The following example demonstrates the use of CStringT::FormatV.
Its very simple to write a program for formatting the variables in Visual C++. Below is a sample

#include <string.h>
#include <atlsimpstr.h>
#include <atlstr.h>

void WriteString(LPCSTR pstrFormat, ...)
{
CString str;

// format and write the data you were given
va_list args;
va_start(args, pstrFormat);

str.FormatV(pstrFormat, args);
va_end(args);

printf(str);
return;
}

int main( )
{
WriteString("%d error(s) found in %d line(s)", 10, 1351);
}

thanks
