it works fine, here's the code. Thank you ck.
But I think to make without global variable, if it is possible.

> " But I bet there's an easier way. ;) ". (ck)

I must find that way.
Steve.

without warning
include win32lib.ew
sequence dlgResult, result
dlgResult = ""

constant WIN = createEx( Window, "YesNo Dialog", 0, Default, Default, 400,
220, 0, 0 )
constant YesB = createEx( PushButton, "Click here", WIN, 40, 48, 100, 24, 0,
0 )
constant SB    = createEx (StatusBar, "", WIN, 0, 0, 0, 0, 0, 0 )

constant win_Main = createEx( Window, "YesNo Dialog", WIN, Default, Default,
192, 120, 0, 0 )
constant LText2 = createEx( LText, "What's your answer?", win_Main, 40, 16,
160, 20, 0, 0 )
constant bttn_Yes = createEx( PushButton, "Yes", win_Main, 40, 48, 52, 24,
0, 0 )
constant bttn_No = createEx( PushButton, "No", win_Main, 100, 48, 52, 24, 0,
0 )


procedure onClick_buttons(integer self, integer event, sequence params)
if self = bttn_Yes then
	dlgResult = "Yes"
	setText(SB, dlgResult)
else
	dlgResult = "No"
	setText(SB, dlgResult)
end if
closeWindow(win_Main)
end procedure
setHandler({bttn_Yes, bttn_No}, w32HClick, routine_id("onClick_buttons"))

function runDialog( )
    openDialog(win_Main)
    return dlgResult
end function

procedure onClick_YesB(integer self, integer event, sequence params)
    result = runDialog()
    setText(SB, dlgResult)
end procedure
setHandler(YesB, w32HClick, routine_id("onClick_YesB"))

WinMain(WIN, Normal)

You could create a function which wraps a openWindow() call like this:


sequence dlgResult

-- build an input dialog
constant win_Main = createEx( Window, "YesNo Dialog", 0, Default, Default,
192, 120, 0, 0 )
constant LText2 = createEx( LText, "What's your answer?", win_Main, 40, 16,
116, 20, 0, 0 )
constant bttn_Yes = createEx( PushButton, "Yes", win_Main, 40, 48, 52, 24,
0, 0 )
constant bttn_No = createEx( PushButton, "No", win_Main, 100, 48, 52, 24, 0,
0 )

-- create functions to set variable result
-- i.e., for bttn_Yes_OnClick, setResult="Yes"
-- i.e., for bttn_No_OnClick, setResult="No"

function runDialog( sequence win )
    openWindow(win,Normal)
    return dlgResult
end function

Then

    result = runDialog( win_input )

But I bet there's an easier way. ;)

I think he didn't want to be confined to just "Yes" and "No" responses.
With this method, you could also return the state of checkboxes, etc...

x = runDialog( myDialog )
-- x now might equal {"Yes","No","Maybe",3,0}
