	HICON hicon;

// 1) to load from application resources
	HICON hicon=AfxGetApp()->LoadIcon(IDR_MAINFRAME);

// 2) to then draw that icon
	pDC->DrawIcon(0,0,hicon);


// 3) to load from an .ico disk file
	hicon = (HICON)LoadImage(
		NULL,				// handle of the instance that contains the image
		"Wzd.ico",			// name or identifier of image
		IMAGE_ICON,			// type of image-- can also be IMAGE_CURSOR or IMAGE_ICON 
		0,0,				// desired width and height
		LR_LOADFROMFILE);	// load flags-- with LR_LOADTRANSPARENT makes transparent to bkgrnd

// 4) to draw
	pDC->DrawIcon(50,50,hicon);

// 5) when loaded using LoadImage(), you must destroy icon:
 	DestroyIcon(hicon);

// 6) to load from an exe or dll file
	HINSTANCE hinst=AfxGetInstanceHandle();
	hicon=ExtractIcon(hinst,"Debug\\wzd.exe",1); // gets the second icon (-1 returns # of icons)

// 7) draw and destroy as before
	pDC->DrawIcon(100,100,hicon);
	DestroyIcon(hicon);
