Hiding an MFC dialog box

Question

Ok so I am using this code to hide the taskbar icon of a dialog based MFC application(VC++). The taskbar icon and the dialog box hide whenever I click on the cross or the close

Answer 1

Maybe an obvious thing, but what happens when you do the hide before you reparent the dialog? Also what if you don't directly modify the window style but use ShowWindow(SW_HIDE)?

Finally, have you tried switching the dialog's window style to WS_CHILD before calling SetParent() and/or maybe moving it out of the client area so that the window isn't shown any more (MoveWindow(-1000, -1000) or something like that).
