Can anyone shed any light on this? I spent several hours searching the

Using VS2010, I built a little IronPython program and added a Windows
form to it as a separate project.
It all works fine when invoked as "ipyw.exe -D Program.py".
(IronPython 2.6.2 with .net 2.0)
Moving on to try out pyc.py, I built a trivial program (no separate
form) and the executable works fine.
(I used the sample that gets created when you create a new IP project
in VS2010.)
But when I try to build and run my version with the separate form, it
does not work; my compiled python can't find the DLL when run.
The exact error message is this:

The pyc.py build command is

I am building and running in a directory containing the DLL's,

Here is my Program.py

clr.AddReference('form.dll')
from ipform import Form1
form = Form1()
Application.Run(form)
Brian,
I haven't tried the pyc tool yet, (haven't needed to), but I have run
into similar problems just running under IPy and VS.
I suspect pyc'ing is a whole different set of issues.
But anyway, I have taken to always using the
clr.AddReferenceToFileAndPath(...) form for my extraneous dll's for that
reason.
I add a bin folder to my project and put all my dlls in it and then
reference them by filepath, e.g.:
clr.AddReferenceToFileAndPath(r".\bin\IPyScratchPad.dll")
I think the "clr.AddReference(...)" form is really only for well-known
.Net dlls.
It's spelled out pretty well here:
http://www.ironpython.net/documentation/dotnet/
Give that a try.
Best,
Dave
