Interesting VB.NET Intellisense

Hi,

Seems like VB.NET Intellisense and complier does check for method
definitions much. The following code compiles with no errors in VB.NET! (but
of course, trust C# to be strict and perfect :) )

[c#]
public class MyOwnClass
{
public void Print()
{
Console.WriteLi ne("Print");
}
}

static void Main(string[] args)
{
object myObj = new MyOwnClass();
myObj.Print();
}

[VB.NET]
Public Class MyOwnClass
Public Sub Print()
Console.WriteLi ne("Print")
End Sub
End Class

Module Module1

Sub Main()
Dim myObject As Object = New MyOwnClass
myObject.Print( )
End Sub

End Module

I believe i read somehere about VB being dynamin binding or
something....du nno whether this is something to do with it.

Rakesh,

This is something the people who use VBNet do hate in C#, it has many legacy
restrictions from C and that is needed because it does not use intellisense
in the IDE which can help the programmer with the exeption than that C# is
showing some more information (wherefore is the documenter which is not in
VBNet until 2005).

In VBNet does "object.whateve r" mean by default "object.whateve r()" what it
would be in classic C. What can it be else, however it is checked with
background compiling by the IDE in VBNet, a feature that does not exist in
C#.

When you are talking about binding, than has VBNet two possibilities, with
late binding and early binding.

Late binding can be very effective for modeling however not good for real
production software because it can give unpredicted errors. It is easy to
set in VBNet as a option in the IDE to use always option strict on, and than
it is exactly the same as with C#.

I hope this gives some idea's

(When you translate a language by the way, do than not use the style of code
you are used to by your regular code, the sample you showed from VBNet would
be made by a VBNet programmer much simpler).

I don't understand how this feature could be useful - won't this result in
errors that could be easily prevented? For example, if someone misspells a
method name in VB.NET - this would create a run-time exception, whereas this
would be caught @ compile time in C# (much better).

The errors are catched when typing in the IDE directly with VBNet, The VBNet
IDE corrects as well by instance although not directly needed as well all
cases.

There is one argument that this is not a good method; This checking while
typing cost time, so especially on more older computers the C# way of doing
it is than better.

I hope this makes it even more clear.

For me is this a major reason why I am a VBNetter yes. The language
differences itself are very fair and are not a reason for me.

I'm a VB.NETter too. I have done some programming in C# but much prefer the
forgiveability (that might not be a real word) of VB. If I misspell a method
then VB will complain to me that the method does not exist. This is because
I have Option Strict On and Option Explicit On.

If I make a mistake in VB the IDE tells me immediately, C# waits for me to
Build.

Now the main reason that I prefer VB is that it is not case sensitive.
mymethod is exactly the same as myMethod and the IDE will automagically
correct the case for me. C# does not and so I have to spend too much time
correcting case (I'm not a touch typist so I look at the keyboard not the
screen).
If I have 2 different variables/methods I would choose to give them
different names rather than different case, since I find it is much easier
to read back.

What's the difference between myvar, myVar and MyVar? Which one am I
referring to in myMethod? Did I really mean to use MyVar when I used myVar?
It may compile just fine but will give me an error which may be hard to
trace. This is the reason that i would not declare variables using
differering case and so I immediately lose the benefit of Case Sensitivity.

There are things about C# that I do like, but overall I much prefer VB.

Why just give some examples,

This is not a war however I was almost sure you was missing that part of the
checking of typing in VBNet so that I tried to explain for you.

The first time I used C# (I started with VBNet) I was expecting that it was
there as well. So probably your starting message was because you did not
know that this was in VBNet.

However explain to use why in your opinion C# is more OOP than VBNet, I am
currious about it because it is really again an message we see seldom in
this dotNet newsgroups, even not when people are telling why the one
language is better than the other (what I do not, I am only talking about
the IDE which I prefer).

How is it more OOP like?
I don't believe that VB is better than C# or vice versa, I just much prefer
VB. Maybe I am swayed by my VBClassic background, but I don't think so.

Cor and Mick,

I feel it's more OOPs like because OOPs started with c++ and c# derives it's
most of it's syntax from c++ and java...most of the keywords map directly
with what OOPs states....with VB.NET, i feel it's more like an 'add-on' to an
existing set of keywords, rather than pure thing u know...

The point i want to bring here is that as C# was developed from scratch
based on OOPs and all, it's seeminlgy very usable.

Don't you feel so?
