I checked this out and it seems to work . . . I got poking around in the
win32.hlp file (look in the index under STM_SETICON and WM_SETICON) and
found out that the wparam sent with this function determines whether the
icon is set as the "large" or "small" icon for that window.

I'm not sure exactly what this is supposed to mean, but from a practical
point of view, I discovered that

  if I set it to be the small icon, it became the small icon in the upper
left of the window, and next to the program in the title bar--but the
(larger) icon used during task-switching (alt-tab) was unchanged.

  if I set it to be the large icon, then it set that icon to be the icon in
the upper left of the window, the taskbar, AND the larger icon seen during
alt-tab.

Upshot?  It might be nice to at least have the option to select "large" or
"small" icon.  (On the other hand, the other half of the setIcon procedure
which uses STM_SETICON doesn't have this option--or, apparently, need it .
. . . which makes some difficulties.)

PS--thanks for the quick update of win32lib on that nasty menu bug--it
seems to work fine now!

[New - Windows 95]

WM_SETICON
wParam = (WPARAM) (BOOL) fType;    // icon size (large or small)
lParam = (LPARAM) (HICON) hicon;   // handle of icon


An application sends the WM_SETICON message to associate a new big or small
icon with a window. Windows draws the big icon when the window is
minimized, and the small icon in the window's title bar.

Parameters

fType

Value of wParam. Specifies the icon being set. If TRUE, the message sets
the big icon. If FALSE, the message sets the small icon.

hicon

Value of lParam. Identifies the new big or small icon. If this parameter is
NULL, the
icon indicated by fType is removed.
