Late Binding Issue

[Miro]

VB 2003 and Im still new to vb, so i hope i can explain this as best I can.

I have a variable defined as such: ( simple example )

Dim AVariableOfSort s(,) As Object = _
{ _
{"Last", "String", 20}, _
{"First", "String", 20} _
}


I had to define it as an object so I can have different variable types all
within the same array.
( unless there is another way to do this )

What im getting is an error "Option Strict On Disallows Late Binding" when
I try to do anything with an array element.

For example
AVariableOfSort s(1, 1) = ""

I would like to keep Strict On on

What am I missing ? or how do I get around this issue?

I beleive I know the difference between binding. - Simply put:
1. Dim X as String is early binding and Dim X as Object ,...
X.GetType.ToStr ing would be late binding and would
take longer during running.

Im not sure what to search for in Help / or Online to help myself out.

Thanks

Maybe it's better to define a class with properties for the first and second
string and the integer number. Then you can create an array of this type
('Dim Items() As Foo').

RE: Late Binding Issue

You can try using an ArrayList

Dim listOfObjs As ArrayList = New ArrayList

listOfObjs.Add( "Last")
listOfObjs.Add( "String")
listOfObjs.Add( "20")

However, I like Herfried's idea better in creating a class for this
information and then having an array (or a strongly typed collection) for
them. It really depends on what you are trying to accomplish.

Re: Late Binding Issue

Yes Herfried is right. Go for a class anc collections. Forget about
bidimensional arrays of objects. I have never seen them in a meaningul
..net program.

Re: Late Binding Issue

Ive never used classes in the programming languages ive used.

So that is my next lesson.
I stayed away from the array lists cause I didnt like how all the items have
to be the same "var type "

I just want to store a whole bunch of data in 1 variable with many different
vartypes and change the
variable elements as i need to.

Someone once pointed me on this newgroup to the object, so now im at the
point to use the "object" var
i created and im running into this.

So a class it will be - as long as i can achieve the above posted.
I can always make something like "dim bla(,) as String" and strigify
everything and val it as i need to cause i know
which elements are going to be numeric.
I just didnt think it would be this hard to store different variable types
/ variables all in one array.

So im off to read about classes .... my next post might be about them :)

Thanks.

Hi Miro. This is not a poetry.

Classes must be your breath.

Arraylist, Hashtable, Sorted List,
your father, mother and brother.

Comparers your best friends ...

Anyone wants to add more lines ? :)

Re: Late Binding Issue - almost OT

Believe it or not they arent the easiest thing to grasp.

In theory or on a page or in a book they are fine... but i tell ya
some old languages ive used far too long probably look just as confusing
back.

I will breath Classes this weekend,
and most likely have some questions.

Comparers and friends are still not all that clear either.

Re: Late Binding Issue

Miro,

Reading your message is the answer, you should not use a programming
language as VB.Net, C#, C++ or Java.

Just keep it by VB script or JavaScript.

Just my thought reading your message.

Re: Late Binding Issue

I would like to do it all in VB.
Learn it all as one of you would actaully do it in vb.
I knew javascript pretty good back in 99' to about 2002 ... and then i
stopped using it. So Im not sure how much
it has changed since then.

Im fiddling with classes now and I can create a Class and property so im
close ( or i think im close ).
So Im assuming now that I can create property's when im all done I will have
1 Class with 3 properties that will be an array,
that will technically be each element of the array i was trying to create.

M.

ps...
Oh... Herfried K. Wagner... the
DirectCast(AVar iableOfSorts(1, 1), String) = "" didnt work, it had the same
issue with late binding or something.

Re: Late Binding Issue

Miro,

If you create a class, something as

\\\
Public Class whatever
Private whatevervalue as string
Private whateelsevalue as string
Public property TheFirstValue as string
Get
return whatevervalue
End Get
Set (by value as string)
whatevervalue = value
end set
'The same for secondvalue
End Class
///

Than you can do
Dim myArray as list of (whatever)

all typed in this message so watch typos or other errros.

I hope this helps,

cor
