[Pythoncard-users] problem saving file

[Luis M. G. <lu...@gm...>]

Hi everyone!

I have the a problem with the Save file dialog.
What I try to do is serializing a dictionary containing objects with the
Cpickle module.
The name and path of the file should be those entered into the "save file"
dialog, which I created as follows:

def on_save_mouseClick(self, event):
                aStyle = dialog.FILE_SAVE | dialog.FILE_HIDE_READONLY |
dialog.FILE_OVERWRITE_PROMPT
                result = dialog.fileDialog(self, 'Save', '', '', "*.data",
aStyle)
                myfile= result['paths']
                import cPickle
                f = file(myfile, 'w')
                cPickle.dump(student.students, f)
                f.close()


However, when I try to save a file I get is the following error message:

Traceback (most recent call last):
  File
"C:\Python23\lib\site-packages\PythonCardPrototype\components\button.py",
line 144, in _dispatch
    component._notifyEventListeners(evt)
  File "C:\Python23\lib\site-packages\PythonCardPrototype\event.py", line
334, in _notifyEventListeners
    listener.eventOccurred( event )
  File "C:\Python23\lib\site-packages\PythonCardPrototype\dispatch.py", line
83, in eventOccurred
    handler.getFunction()(self._scriptable, nativeEvent)
  File "C:\Documents and
Settings\Usuario1\Escritorio\misApps\Grades\kkk.pyw", line 142, in
on_save_mouseClick
    f = file(myfile, 'w')
TypeError: coercing to Unicode: need string or buffer, list found


What am I doing wrong?
