Does anyone know how to get a click on a radio button to notify the parent
window? BS_NOTIFY combined in the arguments on create don't seem to do it
id = create(Button,EUmenu[i][j][1],subMenuId[i],
col,row,lenRow,20,{BS_AUTORADIOBUTTON,BS_NOTIFY})
If I try this the buttons disappear.

I'm assuming you are using Win32lib.ew.
Wouldn't you just register the onClick event of the button
to call the handler for the window.
onClick[id]=routine_id("mainWindow_onClick")
you would then use the getSelf() to determine what id called
mainWindow_onClick. BTW change mainWindow to the name
of your window.
Also, shouldn't Button in your example be Radio?

Yes, Al it actually is a radio button. Here's the statement
id = create(Button,EUmenu[i][j][1],subMenuId[i],
col,row,lenRow,20,BS_AUTORADIOBUTTON)
The MS doc says that BS_NOTIFY for the button should notify the parent
window if it's clicked. I couldn't seem figure out how to get that to
happen. The reason I wanted the BS_NOTIFY to work is that there are about
12 windows each having 20 to 30 buttons.

George,
The MS Docs do not say that at all. I quote:
"BS_NOTIFY Enables a button to send BN_KILLFOCUS and BN_SETFOCUS
notification messages to its parent window.
Note that buttons send the BN_CLICKED notification message regardless of
whether it has this style. To get BN_DBLCLK notification messages, the
button must have the BS_RADIOBUTTON or BS_OWNERDRAW style.
"
It talks about focus notification, not click notification.
But back to your problem.
Can I suggest you use win32lib's create(Radio, ...) instead, and then use
the click handler for all your buttons. Something along the lines of :
sequence radiobtns, tags
radiobtns = {}
tags = {}
id = create(Radio,EUmenu[i][j][1],subMenuId[i],col,row,lenRow,20,0)
if length(tags) < id then
tags &= repeat(0,id - length(tags))
end if
tags[id] = {i,j}
radiobtns &= id
.
.
.
procedure ClickRadio(integer self, integer event, sequence parms)
-- You can then use tags sequence to quickly get the
-- original 'i' and 'j' values.
integer oi, oj, win
oi = tags[self][1]
oj = tags[self][2]
-- Get which window was just clicked.
win = subMenuId[oi]
. . .
end procedure
setHandler(radiobtns, w32HClick, routine_id("ClickRadio"))
---------
Derek.

Thanks, Derek. Your MS doc is the same as I was looking at. The proglem is
that I'm understanding about 1/2 of what I'm reading....or misunderstanging
most of what i'm reading. I'm not yet up to speed...obviously. Thanks for
all you help.
