vs2005 VC++ question - %n format specified disabled

[NuclearNed]

I'm still using VS2003, but I'm helping a coworker learn VC++ w/ MFC on VS2005. It appears that the %n format specifier for CString and printf has been disabled for security reasons.

So now what is the proper way to format integers as strings?

Well here is one quick way to do it:

#include <stringstream>

wstringstream conv;
CString cstr;

int n = 1234567;

conv << n << ends;
cstr = conv.str();

Note: from memory, as I don't have a compiler on this machine. You might have to do:

cstr = conv.str().c_str() depending on what conversion methods a CString supports.

There are probably a dozen other ways to do this, as strings in Windows/C++/STL/ATL/MFC is probably the most farked up area of system development, but that is the one I currently use.

Use old printf standby formatting codes.

%d
%ld

ostringstream defined in iostream in the "std" namespace will do what you want
