Keep form caption ...but change Taskbar caption...how?

[RobDog888]

If I am not missing something, isn't this what you are trying to
accomplish. Form1 caption remains the same and the form
caption in the taskbar showing a percentage or something. Use
two forms and the first one is the main form with the
.ShowInTaskBar = False and the second form's .ShowInTaskBar =
True. Change form2 caption like percentage changing etc.

Option Explicit
'FORM1.SHOWINTASKBAR = FALSE
'NEED A TIMER - TIMER1 INTERVAL OF 1000
Private miPercent As Double
Private mbShown As Boolean
 
Private Sub Form_Load()
    miPercent = 0
    mbShown = False
    Form1.Caption = "This is Form1's static caption"
    Timer1.Enabled = True
End Sub
 
Private Sub Timer1_Timer()
    miPercent = miPercent + 1
    Form2.Caption = miPercent & "% Done"
    Form1.Show
    'MOVE FORM OFF OF SCREEN
    If mbShown = False Then
        Form2.Show vbModeless, Me
        Form2.Move -10000, -10000
        Form1.Show
        mbShown = True
    End If
End Sub

Form2 is just for the taskbar percentage caption.
Handel the click on the taskbar by minimizing the form2 thus re-
activating form1. The user can not activate form2.

Option Explicit
'FORM2.SHOWINTASKBAR = TRUE
Private Sub Form_Activate()
    Form2.WindowState = vbMinimized
    Form1.Show
End Sub

Is this right???
Just some basic logic. I'm sure with some subclassing you can make it cleaner.

Edit. Just realized that buggy suggested something similar.
