L_VecLoadMemory failing with -9 when loading a DXF file

When trying to load a DXF file you may experience a failure of -9 Invalid File Format.  To overcome this error add the following of code before L_VecLoadMemory:

FILTERINFO fi;
memset(&fi, 0, sizeof(fi));
L_GetFilterInfo(TEXT("DXF"), &fi, sizeof(fi));
fi.uFlags |= FILTERINFO_CHECKEDBYFILEINFO;
L_SetFilterInfo(&fi, 1, 0);
L_FreeFilterInfo(&fi, 1, 0);

This will force the DXF filter to be used first to load the file.

Attached is a sample in VC 6.0, using MFC and LEAD's API Library.
