dllcode.cpp

学习运用MFC封装类的DLL,可以实现GUI 的通用性.

#include "StdAfx.h"
#include "DLLCode.h" 

int DLLfun2(int a) { return a<<1; }; 

int DLLArg = 100; 

DLLclass::DLLclass() {}; 
DLLclass::~DLLclass() {}; 

int DLLclass::Add(int a, int b)
{
	return a + b;
}; 

int DLLclass::Sub(int a, int b)
{
	return a - b;
}; 

void DrawEllipse ( CRect rect, CDC *pDC )
{ 
	CBrush brush;
	brush.CreateSolidBrush(RGB(0,0,255));
	pDC->SelectObject(&brush); 
	pDC->Ellipse(&rect);
};
