found this oddity-
copying a vb6 function with optional parameters and pasting it into a vb2003
class, for conversion purposes, it all works fine except that the collapsing
"-" on the LHS goes away, only to return if "Optional" is removed. Strange.
anyone else had this?

One thought: In VB6, you could just say "Optional param As type" and be
done with it, but in VB.NET "Optional parameters must specify a default
value" so if you just copy this valid in VB6) syntax into VB.NET:
Public Sub T(ByVal a As Integer, Optional ByVal g As Integer)
End Sub
you will get a squiggly line under the ), and no - collapsing section,
because it doesn't compile. Change it to eg
Public Sub T(ByVal a As Integer, Optional ByVal g As Integer = 0)
End Sub
and you get your - collapsing section.

The "+" isn't shown as long as there is a compile-time error in your method
declaration. I assume you forgot to assign a value to the optional
parameter, which will fix the problem:
\\\
Public Sub Foo(Optional ByVal Number As Integer = 0)
...
End Sub

Larry,Herfried, yes I thought that was the problem too but even with the
default in place no "-", however after removing the optional parameter
clicking on a different line and then replacing it it worked correctly.

I just picked up a copy of John Robbins' debugging book and started to look
at disassembled code. Anyway, I hate optional Parameters in VB, but I was
checking them out to see what IL is created. I've done this before with
Modules, and saw that <gasp> they behave just like sealed classes with only
static members.
Anyway, it looks like Optional Parameters are nothing but a way to tell the
compiler to write some overloads for you. So, in...

I am trying to create a query that can be loaded as a querydef object
but not having to assign values to the parameters if I don't want to.
Normally when using a parameter query in VBA my code would go something
like this:
dim qry as dao.querydef
set qry = currentdb.querydefs("myquery")
qry.parameters("Par1") = "blah"

Can anyone tell me what the rational is for not supporting optional
arguments.
It is obviously a trivial thing to implement and, since C++ has them, I
would not expect them to be omitted without a good reason.

To make things simpler and better readable I'd make all default parameters

Hi guys,
In the past I have used several time optional parameters in my
function.
But Now I am more inclined to think that they are more dangerous than
useful, and probably better to be avoided.
I'd like to hear your various opinions on this matter.

This is more of a general question, but I didn't know where to post it. Since Java is an example of a language which does this, I thought here would work.
Coming from a C++ background, having used VBA/VB6 quite a bit, and a number of scripting languages with similar traits, like php, I had grown accustomed to optional parameters in my functions.
I recently found out that certain modern languages do not support these, namely Java and...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
