I used to use this in VC6 and it worked:

typedef struct
{
const TCHAR *m_pSeparator, *m_pName;
} SeparatorWithNameT;
IOMANIPdeclare( SeparatorWithNameT );
ostream& fp( ostream& o, SeparatorWithNameT pair );
OMANIP(SeparatorWithNameT) SepWithName( const TCHAR *pSep, const TCHAR
*pName );

But under Microsoft Visual C++ .NET 69462-270-0000007-18335 I get:
h:\Husky\HostPC\Loader\Mark1\Mark1\Utils.hpp(137) : error C2146:
syntax error : missing ';' before identifier 'SepWithName'

Where did OMANIP (and IOMANIP, for that matter) go, and what is the
new solution?

This is how you define your own manipulators:

struct SeparatorWithNameT{
    const TCHAR *m_pSeparator, *m_pName;
} SeparatorWithNameT;

basic_ostream<TCHAR>& operator<<(
        basic_ostream<TCHAR>& os, const SeparatorWithNameT& sep) {
    return os << sep.m_pSeparator << sep.m_pName;
}

SeparatorWithNameT SepWithName(
        const TCHAR *pSep, const TCHAR *pName) {
    SeparatorWithNameT sep = {pSep, pName};
    return sep;
}

cout << "Hello" << SepWithName(", ", "Bill") << endl;

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925
