I've tried to use the 'progress indicator' to update on a peace of code.
Thing is, in the exercise (from J. Walkenbach) the Main procedure adds random
numbers. What I would like to do is whenever I activate commandbutton1 or
commandbutton2 (both buttons to be found in userform2) the progress inidcator
pops up. I however have no singel clue how to get about. I enclosed a copy of
my file.

Sheet TrimAll = where all the action happens
Sheet2 = Not used
Sheet3 = Not used

Userform1 pops up whenever you select the sheet. It asks the user if he/she
wants to delete HTML non-breaking spaces or not. If the user chooses to
delete the HTML non-breaking spaces Userform2 turns on. In this Userform (2)
the user can decide wether to adjust the whole package of data or just a
selection (using an inputbox). Now comes the tricky part (to me); in both
cases (so whenever a user chooses to adjust everything or just a selection)
I'd like to have a progress indicator displayed to them. Can you help me with
this (or just get me started)?!

I you need code referring to commandbutton 1 and 2, see below

Private Sub CommandButton1_Click()
Application.DisplayAlerts = True
Application.EnableEvents = True 'should be part of Change Event macro
If Application.Calculation = xlCalculationManual Then
MsgBox "Calculation was OFF will be turned ON upon completion"
End If
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
'Select active content
Range("A2").CurrentRegion.Select
Dim cell As Range
'Also Treat CHR 0160, as a space (CHR 032)
Selection.Replace What:=Chr(160), Replacement:=Chr(32), _
LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:=False
'Trim in Excel removes extra internal spaces, VBA does not
On Error Resume Next 'in case no text cells in selection
For Each cell In Intersect(Selection, _
Selection.SpecialCells(xlConstants, xlTextValues))
cell.Value = Application.Trim(cell.Value)
Next cell
On Error GoTo 0
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub

Private Sub CommandButton2_Click()
Dim rng As Range
On Error Resume Next
Specify = Application.InputBox _
(prompt:="Specify a range", Type:=8).Select
Dim cell As Range
'Also Treat CHR 0160, as a space (CHR 032)
Selection.Replace What:=Chr(160), Replacement:=Chr(32), _
LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:=False
'Trim in Excel removes extra internal spaces, VBA does not
On Error Resume Next 'in case no text cells in selection
For Each cell In Intersect(Selection, _
Selection.SpecialCells(xlConstants, xlTextValues))
cell.Value = Application.Trim(cell.Value)
Next cell
On Error GoTo 0
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub

Private Sub CommandButton3_Click()
Unload UserForm2
End Sub

Private Sub UserForm_Click()

End Sub
