Does my Visual C++ still have an 8-bit-char-mode set of library functions? If so, how to call them?

The "Not Set" should allow the project to use the ANSI functions. You've already made the correct change.

void diprintf(HWND db,int c,char*fmt,...)
{
    char C[256];
    vsprintf(C,fmt,(&fmt)+1);
    SetDlgItemText(db,c,C);
};

failed with this error:

1>faces.cpp(80): error C2664: 'int vsprintf(char *const ,const char const ,va_list)': cannot convert argument 3 from 'char *' to 'va_list'
1> faces.cpp(80): note: Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast


The debugger error tells you exactly what the problem is. The third argument needs to be a va_list. Those old unsafe typecasts are no longer legal.

You can probably fix it with something like:
void diprintf(HWND db,int c,char*fmt,...)
{
    char C[256];
    va_list arg_ptr;
    va_start(arg_ptr, fmt);
    vsprintf(C,fmt,arg_ptr);
    SetDlgItemText(db,c,C);
};

The function looks unsafe. The function will overflow if the variable-argument list results in a string longer than 256 char. You should consider using the safer vsprintf_s.
vsprintf_s(C,256,fmt,arg_ptr);

Best Wishes,
