So today I was reading up on a development community website, and I ran across one
of the classic arguments that will ultimately erupt when two or more Windows developers
get together: which is the better language, VB, C# or Managed C++. These arguments
always make me chuckle a bit, because with the .NET Framework it does not make much
of a difference which language you choose since it all gets compiled down to IL
That discussion did remind me of an idea I had at one time, and if any of you adventurous
developers feel like stealing the idea and implementing it yourself, then by all means
steal away. Why do you need to select one language over another, why can’t you use
all of them? I can create a HTML file, and use different languages within that page.
For example, I could use JScript and VB Script at the same time, as so:
Why can’t I do the same with VB.NET, C#, or managed C++? For instance, why can’t I
start Visual Studio, create a blank project, and enter code such as this:
Public Class Class1
public class Class2
string s = “abc”;
public void Function2()
public __gc class Class3
from managed C++”);
There are ways of doing something like this with current technology. I could create
three separate projects, add project to project references, and call across the different
assemblies. But then I need to build three separate projects, create, package, and
install three separate DLLs. I could also create net modules, but then again, you
would have three separate DLLs.
This new model has some other benefits. How many times have you found a sample function
that would work perfectly for your code? If you selected one language (suppose C++)
but the sample code is in another language (for example VB .NET), then you need to
translate the code into the other language. That is not too tough if the code is small,
but if it is a few hundred, or even a few thousand lines, you would spend more time
translating than writing it from scratch (and even cause a number of bugs while doing
it). Not only does it enable better code
sharing, but it also allows better team development. It will allow all the developers
in your group to put all their code in one project, and use whatever language they
want to use without the code being scattered about.
This has not been completely thought through though (say that three times fast). For
example, how does Function3 access the static variable s declared within Class2? Cross-language
data access is not allowed in the HTML version, either, so this is not something new.
The compilers today are type safe, and if the compiler cannot find the type of variable
s, then how can it compile? And why should each function be declared in separate classes?
Why can’t you declare a class, and have Function1, Function2, and Function3 within
the same class, but use different languages? I didn’t say it would be easy, or even
work with the current technology, only that I think it would be an easier way of developing.
