[python-win32] Calling an OLE Automation (IDispatch) server which uses "out params"

[Mark Hammond]

That's very strange - is it possible you changed the source code since 
you sent it, or aren't using the latest pywin32?

This is what I see:

Python 2.7.3+ (default, May 12 2012, 13:50:02) [MSC v.1500 32 bit 
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import win32com.client
 >>> klass=win32com.client.gencache.GetClassForProgID("MyApp.Application")
 >>> klass
<class win32com.gen_py.3D28B651-27E2-4057-A0AF-1D761C2D10CCx0x1x0.MyApp 
at 0x02506960>
 >>> x = klass()
 >>> x.ShowMessage("Hello, world")
 >>> x.SetSettingValue("color","blue")
 >>> x.GetSettingValue("color")
u'color=testValue123'
 >>>

Given the source code, that last line is expected (ie, every value will 
return 'testValue123').

I'm at a bit of a loss on the problem you are seeing.
