\nTo build the window list, we enumerate\nthe contents of the IShellWindows<\/CODE>.\nFor each window, we get its window handle\nand current location\nand create a listview item for it.\nThe reference data for the listview item is the\nItemInfo<\/CODE>.\n<\/P>\n\nBOOL\nOnCreate(HWND hwnd, LPCREATESTRUCT lpcs)\n{\n g_hwndChild = CreateWindow(WC_LISTVIEW, 0,\n LVS_LIST | WS_CHILD | WS_VISIBLE |\n WS_HSCROLL | WS_VSCROLL, 0, 0, 0, 0,\n hwnd, (HMENU)1, g_hinst, 0);\n g_spWindows.CoCreateInstance(CLSID_ShellWindows);\n BuildWindowList();<\/FONT>\n return TRUE;\n}\n<\/PRE>\n\nOur creation function creates a child listview\nand fills it with stuff.\n<\/P>\n
\nAnd of course we clean up our objects when the items\nare deleted and when the window is destroyed.\n<\/P>\n
