Answer 1

您可以使用snprintf或std :: string进行串联。

Answer 2

If you are doing it a lot you might want to consider a function to make it quick and easy.

int MsgBoxPrint(HWND hWnd, int Type, char *Caption, char *Format, ...)
{
    va_list ArgList;
    char Temp[4096];

    va_start(ArgList, Format);
    vsnprintf(Temp, 4096, Format, ArgList); 
    va_end(ArgList);

    return MessageBox(hWnd, Temp, Caption, Type);
}

Then you would call it like so:

MsgBoxPrint(hdlg, MB_OK | MB_ICONINFORMATION, "Logon Message", \
     "Your password will expire in %d days", pwdexpirydays);
