Remove the window from the task bar while in minimized state

[d_kilshtein]

My application uses a tray icon, which can open a dialog only if asked by the user. The rest of the time my dialog in the minimized state. How can I remove the window from the task bar while my dialog is in minimized state so the user will only see the tray icon? And how can I remove the menu that appears with the right click on the dialog’s icon (left top corner)?

To remove the button from task bar you can simply hide your window by calling ShowWindow(SW_HIDE);.
