[Py2exe-users] py2exe and pythondotnet

[Pierre Z. <Pie...@ps...>]

Hi all,

I have been using Python for .Net
(http://www.zope.org/Members/Brian/PythonNet/) to create a GUI for my
python code.  When it came time to pack the code into an exe, running
py2exe raised the following warnings:

"The following modules appear to be missing
['CLR.System.Drawing', 'CLR.System.Windows.Forms']"

The .exe was created, though, but running it immediately raised an
error:

"An unhandled exception of type 'System.IO.FileNotFoundException'
occurred in Unknown Module.
Additional information: Could not load file or assembly 'Python.Runtime,
Version=3D1.0.0.0, Culture=3Dneutral, PublicKeyToken=3Dnull' or one of it=
s
dependencies. The system cannot find the file specified."

This error is resolved by placing the file "Python.Runtime.dll" into the
dist folder just created.  Running the .exe then raised another error:

"Traceback (most recent call last):
  File "convertForm.py", line 6, in ?
ImportError: No module named System.Windows.Forms"

The code in question featured the following imports to handle the
importation of the requisite dotnet modules:

"import CLR.System.Windows.Forms as WinForms
from CLR.System.Drawing import Size, Point"

As the traceback made clear, py2exe wasn't resolving the (implicit)
importation of the requisite dotnet dlls.  All that was needed to
rectify this, however, was to add an explicit import of the CLR
namespace on its own line immediately preceding the other two imports:

"import CLR
import CLR.System.Windows.Forms as WinForms
from CLR.System.Drawing import Size, Point"

Now everything is working fine.  It still raises that first warning but
this can be ignored.

I hope this helps someone else,

Pierre
