Re: [Mingw-users] win32 and a STM_SETICON (STM_SETIMAGE) problem

[Alessandro A. <ant...@gm...>]

In fact. I never been able to make this think work as Microsoft says it works.
If you need to use a STATIC control that shows an icon image you should use:

CTEXT   IDC_IDENTIFIER, x, y, cx, cy, SS_ICON | SS_CENTERIMAGE |
SS_REALSIZEIMAGE

Afte that you can use LoadImage()/SendMessage() pair to set the icon.

Best regards,
Alessandro Antonello.
