Took me some time to spot the problem (I think):
C++
lpMapAddress =(LPTSTR)MapViewOfFileEx( hFileMap, FILE_MAP_ALL_ACCESS,
		                            0, 0, 0, lpdwParam );

This doesn't make much sense: the last argument of the function is the address where you want it mapped. So you are kind of mapping the memory where it was already mapped. I's suggest to change it to:
C++
lpMapAddress =(LPTSTR)MapViewOfFile( hFileMap, FILE_MAP_ALL_ACCESS,
		                            0, 0, 0);

If you want a shared memory implementation that has been tested, you can find one here. The source file is mlib/src/shmem.cpp
