Syntax Question?

[N. Demos]

In the ASP.Net (VB.Net) book I'm reading (learning from) the syntax used
for class inheritance uses a colon between the class declaration and the
inheritance statement.

EX:
Public Class MyClassName : Inherits ParentClassName
Elsewhere, I have seen the following syntax without the colon operator.

Public Class MyClassName
Inherits ParentClassName

I've had no problems (that I know of) with either sytax style when
compling and running code.

Which is the correct syntax, or are both correct? Thanks for your time.

The ":" syntax in VB.NET is the line break (or continuation) character. VB.NET
wants Inherits on the next line, but the : is a shortcut to doing that. They
are equivalent.

It's strange - most developers (probably even the author of the book you
mention) would say that joining lines with ":" is poor style, but since the
colon is coincidentally the same operator used for signifying inheritance in
C#, many of the same developers use the line join operator there in VB
without even thinking about it.

David, Brock,
Thanks for the info. What about the old VB line continuation character
"_" (underscore). Are there two line continuation characters now?

Disregard this, I now realize these do not perform the same function.

Yes, a little confusing :) IMHO use of : in VB.NET is poor practice as
it leads to hard-to-follow code. It's too easy to slip some code in at
the end of a line that someone else could 'skip over', as we're usually
used to 1 command per line (or 1 command split across multiple lines at
most).

Some would argue differently for such a 'minor' thing like marking
inheritance, but hey, believe me after 8 years, I live by 'practice
makes perfect' :)
