Strangely, at Microsoft.com, the current link to the Microsoft Windows SDK appears to be broken: http://msdn.microsoft.com/en-us/windows//bb980924.aspx?wt.svl=more_downloads[^]

The include file "tmschema.h" is part of the Microsoft SDK (in v6.0 and v7.0), and is included by Visual Studio 2010 (in afxwin.h). However, Visual Studio 2012 doesn't appear to have the correct include files and/or libraries. I'm looking to see if there's a known solution, and I'll post here again when I've worked it out! :confused:
