Thanx for the answer ... I really want to 'remove' the checkboxes/label/comboboxes and add new ones ..... (the checkboxes and labels are added according to what was selected in one first combobox and when a checkbox is checked on/off I add/remove other comboboxes ... but this is the project logic)

I used:

Win32::GUI::DestroyWindow($Window->$name);

where  $name is the name of the label/checkbox or combobox I want to remove.
