Hello, does anyone know how to change the child window''s background colour? And also, how to make the menu to display a child window''s min/mix box? ( i managed to make a child window, with WM_MDICREATE. But when it got maximized, there aren''t any restore or minimise box to click on, to put the child window back to normal size. Or should i use CreateWindow instead of WM_MDICREATE...? ) Thanks for helping
