Set icon for a popup CFrameWnd window

Hi all,

I am trying to set the 16x16 icon for a popup frame window.  I load the
icon using 

	HICON myIcon = AfxGetApp()->LoadIcon(ICON_ID);
and then set it using 
	
	SetIcon(myIcon, FALSE);

However, when I run my application and display my popup window, the icon on
the upper left corner of the caption bar is the 32x32 icon reduced, and
looks bad.

I am sure I have an icon with both 16x16 and 32x32 formats in my resources.

Any insights on what is going on?

Yes- you need to use LoadImage() to load the icon. CWinApp::LoadIcon() [as
the documentation states, BTW] will ONLY load icons that are SM_CXICON
pixels wide and SM_CYICON pixels high. LoadImage(), however, allows you to
load alternate icon sizes. Here's some code showing how to load the 16x16
image:

  ...
  hIcon = (HICON)::LoadImage( ::AfxGetInstanceHandle(), 
                                MAKEINTRESOURCE( IDR_MAINFRAME ),
                                IMAGE_ICON, 16, 16,
                                LR_DEFAULTCOLOR );

Again, if memory serves me, this would be a doc. bug since it actually uses
the 32x32 icon...

CWinApp::LoadIcon will try to load the 32x32 icon in your ICON_ID =
resource first. You could either try doing LoadIcon on a icon resource =
containing only a 16x16 icon, or use LoadImage instead.
