On approximately 3/21/2008 4:49 AM, came the following characters from
the keyboard of Doug Hoffman:
> I have been trying to understand how to get the -name of a button that
> was clicked by the -onClick event, at the subroutine.
>
> I have read the win32::Gui docs over and over, read several post here
> and elsewhere, but I still don't get it yet. :)
> Please bear with me, I am trying to learn, but you know how that goes.
> You don't get it and then all of a sudden it's all perfectly clear and
> you wonder why you thought it was that difficult to begin with. My
> brain seems to work really well by looking at working examples and
> then figuring out how things work, but I haven't found a written

> Anywho. here is what I have, please be gentle :)

> I am creating a bunch of buttons on the fly from an array that is read
> from a file.
> All the buttons go to the same subroutine
> At the subroutine I want to know the -name of the button that was
> pressed and then go from there once I know the button -name.
> I have no problem getting all the buttons to display and go to the
> sub, the code all seems to work fine.

> Here's the basics of the button code and the button onClick sub
> $Main is my window
> $ButtonName comes from an array using a foreach loop and is a unique name
> $ButtonNumber comes from an array and is a unique name but not the
> same as $ButtonName

> That's where I am lost, *how exactly* do I get the first parameter

> Can anyone help me with a bit of code in where my question marks are
