If you need this to work on Windows - take a look at pyHook:

As Luke has stated... it's possible to stop the key presses from reaching their
target application. If you do use pyHook, make sure your functions always return
True (this allows the key press to hit it's destination).

Re: [Tutor] how do I find where my program is installed?

Here's what I do in my py2exe app:

installDir = os.path.dirname(os.path.abspath(sys.argv[0]))

and take a look at this link:

Hi Kent,

I just tested the following code and it works like a champ :-)

filename = r'C:\TEST.ps'

old = '''<<
  /Policies <<
/PageSize 3
  >>
>> setpagedevice'''

new = '''<<
 /EndPage
  {  exch pop
 0 eq
{  gsave
  initmatrix
  save
850 1250 moveto 45 rotate 0 setgray
/Helvetica 25 selectfont (CAUTION - DO NOT SCALE!) true charpath .2
setlinewidth stroke
  restore
  true
  }
 { false }
 ifelse
  } bind
>> setpagedevice'''

f = open(filename)
data = f.read()
f.close()
newData = data.replace(old, new)
f = open(filename, 'w')
f.write(newData)
f.close()

Thanks again for your help!!
