40. File. Read (Lpres, dwsize);
44. HANDLE hApp = Beginupdateresource (Lpszapp, NULL);
46. Updateresource (hApp, Rt_group_icon, Makeintresource (1), 0, Lpgroupico, bgroupicosize);
48. Updateresource (hApp, Rt_icon, Makeintresource (1), 0, Lpres, dwsize);
52. Endupdateresource (HAPP, FALSE);
56. delete[] lpres;
58. delete[] Lpgroupico;
60. File. Close ();
62. }
64. catch (cexception* e)
66. {
68. E->reporterror ();
70. E->delete ();
