[IronPython] Can't install IronPython Tools for Visual Studio

[Curt Hagenlocher]

The problem is this line:
controls['Button']['btnCreate'].Click += printHello("HELLO WORLD")

This executes the function printHello("HELLO WORLD") and tries to add the
result -- None -- as an event handler. Something like the following should
probably work:

 controls['Button']['btnCreate'].Click += lambda s, e: printHello("HELLO
WORLD")
