hello im trying to do some simple math in a dlg window in msvc++ 6.
anyway what i want to do is get 2 numbers input from a user multiply the first by 1 and the second by 1.5 and display the results. but it keeps putting them as 0. i am a newbie so i maybee doing this the wrong way.
btw i know it seems pointless to be multiplying something by 1 but i this is just the number i want to use while figuring the program out.
here is the code:
Code:
// battlesimv2Dlg.cpp : implementation file
//
#include "stdafx.h"
#include "battlesimv2.h"
#include "battlesimv2Dlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
