[Gambas-user] Gambas Help - PLEASE - Object Arrays - Need help ASAP

[Robert Moss]

OK,   //CODE EXAMPLE AT END OF MSG

I have a subclass of Socket, Which is a socket, but contains some extra
data, so that in the event handler, I have more than just the TAG property
to work with.

It seems that I cannot have a dynamically sized array.

When i try putting:

PUBLIC mySW[] as SWSocket

At  the top of the form class, it says "Arrays are forbidden here"
And if I declare it like:
Sub Form_Open ()
    DIM mySW[] as SWSocket


it says syntax error.

It's requiring me to set an array size, which isn't good, and on top of
that, I cannot access the socket outside of that function (and i believe the
sockets are destroyed once the open sub ends)

I'd like a button on the form that works like this

PUBLIC SUB btnAdd_Click()
    mySw[iNextSw] = new SWSocket;
    mySw[iNextSw].DoSomeMethod()
    INC iNextSw

END

'With a timer that does:

PUBLIC SUB Timer_Tick() 'or whatever it is, not important
    DIM X as Integer
    FOR X = 0 TO (iNextSw - 1)
        mySw[X].SendData
    NEXT
END

How can I do this?
