Statusbar with progressbar *RESOLVED*

[vbdotnetboy]

i have created a class inherits the statusbar so that i can add a progressbar to it. you can also add date and time to the statusbar. however i don't want the progressbar display right away. no problem with that. no problem displaying it the FIRST time, but then lets say i remove the progressbar and then try to add it to the statusbar again and i get an exception, "Object already has parent." I have no idea what i'm doing wrong. as of right now i've been testing to make sure i can display and then remove the progressbar with two buttons. after i get it working it will be display and removed by events...if i can get by this exception... any help would be great


Code for the class

Public Class StatusProgress : Inherits StatusBar

    Private _pbPanel As Integer = -1

    'Format for date and time.
    Private DT_Format As String = "MM/dd/yyyy"
    Private Tmr_Format As String = "h:mm tt"
    'Timer to control time and seconds.
