I think it does, rssreader is fine with wxString and wxDateTime.

In MainFrame.h
struct Company
{
  int m_compName;
};

In MainFrame.cpp
#include <litwindow/dataadapter.h>
using namespace litwindow;
BEGIN_ADAPTER(Company)
    PROP(m_compName)
END_ADAPTER()

I got exactly the same result, everything compiled and then had trouble
linking.

I had an extra unresolved external.

I am using the debug lib version of litwindow on XP SP2, VC++6, wx2.5.3,
and STLport (sorry for not including that basic info)

I saw that on the litWindow website - can only be a good thing :)

I'm sure that this problem is to do with me, but I'm stumped as to what
it is - I am linking to both lwbase_md.lib and lwwx_md.lib.
