How to add your own function in MFC

天天向左

I wrote a program in C language, but the teacher asked us to use MFC to integrate the interface display, but I know very little about MFC, and my program itself has many functions to jump around, I do n’t know how to change Add your own program to MFC. . .
So please enlighten me masters, I am very anxious for your reply ....

The declaration is placed in the .h file, and the function body is placed in .cpp

Can you be more specific? For example, I have the following function:
#include <stdio.h>
int a, b;
int add ()
{
  int ss;
  ss = a + b;
  return ss;
}

void main ()
{
  a = 1;
  b = 2;
  s = add ();
  printf ("% d", s);
}

So now I use the project named ADD, based on the dialog MFC interface, which a.b should be placed in a. Which .cpp is the function body? Can you make it clear?

MFC is C ++,
You are using C,
Don't force it, forget it, it is recommended to learn C ++ first, and then see << MFC

In fact, I also know that it is a bit reluctant, but the teacher asked for the MFC integrated interface to display it. There is no way ~~ And now the time is very tight, where is the time to look at C ++ ~
But I only need to display the results of my own program operation, should I not delve into it? Ha ha. . .

This is not easy, just look for a simple example on the Internet and see

One build one Single documnet (single document project)
2. Put the add (int a, int b) function in the view cpp (don't forget to declare)
int add (int a, int b)
{
  int ss;
  ss = a + b;
  return ss;
}
Three call it in void CDrawTextView :: OnDraw (CDC * pDC) function
void CDrawTextView :: OnDraw (CDC * pDC)
{
CDrawTextDoc * pDoc = GetDocument ();
ASSERT_VALID (pDoc);
    
CString str;
str.Format ("% d", add (2,4));
pDC-> TextOut (1,1, str);
// TODO: add draw code for native data here
}

Oh, ah, it seems a bit understandable, thank you ...
But what if I want it to update every ten seconds
