I've dabbled in "Optional" over the last few days and think I'm coming down
against using it.
Seems to me like it makes the code harder to read and more complicated.
Instead of using Optional, I'm making the parm a Variant and passing Null when
it's not used.... then checking for "If Len(theParmValue & "") > 0... to see if
it is present.
That way I can eliminate checks for IsMissing(theParmValue)...

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"

Does C#2.0 support optional parameters like VB.NET:
Function MyFunction(Optional ByVal isCenter As Boolean = False)

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.

I got a similar idea a couple of months ago, but now this one will require
no change to the clr, is relatively easy to implement and would be a great
addition to C# 3.0 :)
so here we go..
To make things simpler and better readable I'd make all default parameters
named parameters so that you can decide for yourself which one to pass and
which not, rather than relying on massively overlaoded methods which
hopefully provide the best...

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.

I'm working on creating a WebService / WebMethod to receive a record
in real time from another system. The record contains about 20
fields. 10 of which aren't required.
I was planning on just making a method with 20 parameters. But, I see
there is no way to make an "optional" c# parameter. I was just
wondering if anyone had an suggestions on how to implement this? The
parameters are all different primitive types (int, string,...

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...

My problem is this (apologies if this is a little long ... hang in there):
I can define a function in VB.NET with optional parameters that wraps a SQL procedure:
Sub Test(Optional ByVal Arg1 As Integer = 0, _
Optional ByVal Arg2 As Integer = 0, _
Optional ByVal Arg3 As Integer = 0)
' Call my SQL proc with the same signature

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
