sprintf_s downgrade possible ?

[PawelSokolowski]

Hi all,

I was not aware that VS2008 does not build NT 4.0 valid applications, and I
migrated from VS2003 to VS2008
Unfortunatelly one of my client still uses NT on about 200 computers, and
cannot upgrade to XP, they are simply too old.

While migrating I made about 1800 changes in code, and I don't really like
the idea of changing everything back.
Many of those changes were securing sprintf function.
sprintf(...) -sprintf_s(...)

Do you have some idea about compiling sprintf_s under VS2003 ???

I doule like to create a sprintf_s function, passing arguments to regular
sprintf.
Since it has variable list of arguments, I have a problem how to pass them.
I would appreciate any suggestions.
Regards
Pawel

Out of interest, what aspects prevent VS2008 built applications
running on NT4?

Hi David,

Out of interest, what aspects prevent VS2008 built applications
running on NT4?

The CRT (and possibly MFC) depend on newer versions of Windows.
Building a win32 app form scratch without CRT and MFC should still work.

In addition to what others wrote, you may consider also StringCchPrintf
function:

http://msdn.microsoft.com/en-us/libr...41(VS.85).aspx

it is available in VS.NET 2003, too.

HTH,
