The general operation, load open the image in the DOC, in the VIEW of map

 
#include  

The class CSDI1Doc: public CDocument 
{
Public: 
CImage m_Image; 
Virtual BOOL OnOpenDocument (LPCTSTR lpszPathName) 
{
if (! CDocument: : OnOpenDocument (lpszPathName)) 
return FALSE; 

//load the picture 
M_Image. Destroy (); 
If (m_Image. Load (lpszPathName)!=S_OK) 
return FALSE; 

Return TRUE; 
} 
. 
}; 

//CSDI1View map 
Void CSDI1View: : ontouch * pDC (CDC) 
{
CSDI1Doc * pDoc=GetDocument (); 
ASSERT_VALID (pDoc); 
if (! PDoc) 
return; 

//draw 
if(! PDoc - & gt; M_Image. The IsNull ()) 
{
CRect rc; 
GetClientRect (& amp; Rc); 
PDoc - & gt; M_Image. The Draw (pDC - & gt; M_hDC, rc); 
} 
}
