But there is a sequence of Windows functions from:

	http://www.cplusplus.com/forum/general/28470/

summarizing (but this is from 2010 so may need tweaks):

"There are two icons in the window, 32x32 and 16x16.
If you want to change the the icon at the task bar and title bar you should do:

	hIcon = (HICON)LoadImage(NULL, "menu_two.ico", IMAGE_ICON, 32, 32,
LR_LOADFROMFILE);
	hIconSm = (HICON)LoadImage(NULL, "menu_two.ico", IMAGE_ICON, 16, 16,
LR_LOADFROMFILE);

LoadImage just loads the icon from the file. You need to assign the icon to the
window. You do this by sending a WM_SETICON message:

	SendMessage( yourwnd, WM_SETICON, ICON_SMALL, (LPARAM)hIconSm );
	SendMessage( yourwnd, WM_SETICON, ICON_BIG, (LPARAM)hIcon );

Reference: http://msdn.microsoft.com/en-us/library/ms632643(VS.85).aspx

I found out the difference with the ICON_SMALL and ICON_BIG, if you only set
ICON_SMALL then the Alt-Tab icon is stretched and looks bad.
If you set the ICON_BIG as well as ICON_SMALL, then everything looks nice."

For Xwindow icons, some approaches from google, depending on needs:
