Is it possible to have a progress bar displayed on the screen to let the user know that something is happening?

Can you find out the more elegant way for me while I try this one
This operation is done the same way in Access'97. However there is an ActiveX control that can be used.
Here is information that I have just copied from the help file:
------------------------
The ProgressBar control shows the progress of a lengthy operation by filling a rectangle with chunks from left to right.
Syntax
ProgressBar
Remarks
· The ProgressBar control monitors an operation's progress toward completion.
A ProgressBar control has a range and a current position. The range represents the entire duration of the operation. The current position represents the progress the application has made toward completing the operation. The Max and Min properties set the limits of the range. The Value property specifies the current position within that range. Because chunks are used to fill in the control, the amount filled in only approximates the Value property's current setting. Based on the control's size, the Value property determines when to display the next chunk.
The ProgressBar control's Height and Width properties determine the number and size of the chunks that fill the control. The more chunks, the more accurately the control portrays an operation's progress. To increase the number of chunks displayed, decrease the control's Height or increase its Width. The BorderStyle property setting also affects the number and size of the chunks. To accommodate a border, the chunk size becomes smaller.
You can use the Align property with the ProgressBar control to automatically position it at the top or bottom of the form.
Tip To shrink the chunk size until the progress increments most closely match actual progress values, make the ProgressBar control at least 12 times wider than its height.
The following example shows how to use the ProgressBar control, named ProgressBar1, to show the progress of a lengthy operation of a large array. Put a CommandButton control and a ProgressBar control on a form. The Align property in the sample code positions the ProgressBar control along the bottom of the form. The ProgressBar control displays no text.
Private Sub Command1_Click()
Dim Counter As Integer
Dim Workarea(250) As String
ProgressBar1.Min = LBound(Workarea)
ProgressBar1.Max = UBound(Workarea)
ProgressBar1.Visible = True
'Set the Progress's Value to Min.
ProgressBar1.Value = ProgressBar1.Min
'Loop through the array.
For Counter = LBound(Workarea) To UBound(Workarea)
'Set initial values for each item in the array.
Workarea(Counter) = "Initial value" & Counter
ProgressBar1.Value = Counter
Next Counter
ProgressBar1.Visible = False
ProgressBar1.Value = ProgressBar1.Min
End Sub
Private Sub Form_Load()
ProgressBar1.Align = vbAlignBottom
ProgressBar1.Visible = False
Command1.Caption = "Initialize array"
End Sub
Distribution Note The ProgressBar control is part of a group of ActiveX controls that are found in the COMCTL32.OCX file. To use the ProgressBar control in your application, you must add the COMCTL32.OCX file to the project. When distributing your application, install the COMCTL32.OCX file in the user's Microsoft Windows System or System32 directory. For more information on how to add an ActiveX control to a project, see the Programmer's Guide.

docmd.runcommand [something]
I think the above should work, but if you want the runcommand way, I can probably find it for you later (no Access'97 on the computer I am sitting on at the moment)
