I'm trying to get text from the 'Message List Pane' of the Forte Agent
newsreader (specifically the Subject of a given message in the list: my idea
is to iterate through the messages in the list, grabbing the subject from
each). I've got a handle to the window, which is described by WinSight as
'OwlWindow' (class) and 'ListBrowser' (window title). It appears to be a
ListView.

I can successfully send WM_X messages to set the focus or send keystrokes,
but LVM messsages all fail. ListView_GetItemCount(Hwnd) always returns '0'
no matter how many messages are in the list. Sending the message
LVM_GETCOLUMNWIDTH always returns '1', no matter the width of the columns,
and though it should return '0' for a failure. I also tried various LB
messages. I'd say the root of the problem is that I don't know what the heck
this window is. It looks like a ListView, but I'm wondering if it is some
sort of custom control cooked up with OWL, in which case -- what can I do?

Setting aside the problems of getting data out of someone else's
application, which I think I understand, is there any way to get strings out
of a windowed control, without knowing or apparently being able to determine
what type of control it is?

I think the API function is called "GetWindowText" - it takes an HWND, so you 
don't need to know what kind of control you're getting the text from.

If it were just a normal window, as opposed to a list, I believe you'd be
able to read the text using the GetWindowText API. I have been able to use
tha in the past without any trouble, although not with list controls.


Good luck!!
