It's pretty strange starting with OOP and C++ without C

Maybe they'll start with the C part first. Just make sure it's an intro class and you'll be fine.

actually it is C++ only.
and it's intro class.
here, in this college, courses are already mapped for each major.
so, there is almost no chance that you will take something unnecessary or out of order.

At UCLA CS, they have 2 main courses: CS 31 and 32. 31 starts with basic programming with C/C++ (much like what you would do with BASIC) and then CS 32 does the OOP stuff. You won't have much trouble understanding OOP since Visual Basic is all object oriented !!! (as opposed to BASIC, QuickBasic, GWBasic, and all the older ones).

Sip jan, i remember learning that VB is NOT object oriented programming language.
they say it is object-based, because it does not fully support hirarchy, so it's not OOP language.

i just looked over future terms' scheduals, and there are two more courses that will teach C/C++. they are called OOP II and Advanced Programming With C.
the one that i'm going to take now is called OOP I.

besides programming languages, we also have a lot of System Analysis classes and Database classes.

some suggest that those classes are going to be much interesting, and that it would be wise to master those areas more than solely become a programmer.

what do you guys think?

Sip, VB is not oop. In advanced VB you can pretty much write apps that are very close to being oops apps, but VB fundamentally is not.

Harut, System analysis is okay. I found it interesting, but it is now great, however I personally love database coding and admin and working with HUGE databases. It is fun.

SQL is a very easy and basic language, but you can do miracles with it.

DBA work is very cool as well.

Also, I would be scared to jump into OOP with C/C++ without having a good foundation in C. I had 2-3 years of C knowledge and experience when I had to first learn C++ and it was a challenge.

Granted, VB is not trully OOP but it follows the same philosophy. You basically deal with objects each having properties (data), methods (functions) ... on top of that you have event-based control.

In my experience, people who know VB can grasp OOP much much easier than people who start off (and spend years) with pure functional languages such as C. In any case, I am not a big fan of pure OOP

i'm surprised!!!

listen what my VB professor said just yersterday, during the last meeting before final.

as he summed up the results of the term and told us what we should have learned from this course, he said something like this:

"this course was not designed to teach you VB programming language. we did not attampt to make to a VB programmers. the main objective of the course was to introduce to us the basic concepts of the programming. VB was chosen for this course only because it is easy language and it is easy to show the fundamentals of the programming to newcomers".

i was sort of disappointed that i didn't know this before.
parzvum a, we might take real VB course later.

and what should i do now? stop spending my time on VB and start concantrating on C++, or along C++ i also should keep studing VB?

i'm all confused now.

Harut jan, the more you know the better!

Down the road, it is good to concentrate on one but learn a bit of everything to get a good idea of how things work. Later on, you'll realize that VB, C++, Pascal, Java, Eifel, blah, blah, are basically the same! They all fall into the realm of "context free" languages that work great for "programming" the type of computers we have.

The way you write each will seem different at first, and they all have some specific differences but basically they are the same.

So I'd say learn a bit of both (or others like Java as well) and then decide which one you like.

VB is great for making business like applications. C/C++ on the other hand, is more general purpose and can be used for anything, especially if you want speed. It also gives the programmer much more control (over everything) than VB. Java was geared more towards the web but now it is becomming a very general purpose language.

I don't like Java much and I don't believe in it. The initial commercials sounded great but it just adds too much overhead compared to C/C++. Also, industry backing (like Microsoft) will have a big impact on what will happen to Java but the way Microsoft is pushing C# (C-sharp) and C/C++, I think they are here to stay for a while ... also remember that almost all of UNIX/Linux/Windows is written in C, so C will be here for a long long time.

I use Delphi (http://www.borland.com/delphi) most of the time and would suggest you to take a look at it. It's not as popular in the US as in the Europe but this is only because of the marketing issues.

i don't know any language yet, except a bit of VB.

in any ways i hope i'll make the correct desision.

yesterday i picked up my books for coming term. two of which are "C++ How To Program" from Deitel & Deitel, and "Object-Oriented Programming Using C++" from Course Technology.

i briefly went over the intros, and somewhere there it mentions that link. it says we can download a free copy of Borland C++ from there.
i haven't checked it out yet. i'll do it now.

but i don't understand one thing.
does it matter which compiter i use? isn't C++ C++ whatever i use it with?

i got Visual Studio 6. is it good or bad?

guys, i need help with VB. i'm writing a small program for final. but i want to be a little fancy.

i have wrote this.

quote:
Private Sub cmbResult_Change()
Dim intLoop As Integer
Dim intLenght As Integer
intLenght = Len(cmbResult.Text)
For intLoop = cmbResult.ListCount - 1 To 0 Step -1
If intLenght = Left(cmbResult.List(intLenght)) Then
?????????????
End If
End Sub


what should i put instead of the question marks to set focus to a particular item in the list.

can anybody help, please?
thank you

Dim intLenght As Integer

intLenght = Len(cmbResult.Text)
For intLoop = cmbResult.ListCount - 1 To 0 Step -1

What is the purpose of this sub?
There are 2 ways to make an item selected
1. listbox has a property that stores the selected item's index. you can change this property and assign the correct value.
2. list items have boolean property 'selected' which is true for the selected item. Assign true to that item's 'selected' property and it'll become selected.

I'm not sure about the exact syntax in VB.
