Easy to get handle from listbox. How to get listbox from handle?

[IMAFriend]

Hello everyone. This maybe is easy, but I'm stuck.

I'm using visual basic.net. And this is with the enumwindows
function. But that isn't relevant.


If I have a sub that just simply will add an item to a listbox, but
takes the handle to the listbox as a parameter, how can I 'convert'
that handle back to a listbox?

It would look similar to below, except for the line that needs
fixing: lst = new listbox(lstHand le)
Any help? thanks bunches.

sub main
call addToList(listb ox1.handle, "hello")
endsub


sub addToList(lstHa ndle as intptr, txt as string)
dim lst as listbox
lst = new listbox(lstHand le)
lst.additem (txt)
endsub
