Hey, everybody.
I just "upgraded" to VB.NET, boy has it gotten better. My real background is VB6, but I also know C++ which has something that I really appreciate -- overloaded operators. So, can VB.NET overload operators?
Please say "yes"! Please say "yes"!
I don't want to search for it myself because I'll deny it if I don't "find" something about overloading operators. I want someone to say "No overloaded operators in VB.NET" for me to believe it.
**crossing fingers**
I don't believe this is available in VB.Net (I haven't seen it yet, but I admit I haven't looked to hard....because of the statement below)
Good news is that C# does support operator overloading. Since you have some background in C++, you shouldn't have a hard time developing a C# app (assembly) at all, and it uses the same framework that VB.Net does. Even better news... if you just have to overload an operator for a couple classes, you can do that development in C# and compile it to a assembly. Then in your VB.Net project, you can reference that assembly, and call and use it without any hastles. The beauty of .Net....
Now that's beautiful!
Yeah I know C++ and all and I can easily convert to C#, but for some reason, I find it easier for Windows programs (or mini-programs) like mine to use VB. I actually tried to program Windows apps in C++ -- such a hastle, actually. VB takes care of a lot of stuff for me (Paint() or Repaint(), Terminate(), CreateWindow(), etc.). I don't know, but is that also the case for C#? In VB, just click New Form, and you got yourself a form and it's easier to interact among controls. C# too? I hope so, I'd love to convert to C#.
C# is awesome. I learned it first before VB.Net (although I knew VB6 before .net came along). It is just as easy to use as VB.Net in my opinion. There are small differences, but if you are ok with C++, you won't have a problem. It is more strict than VB.Net is, but the functionality is the same. You can drag controls on the form, and do all the stuff you do in VB.Net. As a matter of fact, most code created in C# will compile to the same IL as VB.Net, and you will notice the code is the same, just a different syntax. If you are comfortable with the ';' at the end of statements, and the {} for code blocks, you won't have a problem.
Here is a link I found. It seems that my earlier statement might not be totally correct as far as the interoperability is concerned:

I will try to find more on this issue, and if there is more, I will post what I find.
Ok, it looks like if you overload the == operator, vb.net can't handle it because it doesn't use the operator (but it supports the .Equals() method, which you should implement if it will be called from a vb.net app). But, if you overloaded the + or - operator, it would probably work out just like you expect. I guess if the operators used in C# are the same used in VB.Net, it would be ok. Other difference that pops into my mind is the not equals operator:
<> vb.net
!= C#
That is some great info. Thanks a bunch, hellswraith.
Yeah, I actually prefer the ";" and "{ }" syntax than VB.NET's (I know, such a paradox, me liking VB's functionality but not the syntax).
As a matter of fact, I'm up for a small project right now, I should give C# a try.
From the link you gave me above. A question arises:
In C++ you can overload the "=" (I'm not talking about "=="), but in C# you can't? That's odd! Unless it wasn't enlisted.
That's true.
Have you actually tried to do that before? It sounds like a working idea, but a lot of doubts come up.
I'm not so serious about doing it right now, I was just talking in general, cos I found a lot of flexibility and new features in VB.NET, I though OP's (overloaded operators) are there, too.
I'm pretty sure operator overloading will be in VB.NET in the next version. Although with your background it sounds like C# is the way to go for you. (I can't believe I just said that)
Very Funny! ;)Quote:

My next project (year long..) is in VB.NET, so I'm coming back to the dark side! :wave:
Now, I need to pick up a VB.NET book, any recommendations?
The best reference book I think is Programming in VB.NET by Francesco Balena (http://www.amazon.com/exec/obidos/tg...glance&s=books), but I bet you wont even need a book. After a few days or a week you'll probably adapt to the syntax changes.
You don't need a vb.net book. I had to do a project in VB.Net and it was so simple to get back into. If you know C#, then VB.Net is not a problem (that is if you have vb6 experience, which you do).Quote:

What I worry about is how easy VB.Net is to program with because of the implicit casting and what not. I feel like I am so dirty when I do it...lol. I want to go back to C# as fast as possible.
in vb.net you dont need to cast types?Quote:

Why would you say that?Quote:

the C# code:
int i = 10;
while(i)
i--;
will generate a compile error.
Am I correct on that?
yes it doesnt allow it, and i think its good because they're different types
Yup, Whidbey supports operator overloading in VB.Quote:

:)
but it wont support anonimous methods and generic types like C#Quote:

:wave: :wave:
It will have generics but not anonymous methods, although Vb will also have edit & continue and C# wont. :D
Actually I don't really miss edit & continue anymore, but I guess it will be nice to have it back.
I was pretty sure Option Strict disallowed implicit casting in VB.Net.Quote:

On a side note, Whidbey looks good:
Operator overloading and COMMENT SUMMARIES! YEH!@!
I wonder what syntax that will follow?
VB Code:
Any guesses?
I think I read some where that it was something like @ or !@ for the comments.
I found my source, according to this guy its '@:
