Can I (and how) read the caption of a button?

I know how to place a text on a button.
Can I read it too?

The GetWindowTextA() API call can do it.

button #m.b, "testing", [testing], UL, 10, 10
open "blah" for window as #m

hButton = hwnd(#m.b)

print GetWindowText$(hButton)
input a
close #m

[testing]
wait

Function GetWindowText$(hWnd)
   bufLen = 256
   buf$ = space$(bufLen)

   CallDLL #user32, "GetWindowTextA",_
   hWnd as ulong,_
   buf$ as ptr,_
   bufLen as long,_
   ret as long

   GetWindowText$ = left$(buf$, ret)
End Function

Hello Chris,

Thanks for your help.

You could as well keep an array of the current button name and simply reference that. Change the button text, change the array, or more simply use the array element as the button text.
