Re: Re: How can I change size of GUI?

For what definition of 'did not work'? Seems perfectly fine to me. Just try to add the lines: root = Tk() Try adding a line like this: root.geometry("400x300+100+75") ... which means: "make the window 400 pixels wide and 300 pixels high, with the upperleft corner at point (100,75)"

Re: Eval Problem

Yes, Python is dynamic, but my server farm, in this era of big business screwing the client and cutting all services and customer support, uses such crappy hardware that all normal code breaks, so I am forced to find work-arounds. Here is more complete code: ourFile = string.split(__file__, "/") p
