Dear experts,

I have an MFC program that displays lines of text in a view. But I would need to display pictures besides the text. Is there any simple way to do that?

Thanks.

It can be done in virtual OnDraw. But then, difficulty level depends on image type. If this is a bmp, no concern. If you want to display a jpg or a gif, there's no standard function, you must use an external library.

If you need to read a JPEG, GIF, orBMP, you can use the MFC class CImage.  
However, CImage uses GDI+.  That means the resulting application won't run on a Windows operating systems that pre-dates XP without downloading some sort of an update.

@HooKooDooKu : you're right...I've forgotten CImage improvements.

Then, solution should be:
class CMyView : public CView
{
protected: // create from serialization only
	CMyView();
	DECLARE_DYNCREATE(CMyView)

// Overrides
public:
	virtual void OnDraw(CDC* pDC);  // overridden to draw this view
// Implementation
public:
	virtual ~CMyView();
// Generated message map functions
protected:
	DECLARE_MESSAGE_MAP()

 CImage m_Image ;
};

CMyView::CMyView()
{
    m_Image.Load("myImage.jpg") ;
}

void CMyView::OnDraw(CDC* /*pDC*/)
{
   m_Image.Draw(pDC->GetSafeHdc(), 0, 0) ; // consider overrides if you want to stretch image
}

Open in new window
