enough fuel to make the trip, the mileage is added to the odometer and the gas tank is reduced by the amount of gas needed for the trip.

The attribute variable of the Truck class is mLoadLbs. The methods of the Truck class are: getMPG() – a method that calculates the current MPG. The MPG is reduced by 3% for every thousand pounds if the load is >= 1,000 pounds. For example if the truck's mpg is 13.4 and is loaded with 4000 pounds, the current mpg is 11.79. Another example is if the truck's mpg is 13.4 loaded with 500 pounts, the current mpg is 13.4. MoveForward() – receives the mileage to move forward. The method determines if there is enough fuel to make the trip. If not, it returns false. If there is enough fuel to make the trip, the mileage is added to the odometer, the gas tank is reduced by the amount of gas needed for the trip, and the method returns true.

So thats the classes, go give a visual refrence there is a listbox, a move forward button and a add fuel button.

I would honestly love the help on where to go with this, I am so lost but yet i really need to see a sample of this coded. All the samples I have are in console (look around the web and they all are) I would just like to see a sample like this in a windows format, seeing how its way more confusing.

Please I am really looking for help, if you wish to email me then fine, or something. As long as i can figure out how this dumb program goes. This is what you get when you get a lab book to teach your self but no teacher edition. *sigh* I look forward to your help.

Hmm, this sounds like fun. :) Lucky you.

I would love to see the code for the console & / or pseudo-code you have for the windows side. From there we can use that as a basis to create a windows versions, which by that I believe you mean a Windows Form Version? Suggestion: You would have a list box displaying the Truck or Vehicle attributes VehicleID (bound column), Description, Miles Per Gallon

Then you could tie the FillTank() / AddFuel () Methods to a button, when pressed adds the fuel and a message box or a text box could display the amount added.

Parent Class = Vehicle
-Common characteristics of a vehicle are
Description
ID
Odometer Value
Type
Percent Decline in MPG per Rider
Child Class(es) which inherit from the Parent
Type : Truck or Car
Description
Odometer Value
Percent Decline in MPG per Rider
mpg
Tank Size
Current Fuel Level
Max number of Riders


Etc..

or at least something along that line.

So once we get some code to work worth, this should come together nicely.

Look forward to getting your reply with code

Edit: This question would be a good thread to turn into a tutorial to teach others about inheritence.

Yes it is the forum window. The code thus far isnt much. I have done something somewhat similar to to this, but in console. And thats all my blasted book teachs is how to work in console yet I have this im working on and it wants it in windows form. It says there is little to no difference but I am not agreeing with that statement.

I think i just need to see a sample of a windows form based inheritance program that has a list box to display the outut and i should understand it.

Requardless ill put up the code in a bit.

Well this is what I have thus far, dont even know if im going the right way with this.

Cool. I am off in an hour and have a long weekend for doing home reno's. I will work on this with you over the weekend... sound good? I have no development apps here at work, so I will help you piece this thing together.

Helps me get a little more up to speed on my C# as well. hehe.

And the details of being similar to the console is somewhat true. instead of console.writeline's you will be setting the display values in a listbox.

Fear not... I will gladly add what help I can.

good to hear.

I assume that everyone feels that I want this project done, far from the truth. I couldnt get anwhere if I did this. I think its the fact that theres another issue and thats forum 1 where as console it would not exist seeing how theres no buttons or anything else.

Maybe if someone can come up with a window form sample of the following

Pet supper class. And now the following. A cat "is a" pet with name(string) and cat_color(string)

and a Pet "has a" trick_id(int) and desc(string).

It displays on a list box

I guess if someone could code that up with a button to edit which trick it can do, I should be able to see whats going on. This way I can see the "is a" and "has a" in effect. This is what i get for trying to learn programming in my 20's :( Everyone else i speak to has been working on a type of programing since like 8. Oh well, im determined.

After i get this all sorted, ill be back with how to control the info on the screen. But right now i just want all the classes to talk and work.

Well off to english class

Well ill be in Sunday from 11am - 5am (central time) Monday. I look forward to seing this forum for help.

Well off to bed

The start of what I have.... working on it when I have time...

Wow it didnt even inform me about this update, I would have sat down with you and gotten help. Ive been pulling my hair out for weeks now. This windows form is killing me. I made an 87 on the test, but im lost here.

What I have and what doesnt work. They erroring I take it needs to be in the car class when it chacks, but it doesnt work. If i put it at the button it works :cry:. As you can see I commented it out. And when this does work, it updates the load pounds and the people, but doesnt update the mileage which is based off that?! Oh god help... This is almost worth shooting my self in the foot over
