You can use SendMessage to get the image handle from various controls in Microsoft Windows Common Controls 6.0 (Mscomctl.ocx). By using SendMessage, you can pass TB_GETIMAGELIST, LVM_GETIMAGELIST, TVM_GETIMAGELIST, or TCM_GETIMAGELIST to get the imagelist handle for the Toolbar, ListView, TreeView, and TabStrip controls.
However, when you do this on a computer running Windows XP, the wrong handle is returned. If you call any other APIs, and then pass this handle, those API calls will not function correctly.
This problem occurs because Windows XP and Mscomctl.ocx load two different versions of Comctl32.dll that are not compatible.
