Just got an MSDN subscription and have been installing VC8 and related
apps. Now I'm starting to port my VC6 dll code... get the following
errors:
1>c:\program files\microsoft visual studio 8\vc\include\cstdio(37) : error
C2039: 'sprintf' : is not a member of '`global namespace''

1>c:\program files\microsoft visual studio 8\vc\include\cstdio(37) : error
C2873: 'sprintf' : symbol cannot be used in a using-declaration

1>c:\program files\microsoft visual studio 8\vc\include\cstdio(40) : error
C2039: 'vsprintf' : is not a member of '`global namespace''

1>c:\program files\microsoft visual studio 8\vc\include\cstdio(40) : error
C2873: 'vsprintf' : symbol cannot be used in a using-declaration

1>c:\projects\quadraspec\quadraspecbeta\software\quaddll_v8\quaddll.cpp(200)
: error C3861: 'sprintf': identifier not found

With a little research it looks like STL errors but makes no sense, why
sprintf and not sscanf, why vsprintf and not vprintf?

Also tried:
using namespace std;

With no effect,

and I tried:

std::sprintf( q.m_cXemASerialNumber, "%s", q.csBuff);

with the additional result:
1>c:\program files\microsoft visual studio 8\vc\include\cstdio(37) : error
C2039: 'sprintf' : is not a member of '`global namespace''

1>c:\program files\microsoft visual studio 8\vc\include\cstdio(37) : error

1>c:\program files\microsoft visual studio 8\vc\include\cstdio(40) : error

So now, Help!!!

Something is fundamentally wrong here. cstdio includes stdio.h which
indeed defines these names in the global namespace. Try the one-line
program:

#include <cstdio>

and see if you get the same errors. If so, the preprocessed output (/P to
make a *.i file) should reveal whether stdio.h is indeed being included
and indeed declares sprintf and vsprintf.
