Use instead:

      rndtxt = lookup_widget(wndRand, "rndbox");

This means: you're right, you must specify the parent widget (which is
wndRand).  What I don't see is who is "button"?

Also, from this code I understand you're using Glade to generate the
source code.  That's good, but may not work unless you selected "set
widget names" checkbox, somewhere in the project preferences dialog.

Yet another thing: Glade provides another (very powerful) way to load the
graphical interface: you save every window in a .glade file, which is
basically a XML file, and it provides a separate library which you can use
to load and show the widgets defined in that file.  This way you don't
mess with Glade generated code, which is sometimes hard to modify or
improve.  So, for more iofo about this check "libglade" --
http://glade.pn.org.
